CCTV News:This year is the Year of the Rabbit, and the fate of "Rabbit" and China in exploring space is really not shallow. Speaking of China’s lunar exploration, in the Chang ‘e project, the Yutu lunar rover brought us too many surprises.

On the occasion of the Lunar Year of the Rabbit, China’s lunar exploration space rabbit released its official Chinese and English names, namely "Rabbit Star" in Chinese and "To star" in English. "Rabbit Star" means "Jade Rabbit patrols the moon and sails the Milky Way". The lunar rover No.3 and No.4 in China is named "Jade Rabbit", and the name of "Rabbit Star" expresses its space characteristics and initial mission.

　　　　　　 The English name "To star" means that our journey is a sea of stars. The design of "Rabbit Star" itself embodies the integration of traditional culture and space science and technology, entrusts the Chinese nation’s dream of exploring the moon for thousands of years, and expresses the lofty vision of China’s space flight to the deep space of the universe in the new era.

On the occasion of the Spring Festival in the Year of the Rabbit, the Yutu-2 lunar rover in China’s lunar exploration project sent back the latest photographic works from the moon 380,000 kilometers away and sent a New Year greeting.

CCTV reporter Li Ning:During the Chinese New Year, there will still be many people sticking to their jobs, including the Yutu-2 lunar rover, which is conducting (scientific) exploration on the back of the moon 380,000 kilometers away. I am now in the operation control and scientific operation center of the ground application system of the National Astronomical Observatory, and this image from the moon seen in the picture is the latest return of Yutu II lunar rover. Above, we can see that the topography of the moon is bumpy. This is the rut mark that Yutu-2 has traveled. It climbed a hill in this area, and then it began to enter a relatively gentle road, and you can see very clear rut marks.

CCTV reporter Li Ning:The rut mark is next to an impact crater. How does it avoid it in this process? How to design a route for it?

Li Chunlai, deputy chief designer of the third phase of the lunar exploration project:The walking route of Yutu-2 is to get the position in front with its own navigation camera, and we have to restore and analyze a terrain before we can decide where it goes. It has a climbing ability of 20 to 30 degrees, but we find that the soil on the moon is loose, so we won’t walk in this extreme condition, and we also hope that its loss will be smaller and safer.

At present, Yutu-2 is located in the north-west direction of the landing site, with a linear distance of about 800 meters. The state of the lunar rover and the scientific load on it is all normal. During the Spring Festival of the Year of the Rabbit, researchers from the National Astronomical Observatory will work overtime with Yutu II to continue the lunar exploration.

Li Chunlai, deputy chief designer of the third phase of the lunar exploration project:We will also spend the New Year with Yutu II, and wish Yutu II great success in the new year.

Ouyang Ziyuan, Academician of Chinese Academy of Sciences, First Chief Scientist of Lunar Exploration Project;I wish you all good luck in the Year of the Rabbit and all the best. The Jade Rabbit in the Moon Palace will make greater achievements and make contributions to our lunar explorers.

Ground application system team of lunar exploration project:Jade Rabbit will accompany you in the Year of the Rabbit, and I wish you all the best.

As early as before the Qing court prepared for constitutionalism, the newspaper industry in China was actually quite developed. Newspapers, represented by Times, Ta Kung Pao, Times and Beijing Daily, are well-known in Beijing, Shanghai and Hong Kong. After the Qing court promulgated the Outline of the King James Constitution, the Constitutionalists set up newspapers and periodicals in various places. As of May, 1911, according to incomplete statistics, there were more than forty newspapers and periodicals that only held a constitutional position.

Constitutional newspapers in the late Qing Dynasty

Ironically, the constitutional imperial edict was promulgated on September 1, 1906, and on September 29, the same month, the Beijing dialect daily and the Zhonghua newspaper were blocked at the same time, on charges of "arbitrarily discussing state affairs, fabricating rumors, echoing bandit parties, and making irresponsible remarks." The real reason is that the Chinese newspaper published the news that the Qing court secretly executed two royalists who returned from Japan, while the Beijing Daily ridiculed the arrest of a Taiwan Province man who came to Beijing by mistake for Sun Yat-sen. Peng Yizhong, the newspaper owner, was exiled to Xinjiang on the grounds of murder.

In a word, the basic position of these newspapers is "asking the emperor for democracy". In the process of running a newspaper, it was frequently examined and interfered by the Qing court. Therefore, many newspapers have not existed for a long time. For example, Beijing Daily, sponsored by Wang Kangnian, was founded on March 28th, 1907, and was ordered to close by the Ministry of Civil Affairs on August 26th because of the case of Yang Cuixi. The organ publication "On Politics" of the Political News Agency was closed down less than 10 months after its publication.

The people who presided over the speeches in these newspapers were intellectuals in the transitional period. After the abolition of the imperial examination system in 1905, a large number of scholars either went to study in the West or participated in new schools or speech institutions in China. At that time, famous writers included Liang Qichao, Da Sheng, Xiong Fanyu and Gu Zhongxiu.

More than a dozen of the above 40 newspapers are related to Liang Qichao, either as writers or publishers. For example, every issue of Guo Feng Bao was edited by Liang Qichao and sent to Shanghai for printing, half of which were written by Liang. With these opinion leaders as the center, the Constitutionalists have formed a number of speech centers.

Constitutionalists first kept great hopes for preparing for constitutionalism. After the introduction of the official system reform plan in November 1906, their attitude changed. This administrative system reform is nothing more than abolishing several small departments and changing the names of several departments. In fact, it is still a change of medicine. For example, in the central ministries and commissions, the proportion of Manchu and Han officials changed from 50-50 to 60-40. Nanfang Daily is extremely dissatisfied with this, saying that "it is a trick of autocracy in the name of fake constitutionalism."

The first revolutionary newspaper

In the autumn of 1899, Sun Yat-sen sent Chen Shaobai to Hongkong to organize a newspaper to publicize revolutionary ideas. As the British Hong Kong government prohibited Sun Shi from entering the country, Sun Yat-sen had to buy machines in Japan to raise funds, and told Chen Shaobai to name the newspaper China Daily. China Daily was officially published in Hongkong on January 25th, 1900, with Chen Shaobai as the president and editor-in-chief. The newspaper published a journal and a journal at the same time, with a dozen columns. The most popular column for the general public is "miscellaneous", which is to publish popular jingles and jokes in China to satirize current events.

The China Journal was published until 1913. It is generally believed that it was not revolutionary in the early days, and many of its ideas were the same as those of the constitutionalists. Some early serial articles only advocated limiting monarchical power and expanding civil rights, but did not clearly advocate revolution. In August, 1900, the newspaper published Zhang Taiyan’s "Please Strictly Refuse Manchu People to Enter the National Assembly" and "Discarding Braids", and then began to advocate Manchu Revolution.

When the newspaper published Zhang’s article, it added a sentence, publicly calling the Qing government a "barbaric government", which clearly expressed the newspaper’s position. In 1903, Guangzhou’s Ling Poster accused the revolution of anti-Qing, and China Daily published an article to refute it. The two sides fought each other in writing for months, while revolutionary figures in Guangdong submitted their books to the newspaper, expressing their support for the newspaper, and the sales of China Daily increased greatly.

China Daily is not only an organ of speech, but also a propaganda organ of the Xing China Association. Revolutionaries often hold secret meetings in the newspaper office at 27 Stanley Street, Central, Hong Kong. The command post of Huizhou Uprising was also located here. In a word, China Daily not only advocates revolution, but even directly launches armed struggle, which is one of its major characteristics.

Another newspaper, The National, founded in Tokyo, is more revolutionary. The newspaper severely condemned the Qing government’s act of flattering foreign countries and betraying the country, accusing them of stealing peace and being willing to hand over sovereign territory to others. If China wants to stand on its own feet and China wants to be rich and strong, it is necessary to overthrow the Qing government and make a revolution. The newspaper also introduces the revolutionary thought and history of European and American bourgeoisie to readers. They pay special attention to the correction of the concept of communication, for example, to separate the "state" from the "imperial court" and to be nationals rather than slaves.

Sue reported: strict censorship of speech

Su Bao was founded on June 26th, 1896 by Hu Tiemei, registered with the Japanese Consulate in Shanghai by his Japanese wife, and written by Zou Tao. In the early days, it was a tabloid newspaper, which was sold to Chen Fan in 1898 because of excessive debts. Chen transformed it into a clear discussion newspaper, which criticized the Qing court. Later, Chen became close to Cai Yuanpei and joined the China Education Association. In 1903, Zhang Shizhao became the main writer of Su Bao, and there were even more anti-Manchu revolutionary remarks.

On June 22, this year, Su Bao published an article "Homicide", openly advocating violent revolution. The article said, "This enemy, with five million evil clowns, occupied our land, paid for food and clothing, paid taxes, killed my ancestors, annihilated my compatriots, ravaged my culture, and bound my freedom … Today’s homicidal, that is, revanchism."

On June 20th, two days earlier, Wei Guangtao, the governor of Liangjiang, had reported to Cixi the recent remarks of Su Bao, saying that Su Bao "published cloth fallacies" and ordered that Mi Na be banned. On June 29th, a police detective went to the newspaper office to arrest people, including Chen Fan, Cheng Jifu, Zhang Taiyan, Zou Rong, Qian Baoren and Long Jizhi. After that, the newspaper continued to publish newspapers and criticized the authorities for their crimes. Finally, the newspaper office was closed on July 7.

The Qing government entrusted lawyers to accuse Zhang Taiyan and others of "slandering the world and slandering the government" in mixed court. In the face of the trial, Zhang Taiyan said generously that the word’ Zai Tian Clown’ in the book violated the sacred words. I only know that the Qing emperor was Manchu and didn’t know the so-called sacred words. "

On May 21, 1904, the concession authorities and the Shanghai magistrate jointly tried the case and announced that Zhang Taiyan was sentenced to three years’ imprisonment and Zou Rong was sentenced to two years’ imprisonment. When Zhang Shizhao later recalled Su’s report, he said, "There is no taboo between his words. He denounced Zai Tian as a clown, which is more expensive than a relative and a thief. Only the publications in Tokyo, Hong Kong can do it, but in the mainland, he dared not or refused." This shows how strict the censorship of speech was in the Mainland at that time.

Since leaving the circle, the traffic of Xiaomi Automobile, as a new force in building cars, has been rising, and it has also broken 20,000 units with bicycles for two consecutive months. It is precisely because of the traffic blessing of the first explosion model that the rumored first Xiaomi SUV model has been receiving much attention. On the day of the announcement by the Ministry of Industry and Information Technology in December, Xiaomi’s second new car was officially announced, and all kinds of "Farami" imaginary maps on the Internet were overturned at the moment when they saw the official map.

Perhaps, because of the first young man’s "Bao Shi Mi", everyone thinks that it is not impossible for Xiaomi’s first SUV to pay tribute to Ferrari, and it is precisely because of the high expectations buried in the early days that many netizens saw Xiaomi YU7 at first sight, and there was a little bit of loss in their hearts.

Indeed, Xiaomi YU7 is not as amazing as Xiaomi SU7 when it was first launched. The main reason is that the appearance of Xiaomi YU7 is basically a copy and paste of the design language of Xiaomi SU7, and it is still a drop-shaped headlight group, with full muscle lines on the hood, which can identify the lever. Not surprisingly, the front enclosure of Xiaomi YU7 is still equipped with an active air intake grille.

On the side of the car body, Xiaomi YU7 adopts a slip-back posture. The biggest difference from Xiaomi SU7 is that Xiaomi YU7 uses a hidden door handle. Is it difficult to reduce wind resistance? It is worth mentioning that although Xiaomi Yuqi is an SUV model, its body is equipped with aerodynamic design in many places. It can be seen that Xiaomi Yuqi has made a lot of efforts in appearance details in order to reduce energy consumption. Perhaps this is the aerodynamic bridge design between Xiaomi Yuqi and Ferrari. "Heart and soul". From the existing application information, we can see that Xiaomi YU7 provides a variety of wheel hub styles, and offers 19, 20 and 21 inches to choose from, and bright yellow Brembo brake calipers are indispensable. In addition, Xiaomi YU7 is also equipped with lidar, and the high-order intelligent driving has not fallen.

In the rear part, Xiaomi YU7 continues to use the same circular taillight as Xiaomi SU7, with the spoiler above the rear windshield, the electric lifting tail and the rear surrounding diffuser. The sense of movement is rendered in place, which is really more distinctive than most SUV models on the market. If Xiaomi YU7 can be equipped with a circular exhaust layout, it will be even more fried.

Body size, length, width and height of Xiaomi YU7 are 4999/1996/1600mm respectively, and the wheelbase is 3000 mm.. Compared with millet SU7 (length, width and height are 4997/1963/1455mm and wheelbase is 3000mm), millet YU7 only has a large variation in width and height. The interior has not been announced yet, but its layout is not much different from that of Xiaomi SU7. However, judging from the positioning of Xiaomi YU7, the riding experience of Xiaomi YU7 should be better than that of Xiaomi SU7, which pays attention to the sense of control. Maybe you can see the zero-gravity seat. Let’s look forward to it!

In terms of power, Xiaomi YU7 will be equipped with a dual-motor system. The maximum power of the front motor is 220kW, the maximum power of the rear motor is 288kW, and the maximum speed is 253 km/h. The battery will be equipped, and the specific cruising range has not been announced yet. As for the most popular driving force at the moment, it is expected that it will not appear for the time being.

Love comment

With the growing sales of Xiaomi SU7, it shows that Xiaomi has gradually gained market recognition, while the first SUV model has chosen a conservative route, and it is also expected that such operations will occur. Although there is not much bright spot in the appearance of Xiaomi YU7, the "expanded" Xiaomi YU7 is not simply copied and pasted, but focuses on reducing energy consumption. Moreover, according to the previous control and adjustment of Xiaomi Automobile and the performance of the highest speed of 253km/h, I believe that Xiaomi YU7, which pays attention to comfort, will not disappoint people. Looking back at the positioning of Xiaomi YU7, it is obvious that Xiaomi YU7 is running. According to the consistent routine of Xiaomi Automobile, the pricing of Xiaomi YU7 should be lower than that of Model Y, which starts at 249,900 yuan. In this regard, do you think Xiaomi Yuqi is still the next explosion? Welcome to leave a message in the comment area.

I drive a Camry (parameter picture) twin engine, and there are three shortcomings that are unacceptable, and it is really expensive to change the battery. I advise people who want to buy a hybrid car to think twice, otherwise it will be too late to regret it!

The automobile industry is experiencing a great change that has never happened in a hundred years, and it has become an inevitable trend to develop new energy vehicles.

Plug-in hybrid vehicles and pure electric vehicles are the main models in the future, while hybrid electric vehicles will be eliminated in the future!

This is the real reason why Corolla twin-engine, Camry twin-engine, CR-V and other hybrid vehicles can’t be on the "green card"!

However, at present, Toyota and Honda-based hybrid electric vehicles have achieved high sales, and many consumers are waiting to see and want to buy a hybrid electric vehicle.

So is the current hybrid car worth buying? What are the shortcomings?

Next, I will analyze the advantages and disadvantages of the hybrid car and how much it costs to replace the battery, hoping to give some valuable information to readers who want to buy a hybrid car.

What’s the difference between Toyota THS, Honda i-MMD and BYD DM-i? Did DM-i learn from Honda i-MMD?

We want to know whether the hybrid car is worth buying. First, we need to understand the working principle of the hybrid car, so as to understand the advantages and disadvantages of the hybrid car!

At present, Toyota THS and Honda i-MMD hybrid systems are the main hybrid vehicles. Although both of them are hybrid systems, their working principles are obviously different.

The working principles of Honda i-MMD and BYD DM-i are more similar, so Honda CR-V has two hybrid models, one is a hybrid electric vehicle, and the other is a plug-in hybrid vehicle.

Honda’s i-MMD oil-electric hybrid uses clutches to realize three driving modes.

The first pure electric modeWhen the engine does not work, the clutch of the power separation device is disconnected, the vehicle is directly driven by the motor, and the power battery provides the power source. At this time, the working principle is the same as that of a pure electric vehicle.

The second hybrid modeThe vehicle is still directly driven by the driving motor, and the engine works normally. At this time, the power clutch is disconnected, and the engine is only responsible for driving the motor to generate electricity, and does not directly participate in the driving.

At this time, the working mode is more like an extended-range electric vehicle, and the driving principle is the same as that of an extended-range electric vehicle in Li ONE, so the engine always runs at the highest efficiency and the fuel economy is very high.

The third engine direct drive modeThe engine is working, the power clutch is closed, and the driver controls the power output of the engine through the throttle. At this time, the working mode is the same as that of the fuel vehicle.

When the vehicle needs to overtake and speed up, the motor intervenes to drive, and the auxiliary engine drives the vehicle together. At this time, the vehicle has the strongest power.

The above three driving modes are basically consistent with the working principle of BYD DM-i. Some people think that DM-I borrowed the working principle of i-MMD, but as early as 2008, BYD introduced F3DM, which is the world’s first mass-produced dual-mode vehicle.

The working principle of BYD F3DM is not the same as that of the familiar Tang DM, but the same as that of the Song Plus DM-I. As for why it was not accepted by the market at that time, the main reason was that the engine carried by the F3DM was too poor.

The DM engine is equipped with a 1.0L three-cylinder engine, and its power output is not strong. In the hybrid mode, the power output is insufficient, which makes it impossible to play the advantages of the hybrid mode, so it was eliminated by the market.

In 2012, Honda released the i-MMD hybrid technology, and in 2013, it officially launched the production model, so it was not DM-i that borrowed from i-MMD.

Toyota THS has developed into THS II, which is much better than the previous generation and can be divided into two driving modes.

The first pure electric modeThe engine does not participate in the work and will not start, and the vehicle is driven entirely by the motor, which is the first difference from Honda i-MMD.

However, the pure electric mode of Toyota THS II has a disadvantage, taking Camry twin engines as an example.

Because the battery is only 1.3kwh, it can only be turned on when the power is sufficient, and the pure electric mode can only travel about 2KM, and the speed cannot exceed 50km/h, otherwise it will directly exit the pure electric mode.

It can be said that the pure electric mode of Camry dual-engine is relatively small, but the application scenarios are still relatively rich. For example, the pure electric mode can be enabled when moving cars in short distances, congested roads and queuing, which can avoid the engine idling for a long time.

On the one hand, it can avoid carbon deposition caused by long idle speed of the engine, on the other hand, the engine stops working to achieve the purpose of saving fuel.

The second hybrid mode, due to the working principle of Toyota THS II, is divided into two working states in hybrid mode.

The first working stateDuring normal driving, when the Toyota THS II exits the pure electric mode, the vehicle directly enters the hybrid mode, and the engine and motor drive the vehicle at the same time.

When the power output by the engine is greater than the driving force required by the vehicle, the engine will drive the generator to charge the battery.

The second working stateWhen speeding up overtaking, long-distance climbing and high-speed driving, the engine and motor will still drive the vehicle together, but the engine will use all the power to drive the vehicle and the generator will stop charging the battery.

The power battery also uses all the electricity for motor-driven vehicles, at which time the vehicle has the strongest power. Because Toyota THS II has no engine direct drive mode, this is the second difference from Honda i-MMD.

The first disadvantage, the characteristics of the hybrid working mode of oil and electricity, can’t be green, can’t be exempted from purchase tax, and the price is expensive, saving fuel but not saving money.

Whether Toyota’s THS II or Honda’s i-MMD, the energy for driving vehicles in pure electric mode still comes from fuel.

The cruising range of pure electricity is too short, and the motor is only an auxiliary function. The main driving mode is the engine.

Therefore, hybrid electric vehicles are not new energy vehicles, so they can’t get a green license, and they can’t enjoy the same exemption from purchase tax as plug-in hybrid vehicles.

Take Camry twin engines as an example. The starting price is 219,800 yuan, 40,000 yuan more than the fuel version of the entry-level Camry, and 20,000 yuan more than the fuel version of the Camry with the same configuration.

Imagine that the hybrid of oil and electricity does save fuel, but can it save fuel and money?

I’ll work out an account for you.

With the same configuration, the fuel consumption of the fuel version Camry is 5.7L； per 100 kilometers; The average fuel consumption of Camry twin engines is 4.1L per 100 kilometers.

• The dual-engine version saves 1.6L fuel consumption per 100 kilometers compared with the fuel version.
• No.95 gasoline is 7.51 yuan per liter.

Camry dual engine saves 12.016 yuan in fuel per 100 kilometers compared with the fuel version of Camry. Driving 100 kilometers can save fuel in 12 yuan. Is it worth buying a hybrid car?

If the extra 20,000 yuan for purchasing the dual-engine version is used as fuel money,

20 thousand yuan can buy 95 # gasoline 150200L L.

The dual-engine version saves 1.6L fuel consumption per 100 kilometers compared with the fuel version.

Then Camry twin engines need to travel 93,875 kilometers to save the extra 20,000 yuan.

However, more than 90,000 kilometers, in addition to operating vehicles, basically few car owners can save fuel and money.

If a private car travels 10,000 kilometers a year, it will take at least 9 years to save money on fuel return, so it is said that hybrid electric vehicles save fuel but not money.

Moreover, it is not the same as plug-in hybrid cars. Although plug-in hybrid cars are also fuel-efficient and do not save money, they can get a green card without purchase tax, which is suitable for car owners.

Therefore, the first unacceptable disadvantage of the hybrid electric vehicle is that it saves fuel and does not save money. With the working principle similar to that of the plug-in hybrid vehicle, it can’t be a green card!

The second disadvantage is that the engine is noisy.

The engine noise of hybrid electric vehicle is very loud, which I felt on Camry twin engines, but it is not disturbing all the time, mainly in two cases, the engine noise will be very obvious.

In the first case, the cold car starts.

When the battery is fed, the cold car starts again. At this time, the engine noise of Camry dual-engine will be very loud, and the engine noise can be felt in the whole underground garage. Sometimes it will be caused by traffic jams for a long time, which may be because the engine water temperature is low.

When the car is cold, the engine can’t reach the best state, but it needs to drive the motor to charge the battery, which leads to the noise of the engine increasing under the combination of these two States.

In the second case, when driving at high speed, the battery is strongly charged.

When the Camry twin engines are driving on the highway, the engine cannot directly drive the vehicle due to the hybrid characteristics of Toyota THS II, so the battery must be charged.

Because the vehicle runs at high speed, it requires high power. At this time, it is necessary to drive both the vehicle and the motor to charge the battery, which leads to insufficient engine power.

In order to complete these two working conditions at the same time, the engine can only increase the speed, because the self-priming engine can only obtain the best power output at high speed.

Therefore, when driving at high speed and the battery is strongly charged, the noise of the engine will become very large. If it is sensitive to noise, it will affect the driving experience.

The third disadvantage is that the battery capacity is too small, and the power connection will shake.

As mentioned earlier, the battery capacity of the Camry twin-engine is only 1.3kwh, so it can only travel at a low speed of about 2km, which means that the Camry twin-engine basically travels in hybrid mode.

However, when switching from pure electricity to hybrid mode, sometimes there will be jitter, sometimes very small, sometimes very large, and sometimes not at all.

This is related to the small battery capacity. When the battery feed is switched to the hybrid mode, the engine needs to drive the vehicle and the engine to generate electricity at the same time, so the engine power is insufficient, and the power connection jitter appears.

If the power is switched when the battery is fully charged, and the engine and the battery drive the vehicle at the same time, there will be no jitter.

Therefore, the jitter caused by too small a battery may be unavoidable. This shortcoming is actually good, but it is somewhat unacceptable for car owners who pursue perfection.

Replacing the battery is expensive, so drive carefully.

Toyota and Honda’s hybrid electric system can be said to be very mature, and they all adopt "shallow charging and shallow discharging" to extend the battery life.

As long as the battery capacity of Toyota THS system is lower than 60%, it will stop discharging directly, while that of Honda is 55%.

This has both advantages and disadvantages. The advantage is that the battery can always be kept at more than 50%, which can increase the number of battery cycles and prolong the battery life.

The disadvantage is that the battery capacity of the hybrid electric vehicle is very small, and it is lightly charged and discharged every time, which makes it impossible to switch the power output mode for a long distance, which may cause the body to shake.

Due to the protection methods adopted by Toyota and Honda for the power battery, under normal use, the battery will basically not decay to the point where it cannot be used normally or be damaged.

Moreover, Toyota guarantees the battery for 8 years or 200,000 kilometers, and Honda guarantees the battery for 10 years or 200,000 kilometers, so the owner does not have to worry about battery damage, and it is expensive to replace the battery.

However, if the battery is damaged by the owner, it is not cheap to replace a battery.

Theoretically, taking the Camry dual engine as an example, the battery capacity is only 1.3kwh. At present, the power battery is 1,300 yuan /kwh, and it is 1,300 yuan to change a battery, plus the working hours are up to 3,000 yuan.

In fact, according to the maintenance cost of replacing the power battery exposed by the owner, it is obvious that it cost 23,848 yuan to replace the battery.

Therefore, it is not cheap to replace the battery in a hybrid electric vehicle, but as long as you drive normally, you basically don’t have to worry about the cost of replacing the battery.

Advantages of hybrid gasoline-electric vehicle

Although I mentioned the disadvantages of hybrid electric vehicles, its advantages cannot be ignored.

1. Whether driving at high speed or in traffic jam, the fuel consumption is relatively stable, and the fuel consumption per 100 kilometers is basically about 5L, which is very suitable for car owners who often run long distances.

2. A tank of oil can run more than 1000 kilometers, so you don’t have to worry about mileage anxiety, and you don’t have to refuel frequently. In today’s fast pace of life, the time saved is money.

3. No matter under any working conditions, the power of the hybrid electric vehicle can come at any time, the power output is better than that of the fuel vehicle, and the power ride comfort and driving experience are incomparable to that of the fuel vehicle.

The extra cost of buying a hybrid electric car may not be able to save fuel and money, but the driving experience is great!

Write it at the end

Hybrid cars are worth buying, but not for everyone.

If you don’t use cars frequently, don’t run at high speed, and just commute to work, then a fuel car is enough.

If there are requirements for power, endurance and long-distance driving, then a hybrid electric vehicle is worth buying.

If you buy a hybrid electric car just to save money, then I advise you to think twice. Actually, it doesn’t save money. If you buy it rashly, it’s too late to regret it!

　　BEIJING, Beijing, December 22 (Zheng Jiawei) "Programming education is not to cultivate code farmers, but to cultivate students’ programming ability, and the most important thing is the process, which trains the way of thinking in the process of presenting logical thinking and finally solves practical problems in life." Dr. Yu Xiaoya, a professor at Beijing Institute of Education, said.

　　On the 21st, an observation activity and seminar on innovative classroom teaching of programming education in primary and secondary schools was held in Beijing. On the day of the meeting, teachers from all over the country gathered in the No.1 Primary School of Exhibition Road, Xicheng District, Beijing to observe the programming demonstration class provided by the No.1 Primary School of Exhibition Road, and discuss how to further cultivate students’ innovative thinking and practical ability after the course.

　　In the demonstration class, under the guidance of the teacher, the students in Grade 5 of the primary school used the programming cat tool to complete the animation production and the programming of the voice-activated lighting system, respectively. Many students said that they liked the hands-on operation in class very much and wanted to continue to play programming when they got home.

　　Guan Jiying, one of the two teachers who participated in the demonstration class, was responsible for teaching the programming of acoustic control lighting system. After the students finished the basic programming of acoustic control system, she further inspired the students to think about the practical application of acoustic control system, and finally guided the students to program the noise indicator system. When the surrounding voices were normal, the green light turned on, but when the voice was too loud, it turned red.

　　On July 8th, this year, the State Council issued the Development Plan of the New Generation of Artificial Intelligence, specifically proposing to implement the national intelligence education project, set artificial intelligence related courses in primary and secondary schools, gradually promote programming education, and encourage social forces to participate in the development and promotion of educational programming teaching software and games.

　　Zhu Hui, a researcher in Xicheng District, Beijing, said in an interview with Zhongxin.com that although the State Council issued a notice to add programming to the classrooms of primary and secondary schools, schools still need to choose appropriate programming tools in the actual operation process to make this requirement a reality.

　　According to Zhu Hui, programming education in Xicheng District has always been in the forefront of Beijing. From the first computer elective course in 1982 to the graphical programming language education with "programming cats", it has always focused on cultivating students’ procedural thinking and solving problems in real life.

　　A few days ago, the National People’s Congress Standing Committee (NPCSC) voted to completely ban illegal wildlife trade, get rid of the bad habit of eating wild animals, and effectively protect people’s lives, health and safety.

　　This decision is obviously closely related to the COVID-19 epidemic. So, what is the relationship between Covid-19 transmission and wildlife?

　　Let’s sort out the recent related scientific research results.

　　On February 24th, a piece of news caught people’s attention. The National People’s Congress Standing Committee (NPCSC) voted to pass a decision on completely banning illegal wildlife trade, getting rid of the bad habit of eating wild animals, and effectively protecting people’s lives, health and safety. A system of completely prohibiting the consumption of wild animals has been established. In violation of the existing laws and regulations, the punishment should be aggravated on the basis of the existing laws.

　　At present, under the situation that the whole country is playing chess and fighting against the COVID-19 epidemic, this decision is obviously closely related to the COVID-19 epidemic.

　　Bats may be the source of Covid-19.

　　Humans are no strangers to infectious diseases caused by coronavirus. The SARS coronavirus, which was prevalent in winter of 2002 to 2003, was confirmed to have originated from the natural host bat, passed through the intermediate host civet cats and then passed on to humans. MERS coronavirus discovered in 2012, namely Middle East respiratory syndrome coronavirus, was also considered to have originated from natural host bats and spread to humans through intermediate host camels.

　　Since the winter of 2019, novel coronavirus, whose infection scale far exceeds that of SARS and MERS, has been transmitted to human beings through what channels?

　　Because of the lessons of SARS and MERS, scientists naturally set their sights on bats first.

　　Shi Zhengli’s team from Wuhan Institute of Virology, Chinese Academy of Sciences published a paper in the form of preprint on bioRxiv website on January 23rd, and this paper was published online by the top academic journal Nature on February 3rd. In this paper, the research team compared the novel coronavirus genome extracted from patients with severe pneumonia with the coronavirus gene sequence carried by a bat in the early laboratory, and found that the whole genome sequence of RaTG13 coronavirus in this bat was as consistent as 96.2% with novel coronavirus infected by human.

　　This means that the natural host of Wuhan novel coronavirus is probably a bat!

　　RaTG13, a virus closely related to bats, is the ancestral virus of novel coronavirus, which is derived from a coronavirus of China Jutoubat, which was discovered by Shi Zhengli’s team when sampling in Yunnan.

　　Moreover, novel coronavirus’s infection with humans needs to go through the pathway of ACE2 receptor. The similarity between the ACE2 receptor of China Jutous Bat and the human ACE2 receptor is consistent with the potential intermediate host other than other non-human primates. This shows that novel coronavirus, from bat virus to human infection, may not need an intermediate host, but can directly infect humans from bats.

　　In China, the hibernation period of bats is from December to late February. At first, people thought that the virus began to spread at the end of December last year, so the possibility of direct transmission from bats to people was ruled out. However, with more and more retrospective case studies, people found that novel coronavirus had been passed on to people as early as last November. Then, it is possible to pass it directly from bats to people.

　　For example, in a paper published on the website of ChinaXiv on February 21st, researchers from Xishuangbanna Tropical Botanical Garden of China Academy of Sciences, South China Agricultural University and Beijing Brain Center excavated the source and transmission path of Covid-19 from genome data. The researchers collected 93 genome data of novel coronavirus from 12 countries in 4 continents. According to the genome calculation, Covid-19 has undergone two large-scale expansions, one of which was on December 8, 2019.

　　It is inferred that the virus began to spread from person to person at least in early December 2019 or even in late November. Obviously, the virus should be transmitted from animals to people before human transmission. In other words, Covid-19 will be transmitted from animal hosts to humans no later than November 2019.

　　Pangolin may be the intermediate host of Covid-19.

　　At present, the academic circles still accept the conclusion that Covid-19 originated from bats and bats are its natural hosts, but there is no conclusion as to whether Covid-19 directly passed from bats to humans.

　　Many of the early cases of Covid-19 were related to the South China Seafood Market in Wuhan, Hubei Province, where there were a lot of wildlife transactions. China Center for Disease Control and Prevention also reported that Covid-19 was detected in environmental samples obtained from this market. More than 10 years ago, a similar wildlife market has been proved to be related to the SARS outbreak in 2002-2003, so wild animals probably participated in the spread of Covid-19.

　　At present, many scientists are looking for intermediate hosts in Covid-19, among which pangolin is the most likely candidate animal for intermediate hosts in Covid-19.

　　Among the papers speculating that pangolin is an intermediate host, two papers are most worthy of attention at present.

　　On February 18th, Professor Guan Yi from the School of Medicine of Hong Kong University and Hu Yanling from Guangxi Medical University published a paper on bioRxiv, a pre-printed website of medical papers, saying that genome sequencing showed that coronavirus was found in Malay pangolins smuggled from Southeast Asia intercepted in Guangdong and Guangxi, and the similarity with Covid-19 was between 85.5% and 92.4%. The paper holds that the coronavirus pedigrees found in pangolin are very similar to those in Covid-19, and pangolin should be regarded as a possible intermediate host in Covid-19, and it should be forbidden to be sold in fresh markets to prevent the spread of zoonotic diseases.

　　It was South China Agricultural University that first proposed that Malayan pangolin was an intermediate host. On February 7th, South China Agricultural University announced this research result: Pangolin is a potential intermediate host in novel coronavirus. Researchers from South China Agricultural University, such as Shen Yongyi and Xiao Lihua, joined hands with Yang Ruifu, a researcher from the Academy of Military Medicine, and Chen Wu, a senior veterinarian from the Scientific Research Department of Guangzhou Zoo to tackle the problem. By analyzing the virus genome, they found that the virus strain isolated from pangolin was 99% similar to the virus strain currently infecting people, and the receptor binding domains of the two viruses were similar.

　　In the preprint of the paper published later, they claimed that pangolin coronavirus was highly related to Covid-19. In particular, the receptor binding domain of pangolin coronavirus S protein is almost the same as that of novel coronavirus in 2019, with only one amino acid difference.

　　The paper also puts forward important serological evidence, that is, the coronavirus antibody in pangolin’s peripheral blood can bind to Covid-19. Moreover, pangolin infected by virus shows pathological changes and clinical symptoms similar to those of human beings.

　　In this paper, the author also boldly infers that the comparison of existing genomes shows that novel coronavirus in 2019 may have originated from the recombination of pangolin coronavirus and bat coronavirus RaTG13.

　　The paper also said that if the wildlife trade is not effectively controlled, the newly discovered coronavirus may pose a continuous threat to public health.

　　Wild animals are virus reservoirs.

　　What changes did novel coronavirus go through before it was brought into Wuhan and broke out in the crowd?

　　According to the evidence that scientists are looking for now, it may have originated from bats and spread directly to humans; It may also originate from the recombination of bat coronavirus and pangolin coronavirus, and then spread to humans through pangolin.

　　But to be sure, this is not the first or the last virus transmitted from animals to humans. In just 20 years of this century, there have been three kinds of new coronavirus epidemics: SARS, MERS and novel coronavirus.

　　In fact, it is not only the SARS virus and Covid-19 that have caused great losses to our country that are closely related to wildlife. Wild animals are the natural hosts of many serious emerging diseases. Statistics show that at present, 70% of new infectious diseases come from wild animals.

　　For example, natural reservoir, a bat that attracts much attention, has more than 100 kinds of viruses. They can carry many deadly viruses that are very dangerous to people, such as Ebola virus, Marburg virus, SARS virus, MERS coronavirus, Hendra virus and Nipah virus, but they don’t get sick themselves. This may be related to bat’s unique "all-weather" immune system.

　　"We all live on the virus planet, and wild animals are the reservoirs of these viruses." Nathan Wolf, Ph.D. in immunology and infectious diseases at Harvard University, once said this in "The Virus Attacks: How to Deal with the Outbreak of the Next Epidemic".

　　In our country, people have the backward concept of "eat what you eat to make up for what you eat", and there is also the mentality of eating novelty. All kinds of game are served on the table, and all kinds of wildlife trade are repeatedly banned. These invisible dangerous viruses will mutate in various trading links of wild animals and break through the species barrier — — From animal infectious diseases to human infectious diseases. With the increase of population density, the continuous progress of urbanization and the continuous improvement of the convenience of the national transportation network, once the relevant epidemic situation occurs, it will easily turn into a huge disaster and cause huge losses.

　　Although the relevant law enforcement agencies in China have made a series of achievements in prohibiting illegal hunting, breeding, transportation, trading and smuggling of wild animals, due to the lack of ideas and weak market supervision, there are still chaos such as openly selling wild animals and their products, and illegal hunting, transportation and trading of wild animals for the purpose of eating. However, the current Criminal Law and the Wildlife Protection Law lack or are insufficient in provisions on the consumption of wild animals, and the scope and intensity of sanctions are very limited.

　　We expect that, after the passage of the relevant bills banning the consumption of wild animals in an all-round way and severely cracking down on illegal wildlife trading, we will strengthen law enforcement in order to safeguard public health safety and ecological safety legally and in compliance, and prevent the recurrence of epidemics such as SARS and novel coronavirus.

　　Respecting nature, adapting to nature and protecting nature, and making "protecting wild animals and guarding against cross-species transmission of viruses" become the idea of each of us, which is the lesson we should learn from this novel coronavirus epidemic.
