China gets greener
President Xi Jinping said "clear waters and lush mountains are invaluable assets(绿水青山就是金山银山)". With the efforts of China's government and its people, the rate of forest coverage(森林覆盖率)in China has reached 22. 96%, compared to 5. 05% forty years ago, according to a recent report from the State Forestry and Grassland Administration (SFGA).
Over the past forty years, China planted billions of trees as part of its fight against expanding(延伸的)deserts, mostly in its north. Each year, people sow seedlings(播种)over an area nearly the size of Ireland, according to Nature.
In 1978, China began a nationwide tree-planting programme known as the Three North Shelterbelt Forest Programme, also known as "the Great Green Wall". It has helped to plant more than 66 billion trees across 13 provinces in the country's north to act as windbreaks(防风林), according to China Daily.
Since 2018, SFGA has made more efforts to build a greener country. Its purpose is to grow at least 6. 7 million hectares(公顷)of forest every year in the next 15 years. Besides planting more trees, China has tried to bring back grasslands. It has also used strict forest protection methods and banned(禁止)all commercial logging(商业伐木)since last August.
The high-speed growth of forests cannot happen without public participation(参与). For example, Ant Forest, an Alipay mobile payment app, plants real tees for users who get "green energy" by taking part in low-carbon(低碳)activities. Since 2016, it has helped to plant about 122 million trees in China's driest areas.
China was praised as "one of the most successful countries worldwide in greening the desert" by United Nations Environment Programme Executive Director Erik Solheim.

Enjoying the holiday
Do some housework, make an English video to introduce a Chinese custom, read aloud Home Letters by Fu Lei, run for an hour every day.
These things are part of the winter holiday homework of Ma Yan, an eighth-grader from Tianjin. During the first long holiday after the “double reduction” policy（双减政策）was introduced, Ma found herself doing more practice-based learning instead of always having her nose in workbooks（练习册）. “I felt more relaxed this holiday, since the homework is clearly much less and more enjoyable,” said Ma. With more free time, Ma said she could also develop new hobbies like skating and stargazing（天文观测）.
Like Ma, many junior high school students welcomed the changes brought by the policy. Liu Yang, 14, said she visited the Tianjin Science and Technology Museum, as part of her homework. “We did some experiments there. It’s more fun than memorizing things from books,” Liu said. Another big difference for Liu is that she doesn’t have tutoring classes（课外辅导班）anymore. “This gives me more time to play badminton and I gradually（逐渐）get healthier.”
Some students, however, feel anxious（焦虑的） about the changes. “I used to take many tutoring classes, but now I’ve lost their instruction（指导） and need to make progress on my own,” said ninth-grader Zhou Xiuwei from Nanjing, “I felt more stressed this holiday.”
The goal of the double reduction policy, according to Wang Jian, director of the education department at Shanghai Normal University（上海师范大学）is to let students learn more efficiently（有效地）and develop all-round abilities. “It’s challenging for students to be independent and self-directed（自主的）learners, but this will help them become more creative and find their true gifts,” Wang told XinminWeekly（新民周报）.
36. What didn’t the writer mention about Ma Yan’s winter holiday life

Do you think animals can see colors Scientists(科学家) think that many animals cannot see colors. The world is black and white to them. Scientists want to find out if dogs can see colors. When the scientists give the dogs food, they show them a certain(一定的) color every time. The dogs get ready to eat when they see this color. The scientists then show the dogs another color. Again the dogs get ready to eat.
Scientists also do some experiments on some monkeys. They find color are not all the same to monkeys. For example, scientists put food in a red box, and do this every day. Monkeys always go to the red box to get food. And scientists put food in a blue box, monkeys don’t go there to get food. They still go to the red one to look for food. In the same way, scientists find birds always get food in the box of a certain color.

You don’t have to be a scientist to solve big environmental problems. One foreign designer (设计师) is finding creative ways to make a change—and he’s inviting bikers to join him.
Daan Roosgaarde, 38, is a designer from Holland (荷兰). He uses creative ideas to improve city life. For his Smog (雾霾) Free Project, he designed a special tower that cleans air in Chinese parks. In Holland, he designed a shining bicycle path.
Now Daan and his team are working with engineers at a Chinese bike-sharing company to create a new product for public use. It’s an air-cleaning machine connected to a bicycle and is part of the Smog Free Project. In smoggy weather, the machine would breathe in the dirty air in front of the bike and blow out a stream of clean air toward the biker’s face.
It’s no secret that air pollution is a big problem for China. In winter, it’s common for thick clouds of haze (霾), caused largely by factory production, burning of coal and car emissions (排放物), to cover areas of China.
In 2016, only one-fourth of Chinese cities met the country’s air quality (质量) standards, according to a survey of 338 cities nationwide from the Ministry of Environmental Protection.
“Of course one tower and a few bikes won’t solve China’s air pollution problem,”Daan said. “But smog-free bikes are an exciting idea that will hopefully inspire communities to create greener cities.”
36. According to the writer, ________.
A air pollution is not a big problem in China
B. creative ideas may help improve city life
C. only scientists can solve big environmental problems
D. the survey of 338 cities nationwide was not necessary
37. The air-cleaning machines offer clean air to the biker by ________.
A. blowing out dirty air B. running fast with the bike
C. cleaning the air around the biker D. breathing in the dirty air and cleaning it
38. From the passage, we know that ________.
A. China’s haze in winter happens because of more than three causes
B. only smog-free bikes can go on the shining bicycle path
C. people who have creative ideas can get free bikes
D. Daan and his family spent all their time improving China’s air quality
39. Daan is inviting bikers to join him in order to ________.
A. help solve the air pollution problem B. make more Chinese friends
C. raise money for the tower D. test his new machine
40. What is the best title for the passage
A. Biking for Fresh Air B. Breathing In and Out
C. survey from the Government D. China’s Air Pollution Problem

What would the world be like if cars could drive themselves Imagine seeing an empty car passing by on its way to pick up its owner, or a car full of passengers who are reading, listening to music or even sleeping. But none of them is worried about the road ahead.
Well, all of these could be the future of driving. There are several companies, for example, Google, working on driverless cars. So far, no Google self-driven car has got a traffic ticket, but some of them have been in accident when other cars hit them.
These cars are now still in the testing stages（测试阶段）. If the tests are successful, these electric, self-driven cars could be put into use very soon. But how is it possible for a car to drive itself Cars already have many features（特征） allowing them to replace drivers during certain situations. Some features include cars being able to park themselves, or slow down when they notice other cars close by. They can also control the speed（速度）if there are dangerous conditions.
Scientists believe that with the help of wireless signals（无线信号）, cameras and GPS, it is possible to create a safe self-driven car very soon.
The cause of serious road accidents is usually careless drivers or dangerous conditions. The self-driven car may be able to stop this. However, some people do not like the idea. They think that technologies can also be mistakes.
36. The main purpose of the first paragraph is to ________.

You don’t have to be a scientist to solve big environmental problems. One foreign designer (设计师) is finding creative ways to make a change—and he’s inviting bikers to join him.
Daan Roosgaarde, 38, is a designer from Holland (荷兰). He uses creative ideas to improve city life. For his Smog (雾霾) Free Project, he designed a special tower that cleans air in Chinese parks. In Holland, he designed a shining bicycle path.
Now Daan and his team are working with engineers at a Chinese bike-sharing company to create a new product for public use. It’s an air-cleaning machine connected to a bicycle and is part of the Smog Free Project. In smoggy weather, the machine would breathe in the dirty air in front of the bike and blow out a stream of clean air toward the biker’s face.
It’s no secret that air pollution is a big problem for China. In winter, it’s common for thick clouds of haze (霾), caused largely by factory production, burning of coal and car emissions (排放物), to cover areas of China.
In 2016, only one-fourth of Chinese cities met the country’s air quality (质量) standards, according to a survey of 338 cities nationwide from the Ministry of Environmental Protection.
“Of course one tower and a few bikes won’t solve China’s air pollution problem,”Daan said. “But smog-free bikes are an exciting idea that will hopefully inspire communities to create greener cities.”
