十、阅读理解
A
It’s commonly known that greenhouse gases like carbon dioxide (CO2) causes global warming. The whole world has made great efforts to improve the situation. Among them, the trees planted in China are playing an important role.
A report published in Nature shows that CO2 absorption (吸收) in two new forest areas in China is more than we thought. The two areas are located in China’s southwestern and northeastern provinces. They make up over 35 percent of China’s carbon sinks. Carbon sinks are natural systems that absorb and store CO2 from the air. The main natural carbon sinks are trees and other plants.
According to Paul Palmer, these provinces have been working on rapid forestation (造林) in large areas. Over the past 10 to 15 years, the forest areas have kept increasing by 400-4,400 square kilometers per year.
China is one of the world’s biggest countries of human-produced CO2, ________. In 1978, China began a national-level forestation project. Many trees have planted in the areas of northern China to act as windbreaks. For example, about one third of the Kubuqi Desert in Inner Mongolia is now covered with trees. In 2019, Alipay’s Ant Forest program planted 122 million trees and won the UN Champions of the Earth award for helping 500 million people live low-carbon lives.
China’s goal is to reach carbon neutrality by 2060. Carbon neutrality refers to removing as much CO2 as one puts into the air. If China’s goal is achieved, it will lower global warming by around 0.2 to 0.3 ℃ alone, according to Climate Action Tracker (CAT).
1. China’s carbon sinks are mainly located in the ________.
A. southeast and northeast B. southwest and northeast
C. southeast and northwest D. southwest and northwest
2. In Paragraph 3, Paul Palmer shows China’s achievement in forestation by ________.
A. using numbers B. asking questions C. giving examples D. making comparison
3. Which of the following can be put in the ________ in Paragraph 4
A. and it has caused serious environmental problems
B. so the government will take steps to stop air pollution
C. though most of Chinese people are living low-carbon lives
D. but our country has been working on reducing its climate influence
4. The passage mainly talks about ________.
A. what causes global warming B. what China does to lower global warming
C. why China produces so much CO2 D. how trees absorb and store CO2 from the air
B
Recycling is a way to take rubbish and turn it into new products. It’s helpful to our environment. There are a number of different recycling steps that allow materials to be used more than once.
All kinds of materials can be recycled. Some of the most common things in use today include recycling plastic, glass, metals and paper. Things made of these materials include soda cans, plastic milk boxes, newspapers, computers and cardboard boxes.
There are a number of advantages for recycling. These include: Landfills—Recycling materials means less rubbish and saves space in landfills. Resources—When we use materials again, this means we can take fewer resources from the earth. Pollution—in general, recycling materials can produce less pollution, helping to keep our environment clean.
Be sure to recycle everything you can in your house and school. There is almost a “recycle” rubbish can around. Be sure to drop your used aluminum cans and plastic bottles there. At home, be sure to put paper things like the newspapers, paper boxes, and homework pages into the recycle box.
Plastics are usually marked with an identification code that shows a recycling symbol and a number from 1 to 7. This shows that the type of chemicals, or materials, is used in making the plastic. Used paper can be recycled around seven times.
It is high time we set up a recycle station in every street, across the city and the country, so the cleaners can transport the rubbish conveniently. This is the only way out for handling rubbish without causing danger to the environment and our health. For ourselves, our children and our children’s children, let’s take action NOW!
1. From the first paragraph, we know that ________.
A. we can make more money from recycling
B. recycling is helpful to our environment
C. recycling is common and popular
D. there is too much rubbish around us
2. In paragraph 3, we know that recycling has many advantages including ________.
A. less rubbish B. more space
C. less pollution D. all the above
3. What kinds of materials are usually marked with an identification code
A. Paper. B. Plastics. C. Glass. D. Metals.
4. The underlined word “handling” in the last paragraph means ________ in Chinese.
A. 处理 B. 生产 C. 收购 D. 变卖
5. What does the writer mainly want to tell us
A. We should recycle everything in our daily life.
B. Many resources can be saved by recycling.
C. We should take action to recycle rubbish.
D. Recycle stations should be set up in the street.

A
It’s commonly known that greenhouse gases like carbon dioxide (CO2) causes global warming. The whole world has made great efforts to improve the situation. Among them, the trees planted in China are playing an important role.
A report published in Nature shows that CO2 absorption (吸收) in two new forest areas in China is more than we thought. The two areas are located in China’s southwestern and northeastern provinces. They make up over 35 percent of China’s carbon sinks. Carbon sinks are natural systems that absorb and store CO2 from the air. The main natural carbon sinks are trees and other plants.
According to Paul Palmer, these provinces have been working on rapid forestation (造林) in large areas. Over the past 10 to 15 years, the forest areas have kept increasing by 400-4,400 square kilometers per year.
China is one of the world’s biggest countries of human-produced CO2, ________. In 1978, China began a national-level forestation project. Many trees have planted in the areas of northern China to act as windbreaks. For example, about one third of the Kubuqi Desert in Inner Mongolia is now covered with trees. In 2019, Alipay’s Ant Forest program planted 122 million trees and won the UN Champions of the Earth award for helping 500 million people live low-carbon lives.
China’s goal is to reach carbon neutrality by 2060. Carbon neutrality refers to removing as much CO2 as one puts into the air. If China’s goal is achieved, it will lower global warming by around 0.2 to 0.3 ℃ alone, according to Climate Action Tracker (CAT).
1. China’s carbon sinks are mainly located in the ________.
A. southeast and northeast B. southwest and northeast
C. southeast and northwest D. southwest and northwest
2. In Paragraph 3, Paul Palmer shows China’s achievement in forestation by ________.
A. using numbers B. asking questions C. giving examples D. making comparison
3. Which of the following can be put in the ________ in Paragraph 4
A. and it has caused serious environmental problems
B. so the government will take steps to stop air pollution
C. though most of Chinese people are living low-carbon lives
D. but our country has been working on reducing its climate influence
4. The passage mainly talks about ________.
A. what causes global warming B. what China does to lower global warming
C. why China produces so much CO2 D. how trees absorb and store CO2 from the air
【答案】1. B 2. A 3. D 4. B

Recycling is a way to take rubbish and turn it into new products. It’s helpful to our environment. There are a number of different recycling steps that allow materials to be used more than once.
All kinds of materials can be recycled. Some of the most common things in use today include recycling plastic, glass, metals and paper. Things made of these materials include soda cans, plastic milk boxes, newspapers, computers and cardboard boxes.
There are a number of advantages for recycling. These include: Landfills—Recycling materials means less rubbish and saves space in landfills. Resources—When we use materials again, this means we can take fewer resources from the earth. Pollution—in general, recycling materials can produce less pollution, helping to keep our environment clean.
Be sure to recycle everything you can in your house and school. There is almost a “recycle” rubbish can around. Be sure to drop your used aluminum cans and plastic bottles there. At home, be sure to put paper things like the newspapers, paper boxes, and homework pages into the recycle box.
Plastics are usually marked with an identification code that shows a recycling symbol and a number from 1 to 7. This shows that the type of chemicals, or materials, is used in making the plastic. Used paper can be recycled around seven times.
It is high time we set up a recycle station in every street, across the city and the country, so the cleaners can transport the rubbish conveniently. This is the only way out for handling rubbish without causing danger to the environment and our health. For ourselves, our children and our children’s children, let’s take action NOW!
1. From the first paragraph, we know that ________.
A. we can make more money from recycling
B. recycling is helpful to our environment
C. recycling is common and popular
D. there is too much rubbish around us
2. In paragraph 3, we know that recycling has many advantages including ________.
A. less rubbish B. more space
C. less pollution D. all the above
3. What kinds of materials are usually marked with an identification code
A. Paper. B. Plastics. C. Glass. D. Metals.
4. The underlined word “handling” in the last paragraph means ________ in Chinese.
A. 处理 B. 生产 C. 收购 D. 变卖
5. What does the writer mainly want to tell us
A. We should recycle everything in our daily life.
B. Many resources can be saved by recycling.
C. We should take action to recycle rubbish.
D. Recycle stations should be set up in the street.
【答案】1. B 2. D 3. B 4. A 5. C
