The world’s glaciers are melting（融化）quickly. Scientists, from Nature studied 20 years of satellite data of the world’s 220,000 mountain glaciers, and found that since 2015, glaciers have last 298 billion metric tons of ice and snow per year. That is 31% more than 15 years ago, and enough ice melt to put Switzerland under 7.2 meter of water each year.
Scientist say the melting is caused by climate（气候）change. Almost all of the world’s glaciers are melting. Half of the world’s glacier melts in the United States and Canada. Some miller glaciers are totally lost. The melting “mirrors” the worldwide increase in temperature and is from the burning of coal, oil and gas.
Shrinking（缩小）glaciers are a problem for million is of people who use regular glacier melt for drinking water. Very fast melting can also cause floods（洪水）in places like India. But the biggest problem to the world is rising sea levels, Glaciers are responsible for 21% of sea level rise. Mark Serreze, director of the American National Snow and Ice Data Center（NSIDC）in Colorado, thinks that sea level rise is going to be a bigger and bigger problem, as we move through the 21st century.
Scientists said that it could take hundreds of years to regrow melted glaciers. Twila Moon studies glaciers at the NSIDC. “I’m not sure whether the glaciers can regrow even if the planet’s temperature is controlled. We must try to keep much ice possible and slow the speed of glacier melting.” she said.
1. According to the passage, glacier melting is caused by ________.
A. climate change B. water pollution C. sea level rise D. serious floods
2. ________ of the glacier melt around the world is in the United States and Canada.
A. 21% B. 31% C. 50% D. 80%
3. What is the main idea of paragraph 3
A. The world’s glaciers are melting quickly.
B. Some smaller glaciers are completely lost.
C. The world’s glacier melting causes some problems.
D. People need to find ways to deal with glacier meting.
4. We can guess that Twila Moon might be ________ about glacier regrowing.
A. excited B. surprised C. angry D. worried
5. The passage is probably from ________.
A. a sports newspaper B. a science magazine
C. a story book D. a travel guide
【答案】1. A 2. C 3. C 4. D 5. B
【解析】本文主要讲述了全球各地的冰川都在融化，分析了冰川融化的原因及会带来的问题。

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 Kurumi 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).
6. 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
7. In Paragraph 3, Paul Palmer shows China’s achievement in forestation by ________.
A. using numbers B. asking questions C. giving examples D. making comparison
8. 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
9. 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】6. B 7. A 8. D 9. B
【解析】文章主要讲了中国为减缓全球变暖所做的一切。
6. 细节理解题。根据“The two areas are located in China’s southwestern and northeastern provinces. They make up over 35 percent of China’s carbon sinks.”可知中国的碳汇主要位于西南和东北。故选B。
7. 细节理解题。根据“Over the past 10 to 15 years, the forest areas have kept increasing by 400-4,400 square kilometers per year.”可知在第三段，Paul Palmer通过列数字展示了中国在造林方面的成就。故选A。
8. 推理判断题。下文讲中国为二氧化碳的产生对其后造成的危害所做的努力，由此可知虽然是世界上人为产生二氧化碳最多的国家之一，但一直在努力改变，设空处用“but our country has been working on reducing its climate influence”表示“但我们国家一直在努力减少对气候的影响”。故选D。
9. 主旨大意题。通读全文可知文章主要讲了中国为减缓全球变暖所做的一切。故选B。
C、根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项。
Did you throw something away today 1. But where does our rubbish go
It doesn’t just sit in the rubbish bin. Every day, workers come to take the rubbish from our rubbish bins. They put it into a big truck and then the truck carry it to landfills. At the landfill, people sort(分类) the rubbish. They recycle some, burn some and bury(埋) some of it underground. 2. It means that less rubbish ends up in landfills. Landfills can also be bad for the environment.
So many Chinese cities encourage everyone to sort out their rubbish before throwing it away. Put the food in one bag. Put the plastic bottles in another. And throw them in the right rubbish bins. In this way, we can help save a lot of time, money and energy for all of society.
3. So they have higher recycling rates (比率). In Sweden, only 4 percent of household waste ends up in landfills every year. In Japan, people recycle nearly 50 percent of all rubbish.
There is still a lot to do when it comes to rubbish sorting in China. People in the country make about 300 million tons of rubbish every year. 4. The rest of it ends up in landfills. Most of it is unsorted. The good news is that many cities are trying different ways to make things better. Beijing will start a new program to improve rubbish sorting next year. If people sort out their rubbish, they’ll get WeChat bonus points. 5.
A. But they only recycle less than a quarter of the waste.
B. The answer for most people would be yes.
C. Most foreign countries do not have sorting systems.
D. The more rubbish gets recycled, the better.
E. Many foreign countries have good sorting systems.
F. Parents should educate kids to throw away less food.
G. They can exchange the bonus points for shopping cards!
【答案】本文主要介绍了对人们每天制造的垃圾的处理办法。BDEAG

The world’s glaciers are melting（融化）quickly. Scientists, from Nature studied 20 years of satellite data of the world’s 220,000 mountain glaciers, and found that since 2015, glaciers have last 298 billion metric tons of ice and snow per year. That is 31% more than 15 years ago, and enough ice melt to put Switzerland under 7.2 meter of water each year.
Scientist say the melting is caused by climate（气候）change. Almost all of the world’s glaciers are melting. Half of the world’s glacier melts in the United States and Canada. Some miller glaciers are totally lost. The melting “mirrors” the worldwide increase in temperature and is from the burning of coal, oil and gas.
Shrinking（缩小）glaciers are a problem for million is of people who use regular glacier melt for drinking water. Very fast melting can also cause floods（洪水）in places like India. But the biggest problem to the world is rising sea levels, Glaciers are responsible for 21% of sea level rise. Mark Serreze, director of the American National Snow and Ice Data Center（NSIDC）in Colorado, thinks that sea level rise is going to be a bigger and bigger problem, as we move through the 21st century.
Scientists said that it could take hundreds of years to regrow melted glaciers. Twila Moon studies glaciers at the NSIDC. “I’m not sure whether the glaciers can regrow even if the planet’s temperature is controlled. We must try to keep much ice possible and slow the speed of glacier melting.” she said.
1. According to the passage, glacier melting is caused by ________.
A. climate change B. water pollution C. sea level rise D. serious floods
2. ________ of the glacier melt around the world is in the United States and Canada.
A. 21% B. 31% C. 50% D. 80%
3. What is the main idea of paragraph 3
A. The world’s glaciers are melting quickly.
B. Some smaller glaciers are completely lost.
C. The world’s glacier melting causes some problems.
D. People need to find ways to deal with glacier meting.
4. We can guess that Twila Moon might be ________ about glacier regrowing.
A. excited B. surprised C. angry D. worried
5. The passage is probably from ________.
A. a sports newspaper B. a science magazine
C. a story book D. a travel guide

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 Kurumi 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).
6. 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
7. In Paragraph 3, Paul Palmer shows China’s achievement in forestation by ________.
A. using numbers B. asking questions C. giving examples D. making comparison
8. 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
9. 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
C、根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项。
Did you throw something away today 1. But where does our rubbish go
It doesn’t just sit in the rubbish bin. Every day, workers come to take the rubbish from our rubbish bins. They put it into a big truck and then the truck carry it to landfills. At the landfill, people sort(分类) the rubbish. They recycle some, burn some and bury(埋) some of it underground. 2. It means that less rubbish ends up in landfills. Landfills can also be bad for the environment.
So many Chinese cities encourage everyone to sort out their rubbish before throwing it away. Put the food in one bag. Put the plastic bottles in another. And throw them in the right rubbish bins. In this way, we can help save a lot of time, money and energy for all of society.
3. So they have higher recycling rates (比率). In Sweden, only 4 percent of household waste ends up in landfills every year. In Japan, people recycle nearly 50 percent of all rubbish.
There is still a lot to do when it comes to rubbish sorting in China. People in the country make about 300 million tons of rubbish every year. 4. The rest of it ends up in landfills. Most of it is unsorted. The good news is that many cities are trying different ways to make things better. Beijing will start a new program to improve rubbish sorting next year. If people sort out their rubbish, they’ll get WeChat bonus points. 5.
A. But they only recycle less than a quarter of the waste.
B. The answer for most people would be yes.
C. Most foreign countries do not have sorting systems.
D. The more rubbish gets recycled, the better.
E. Many foreign countries have good sorting systems.
F. Parents should educate kids to throw away less food.
G. They can exchange the bonus points for shopping cards!
