"Please don't travel to Wuhan unless it's absolutely necessary," Zhong Nanshan, a famous respiratory (呼吸科的) expert, reminded the public when the novel coronavirus first hit Wuhan. But despite the danger, he, an 84-year-old man, took the train to Wuhan to fight the disease.
Known as the hero who defeated SARS in 2003, Zhong's image and messages are flooding (遍布) social media. Many people say they "trust every word of Zhong". He has given Chinese people confidence in winning the battle.
A great doctor and honest scholar (学者)

After months of work, his treatment plan for SARS was adopted (采纳) by China and then the whole world, saving thousands of lives, People's Daily reported.
Zhong is also known for being an honest scholar. In 2003, when authorities (官方) said that the SARS virus was under control, he publicly refuted their statement. "It's not all under control," Zhong said in a later interview. His honesty won widespread praise from the Chinese public.
Back to the frontlines
Seventeen years later, Zhong is once again leading an expert team to study the novel coronavirus (新型冠状病毒). Although this new virus is known to be more dangerous to the elderly, Zhong doesn't seem worried about his own safety.
On Jan 18, he took a high-speed train from Guangzhou to Wuhan. Two days later, he became the first expert to make certain that the new virus can be spread between humans. On January 29, he and his colleagues spent over four hours online checking five patients who were in serious condition. The next day, he chose the treatment for those patients. Under his guidance, his team developed a rapid test kit (快速检测试剂盒) for the disease that can show results within 15 minutes.
As People's Daily wrote, "the 84-year-old Zhong Nanshan shows his professionalism as a scholar, courage as a soldier, and a sense of duty as the backbone (脊梁) of our nation."

Terrible weather events are harming the planet, and experts warn of even greater results to come. The sea ice loss and the Arctic ice melting (融化) caused by climate change have increased much in the last ten years. So they have pushed down the number of polar bears and seals while polar bears depend on sea ice for hunting seals.
According to the data from the WMO, temperatures on the Antarctica (南极洲) just hit 18.3℃, which is higher than the record of 17.59℃ in March, 2015. Moreover, temperatures in this area have warmed about 3℃ over the last 50 years. Although such temperatures might be considered pleasant for a picnic or a hiking trip, this is the Antarctica we are talking about. It is home to the most inhospitable environment on the planet because it is supposed to be an extremely cold place. In fact, the average temperature of the continent’s central area is -57℃.
Besides, many places are experiencing the extreme weather this summer. Australia is undergoing its worst drought (干旱) since the 1930s, leaving bushfires burning so long and causing many deaths. Meanwhile in Europe, crops in the northwest are suffering the driest weather in the past 80 years. Recently West Texas in America has also gone through its worst drought in more than 70 years, while floods have hit Eastern and Southern China.
“Climate change is bad for us human beings, which causes direct health problems. I’m afraid there will be more common events like the one that 30,000 to 50,000 persons died in Europe in 2003 due to the heat wave there,” Professor Schwartz said. “It will also cause more air pollution, diseases and lack of clean water and so on.”
31. What doesn’t bring down the number of polar bears according to this passage
A. Hunting. B. Climate change. C. The sea ice loss. D. The Arctic ice melting.
32. What can you get out of this passage
A. The Antarctica is pleasant for a hiking trip.
B. Extreme weather led to wildfires burning in Europe.
C. Climate change will cause air pollution and diseases.
D. The temperatures on the Antarctica hit the highest in March, 2015.
33. What does the underlined word “inhospitable" in Paragraph 2 probably mean
A. comfortable to live B. friendly to live C. unhealthy to live D. unfit to live
34. Which place didn’t experience drought this year
A Europe. B. Australia. C. America. D. China.
35. What is the main idea for this passage
A. The whole planet is drier and drier. B. The Antarctica is warmer and warmer.
C. Climate change is getting worse and worse. D. The number of polar bears is smaller and smaller.
【答案】31. A 32. C 33. D 34. D 35. C
【解析】这是一篇说明文。主要讲述了气候变化对世界各地以及人类造成的危害。
31细节理解题。根据“The sea ice loss and the Arctic ice melting (融化) caused by climate change have increased much in the last ten years. So they have pushed down the number of polar bears and seals while polar bears depend on sea ice for hunting seals.”可知，气候变化造成海上浮冰和北极冰川融化，而北极熊是靠海冰捕食海豹的，所以造成北极熊数量减少的原因不包括捕食，故选A。
32.细节理解题。根据最后一段“It will also cause more air pollution, diseases and lack of clean water and so on.”可知，气候变化将导致更多的空气污染，疾病和水的缺乏等等，故选C。
33.词义猜测题。comfortable to live舒适的生活；friendly to live友好的生活；unhealthy to live不健康的生活；unfit to live不适合生活。根据“ because it is supposed to be an extremely cold place”（因为它应该是一个非常寒冷的地方）可推断，inhospitable在这里的意思是：不适宜居住的，结合选项，故选D。
34.细节理解题。根据第三段全段可知，澳大利亚、欧洲以及美国的西德克萨斯州都遭受了严重的干旱，而中国的东部和南部遭受了洪水，故选D。
35.主旨大意题。本文主要讲的是气候变化对世界各地以及人类造成的危害，结合选项，故选C。

Everyone knows by now that plastic pollution is a huge problem for the environment. Beijing, for example, has dealt with this by banning (禁止) thin plastic bags, plastic tableware (餐具) and other plastic items in supermarkets, restaurants and hotels since May 1, according to CGTN.
But an even better solution might be on the way. Researchers at a French company called Carbios have discovered a bacterial enzyme (细菌酶) that can break down plastic. The enzyme, which was first found in compost (堆肥) leaves, turns plastic into chemical “building blocks” that can then be used to create new products, according to the Guardian.
The new enzyme was uncovered in research that was published last month in the journal Nature. Researchers studied over 100,000 microorganisms (微生物) to find one that could break down plastic quickly. The leaf compost enzyme was first discovered in 2012. Scientists changed its genes (基因), allowing it to break down 90 percent of one ton of plastic in less than 10 hours.
“It had been completely forgotten, but it turned out to be the best,” said Professor Alain Marty, chief science officer at Carbios.
The enzyme especially breaks down PET, a type of plastic that is most commonly used to produce plastic bottles and food packaging (包装). It is the fifth most common type of plastic that we use.
Carbios said it is working together with companies like Pepsi and Nestle – major consumers of plastic themselves – to develop their research and start using the enzyme on an industrial scale (范围), according to Forbes.
36. What do we know about the enzyme
A. It is a type of bacteria.
B. It can break down plastic quickly.
C. It is the fifth-most common type of bacteria.
D. It can break down PVC.
37. What is Paragraph 3 mainly about
A. Where the scientists found the new enzyme.
B. How the scientists changed the enzyme’s genes.
C. How the scientists found the new enzyme.
D. When the scientists found the new enzyme
38. What does Alain Marty mean in Paragraph 4
A. It was too late to find the new enzyme.
B. The new enzyme was forgotten by experts.
C. They forgot to change the enzyme’s genes.
D. Better late than never.
39. What can we infer from the last paragraph
A. Carbios will work together with companies that use a lot of plastic.
B. Carbios will keep looking for a more efficient enzyme.
C. Carbios will turn its focus toward production.
D. Carbios will search for more companies like Pepsi to work with.
40.The best title of the article is_______.
A. How to protect our environment.
B.A natural way to recycle plastic.
C. Why Beijing has banned plastic items in many public places.
A. How Carbios discovered a bacterial enzyme.
【答案】BCDCB
【解析】本文介绍一种能够分解塑料的酶，如果我们很好利用，可以解决塑料污染的问题。
36.B 细节理解题。从Researchers at a French company called Carbios have discovered a bacterial enzyme (细菌酶) that can break down plastic。法国一家名为Carbios的公司的研究人员发现了一种能分解塑料的细菌酶。可知答案选B。
37.C主旨大意题，这一段主要介绍，这种酶是如何发现的。故答案选C。
38.D 细节理解题。这句话表达“亡羊补牢，未为晚。”这种意思。故答案选D。
39.C 推理判断题。从文中可知这种酶将要大规模用于工业中，说明Carbios公司将注意力要转移到生产上，与使用的公司合作生产。
40.B 本文介绍一种能够分解塑料的酶，大规模生产，可以解决塑料污染的问题。所以B更合题意。

We study and collect data about our natural environment and the wildlife living in it. Is there anyone watching us the same way US author Danielle Palli looks at this in her sci-fi novel The Data Collectors.
In her novel, humans once lived on many planets, but are now endangered. They now live only on Earth. An alien species called the “Data Collectors” is trying to figure out what caused this situation. However, other species would rather see humans die off so that they can take Earth’s natural resources.
On Earth, there is a woman named Lucene Jones who is troubled by old memories and has a talent for knowing things that she couldn’t possibly know. Members of an evil alien species want to use her special talent to take over Earth. They take over the governing body of the galaxy (星系) by corrupting (使……腐败) the body’s officials and winning their trust to help find Jones.
Fortunately, Jones gets help from the Data Collectors. With the help of them and other humans, Jones defeats (战胜) the evil aliens.
The novel is an interesting tale where space opera meets magical realism. The battle at the center of the story deals with politics, conspiracies (阴谋) and corruption. Along the way, readers can think about how the story touches on subjects such as immigration

And most people are richer than before. So more and more people have cars. They send out harmful gases, some people throw rubbish everywhere.
To protect our environment. We have to take action now. first, factories must make the water clean before they put it into the rivers. Second, we had better take buses more often instead of cars. Last but not least, we should put rubbish into dustbins.

Plastic straws (吸管) are “having a hard time” in America. Seattle became the first large city in the US to ban (禁止) plastic straws. Starbucks also said they planned to 11 using straws by 2020. And more companies and governments also followed.
Plastic is 12 to the environment. Some say banning plastic straws is an important 13 towards saving our planet, but others think plastic-straw bans are inconvenient (不方便的), unnecessary, and unfair. Let's see what these two Americans said.
Josh Lee from Chicago, Illinois 14 his idea. “Plastic straws may help make drinking easy, but the long-term 15 are too high. When they are 16 , they pollute our land and sea. Sea animals sometimes mistake the plastic for food. They may 17 because of that. In my opinion, if one likes using straws, he can buy paper or steel (钢) straws to carry with him.”
Maria Suarez from Bellaire, Texas thought 18 . “Many people with disabilities (缺陷) depend on plastic straws to drink safely. Without plastic straws, people might use paper straws, 19 making paper products uses a lot of energy. Also, it creates air and water pollution. And paper can be used only once. Plastic can be reused and recycled. Finally, it is 20 to think that banning plastic straws will save the sea. Instead, we should teach people to leave rubbish in the right place so it doesn't end up on beaches or in waterways.”

In difficult times, there are always people who step up and bring people hope and confidence. One of them is Zhong Nanshan.
"Please don't travel to Wuhan unless it's absolutely necessary," Zhong Nanshan, a famous respiratory (呼吸科的) expert, reminded the public when the novel coronavirus first hit Wuhan. But despite the danger, he, an 84-year-old man, took the train to Wuhan to fight the disease.
Known as the hero who defeated SARS in 2003, Zhong's image and messages are flooding (遍布) social media. Many people say they "trust every word of Zhong". He has given Chinese people confidence in winning the battle.
A great doctor and honest scholar (学者)
Growing up in a family of doctors, Zhong lives by a simple motto (信条): save lives and always be honest. In 2003, when SARS hit China, he volunteered to treat patients and asked his colleagues (同事) to send their most serious patients to him. After months of work, his treatment plan for SARS was adopted (采纳) by China and then the whole world, saving thousands of lives, People's Daily reported.
Zhong is also known for being an honest scholar. In 2003, when authorities (官方) said that the SARS virus was under control, he publicly refuted their statement. "It's not all under control," Zhong said in a later interview. His honesty won widespread praise from the Chinese public.
Back to the frontlines
Seventeen years later, Zhong is once again leading an expert team to study the novel coronavirus (新型冠状病毒). Although this new virus is known to be more dangerous to the elderly, Zhong doesn't seem worried about his own safety.
On Jan 18, he took a high-speed train from Guangzhou to Wuhan. Two days later, he became the first expert to make certain that the new virus can be spread between humans. On January 29, he and his colleagues spent over four hours online checking five patients who were in serious condition. The next day, he chose the treatment for those patients. Under his guidance, his team developed a rapid test kit (快速检测试剂盒) for the disease that can show results within 15 minutes.
As People's Daily wrote, "the 84-year-old Zhong Nanshan shows his professionalism as a scholar, courage as a soldier, and a sense of duty as the backbone (脊梁) of our nation."
26. What can we know about Zhong Nanshan from the passage except

Terrible weather events are harming the planet, and experts warn of even greater results to come. The sea ice loss and the Arctic ice melting (融化) caused by climate change have increased much in the last ten years. So they have pushed down the number of polar bears and seals while polar bears depend on sea ice for hunting seals.
According to the data from the WMO, temperatures on the Antarctica (南极洲) just hit 18.3℃, which is higher than the record of 17.59℃ in March, 2015. Moreover, temperatures in this area have warmed about 3℃ over the last 50 years. Although such temperatures might be considered pleasant for a picnic or a hiking trip, this is the Antarctica we are talking about. It is home to the most inhospitable environment on the planet because it is supposed to be an extremely cold place. In fact, the average temperature of the continent’s central area is -57℃.
Besides, many places are experiencing the extreme weather this summer. Australia is undergoing its worst drought (干旱) since the 1930s, leaving bushfires burning so long and causing many deaths. Meanwhile in Europe, crops in the northwest are suffering the driest weather in the past 80 years. Recently West Texas in America has also gone through its worst drought in more than 70 years, while floods have hit Eastern and Southern China.
“Climate change is bad for us human beings, which causes direct health problems. I’m afraid there will be more common events like the one that 30,000 to 50,000 persons died in Europe in 2003 due to the heat wave there,” Professor Schwartz said. “It will also cause more air pollution, diseases and lack of clean water and so on.”
31. What doesn’t bring down the number of polar bears according to this passage
A. Hunting. B. Climate change. C. The sea ice loss. D. The Arctic ice melting.
32. What can you get out of this passage
A. The Antarctica is pleasant for a hiking trip.
B. Extreme weather led to wildfires burning in Europe.
C. Climate change will cause air pollution and diseases.
D. The temperatures on the Antarctica hit the highest in March, 2015.
33. What does the underlined word “inhospitable" in Paragraph 2 probably mean
A. comfortable to live B. friendly to live C. unhealthy to live D. unfit to live
34. Which place didn’t experience drought this year
A Europe. B. Australia. C. America. D. China.
35. What is the main idea for this passage
A. The whole planet is drier and drier. B. The Antarctica is warmer and warmer.
C. Climate change is getting worse and worse. D. The number of polar bears is smaller and smaller.
D
Everyone knows by now that plastic pollution is a huge problem for the environment. Beijing, for example, has dealt with this by banning (禁止) thin plastic bags, plastic tableware (餐具) and other plastic items in supermarkets, restaurants and hotels since May 1, according to CGTN.
But an even better solution might be on the way. Researchers at a French company called Carbios have discovered a bacterial enzyme (细菌酶) that can break down plastic. The enzyme, which was first found in compost (堆肥) leaves, turns plastic into chemical “building blocks” that can then be used to create new products, according to the Guardian.
The new enzyme was uncovered in research that was published last month in the journal Nature. Researchers studied over 100,000 microorganisms (微生物) to find one that could break down plastic quickly. The leaf compost enzyme was first discovered in 2012. Scientists changed its genes (基因), allowing it to break down 90 percent of one ton of plastic in less than 10 hours.
“It had been completely forgotten, but it turned out to be the best,” said Professor Alain Marty, chief science officer at Carbios.
The enzyme especially breaks down PET, a type of plastic that is most commonly used to produce plastic bottles and food packaging (包装). It is the fifth most common type of plastic that we use.
Carbios said it is working together with companies like Pepsi and Nestle – major consumers of plastic themselves – to develop their research and start using the enzyme on an industrial scale (范围), according to Forbes.
36. What do we know about the enzyme
A. It is a type of bacteria.
B. It can break down plastic quickly.
C. It is the fifth-most common type of bacteria.
D. It can break down PVC.
37. What is Paragraph 3 mainly about
A. Where the scientists found the new enzyme.
B. How the scientists changed the enzyme’s genes.
C. How the scientists found the new enzyme.
D. When the scientists found the new enzyme
38. What does Alain Marty mean in Paragraph 4
A. It was too late to find the new enzyme.
B. The new enzyme was forgotten by experts.
C. They forgot to change the enzyme’s genes.
D. Better late than never.
39. What can we infer from the last paragraph
A. Carbios will work together with companies that use a lot of plastic.
B. Carbios will keep looking for a more efficient enzyme.
C. Carbios will turn its focus toward production.
D. Carbios will search for more companies like Pepsi to work with.
40.The best title of the article is_______.
A. How to protect our environment.
B.A natural way to recycle plastic.
C. Why Beijing has banned plastic items in many public places.
A. How Carbios discovered a bacterial enzyme.
