【题目】 The novel coronavirus pneumonia (NCP) has already made a number of people sick. Where did the virus come from? Scientists say it probably came from bats.

Bats can carry and transmit (传播) more than 60 viruses that can infect(传染) humans, Live Science noted. They include the world's deadliest viruses, such as Ebola and HIV. Because of their strong immune systems (免疫系统), bats are able to host these viruses and not get sick. At the same time, the viruses keep developing inside the bats to create new variants (变体). These variants can then infect new hosts, such as other wild animals.

Pangolins (穿山甲), for example, might be an intermediate host (中间宿主) for NCP, according to a recent study by Chinese scientists. This means that bats might have given the virus to pangolins, with pangolins then spreading it to humans.

Wild animals like snakes, hedgehogs (刺猬) and bamboo rats also carry different virus. But since they live in the wild, there should be little chance for humans to come into contact with them and get infected - unless the animals are eaten or used to make animal products. When people hunt, buy and eat wild animals, they can introduce viruses to the rest of the population.

But this doesn't mean that we should kill wild animals. Each species has a role in the ecosystem (生态系统) and all of them are important in keeping a natural ecological balance. The lesson we can learn from disease outbreaks is to protect animals and to live in harmony with them instead of hunting, killing, or eating them.

1Why can bats host many viruses without getting sick?

A.Because these viruses are not deadly.B.Because they have strong immune systems.

C.Because the viruses are kept in balance.D.Because they can spread the viruses to other animals.

2According to a recent study, humans might get infected with COVID-19 from _________.

A.pangolinsB.snakesC.hedgehogsD.bamboo rats

3What does the underlined word "harmony" in the last paragraph probably mean?

A.隔离B.伤害C.和谐D.集中

4According to the story, what lesson should humans learn?

A.Research more about wild animals.B.Exercise regularly to stay healthy.

C.Stop keeping animals as pets.D.Don't buy or eat wild animals.

【答案】

2A

3C

4D

【解析】

这篇短文主要讲述了NCP冠状病毒,它来自一些病毒宿主的野生动物:如穿山甲,蝙蝠等等,人类应该与他们和平相处。

1

细节理解题。根据第二段中“Because of their strong immune systems (免疫系统), bats are able to host these viruses and not get sick.”可知,由于蝙蝠具有强大的免疫系统,所以蝙蝠能成为这些病毒的宿主而不会生病。故选B

2

细节理解题。根据第三段中“Pangolins (穿山甲), for example, might be an intermediate host (中间宿主) for NCP, according to a recent study by Chinese scientists.”可知,根据中国科学家最近的一项研究表明,穿山甲可能是人类感染新冠病毒的中间宿主。故选A

3

词句猜测题。分析前半句“The lesson we can learn from disease outbreaks is to protect animals”可知,从疾病爆发中我们可以学到的教训是尊重和保护动物。所以推测此处是“与它们和谐相处”。此处harmony的意思是“和平,和谐”。故选C

4

推理判断题。A:多研究野生动物;B:经常锻炼以保持健康;C:不要把动物当宠物养;D:不要买或吃野生动物。根据第四段中“When people hunt, buy and eat wild animals, they can introduce viruses to the rest of the population.”当人们捕猎、购买和食用野生动物时,他们会把病毒传染给其他人;及第五段中“The lesson we can learn from disease outbreaks is to protect animals and to live in harmony with them instead of hunting, killing, or eating them.”可知,从疾病爆发中我们可以学到的教训是尊重和保护动物,与它们和谐相处,而不是猎杀或吃掉它们。可以推断我们应该避免接触和吃野生动物,不要购买和吃野生动物。故选D

【题目】 William Blake described the eyes as the “windows of the soul.” Our eyes are the windows through which we see the world around us. Either way, there’s no question that we place great value on our eyes and our eyesight. Surveys have shown that of the five senses, sight is the one that people fear losing the most.

Thinking about the important function of our eyes, we’d give them the best care possible, but sometimes we get too busy or forget to do a few simple things that can keep our eyes healthy.

Protecting your eyes starts with the food on your plate. Remember when you were a kid and your mom told you that carrots would improve your eyesight. Well, she might be right. Proper food will keep your eyes strong and healthy.

Give up your daily habits that could seriously injure your eyes. Always wear sunglasses in a sunny day to protect your eyes from ultraviolet ray(紫外线). Rest your eyes every 20 minutes from the computer screen by looking 20 feet away for 20 seconds. At least every 2 hours, get up and take a 15-minute break when working at a computer.

Make sure your eyes do not get injured in the first place. You should try to prevent eye injuries whether you’re playing sports or doing housework. You should also know when to wear safety glasses and what kinds will work best for you.

Last but not least, get your eyes examined regularly. Eye exams can help find some eye diseases. It’s important to find these diseases early on, when they’re easier to treat.
