Question

【題目】 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 (傳播) more than 60 viruses that can infect（傳染） humans, Live Science noted. They include the world's deadliest viruses, such as Ebola and HIV. Because of their strong immune systems (免疫系統(tǒng)), 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 (變體). These variants can then infect new hosts, such as other wild animals.

Pangolins (穿山甲), for example, might be an intermediate host (中間宿主) 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 (生態(tài)系統(tǒng)) 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.

【1】Why 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.

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

A.pangolinsB.snakesC.hedgehogsD.bamboo rats

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

A.隔離B.傷害C.和諧D.集中

【4】According 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.

Answer 1

【答案】

【1】B

【2】A

【3】C

【4】D

【解析】

這篇短文主要講述了NCP冠狀病毒，它來自一些病毒宿主的野生動物：如穿山甲，蝙蝠等等，人類應該與他們和平相處。

【1】

細節(jié)理解題。根據(jù)第二段中“Because of their strong immune systems (免疫系統(tǒng)), bats are able to host these viruses and not get sick.”可知，由于蝙蝠具有強大的免疫系統(tǒng)，所以蝙蝠能成為這些病毒的宿主而不會生病。故選B。

【2】

細節(jié)理解題。根據(jù)第三段中“Pangolins (穿山甲), for example, might be an intermediate host (中間宿主) for NCP, according to a recent study by Chinese scientists.”可知，根據(jù)中國科學家最近的一項研究表明，穿山甲可能是人類感染新冠病毒的中間宿主。故選A。

【3】

詞句猜測題。分析前半句“The lesson we can learn from disease outbreaks is to protect animals”可知，從疾病爆發(fā)中我們可以學到的教訓是尊重和保護動物。所以推測此處是“與它們和諧相處”。此處harmony的意思是“和平，和諧”。故選C。

【4】

推理判斷題。A：多研究野生動物；B：經(jīng)常鍛煉以保持健康；C：不要把動物當寵物養(yǎng)；D：不要買或吃野生動物。根據(jù)第四段中“When people hunt, buy and eat wild animals, they can introduce viruses to the rest of the population.”當人們捕獵、購買和食用野生動物時，他們會把病毒傳染給其他人；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，從疾病爆發(fā)中我們可以學到的教訓是尊重和保護動物，與它們和諧相處，而不是獵殺或吃掉它們�？梢酝茢辔覀儜�該避免接觸和吃野生動物，不要購買和吃野生動物。故選D。
