Question

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

Bats can carry and transmit more than 60 viruses that can infect humans， Live Science noted. They include the world’ s deadliest viruses，such as Ebola and HIV. Due to 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 various viruses. But since they live in the wild，there should be few chances 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 eco-system (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 respect and 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 the viruses are kept in balance.

C.Because they have strong immune systems.

D.Because they can spread the viruses to other animals.

【2】The underlined word“harmony”in the last paragraph probably means .

A.dangerB.peaceC.painD.surprise

【3】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】C

【2】B

【3】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】推理判斷。根據(jù)文中“Due to their strong immune systems (免疫系統(tǒng))，bats are able to host these viruses and not get sick.” 由于蝙蝠具有強大的免疫系統(tǒng)，所以它們能夠宿主這些病毒而不會生病。故選C。

【2】詞句猜測。danger危險；.peace和平 pain痛苦； surprise吃驚。根據(jù)上文“The lesson we can learn from disease outbreaks is to respect and protect animals” 從疾病爆發(fā)中我們可以學到的教訓是尊重和保護動物�？芍�，此處是“與它們和諧相處”。此處harmony的意思是“和平，和諧”。故選B。

【3】主旨大意。Research more about wild animals多研究野生動物； Exercise regularly to stay healthy. 經常鍛煉以保持健康；Stop keeping animals as pets. 不要把動物當寵物養(yǎng)； Don’t buy or eat wild animals. 不要買或吃野生動物。根據(jù)文中“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“The lesson we can learn from disease outbreaks is to respect and protect animals and to live in harmony with them instead of hunting，killing，or eating them.” 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。可以推斷我們應該避免接觸和吃野生動物，不要購買和吃野生動物。故選D。
