Question

【题目】 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 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 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】

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】推理判断。根据文中“Due to their strong immune systems (免疫系统)，bats are able to host these viruses and not get sick.” 由于蝙蝠具有强大的免疫系统，所以它们能够宿主这些病毒而不会生病。故选C。

【2】词句猜测。danger危险；.peace和平 pain痛苦； surprise吃惊。根据上文“The lesson we can learn from disease outbreaks is to respect and protect animals” 从疾病爆发中我们可以学到的教训是尊重和保护动物。可知，此处是“与它们和谐相处”。此处harmony的意思是“和平，和谐”。故选B。

【3】主旨大意。Research more about wild animals多研究野生动物； Exercise regularly to stay healthy. 经常锻炼以保持健康；Stop keeping animals as pets. 不要把动物当宠物养； Don’t buy or eat wild animals. 不要买或吃野生动物。根据文中“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“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.” 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。
