The novel coronavirus pneumonias (COVID-1) outbreak in China was caused by a new coronavinus that we have never seen before. Some doctors found that several patients infected COVID-19 had been to the Huanan Seafood Market in Wuhan. All kinds of wild animals were on sale in the market. Some scientists found that the virus might come from bats and was then spread to humans from pangolins(穿山甲). According to Live Science, bats can carry and spread more than 60 viruses that can infect humans, such as Ebola and SARS. Other wild animals like snakes are also hosts of many viruses.

Why are bats probably the source of so many viruses? Here are several reasons as follows.

1. Bats tend to live in dark and wet places where there are many kinds of viruses.

2. Bats always live in groups. Therefore, the viruses can have larger "playgrounds" to evolve and become more powerful.

3. Bats are mammals(哺乳动物), just like humans. Our similar genes make it easier for us to become infected with the same viruses.

4. When bats fly, their body temperature can reach as high as 40℃. This high temperature can kill weak viruses, but stronger ones will survive and continue to evolve.

5. Bats have special immune(免疫的) systems that allow them to live with viruses without getting sick.

6. Since they can fly, bats can spread viruses farther and more easily than other animals. Although wild animals carry many diseases, it doesn’t mean that we should regard them as evil. Each has a role in the ecosystem(生态系统) and all of them are important for keeping a good ecological balance. The lesson we should learn from virus outbreaks is to respect and protect animals and to live in harmony with them, instead of hunting, killing, or eating them.

26. From the passage, some doctors found several patients infected COVID-19 had been to_____.

A．a seafood market

B．a station

C．a school

D．a hospital

A．humans

B．bats

28. The underlined word "evolve" probably means_____in Chinese in this passage.

A．加大

B．阻碍

C．进化

D．减少

29. According to the passage, which of the following is true?

A．Bats are mammals, not like humans.

B．High body temperature of bats can kill strong viruses.

C．The virus Ebola came form bats.

D．Wild animals carry many diseases, so we should regard them as evil.

30. The best title of this passage is______.

A．From Bats to Our Bodies	B．A Terrible Virus
