Experts hope an experimental drug can be as effective against the novel coronavirus in people as it has been on cells in a controlled lab environment.

The US drug, remdesivir (瑞德西韦), began clinical trials（临床试验）on patients in Wuhan, Hubei province on Thursday. Other medications, including chloroquine, arbidol and darunavir have also recently been found capable of arresting viral growth in lab cells, but like remdesivir, they require more clinical trials to confirm their safety and potency on humans.

The Phase III trials for remdesivir have been approved by China’s National Medical Products Administration and is conducted by the China-Japan Friendship Hospital in Beijing and the Chinese Academy of　 Medical Sciences on patients at the Wuhan Jinyintan Hospital.

“A total of 761 patients will participate in two trials-one trial to assess the drugs' potency on 308 cases with mild or moderate infection, and the other on 453 severely infected patients”, Cao Bin, head of the clinical trial and vice-president of the friendship hospital, said on Wednesday.

Cao said studies have shown remdesivir is effective in inhibiting the growth of the novel coronavirus in vitro(在生物体外), meaning the procedure was done on cells in a controlled environment outside of a living organism, typically in a petri dish or test tube.

But the drug has yet to show convincing clinical evidence that it can translate its positive in vitro results into actual human patients. So, it will require strict clinical testing, Cao said.

A 35-year-old patient from the United States infected with the virus was reported seeing noticeable improvement with no obvious side effects after taking the drug, according to the New England Journal of Medicine.

Gilead Sciences, the maker of remdesivir, said in a recent statement that it has been working with government agencies on the novel coronavirus response efforts.

However, the company stressed that remdesivir is an experimental medicine that has only been used in a handful of patients, “so we do not have an appropriately full understanding of the effect of this drug ”.

1.Why does the US drug, remdesivir, began clinical trials?

A.To replace the traditional medicine.

B.To confirm their safety and potency on humans.

C.To show whether remdesivir is effective in inhibiting the growth of the novel coronavirus in vitro.

D.To see how it takes effect.

2.What is true according to the passage?

A.After taking the drug, a 35-year-old patient was infected with the virus.

B.Doctors had seen noticeable success treating a 35-year-old patient infected with the virus.

C.Remdesivir can cure those who are infected with the novel coronavirus.

D.Chinese Hospital does The Phase III trials independently.

3.What’s the author's attitude towards the clinical trial of remdesivir?

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.danger B.peace C.pain D.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.
