【題目】 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 (瑞德西韋), began clinical trials(臨床試驗)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(在生物體外), 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 ”.

1Why 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.

2What 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.

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

A.Negative.B.Critical.C.Positive.D.Gloomy.

4Where is this text most likely from?

A.A diary.B.A guidebook.C.A novel.D.A magazine.

【解析】

本文講述了針對新冠肺炎,瑞德西韋等幾種藥物進入臨床試驗。

1細(xì)節(jié)理解題。根據(jù)“they require more clinical trials to confirm their safety and potency on humans”可知,瑞德西韋這種藥開始臨床試驗,是為了確定藥物的安全性和有效性。故選B。

2細(xì)節(jié)理解題。After taking the drug, a 35-year-old patient was infected with the virus. 一個35歲的病人在服用了這種藥物后,感染了這種病毒。根據(jù)“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.”可知,一名35歲的美國病人服用該藥后,病情有明顯改善,無明顯副作用,而不是服用藥物后感染了病毒,所以A項表述錯誤。Doctors had seen noticeable success treating a 35-year-old patient infected with the virus.醫(yī)生們在治愈一位35歲的病人時取得顯著成功。根據(jù)“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.”可知,一名35歲的美國病人服用該藥后,病情有明顯改善,無明顯副作用。這名美國病人在服用瑞德西韋之后,療效顯著。所以B項表述正確。Remdesivir can cure those who are infected with the novel coronavirus.瑞德西韋可以治愈那些被新型冠狀病毒感染的人。根據(jù)“the company stressed that remdesivir is an experimental medicine that has only been used in a handful of patients”可知,瑞德西韋是一種實驗性藥物,只在少數(shù)病人中使用過,并不能證明這種藥可以治愈新冠肺炎感染的病人,所以C項表述錯誤。Chinese Hospital does The Phase III trials independently.中國醫(yī)院獨立進行三期臨床試驗。根據(jù)“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.”可知,瑞德西韋的三期臨床試驗已獲得中國國家醫(yī)療產(chǎn)品管理局的批準(zhǔn),由北京中日友好醫(yī)院和中國醫(yī)學(xué)科學(xué)院對武漢金銀潭醫(yī)院的患者進行,所以三期臨床試驗是中國醫(yī)院獨立進行,但是瑞德西韋是來自于美國的藥物,同時在美國也進行了三期臨床試驗。所以D項表述錯誤。故選B

3觀點態(tài)度題。根據(jù)“sExperts 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.”可知,由于瑞德西韋藥物在實驗室環(huán)境中取得良好的效果,因此現(xiàn)在投入臨床試驗,希望能獲得一樣好的效果。所以此處作者的態(tài)度是積極的。故選C。

4推理判斷題。根據(jù)“The US drug, remdesivir (瑞德西韋), began clinical trials(臨床試驗)on patients in Wuhan, Hubei province on Thursday.”并結(jié)合全文可知,文中主要是講瑞德西韋等幾種藥物進入臨床試驗,所以文章最有可能來源于醫(yī)學(xué)雜志。故選D。

【題目】 Later this year, Beijing will start the country’s first driverless(無人駕駛 ) subway trains. The Yanfang Line-connecting part of Fangshan district center-will be the first to try out driverless technology.

According to the experts(專家) in public transportation, the new trains will make the underground railway system(系統(tǒng)) better. They will have an upgraded(升級的)operating system. They will reach 80km per hour and carry more than 1,200 passengers.

The development of driverless technology is opening up in other areas of transport(交通工具). Driverless cars have been a dream for many people. And in the past few years, big car companies, including Volkswagen and Toyota, have made lots of studies while they are competing with other companies, such as Google.

But with not racks(軌道) to run on, how will driverless cars be safe? This technology is made up of many sensors(傳感器) including radar and GPS. This gives the car an exact position in the world, as well as what’s around it. It also allows the car to see moving objects(目標(biāo)), like other cars and people.

Pilot-free planes have also become a hot technology topic. Yet while these new kinds of technology are seen as better and safer, they do have problems. They cannot work at all without the help of computers. Just like humans, computers make mistakes-although less often. And like much of technology, it makes many workers lose their jobs. What will happen to the future bus drivers and pilots?

1Will Beijing start the country’s first driverless subway trains?

2How many passengers will the driverless subway train carry?

3What did the big companies do about the driverless technology?

4Why will driverless cars be safe?

5What does the writer mainly tell us in the last paragraph?

"I'm glad you like it, "Andy said.

"I do. And I want to spend more time with you. I always love the father-son time. I spent a lot with your grandfather when I was g8up. "
