A

In a new report, infectious disease expert Jeffrey Shaman believes there were at least half a dozen stealth coronavirus cases to every one diagnosis at the start of the epidemic.

The explosive spread of coronavirus was likely caused by ‘stealth transmissions’— undiagnosed people with mild symptoms unwittingly spreading the disease, a new study claims. Infectious-disease expert Jeffrey Shaman believes the actual number of contaminated worldwide is far greater than reports, estimating a million people may have been infected.

The environmental health sciences professor at Columbia University who co-wrote the study published on Monday said social distancing is a must in order to combat seemingly healthy people spreading the virus. Despite only being half as infectious as the documented infections, these stealth cases resulted in at least two-thirds of documented infections, Professor Shaman and his colleagues said. Prof Shaman said this flip in the ratios meant about 60 percent of carriers were confirmed — but fast forward to now and new daily cases have significantly dropped from thousands to tens. The study says a “radical increase in the identification and isolation of currently undocumented infections would be needed to fully control” the novel coronavirus.

People in the UK, meanwhile, have been told to avoid pubs, clubs and restaurants and work from home wherever it's possible to slow the spread of coronavirus which has now claimed 55 lives in the UK. Prime Minister Boris Johnson said at a press conference yesterday urged everyone to “stop non-essential contact and to stop all non-essential travel”. The PM said London appeared to be “a few weeks ahead” of other areas and urged people in the capital to pay special attention to the measures — including home working — suggested by the Government. The UK death toll yesterday rose to 35 while there have now been 1,543 cases. Health Secretary Matt Hancock yesterday said that over-70s could be asked to self-isolate for four months.

Across the world more than 6,000 people have now died from the disease.

1. How many people at least potentially got infected when one was diagnosed, according to Jeffrey Shaman?

A. Twelve.

B. Six.

C. Seven.

D. Ten.

2. What’s the best way to prevent the spreading from undiagnosed people with mild symptoms?

A. Wearing medical masks.

B. Not going to work.

C. Keeping a social distance.

D. Sending these people to hospital.

3. How does Professor Shaman consider the current control of the novel coronavirus?

A. Cheerful.

B. Uncertain.

C. Depressing.

D. Impossible.

4. Which of the following is NOT the advice of UK government?

A. To work at home instead.

B. Not to go out for any dinner.

C. To cancel unnecessary travel.

D. To self-isolate for the aged.

【答案】1-4 BCAB

【解析】本文是一篇说明文，描述了英国新冠肺炎的现状，同时也把政府已经和即将采取的措施公布于众。

1. 细节理解题。根据第一段第一句话“In a new report, infectious disease expert Jeffrey Shaman believes there were at least half a dozen stealth coronavirus cases to every one diagnosis at the start of the epidemic”可知，每确诊一个就可能有6个染上病毒的，故选B。

2. 细节理解题。根据第三段第一句“The environmental health sciences professor at Columbia University who co-wrote the study published on Monday said social distancing is a must in order to combat seemingly healthy people spreading the virus.”可知，保持一定的社交距离是必须的手段。故选C。

3. 观点态度题。根据第三段第三句“Prof Shaman said this flip in the ratios meant about 60 per cent of carriers were confirmed — but fast forward to now and new daily cases have significantly dropped from thousands to tens.”可知，从现在开始，每日新增病例已从数千例大幅下降到数十例。由此推之，教授对目前新冠肺炎的控制情况还是觉得比较可喜的。故选A。

4. 细节理解题。根据倒数第二段“Prime Minister...urged everyone to “stop non-essential contact and to stop all non-essential travel”...the measures—including home working...over-70s could be asked to self-isolate for four months.”可知，A、C、D三项都是政府对民众的建议，只有B 项（绝不出去就餐）不合题意，文章中指出政府是说减少不必要的接触，并没有说绝对不出去，故选B。
