Following the outbreak of the novel coronavirus pneumonia (NCP), also named COVID -19 by WHO, there is a general fear of the unknown virus as its full effects remain to be seen. Fever, coughing, sore throat, difficulty breathing – the NCP’s symptoms are similar to the common cold or the flu, but it’s potentially more dangerous.

Viruses could be deadly, like HIV and Ebola. 1. How can they cause so much trouble?

Viruses are non-living organisms approximately one-millionth of an inch long. Unlike human cells or bacteria, they can’t reproduce on their own. Instead, they invade the cells of living organisms to reproduce, spread and take over.

Viruses can infect every living thing – from plants and animals down to the smallest bacteria. 2. Sometimes a virus can cause a disease so serious that it is fatal. Other viral infections bring about no noticeable reaction.

Viruses lie around our environment all of the time, waiting for a host cell to come along. They can enter our bodies by the nose, mouth, eyes or breaks in the skin. 3. For example, HIV, which causes AIDS, attacks the T-cells of the immune system.

But the basic question is, where did viruses first come from? 4. “Tracing the origins of viruses is difficult,” Ed Rybicki, a virologist at the University of Cape Town in South Africa, told Scientific American, “because viruses don’t leave fossils (化石) and because of the tricks they use to make copies of themselves within the cells they’ve invaded.”

However, there are three main theories to explain the origin of viruses. First, viruses started as independent organisms, then became parasites (寄生者). Second, viruses evolved from pieces of DNA or RNA that “escaped” from larger organisms. Third, viruses co-evolved with their host cells, which means they existed alongside these cells.

5. The technology and evidence we have today cannot be used to test these theories and identify the most plausible explanation. Continuing studies may provide us with clearer answers.

A.But what are viruses?

B.For the time being, these are only theories.

C.Once inside, they try to find a host cell to infect.

D.The answer may be even less satisfactory than it now appears.

E.Until now, no clear explanation for their origin exists.

F.Experts are concerned about the bad effect that it had on people’s health.

G.For this reason, they always have the potential to be dangerous to human life.

Following the outbreak of the novel coronavirus pneumonia (NCP), also named COVID—19 by WHO, there is a general fear of the unknown virus as its full effects remain to be seen. Fever, coughing, sore throat, difficulty breathing—the NCP’s symptoms (症状) are similar to the common cold or the flu, but it’s potentially more dangerous.

Viruses could be deadly, like HIV and Ebola (埃博拉). But what are viruses? How can they cause so much trouble?

Viruses are non-living organisms (有机体) approximately one-millionth of an inch long. Unlike human cells or bacteria, they can’t reproduce on their own. Instead, they invade (入侵) the cells of living organisms to reproduce, spread and take over.

Viruses can infect every living thing — from plants and animals down to the smallest bacteria. For this reason, they always have the potential to be dangerous to human life. Sometimes a virus can cause a disease so serious that it is fatal. Other viral infections trigger (引起) no noticeable reaction.

Viruses lie around our environment all of the time, waiting for a host cell to come along. They can enter our bodies by the nose, mouth, eyes or breaks in the skin. Once inside, they try to find a host cell to infect. For example, HIV, which causes AIDS, attacks the T-cells of the immune system.

However, there are three main hypotheses (假说) to explain the origin of viruses. First, viruses started as independent organisms, then became parasites (寄生者). Second, viruses evolved from pieces of DNA or RNA that “escaped” from larger organisms. Third, viruses co-evolved with their host cells, which means they existed alongside these cells.

For the time being, these are only theories. The technology and evidence we have today cannot be used to test these theories and identify the most reasonable explanation. Continuing studies may provide us with clearer answers. Or future studies may reveal that the answer is even murkier (含糊不清的) than it now appears.

Rob Braddick, 48, who owns Braddick’s Holiday Park in Westward Ho, Devon, in the southwest of England, has filled the toy grabber machines in his amusement park with two of the country’s most sought-after cleaning products.

Customers could previously try their hand at grabbing “Frozen 2” or “Peter Rabbit” toys from the machines, but no more. “They got removed this morning,” Braddick said of the toys, replacing them with toilet roll and hand sanitizer (洗手液). Visitors can now pay 50p for three goes on the toilet roll grabber, or ?1 a go for Carex, which Braddick described as the “Rolls- Royce of hand sanitizers.”

Braddick said that his decision was born of a desire to make people feel less stressed in uncertain times. “It’s a bit of light relief with everything that’s going on,” he said. “Hopefully it will raise a smile, which I think everybody needs.”

Around the world, travel plans have been severely affected, and tens of millions of people remain at home as part of global efforts to fight against coronavirus. Supermarkets have seen shortages of toilet paper and hand sanitizer as anxious consumers stockpile the products.

Braddick said the family business, which has been running since 1932, has received more than a dozen calls from potential customers who say they don’t want to travel abroad for their holidays and would rather stay in the UK. As for his own measures against coronavirus, Braddick said staff have been told to wash their hands every half hour, which is particularly important for those handling money.
