More than 100 people have now died from the new coronavirus (冠状病毒)-COVID-19. The number of people infected in mainland China increased sharply in one day-from 2, 700 Monday to more than 4,500 Tuesday. The increase comes even as China takes strong measures to stop the spread of the disease.

Coronaviruses are a large family of viruses that cause disease in mammals (哺乳动物)　 and birds. Coronaviruses can cause illnesses from the common cold to much more serious illnesses like Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). Experts still do not have a clear picture of the severity of the new coronavirus.

Officials are calling the disease a "novel" or new coronavirus because it has not been found before in humans. The new virus is thought to have spread to humans from wild animals sold at a market in Wuhan, in central China's Hubei Province. But it is now spreading between people. Chinese officials say the disease is able to spread from one person to another even before any actual signs appear. This makes it especially hard to stop.

Signs of the disease among infected patients have included fever, cough, shortness of breath and general breathing difficulties. In more serious cases, the virus can cause pneumonia（肺炎）. Some people report few or no signs, while others have gotten very sick or even died. Experts say that signs of the virus may appear between two and fourteen days after being near someone who is infected.

There is no special treatment for the new coronavirus. However, many of its effects are treatable, as long as a patient is in fair health. Because the virus is so new among humans, there is no available vaccine(疫苗) to protect against the disease. But the World Health Organization advises people to avoid close contact with anyone showing signs of a breathing sickness, such as coughing or sneezing. It also says people should wash their hands often and use safe food practices.

A novel coronavirus （新冠状病毒）, a cousin of the SARS virus, has infected （感染）more than 40, 000people since the outbreak （爆发） began in Huanan Seafood Market, Wuhan, China, in December. At first, we knew little about this virus. With more researches going on, we get to learn more about it.

Coronaviruses are a large group of viruses that are common among animals. In rare cases,　 they are what scientists call zoonotic （人畜共患病）,　 meaning they can be transmitted(传播) from animals to humans, according to the US Centers for Disease Control and Prevention.It is believed that the novel coronavirus spreads from human contact with animals.Bats are widely believed to be carriers of the latest strain of the disease.

Chinese researchers said on Friday that the endangered pangolin （穿山甲） may be the intermediate（媒介） host between bats and humans.

The viruses can make people sick, usually with a mild（轻度） to moderate（中度） upper respiratory tract illness（上呼吸道疾病）, similar to a common cold, including a runny nose, cough, sore throat, possibly a headache and maybe a fever, which can last for a couple of days. For those with a weakened immune（免疫的）system, the elderly and the very young,　 there's a chance the virus could cause deadly diseases.

What's horrible about this virus is that once a human is infected, he/she becomes a carrier of the virus and spreads it to more people by coughing, sneezing or even handshaking.The virus can also be transmitted by touching something an infected person has touched and then touching your mouth, nose or eyes. Doctors and nurses may also catch the disease when taking care of the patients, so they are required to wear strict protective clothes.

To fight against the disease, as individuals（个人，个体）, we should strictly follow the requirements of the government to stay at home and help to prevent the spread of the disease. In terms of the （ 就……而言）government, a strong health care system can surely help decrease the risk of health attack and lessen the impact of the disease.

1.Where did the outbreak begin?

2.What animal does the novel coronavirus come from according to the researchers?

3.What symptoms （症状） may people have when they are affected?

The novel coronavirus pneumonia (NCP) has already made a number of people sick. Where did the virus come from? Scientists say it probably came from bats.

Bats can carry and transmit (传播) more than 60 viruses that can infect（传染） humans, Live Science noted. They include the world's deadliest viruses, such as Ebola and HIV. Because of 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 different virus. But since they live in the wild, there should be little chance 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 ecosystem (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 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 they have strong immune systems.

C.Because the viruses are kept in balance. D.Because they can spread the viruses to other animals.

2.According to a recent study, humans might get infected with COVID-19 from _________.

A.pangolins B.snakes C.hedgehogs D.bamboo rats

3.What does the underlined word "harmony" in the last paragraph probably mean?

A.隔离 B.伤害 C.和谐 D.集中

4.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.
