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.

Have you ever been swimming in a pond, stream, or lake and had a leech(水蛭) stick on you? You probably shouted and tried to force it away as fast as you could. But leeches aren’t really sick, and sometimes they can save lives.
In ancient Egypt and later medieval(中世纪) Europe, doctors put leeches on patients. They believed that the spineless wormlike living things can cure all kinds of illnesses by sucking(吮吸) a patient’s blood. In Europe and in the United States, millions of leeches were used throughout the 1800s. Doctors used leeches to treat a number of illnesses, from obesity to headaches. People soon learned that leeches could not cure most diseases and were not a good treatment for patients. However in 1985, a Harvard University doctor changed people’s thinking once again. He was trying to reattach(重新接上) a patient’s ear, which had been cut off. He had trouble reconnecting the veins because the patient’s blood kept clotting(凝). He used a leech to draw out the blood and saved the ear.
Since then, leeches have often been used in surgery where body parts are reattached. During surgery, a leech is placed on the area where the surgeon does not want the blood to pool and clot. Then the leech produces a thing that keeps the veins(静脉) open and stops the blood from clotting. The leech sucks up excess blood, allowing fresh blood to flow, which helps the patient get well.
Some people are scared to death at the thought of having a blood sucking thing attached to them. But why not welcome a leech if it can save your life?
1.What is the passage mostly about?
A.Patient’s interest in leeches.
B.How and where leeches live.
C.The medical uses of leeches.
D.Leeches in ancient medicine.
2.When were leeches first used?
A.In medieval Europe.
B.In ancient Egypt.
C.In 1985 by a Harvard University doctor.
D.In the 1800s in Europe and in the United States.
3.When a leech is placed on a patient, which one happens first?
A.The leech produces a thing.
B.The patient’s veins open.
C.The patient’s blood flow faster
D.The leech sucks up excess blood.
4.Why did a doctor in 1985 decide to try using leeches?
A.He needed a way to close the wound.
B.He wanted to change people’s thought.
C.He believed in the mystery of nature.
D.He needed to keep blood from clotting
