【题目】 When we are born,we are given names that stay with us for our whole lives. Some names include good wishes and hopes from parents, while others may be unique and easy to remember.

1

According to International Committee on Taxonomy of Viruses, an organization responsible for naming new viruses,the task of naming a virus is no less important than naming a person.

When a disease breaks out, people focus on the public health response 2 But that may lead to many problems. The most obvious one is that different media organizations may use different names for the same virus in their reports. We are now in the internet era. 3 This means different names can take hold quickly and be hard to take back, which may confuse those who know little about the virus.

4 Over the past decade, some improper names have caused problems. In 2009, the “swine flu” was widely used before the official name, HINI virus, was announced. This led Egypt to kill all of its pigs. In 2015, MERS (Middle East Respiratory Syndrome)caused a backlash (强烈抵制)against the nations and people of this region. So in 2015, the World Health Organization (WHO) announced that the names of viruses should avoid being named after geographic locations, people, species or classes of animals and foods.

5 The new coronavirus we are suffering from was named “COV-ID-19” on Feb 11. In this name, “CO” means “corona”, “VI” stands for “virus” and “D” means “disease”. Next time you read about a virus you don't know, you may get some clues about it from its name.

A.But naming a virus is never easy.

B.The WHO followed these principles this time .

C.News can spread to every household in seconds.

D.They often don’t know how to protect themselves.

E.The official naming of a new virus is often delayed.

F.Do you have a name which is easy to remember?

G.But do you know how the new coronavirus got its name?

【题目】 After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.

There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body moves back and forth from one level of sleep to the other.

Although your mind slows down, from time to time you will dream. Scientists who study sleep say that when dreaming occurs, your eyeballs begin to move more quickly (Although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.

If you have trouble falling asleep, some people recommend breathing very deeply. Other people believe that drinking warm milk will help make you drowsy.

There is also an old suggestion the counting sheep will put you to sleep!
