Social distancing is not a new concept in the natural world where infectious diseases are commonplace. Through specialized senses animals can detect certain diseases and change their behavior to avoid getting ill.

In 1966,while studying chimps(猩猩）in a Tanzanian national park,zoologist Jane Goodall observed a chimp named McGregor who had caught a highly infectious virus. His fellow chimps attacked him and threw him out of the troop. In one instance,McGregor approached chimps in a tree. He reached out a hand in greeting,but the others moved away without a back-ward glance.

＂For a full two minutes,old McGregor sat motionless,staring after them, "Goodall notes in her 1971 book In the Shadow of Man. "It's really not that different to how some societies react today to such a tragedy. "

Not all animals are so aggressive toward their ailing neighbors.Sometimes it's as simple as avoiding those who may infect you.

When Kiesecker,a lead scientist in America,studied American bullfrog in the late 1990s, he found that bullfrogs could not only detect a deadly smell of infection in other bullfrogs,but healthy members actively avoided those that were sick. Bullfrogs rely on chemicals' signals to determine who is sick or not.

Caribbean lobsters also shun diseased members of their community,well before they become infectious. It takes about eight weeks for lobsters infected with the deadly virus Panulirus argus mininuceovirus to become dangerous to others. Normally social animals,lobsters begin keeping away from the diseased as early as four weeks after infection-once the lobsters can smell certain chemicals released by sick individuals.

Overall,it's important to note that,unlike us,animals don't realize if they stay home,they might actually reduce the infection rate, "Kiesecker explains. "As humans, we have that ability. It's a big difference."

1. （1） What can we learn about the chimps from Goodall's observation?

   A . They kept a distance from one another. B . They became aggressive when infected. C . The infected avoided contact with others. D . The infected were forced to leave the group.
3. （2） What does the underlined word"shun"in Paragraph 6 probably mean?

   A . Avoid. B . Cure. C . Get rid of. D . Get along with.
5. （3） How are humans different from animals according to Kiesecker?

   A . Humans are more sensitive to virus. B . Humans are less likely to get infected. C . Humans treat infectious diseases in a wiser way. D . Humans can detect chemical signals more quickly.
7. （4） Which might be the best title for the text?

   A . Help Me Out B . Leave Me Alone C . Stay Away From Us D . Stay Home Stay Healthy

At 9, Simone learned why she couldn't sit still:She had ADHD(多动症）。 Her brain moved fast and her body did too-which made it hard for her to concentrate in school but which also made her an amazing gymnast. "The challenges we face help define who we are, "Simone wrote. "My challenge is also my

Reading newspapers has become an important part of everyday life. Some people read newspapers as the first thing to do in the morning, others read newspapers as soon as they have free time during the day so that they can learn what is happening in the world.

Sometimes, we do not have enough time to read all the news carefully, so we just take a quick look at the front page. At other times, we may be in such a hurry that we only have a few minutes to look at the headlines of the passages.

Newspapers can be found everywhere in the world. We can get many different kinds of newspapers in big cities, but in some mountain villages we can see few newspapers.

Some newspapers are published once a week, but most of the papers are published once a day with many pages, some even published twice a day! You know different people enjoy reading different newspapers. Some like world news, and others prefer short stories. They just choose what they are interested in.

Today newspapers in English have the largest number of readers in the world. The English language is so popular that many Chinese students are reading English newspapers such as China Daily or 21^st Century. They bring us more and more information with the internet.

Having parked near the car wash beside the supermarket, I came away to wait for my wife to come from work. Coming my way from across the parking lot was what society would consider a bum (流浪汉). From the looks of him, he had no car, no home, no clean clothes, and no money. There are times when you feel generous but there are other times that you just don't want to be bothered . This was one of those "don't want to be bothered times."

"I hope he doesn't ask me for any money," I thought. He didn't. He came and sat on the seat by the bus stop but he didn't look like he could have enough money to even ride the bus. After a few minutes he spoke, "That's a very pretty car". He was ragged (衣着破旧的) but he had an air of dignity around him. I said, "thanks," without taking a look at him.

He sat there quietly for a moment. The expected begging for money never came. As the silence between us widened something inside said, "Ask him if he needs any help." I was sure that he would say "yes". So I asked, "Do you need any help?"

He answered in three simple words that I shall never forget. The three words shook me. "Don't we all?" he said.

I was feeling successful and important, above a bum in the street, until those three words hit me. Don't we all? I needed help. Maybe not for bus fare or a place to sleep, but I needed help. I reached in my wallet and gave him not only enough for bus fare, but enough to get a warm meal and shelter for the day. Those three little words still ring true. No matter how much you have, you need help too. However, no matter how little you have, you can give help too.

1. （1） The author walked away from the car wash to ____. 

   A . go to work B . wash his car C . go shopping D . meet his wife
3. （2） When the author first saw the bum, he planned to ____.

   A . ignore his difficulty B . give him a lesson C . offer him some help D . make friends with him
5. （3） When the bum said "Don't we all?", the author felt ____.

   A . satisfied B . shy C . sad D . shocked
7. （4） What is the best title for the text?

   A . The clever bum B . Never lose your dignity C . Don't we all need help? D . To give or not?

locals.

In one of the most amazing  （discover) in recent years,scientists at a European Institute (find) a way to turn one chemical that causes air pollution into a resource. Carbon dioxide is a form of pollution (release) from the burning of fuels such as coal,oil and wood. Transportation and electricity production are its major sources. There searchers at Rutgers University have created unusual technique which changes carbon dioxide into valuable raw materials.Using cheap and plentiful metals, the process （efficient) turns carbon dioxide gas into water and carbon blocks that can be used as building blocks. The process is 99% efficient, which is the main reason （account) for this result. Products that can be produced by this technique include raw materials for use in clothing,chemical and （medicine) industries.The scientists have also created a company （develop) commercial applications for this technique . As a famous American engineer puts it, "Pollution is nothing but the resources we are not harvesting." the development and application of this new technology,people may find value in  once was considered to be harmful waste.
