Sometimes teens need to have some time away from their families. They may want' to move ou
t of the family home for a while.

Many parents will say no to this demand. But experts say it might be a good idea to let your teens live with a friend or relative.

"It was the break I needed at the time," said Richard Lerner. He is talking about the time he spent living with his grandmother when he was 15.

"It allowed me to be a different person than I was with my parents." Lerner said. He now heads the Institute for Children, Youth and Families at Michigan State University.

Experts say teens living away from their families can test new ways of thinking and getting along with people. They may see new solutions (解答) to problems.

This is different from running away, the experts stress. Runaways are often fleeing serious problems.

Some teens who want some time away from family attend a structured summer program. Others live for a while with a relative or with the family of a friend.

If there is conflict (冲突) at home, having a teen live elsewhere can benefit other family members. It gives everyone space to develop better relationships.

Joseph Kett teaches history at the University of Virginia in Charlottesville. He says living at home until the late teen years has become the norm (准则) only in recent times.

"In the 17th century, children were often sent to live in other people's homes when they were about 10 or 11," he said.

Peter Sheras teaches education at the University of Virginia. He said parents should listen when a child wants to move out. They should try to find out why the child wants some time away.

Often, parents can help the child find a safe place to stay during that time. In other cases, they can meet the child's needs at home.

According to this passage, many parents think it ______ for their children to live away from them.

A.right

B.happy

C.unsafe

D.reasonable

Unless we spend money spotting and preventing asteroids now, one might crash into Earth an
d destroy life as we know, say some scientists.

Asteroids are different forms of the meteoroids that race across the night sky. Most orbits the sun far from Earth and don't threaten us. But there are also thousands of asteroids whose orbits put them on a violent coming course together with Earth.

Buy $ 50 million worth of new telescopes right now. Then spend $10 mil]ion a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we'll have a way to change its course.

Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn't be cheap.

Is it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think asteroids big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare but if one did fall it would be the end of the world. "If we don't take care of these big asteroids, they'll take care of us. "Says one scientist. "Its that simple."

The cure, though, might be worse than the disease, Do we really want fleets of nuclear weapons silting around on Earth? "The world has less to fear from doomsday rocks than from a great nuclear fleet set against them. "Said a New York Times article.

What does the passage say about asteroids and meteoroids?

A.They are heavenly bodies similar in nature.

B.There are more asteroids than meteoroids.

C.They are heavenly bodies different in composition.

D.Asteroids are more mysterious than meteoroids.

The word "Okay" is known and used by millions of people all over the world. Still, languag
e experts do not agree on where it came from.

Some say it came from the Indian peoples. When Europeans first came to America they heard hundreds of different Indian languages. Many were will developed.

One tribe especially had a well developed language. This was the Chocktaw tribe. They were farmers and fishermen whole lived in the rich Mississippi valley in what is now the state of Alabama. When problems arose, Chocktaw leaders discussed them with the tribal chief. They sat in a circle and listened to the wisdom of the chief.

He heard the different proposals, often raising and lowering his head in agreement, and saying, "Okeh," meaning "it is so."

The Indian languages have given many words to English. Twenty four of the American States almost half, have Indian names, Okalahoma, the Dakotas, Idaho, Wisconsin, Ohio and Tennessee, to name a few. And the names of many rivers, streams, mountains, cities and towns are Indian.

However, there are many people who dispute the idea that "Okay" came from the In di ans. Some say the President Andrew Jackson first used the word "Okay." Others claim the word was invented by John Jacob Astor, a fur trader of the late 1700s who became one of the world's richest men. Still others say a poor railroad clerk made up this word. His name was Obadiah Kelly and he put his initials(首写字母), O.K. on each package people gave him to ship by train.

So it goes, each story sounds reasonable and official.

But perhaps the most believable explanation is that the word "Okay" was invented by a political organization in the 1800s. Martin Van Buren was running for President. A group of people organized a club to support him. They called their political organization the "Okay Club. The letters "O" and "K" were taken from the name of Van Buren's hometown, the place where he was born, old Kinderhook, New York.

There is one thing about "Okay" that the experts do agree on: that the word is pure American and that it has spread to almost every country on earth.

There is something about the word that appeals to peoples of every language. Yet, here in America it is used mostly in speech, not in serious writing. In recent time, "Okay" has been given an official place in the English language. But it will be a long time before Americans will officially accept two expressions that come from "Okay." There are "Oke" and "Okeydoke".

______different opinions as where the word "Okay" came from are mentioned in the text.

A.Four

B.Five

C.six

D.Three

阅读理解 Researches say people traveling in traffic are three times more likely to suf
fer a heart attack. They say the risk of a heart attack is greatest within an hour of being in traffiC.

The findings are based on a German study of almost 700 people who suffered heart attacks. The patients described their activities during the four days before their heart attack. Researchers found that those who had been in traffic were three times more likely to have a heart attack within one hour, compared to those who had not been in traffiC. Most of those in the study had been traveling by car. But some had been on bicycles and others were on buses.

Research shows that people in cars and buses are exposed to ten times the amount of pollutants as people walking on the street. That is largely because they breathe in the particles and gasses released from the vehicles in front of them.

Over time, these small particles speed the buildup of a sticky substance in the blooD. This can cause blockages(阻塞) to form. in the arteries(动脉) around the heart and lead to a heart attack.

Other studies have also linked heart trouble to stress, similar to the kind that people face while driving in heavy traffiC. But the researchers of the latest study say they do not know whether the increased heart attack risk was the result of stress or pollution. They suggest it may be a combination of stress, noise and pollution. Experts say the research shows the need fro cleaner vehicles and better city planning.

9.According to the study, which of the following ways is the safest in traffic?

A. Driving a car

B. Walking on the street

C. Taking a bus

D. Riding a bicycle

9.From among the 700 people who suffered heart attacks we learn that ______.

A. those who have been in traffic are three times as many as those who have not

B. those who have been in traffic for more than one hour are most likely to suffer heart attacks

C. the risk of a heart attack is three higher among those who have been in traffic than those who have not

D. Most of the subjects (实验对象) felt uncomfortable during the four days before the attack

9.The particles released from vehicles ______.

A. build up in the blood

B. become blockages in the arteries

C. make the blood more sticky

D. do harm to the heart

9.According to the studies, which of the following is NOT a likely cause of heart attack?

A. Stress

B. Noise

C. Air pollution

D. Traffic accident

9.What suggestion do experts make to lower the risk?

A. Reducing traffic as much as possible.

B. Living away from nose.

C. Planting more trees in the city.

Sleep Deficit(不足)Judging from recent surveys, most experts in sleep behavior. agree that

Sleep Deficit(不足)

Judging from recent surveys, most experts in sleep behavior. agree that is virtually an epidemic of sleepiness in the nation. "I can't think of a single study that hasn't found Americans getting less sleep than they ought to. " says Dr. David. Even people who think they are sleeping enough would probably be better off with more rest.

The beginning of our sleep-deficit crisis can be traced to the invention of the light bulb a century ago. From diary entries and other personal accounts from the 18th 19th centuries, sleep scientists have reached the conclusion that the average person used to sleep about 9. 5 hours a night. "The best sleep habits once were forced on us, when we had nothing to do in the evening down on the farm, and it was dark. " By the 1950s and 1960s, that sleep schedule had been reduced dramatically, to between 7. 5 and 8 hours, and most people had to wake to an alarm clock. "People cheat on their sleep, and they don't even realize they're doing it, " says Dr. David. "They think they're okay because they can get by on 6. 5 hours, when they really need 7. 5, 8 or even more to feel ideally vigorous. "

"Perhaps the most merciless robber of sleep, " researchers say, "is the complexity of the day. " Whenever pressures from work, family, friends and community mount, many people consider sleep the least expensive item on his program. "In our society, you're considered dynamic if you say you only need 5. 5 hours' sleep. If you've got to get 8. 5 hours, people think you lack drive and ambition. "

To determine the consequences of sleep deficit, researchers have put subjects through a set of psychological and performance tests requiring them, for instance, to add columns of numbers or re call a page read to them only minutes earlier. "We've found that if you're in sleep deficit, performance suffers, " says Dr. David. "Shot-term memory is weakened, as are abilities to make decision and to concentrate.

People in the 18th and 19th centuries used to sleep about 5 hours a night because they had ______.

A.no drive and ambition

B.no electric lighting

C.the best sleep habits

D.a lot to of the next day

According to airline industry statistics, almost 90% of airline accidents are not survivab
le or partially survivable. But passengers can increase their chances of survival by learning and following certain tips. Experts say that you should read and listen to safety instructions before takeoff and ask question if you have uncertainties. You should fasten your seat belt low on your hips and as possible. Of course, you should also know how the release mechanism of your belt operates. During takeoffs and landings you are advised to keep your feet flat on the floor. Before takeoff you should locate the nearest exit and an alternative exit and count the rows of seats between you and the exits so that you can find them in the dark if necessary.

In the event that you are forewarned of a possible accident, you should put your hands on your ankles and keep your head down until the plane comes to a complete stop. If smoke is present in the cabin, you should keep your head low and cover your face with napkins, towels, or clothing. If possible, wet these for added protection against smoke inhalation. To evacuate as quickly as possible, follow crew commands and do not take personal belongings with you. Do not jump on escape slides before they are fully inflated, and when you jump, do so with your arms and legs extended in front of you. When you get to the ground, you should move away from the plane as quickly as possible, and never smoke near the wreckage.

According to the experts, when should travelers read and listen to safety instructions?

A.Before takeoff.

B.In an emergency.

Recently, several thousand computers in the United States were attacked by a virus. The co
mputers were slowed or shut down. But no information was lost. A computer virus is similar to a biological virus--an organism (生物体) that can harm the human body. A computer virus is a series of electronic commands that can harm a computer or the information in the computer. It infects the device (设备) secretly. It tells the computer to do something the computer's owner does not want it to do. For example, a virus could enter a bank's computer system. It might tell the system to destroy all information about money belonging to everyone with the first name United States several months ago. The virus was created by a university student studying computer science. The computers affected by the virus were in major universities, government agencies (政府机关) and private (私人) companies. They were part of a United commands in a computer at his school. The computer sent the commands to other computers through the linked telephone lines.

The virus told each computer to make many copies of itself. Within a few minutes, all the computers' power was being used to make copies of the virus. The computer could do no other work. It finally slowed down greatly, or simply stopped working. Computer experts spent many days trying to destroy the virus in the computer system.

The experts agree the virus could have been much worse. They say it could have sent orders to destroy huge amounts of electronic information.

Many experts believe, the recent computer virus showed the need for better computer security (安全). But that is a problem. The affected system provides a free exchange (交换) of ideas and information among universities, private companies and government offices. Increasing security too much would destroy this exchange. It would slow progress on many important research projects.

Which of the following statements is true?

A.Many computers were attacked by a virus in the U. S.

B.Many computers attacked by a virus in the U.S. lost their information.

C.A computer virus can harm human body.

D.A computer virus can help the computer owner do many things.
