Unless we spend money to spot and prevent asteroids now,one might crash into Earth and destroy life as we know it,say some scientists.
Asteroids are bigger versions of the meteoroids(流星)that race across the night sky. Most orbit the sun far from Earth and don't threaten us. But there are also thousands whose orbits put them on a collision course with Earth.
Buy $ 50 million worth of new telescopes right now. Then spend $ 10 million 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 an asteroid 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. “It's that simple.”
The cure,though,might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday(毁灭性的) rocks than from a great nuclear fleet set against them,” said a New York Times article.
1.What does the passage say about asteroids and meteoroids?
A. They are heavenly bodies different in composition.
B. They are heavenly bodies similar in nature.
C. There are more asteroids than meteoroids.
D. Asteroids are more mysterious than meteoroids.
2. What do scientists say about the collision of an asteroid with Earth?
A. It is very unlikely but the danger exists.
B. Such a collision might occur once every 25 years.
C. Collisions of smaller asteroids with Earth occur more often than expected.
D. It's still too early to say whether such a collision might occur.
3. What do people think of the suggestion of using nuclear weapons to alter the course of asteroids?
A. It sounds practical but it may not solve the problem.
B. It may create more problems than it might solve.
C. It is a waste of money because a collision of asteroids with Earth is very unlikely.
D. Further research should be done before it is proved applicable.

No one knows why we sleep, but it’s certain that we need to. People who are prevented from sleeping begin to suffer obvious effects after a few days—they think less clearly, and they fall asleep during the working hours; some may have hallucinations(幻觉).
There are no rules about sleep. Generally speaking, grown-ups sleep about 7 and a half hours each night and probably more than 60 per cent get between seven and eight hours. But perhaps eight per cent are quite happy with 5 hours or less, and four per cent or so find that they want ten hours or more. If you feel all right, you’re probably getting enough sleep. The important thing is not to worry how much other people get—their needs may be different. Exercise doesn’t seem to increase the need for sleep—office workers, for example, sleep for about as long as people doing physically active work.
Children sleep more than grown-ups—perhaps 14 to 18 hours soon after birth, going down to grown-up levels by early teenage. Sleep patterns also tend(倾向) to be different in the elderly, who may sleep less at night than they did when younger, find sleep getting more broken, and often make it a rule to sleep during the daytime.
1.According to the passage, some people are unable to think clearly because ___________ .
A. they have hallucinations
B. they feel sleepy during the working hours
C. they don’t have enough sleep
D. they are certain to be kept from going to bed
2.Which of the following is TRUE?
A. All grown-ups must have at least eight-hour sleep.
B. Most of grown-ups sleep for seven or eight hours.
C. Quite a few people need only 5 hours or less for them to sleep.
D. No grown-ups sleep more than ten hours.
3.Whether you have got enough sleep is judged by__________.
A. how many hours you have slept
B. how many hours you need to sleep
C. whether you do exercise and physical work
D. whether you feel fresh and energetic
4.According to the passage, a boy of 14 years old sleeps__________.
A. as long hours as a grown-up
B. much longer hours than a grown-up
C. for 14 hours each night
D. for less than 8 hours per night

They go up and they go down. They take people from one floor of a building to the exact same spot on another floor. A new technology will break elevators free from their vertical (垂直的) prisons, allowing them to move side to side, at an angle (角度), even go outside into a city. German company Thyssenkrupp has developed a new kind of elevator that uses maglev (磁悬浮) technology to move elevator cabins. Called Multi, these elevators are no longer limited to a single vertical path.
A funny thing happens when elevators can go anywhere. Tall buildings, which are designed to work around elevators, can start taking on different shapes. They can go wide, add towers or go in unusual directions, and make room for green spaces that otherwise would have been an inconvenience. A single elevator can run from the east side of the first floor to the far west side of the 30th, no transferring or walking necessary. It gets even more interesting when an elevator leaves the building. Patrick Bass, Thyssenkrupp’s North America CEO, has worked in the elevator industry for 26 years. He thinks these elevators will create new transportation networks to support the cities of the future. As more people go into cities, there’s a renewed interest in creating energy efficient spaces. Moving people around quickly is a huge part of that.
He imagines Multi working perfectly with other Thyssenkrupp technology like the Accel moving walkway. Accel, which also uses maglev technology, speeds up after you step on and can go twice the speed of a regular moving walkway. It was the first use of maglev technology outside of a train. The Accel is already in use in some cities now.
1.Compared with traditional elevators, Multi can __________.
A.go more smoothly B.go in any directions
C.go up and down freely D.go directly from floor to floor
2.What will happen to buildings with Multi?
A.They will hold more people.
B.They will become much higher.
C.They will be in different shapes.
D.They will be connected to one another.
3.In what way can Multi support cities of the future?
A.They save space in cities.
B.They help avoid the rush hours.
C.They help people save money.
D.They help move people around quickly.
4.Why is the Accel mentioned in the last paragraph?
A.To show how Multi works.
B.To show the importance of the Accel.
C.To tell us other products by Thyssenkrupp.
D.To explain the wide use of maglev technology.

They like using the Internet. They have lots of pocket money to spend, and they spend a higher proportion of it online than the rest of us. Teenagers are just the sort of people an online seller is interested in, and the things they want to buy games, CDs and clothing are easily sold on the Web.
But paying online is a tricky business for consumers who are too young to own credit cards. Most have to use a parent’s card. They want a service that allows them to spend money.
That may come sooner than they think: new ways to take pocket money into cyber (网络的) space are coming out rapidly on both sides of the Atlantic. If successful, these products can stimulate (刺激)online sales.
In general, teenagers spend huge amounts: $153bn (billion) in the US last year and £20bn annually in the UK. Most teenagers have access to the Internet at home or at school 88 percent in the US, 69 percent in the UK. According to the Jupiter Research, one in eight of those with Internet access has bought something online mainly CDs and books.
In most cases, parents pay for these purchases with credit cards, an arrangement that is often unsatisfactory for them and their children. Pressing parents to spend online is less productive than pressing on the high street. They are more likely to ask “Why?” if you ask to spend some money online.
One way to help teenagers change notes and coins into cyber cash is through prepaid cards such as Internet Cash in the US and Smart cards in the UK. Similar to those for pay-as-you-go mobile telephones, they are sold in amounts such as£20 or $50 with a concealed (隐藏的) 14-digit number that can be used to load the cash into an online account.
1.What does the word “They” in paragraph 1 refer to?
A. Sellers. B. Teenagers C. Buyers. D. Parents.
2.According to the passage, which of the following statements is TRUE?
A. Most teenagers in the US and the UK have bought something online.
B. Teenagers pay for goods online with their own credit cards.
C. More than half of the teenagers in the US and the UK have Internet access.
D. Teenagers found it easier to persuade parents to buy online than in a shop.
