Have you ever dreamed of visiting a planet in the Milk Way? While the trip sounds exciting, it would take years and years to reach your destination. So in the future, bedtime for astronauts may be more than a few hours of regular shut-eye. They would have to sleep for years.

European researchers are now conducting hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel a reality," said Mark Ayre of the European Space Agency last month.

What seems like science fiction is not completely unlikely. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don't age. They have now moved on to small, non-hibernating mammals like rats. The results will be out by the end of 2004.

A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex.

"It's like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy's University of Pavia.

Just like bears and frogs, the hibernation of human beings would cause a person's metabolism (新陈代谢) to lower so they would need less energy.

Medical research, however, is just half of a space flight hibernation system.

There is the challenge of designing a suitable protective shelter. Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor (监控) life functions and serve the physiological needs of the hibernator.

According to Ayre, the six-person Human Outer Planets Exploration Mission to Jupiter's moon (木星的卫星) Callisto, could be an opportunity to use human hibernation. The mission aims to send six humans on a five-year flight to Callisto, where they will spend 30 days, in 2045.

9. European researchers are conducting hibernation experiments to ________.

A. ensure astronauts to get a complete sleep  B. find the secret of some creatures

C. make preparations for the journey to Jupiter’s moon Callisto

D. know if man can sleep for years

 10. The sentence “What seems like science fiction is not completely unlikely” means ______.

A. Science fiction is people’s imagination.

B. Science fiction is imaginative, but it can be realized.

C. Things seem impossible may come true.

D. Things described in science fiction are sure to become true.

11. The passage is implied but doesn’t states that ________.

A. putting living cells into a sleep-like state is full of failure

B. Biggiogera is confident with the experiment

C. human’s hibernation needs no energy

D. medical research is the key to space flight hibernation system

12. By designing a suitable protective shelter, astronauts can ________.

A. have a good hibernation        B. lessen the pressure of traveling in space

C. feed themselves in spaceship    D. moinitor their body changes

13. What’s the best title for the passage?

A. Six humans to fly to Callisto  B. Human hibernation improves health

C. Space travel attracts people   D. Deep sleep for deep space travel

Every autumn, as families across the United States get ready to send their kids to college, the economics of higher education receive renewed attention. College is expensive and becoming more so in the U. S. The situation raises two questions: Why does it cost so much, and how can students and their families afford it?

Several studies published in the past few weeks reflect on these questions. The findings provide comfort to poor families.

First, it appears that only the minority actually pay the "high price". A study by the US Education Department's National Center for Education Statistics found that 55 percent of college students last year received some forms of help--scholarships, loans(贷款)or jobs.

Other factors are also at work. The government has increased the size of its grants (补助金)to lower-income students. Grants, unlike loans, don't have to he repaid and are awarded only to college students who have not earned a bachelor's or professional degree.

At the same time, most colleges are spending more on undergraduate education than they are collecting in tuition fees. A study, which is part of the Williams College Project on the Economics of Higher Education, reaches the conclusion that on average colleges “subsidize (赞助)” their students. The results of these studies, however, leave unanswered the questions of whether educational costs are higher than they need to be. Some experts argue that much of the college cost results from educational competition for fame, students and facilities.

This puts upward pressure on tuition, hut many colleges feel that good fame will enable them to attract students even if they charge them more.

Therefore, until something important changes in the marketplace, costs seem likely to continue rising. And American families will continue to beat down the doors of the high price "college in the end．

1．From the fourth paragraph of the passage we can conclude that _______.

A．American families earn only a little money every year

B．American families pay little attention to education

C．American students often have to stop their studies

D．American colleges have different ways to help poor students

2．In the writer's opinion, for students from lower-income families, the best way is ________.

       A．to find a good job and make money         

       B．to borrow money from the banks

       C．to ask for grants                             

       D．to borrow money from friends

3．It can be inferred that in America _______.

       A．famous colleges only accept rich students.   

B．famous colleges charge their students more money

       C．the government spends little money on education

       D．families often break the doors of colleges

4．The writer of this passage seems to hold the opinion that _______.

       A．college fees rise too fast for poor families.    

B．poor people should borrow money from banks

       C．poor people don’t need to send their children to college

D．colleges should get more money to improve themselves

Shoopping for clothes is not the same experience for a man as it is for a woman. A man goes shopping because he needs something. His purpose is settled and decided in advance. ____1.____. All men simply walk into a shop and ask the assistant for what they want.

The most important thing in her mind is the thought of finding something that everyone thinks suits her. They are always on the look-out for the unexpected bargain.

Today many people say that women have the same chance as men in society. But this was not always so. In the past, women all over the world had to fight to get the same chance as men in education and jobs. Many people said that women should not receive much education because they would not do as well as men when they went to work.

One woman who showed that women should have the same chance was Marie, a scientist. In the 1800s scientists knew that a metal, uranium, gave off radiation. They also knew how much radiation came from his element. But they didn’t know what this radiation was like; they wondered why and how uranium gave off radiation. Marie Curie set out to answer these questions. In one of her experiments she was studying a certain material which, she knew, contained uranium, But it gave off 4 times as much radiation as usually does. What could explain this fact? Marie Curie thought that there must be another source of radiation in this material.

In 1898 Marie Curie set out to find out this new source of radiation, which she named “radium”. Her husband, who was also a scientist, helped her. They set up a laboratory in an old building behind a school. For four years Curies searched, doing many experiments, And one morning in 1902 Marie found the source of the radiation.

Marie Curie proved to the world that there was element that gave off radiation. And she also proved to the world that, if women are given truly equal chance, they can really help society.

1.The scientists of Marie Curie’s day knew .

A．that uranium gave off radiation

B．that radium gave off radiation

C．that there was some radium in uranium

D．that uranium and radium both gave off radiation

2.The Curies found the element radium .

A．with other scientists’ help

B．by asking some famous scientists

C．by doing many experiments

D．with their teachers’ help

3.In the past many people thought .

A．that women must get the same chance as men in education and jobs

B．that women should receive much education

C．that women should get good jobs

D．that women could not do the work well

4.Marie Curie proved to people .

A．that there was a new element uranium

B．that there was a new element radium

C．that women could do their work as well as men if they were really given the same conditions

D．both B and C
