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.

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 ________.

Not because the 13-year-old girl is going to Harvard, but because she was rejected by Oxford University. Her case makes people talk about the long-running problems about elitism(精英主义) in British education.
“I think it’s a scandal if a child has to go to Harvard rather than getting into Oxford, don’t you?” Education Secretary David Blunkett said on May 26th in an interview on BBC radio.
British Treasury chief Gordon Brown said in a speech on May 25th it was “an absolute scandal”, a girl with those grades was turned down by Oxford’s Magdalen College. He noted that Spence comes from Monkseaton in northeastern England, where people sometimes complain they get fewer chances than people living in the richer, more populous south.
Oxford and Cambridge University now take the majority of their students—53 percent—from publicly funded schools. Elite(精英)private schools such as Eton and Harrow account for the other 47 percent, even though they serve only 7 percent of secondary students.
A BBC reporter had seen notes of Spence’s interview at Magdalen. “As with other comprehensive school pupils, she’s low in confidence and difficult to draw out of herself in spite of being able to think on her feet,” the BBC quoted the notes as saying. Still, the notes concluded that Spence “will be an excellent doctor.”
“It appears as if some of our institutions have admissions procedures which may be because of absurd prejudices against children from comprehensive schools…are not giving these children a fair crack of the whip”, Education Minister Wicks told the BBC.
5.Laura Spence was rejected by Oxford University because.
A.she was a girl of 13 years old B.she lacked confidence and she couldn’t think by herself
C.she didn’t win excellent grades
D.she was a shy girl from a comprehensive school in the poorer, less populous north
6.If Laura Spence was from such a school as Eton,.
A.she would be admitted to Oxford B.she would be accepted by Harvard
C.she could cause longrunning problems about elitism in British education
D.she wouldn’t be an excellent doctor
7.What’s the meaning of “a fair crack of the whip”in the last paragraph?
A.A good chance. B.Warning. C.Rejection. D.Admission
8.According to Education Minister Wick’s words, we know he .
A.thought there was something wrong with procedures of admissions to their institutes
B.took the side of Oxford University
C.considered giving up children from comprehensive schools D.didn’t tell the truth to the BBC
One in five managers also said being kept awake at night meant they were more likely to make mistakes, the Mori poll of 1,006 people revealed(显示).
Some 48% of people aged 35 to 44 said they did not get enough sleep compared to a national average 39%.
Among that age group, people with young children and managerial (管理的) jobs were most likely to suffer.
The report, commissioned (委托) by the think tank Demos and Ikea, said the issue of sleep had been forgotten in the work / life balance debate.
Report author Charles Leadbeater said, "On any working day, a quarter of all managers in Britain are likely to be in a bad mood because they have not slept well. "
"These sleep-deprived and shouty managers with a tendency to make mistakes are responsible for millions of British workers. It’s hardly a recipe for good management. "
And Mr. Leadbeater called on the government and employers to take action.
A small loss of sleep is likely to have a big impact on people who lead stressful lives.
"Stressed out parents are already not sleeping enough. They are the people most likely to have their sleep disrupted and they are least able to recover."
Apart from children keeping their parents awake, worrying about work is the biggest cause of wakefulness at night among managers.
Women are five times more likely than men to lose sleep because their partners snore (打呼噜).
The report predicted that there was likely to be a growing market of sleep-deprived people, with an increase in "public napping".
Opportunities to take a nap at work are also likely to increase, and the report recommended that employers take their responsibility for ensuring employees were well slept more seriously.
Peter Jelkeby, marketing manager at Ikea, said the research confirmed suspicions Britons were not getting enough sleep.
And he added: "This is having a detrimental effect on our society as a whole. "
9. Which of following is true according to the text?
A. Half of the people say a lack of sleep makes them irritable.
B. 20% managers said being kept awake at night meant they were more likely to make mistakes.
C. Some 48% of people said they did not get enough sleep.
D. People with young children and managerial jobs were most likely to suffer.
10. What does the underlined word "detrimental" mean?
A 良好的. B.有害的 C.片面的 D.致命的
11. Who that suffered sleep disrupted are least able to recover?
A. The bosses. B. Managers.
C. People aged 35 to 44. D. Stressed out parents.
12. Apart from children keeping: their parents awake, ________is the biggest cause of wakefulness at night among managers.
A. worrying about work B. their partners’ snoring
C. the relationship D. working conditions
Tim Flowers and Tony Yeo, from Sussex University’s School of Biological Sciences,. have spent several years researching how crops, such as rice, could be made to grow in water that has become salty. The pairs have recently begun a three-year programme, funded by the Biotechnology and Biological Sciences Research Council, to establish which genes enable some plants to survive salty conditions. The aim is to breed this capability into crops, starting with rice.
It is estimated that each year more than 10 million hectares (公顷) of agricultural land are lost because salt gets into the soil and stunts(防碍生长) plants. The problem is caused by several factors. In the tropics, mangroves that create swamps (沼泽) and traditionally formed barriers to sea water have been cut down. In the Mediterranean, a series of droughts have caused the water table to drop, allowing sea water to seep (渗透) in. In Latin America, irrigation often causes problems when water is evaporated by the heat, leaving, salt deposits behind.
Excess salt then enters the plants and prevents them functioning normally. Heavy concentrations of minerals in the plants stop them drawing up the water they need to survive.
To overcome these problems. Flowers and Yeo decided to breed rice plants that take in very little salt and store what they do absorb in cells that do not affect the plants’ growth. They have started to breed these characteristics into a new rice crop, but it will take about eight harvests before the resulting seeds are ready to be considered for commercial use.
Once the characteristics for surviving salty soil are known, Flowers and Yeo will try to breed the appropriate genes into all manners of crops and plants. Land that has been abandoned to nature will then be able to bloom again, providing much needed food for the poorer countries of the world.
4. Which of the following statements about Flowers and Yeo is true?
A. They are students at Sussex University. B. They are rice breeders.
5. Which of the following is NOT mentioned as a cause of the problem discussed in the passage?
A. Natural barriers to sea water have been destroyed.
B. The water table has gone down after droughts.
C. Sea level has been continuously rising.
D. Evaporation of water leaves salt behind.
6. The word "affect" in Paragraph 5 could be best replaced by________.
A. influence B. effect C. stop D. present
7. The attitude of the author towards the research project is________.
A. positive B. negative C. suspicious D. indifferent
Washoe was born in 1965 in Africa, where she was captured by the Air Force and taken to the US for research use in the space program. In 1966, she left the program and began living with two scientists, Allen and Beatrix Gardner, who led a project to teach the chimp American Sign Language (ASL) in Washoe, Nevada, for which it was named. Washoe had been living on Central Washington University’s Ellensburg Campus since 1980. She had a vocabulary of about 250 words. Also, Washoe taught sign language to three younger chimps: Tatu, 31, Loulis, 29, and Dar, 31
Primate (灵长类) researcher Jane Goodall, in Fouts’ book Next of Kin, noted the importance of the work with Washoe. “Roger, through his ongoing conversations with Washoe and her extended family, has opened a window into a chimpanzee’s mind,” Goodall said.
Though previous efforts to teach chimps spoken languages had failed, the researchers believed there was a better chance using signs. But Washoe’s language skills were disputed by scientists who believed that language is unique to humans. Among those who doubted that chimps could use language were linguist (语言学家) Noam Chomsky and Harvard scientist Steven Pinker. They believed primates simply learn to perform certain acts in order to receive rewards, and do not acquire true language.

There was yet another high school list I made. One day I came across a newspaper article about an English professor at a nearby state college. The article had a list of the “hundred most important books of Western Civilization.” “More than anything else in my life,” the professor told the reporter with finality , “these books have made me all that I am.” That was the kind of words I couldn’t ignore. I kept the list for the several months it took me to read all of the titles. Most books, of course, I hardly understood. While reading Plato"s The Republic, for example, I needed to keep looking at the introduction of the book to remind myself what the text was about. However, with the special patience and superstition (迷信) of a schoolboy, I looked at every word of the text. And by me time I reached the last word, pleased, I persuaded myself that I had read The Republic, and seriously crossed Plato off my list
