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 2009.
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.
21. 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
22.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.
23.The passage implies but doesn’t states that ______.
A.putting living cells into a sleep-like state is full of failure
B.Biggiogera is not confident enough with the experiment
C.human’s hibernmation needs no energy
D.medical research is the key to space flight hibernation system
24.By designing a suitable protective shelter，astronauts can______.
A.have a good hibernation
B.1essen the pressure of traveling in space
C.feed themselves in spaceship
D.monitor their body changes
25.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
Maggie was very glad that James was not a frequent visitor to the house.So far as the children were concerned，they had a mystery about him that stirred their imagination.He stirred Maggie’s anger，however，So that she often said to her husband，“It’s mercy that brother of yours doesn’t come oftener.’’

That gave her some satisfaction, for James, though rich, was mean. He always went home by the last train, just after two o'clock.
Maggie's children secretly stared at their uncle. They could not forget that he had, in their mother's words, " lost two wives and taken a third, "They wondered about those two unfortunate lost ladies.
