Every day 25 million U.S. children ride school buses. The safety record for these buses is much better than for passenger cars; but nevertheless, about 10 children are killed each year riding on large school buses, and nearly four times that number are killed outside buses in the loading zones. By and large, however, the nation’s school children are transported to and from school safety.

Even though the number of school bus accidents is not large, the safety of children is always of intense public concern. While everyone wants to see children transported safely, people are divided about what needs to be done-particularly whether seat belts should be compulsory.

People in favour of seat belts on school buses-many of them parents and medical organizations-argue that seat belts are necessary not only to reduce fatality and injury, but also to teach children lessons about the importance of using them routinely in any moving vehicle. A side benefit, they point out, is that seat belts help keep children in their seats, away from the bus driver.

People who object to seat belt installation suggest that children are already well protected by the school buses that follow the Nation Highway Traffic Safety Administration’s (NHTSA) safety requirements set in 1977. They also believe that many children won’t wear seat belts anyway, and that may damage the belts or use them as weapons to hurt other children.

A new Research council report on school bus safety suggest that there are alternate safety devices and procedures that may be more effective and less expensive. For example, the study committee suggested that raising seat backs four inches may have the same safety effectiveness as seat belts.

  The report sponsored by the Department of transportation at the request of Congress, re

views seat belts extensively while taking a broader look at safety in and around school buses.

According to the passage, who has the greatest degree of control of the school buses “safety”?

A.A new Research Council.           B.The Department of Transportation.

C.The Medical Organization.         D.National Highway Traffic Safety Administration.

It may be inferred from this passage that .       .

A.many of the opponents(反对者) of seat belt installation are parents and officials of the Department of Transportation

B.proposals of seat belts on school buses would be seriously considered

C.an alternate safety device (raising seat backs four inches) may be taken into consideration

D.The Department of Transportation may either take the idea of seat belts or other measures when it reviews the whole situation

The title below which best expresses the idea of the passage is“”.

A.Making School Buses Even Safer for Children     B.Seat Belts Needed on School Buses

C.Alternate Safety Devices and Procedures         D.Safety in and around School Buses

Have you ever dreamed of visiting a planet in the Milky Way (银河系)? 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 a 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 the small, non-hibernating mammals (哺乳动物) like rats.

A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex (复杂的). "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 a challenge of designing a suitable protective shelter (栖身所). 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 (使命) to Jupiter’s moon (木星的卫星) Callisto could be an opportunity to use human hibernation. The mission aims to send six persons on a five-year flight to Callisto, where they will spend 30 days, in 2045.
