Very old people do raise moral problems for almost everyone who comes in contact with them. Their values—this can’t be repeated too often—are not necessarily our values. Physical comfort, cleanness and order are not necessarily the most important things. The social services from time to time find themselves faced with a flat with decaying food covered by small worms, and an old person lying alone in bed, taking no notice of the worms. But is it interfering(干涉) with personal freedom to insist that they go to live with some of their relatives so that they might be taken better care of? Some social workers, the ones who clear up the worms, think we are in danger of carrying this concept of personal freedom to the point where serious risks are being taken with the health and safety of the old.
Indeed, the old can be easily hurt or harmed. The body is like a car, it needs more mechanical maintenance(机械维修，保养) as it gets older. You can carry this comparison right through to the provision of spare parts. But never forget that such operations are painful experiences, however good the results will be. And at what point should you stop to treat the old body? Is it morally right to try to push off death by seeking the development of drugs to excite the forgetful old mind and to activate the old body, knowing that it is designed to die? You can’t ask doctors or scientists to decide, because so long as they can see the technical opportunities, they will feel bound to give them a try, on the principle that while there’s life, there’s hope. w.w.w.k.s.5.u.c.o.m
When you talk to the old people, however, you are forced to the conclusion that whether age is happy or unpleasant depends less on money or on health than it does on your ability to have fun.
1. What does the passage mainly tell us?
A. The values are different between the old and the young. B. The moral problems raised by old people.
C. The personal freedom for the old. D. Old people’s viewpoint on life.
2. We can know from the first paragraph that________.
A. Very old people would like to live alone to have more personal freedom.
B. Very old people are able to keep their room clean.
C. Very old people like to live with their children.
D. Social services have nothing to do with very old people.
3. According to the author, which of the following is right?
A. The older a person, the more care he needs. B. Too much emphasis has been put on old people’s values.
C. The human body can’t be compared to a car. D. It is easy to provide spare parts for old people.
4.The underlined word “it” in the last paragraph refers to “________”.
A. their money or their health B. the conclusion you come to
C. your talk to the old people D. whether age is happy or unpleasant
查看习题详情和答案>>There is an endless supply of stories about sleepwalkers (梦游者). People have been said to climb on roofs, solve mathematical problems, write music, walk through windows, and do murder in their sleep.
In Revere, Massachusetts, a hundred policemen searched for a lost boy who left his home in his sleep and woke up five hours later on a strange sofa in a strange living room, with no idea how he had got there.
At the University of Lowa, WWW.K**S*858$$U.COMa student was reported to have the habit of getting up in the middle of the night and walking three-quarters of a mile to the Lowa River. He would take a swim and then go back to his room to bed.
An American expert on sleep claims (声称) that he has never seen a sleepwalker. He is said to know more about sleep than any other living man, and during the last thirty-five years he has lost a lot of sleep watching people sleep. He says, “Of course, I know that there are sleepwalkers because I have read about them in the newspapers. But none of my sleepers ever walked, and if I were to advertise for sleepwalkers for an experiment, I doubt whether I would get many takers (应征者).”
Sleepwalking, however, is a scientific reality. It is one of those strange things that sometimes look quite fantastic (怪诞的). Doctors say that sleepwalking is much more common than is generally supposed. Many sleepwalkers do not try to find help and their sleepwalking is never recorded.
Generally speaking, sleepwalkers are people who ________.
A. climb on roofs B. walk through windows
C. do fantastic things during their sleep D. walk in a half-awake state
It was reported that a boy ________.
A. was found on a strange sofa, telling how he had got there
B. slept in his own room but woke up in a strange room
C. lost his way five hours after he left home
D. was searched for by policemen when he lost his way
There was a college student who got into the habit of ________.
A. getting up in the middle of the night and walking down to the river
B. walking three-quarters of a mile every day
C. swimming in the Lowa River before going to bed
D. walking about before he went to bed
Why do people think sleepwalking is nothing but a fantastic thing which doesn’t have any explanation?
A. It is so common that it needn’t be recorded.
B. Scientists take no interest in it.
C. Most sleepwalkers do not seek help for their problem.
D. No records about it have been made.

Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
“To provide enough power, we need certain methods with high energy density(密度)”，said Jae Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries.”
Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.
“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”
His new idea is not only in the battery’s size, but also in its semiconductor(半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”
Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.
1. Which of the following is true of Jae Kwon?
A. He teaches chemistry at MU.
B. He developed a chemical battery.
C. He is working on a nuclear energy source.
D. He made a breakthrough in computer engineering.
2. Jae Kwon gave examples in Paragraph 4_________.
A. to show chemical batteries are widely applied.
B. to introduce nuclear batteries can be safely used.[来源:Z.xx.k.Com]
C. to describe a nuclear-powered system.
D. to introduce various energy sources.
3. Liquid semiconductor is used to _________.
A. get rid of the radioactive waste
B. test the power of nuclear batteries.
C. decrease the size of nuclear batteries
D. reduce the damage to lattice structure.
4. According to Jae Kwon, his nuclear battery _______.
A. uses a solid semiconductor
B. will soon replace the present ones.
C. could be extremely thin
D. has passed the final test.
5. The text is most probably a ________.
A. science news report B. book review
