单选题Happiness can be described as a positive mood and a pleasant state of mind. According to recent polls (民意测试), sixty to seventy percent of Americans consider themselves to be moderately happy and one in twenty persons feel very unhappy. Psychologists have been studying the factors that contribute to happiness. It is not predictable nor is a person in an apparently ideal situation necessarily happy. The ideal situation may have little to do with his actual feelings. A good education and income are usually considered necessary for happiness. Though both may contribute, they are only chief factors if the person is seriously undereducated or actually suffering from lack of physical needs. The rich are not likely to be happier than the middle-income group or even those with very low incomes. People with college educations are somewhat happier than those who did not graduate from high school, and it is believed that this is mainly because they have more opportunity to control their lives. Yet people with a high income and a college education may be less happy than those with the same income and no college education. Poor health does not rule out happiness except for the severely disabled or those in pain. Learning to cope with a health problem can contribute to happiness. Those with a good sex life are happier in general, but those who have a loving, affectionate relationship are happier than those who rely on sex alone. Love has a higher correlation with happiness than any other factors. It should be noted that people quickly get used to what they have, and they are happiest when they feel they are increasing their level no matter where it stands at a given time. Children whose parents were happily married have happier childhoods yet they are not necessarily happier adults when they grow up. The best formula for happiness is to be able to develop the ability to tolerate frustration, to have a personal involvement and commitment, and to develop self-confidence and self-esteem.

单选题How efficient is our system of criminal trial? Does it really do the basic job we ask of it—convicting the guilty and acquitting the innocent? It is often said that the British trail system is more like a game than a serious attempt to do justice. The lawyers on each side are so engrossed in playing hard to win, challenging each other and the judge on technical points, that the object of finding out the truth is almost forgotten. All the effort is concentrated on the big day, on the dramatic cross examination of the key witnesses in front of the jury. Critics like to compare our "adversarial" system (resembling two adversaries engaged in a contest) with the continental "inquisitorial" system, under which the judge plays a more important inquiring role. In early times, in the Middle Ages, the systems of trial across Europe were similar. At that time trial by "ordeal"—especially a religious event—was the main way of testing guilt or innocence. When this way eventually abandoned the two systems parted company. On the continent church-trained legal officials took over the function of both prosecuting and judging, while in England these were largely left to lay people, the Justice of the Peace and this meant that all the evidence had to be put to them orally. This historical accident dominates procedure even today, with all evidence being given in open court by word of mouth on the crucial day. On the other hand, in France for instance, all the evidence is written before the trial under supervision by an investigating judge. This exhaustive pretrial looks very undramatic; much of it is just a public checking of the written records already gathered. The Americans adopted the British system lock, stock and barrel and enshrined it in their constitution. But, while the basic features of our systems are common, there are now significant differences in the way serious cases are handled. First, because the U.S.A. has virtually no contempt of court laws to prevent pretrial publicity in the newspaper and on television, Americans lawyers are allowed to question jurors about knowledge and beliefs. In Britain this is virtually never allowed, and a random selection of jurors who are presumed not to be prejudiced are empanelled. Secondly, there is no separate profession of barrister in the United States, and both prosecution and defense lawyers who are to present cases in court prepare themselves. They go out and visit the scene, track down and interview witnesses, and familiarize themselves personally with the background. In Britain it is the solicitor who prepares the case, and the barrister who appears in court is not even allowed to meet witness beforehand. British barristers also alternate doing both prosecution and defense work. Being kept distant from the preparation and regularly appearing for both sides, barristers are said to avoid becoming too personally involved, and can approach cases more dispassionately. American lawyers, however, often know their cases better. Reformers rightly want to learn from other countries" mistakes and successes. But what is clear is that justice systems, largely because they are the result of long historical growth, are peculiarly difficult to adapt piecemeal.

单选题"I've never met a human worth cloning," says cloning expert Mark Westhusin from the cramped confines of his lab at Texas A & M University. "It's a stupid endeavor.' That's an interesting choice of adjective, coming from a man who has spent millions of dollars trying to clone a 13-year-old dog named Missy. So far, he and his team have not succeeded, though they have cloned two calves and expect to clone a cat soon. They just might succeed in cloning Missy later this year--or perhaps not for another five years. It seems the reproductive system of man's best friend is one of the mysteries of modem science. Westhusin's experience with cloning animals leaves him vexed by all this talk of human cloning. In three years of work on the Missyplicity project, using hundreds upon hundreds of canine eggs, the A&M team has produced only a dozen or so embryos carrying Missy's DNA. None have survived the transfer to a surrogate mother. The wastage of eggs and the many spontaneously aborted fetuses may be acceptable when you're dealing with cats or bulls, he argues, but not with humans. "Cloning is incredibly inefficient, and also dangerous," he says. Even so, dog cloning is a commercial opportunity, with a nice research payoff. Ever since Dolly, the sheep, was cloned in 1997, Westhusin's phone at A&M College of Veterinary Medicine has been ringing busily. Cost is no obstacle for customers like Missy's mysterious owner, who wishes him remain unknown to protect his privacy. He's plopped down $ 3. 7 million so far to fund the research because he wants a twin to carry on Missy's fine qualities after she dies. But he knows her clone may not have her temperament. In a statement of purpose, Missy's owner and the A&M team say they are "both looking forward to studying the ways that her clone differs from Missy." The fate of the dog samples will depend on Westhusin's work. He knows that even if he gets a dog viably pregnant, the offspring, should they survive, will face the problems shown at birth by other cloned animals: abnormalities like immature lungs and heart and weight problems. "Why would you ever want to clone humans," Westhusin asks, "when we're not even close to getting it worked out in animals yet?/

单选题Where one stage of child development has been left out, or not sufficiently experienced, the child may have to go back and capture the experience of it. A good home makes this possible, for example by providing the opportunity for the child to play with a clockwork car or toy railway train up to any age if he still needs to do so. This principle, in fact, underlies all psychological treatment of children in difficulties with their development, and is the basis of work in child clinics. The beginnings of discipline are in the nursery. Even the youngest baby is taught by gradual stages to wait for food, to sleep and wake at regular intervals and so on. If the child feels the world around him is a warm and friendly one, he slowly accepts its rhythm and accustoms himself to conforming to its demands. Learning to wait for things, particularly for food, is a very important element in upbringing, and is achieved successfully only if too great demands are not made before the child can understand them. Every parent watches eagerly the child's acquisition of each new skill—the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feeling of failure and states of anxiety in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural zest for life and his desire to find out new things for himself. Learning together is a fruit source of relationship between children and parents. By playing together, parents learn more about their children and children learn more from their parents. Toys and games which both parents and children can share are an important means of achieving this co-operation. Building-block toys, jigsaw puzzles and crossword are good examples. Parents vary greatly in their degree of strictness or indulgence towards their children. Some may be especially strict in money matters, others are severe over times of coming home at night, punctuality for meals or personal cleanliness. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child's own happiness and well-being.
