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.

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Which of the following is not a reason for the rapidity and intensity of pollution in Japan?

单选题How many of today"s ailments, or even illnesses, are purely psychological? And how far can these be alleviated by the use of drugs? For example a psychiatrist concerned mainly with the emotional problems of old people might improve their state of mind somewhat by the use of anti-depressants but he would not remove the root cause of their depression—the feeling of being useless, often unwanted and handicapped by failing physical powers. One of the most important controversies in medicine today is how far doctors, and particularly psychologists, should depend on the use of drugs for "curing" their patients. It is not merely that drugs may have been insufficiently tested and may reveal harmful side effects (as happened in the case of anti-sickness pills prescribed for expectant mothers) but the uneasiness of doctors who feel that they are treating the symptoms of a disease without removing the disease itself. On the other hand, some psychiatrists argue that in many cases (such as chronic depressive illness) it is impossible to get at the root of the illness while the patient is in a depressed state. Even prolonged psychiatric care may have no noticeable effect whereas some people can be lifted out of a depression by the use of drugs within a matter of weeks. These doctors feel not only that they have no right to withhold such treatment, but that the root cause of depression can be tackled better when the patient himself feels better. This controversy is concerned, however, with the serious psychological illnesses. It does not solve the problem of those whose headaches, indigestion, backache, etc. are due to "nerves". Commonly a busy family doctor will ascribe them to some physical cause and as a matter of routine prescribe a drug. Once again the symptoms are being cured rather than the disease itself. It may be true to say, as one doctor suggested recently, that over half of the cases that come to the ordinary doctor"s attention are not purely physical ailments. If this is so, the situation is serious indeed.

单选题Even for overachievers who are used to multitasking, the idea of watching two versions of the same television show at the same time--one on television and one on a computer—is something that is probably foreign to most people over the age of 30. To the eternally young brains that nm MTV, however, it is the next step in reshaping their business. Beginning this summer with the MTV Video Music Awards and continuing in the fall with the cable channel's live afternoon program, "Total Request Live," MTV will offer two simultaneous versions of each show, one on television and another, focusing on a behind-the-scenes narrative, on its broadband channel, MTV Overdrive. "We do tons of research on our audience, and it shows that they are instant messaging and listening to music and watching TV all at the same time," said Christina Norman, president of MTV. "We've definitely seen them become more adept at navigating through multiple media. They live comfortably in several worlds at once." The Overdrive component, located at mtv.com, will feature a sort of video digression that will continue to stream live while the television show is broadcasting commercials. For example, if a viewer wants to watch an entire music video after a snippet is shown on the "Total Request Live" video countdown, or take a backstage tour with Jamie Foxx after he finishes his onstage appearance on the set of "T.R.L." (as the show is familiarly known), Overdrive will be the place to turn. "Doing three things at once when you're 19 years old is not hard," said Dave Sirulnick, an executive vice president at MTV who oversees multiplatform production, news and music. Last Thursday at MTV's studios in Times Square, Mr. Sirulnick proved adept at doing at least two things at once, dashing between two control rooms that were steps away from each other just down the hallway from the "T.R.L." set. It was the second test-run of simultaneous production, and in each control room-one for Overdrive, one for "T.R.L". —separate sets of directors and producers guided cameramen and the show's hosts, known as V.J.'s, through their paces. "No one that we know has done a live stream of a different signal of an existing show." Mr. Sirulnick said. "It's a live parallel experience, one that very quickly turns into an on-demand experiment" with portions of each show archivcd and kept on the Overdrive site for fans to replay at will.

单选题Major life changes may play a role in as many as a quarter of chronic daily headache cases that arise among otherwise healthy adult men and women, study findings suggest. "Major life events may precipitate or co-occur with the development of chronic daily headaches," Dr. Ann I. Scher said. Major life changes literally shake up our world, and invite or pressure us to interact with life in new ways. To grow, we need to change our belief systems to allow for new levels of thinking and performance. Scher, of Uniformed Services University, in Bethesda, Maryland, and colleagues assessed re ports of major life changes among 206 men and women who met criteria for chronic daily headache (180 or more headache days per year). They assessed similar reports from 507 men and women with "episodic" headache (2 to 104 headache days per year). The investigators assessed changes in work, marital status, children's status, or residence; as well as deaths of family or close friends. They also inquired about self-defined "extremely stressful situations," such as financial problems, an ongoing individual illness or that of a family member, or an ongoing abusive relationship. Compared with men and women with episodic headache, men and women with chronic daily headache were more likely to have experienced major life events in the 2-year period prior to the onset of their headache condition, the researchers report in the medical journal Cephalalgia. The strongest predictor of chronic daily headache was an ongoing extremely stressful situation. The researchers also noted a higher proportion of chronic daily headache among people 40 years and older. In this group, "a change in work status was related to increased risk for chronic daily headache, while in contrast, those younger than 40 years showed a decreased risk for chronic daily headache after a job change," Scher told Reuters Health. These findings are generally consistent with prior research related to other chronic pain conditions, the investigators note. "Our finding that the relationship may be stronger for those older than 40 was an interesting, but secondary, finding that should be replicated in other samples," Scher said.
