单选题. Aimlessness has hardly been typical of the postwar Japan whose productivity and social harmony are the envy of the United States and Europe. But increasingly the Japanese are seeing a decline of the traditional work-moral values. Ten years ago young people were hard working and saw their jobs as their primary reason for being, but now Japan has largely fulfilled its economic needs, and young people don't know where they should go next. The coming of age of the postwar baby boom and an entry of women into the male-dominated job market have limited the opportunities of teenagers who are already questioning the heavy personal sacrifices involved in climbing Japan's rigid social ladder to good schools and jobs. In a recent survey, it was found that only 24.5 percent of Japanese students were fully satisfied with school life, compared with 67.2 percent of students in the United States. In addition, far more Japanese workers expressed dissatisfaction with their jobs than did their counterparts in the ten other countries surveyed. While often praised by foreigners for its emphasis on the basics, Japanese education tends to stress test taking and mechanical learning over creativity and self-expression. "Those things that do not show up in the test scores personality, ability, courage or humanity are completely ignored," says Toshiki Kaifu, chairman of the Liberal Democratic Party education committee. "Frustration against this kind of thing leads kids to drop out and run wild." Last year Japan experienced 2,125 incidents of school violence, including 929 assaults on teachers. Amid the outcry, many conservative leaders are seeking a return to the pre-war emphasis on moral education. Last year Mitsuo Setoyama, who was then education minister, raised eyebrows when he argued that liberal reforms introduced by the American occupation authorities after World War II had weakened the "Japanese morality of respect for parents." But that may have more to do with Japanese life-styles. "In Japan," says educator Yoko Muro, "it's never a question of whether you enjoy your job and your life, but only how much you can endure." With economic growth has come centralization (集中); fully 76 percent of Japan's 119 million citizens live in cities where community and the extended family have been abandoned in favor of isolated, two-generation households. Urban Japanese have long endured length commutes (travels to and from work) and crowded living conditions, but as the old group and family values weaken, the discomfort is beginning to tell. In the past decade, the Japanese divorce rate, while still well below that the United States, has increased by more than 50 percent, and suicides have increased by nearly one-quarter.1. Compared with people a decade ago, Japanese nowadays ______.

单选题The car has reshaped our cities. It seems to offer autonomy for everyone. There is something almost delightful in the detachment from reality of advertisements showing mass-produced cars marketed as symbols of individuality and of freedom when most of their lives will be spent making short journeys on choked roads. For all the fuss made about top speeds, cornering ability and acceleration, the most useful gadgets on a modern car are those which work when you’re going very slowly: parking sensors, sound systems, and navigation apps which will show a way around upcoming traffic jams. This seems to be one of the few areas where the benefit of sharing personal information comes straight back to the sharer: because these apps know where almost all the users are, and how fast they are moving almost all the time, they can spot traffic congestion (堵塞) very quickly and suggest ways round it. The problem comes when everyone is using a navigation app which tells them to avoid everyone else using the same gadget. Traffic jams often appear where no one has enough information to avoid them. When a lucky few have access to the knowledge, they will benefit greatly. But when everyone has perfect information, traffic jams simply spread onto the side roads that seem to offer a way round them. This new congestion teaches us two things. The first is that the promises of technology will never be realised as fully as we hope; they will be limited by their unforeseen and unintended consequences. Sitting in a more comfortable car in a different traffic jam is pleasant but hardly the liberation that once seemed to be promised. The second is that self-organisation will not get us where we want to go. The efforts of millions of drivers to get ahead do not miraculously produce a situation in which everyone does better than before, but one in which almost everyone does rather worse. Central control and collective organisation can produce smoother and fairer outcomes, though even that much is never guaranteed. Similar limits can be foreseen for the much greater advances promised by self-driving cars. Last week, one operated by the taxi company Uber struck and killed a woman pushing her bicycle across a wide road in Arizona. This was the first recorded death involving a car which was supposed to be fully autonomous. Experts have said that it suggests a "catastrophic failure" of technology. Increasingly, even Silicon Valley has to acknowledge the costs of the intoxicating (令人陶醉的) hurry that characterises its culture. What traffic teaches us is that reckless and uncontrolled change is as likely to harm us as it is to benefit us, and that thoughtful regulation is necessary for a better future.
