Computers, which once only remembered data, will make more decisions. Machines that today tell doctors what symptoms the patients have may soon be recommending whether or not to perform. surgery as well. Others will design new buildings after questioning buyers about their preferences. Increasingly, human thought processes and even values are being programmed into computers, according to Earl Joseph, president of a consulting firm. "Imagine machines which are smarter and more intelligent than humans and, with their embedded(植入的) initiative, can't wait to tell you about it," he says. In everyday life, the future will mean talking directly to computers without pushing buttons. Just tell a toaster, stove or other kitchen device what to do, and it will hear the message. The oven may even decide itself how long to cook the roast. Tell the television, "I want to watch Channel 12 at 8 p.m., but store the show for next week," and the job will be done. The computer will talk back, too. Already some soft-drink machines complain loudly if you don't deposit enough cash. At home, a bedside machine may someday tell you, "You forgot to turn off the basement light." Away from home, the automobile of the future will think for itself. Scientists predict that drivers will feed destinations into a computer that will then explain what route to take and even tell where parking spaces are available. A city's traffic-control system might instruct the car's computer how fast to go in heavy traffic and whether to change lanes. This passage mainly discusses ______. A．the history of computers B．the different functions of computers C．the computer in the 21st century D．scientific breakthroughs in the 21st century

In the 1980's, real estate prices soared to super inflated levels, and investors sank their money into the booming stock market. There seemed to be no end in sight for the land of the rising sun. Everything was rising, and the government, financial institutions, and individuals paid little heed to the warning signs of an imminent crash. Then, the bubble burst, and land and stock prices plunged. What is the result of the crash？ Many companies have faltered due to poor sales and bad debt, and have closed their doors. The domino effect on many financial institutions is that they must- bear an enormous number of unrecoverable loads, which have resulted when companies, depending on profits from land in vestments to repay loans, have fund themselves insolvent. Furthermore, many individual depositors, fearing a collapse of more banks and securities companies, have withdrawn their money in droves. Attempts by tile government to revitalize the sluggish and contracting economy have proven fruitless. Pump-priming measures including tax cuts and public works spending have done little to put the economy on tract again. What's more, the government's decision to increase the consumption tax from 3 to 5 percent in 1997 has had a devastating impact on consumer spending. As for the business sector, companies have tried various measures to streamline management, but other ill effects of such policies, including rising unemployment among older workers, have surfaced and have dealt a huge blow to the recovery process, Japan' s faltering economy has had an impact on other Asian countries, and some fear that the whole region will be drawn into depression. What will stem the tide of further economic collapse？ For one, Japan must stabilize its financial system and take immediate and effective measures to deal with non – performing loans. Revealing the severity of the problem to the public and foreign governments is an essential first step. A more vital solution might be to institute a permanent tax cut to stimulate consumer spending and confidence in the government' s handling of the situation. Ultimately, this will encourage domestic demand for goods and services and will be the driving force behind much of the recovery, That' s the bottom line. Of course, many more factors including deregulation will play a vital role in expediting economic stabilization and growth. Whatever the case, action must be carried out swiftly and decisively. A passive and .reticent approach to reform. and change is what has hampered any improvement so far. Other nations have encouraged Japan to step up the pace of implementing change, but Japan must make the first step . . . or else we might be witnessing the setting of this great rising sun. Japan's current economic crisis is the worst since ______. A．World War Ⅰ B．World War Ⅱ C．the Gulf War D．the Korean War

A.might as well leave B.had better to leave C.ought to have leave D.should have to leave

Dr. Jorge Yunis of the University of Minnesota Medical School in Minneapolis has found that 70 percent of oncogenes, or cancer-causing genes, are located near inherited weak points on chromosomes(染色体). Varying from individual to individual, vulnerable to chemical carcinogens(致癌剂), X rays and other cancer-inducing agents. "If a chromosome snaps apart in the immediate vicinity of an oncogene," says Yunis, "normal genetic control mechanisms could break down and the stage would be set for the formation of cancer." Younis has shown that such a sequence occurs at the beginning of numerous leukemias (白血病), lymphomas(淋巴瘤) and some tumors of the lung, colon(结肠) and breast. Yunis and other investigators have found that petroleum-based products--notably pesticides and insecticides-damage specific sites on at least two of the 23 pairs of human chromosomes that carry genetic information. Similarly, tobacco smoke tends to attack a part of another chromosome. From paragraph 1, we know that some 40 genes involving in cancer are ______. () A．harmful to the human body B．necessary to the human body C．the elements that form. cancer D．useless to the human body
