问题    Futurists love computers. After all,40 years ago electronic digital computers didn’t exist; today microchips as tiny as a baby’s fingernail are making all sorts of tasks faster and easier. Surely the future holds still more miracles.
   Some of the computer experiments now going on inspire exciting visions of the future. For example, scientists are working on devices that can electronically perform some sight and hearing functions, which could make life easier for the blind and deaf. They’re also working on artificial arms and legs that respond to the electric impulses produced by the human brain. Scientists hope that some day a person who’s lost an arm could still have near-normal brain control over an artificial arm.
   Video games, computerized special effects in movies, and real-life training machines now being used by the US Army are causing some people to predict new educational uses for computers. Computers could some day be used to simulate travel to other planets, to explore the ocean floor, or to look inside an atom.
   Experiments with electronic banking and shopping inspire predictions that these activities will soon be done from home computer terminals. Cars, too, might be equipped with computers to help drivers find their way around (Honda has one in an experimental car) or to communicate with home and office computers. Many people, including handicapped workers with limited ability to move around, already are working at home using computer terminals. Each terminal is connected to a system at a company’s main office. Some futurists say the day may come when few people will have to leave home to go to work -- they’ll just turn on a terminal
   A growing number of factories such as the General Motors Plant in Newark, Delaware, "hire" computerized robots to perform tasks such as spot welding. Some executives get a gleam in their eyes as they envision the spread of these "perfect workers" -- no coffee breaks, no strikes, and no vacations or sick days.
   These modern and potential computer uses are possible because of the silicon microchip.
   These chips, which have become increasingly complex since their beginning in 1959, contain a network of information pathways. Electronic impulses travel along the paths. The plans for a chip look much like a city street plan and can be as large as a football field. It can take as long as three months to complete a new chip design. Chips are used to store information, too. An entire "computer" can be put onto one chip -- called a microprocessor.
   As chips become even more complex, easier to make, and less costly, futurists predict limitless possibilities. A group of Japanese scientists is working on a new generation of computers, which they hope will be able to understand vocal instructions, talk back to their users, and automatically try out alternate solutions to a problem to come up with the best answer.
   Some people say that the humans of the future will never be without their companion -- computers. Predicting the future can be tricky, of course. In 1948 an IBM study predicted that there would never be enough demand for computers to justify going into the business!
Which of the following is NOT TRUE according to the passage?
选项 A、People will one day do shopping at home through a computer terminal.
B、In many factories computerized robots have been used because they do not cause trouble and need no breaks.
C、With the improvement of the microprocessor, more and more uses of computers will be found in the future.
D、Computers will one day be used to help drivers.
答案A
解析 细节题。本题为细节比对题。[A] 对应于第四段最后一句，但该句指的是人们可以在家通过电脑终端上班，而不是购物，因此这一选项是不正确的；[B] 与第五段两句的意思相符；[C] 与倒数第二段第一句的意思一致；[D] 与第四段第二句的意思一致。
