A recent study shows that more and more Americans are choosing to work at home.
There are several reasons for the change. One reason is many parents want more time to be with their children at home. Another is that people want the freedom to decide for them- selves how and when to do their job. The chance to work at home lets people live wherever they wish—out in the country, perhaps. It also makes it possible for many others—disabled and other persons, new mothers-to do useful work and earn money.
About half the people who work at home operate their own business. They sell products or services. The other half works for companies. They may make things, such as clothes. Or they may do office work, such as copying letters. A smaller number work at highly skilled jobs as designers or engineers.
The revolution(革命) in computer technology is one of the main reasons for the change to working at home.
Computers are now used in almost every American workplace in offices, in factories, even on farms. Computers make it much easier and quicker to do any task that involves information: writing, counting, designing, planning, keeping records.
With computers, there is less need for people to come together to work. Computers can he linked by telephone lines with other computers far away. A worker can write a report or
add information to company records on a computer at home and then send the finished work to a computer in another city.
Americans already are using computers to do many different kinds of jobs at home. Many highly skilled workers, for example, ask their companies for the chance to work at least part of the time at home. They say they can think more clearly and be more creative in the quiet, peaceful atmosphere of their home.
Many engineers, writers and computer scientists are among those who now do at least part of their work at home, using a computer. Most of such professional workers, however, spend at least a day or two each week in the company office to discuss their work with oth- ers. Working at home is a good idea for some people in some industries. However, it does not work for everyone.
Some home workers have said their personal lives and work lives became too close. Some have said they needed to be with other people to develop new ideas. And others have said it is more difficult to get a better job with the company when you are not working in the company's office.
Lots of people hope to work at home so as to______.
A．get a higher pay
B．have enough time to stay with their children
C．have more time for rest
D．do more housework
Some of the computer experiments now going inspire imagination of the future. For example, scientists are working in devices that can electronically perform. some sight and hearing functions, which could make easier for the blind and deaf. They are also working on artificial arms and legs that respond to the electric impulses (脉冲) produced by the human brain. Scientists hope that someday a person who has lost an arm could still have near-normal brain control over an artificial arm.
Video games, computerized effects in movies, and real-life training machines now being used by the U. S. Army are causing some people to predict new educational uses for computers. Computers could someday be used to imitate travel to other planets, to explore the ocean floor or to look inside an atom.
Experiment with electronic banking and shopping inspire predictions that these activities will soon be done from home computer terminals (终端) . Cars, too, might be equipped with computers to help drivers find their way around or to communicate with home and office computers.
Many people, including handicapped (残废的) 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．Futurists and Computers

This kind of money troubles isn't strange to common families these days. In fact, it's hard to avoid news about the economy on the screen of the TV or the computers recently. It can seem a bit worry and some families are hit really hard.
For most people, the big problem is that things cost more at a time when they have less money to spend. But higher prices aren't the only problem. Many people are having a tough time making payments on some types of home loans.
Therefore, some families are cutting back on what they spend. For example, eating out less, staying home instead of going on vacation, moving to a less expensive house and so on.
However, as discouraging as things may seem now, the good news is that the economy always gets back on track after a while. Jobs may be hard to find, but the slow economy can open up new opportunities. The couple Devon babysat for might cut back on evening's out, but they could be interested in hiring her for after-school care. Perhaps it's time to sell her old toys and baby gear (设备) in the basement(地下室) or help others sell these items online if she is-good at it. She could charge them a fee to sell their old stuff(东西).
