Passage 1

[单项选择]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
A. get a higher pay
B. have enough time to stay with their children
C. have more time for rest
