are getting smaller all the time.
There are
several reasons（原因） why computer is useful to us.First it can store（儲藏） very,very large amount（數量）
of information（信息）.Second,the computer can operate very quickly.Third,
modern computer can be built into other kinds of machines,like radios,cars,
and planes.They can do a lot of work for us.
Soon,almost
everyone,either at home or at work,will use some kind of computer.The livesof all of us will be changed by this invention.
