The most useful household appliance in my home is my computer.
First,I use my computer to study.It is very convenient to search for information.
Second,the computer can be used to play games which can make me relax.
Third,I play musics on the computer and it is easy to downloud musics using the computer.
Finally,I chat with my friends by email.亲，你确定是到70个单词了？总分总形式啊，5段，急啊已经64个单词了，你自己再适当加一点。
