我国家用电灯、电视机的电压为______，一节干电池的电压为______，对人体的安全电压应______，合______kV．日光灯工作电流约为0.15A，合为______mA．

答案

我国家庭电路的电压是220V，家用电器的额定电压是220V，一节干电池的电压是1.5V，人体安全电压不高于36V．

36V=36×1V=36×0.001kV=0.036kV，

0.15A=0.15×1A=0.15×1000mA=150mA．

故答案为：220V；1.5V；不高于36V；0.036；150．

Dear Wang Ping,

     Your problem is common one among middle school students. Maybe the following advices can help you.

First in all, believe in yourself. Your greatest problem is that you lack self-confidence. The first thing you

must do is to smile at your classmates. One smile speaks loud about your wish to make friends than any word.

Your smile will show that you are friendly to him. Next, trying talking with a student who is as shy as you or

who share the same interest as you. You can discuss your studies with a classmate but you can also talk about

your hobbies as well. Unless anyone is in trouble, you should be ready to help him or her. Once you have

confidence, you can make as many friends as possibly.

                                                                                                                                                  Yours,

                                                                                                                                                   Lily
