9.Nowadays,cell phones are part of our lives.Many people have cell phones.They can help us easily find people anywhere at any time.However,using cell phones too often may cause cancer(癌症).It's reported that people who use a cell phone for 10years or more may get brain cancer.The suggestions below may help you reduce(减少) the risk of cancer:
When using your cell phone,try to keep it away from your body as much as possible.Don't put it on the bedside table when you go to sleep.
When you're on the cell phone,use the speaker(扬声器).In this way,you have just 1/100th of the contact(接触) with radiation you have when you hold it to your ear.An earphone is also a good idea.
Try to keep your conversations short.If you need to talk longer,use an ordinary phone instead.
Change ears when you're using your cell phone.Before putting it to your ear,wait until the person you are calling picks up the phone.
Your phone gives out radiation when you talk or send messages,but not when you're listening or getting messages.Listening more and talking less can lower the risk of cancer.
Do not use your cell phone when the signal(信号) is weak or when moving at a high speed,for example in a car or on a train.At high speeds your phone is trying to pick up signals,and this increases the radiation it gives out.
