完形填空

Cellphones help us easily find people anywhere at any time. However, using cellphones too often may cause cancer. (1) It’s reported that people who used a cellphone for 10 years or more were more likely to get brain cancer.

The suggestions below may help you reduce the risk(风险) of cancer:

◆When using your cellphone, try to keep it away from your body as much as possible. Don’t put it under your pillow(枕头) or on a bedside table when you sleep.

◆When you’re on the cellphone, use the speaker. In this way, you have just 1/100th of the contact with radiation you have when you hold (2) 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 cellphone. 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 text, but not when you’re listening or getting messages. (4) 多听和少说能降低癌症风险。

◆Do not use your cellphone when the signal is weak or when moving at a high speed, for example in a car or train. At high speeds your phone is trying to pick up signals, and this increases the radiation it gives out.
