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(風險) 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(枕頭) 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) 多聽和少說能降低癌癥風險。
◆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.
閱讀短文，按要求完成下面的任務。
小題1:任務一 將（1）處畫線部分翻譯成中文。
小題2:任務二 （2） Where are you not supposed to put your cellphone when you sleep?
小題3:任務三 寫出（3）處“it”所指代的內容。
