Cellphones help us easily find people anywhere at any time. However, using cellphones too often may cause cancer. 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 go to sleep.

◆ When you're on the cellphone, use the speaker. 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 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 (发短信), but not when you're listening     or getting messages. Listening more and talking less can lower the risk of cancer.

◆ Do not use your cellphone when the signal (信号) 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.

    There are over 37,000 known species (种) of spiders in different shapes and sizes in the world. The largest spiders live in the rain forests of South America and are known as the "bird-eating" spiders. These spiders can grow up to 28cm long and they eat small birds. The smallest spiders are from Western Samoa. These tiny spiders are less than 0.5mm long. They live in the plants that grow on mountain rocks.

    Some people like to keep spiders as pets, but most people don't like touching them. A great number of people are afraid of them, mainly because of their poison — something will cause death or harm. However, only thirty species of spiders are very dangerous to humans. Spiders provide benefits for humans by catching and eating insects, such as flies and mosquitoes (蚊子).

    Spiders are different from other animals, because they make webs to catch the small insects for food. The special silk of a spider's web is light and strong — five times stronger than steel. Some people have tried to raise spiders in order to collect their silk, but no one has ever succeeded in doing it. One reason is that it takes 670,000 spiders to produce half a kilo of silk, and all of these spiders need living insects for their food. Besides, spiders are usually solitary (独自的) animals, and need to be kept alone.

    All in all, people are amazed to learn that there are so many secrets in spiders!
