WITH such a large rise in mobile phone users around the world over the last 10 years,many people are worried about possible health risks. For some time,scientists have been thinking that mobile phones could lead to cancer. But so far,there is no strong evidence (證據(jù)) for this.

The Norwegian Institute of Public Health and theUK's Health Protection Agency both reported some studies last year. They said that there was no evidence found between mobile phone radiation (輻射) and cancer.

However,many heavy users of mobile phones often complain of headaches and even feeling sick. Last October,a court case inItalysaid that heavy mobile phone usage had caused brain cancer in one man. He had used a mobile phone up to six hours a day for 12 years.

But the biggest problem with research now is that it is too early to reach conclusions. Mobile phones have only been widely used since the 1990s,and cancers can take many years to develop.

There is also still a strong argument that mobile phones are a major risk for children. "In a child,the more central brain structures are going to be exposed (暴露) ”， said Dr Annie Sasco of the Institute of Public Health,speaking to the BB   C. She added, "Besides,kids have a skull (頭蓋骨) which is thinner. There is much more water in their brain. So there are many reasons that they take in more of the same radiation."

A If we want to deal with the association (社交) between boys and girls properly,here are some "dos and don'ts" for you to follow.

Keep a normal and healthy mind. Most schools and classes are made up of boys and girls. It is very natural for the boys and girls to make friends with each other. We should make as many friends as possible. We should get on with the other sex (性別) in public instead of in secret.

Don't be too nervous or too shy. If you are a shy person,you can also find a way out First of all,you can make friends with the students who have the same interest and hobby as you. As both of you have much in common,you may have much to talk about. If you keep doing like that,little by little,you will gladly find you are also as free to express yourself as others.

Don't fall into the ditch        of early love. Teenage boys and girls at a adolescence (青春期) are rich in feeling. They are easy to regard the friendship as a sign of love and fall in love with each other at an early age. In my opinion,early love is a green apple that can't be eaten. An apple won't taste sweet until it is ripe (成熟) .Boys and girls at middle schools are too young to carry the heavy duty of love. Do keep out of early love.
