　A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk.
　Research from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.
　Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.
　But questions have been raised about sunscreen and whether it may have the opposite effect by allowing people to remain exposed to the sun longer without burning.
　The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer---are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.
　The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.

We find that bright children are rarely held back by mixed-ability teaching. On the contrary, both their knowledge and experience are enriched. We feel that there are many disadvantages in streaming（把…按能力分班）pupils. It does not take into account the fact that children develop at different rates. It can have a bad effect on both the bright and the not-so-bright child. After all, it can be quite discouraging to be at the bottom of the top grade!
　　Besides, it is rather unreal to grade people just according to their intellectual (智力的) abilities. This is only one aspect of their total personality. We are concerned to develop the abilities of all our pupils to the full, not just their academic ability. We also value personal qualities and social skills, and we find that mixed-ability teaching contributes to all these aspects of learning.
　　In our classrooms, we work in various ways. The pupils often work in groups: this gives them the opportunity to learn to co-operate, to share, and to develop leadership skills. They also learn how to cope with personal problems as well as how to think, to make decisions, to analyze and evaluate, and to communicate effectively. The pupils learn from each other as well as from the teacher.
　　Sometimes the pupils work in pairs; sometimes they work on individual tasks and assignments, and they can do this at their own speed. They also have some library, and we teach them the skills they need in order to do this effectively. And expect our pupils to do their best, not their least, and we give them every encouragement to attain this goal.

　　What is language for? Some people seem to think it's for practicing grammar rules and learning lists of words—the longer the lists，the better. That's wrong. Language is for the exchange（交流）of ideas and information. It's meaningless knowing all about a language if you can't use it freely. Many students I have met know hundreds of grammar rules, but they can't speak correctly or fluently. They are afraid of making mistakes. One shouldn't be afraid of making mistakes when speaking a foreign language. Native speakers make mistakes and break rules, too. Bernard saw once wrote, "Foreigners often speak English too correctly." But the mistakes that native speakers make are different from those that Chinese students make. They're English mistakes in the English language. And if enough native speakers break a rule, it is no longer a rule. What used to be wrong becomes right. People not only make history, they make language. But a people can only make its own language. It can't make another people's language. So Chinese students of English should pay attention to grammar, but they shouldn't overdo（做过头）it. They should put communication first.
