【正文】 ws 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 (發(fā)生率 ) faster than any other cancer in the United States. But questions has been raised about sunscreen and whether it may has opposite effect, perhaps 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— people with fair skin(白皙的膚色 ) and freckles (雀斑 ), for example— 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. 43.

So instead of 3 , kids can “fly” around in them. “Wearing Heelys is fun and cool,” said Wu Peng, a boy who wore them on his 4 day back at No. 6 Middle School in Beijing. Wu Peng said he loves the shoes so much that he wears them wherever he goes. Sometimes he even 5 his parents’ car to the supermarket on his Heelys! Other students think these are very cool, but some haven’t been so lucky with their Heelys. It’s reported that some 6 have fallen down while using these shoes, and some have been hurt. “Heelys wheels are on the heels of the shoes, so it’s easy to fall,” said Liu Rui, a doctor at the Hong Kong International Medical Clinic, Beijing. Even 7 , Liu said, “Wearing Heelys for a long time could stop young people from developing their ankles (腳踝 ) and legs.” 五、根據(jù)中文意思完成句子： 1. 我想不會下雨，不要帶傘了。 ____________________________it will rain。 leave your umbrella behind. 2. 我的手機壞了，沒有收到你的短信。 ____________________________ with my mobile phone.
