Section III Reading Comprehension (60 minutes ) Part A Read the following four texts. Answer the questions below each text by choosing [A] , [B] , [C] or [D] . Mark your answers on ANSWER SHEET1. Text 1 We often hear advice from the dermatologists, ' You should keep using sunscreen cream-just to be safe'.More and more people are questioning about sunscream. Can sunscreen cream help protect me against melanomas? How safe are we in applying these chemical cocktails? Does it actually stop melanomas, the most dangerous type of skin cancer, from forming? As is known to all,sunscreen cream can protect the skin from the harmful effects of sun. The most important function of it is the prevention of skin cancer. A great number of American people like to use it. Surprisingly, this kind of cancer is increasing in incidence faster than any other cancer in the United States. It seems that sunscreen actually increases the risk of skin cancer. More and more health experts are taking a discommendable attitude to the application of sunscreen. Researchers show that the earlier finding has many fiaws and is unable to prove the exact func tion because they fail to take into account many exceptional cases. For instance, some people prefer to use sunscreen cream while going out. However, sunscreen cream users suffer from cancer more often. In fact, sunscreen cream allows people to remain exposed in the sun longer. People are likely to get skin problem under the sunshine for a long time. Besides, many people use the sunscreen cream in an inappropriate way. The sunscreen cream should be applied about half an hour before going outside, so the time is enough for the sunscreen to soak in and take effect. In fact, the pro-tection of sunscreen will not last indefinitely. It should be reapplied at least every two hours whenpeople stay outdoors for a prolonged period. After swimming, bathing, perspiring heavily, or dr-ying off with a towel or handkerchief, you had better reapply it, too. Millions of gallons of sunscreen cream are consumed each year. Only 5% of products overall met the criteria for safety and sunscreen effectiveness. Three of five brand-name products can not protect the skin from sun damage sufficiently or they contain hazardous chemicals, according to a report by Environmental Working Group ( EWG) . It is time to change our misunderstanding now. In fact, besides the sunshine-preventing func-tion, it also has the function of protecting our skin. We all know that the sun impacts collagen pro-duction in the skin, and without collagen, skin won't naturally maintain that plump, moist, youth-ful, wrinkle-free look . Without the protection of sunscreen cream, just a few minutes of daily sun exposure over the years can cause noticeable changes in skin. Sunscreen cream can protect our skin from these damaging rays, so that even if we do spend time outdoors, our face is less likely to give away our age. 41. What can we learn from the first paragraph? [ A] Sunscreen cream is essential in people's life. [ B] The dermatologists prefer to attribute the skin problems to sunshine. [ C] People agree with the dermatologists' opinion on using sunscreen cream. [D] Sunscreen cream actually increases the risk of skin cancer.
