问题     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 flaws and is unable to prove the exact function 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 protection of sunscreen will not last indefinitely. It should be reapplied at least every two hours when people stay outdoors for a prolonged period. After swimming, bathing, perspiring heavily, or drying 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 function, it also has the function of protecting our skin. We all know that the sun impacts collagen production in the skin, and without collagen, skin won’t naturally maintain that plump, moist, youthful, 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.
According to the text, what is not the attitude of the Writer?
选项 A、The writer has changed the prejudiced opinion on sunscreen cream.
B、The writer advises people to use sunscreen cream regularly.
C、The writer persuades the people to put the sunscreen to everyday use.
D、The writer is supporting the new findings on sunscreen cream.
答案A
解析 文章第一段表现的是人们对防晒霜的批评和猜忌，文章第二段作者提出早期发现有很多不足，对以前的错误看法加以批判。最后一段进一步提出“现在是我们改变误解的时候了”劝诫人们改变对防晒霜的理解误区。可见，作者对防晒霜自始至终是支持的态度，不存在态度的转变，所以A项说法错误。故正确答案为A。
