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.
The word "met" in Paragraph Three, Line Two probably refers to
选项
A、see
B、discover
C、reach
D、act
答案
C
解析
根据第三段后半部分的内容“Three of five brand-name products can not protect the skin from sun damage sufficiently or they contain hazardous chemicals…”可知,五分之三的知名产品不能有效保护皮肤免受阳光的伤害,或者含有有害的化学物质,所以这些产品是不合格的,由此可推断met the criteria在这里表示的意思是“符合、达到标准”,故正确答案为C选项。
