W: Good morning, class. Today I thought we would talk about something bright and cheerful—the sun. Can anyone tell me how you feel when it’s sunny compared to how you feel when it’s cloudy?
M: I find that it’s a lot easier to get up in the morning if it’s sunny.
W: Well, what if I told you that it would rain for weeks on end with no break.
M: I don’t think I would like that very much.
W: Most of the articles we read lately regarding the sun are discussing the negative effects of staying in the sun for too long, saying that ultraviolet radiation from the sun is a major cause of skin cancer. Although these articles are factual, the sun does have some positive side effects as well. As a matter of fact some scientists believe sunlight may reduce the risk of several types of cancer.
M: Excuse me, but many articles that I’ve read state that it can take as little as 30 minutes to get a sunburn.
W: True, but in small doses, the sun can be quite healthy for you. In fact, recent studies have found that sunlight can actually help protect you from certain types of cancer such as breast and stomach. More importantly, the sun also provides us with our main source of Vitamin D.
M: Well, I don’t need to worry about vitamins because I take multi-vitamins every day.
W: That’s great, but wouldn’t it be better if you didn’t have to take them and you were able to get vitamins in a more natural way such as food and the sun?
M: Does that mean we should spend all day in the sun without any protection?
W: No, spending roughly ten minutes per day in the sun should be enough to supply us with all the Vitamin D that we need.
1. How does the man feel when it’s sunny?
2. What does the teacher mainly want to tell her students in this class?
3. What kind of cancer may the sunlight protect us from?
4. What is the main function of sunshine when concerned with our bodies?
选项
A、Lack of vitamins is the main cause of skin cancer.
B、New research proves that sunbathing causes no problems at all.
C、The danger of the sunshine has been ignored because of its benefits.
D、Proper exposure to the sun can contribute a lot to our health.
答案
D
解析
老师在承认长时间晒太阳的害处后强调的是其益处,答案为D。说法过于绝对的选项不能选,可直接排除B。对话中提到紫外线是皮肤癌的主要致癌因素,A与录音内容不符。对话中提到近来大部分的文章都在讨论日晒的坏处,故C“由于阳光的诸多益处,它的坏处被忽略了”错误。
