Question

CHICAGO (Reuters) - Smoking not only can wrinkle(起皺紋) the face and turn it yellow -- it can do the same to the whole body, researchers reported on Monday.
The study, published in the Archives of Dermatology, shows that smoking affects the skin all over the body -- even skin protected from the sun.
"We examined non-facial skin that was protected from the sun, and found that the total number of packs of cigarettes smoked per day and the total years a person has smoked were linked with the amount of skin damage a person experienced," Dr. Yolanda Helfrich of the University of Michigan, who led the study, said in a statement.
"In participants older than 65 years, smokers had significantly more fine wrinkling than nonsmokers. Similar findings were seen in participants aged 45 to 65 years," Helfrich's team added in their report.
The researchers tested 82 people, smokers and nonsmokers, taking pictures of the inner right arms. They ranged in age from 22 to 91 and half were smokers. Independent judges decided how wrinkled each person's skin was.
When skin is exposed to sunlight, notably（尤其）the face, it becomes coarse, wrinkled and discolored with a pale yellow tint, Helfrich's team wrote.
Several previous studies have found that cigarette smoking contributes to premature（過(guò)早的）skin aging as measured by facial wrinkles, the study said, but little has been done to measure the aging of skin not exposed to light.
The report did not discuss the mechanism involved but previous research has found that cigarette smoke, among other things, causes blood vessels（血管）beneath the skin to constrict（緊縮）, reducing blood supply to the skin.
Smoking can also damage the connective tissue (組織)that supports both the skin and the internal organs.

試題分析：本文講述的是美國(guó)芝加哥的一項(xiàng)健康調(diào)查發(fā)現(xiàn)抽煙的人的皮膚容易起皺紋，目的在于呼吁人們不要抽煙。
小題1:B 主旨大意題。根據(jù)文章第一段Smoking not only can wrinkle(起皺紋) the face and turn it yellow -- it can do the same to the whole body, researchers reported on Monday.
可知抽煙可以讓給人全身的皮膚起皺紋。故B正確。
小題2:D 推斷題。根據(jù)文章第四段The researchers tested 82 people, smokers and nonsmokers, taking pictures of the inner right arms. They ranged in age from 22 to 91 and half were smokers.可知調(diào)查對(duì)象的年齡跨度很大，也就是說(shuō)年齡不是問(wèn)題。故D正確。
小題3:A 細(xì)節(jié)題。根據(jù)文章倒數(shù)第二段The report did not discuss the mechanism involved but previous research has found that cigarette smoke, among other things, causes blood vessels（血管）beneath the skin to constrict（緊縮）, reducing blood supply to the skin.
可知A項(xiàng)解釋正確。
小題4:C 推理題。在本文指作者主要講述了抽煙對(duì)人們健康，尤其是皮膚的影響。目的在于呼吁人們不要抽煙。故C正確。
點(diǎn)評(píng)：本文講述的是美國(guó)芝加哥的一項(xiàng)健康調(diào)查發(fā)現(xiàn)抽煙的人的皮膚容易起皺紋。本文主旨鮮明,很容易在文中找到答案。做題時(shí)要注意文章的首段和每一段的首句或尾句，因?yàn)樗鼈兺�往就是文章的主題句。閱讀中要注意要點(diǎn)之間的關(guān)系。然后帶著問(wèn)題，再讀全文，找出答題所需要的依據(jù)，完成閱讀任務(wù)。
