读写任务。

阅读下面的短文, 然后按照要求写一篇150词左右的英语短文。

     CHICAGO (Reuters)-Smoking not only can wrinkle(起皱纹) 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 nonfacial 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.
