Teenagers who do not get enough of the nutrients commonly found in fruits and fish are easier to have bad lungs, coughing and wheezing (喘息).Teens who eat the least of fruit and especially vitamin C have weaker lungs compared to the others.
Teens who take in less vitamin E, found in vegetable oil and nuts, are more likely to have asthma(哮喘), Jane Bums at the Harvard School of Public Health found.
Based on these findings.Bums said that current recommended dose(一剂)of vitamin C, 85 mg a day, may not be enough for teens to have healthy lungs.Teens who eat less fruit and don't take in enough fatty acids (脂肪酸) are more likely to have asthma and the signs of breathing difficulty.
Proper amounts of fatty acids are protective, Bums said, though fish, the best source of fatty acids, is particularly unpopular with teenagers.Fatty acids are also found in some nuts as well as some green vegetables'.Smokers who avoid vitamin C will increase their chances of coughing, wheezing and developing phlegm(痰).
More than 80 percent of teens are getting their recommended doses of vitamin C - mainly from fruit drinks."I wouldn't approve of drinking them, but at least they're getting their vitamin C from somewhere," Burns said.
Burns added that there are several different ways to get the necessary nutrients."I think vitamin supplements are fine.I think adding vitamin D to orange juice is fine.But I do think there are added benefits that we don't fully understand of eating whole foods like fruits and vegetables and fish," she said.The researchers did not account for poverty and other factors that often distinguish less-healthy eaters and may explain their findings.

Dear editor,

    I am Paul , a senior English teacher in Linchuan No. 1 Middle School in Jiangxi Province , China. This letter is written to ask for your opinion.

    The other day, I met with a multiple - choice exercise. We teachers argued heatedly with each other over its answer. Unfortunately, neither side could convince the other. The sentence is to be attached at the end of the letter. There is no doubt that the reference answer C is correct. But I don’t  think it is the only answer. Personally, I do think A is also a reasonable choice in sense as well as in grammar, if the case is treated from another aspect.                                

    What puzzles me is why we should deal with so many multiple - choice exercises with not rigorous(严谨的)enough reference keys. But being a teacher, it’s very important and necessary to make it clear to students which answer is correct, which is more appropriate, and which is the best one. Regrettably, Multiple - choice test, which is a bit old - fashioned in western countries, seems to be quite popular and covers a rather high percentage in all sorts of English tests in China, especially in NMET.

    Personally speaking, I don’t think multiple - choice test form making up more than 75 percent of the total scores in college entrance examination is a very good and effective testing method. Instead, more subjective testing forms depending on one’s own thinking and his ability to use the language like key words falling, question answering, paragraph or passage summarizing, English - Chinese or Chinese - English inter - translation, etc. should be applied to English proficiency tests. Through the test forms mentioned above, students’ ability to use the language will be better developed. Consequently, more advanced and outstanding English learners could be picked out. In fact, a test paper focusing on multiple - choice test influences, in a sense, students to form their own language thinking, which hinders(阻碍)the development of their language ability as well. Do you think so?

    I am looking forward to your authoritative opinion. Thanks.

Yours sincerely,

Paul Liao
