Question

【題目】Does a drink a day keep heart attacks away? Over the past 20years, numerous studies have found that moderate alcohol consumption, say, one or two beers, glasses of wine or cocktails daily helps to prevent coronary heart disease. Last week a report in the New England Journal of Medicine added strong new evidence in support of that theory. More importantly, the work provided the first solid indication of how alcohol works to protect the heart.

In the study, researchers from Boston's Brigham and Women's Hospital and Harvad Medical School compared the drinking habits of 340 men and women who had suffered recent heart attacks with those of healthy people of the same age and sex. The scientists found that people who sip one to three drinks a day are about half as likely to suffer heart attacks as nondrinkers are. The apparent source of the protection ： those who drank alcohol had higher blood levels of high density lipoproteins (脂蛋白），the so called good cholesterol (膽固醇），which is known to prevent heart disease.

As evidence has mounted (增長），some doctors have begun recommending a daily drink for patients of heart diseases. But most physicians are not ready to recommend a regular happy hour for everyone. The risks of teetotal ling (絕對戒酒）are nothing compared with the dangers of too much alcohol, including high blood pressure, strokes and liver troubles—not to mention violent behavior and traffic accident. Moreover, some studies suggest that even moderate drinking may increase the incidence of breast and colon cancer. Until there is evidence that the benefits of a daily dose(吸收劑量）of alcohol outweigh the risks, most people won't be able to take a doctor's prescription to the neighborhood bar or liquor store.

【2】B

【3】C

【4】D

【解析】[語篇解讀]少量喝酒，比如啤酒、雞尾酒等會減少發(fā)生心臟病的幾率。由此，醫(yī)生建議心臟病病人喝點(diǎn)酒，但是喝酒的副作用使一些病人不敢接受醫(yī)生提倡每天喝酒的建議。

【1】 由文章第一段…helps to prevent coronary heart disease. 可知答案。

【2】第二段最后兩句話:和每天喝少量酒的人相比不喝酒的人有一半可能會患心臟病，因?yàn)楹染频娜擞休^高高密度脂蛋白的血壓，這種所謂的膽固醇能阻止心臟病發(fā)生。

【3】文章最后一段中，人們對喝酒的副作用有顧慮，所以還不敢接受通過喝酒治療心臟病。

【4】文章首先提出問題，喝酒是否有利于心臟健康，下文講了人們對此的顧慮，可知文章主題是討論這個問題。
