Question

    Many studies have hinted(暗示) that alcohol, in moderation, can do a heart good. But new research suggests that moderate drinkers are no more likely than non­drinkers to have clear arteries(动脉).

The scientists looked at almost 2,000 patients who underwent CT test. Overall, there was no association between people’s drinking habits and their heart diseases. Researchers said an advantage of the new study is that it used objective measurements.

“No prior studies have assessed the relationship between alcohol consumption and the presence of heart disease,” said lead researcher Dr Julia Karady. “We could not find any relation between the presence of heart disease and alcohol consumption,” Karady said. At the same time, she added, there was no evidence that heavier drinking raised the risk of heart disease.

However, groups like the American Heart Association(AHA) warn against excessive drinking, because it can raise blood pressure and contribute to heart failure and other problems.

In general, “moderate” is defined as no more than one glass of alcohol a day for women, and no more than two a day for men. But those studies do not prove that alcohol, itself, protects the heart—in large part because alcohol also carries risks.

1.What is the advantage of the new study?

C.No prior studies have assessed the relationship.

D.There was no evidence that heavier drinking raised the risk of heart disease.

2.Why groups like the American Heart Association(AHA) are against excessive drinking?

A.Because it can raise blood pressure and contribute to heart failure and other problems.

B.Because there is some evidence that it will raise the risk of death.

C.Because it can make you die immediately.

D.Because it will lead to blindness.

3.What is “moderate” defined in the text?

A.No more than one glass of alcohol a day.

【解析】

这是一篇说明文。许多研究暗示，适量的酒精对心脏有好处。但最新研究表明，适度饮酒的人和不喝酒的人一样，动脉也不太通畅。科学家们观察了近2000名接受CT检查的患者。总的来说，人们的饮酒习惯和他们的心脏病之间没有联系。研究人员说，这项新研究的一个优点是采用了客观的测量方法。

1.细节理解题。根据第二段中“Researchers said an advantage of the new study is that it used objective measurements.”可知，研究人员说，这项新研究的一个优点是采用了客观的测量方法。故选B。

2.细节理解题。根据第四段中“However, groups like the American Heart Association(AHA) warn against excessive drinking, because it can raise blood pressure and contribute to heart failure and other problems.”可知，美国心脏协会（AHA）等团体告诫人们不要过度饮酒，因为它可以使血压升高并导致心力衰竭和其他问题。故选A。

3.细节理解题。根据第五段中“In general, “moderate” is defined as no more than one glass of alcohol a day for women, and no more than two a day for men.”可知，“适度”定义为女性每天不超过一杯酒，而男性每天不超过两杯。故选D。
