Question

    A small piece of fish each day may keep the heart doctor away. That’s the finding of a study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed (消耗) at least an ounce (盎司) of salt water fish per day compared to those who never ate fish.

The Dutch research is one of three human studies that give strong scientific support to the long held belief that eating fish can provide health benefits, particularly to the heart.

Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year. But long before researchers have noticed that the incidence (发生率) of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption (消费) averages more than 3 ounces.

For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish.

At the start of the study, average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish than fatty fish.

During the next two decades, 78 of the men died from heart disease. The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol (胆固醇) levels.

1.We can infer from the passage that there are fewer heart disease deaths ________.

A.in highly-developed countries

B.in countries of the yellow-skin race

C.in the countries with good production of fish

D.in the countries with high consumption of fish

2.The underlined words “lean fish” (paragraph 5) mean “________”.

A.large fish B.fresh fish

C.fish that have little fat D.fish that live in salt water

3.The passage is mainly about ________.

A.the changes in people’s diet

B.the effect of fish eating on people’s health

C.the high incidence of heart disease in some countries

D.the daily fish consumption of people in different cultures

Answer

1.D

2.C

3.B

【解析】

本文是一篇说明文。主要说明了相关调查研究表明吃鱼对人们健康的有积极的影响。吃鱼多的国家，人们的心脏病死亡率相对较低。

1.推理判断题。根据第一段以及第三段的 But long before researchers have noticed that the incidence (发生率) of heart disease is lower in cultures that consume more fish than Americans do.There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption (消费) averages more than 3 ounces.（ 但是，很久以前，研究者注意到，消费掉更多鱼的国家的心脏病发病略低于美国。心脏病死亡人数在减少，例如，在格陵兰岛的爱斯基摩人中，死于心脏病的人要少一些，爱斯基摩人每天消耗大约14盎司的鱼，而日本人每天的鱼消费量平均超过3盎司）可推知，在鱼类消费量高的国家，心脏病死亡率较低。故选D。

2.词义猜测题。根据第五段的At the start of the study, average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish than fatty fish.（在研究开始时，鱼类的平均消耗量约为每天三分之二盎司，吃瘦鱼的男性比吃肥鱼的男性要多）可知，than fatty fish 省略了men eating，more…than…将前后成分进行比较，fatty意为“多脂肪的”，故lean fish与其形成对比，意为“脂肪少的鱼”。故选C。

3.主旨大意题。通读全文以及第二段的The Dutch research is one of three human studies that give strong scientific support to the long held belief that eating fish can provide health benefits, particularly to the heart.（荷兰的这项研究是三项人类研究之一，为长期以来认为吃鱼有益健康的信念提供了强有力的科学支持，尤其是对心脏有益）可知，这篇文章主要内容是相关调查研究表明吃鱼对人们健康的有积极的影响。故选B。
