A small piece of fish each day may keep the heart doctor away. That’s the finding of a study of Dutchmen in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce 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 previous research has shown that the level 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 average 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 levels.
【小题1】The passage is mainly about .A．the high incidence of heart disease in some countriesB．the changes in people’s dietC．the daily fish consumption of people in different cultureD．the effect of fish eating on people’s health【小题2】We can infer from the passage that there are fewer heart disease deaths .A．in the countries of the yellow-skin raceB．in the countries with high consumption of fishC．in the countries with good production of fishD．in highly-developed countries【小题3】The underlined part “This relationship” may refer to the connection between and the level of heart disease.A．regular fish-eatingB．the kind of fish eatenC．the amount of fish eatenD．people of different areas【小题4】In which section of a newspaper can we read this passage?A．Ads.B．Movies.C．Health and Diet.D．Briefs.D

(答案→)D 解析：文章主要是吃鱼对人身体的影响的一个研究报告。【小题1】主旨大意题。文章主要是吃鱼对人身体的影响的一个研究报告。选D【小题2】推理题。根据第三段3,4行previous research has shown that the level of heart disease is lower in cultures that consume more fish than Americans do可知B正确。【小题3】猜测词义题。根据文章内容可知研究的是经常吃鱼与心脏病水平的关系。 选A。【小题4】文章主要是吃鱼对人身体的影响的一个研究报告。所以应该出自报纸的健康和饮食版面。选C。

这个答案应该是对的
