A small piece of fish each day may keep the heart doctor away. That' s the finding of an extensive study of Dutch men 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 than those who never ate fish.
The Dutch research is one of three human studies that give strong scientific backing to the longheld 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 researchers previously 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 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, the average fish consumption was about two-thirds of an ounce each day with more men eating lean (瘦的) 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.
4. The passage is mainly about _________.
[ A ] the high incidence of heart disease in some countries
[ B ] the effect of fish eating on people ' s health
[ C] the changes in people' s diet
[D] the daily fish consumption of people in different cultures
5. Why is heart disease the most dangerous killer in the United States?
[A] Because American people drink too much spirits.
[B] Because there are a great number of fat people there.
[ C ] The author does n ' t give a definite answer.
[D] Because American people eat too much fatty fish.
6. How many lives could probably be saved each year in the United States by eating fish according to the Dutch study?
[A] 550,000. [B] 275,000.
[C] 110,000. [D] 852.

第4题,是主旨题,这文章主要讲鱼与健康的关系,文中一直用US和其他例如Japanese or Eskimos的例子来证明吃鱼可以让我们免遭受心血管疾病的关系.
第5题,是细节题,只有一句话可以推断：the incidence ( 发生率) of heart disease is lower in cultures that consume more fish than Americans do.也就是说Americans挂掉那么多人的原因是因为他们的文化和别的国家不一样,他们不太喜欢吃鱼.但是答案没有这个项,其他的都是风马牛不相及.但是C符合,definete是不确定的,文章确实没有明确指明原因,只是要我们推断.
第6题,要定位到文章的第二段的数字55000和第一段中的50％,就是说吃鱼的人要比不吃鱼的人得到心血管疾病的危险高50％.55000的美国人因不吃鱼而得到心血管疾病而挂了的人,如果吃鱼的话那么就是能救55000/2＝27500,所以选择D.这个是推断题,要计算的,有些难.
