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 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 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（膽固醇）levels.

The passage is mainly about _________.

A．the high incidence of heart disease in some countries   

B．the changes in people’s diet    

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

D．the daily fish consumption of people in different cultures

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

A．in countries of the yellow-skin race

B．in highly-developed countries

C．in the countries with high consumption of fish 

D．in the countries with good production of fish

The phrase “this relationship” in paragraph 6 refers to the connection between _________ and the level of heart disease.

A．the amount of fish eaten  B．regular fish-eating  

C．the kind of fish eaten      D．people of different areas

From the passage we know the author is most probably ______.

A．a(chǎn) heart doctor   B．a(chǎn) science researcher

C．a(chǎn) supporter of healthy eating   D．a(chǎn) university student

Answer 1

【小題1】C

【小題2】C

【小題3】B

【小題4】C

解析:

【小題1】文章通過列舉數(shù)據(jù)的方式談了吃魚對人的身體健康所產(chǎn)生的影響。

【小題2】從第三段“But previous research has shown that the level of heart disease is

Lower in cultures that consume more fish than Americans do”可知C項(xiàng)為正確答案。

【小題3】從最后一段可知：在近20年里，78%的人死于心臟病。死亡率最低的是那些有規(guī)律吃

魚的人群，他們甚至比日本人及愛斯基摩人更低。結(jié)合上下文不難推斷出“這種關(guān)系”是指

有規(guī)律吃魚和心臟病發(fā)病率的關(guān)系。

【小題4】通讀全文不難看出作者至少是一位支持健康飲食的人。
