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（胆固醇）levels.

The passage is mainly about _________.

A．the high incidence of heart disease in some countries   

B．the changes in people’s diet

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 heart doctor   B．a science researcher

C．a supporter of healthy eating   D．a university student

The common cold is the world's most widespread illness, which is plagues(疫病) that flesh receives.

     The most widespread fallacy(谬误) of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.

During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet, showed no increased tendency to catch colds.

In the Second World War prisoners at the notorious Auschwitz Concentration Camp(奥斯维辛集中营), naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.

    If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.

No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is relieve the symptoms.

Which of the following does not agree with the chosen passage?

   A. The Eskimos do not suffer from colds all the time.            

   B. Colds are not caused by cold.

   A. suffered a lot   B. never caught colds   C. often caught colds  D. became very strong
