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 nuinber-one killer in the United States, with more than 550,000 deaths oc- curring 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.

[ 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
54. 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.

Being assertive ( 过分自信) is being able to communicate with other people clearly. If you felt that you had expressed what was important to you and allowed the oilier person to respond in their own way then, regardless of the final outcome, you behaved assertively. It is important to remember that being assertive refers to a way of coping with confrontations ( 对抗)。 It does not mean getting your own way every time or winning some battle of wits against another person. In practice assertive behaviour is usually most likely to produce a result which is generally acceptable to all concerned, without anyone feeling that they have been unfairly treated.
