2、h Oil Much has been made of the benefits of oil derived from fish. It is claimed that people with a diet rich in fish oil have a greatly reduced chance of heart disease and arteriosclerosis. In addition, it has been shown conclusively that people suffering from elevated blood lipids react positively

3、 to treatment using fish oils. limits Diet and Diseases The advantages of fish oil became apparent after studies some two decades ago of the diet of the Inuit, or Erkimo, populations of Greenland. It was found that the Inuit, with their traditional diet of seal, whale and Arctic fish a diet very hig

4、h in fat suffered practically no heart disease, had near zero incidence of diabetes, and enjoyed a comparatively low rate of rheumatoid arthritis. (Interestingly, incidence of cancer, equal to that found in most other parts of the world, appeared unaffected by the traditional Inuit diet.) Few Heart

5、Attack Deaths Until the work of Dyberg and Bang in the 1970s, little attention was paid to the implications of a fish-rich diet, despite a centuries-old knowledge of Inuit customs. The two researchers noted that in one community of 1,800 people there were only three heart attack deaths between 1950

6、and 1974. To understand why, they examined the Inuits blood lipids and diet. Omega-3 fatty acids featured strongly in the bloodstream of the research subjects, directly attributable to diet. A Comparison between the Inuits in Greenland and those in Denmark In order to rule out genetic or racial fact

7、ors from their findings, Dyberg and Bang went on to compare the Greenland Inuit communities with those Inuit residing in Denmark who consumed a diet almost identical to that of the Danes. The Inuit in Denmark, particularly those who had been there for longer periods, were shown to have higher blood

8、cholesterol levels and significantly higher serum triglyceride levels than their Greenland counterparts. In fact, the levels of the Westernized Inuits matched those of the Danes themselves, who consume mainly meat, milk products and eggs. As would be expected, levels of heart disease and arterioscle

9、rosis of the Inuit well-established in Denmark were far closer to those of the Danes man those of the Greenland Inuit. The findings, according to the researchers, indicated an Omega-3 deficiency in the Danish diet compared with the Greenland diet. Findings in Japan Similar findings come from Japan.

10、A comparison of the diets of farmers and fishermen, together with an examination of health records and death rates of the two groups, has shown a link between the health of the human heart and fish oil. Whereas the average Japanese farmer has 90 grams of fish a day, the average fisherman has 250 gra

11、ms. In all other respects, their diets are similar. Correspondingly, fishermen have lower blood pressure and lower rates of heart disease and rheumatoid arthritis. This compares with the 20 grams eaten daily by the average person in the US, where rates of heart disease and arteriosclerosis are five

12、to seven times higher than in Japan. Fish Oils Effects in the Treatment of Hyperlipidaemic Patients Its high Omerga-3 content and easy digestibility make fish oil particularly useful in the treatment of hyperlipidaemic patients. Studies have shown an inverse relationship between dosage of salmon oil

13、 and plasma triglyceride concentrations. Specifically, it has been found that the consumption of three grams of salmon oil per day by such patients reduces their plasma triglyceride levels some 32 per cent. For patients given six grams, the levels fall by 41 per cent, and for those taking nine grams

14、, concentrations dropped an average of 52 per cent.

The light from a laser is called (38) 3 light because it is light that moves in only one direction. In contrast, in light, like t

As soon as the laser was developed, scientists began thinking of practical (42) 7for it. One of the earliest uses was to make extremely (43) 8measurements of distance and speed. As time

35、数：2，分数：355.00)According to a survey, which was based on the responses of over 188,000 students, todays traditional-age college freshmen are “more materialistic and less altruistic (利他主义的 )“ than at any time in the 17 years of the poll. Not surprising in these hard times, the students major objective

36、 is to be financially well off. Less important than ever is developing a meaningful philosophy of life. It follows then that today the most popular course is not literature or history but accounting. Interest in teaching, social service and the “altruistic“ fields is at a low. On the other hand, enr

37、ollment in business programs, engineering and computer science is way up. Thats no surprise either. A friend of mine (a sales representative for a chemical company) was making twice the salary of her college instructors her first year on the job - even before she completed her two-year associate deg

38、ree. While its true that we all need a career, it is equally true that our civilization has accumulated an incredible amount of knowledge in fields far removed from our own and that we are better for our understanding of these other contributions - be they scientific or artistic. It is equally true

39、that, in studying the diverse wisdom of others, we learn how to think. More important, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs. Weekly we read of unions who went on strike for higher wages, only to drive their employer out of

40、business. No company; no job. How shortsighted in the long run! But the most important argument for a broad education is that in studying the accumulated wisdom of the ages, we improve our moral sense. I saw a cartoon recently which shows a group of businessmen looking puzzled as they sit around a c

41、onference table; one of them is talking on the intercom (对讲机): “Miss Baxter, he says, “could you please send in someone who can distinguish right from wrong? From the long-term point of view, thats what education really ought to be about. （分数：177.50）(1).According to the authors observation, college

43、e influences of their instructorsB.the financial goals they seek in lifeC.their own interpretations of the coursesD.their understanding of the contributions of others(3).By saying “While its true that, be they scientific or artistic (Lines 1-3, Para. 5), the author means that_.（分数：35.50）A.business m

44、anagement should be included in educational programsB.human wisdom has accumulated at an extraordinarily high speedC.human intellectual development has reached new heightsD.the importance of a broad education should not be overlooked(4).Studying the diverse wisdom of others can_.（分数：35.50）A.create v

45、arying artistic interestsB.help people see things in their right perspectiveC.help improve connections among peopleD.regulate the behavior of modern people(5).Which of the following statements is true according to the passage?（分数：35.50）A.Businessmen absorbed in their career are narrow-minded.B.Manag

46、ers often find it hard to tell right from wrong.C.People engaged in technical jobs lead a more rewarding life.D.Career seekers should not focus on immediate interests only.How old is “old“? The answer has changed over the years. Two hundred years ago, you were old at 35. That was the average life ex

47、pectancy then. At the turn of the 19th century, as medical knowledge advanced, the average life expectancy increased to 45. In 1950, 70-year olds were really old. Today, a healthy 70-year-old is looking forward to many more active years. So, how old is old? The answer is one youve heard many times,

48、from all sorts of people. “You are as old (or young) as you feel.“ The calendar simply tells you how many years you have lived. Your body tells you how well youve lived. “Youth“, wrote an unknown author, “is not a time of life-it is a state of mind. Nobody grows old by living a number of years; people grow old by deserting (抛弃) their ideals.“ Old is a point of view. Alice Brophy, when she was with the New York City Commission for the Aging, said, “It annoys me when people say, Ge
