2、mprehensio(总题数:1,分数:71.00)Fish 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
3、blood lipids react positively 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 an
4、d Arctic fish a diet very high 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 tradit
5、ional Inuit diet.) Few Heart 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 hear
6、t attack deaths between 1950 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 ru
7、le out genetic or racial factors 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, wer
8、e shown to have higher blood 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
9、heart disease and arteriosclerosis 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 Simil
10、ar findings come from Japan. 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
11、average fisherman has 250 grams. 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 a
12、nd arteriosclerosis are five 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
13、 between dosage of salmon oil 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, an
14、d for those taking nine grams, concentrations dropped an average of 52 per cent.

30、hildren. But how you say it can be quite tricky. If you say to your children “Im sorry I got (37) 2with you, but.“ what follows that “but“ can render the apology ineffective; “I had a bad day“ or “your (38) 3was giving me a headache“ leaves the person who has been injured feeling that he should be (
31、39) 4for his bad behavior instead of expecting an apology. Another method by which people appear to apologize without (40) 5doing so is to say “Im sorry youre upset“; this suggests that you are somehow at (41) 6for allowing yourself to get upset by what the other person has done. Then there is the g
32、eneral, all (42) 7apology, which avoids the necessity of identifying a specific act that was (43) 8hurtful or insulting, and which the person who is should promise never to do again. (44) 9. But even when presented with examples of genuine contrition, children still need help to become aware of the
33、complexities of saying sorry. (45) 10. And that hitting a playmate over the head with a heavy toy requires an apology.

Polls (民意调查) consistently reveal t
35、hat the vast majority of Americans support moral education in the public schools, but when a specific proposal is made in a specific community, it invariably raises concerns about the content of the education. Some mistake moral education for sex education. Others fear it will be a form of religious
36、 education. Some fear moral education will be a form of strict mind control. Three basic approaches have been identified in dealing with this issue. The first approach assumes a justified content and the goal of it is to acquire this content, typically highlighting a list of values or virtues that s
37、erve as the core of the courses. It proposes to teach the code of ethical behavior, list of values or character traits etc. by a variety of methods. Traditional character education approaches tend to fall in this category. In the second approach, the individual is assumed to have an innate (固有的) ten
38、dency to develop into a moral agent; the role of education is to provide the necessary context in which this natural “flowering“ can occur. Imposing a specific content is strongly opposed by this approach. The third approach focuses on the construction of moral reasoning capacities, which are unders
39、tood to be a product of the interaction of innate qualities with ones experience in the physical and social worlds. Content is largely ignored as the focus is on reasoning structures and decision-making processes. Proposed courses do not support specific content; rather they provide the opportunity
40、to apply ones reasoning to a variety of contents. Here content is used as the medium for producing development. All three approaches have been “accused“ of being too idealistic and they tend to “accuse“ each other of the same failing. It should be noted that these positions tend to represent the wor

43、al values.(3).What does the 3rd basic approach to moral education emphasize?(分数:35.50)A.The function of physical and social worlds as catalyst.B.Developing the individual qualities.C.Giving opportunities to individuals to develop reasoning capacities.D.Leaving the individuals to develop their moral
44、values by themselves.(4).Which of the following statement is NOT true according to the passage?(分数:35.50)A.The second approach avoids providing moral content and considers content inbuilt and hidden in the individual.B.The third approach views the content of moral education as a tool in constructing
45、 moral reasoning capacities: a means to an end.C.The first approach considers the traditional values to be the priority in their education.D.The content of moral education is often challenged.(5).What does the author mean according to the last paragraph?(分数:35.50)A.Moral education will develop in se
46、parate courses set by these three approaches.B.The three approaches are not so incompatible, and they may adopt the idea of each other more or less in their own practice.C.The three approaches sound appealing, but they fail to live up to it in their practice.D.The accusative attitude towards each ot
47、her of the different approaches is not helpful with the practice of moral education.Common sense tells us that there are obvious differences between females and males: after all, biology, not culture, determines whether or not youre able to bear children. But culture and cultural myths do shape the
48、roles men and women play in our public and private relationships: we are born female and male, but we are made women and men. Sociologist distinguishes between sex and gender between ones biological identity and the conventional patterns of behavior we learn to associate with each sex. While biological sex remains a constant, the definition of “appropriate“ gender behavior varies dramatically from one cultural group or historical period to the next. The variations show up markedly in the way we dress. For example
