A man of value never thinks of everything only in ______ of money.

A. terms                B. orders        C. times                D. sights

Only in recent years ______ begun to realize that wild dogs, kept within bounds, often do more good than harm.

The green turtle is listed as endangered by the International Union for the Conservation of Nature. Under the U．S. Endangered Species Act of 1973, the green turtle was listed as threatened except for the breeding populations in Florida and on the Pacific coast of Mexico, where it is listed as endangered.

Green turtles continue to be caught for money by humans, and the destruction and loss of nesting and foraging(觅食)sites is a serious problem. Humans have already caused the decrease of large green turtle populations, including those that once nested in Bermuda and Cayman Islands. The situation of green turtle populations is difficult to determine because of our lack of knowledge about their life cycles. The number of nests in Florida appears to be increasing, but we don't know whether this is due to an increase in the number of nests or because we have started to monitor(监控)nesting beaches more closely.

The green turtle is the largest hard­shelled sea turtle. Adults of this species commonly reach 100 cm in length and 150 kg in mass. The average size of a female nesting in Florida is 101.5 cm straight in length, with an average body mass of 136 kg.

Growth rates of green turtles have not been measured under natural conditions. Green turtles grow slowly.

In the southern Bahamas, green turtles grow from 30 to 75 cm in 17 years, and according to Bjorndal and Bolten, growth rates decrease with increasing length. Growth rates measured in green turtles from Florida and Puerto Rico fall within the range of growth rates measured in the southern Bahamas. Based on growth rate studies of wild green turtles, the researchers Balazs, Frazer and Ehrhart estimate the age of sexual maturity(成熟)can range anywhere from 20 to 50 years.

1.The main idea of the passage is to tell us________.

2.Which of the following is NOT a reason why green turtles are endangered?

3.According to the passage, the green turtle________.

4.Why is it hard for us to know the number of green turtles?

The Diet Zone: A Dangerous Place

   Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically（身体上）.

   Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale（秤）instead. All we have to do is to swallow or recognize the word “diet” in food labels.

   On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.

   The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.

   Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.

56. From Paragraph 1, we learn that ________.

A. diet products fail to bring out people’s potential

B. people have difficulty in choosing diet products

C. diet products are misleading people

D. people are fed up with diet products

57. One psychological effect of diet products is that people tend to _____.

A. try out a variety of diet foods             B. hesitate before they enjoy diet foods

C. pay attention to their own eating habits     D. watch their weight rather than their diet

58. In Paragraph 3, “gain comes without pain” probably means ______.

A. losing weight is effortless            B. it costs a lot to lose weight

C. diet products bring no pain           D. diet products are free from calories

59. Diet products indirectly harm people physically because such products ______.

A. are over-consumed               B. lack basic nutrients

C. are short of chemicals             D. provide too much energy

60. Which of the following shows the structure of the passage?

Child labor — the employment of children in industry, often against their will — has been a problem for many years. Over a hundred years ago, Charles Dickens shocked many of his readers when he described the conditions under which young children worked in British factories. The conditions Dickens described continue almost unchanged today in many parts of the world. The only difference is that today employment of children is confined（limited）to small industries and family businesses, such as hotels, restaurants and particularly farms, rather than to large factories.

Girls suffer more from child labor practices than boys. Many of them are forced to start work when they are only ten years old. Although the work they are given to do is often light, it is often harmful to the health. Recently, children as young as six years were found to be working in Asian factories, and the children were working from eight to fourteen hours a day in overcrowded and unhealthy working conditions. Sometimes a whole family group is employed, with the payment going to a parent or older relative. The children not only receive nothing or very little for their long hours of work, but also they are prevented from attending school. Therefore, when they become older they are unable to do any other kind of work.

The solution to the problem of child labor is clearly better laws to protect young children, greater supervision（监督）of industry and heavier fines for those who break the laws. Only in this way can young boys and girls be allowed to enjoy the most valuable time of their lives—childhood.
