Choose the best word for each numbered blank and mark A, B, C or D on

14、 ANSWER SHEET 1. 20 A Canadian researcher has discovered that sound travels 【 21】 _ air more than one-haft kilometer an hour slower than had been believed. The discovery has surprised many engineers and scientists who learned they had been 【 22】 _ the wrong speed of sound for many years. The speed o

15、f sound in air had been 【 23】 _ to be three-hundred-thirty-one-point-two-nine meters a second. But Doctor George Wong found, 【 24】 _ accident, that the speed of sound is only three-hundred-thirty-one-point-one-three meters a second. That is a difference of about sixteen centimeters a second. Doctor

16、Wong is a member of the National Research Council of Canada. He was studying ways to 【 25】 _ exactly the sound created by microphones. One of his experiments 【 26】 _ a number he could use to find the speed of sound. He was 【 27】 _ to learn that the speed of sound was slower than scientists had thoug

It was a mathematics mistake 【 30】 _ in Nineteen-Forty-Two by physicist H-C Hardy. Doctor Wongs 【 31】 _ does not mean a big change for th

Mark your answers on ANSWER SHEET 1. 40 The food you eat does more than provide energy. It can have a dramatic effect on

25、 your bodys ability to fight off heart disease, cancer, diabetes, high blood pressure, stroke, and weak bones. With remarkable consistency, recent research has found that a diet high in plant-based foods fruits, vegetables, dried peas and beans, grains, and starchy staples such as potatoes is the bo

26、dys best weapon in thwarting many health-related problems. These foods work against so many diseases that the same healthy ingredients you might use to protect your heart or ward off cancer will also benefit your intestinal tract and bones; Scientists have recently estimated that approximately 30 to

27、 40 percent of all cancers could be averted if people ate more fruits, vegetables, and plant-based foods and minimized high-fat, high-calorie edibles that have scant nutritional value. Up to 70 percent of cancers might be eliminated if people also stopped smoking, exercised regularly, and controlled

28、 their weight. In the past, researchers had linked fat consumption with the development of cancers, but they currently believe that eating fruits, vegetables, and grains may be more important in preventing the disease than not eating fat. “The evidence about a high-fat diet and cancer seemed a lot s

29、tronger several years ago than it does now,“ says Melanie Polk, a registered dietitian and director of nutrition education at the American Institute for Cancer Research. The road to strong bones is paved with calcium-rich food. Leafy green vegetables and low-fat dairy products are excellent sources

30、of calcium, the mineral that puts stiffness into your skeletal system and keeps your bones from turning rubbery and fragile. Your body uses calcium for more than keeping your bones strong. Calcium permits cells to divide, regulates muscle contraction and relaxation, and plays an important role in th

31、e movement of protein and nutrients inside cells. If you dont absorb enough from what you eat to satisfy these requirements, your body will take it from your bones. Because your body doesnt produce this essential mineral, you must continually replenish the supply. Even though the recommended daily a

32、mount is 1,200 mg, most adults dont eat more than 500 mg. One reason may have been the perception that calcium-rich dairy products were also loaded with calories. “In the past, women, in particular, worried that dairy products were high in calories,“ says Letha Y. Griffin, M.D. , of Peachtree Orthop

33、aedics in Atlanta. “But today you can get calcium without eating any high-fat or high-calorie foods by choosing skim milk or low-fat yogurt.“ Also, low-fat dairy products contain phosphorous and magnesium and are generally fortified with vitamin D, all of which help your body absorb and use calcium.

34、 If you find it difficult to include enough calcium in your diet, ask your doctor about supplements. Theyre a potent way to get calcium as well as vitamin D and other minerals. But if you rely on pills instead of a calcium-rich diet, you wont benefit from the other nutrients that food provides. Gett

35、ing the recommended vitamin D may be easy, since your body makes the vitamin when your skin is exposed to the suns rays. 41 Which kind of food is recommended to prevent heart disease, cancer, diabetes, high blood pressure, stroke, and weak bones? （ A） Calcium-rich food （ B） Plant-based and starchy s

36、taples food （ C） High-fat, high-calorie food （ D） Vitamin D-rich food 42 The underlined word “thwart“ (Para. 1) most probably means“_“. （ A） destroy （ B） forbid （ C） cure （ D） prevent 43 _ percent of all cancers could be averted if people ate more fruits, vegetables, and plant-based foods and minimi

37、zed high-fat, high-calorie edibles. （ A） 30 40 （ B） 40 50 （ C） 50 60 （ D） 60 70 44 According to the passage, cancers may take some healthy steps other than _. （ A） stop smoking （ B） exercise regularly （ C） take non-fat diet （ D） control their weight 45 Which of the following statements is NOT true?

38、（ A） Today you can get calcium without eating any high-fat or high-calorie foods by choosing skim milk or low-fat yogurt. （ B） Calcium plays an important role in the movement of protein and nutrients inside cells. （ C） You can rely on pills instead of a calcium-rich diet to take enough calcium. （ D）

39、 If you want to absorb calcium, you should expose yourself to the suns rays. 45 A multinational corporation is a corporate enterprise, which though headquartered in one country, conducts its operations through branches that it owns or controls around the world. The organizations, mostly based in the

40、 United States, Western Europe, and Japan, have become major actors on the international stage, for some of them are wealthier than many of the countries they operate in. The less developed countries often welcome the multinationals because they are a source of investment and jobs. Yet their presenc

41、e has its drawbacks, for these organizations soon develop immense political and economic influence in the host countries. Development becomes concentrated in a few industries that are oriented to the needs of the outsiders; profits are frequently exported rather than reinvested; and local benefits g

42、o mainly to a small ruling group whose interests are tied to those of the foreigners rather than to those of their own people. The effect is to further increase export dependency and to limit the less developed countries control of their own economies. It seems that both the modernization and world-

43、system approaches may be valid in certain respects. The modernization model does help us make sense of the historical fact of industrialization and of the various internal adjustments that societies undergo during this process. The world-system model reminds us that countries do not develop in isola

44、tion. They do so in a context of fierce international political and economic competition, a competition whose outcome favors the stronger parties. Today, the less developed countries are struggling to achieve in the course of a few years the material advantages that the older industrialized nations

45、have taken generations to gain. The result is often a tug-of-war between the forces of modernization and the sentiments of tradition, with serious social disturbance as the result. The responses have taken many different forms: military overthrow by army officers determined to impose social order; f

46、undamentalist religious movements urging a return to absolute moralities and certainties of the past; nationalism as a new ideology to unite the people for the challenge of modernization. And sometimes social change takes place in a way that is not evolutionary, but revolutionary. 46 Why do the less

47、 developed countries welcome the multinationals? （ A） Because multinationals are more developed. （ B） Because multinationals bring investment and jobs. （ C） Because multinationals conduct their operations through branches. （ D） Because multinationals are wealthier. 47 Which of the following is NOT t

48、he problems brought by multinationals? （ A） They limit the host countrys control of their own economies. （ B） Profits are frequently exported rather than reinvested. （ C） Various industries develop in the host country. （ D） They increase the host countrys export dependency. 48 Which of the following

49、 is most likely to benefit from the fierce international political and economic competition? （ A） The host industries. （ B） the local people. （ C） Those stronger and richer countries. （ D） The local ruling group. 49 what does the word “tug-of-war“ probably refer to? （ A） Serious social disorder. （ B） Military overthrow by army o
