老师评语： Part 6 Reading Comprehension (Multiple Choice) (每小题： 分) Directions: Read the following passages carefully and choose the best answer from the four choices marked A, B,

C and D.

Questions 1 to 5 are based on the following passage or dialog.

Summer is the ideal time of year for one of my favorite outdoor activities, hiking (徒步旅行). It is much more than just a great workout. You get to be outside of the confines of a gym and be together with nature. You breathe in the fresh, clean air while the city life you endured all week just fades away. You are suddenly transported somewhere else. You are suddenly in a place where you can appreciate the untouched, simplistic beauty of nature. The trees are green, the wild flowers are growing and the woods are filled with activity. Once you experience it, you're hooked. Whether hiking in the deserts of Arizona or the mountains of Alberta, you suddenly realize you are not alone and there is something much bigger at work. There is a realization that life is precious and you think deeply about your life. Another wonderful part of hiking is that you can participate at any level and it is, for the most part, free. It is a great way to escape the rat race, even during the week. If you have any problems you need to solve, hiking is really good for clearing your head and removing stress. If hiking sounds intimidating to you, it is essentially walking on a whole new level. Experts have spoken about the benefits of walking for years. Walking doesn't stress your legs as much as running and countless studies agree walking leads to weight loss and better health. It is good for your heart, reduces illness and has even been shown to enhance your thinking. So why wouldn't you want to do it? 1.

What makes hiking different from other forms of exercise?

A. It is a great workout.

B. It is a summertime activity.

C. It is an activity that slows breathing.

D. It is an exercise that is done outside. 2.

What disappears for someone who is hiking?

A. Green trees.

B. Beautiful nature.

C. City life. D. Precious things. 3.

Once you take up hiking in nature as something you do, you ________.

A. feel much bigger than before

B. love it and want to do it often

C. wish you lived outside of the city D. look for new hiking places, like Arizona 4.

How do you feel after you've begun hiking?

A. Intimidated.

B. Thoughtful.

C. Lonely. D. Free from stress. 5.

How is running different than walking?

A. Running is harder on the legs.

B. Running is better for weight loss.

C. Running is good for a person's heart.

D. Running is a cause for improved thinking. Questions 6 to 10 are based on the following passage or dialog.

Another example of the dangers of a restricted diet may be seen in the disease known as \"beri-beri\" (脚气病), which used to affect large numbers of Eastern peoples who lived mainly on rice. In the early years of the 20th century, a Dutch scientist named Eijkman was trying to discover the cause of beri-beri. At first he thought it was transmitted (传送) by a germ (细菌). He was working in a Japanese hospital, where the patients were fed on rice which had had the external husk (壳) removed from the grain, called \"white rice.\" It was thought this would be easier for weak, sick people to digest.

Eijkman thought his germ theory was confirmed when he noticed the chickens in the hospital yard, which were fed on scraps (碎片) from the patients' plates, were also showing signs of the disease. He then tried to isolate the germ he thought was causing the disease, but his experiments were interrupted by a hospital official, who ruled that the huskless polished rice was too good for chickens. The chickens should be fed cheap rice with the external covering still on the grain, called \"brown rice.\" Eijkman noticed that the chickens began to recover on the new diet. He began to consider the possibility that eating brown rice somehow prevented or cured beri-beri—even that a lack of some ingredient in the husk might be the cause of the disease. Indeed this was the case. The element needed to prevent beri-beri was shortly afterwards isolated from rice husks and is now known as Vitamin B. The white rice, though more expensive, was keeping alive the disease the hospital was trying to cure. 6.

From the context, what do you think the author mentions in the paragraph that is just before this first paragraph?

A. One example of the importance of vitamins.

B. One example of the benefits of eating healthy foods.

C. One example of the dangers of a restricted diet. D. One example of the benefits of various vitamins. 7.

The disease \"beri-beri\" ________.

A. kills large numbers of Western peoples

B. is a vitamin deficiency disease

C. is transmitted by diseased rice D. can be caught from diseased chickens 8.

The chickens Eijkman noticed in the hospital yard ________.

A. couldn't digest the huskless rice

B. proved beri-beri is transmitted by germs

C. were later cooked for the patients' food D. were suffering from vitamin deficiency 9.

Huskless, white rice ________.

A. was cheaper than brown rice

B. was less beneficial to the body than brown rice

C. was more beneficial to the body than brown rice D. cured beri-beri

10. The ingredient missing from white rice ________.

A. was Vitamin B

B. did not affect the chickens

C. was named the Eijkman vitamin

D. has never been accurately identified Questions 11 to 15 are based on the following passage or dialog.

A strict vegetarian is a person who never in his life eats anything derived from animals. The main objection to vegetarianism (素食主义) on a long-term basis is the difficulty of getting enough protein—the body-building element in food. If you have ever been without meat or other animal foods for some days or weeks (say, for religious reasons) you will have noticed that you tend to get rather weak physically. You are glad when the fast (禁食) is over and you get your reward of a delicious meat meal.

Proteins are built up from about twenty food elements called \"amino acids\" (氨基酸), which are found in greater amounts in animal protein than in vegetable protein. This means you have to eat a great deal more vegetable than animal food in order to get enough of these amino acids. A great deal of the vegetable food goes to waste in this process and from the physiological (生理学的) point of view there is not much to be said in favor of life-long vegetarianism.

The economic side of the question, though, must be considered. Vegetable food is much cheaper than animal food. However, since only a small proportion of the vegetable protein is useful for body-building purposes, a consistent vegetarian, if he is to gain the necessary 70 grams (克) of protein a day, has to consume a greater bulk of food than his digestive organs can comfortably deal with. In fairness, though, it must be pointed out that vegetarians claim they need far less than 70 grams of protein a day.

11. A strict vegetarian ________.

A. rarely eats animal products

B. sometimes eats eggs

C. never eats any animal products D. never eats protein

12. We feel weak when we go without meat and other

animal products _____.

A. because we are reducing our food amount

B. because we do not get enough protein

C. because vegetables do not contain protein D. unless we take plenty of exercise

13. Proteins are built up from ________.

A. about twenty different foods

B. about twenty different vegetables

C. various fats and sugars D. about twenty different amino acids

14. Physiologically, life-long vegetarianism may not be

good because ______.

A. it makes people very thin

B. the body must process too much waste

C. the farmer loses money

D. vitamin-deficiency diseases may result

15. One thing in favour of vegetarianism is that ________.

A. vegetable food is easier to digest

B. animal food is less expensive

C. vegetable food is cheaper

D. vegetable food contains more amino acids Questions 16 to 20 are based on the following passage or dialog.

Whether or not vegetarianism should be advocated for adults, it is definitely unsatisfactory for growing children, who need more protein than they can get from vegetable sources. A lacto-vegetarian (part milk, part vegetable) diet, which includes milk and milk products such as cheese, can, however, be satisfactory as long as enough milk and milk products are consumed.

Meat and cheese are the best sources of usable animal protein and next come milk, fish and eggs.

Slow and careful cooking of meat makes it more digestible and assists in the breaking down of the protein content by the body. When cooking vegetables, however, the vitamins, and in particular the water-soluble (溶解于水的) Vitamin C, should not be lost through over-cooking. With fruit, vitamin loss is too small to be important, because the cooking water is normally eaten along with the fruit, and natural chemicals in the fruit help to hold in the vitamin C.

Most nutrition (营养) experts today would recommend a balanced diet containing elements of all foods, largely because of our need for sufficient vitamins. Vitamins were first called \"added food factors\" when they were discovered in 1906. Most foods contain these other substances necessary for health, in addition to

carbohydrates (碳水化合物), fats, minerals and water. The most common deficiency in Western diets today is lack of vitamins. The answer is variety in food. A well-balanced

diet, having sufficient amounts of milk, fruit, vegetables, eggs, and meat, fish or chicken (i.e. any good protein source), usually provides the minimum daily requirement of all the vitamins.

16. Vegetarianism is not suitable for growing children

because they ________.

A. need more protein than vegetables can supply

B. cannot digest vegetables

C. use more energy than adults D. cannot easily digest milk and milk products

17. A lacto-vegetarian can eat _________.

A. cheese, beef, and nuts

B. carrots, milk, and rice

C. potatoes, ham, apples, and beans D. tomatoes, bacon, and oranges

18. Slow and careful cooking of meat ________.

A. preserves the vitamins

B. breaks down the vitamins

C. makes it easier to digest D. reduces the protein content

19. The reason why the vitamin loss in fruit is not

important is that ________.

A. vitamins in fruit are not removed by cooking

B. chemicals are often used in the cooking of fruit C. fruit has too few vitamins to be important to one's diet

D. the cooking water is usually eaten along with the fruit

20. Most nutrition experts today believe the food we eat

should contain ________.

A. more meat than vegetables

B. more vegetables than meat C. fruit, cereals and fish as well as meat and vegetables

D. as many different kinds of vegetables as possible Questions 21 to 25 are based on the following passage or dialog.

A department store's inputs include the land upon which the building is located; the labor of the employees; capital in the form of building, equipment and products they sell; and the management skills of the store managers. On a farm, the operation system is the transformation that occurs when a farmer's inputs (land, equipment, labor, etc.) are changed into such outputs (产出) as corn, wheat or milk. The exact process is different from industry to industry, but it is an economic phenomenon that exists in every industry. Economists refer to this change of resources into goods and services as the production function. For all operation systems, the general goal is to create some kind of value-added outputs that are worth more to consumers than just the sum of the individual inputs. To the consumers, the resulting products offer usefulness due to the form, the time, or the place they are available.

However, the process is subject to unpredictable

fluctuations (波动). Unplanned or uncontrollable influences may cause the actual output to be different from planned output. Unpredictable fluctuations can arise from external problems (fire, floods or lightning, for example) or from

internal problems that are part of the process that change them into useful goods. Variability of equipment, material imperfections, and human mistakes all affect output quality. In fact, unpredictable variations are the rule rather than the exception in the production processes; therefore, reducing variation becomes a major management task. The function of the feedback (反馈) is to provide information connection. Without some feedback of information, management personnel cannot control operations because they don't know the results of their directions.

21. What is included in a store's inputs?

A. Its equipment.

B. Its workers.

C. Its managers. D. Its departments.

22. Which of the following is a farmer's output?

A. Operation system.

B. Wheat and corn.

C. His labor. D. Transformation.

23. The production function is ________.

A. the random fluctuation that can be eliminated

B. the transformation of resources into other things

C. the goods and services that are used by people

D. the value added to items that have been transformed 24. What is the effect of unplanned or uncontrollable influences? A. Quality of output will always be reduced some. B. Actual output can be different from planned output. C. Random fluctuations can arise from external sources. D. New rules can be put in place to manage them. 25. What is the effect of not having feedback? A. Management has new tasks to accomplish. B. Management has trouble reducing variation. C. Management cannot control operations. D. Management cannot give instructions.
