2、art II Reading Comprehension (Skimming and Scanning) (15 minutes) Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions attached to the passage. For questions 1-4, mark： Y (for YES) if the statement agrees with the information given in the passage

3、; N (for NO) if the statement contradicts the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage. 1 Health Health could be defined theoretically in terms of certain measured values; for example, a person having normal body temperature, pulse and breat

4、hing rates, blood pressure, height, weight, acuity of vision, sensitivity of hearing, and other normal measurable characteristics might be termed healthy. But what does normal mean and how is it established? It is well-known that if the temperatures are taken of a large number of active, presumably

5、healthy, individuals the temperatures will all come close to 98.6F(37 ). The great preponderance of these values will fall between 98.4F and 98F. Thus health could in part be defined as having a temperature within this narrow range. Similarly, a normal range can be established for pulse, blood press

6、ure, and height. In some healthy individuals, however, the body temperature may range below 98.4F or above 98.8F. These low and high temperatures fall outside the limits defined above as normal and are instances of biological variability. Health might better be defined as the ability to function eff

7、ectively in complete harmony with ones environment. Implied in such a definition is the capability of meeting physically, emotionally, and mentally the ordinary stresses of life. In this definition health is interpreted in terms of the individuals environment. Health to the construction worker would

8、 have a dimension different from health to the bookkeeper. The healthy construction worker expects to be able to do manual labour all day, while the bookkeeper, although perfectly capable of performing his own sedentary work, would be totally incapable of such heavy labour and indeed might collapse

9、from the physical strain; yet both individuals might be termed completely healthy in terms of their own way of life. The term physical fitness, although frequently used, is also exceedingly difficult to define. In general it refers to the state of optimal maintenance of muscular strength, proper fun

10、ction of the internal organs, and youthful vigour. The champion athlete prepared to cope not only with the commonplace stresses of life but also with the unusual illustrates the concept of physical fitness. To be in good physical condition is to have the ability to swim a mile to save ones life or t

11、o slog home through snow drifts when a car breaks down in a storm. Some experts in fitness insist that the state of health requires that the individual be in prime physical condition. They prefer to divide the spectrum of health and disease into (1) health, (2) absence of disease, and (3) disease. I

12、n their view, those who are not in prime condition and are not physically fit cannot be considered as healthy merely because they have no disease. Healthy involves more than physical fitness, since it also implies mental and emotional well-being. Should the angry, frustrated, emotionally unstable pe

13、rson in excellent physical condition be called healthy? Certainly he could not be characterized as effectively functioning in complete harmony with his environment. Indeed, such an individual is incapable of good judgment and rational response. Health, then, is not merely the absence of illness or d

14、isease but involves the ability to function in harmony with ones environment and to meet the usual and sometimes unusual demands of daily life. The definitions of illness and disease are equally difficult problems. Despite the fact that these terms are often used interchangeably, illness is not to b

15、e equated with disease. A person may have a disease for many years without even being aware of its presence. Although he is diseased, he is not iii. Similarly, the diabetic person who has known disease and has received adequate insulin treatment is not ill. The cancer victim is often totally unaware

16、 of his disorder and is not ill until after long years of growth of the turnout, during which time it causes no symptoms. The term illness implies discomfort or inability to function optimally. Hence it is a subjective state of lack of well being produced by disease. Regrettably, many diseases remai

17、n submerged for long years before they produce discomfort or impair function and, thus, escape detection and possible cure. Disease, defined as any deviation from normal form and function, may be trivial if the deviation is minimal. A minor skin infection might be considered trivial, for example. On

18、 the eyelid, however, such an infection could produce considerable discomfort or illness. Any departure from the state of health, then, is a disease, whether health be measured in the theoretic terms of normal measured values or in the more pragmatic terms of ability to function effectively in harmo

19、ny with ones environment. Health is not a static condition but represents a fluid range of physical and emotional well-being continually subjected to internal and external challenges such as worry, over work, varying external temperatures, bacteria, and viruses. These constantly changing conditions

20、require the adjustment of the function of the various systems within the body. Mechanisms are continually at work to maintain a constant internal environment. The maintenance of this relatively constant internal environment is known as homeostasis (体内平衡 ). Bacteria, viruses, and other microbiologic

21、agents are obvious challenges to health. The body is able, to a considerable extent, to protect itself and adjust to challenges, and, to the extent that it is successful, the state of health is maintained. While health is often thought of as fragile and subject to many evils, it is, in fact, a rugge

22、dly guarded state protected by a host of internal mechanisms. Few machines made by man could tolerate the abuse heaped on the human body and still be capable of functioning. Some of the mechanisms vital to the maintenance of health include (1) the maintenance of the internal environment i. e. , home

23、ostasis; (2) adaptation to stress situations; (3) defense against microbiologic agents, such as bacteria and viruses; (4) repair and regeneration of damaged tissue or ceils; and (5) clothing of the blood to prevent excessive bleeding. Despite these separate considerations, the commonality of purpose

24、 the preservation and maintenance of health must not be lost sight of. Insofar as each of these mechanisms works to maintain a constant internal environment, it can be considered as a homeostatic mechanism. 2 The major functions important in the maintenance of homeostasis are fluid and electrolyte (

According to a【 B3】 _ last year by Ferguson, the British manufacturer, more than one in four VCR owners ne

So why do manufacturers keep on designing and producing VCRs that are【 B4】 _ to use if the problems are so obvious? First, the problems we notice are not obvious to【 B5】 _ mi

Finally, if manufacturers can get away with selling products that are difficult to use, it is not worth the【 B9】 _ of any one of them to make improvements.【 B8】 _ .
