25、o the sight of American astronauts in tip-top condition, with fair hair, crew-cuts, good teeth, an uncomplicated sense of humour and a severely limited non-technical vocabulary. What marks out an astronaut from his earthbound fellow human beings is something of a difficult problem. Should you wish t
26、o interview him, you must apply beforehand, and you must be prepared for a longish wait, even if your application meets with success. It is. in any case, out of the question to interview an astronaut about his family life or personal activities, because all the astronauts have contracts with an Amer
27、ican magazine under conditions forbidding any unauthorized disclosures about their private lives. Certain obvious qualifies are needed. Anyone who would be a spaceman must be in perfect health, must have powers of concentration(since work inside a spacecraft is exceptionally demanding)and must have
28、considerable courage. Again, space-work calls for dedication. Courage and dedication are particularly essential. In the well-known case of the Challenger seven crew members lost their lives in space because of the faulty equipment in the shuttle. Another must be outstanding scientific expertise. It
29、goes without saying that they all have to have professional aeronautical qualifications and experience. A striking feature of the astronauts is their ages. For the younger man, in his twenties, say, space is out. Only one of the fifty men working for NASA in 1970 was under 30. The oldest astronaut t
30、o date is Alan Shepard, Americas first man in space, who, at nearly fifty, was also the man who captained Apollo 13. The average age is the late thirties. The crew members of Apollo 11 were all born well before the Second World War. In 1986 the Challenger astronauts had an average age of 39. The ran
31、ge was from 35 to 46. In a society where marital continuity is not always exhibited, the astronautsrecord in this respect hits you in the eye. Of all the married men in NASA group, only two or three are divorced from their wives. Mind you. it is hard to tell whether something in the basic character
32、of an astronaut encourages fidelity or whether the selection process demands that a candidate should be happily married. The NASA astronauts live in unattractive small communities dotted here and there around the base in Texas. You would expect them to find their friends from among their professiona
33、l associates, but this is not the case. Rather, they prefer to make friends with the normal folk in their districts. Astronauts, like everybody else, must get fed up with talking shop all the time, and whereas they are indeed an elite, their daily life outside work should be as normal as possible, i
34、f only for the sake of their families. As for the astronautspolitical leanings, they seem to be towards the right. This may be due to the fact that a large proportion of the astronauts have a military background. On the other hand, it could be just coincidence. （分数：5.00）(1).Details of the private li
35、fe of an astronaut are hard to come by, because they are_.（分数：1.00）A.his own business and privacyB.secrets as far as interviews are concernedC.the property of an American magazineD.the first-rate national confidential information(2).To audience, the typical American astronaut_.（分数：1.00）A.has a limit

38、from among their work.D.There is no younger man in his twenties in the spaceship.BText 2/BText 2Defenders of special protective labor legislation for women often maintain that eliminating such laws would destroy the fruits of a century-long struggle for the protection of women workers. Even a brief
39、examination of the historic practice of courts and employers would show that the fruit of such laws has been bitter; they are, in practice, more of a curse than a blessing. Sex-defined protective laws have often been based on stereotypical assumptions concerning womens needs and abilities, and emplo
40、yers have frequently used them as legal excuses for discriminating against women. After the Second World War, for example, businesses and government sought to persuade women to vacate jobs in factories, thus making room in the labor force for returning veterans. The revival or passage of state laws
41、limiting the daily or weekly work hours of women conveniently accomplished this. Employers had only to declare that overtime hours were a necessary condition of employment or promotion in their factory, and women could be quite legally fired, refused jobs, or kept at low wage levels, all in the name
42、 of“protecting”their health. By validating such laws when they are challenged by lawsuits, the courts have colluded over the years in establishing different, 1ess advantageous employment terms for women than for men, thus reducing womens competitiveness on the job market. At the same time, even the
43、most well-intentioned lawmakers, courts, and employers have often been blind to the real needs of women. The lawmakers and the courts continue to permit employers to offer employee health insurance plans that cover all known human medical disabilities except those relating to pregnancy and childbirt
44、h. Finally, labor laws protecting only special groups are often ineffective at protecting the workers who are actually in the workplace. Some chemicals, for example, pose reproductive risks for women of childbearing years；manufacturers using the chemicals comply with laws protecting women against th
45、ese hazards by refusing to hire them. Thus the sex-defined legislation protects the hypothetical female worker, but has no effect whatever on the safety of any actual employee. The health risks to male employees in such industries cannot be negligible. since chemicals toxic enough to cause birth def
46、ects in fetuses or sterility in women are presumably harmful to the human metabolism. Protective laws aimed at changing production materials or techniques in order to reduce such hazards would benefit all employees without discriminating against any. In sum, protective labor laws for women are discr
47、iminatory and do not meet their intended purpose. Legislators should recognize that women are in the work force to stay, and that their needsgood health care. a decent wage,and a safe workplaceare the needs of all workers. Laws that ignore these facts violate womens rights for equal protection in employment. （分数：5.00）(1).According to the author, which of the following resulted from the passage or
