　　It is frequently assumed that the mechanization of work has a revolutionary fect on the lives of the people who operate the new machines and on the society into which the machines have been introduced. For example, it has been suggested that the employment of women in industry took them out of the household, their traditional sphere, and fundamentally altered their position in society. In the nineteenth century, when women began to enter factories, Jules Simon, a French politician, warned that by doing so, women would give up their femininity. Friedrich Engels, however, predicted that women would be liberated from the “social, legal, and economic subordination” of the family by technological developments that made possible the recruitment of “the whole female sex into public industry.” Observers thus differed concerning the social desirability of mechanization’s fects, but they agreed that it would transform women’s lives.

　　Historians, particularly those investigating the history of women, now seriously question this assumption of transforming power. They conclude that such dramatic technological innovations as the spinning jenny (spinning jenny: n.多轴纺织机), the sewing machine, the typewriter, and the vacuum cleaner have not resulted in equally dramatic social changes in women’s economic position or in the prevailing evaluation of women’s work. The employment of young women in textile mills during the Industrial Revolution was largely an extension of an older pattern of employment of young, single women as domestics (domestic: a household servant). It was not the change in office technology, but rather the separation of secretarial work, previously seen as an apprenticeship for beginning managers, from administrative work that in the 1880’s created a new class of “dead-end” jobs, thencorth considered “women’s work.” The increase in the numbers of married women employed outside the home in the twentieth century had less to do with the mechanization of housework and an increase in leisure time for these women than it did with their own economic necessity and with high marriage rates that shrank the available pool of single women workers, previously, in many cases, the only women employers would hire.

　　Women’s work has changed considerably in the past 200 years, moving from the household to the office or the factory, and later becoming mostly white-collar instead of blue-collar work. Fundamentally, however, the conditions under which women work have changed little since bore the Industrial Revolution: the segregation of occupations by gender, lower pay for women as a group, jobs that require relatively low levels of skill and offer women little opportunity for advancement all persist, while women’s household labor remains demanding. Recent historical investigation has led to a major revision of the notion that technology is always inherently revolutionary in its fects on society. Mechanization may even have slowed any change in the traditional position of women both in the labor market and in the home.

　　(C) They employed women in only those jobs that were related to women’s traditional household work.

　　(D) They resisted technological innovations that would radically change women’s roles in the family.

　　(E) They hired women only when qualified men were not available to fill the open positions.

　　22. It can be inferred from the passage that the author most probably believes which of the following to be true concerning those historians who study the history of women?

　　(A) Their work provides insights important to those examining social phenomena affecting the lives of both sexes.

　　(B) Their work can only be used cautiously by scholars in other disciplines.

　　(C) Because they concentrate only on the role of women in the workplace, they draw more reliable conclusions than do other historians.

　　(D) While highly interesting, their work has not had an impact on most historians’ current assumptions concerning the revolutionary fect of technology in the workplace.

　　(E) They oppose the further mechanization of work, which, according to their findings, tends to perpetuate existing inequalities in society.

　　23. Which of the following best describes the function of the concluding sentence of the passage?

　　(A) It sums up the general points concerning the mechanization of work made in the passage as a whole.

　　(B) It draws a conclusion concerning the fects of the mechanization of work which goes beyond the evidence presented in the passage as a whole.

　　(C) It restates the point concerning technology made in the sentence immediately preceding it.

　　(D) It qualifies the author’s agreement with scholars who argue for a major revision in the assessment of the impact of mechanization on society.

　　(E) It suggests a compromise between two seemingly contradictory views concerning the fects of mechanization on society.

　　(This passage is excerpted from an article that was published in 1982.)

　　Warm-blooded animals have elaborate physiological controls to maintain constant body temperature (in humans, 37℃). Why then during sickness should temperature rise, apparently increasing stress on the infected organism? It has long been known that the level of serum iron in animals falls during infection. Garibaldi first suggested a relationship between fever and iron. He found that microbial synthesis of siderophores (siderophore: 含铁细胞)—substances that bind iron—in bacteria of the genus Salmonella declined at environmental temperatures above 37℃ and stopped at 40.3℃. Thus, fever would make it more difficult for an infecting bacterium to acquire iron and thus to multiply. Cold-blooded animals were used to test this hypothesis because their body temperature can be controlled in the laboratory. Kluger reported that of iguanas infected with the potentially lethal bacterium A. hydrophilia, more survived at temperatures of 42℃ than at 37℃, even though healthy animals prer the lower temperature. When animals at 42℃ were injected with an iron solution, however, mortality rates increased significantly. Research to determine whether similar phenomena occur in warm-blooded animals is sorely needed.

　　24. The passage is primarily concerned with attempts to determine

　　(A) the role of siderophores in the synthesis of serum iron

　　(B) new treatments for infections that are caused by A. hydrophilia

　　(C) the function of fever in warm-blooded animals

　　(D) the mechanisms that ensure constant body temperature

　　(E) iron utilization in cold-blooded animals

　　25. According to the passage, Garibaldi determined which of the following?

　　(A) That serum iron is produced through microbial synthesis.

　　(B) That microbial synthesis of siderophores in warm-blooded animals is more ficient at higher temperatures.

　　(C) That only iron bound to other substances can be used by bacteria.

　　(D) That there is a relationship between the synthesis of siderophores in bacteria of the genus Salmonella and environmental temperature.

　　(E) That bacteria of the genus Salmonella require iron as a nutrient.

　　26. Which of the following can be inferred about warm-blooded animals solely on the basis of information in the passage?

　　(A) The body temperatures of warm-blooded animals cannot be easily controlled in the laboratory.

　　(B) Warm-blooded animals require more iron in periods of stress than they do at other times.

　　(C) Warm-blooded animals are more comfortable at an environmental temperature of 37℃ than they are at a temperature of 42℃.

　　(D) In warm-blooded animals, bacteria are responsible for the production of siderophores, which, in turn, make iron available to the animal.

　　(E) In warm-blooded animals, infections that lead to fever are usually traceable to bacteria.

　　27. If it were to be determined that “similar phenomena occur in warm-blooded animals” (lines 21-22), which of the following, assuming each is possible, is likely to be the most fective treatment for warm-blooded animals with bacterial infections?

　　(A) Administering a medication that lowers the animals’ body temperature

　　(B) Injecting the animals with an iron solution

　　(C) Administering a medication that makes serum iron unavailable to bacteria

　　(D) Providing the animals with reduced-iron diets

　　(E) Keeping the animals in an environment with temperatures higher than 37℃
