单选题In a perfectly free and open market economy, the type of employer—government or private—should have little or no impact on the earnings differentials between women and men. However, if there is discrimination against one sex, it is unlikely that the degree of discrimination by government and private employers will be the same. Differences in the degree of discrimination would result in earnings differentials associated with the type of employer. Given the nature of government and private employers, it seems most likely that discrimination by private employers would be greater. Thus, one would expect that, if women are being discriminated against, government employment would have a positive effect on women's earnings as compared with their earnings from private employment. The results of a study by Fuchs support this assumption. Fuchs' results suggest that the earnings of women in an industry composed entirely of government employees would be 14.6 percent greater than the earnings of women in an industry composed exclusively of private employees, other things being equal. In addition, both Fuchs and Sanborn have suggested that the effect of discrimination by consumers on the earnings of self-employed women may be greater than the effect of either government or private employer discrimination on the earnings of women employees. To test this hypothesis, Brown selected a large sample of white male and female workers from the 1970 census and divided them into three categories: private employees, government employees, and self-employed. (Black workers were excluded from the sample to avoid picking up earnings differentials that were the result of racial disparities.) Brown's research design controlled for education, labor-force participation, mobility, motivation, and age in order to eliminate these factors as explanations of the study's results. Brown's results suggest that men and women are not treated the came by employers and consumers. For men, self-employment is the highest earnings category, with private employment next, and government lowest. For women, this order is reversed. One can infer from Brown's results that consumers discriminate against self-employed women. In addition, self-employed women may have more difficulty than men in getting good employees and may encounter discrimination from suppliers and from financial institutions. Brown's results are clearly consistent with Fuchs' argument that discrimination by consumers has a greater impact on the earnings of women than does discrimination by either government or private employers. Also, the fact the women do better working for government than for private employers implies that private employers are discriminating against women. The results do not prove that government does not discriminate against women. They do, however, demonstrate that if government is discriminating against women, its discriminating is not having as much effect on women's earnings as is discrimination in the private sector.

单选题Standard usage includes those words and expressions understood, used, and accepted by a majority of the speakers of a language in any situation regardless of the level of formality. As such, these words and expressions are well defined and listed in standard dictionaries. Colloquialisms, on the other hand, are familiar words and idioms that are understood by almost all speakers of language and used in informal speech or writing, but not considered acceptable for more formal situations. Almost all idiomatic expressions are colloquial language. Slang, however, refers to words and expressions understood by a large number of speakers but not accepted as appropriate formal usage by the majority. Colloquial expressions and even slang may be found in standard dictionaries but will be so identified. Both Colloquial usage and slang are more common in speech than in writing. Colloquial speech often passes into standard speech. Some slang also passes into standard speech, but other slang expressions enjoy momentary popularity followed by obscurity. In some cases, the majority never accepts certain slang phrases but nevertheless retains them in their collective memories. Every generation seems to require its own set of words to describe familiar objects and events. It has been pointed out by a number of linguists that three cultural conditions are necessary for the creation of a large body of slang expressions. First, the introduction and acceptance of new objects and situations in the society; second, a diverse population with a large number of subgroups; third, association among the subgroups and the majority population. Finally, it is worth noting that the terms "standard," "colloquial," and "slang" exist only as abstract labels for scholars who study language. Only a tiny number of the speakers of any language will be aware that they are using colloquial or slang expressions. Most speakers of English will, during appropriate situations, select and use all three types of expressions.

单选题{{B}}Passage 1{{/B}} Today cognitive theorists empirically study the impact of feelings on cognitive processes such as memory and judgment and also the reciprocal influence of cognition on emotion. However, evolutionary theorists view emotion as a powerful source of motivation-an internal communication that something must be done. For example, when people are threatened, they feel fear, which in turn leads them to deal with the threatening situation through either fight or flight. Emotions and drives may also operate in tandem to motivate action, as when excitement accompanies sexual arousal. From an evolutionary perspective, different emotions serve different functions. Fear facilitates flight in the face of danger; disgust prevents ingestion of potentially toxic substances such as rotting meat. An emotion that is less well understood is jealousy. Why do people become jealous in intimate sexual relationships? One series of studies tested evolutionary hypotheses about differences in the concerns men and women have about their partners' fidelity. Since females can have only a limited number of children during their lifetimes, to maximize their reproductive success they should be motivated to form relationships with males who have resources and will contribute them to their offspring. Indeed, cross-cultural evidence demonstrates that one of the main mate selection criteria used by females around the world is mate resources. From a female's point of view, then, infidelity accompanied by emotional commitment to the other woman is a major threat to resources. A man unlikely to divert re- sources from his mate and her offspring to a casual fling, but the risk increases dramatically if he becomes emotionally involved and perhaps considers switching long-term partners. Hence, a woman's jealousy would be expected to focus on her mate's emotional commitment to another female. For males, the situation is different. If a male commits himself to an exclusive relationship with a female, he must be certain that the offspring in whom he is investing are his own. Since he cannot be sure of paternity, the best he can do is to prevent his mate from copulating with any other males. In males, then, jealousy would be expected to focus less on the female's emotional commitment or resources and more on her tendency to give other males sexual access. Indeed, in species ranging from insects to humans, males take extreme measures to prevent other males from inseminating their mates. In humans, male sexual jealousy is the leading cause of homicides and of spouse battering cross-culturally.
