Unemployment does not have the same dire consequences today as it did in the 1930's when most of the unemployed were primary breadwinners, when income and earnings were usually much closer to the margin of subsistence, and when there were no countervailing social programs for those failing in the labor market. Increasing affluence, the rise of families with more than one wage earner, the growing predominance of secondary earners among the unemployed, and improved social welfare protection have unquestionably mitigated the consequences of joblessness. Earnings and income data also overstate the dimensions of hardship. Among the millions with hourly earnings at or below the minimum wage level, the overwhelming majority are from multiple-earner, relatively affluent families. Most of those counted by the poverty statistics are elderly or handicapped or have family responsibilities which keep them out of the labor force, so the poverty statistics are by no means an accurate indicator of labor market pathologies. Yet there are also many ways our social statistics underestimate the degree of labor-market- related hardship. The unemployment counts exclude the millions of fully employed workers whose wages are so low that their families remain in poverty. Low wages and repeated or prolonged unemployment frequently interact to undermine the capacity for self-support. Since the number experiencing joblessness at some time during the year is several times the number unemployed in any month, those who suffer as a result of forced idleness can equal or exceed average annual unemployment, even though only a minority of the jobless in any month really suffer. For every person counted in the monthly unemployment tallies, there is another working part-time because of the inability to find full-time work, or else outside the labor force but wanting a job. Finally, income transfers in our country have always focused on the elderly, disabled, and dependent, neglecting the needs of the working poor, so that the dramatic expansion of cash and in-kind transfers does not necessarily mean that those failing in the labor market are adequately protected. As a result of such contradictory evidence, it is uncertain whether those suffering seriously as a result of thousands or the tens of millions, and, hence, whether high levels of joblessness can be tolerated or must be countered by job creation and economic stimulus. There is only one area of agreement in this debate--that the existing poverty, employment, and earnings statistics are inadequate for one of their primary applications, measuring the consequences of labor market problems. Which of the following is the principal topic of the passage？ ______ A．What causes labor market pathologies that result in suffering. B．Why income measures are imprecise in measuring degrees of poverty. C．Which of the currently used statistical procedures are the best for estimating the incidence of hardship that is due to unemployment. D．How social statistics give an unclear picture of the degree of hardship caused by tow wages and insufficient employment opportunities.

A．off B．to C．up D．over

MAN: Yes. Thank the university to allow me to come to talk to you all afternoon. The reason for my visit here is to outline a problem that female international visitors and students have been having in the Darlinghurst area. WOMAN: We all heard that for the last month or so, thieves have targeted the area snatching handbags and backpacks from unsuspected women. Why in the Darlinghurst area？ MAN: As you probably know. Darlinghurst is very popular with tourists for shopping and sightseeing and it's also a popular meeting meeting place for students. There are lots of cafes and coffee shops and unfortunately, we have had some thieves taking advantage of these conditions. WOMAN: Can you tell us about the thieves more specifically？ MAN: Sure. The thieves are young and fit. They grab the bag from the woman's shoulder or out of her hand when she's involved with something else, you know, deep in conversation or window-shopping, so they grab the bag and then run away very quickly. By the time the victims realize what's happened, the young man's out of sight and there's little hope of catching him. WOMAN: You mean the thieves usually attack female by themselves？ MAN: They used to. But now it seems they're becoming braver arid targeting women in groups. Age doesn't seem to matter to the thieves, it's just a matter of opportunity. They look for someone who isn't consciously protecting their bag and for a place with an easy getaway, you know, not too crowded. WOMAN: Are any of these thieves caught？ MAN: We've only had two of these bag-snatchers almost caught when the victims chased after them. Unfortunately, on both occasions, as soon as the women reached the thief, he threw the bag right at them and then escaped. WOMAN: Mr. Gray, can you give the students some suggestions to protect themselves from these brazen thieves？ MAN: Yeah. We don't encourage you to chase these thieves because we don't want to see anyone get hurt. So, what can you do？ Well, unfortunately, not much but we are asking that you be aware of this danger. If possible, hang onto your bags carefully and never leave your bags on the ground at one of the many cafes when you have a coffee or a meal and don't leave it on a chair or table-top even if you think it is in your sight. We also caution you about carrying anything too valuable in your bags. It seems like the thieves arc not only after cash. They've been using credit cards illegally on the Internet m purchase goods or access pornographic sites. So it is vital that you keep your credit card details and report to the police if it is stolen. Questions: 19.What is the problem that Mr. Gray describes to the students？ 20.Why is it difficult to chase the thieves？ 21.How many thieves have the police caught？ 22.Which of the following does Mr. Gray suggest the students to do？ (39) A．Women being robbed. B．Thieves stealing bags from international tourists. C．Darlinghurst residents being robbed. D．Burglaries happening in Darlinghurst.

A．who B．whose C．whom D．that

With regard to this, perhaps their most traditionally sanctioned task, colleges and universities today find themselves in a serious bind generally. On the one hand, there is the American commitment, entered into especially since World War II, to provide higher education for all young people who can profit from it. The result of the commitment has been a dramatic rise in enrollments in our universities, coupled with a radical shift from the private to the public sector of higher education. On the other hand, there are serious and continuing limitations on the resources available for higher education. While higher education has become a great "growth industry", it is also simultaneously a tremendous drain on the resources of the nation. With the vast increase in enrollment and the shift in priorities away from education in state and federal budgets, there is in most of our public institutions a significant decrease in per capita outlay for their students. One crucial aspect of this drain on resources lies in the persistent shortage of trained faculty, which has led, in turn, to a declining standard of competence in instruction. Intensifying these difficulties is, as indicated above, the concern with research, with its competing claims on resources and the attention of the faculty. In addition, there is a strong tendency for the institutions' organization and functioning to conform. to the demands of research rather thorn those of teaching. According to the author, ______ is the most important function of institutions of higher education. A．creating new knowledge B．providing solutions to social problems C．making experts on sophisticated industries out of their students D．preparing their students to transmit inherited knowledge

When our population is so small that all our labor can be engaged in the group represented by A, productivity of labor (and therefore wages) will be at their maximum. When our population increases so that some of the labor will have to be set to work in group B, the wages of all labor must decline to the level of the productivity in that group. But no employer, without government aid, will yet be able to afford to hire labor to exploit the opportunities represented by C and D, unless there is a further increase in population. But suppose that the political party in power holds the belief that we should produce every thing that we consume, that the opportunities represented by C and D should be exploited. The commodities that the industries composing C and D will produce have been hitherto obtained from abroad in exchange for commodities produced by A and B. The government now renders this difficulty by placing high duties upon the former class of commodities. This meads that workers in A and B must pay higher prices for what they buy, but do not receive higher prices for what they sell. After the duty has gone into effect and the prices of commodities that can be produced by C and D have risen sufficiently, enterprisers will be able to hire labor at the wages prevailing in A and B, and establish industries in C and D. So far as the remaining laborers in A and B buy the products of C and D, the difference between the price which they pay for those products and the price that they would pay if they were permitted to import those products duty-free is a tax paid not to the government, but to the producers in C and D, to enable the latter to remain in business. It is an uncompensated deduction from the natural earnings of the laborers in A and B. Nor are the workers in C and D paid as much, estimated in purchasing power, as they would have received if they had been allowed to remain in A and B under the earlier conditions. When C and D are established, workers in these industries______. A．receive higher wages than do the workers in A and B B．receive lower wages than do the workers in A and B C．are not affected so adversely by the levying of duties as are workers in A and B D．receive wages equal to those workers in A and B
