23、、Text 1(总题数：1，分数：10.00)The American party system is a two-party system which is unlikely to become anything else. It is not just that the two-party polarization has the weight of tradition behind it but also that the two-party polarization is built into our constitutional and legal system. Our entir
24、e electoral arrangements, the absence of proportional representation, the exorbitant cost of political campaigns, the legal difficulties in getting on and staying on the ballot in many states-all these things work against the rise of minor parties.Also the single member legislative district, the div
25、ision of power between the nation and the states, the method of electing a president with the winner itself, work to keep power in the hands of the two major parties. Major parties (like the Federalists and the Whigs) have broken up and been replaced as new parties have emerged in the past. But no m
26、inor party has ever gradually risen to achieve the stature of a major party, and no third party has lasted very long in any prominent capacity.All this is not to say that third parties do not have a function in the American system. However, their function is largely that of pressure groups, and in t
27、his respect they are a curious combination of European special-interest parties and American interest groups. They have at various times been useful in bringing to the fore the interests of neglected groups in the public at large. The Populist party of 1890s as was a notable case in point.What happe
28、ns characteristically, however, is that as soon as third parties begin to make their mark, one or both of the major parties appropriates enough of their principles or program to absorb the discontent on which they were flourishing. For this reason it has been said that third parties are like bees: o
29、nce they have stung they must die.（分数：10.00）(1).The word “exorbitant“ (Line 4, Para. 1) means “_“.（分数：2.00）A.not expensiveB.fairly expensiveC.too expensiveD.too cheap(2).According to the author, under the two-party system, the two parties will _ .（分数：2.00）A.hold opposing stands in each and every iss
30、ueB.cooperate with each other to hold the power in their handsC.insult each other in politics and in lifeD.respect each other on an equal basis(3).In this passage, the example of Populists is used to illustrate _ .（分数：2.00）A.the function of two-party system in United StatesB.the function of third pa
31、rty to bring to prominence the interest of neglected groupC.the disadvantage of the third party in the United StatesD.the rise of the third party in the United States(4).When a third party begins to catch peoples attention, the major parties will _ .（分数：2.00）A.interfere with the third partys gistB.e
32、lbow it out of the political stageC.eradicate it by assimilating its different doctrinesD.share some interests to the third party(5).It can be inferred from this passage that _ .（分数：2.00）A.traditional power supports the two-party system in the United StatesB.none of the major parties has broken up i

35、is is a deeply felt mission.“Ive walked a very fine line between the abled and disabled worlds all my life,“ says Bethune, a former soloist with the New York City Ballet who starred on Broadway in Tommy Tunes production of Grand Hotel. Born and raised in New York City, Bethune, 47, started formal ba
36、llet training at age 6 with legendary choreographer George Balanchine. But during adolescence, a host of medical problems mined her chances of becoming a prima ballerina. But she ignored them and her pain and continued to dance. Faced with all sorts of difficulties, she never gave up. By the time sh
37、e was 34, Bethune had went gone two hip replacements.Bethune, who has been married for 18 years to a former dancer, started Infinite Dreams in southern California in 1983. “Dance is spiritual,“ she says. “And these childrens spirits are not disabled.“ Funded through grants and private donations, the
38、 group offers hour-long weekly sessions in schools and performs at arts festivals throughout the year.“Participation, not perfection, is emphasized,“ notes Bethune, who is currently trying to make her program available nationally. Adjustments to the dance steps are made as needed. Russell Bartel, 14
39、, a star student with spina bifida and little feeling in his lower legs, pirouettes not by turning on his toes but by spinning on his back. “What we try to make clear,“ Bethune says, “is that their individual version of any step is valid. Thats their dance.“From that understanding often springs a ne

44、.Disapproval.D.Doubtful.九、Text 3(总题数：1，分数：10.00)All of us have read thrilling stories in which the hero had only a limited and specified time to live. Sometimes it was as long as a year, sometimes as short as 24 hours. But always we were interested in discovering just how the doomed hero chose to sp
45、end his last days or his last hours. I speak, of course, of free men who have a choice, not condemned criminals whose sphere of activities is strictly delimited.Such stories set us thinking, wondering what we should do under similar circumstances. What events, what experiences, what associations sho
46、uld we crowd into those last hours as mortal beings, what regrets?Sometimes I have thought it would be an excellent role to live each day as if we should die tomorrow. Such an attitude would emphasize sharply the values of life. We should live each day with gentleness, vigor and a keenness of apprec
47、iation which are often lost when time stretches before us in the constant panorama of more days and months and years to come. There are those, of course, who would adopt the Epicurean motto of “Eat, drink, and be merry“. But most people would be chastened by the certainty of impending death.In stori
48、es the doomed hero is usually saved at the last minute by some stroke of fortune, but almost always his sense of values is changed. He becomes more appreciative of the meaning of life and its permanent spiritual values. It has often been noted that those who live, or have lived, in the shadow of dea
49、th bring a mellow sweetness to everything they do.Most of us, however, take life for granted. We know that one day we must die, but usually we picture that day as far in the future. When we are in buoyant health, death is all but unimaginable. We seldom think of it. The days stretch out in an endless vista. So we go about our petty tasks, hardly aware of our listless attitude toward life.（分数：10.00）(1).Why is the author talking about those examples in paragraph 1?（分数：2.00）A.To prove that life is full of twist and turns.B.To raise a quest
