The southwestern coastal region has a humid mild marine climate. 27. As a result, winter temperatures average above freezing and summers are mild. These warm western winds also carry moisture from the ocean. Inland from the coast, the winds from the Pacific meet the mountain barriers of the coastal ranges and the Rocky Mountains. 28. On some of the western slopes almost 200 inches of rain-fall each year. More than half of British Columbia is heavily forested. On mountain slopes that receive plentiful rainfall, huge Douglas firs rise in towering columns. 29. More lumber is produced from these trees than from any other kind of tree in North America.

This primitive currency is the basis of a complex monetary and trading system in the Santa Cruz Islands of the southwest Pacific. Improbable as it is, the red=feather currency fits the most rigorous definition of the term money: it serves as a means of accumulating wealth and as a universal medium of exchange in the highly diversified commerce of the islands. It is fully interchangeable, each belt having a precisely negotiable value in terms of other belts. Moreover, it has maintained its economic integrity against the recent invasion of the Australian dollar - it is still the only acceptable species for the purchase of brides, fine pigs, and certain forms of labor. The use of money is not limited to high civilization; actually many primitive peoples have devised moneys of their own. Primitive monetary systems require the same balance of supply and demand that confronts the U.S. Treasury and the Federal Reserve System; the value of the money must be carefully regulated. Lacking devices to regulate currency demand artificially, primitive societies must rely on natural or social circumstances. In the red-feather currency system, the supply of new money is regulated by availability of red feathers and by the output of the people who traditionally make the money. Old currency goes out of circulation, because it loses value as its color fades.37.Red-feather currency is one of the worlds _.A most universal types of moneyB earliest forms of moneyC most unusual forms of moneyD most complex money system38.The primitive currency described in this passage is used in _.A the entire southwest PacificB only one of the Santa Cruz IslandsC all of the Santa Cruz IslandsD both A and C39.Red-feather belts are the only acceptable species for _.A certain traditional purchasesB new red-feather beltsC any kind of commerceD accumulating wealth40.It can be inferred from the existence of this currency that _.A money is an economic sophisticationB the native of the Santa Cruz Islands are highly civilizedC with the invasion of the Australian pound, red-feather currency has maintained its valueD use of money is not the sole privilege enjoyed by the highly civilized people41.The value of any currency must be _.A regulated by artificial devicesB carefully regulatedC constantly revisedD thoughtfully devised题42-46Passage 2Forces other than damaging winds are also at work inside tornadoes(龙卷风). Sometimes, as the writhing, twisting funnel passes over a house, the walls and ceiling burst apart as if a bomb had gone off inside. This explosion is caused by the low air pressure at the center of a tornado. The pressure at the center of a tornado is usually 13 pounds per square inch. However, inside the house the air pressure is normal, about 15 pounds per square inch. The difference of 2 pounds per square inch between the inside and outside pressure may not seem like much. But suppose a tornado funnel passes over a small building that measures 20 by 10 feet. On each square inch of the building, there is 2 pounds of pressure from the inside that is not balanced by air pressure outside the building. On the ceiling, that adds up to an unbalanced pressure of 57,600 pounds. The pressure on the four walls adds up to 172,800 pounds. If windows are open m the building, some of the inside air will rush out through them. This will balance the pressure inside and outside the building. But if the windows are shut tightly, the enormous inside pressure may cause the building to burst. Unfortunately, heavy rain and hail (雹) often occur in thunderstorms that later produce tornadoes. So people frequently shut all windows to protect their property. This may cause far worse damage later. For the same reason, tornado cellars must have an air vent (通风口). Otherwise, the cellar door might be blown out when a tornado passes over it.42.Which of the following is the main topic of the passage?_A How tornadoes can be prevented.B Why tornadoes cause so much damage.C Where tornadoes are formed.D When tornadoes usually occur.43.Which of the following word is closest to funnel in sentence 2 paragraph 1?_A A tornado.B A bomb.C A house.D An explosion.44.According to the passage, tornadoes can destroy buildings because the_A force of a tornado increases the air pressure in a buildingB air pressure inside a tornado is less than the air pressure inside a buildingC weight of a tornado can crush a buildings roof when it passes overD air pressure at the center of a tornado is over 172,000 pounds45.According to the passage, what is the difference per square inch between the air pressure inside a building and the air pressure inside a tornado?_A 13 pound.B 10 pounds.C 2 pound.D 15 pounds.46.According to the passage, people close their windows to prevent damage caused by _.A TornadoesB uprooted treesC thunderstormsD bursting structures快速阅读Directions:In this section you will have 15 minutes to go over the passage quickly and answer the questions.题数:10;分数:10分;参考时间:15分0秒题47-56Passage 1The Blending of the United States Melting Pot To see the new face of the United States, go to a grocery store and look at a box of Betty Crocker-brand food products. Bettys portrait is now in its eighth incarnation(具体形象)since the first composite painting debuted(初次亮相)in 1936 with pale skin and blue eyes. Her new look is brown-eyed and dark-haired. She has a duskier complexion than her seven predecessors, with features representing an amalgam(混合物) of white, Hispanic, Indian, African and Asian ancestry. A computer created this new Betty in the mid-1990s by blending photos of 75 diverse women. That process was relatively quick, General Mills Inc., spokesmen explain. But they acknowledge that it took quite a while to spread the new image to the whole range of Betty Crocker products. The slow pace of that process itself could be a metaphor(比喻) for gradual racial and ethnic intermixing in this country. Indeed, its taking a long time for the new blended American to surface in societys consciousness. Tiger Woods, the young golf great, publicized the trend by identifying himself as Cablinasian, a mixture of Caucasian(高加索人), black, Native American and Asian. Reason for mixture For the most part, the marketplace-not government is leading the way in this evolution. Mixed-race models, particularly men, are in great demand, according to fashion industry experts. And multiracial child actors are now more likely to be tapped for television advertisements. The ad agencies that hire those models and actors are not idealistic people, Wilkins said. They are out to sell stuff, and they study trends very carefully. So, what they see is a big market out there that is reached by beautiful people who are not exactly white, or who are yearning for a melting pot America. Interracial and multiethnic fusion started after World War II and happened in the suburbs. City folk moved from their Italian, Irish, Polish or Jewish urban neighborhoods into diffuse suburban settings, and then sent their kids to large public universities, throwing them together with youngsters from other ethnic backgrounds who, nonetheless, came from families with similar lifestyles. Most people meet their potential partners either at college or when they start working, said sociologist Lee, a University of Richmond (Virginia) professor who is spending some time as a visiting scholar at Portland (Oregon) State University. David Tseng, a special assistant in the U. S. Department of Labors Pension and Welfare Benefits Administration, tells a similar story. His mother came from Ecuador; his father was the son of a Chinese diplomat in Washington. Their marriage in the late 1950s was unusual for the time. But, says Tseng, I think it helped that the people with whom they were friendly and socialized with were educated and intelligent and comfortable with people from other lands and cultures. Countervailing (相互对抗的) Forces While many forces are at work to facilitate intermarriage, others militate against it. This is particularly the case for African Americans. The growing segment of the black community that is going to college, entering the middle class and moving out to the suburbs is also following the general trend toward intermarriage. This tendency is particularly noticeable in California and in cities such as Dallas (Texas), Las Vegas (Nevada) and Phoenix (Arizona), where residential segregation has been less pronounced than in the older northeastern and midwestern U.S. cities, according to Reynolds Farley, who has studied African American residential patterns. In California, for example, among 25-to-34-year-old African Americans, 14 percent of the married black women and 32 percent of the married black men had spouses of a different race, Edmonston noted. Another countervailing force is immigration. Immigrants generally dont marry outside their racial or ethnic group. Their children do to some extent, but out-marriage really is most prevalent in the third generation. The most recent large-scale wave of immigration has produced only first-or second-generation Americans. Regardless of the real degree of racial and ethnic intermixing that goes on, the test of a blended society will be the proportion of people who identify as multiracial or multiethnic. Until now, that percentage has been small. Thats partly because people tend to assume the racial or ethnic identity of one parent often the minority parent, in the case of blacks and Hispanics. But to a large extent, that identity ha
