Most of the builders and electricia
19、ns who will have to repair the houses, remake the roads and re-establish the electrical power lines will have to take on undocumented workers in order to meet their contracts. In 1996 the Immigration and Naturalisation Service (INS) conservatively estimated that Texas had over 600,000 undocumented i
20、mmigrants doing the jobs no one else wants: hauling carcasses in packing plants, picking fruit, cleaning hotel rooms, or sorting out the unspeakable damage caused by natural disasters.Mention the issue of these workers to a Texan, and he is liable to fall uncharacteristically silent. Even state legi
21、slators avoid the issue. They know that many of their constituents employ undocumented workers. They also know that the booming Texas economy is driven in part by the ready supply of cheap, diligent, illegal labour.Dallas is one magnet for undocumented workers. The citys politicians oppose INS crack
22、downs fearing they will damage the local economy and bankrupt small companies. Houston is another. There a dawn drive past some of the citys 36 informal day-labour sites shows the size of the undocumented workforce. Young Mexicans wait on the pavement, ready to jump into the back of any pick-up truc
23、k that slows down to take them. Houston police estimate that over 150,000 labourers, about 85% of them undocumented, gather every day in search of a job. It is a testament to the vitality of the Texas economy that most of them get hired usually to mix cement and shift bricks. No questions are asked,
24、 no papers signed. Most workers do not even know their employers name. They are paid in cash, around 40 dollars a day while the average American earns more than twice as much.（分数：10.00）(1).According to the passage, the presence of immigrant workers in Texas _.A. is seen as a problem by local authori
25、tiesB. is tolerated given that it helps the local economyC. can be considered evidence of the failing economyD. is a source of racial conflict（分数：2.00）A.B.C.D.(2).Some of the jobs that the illegal immigrants do as mentioned in the article include the following _.A. harvesting crops, working in hotel
26、s, repairing roads and packaging meatB. harvesting crops, managing restaurants, cleaning roads and packaging meatC. rebuilding homes, picking apples, cleaning roads and cutting meatD. repairing power lines, working in hotels, and working in parks（分数：2.00）A.B.C.D.(3).The illegal workers are _.A. hard
27、-working but costly B. lazy but cheapC. hard-working and ambitious D. hard-working and cheap（分数：2.00）A.B.C.D.(4).Which of the following was NOT stated in the passage?A.

29、mpersonal（分数：2.00）A.B.C.D.四、Passage Two(总题数：1，分数：6.00)In some society it is the custom for parents to arrange the marriages of their children. The father and mother of the bride will meet with the father and mother of the groom, and if both families are pleased with each other, an agreement will be
30、made. Often the brides and grooms will not be asked for their opinion in this matter, and sometimes they do not even meet each other until the day of the wedding. In some countries, men advertise for mail-order brides in the heal paper.Most Americans find the idea of arranged marriages difficult to
31、understand or accept. They believe that two people should marry for love, after a period of dating or courtship. During that period, the prospective marriage partners are supposed to learn enough about each other to decide whether or not they will be able to build a successful marriage. Today in Ame
32、rica, it is common for people to live together as a way of preparing for marriage. The idea of an arranged marriage seems very old fashioned indeed.But arent all marriages arranged in one way or another? In the United States marriages are seldom formally arranged, but quite a lot of informal arrangi
33、ng goes on before two people become husband and wife. People who get married are introduced to each other by friends. These friends have already decided that the two people are right for each other and arrange for them to meet. In the United States this kind of arrangement is very common. Because fr
34、iends have such great influence, their approval of a dating or mating partner is very important.Families also exert open and subtle pressures on their children to influence their choices of marriage partners. Parents often arrange dates for their own children. One parent often tells a friend a bout
35、her beautiful daughter or handsome son. Also, parents can meet the perfect marriage prospect for their son or daughter through business relationships. Since parents often assist their children financially, they feel that they have the right to help the bride and groom select where they will live, wh
36、at type of furniture they will purchase, and what their life-style will be like.To a larger extent, social class determines the choice of a marriage partner in the United States. Marriages are usually arranged between people of similar religious, ethnic, and financial back grounds. Despite what we s
37、ee in the movies, the son of a bank president rarely marries or even meets a miners daughter. Americans may not accept or understand arranged marriages, but marriages in the United States are arranged nevertheless.（分数：6.00）(1).Which of the following can be chosen as the best title of this passage?A.
38、 Americans Marriage B. Arranged MarriageC. Marriage for Love D. Perfect Marriage（分数：1.20）A.B.C.D.(2).Which of the following is not mentioned in the passage?A.

39、 will not live together before their marriage.D. Friends and parents usually play an important role in arranging marriage.（分数：1.20）A.B.C.D.(3).Most Americans deem that _.A. financial status determines the choice of a marriage partnerB. young men and women should get married as soon as they fall in l
40、oveC. arranged marriages are hardly understood and acceptedD. love plays a critical role in marriage（分数：1.20）A.B.C.D.(4).According to the passage, all of the following statements are true except that _.A. in arranged marriages, the brides and grooms never meet before their weddingB. many Americans t
41、hink the idea of arranged marriage out of dateC. all marriages are not arranged in AmericaD. a lot of informally arranged marriages exist in America（分数：1.20）A.B.C.D.(5).We can draw the conclusion that _.A. children always ask their parents for opinions about marriageB. the author thinks that in Amer
42、ica marriages still bear class characterC. it is unusual for Americans to live together as a way of preparing for marriagesD. despite the different backgrounds, people still marry in America（分数：1.20）A.B.C.D.五、Passage Three(总题数：1，分数：10.00)Every Thursday evening, I counsel a group of teenagers with se
43、rious substance abuse problems. None of the youngsters elected to see me. Typically, they were caught using drugs, or worse, by their parents or a police officer and were then referred to my clinic. To be sure, all the usual intoxicants-alcohol, marijuana and cocaine-are involved. But a new type of
44、addiction has crept into the mix, controlled prescription drugs, including painkillers. This is hardly unique to my clinic. Several studies report that since 1992, the number of 12-to 17-year-olds abusing controlled prescription drugs has tripled.One of my patients, Mary, illustrates this trend all
45、too well. Mary at 16 is a “garbage head“, meaning that she will ingest anything she thinks will give her a high. Last December, she was taken to the hospital for an overdose of alcohol, and ketamine, a chemical cousin of angel dust that doctors sometimes use to anesthetize patients and that, more co
46、mmonly, veterinarians use to sedate large animals. So where does this physically energetic teenager obtain her pills? Weeks earlier, she had an operation, a minor though uncomfortable procedure by any standards. The surgeon wrote a prescription for 80 tablets. Mary spent the next week in the addicti
47、on of the drug until her mother confiscated the last 20 tablets.At medical conferences, I hear colleagues fault parents who abuse and obtain these controlled substances but leave them easily accessible in their unlocked medicine chests where teenagers can help themselves. Other experts fault the Int
48、ernet, where al-most anyone can obtain controlled prescription drugs from offshore pharmacies with a few clicks on a home computer. None of these targets come close to the real root of the problem. Many doctors are too quick to write prescriptions for these powerful drugs.The National Center for Add
49、iction and Substance Abuse recently reported that 43.3 percent of all American doctors did not even ask patients about prescription drug abuse when taking histories; 33 percent did not regularly call or obtain records from a patients previous doctor or from other physicians before writing such prescriptions; 47.1 percent said their patients pressured them into prescribing these drugs; and only 39.1 percent had ha
