In fact, the Chinese had business relations with Hawaii prior to relations with
8、the mainland when Hawaii was not yet part of the United States. But United States investments controlled the capital of Hawaii at that time. In 1788, a ship sailed from Guangzhou to Hawaii. Most of the crewmen were Chinese. They were considered the pioneers of Hawaii. The Immigration Commission repo
9、rted that the first Chinese arrived in the United States in 1820, eight in 1830 and seven hundred and eighty in 1850. The Chinese population gradually increased and reached 64,199 in 1870. BFor many years it was common in the United States to associate Chinese Americans with restaurants and laundrie
10、s. People did not realize that the Chinese had been driven into these occupations by the prejudice and discrimination that faced them in this country. CThe first Chinese to reach the mainland United States came during the California Gold Rush of 1849. Like most of the other people there, they had co
11、me to search for gold. In that largely unoccupied land, the men staked a claim for themselves by placing markers in the ground. However, either because the Chinese were so different from the others or because they worked so patiently that they sometimes succeeded in turning a seemingly worthless min
12、ing claim into a profitable one, they became the scapegoats of their envious competitors. They were harassed in many ways. Often they were prevented from working their claims; some localities even passed regulations forbidding them to own claims. DThe Chinese therefore started to seek out other ways
13、 of earning a living. Some of them began to do the laundry for the white miners; others set up small restaurants.(There were almost no women in California in those days, and the Chinese filled a real need by doing this “womans work“.)Some went to work as farmhands or as fishermen. EIn the early 1860
14、s many more Chinese arrived in California. This time the men were imported as work crews to construct the first transcontinental railroad. They were sorely needed because the work was so strenuous and dangerous, and it was carried on in such a remote part of the country that the railroad company cou
15、ld not find other laborers for the job. As in the case of their predecessors, these Chinese were almost all males; and like them, too, they encountered a great deal of prejudice. FThe hostility grew especially strong after the railroad project was complete, and the imported laborers returned to Cali
16、fornia thousands of them, all out of work. Because there were so many more of them this time, these Chinese drew even more attention than the earlier group did. They were so very different in every respect: in their physical appearance, including a long “pigtail“ at the back of their otherwise shave
17、d heads; in the strange, non-Western clothes they wore; in their speech(few had learned English since they planned to go back to China); and in their religion. They were contemptuously called “heathen Chinese“ because there were many sacred images in their houses of worship. GWhen times were hard, t
18、hey were blamed for working for lower wages and taking jobs away from white men, who were in many cases recent immigrants themselves. Anti-Chinese riots broke out in several cities, culminating in arson and bloodshed. Chinese were barred from using the courts and also from becoming American citizens
19、. Californians began to demand that no more Chinese be permitted to enter their state. Finally, in 1882, they persuaded Congress to pass the Chinese Exclusion Act, which stopped the immigration of Chinese laborers. Many Chinese returned to their homeland, and their numbers declined sharply in the ea
20、rly part of this century. HHowever, during the World War n, when China was an ally of the United States, the Exclusion laws were ended; a small number of Chinese were allowed to immigrate each year, and Chinese could become American citizens. In 1965, in a general revision of our immigration laws, m
21、any more Chinese were permitted to settle here, as discrimination against Asian immigration was abolished. IFrom the start, the Chinese had lived apart in their own separate neighborhoods, which came to be known as “Chinatowns“. In each of them the residents organized an unofficial government to mak
22、e rules for the community and to settle disputes. Unable to find jobs on the outside, many went into business for themselves primarily to serve their own neighborhood. As for laundries and restaurants, some of them soon spread to other parts of the city, since such services continued to be in demand
23、 among non-Chinese, too. To this day, certain Chinatowns, especially those of San Francisco and New York, are busy, thriving communities, which have become great attractions for tourists and for those who enjoy Chinese food. JMost of todays Chinese Americans are the descendants of some of the early
24、miners and railroad workers. Those immigrants had come from the vicinity of Canton in Southeast China, where they had been uneducated farm laborers. The same kind of young men, from the same area and from similar humble origins, migrated to Hawaii in those days. There they fared far better, mainly b
25、ecause they did not encounter hostility. Some married native Hawaiians, and other brought their wives and children over. They were not restricted to Chinatown and many of them soon became successful merchants and active participants in general community affairs. KChinese Americans retain many aspect
26、s of their ancient culture, even after having lived here for several generations. For Example, their family ties continue to be remarkably strong(encompassing grandparents, uncles, aunts, cousins, and others). Members of the family lend each other moral support and also practical help when necessary
27、. From a very young age children are imbued with the old values and attitudes, including respect for their elders and a feeling of responsibility to the family. This helps to explain why there is so little juvenile delinquency(少年犯罪 )among them. LThe high regard for education which is deeply imbedded
28、 in Chinese culture, and the willingness to work very hard to gain advancement, are other noteworthy characteristics of theirs. This explains why so many descendants of uneducated laborers have succeeded in becoming doctors, lawyers, and other professionals.(Many of the most outstanding Chinese Amer
29、ican scholars, scientists, and artists are more recent arrivals, who come from Chinas former upper class and who represent its high cultural traditions.) MChinese Americans make up only a tiny fraction of our population; there are fewer than half a million, living chiefly in California, New York, an
30、d Hawaii. As American attitudes toward minorities and toward ethnic differences have changed in recent years, the long-reviled Chinese have gained wide acceptance. Today, they are generally admired for their many remarkable characteristics, and are often held up as an example worth following. And th
31、eir numerous contributions to their adopted land are much appreciated. 11 The old values and attitudes imparted into the young Chinese Americans effectively help prevent juvenile delinquency. 12 The construction of the transcontinental railroad was so tough and dangerous that a lot more Chinese labo
32、rers were imported to California to work as railroad builders. 13 At first, the Chinese lived in separate neighborhoods and made their own rules to solve disagreement. 14 The first Chinese arrived at the US in the hope of searching for gold. 15 Chinese immigrants to Hawaii were treated without hosti
33、lity, some of whom even became successful businessmen and actively participated in community affairs. 16 Most Chinese Americans worked in restaurants and laundries because of local peoples discrimination against them. 17 The descendants of illiterate laborers have become successful in many professio
34、ns partly because of the influence of Chinese culture which places great emphasis on education. 18 Few Chinese learned English at that time because they wouldnt stay in America for long. 19 The contributions made by Chinese to America had gained much appreciation. 20 The laws which barred the immigr
35、ation of Chinese laborers came to an end when America allied with China. Section C 20 A study published in the New England Journal of Medicine estimated that there are an average of 30 in-flight medical emergencies on U.S. flights every day. Most of them are not grave; fainting, dizziness and hyperv
36、entilation(换气过度 )are the most frequent complaints. But 13% of them roughly four a day are serious enough to require a pilot to change course. The most common of the serious emergencies include heart trouble(46%), strokes and other neurological problems(18%), and difficult breathing(6%). Lets face it
37、: plane riders are stressful. For starters, cabin pressures at high altitudes are set at roughly what they would be if you lived at 5,000 to 8,000 feet above sea level. Most people can tolerate these pressures pretty easily, but passengers with heart disease may experience chest pains as a result of
38、 the reduced amount of oxygen flowing through their blood. Low pressure can also cause the air in body cavities to expand as much as 30%. Again, most people wont notice anything beyond mild stomach cramping. But if youve recently had an operation, your wound could open. And if a medical device has b
39、een implanted in your body a splint, a tracheotomy(气管切开术 )tube or a catheter(导管 ) it could expand and cause injury. Another common in-flight problem is deep venous thrombosis(深静脉血栓 ) the so-called economy-class syndrome. When you sit too long in a cramped position, the blood in our legs tends to clo
40、t. Most people just get sore calves. But blood clots, left untreated, could travel to the lungs, causing breathing difficulties and even death. Such clots are readily prevented by keeping blood flowing; walk and stretch your legs when possible. Whatever you do, dont panic. Things are looking up on t
41、he in-flight-emergency front. Doctors who come to passengers aid used to worry about getting sued; their fears have lifted somewhat since the 1998 Aviation Medical Assistance Act gave them “good Samaritan“ protection. And thanks to more recent legislation, flights with at least one attendant are sta
42、rting to install emergency medical kits with automated defibrillators(电击去颤器 )to treat heart attacks. Are you still wondering if you are healthy enough to fly? If you can walk 150 ft. or climb a flight of stairs without getting winded, youll probably do just fine. Having a doctor close by doesnt hurt
43、, either. 21 Heart disease takes up about _ of the in-flight medical emergencies on US flights. （ A） 13% （ B） 46% （ C） 18% （ D） 6% 22 According to the passage, the expansion of air in body cavities can result in _. （ A） heart attack （ B） chest pain （ C） stomach cramping （ D） difficult breathing 23 A
44、ccording to the passage, why does deep venous thrombosis usually happen? （ A） Because the economy class is not spacious enough. （ B） Because there are too many economy-class passengers. （ C） Because passengers are not allowed to walk during the flight. （ D） Because the low pressure in the cabin prev
45、ents blood flowing smoothly. 24 According to the 1998 Aviation Medical Assistance Act, Doctors who came to passengers aid _. （ A） do not have to be worried even if they give the patients improper treatment （ B） will not be submitted to legal responsibility even if the patients didnt recover （ C） are
46、 assisted by advanced emergency medical kits （ D） will be greatly respected by the patient and the crew 25 The phrase “getting winded“(Line 2, Para. 5)is closest in meaning to _. （ A） falling over （ B） being out of breath （ C） spraining the ankle （ D） moving in a curving line 25 Teenagers are spendi
47、ng more money than ever. Just last year, 31.6 million teens spent 155 billion, according to the Northbrook, Illinois-based market research group Teenage Research Unlimited. Much of that money, of course, comes from parents. Shocked at how much money kids spend? Maybe you havent checked the price tag
48、s lately on some of the younger generations must-haves. To some, such extravagant spending on the notoriously fickle young might seem outrageous. Why do some parents give in? One factor is surely the sheer power of marketing through mass media. According to the group Adbusters, teenagers are exposed
49、 to an estimated 3,000 advertisements each day. Combine the ads with programming itself, like the fashion-, music- and skin-filled shows on MTV, and youve got a barrage of messages telling kids what they should own if they want to fit in. “The pressures on parents today are enormous,“ says Tom Vogele, a single father of twin 18-year-old girls in Newport Beach, Calif. “I truly believe it is harder today to raise children without spoiling them, not because parents
