单选题{{B}}Directions: For each blank in the following passage, there are four choices marked A, B, C and D. Choose the one that is most suitable and write down the corresponding letter.{{/B}} Most young people enjoy physical activities, walking, cycling, football, or mountaineering. These who have a passion{{U}} (21) {{/U}}climbing high and difficult mountains are often looked upon with astonishment. Why are men and women{{U}} (22) {{/U}}to suffer cold and hardship, and to{{U}} (23) {{/U}}on high mountains? This astonishment is caused, probably, by the difference between mountaineering and other forms of activities{{U}} (24) {{/U}}which men give their leisure. There are no man-made rules, as there are for{{U}} (25) {{/U}}as golf and football. There are, of course, rules of different kinds which it would be dangerous to ignore, but it is this freedom from man-made rules{{U}} (26) {{/U}}makes mountaineering attractive to many people. Those who climb mountains are free to their own methods. If we{{U}} (27) {{/U}}mountaineering with other more familiar sports, we might think that one big difference is that mountaineering is not a "team work". However, it is only our misunderstanding. There are, in fact, no "matches"{{U}} (28) {{/U}}"teams" of climbers, but when climbers are on a rock face linked by a rope on which their lives may{{U}} (29) {{/U}}, obviously, there is teamwork. A mountain climber knows that he may have to fight with natural{{U}} (30) {{/U}}that are stronger and more powerful than man. His sport requires high mental and{{U}} (31) {{/U}}qualities. A mountain climber{{U}} (32) {{/U}}to improve on skill year after year. A skier is probably past his best by the age of thirty, and most international tennis champions{{U}} (33) {{/U}}in their early twenties. But it is not{{U}} (34) {{/U}}for men of fifty or sixty to climb the highest mountains in the Alps. They may take more{{U}} (35) {{/U}}than younger men, but they probably climb more skill and less waste of effort, and they certainly experience equal enjoyment.

单选题{{B}}Text 2{{/B}} President Bush has once again started speaking out for comprehensive immigration reform, and a draft plan to rally Republican senators on the issue is circulating just as Congressional hearings on the issue approach. Members of Congress recognize that voters are looking for real reform that rests on resolute, effective enforcement of our immigration laws. The only serious legislative proposal on the table offers such enforcement, because it focuses on making employers accountable for their hiring practices. To that end, the bill incorporates lessons learned from the largest immigration enforcement operation ever undertaken. Last December, Department of Homeland Security agents descended on meat processing plants run by Swirl & Company in six states, arresting more than 1,200 unauthorized workers. The arrests were astonishing because Swift participates in Basic Pilot, a voluntary Department of Homeland Security program that allows employers to electronically verify the work eligibility of newly hired workers against department and Social Security databases. The program is seen as the precursor for a verification system that would become mandatory with comprehensive immigration reform. Since Swirl was using the department's system, how did it end up with illegal workers? The Basic Pilot program has a fatal flaw, which is that it requires only electronic verification of employment qualification. An effective program should also insist on tamper-proof identification documents for job-seekers, incorporating biometrics like digital photographs and fingerprints to prove identity. Only then would it be possible to establish not only that job applicants are authorized to work, but also that they are who they say they are. Otherwise, valid Social Security numbers can be presented to employers, and Basic Pilot will verify them, but the numbers may not belong to the workers who present them. To insist on secure documents with biometric identifiers is not a call for a national ID. Green cards, temporary work permits and passports are secure and reliable for hiring purposes. Adding Social Security cards to this list, establishing a single standard for their security features, and replacing old cards over a designated period would resolve the problem on a national scale. Only then would employers be able to comply reliably with verification requirements as the basis for sound enforcement and, by extension, border control. Legal immigrants and American citizens could prove their identities and qualifications to work without facing discrimination based on appearance or language. Scarce enforcement resources could be spent on apprehending real criminals and addressing national security threats. And a new system of enforcement would at last have a chance to win back public confidence in the nation's immigration policies. After more than 20 years of failed efforts, Congress must not bake half a loaf. Secure biometric Social Security cards are an essential ingredient in any comprehensive immigration reform.

单选题At the end of the nineteenth century, a rising interest in Native American customs and an increasing desire to understand Native American culture prompted ethnologists to begin recording the life stories of Native American. Ethnologists had a distinct reason for wanting to hear the stories: they were after linguistic or anthropological data that would supplement their own field observations, and they believed that the personal stories, even of a single individual, could increase their understanding of the cultures that they had been observing from without. In addition many ethnologists at the turn of the century believed that Native American manners and customs were rapidly disappearing, and that it was important to preserve for posterity as much information as could be adequately recorded before the cultures disappeared forever. There were, however, arguments against this method as a way of acquiring accurate and complete information. Franz Boas, for example, described autobiographies as being "of limited value, and useful chiefly for the study of the perversion of truth by memory," while Paul Radin contended that investigators rarely spent enough time with the tribes they were observing, and inevitably derived results too tinged by the investigator"s own emotional tone to be reliable. Even more importantly, as these life stories moved from the traditional oral mode to recorded written form, much was inevitably lost. Editors often decided what elements were significant to the field research on a given tribe. Native Americans recognized that the essence of their lives could not be communicated in English and that events that they thought significant were often deemed unimportant by their interviewers. Indeed, the very act of telling their stories could force Native American narrators to distort their cultures, as taboos had to be broken to speak the names of dead relatives crucial to their family stories. Despite all of this, autobiography remains a useful tool for ethnological research: such personal reminiscences and impressions, incomplete as they may be, are likely to throw more light on the working of the mind and emotions than any amount of speculation from an ethnologist or ethnological theorist from another culture.

单选题People talked about a promising idea: using the electrical wiring already in the house to move data from room to room. One early application, the X10 system for controlling lights and appliances, didn"t always work welL The technology was certainly not ready to be used to bring web pages to computers anywhere in the house. Along came the wireless network. For $ 50, you could get the Ethernet sprayed across the house and never be confined by a cord to the wall. It was slow in those early days, very unreliable, and open to interruption if you couldn"t bother with setting up the encoded passwords. But it caught on. According to estimates made by Parks Associates, a market research firm based in Dallas, about 12.5 million homes now have wireless networks; another 10 million homes, mostly newer ones, have Ethernet. Cheap and prevalent is a hard combination to beat. However, technology companies continued to work on the idea. A version for power lines called Home Plug came out in 2002, and while it hardly affected sales of wireless network equipment, it sold enough that major companies like Intel, Cisco Sony, Sharp and Comcast created the Home Plug Alliance to push for next-generation products, with the first to come out later this year. Some companies are not waiting. Panasonic, Netgear, Maranta are already offering products that will move data through home electrical lines faster than routers using the current Wi-Fi standard for wireless networking. Panasonic started selling its HD-PLC Ethernet adapters for power lines last month. One adapter is attached to a router with a short Ethernet cable and plugged into a nearby wall socket. The second device is plugged into a socket elsewhere in the house. When a computer is linked to it with an Ethernet cable, data is transmitted through the home"s electrical wiring at speeds of up to 190 megabits a second. Netgear will be selling a similar system next month for about $ 300. It moves data at a slightly faster rate. Marantz says its ZR6001SP receiver will send music to special speakers in another room over power lines. The system includes both devices. The music listener controls the receiver and the CD players connected to it form a control pad on the speakers. These products seem hopeless candidates. Who would like to pay two or three times expensive than wireless network? The answer lies in simplicity. "It"s why most people need us," Robert said, noting the complexity of installing wireless network is evident by the fact that return rates on wireless networking devices drop to nearly zero. The three products" makers said that people who cannot get whole-house coverage with a wireless system or those plagued by dead zones might find it appealing.
