Answer the questions below each text by choosing A, B, C or D. (40 points) 21 A tiny but powerful new lightweight drill has been developed by space
11、 scientists and engineers. It expands the fields in which drilling has been difficult in the past. The new drill could be used in the drilling required during surgical or diagnostic procedures involving bones, or when extracting heart pacemaker leads. Future space missions could include drilling for
12、 rock and soil samples, using only lightweight landing vehicles with robotic arms. The color photo shows the new driller penetrating a sandstone while the drill is held only from its power cord. Relatively small vertical force is used in this application a factor that will be useful when the drill i
13、s used in future space missions and weight needs to be kept to a minimum. The drill is driven by piezoelectric devices, which have only two moving parts but no gears or motors. Piezoelectrics are materials that change their shape under the application of an electrical field. The drill can be adapted
14、 easily to operations in a range of temperatures from extremely cold to very hot. Unlike conventional rotary drills, the drill can drill even the hardest rocks without significant weight on the drilling bit. “The drill is a device that offers exciting new capabilities for space exploration in future
15、 NASA missions,“ said Dr. Yoseph Bar-Cohen, who leads NASAs Jet Propulsion laboratorys Nondestructive Evaluation and Advanced Actuator Technologies unit. “Besides the immediate benefits of the technology to NASA, it is paving the way for other unique mechanisms that are being developed in our labora
16、tory and elsewhere,“ he said. The demonstration unit pictured in the color photograph weighs about 0.7 kilograms, which is sufficient to drill 12 millimeter diameter holes in rocks using less than 10 watts of power. Comparable rotary drills usually require the application of 20 to 30 times greater p
17、ushing force and more than three times the power. Other advantages to the drill are no drill noise and no drill movement across the surface on start-up. The drill body will not rotate, the speed does not decrease with time and the bit does not require sharpening. The bit can be guided by hand safely
18、 during operation. The drill can drill holes in different cross-sections, such as square and round. Said Dr. Yoseph Bar-Cohen, “Thanks to the development of technology associated with this drill, new devices can be made to be small and lightweight, to consume little power and to exhibit a high stand
19、ard of reliability.“ 21 At first, the new lightweight drill has been invented to （ A） be used in space missions. （ B） pull out the heart pacemaker leads. （ C） replace the conventional rotary drill. （ D） drill the bones during procedures of medical treatment. 22 A useful feature of the new drill for
20、space mission is （ A） its applicability. （ B） its lightweight. （ C） its multifunction. （ D） its flexibility. 23 According to the passage, the new drill （ A） cant drill holes in different cross-sections. （ B） needs significant weight on the bit when drilling the hardest rocks. （ C） needs more watts o
21、f power though it is cheaper than rotary drill. （ D） can work well in a range of temperatures from extremely cold to very hot. 24 We can infer from the passage that the patent of the drill is held by （ A） NASA. （ B） Dr. Yoseph Bar-Cohen. （ C） NASAs Jet Propulsion Laboratory. （ D） Cybersonics Incorpo
22、rated in Erie, Philadelphia. 25 Dr. Yoseph Bar-Cohen seems to suggest that （ A） the new drill is a perfect device without any defect. （ B） it is good for the new drill to be energy-saving. （ C） the technological advancement allows us to invent new devices with marked features. （ D） with the further
23、development of technology, the new drill can be made smaller and lighter. 26 In cities all over the United States, workers spend several hours a day in cars crawling along in traffic to get to offices many miles from home. They experience stress, waste time, and pay a lot for gas, car maintenance, a
24、nd parking. Once they get to work, they make their way through a maze of cubicles, each with its computer, phone, and file cabinet. Nancy Alley, human resources manager at TBWA Chiat Day, doesnt. She stays at home, talking with managers over the phone and faxing in paperwork. Instead of walking down
25、 the hall to chat with coworkers, she E-mails them. Nancy is a telecommuter, someone who works some or all of the time at home. Since 1990, the number of U.S. telecommuters has grown from 4.2 million to 9.2 million. Highway congestion, the high cost of office space, federal clean-air laws, reduced w
26、ork forces, and lifestyle needs all these factors contribute to the growth of telecommuting. What makes it possible is technology. Desktop and laptop personal computers, networking, videoconferencing, fax machines, E-mail, and multiple phone lines provide the fast and efficient communication require
27、d for telecommuting. The experiences of many companies suggest that telecommuting can increase workplace flexibility and enhance productivity. At Georgia Power Company, for example, a pilot telecommuting project was so successful that the company decided to triple its number of telecommuters. The co
28、mpany reduced the cost of leased office space by $100,000 a year, increased productivity among the telecommuting employees of its customer service center, and saved the workers a combined 750 commuter miles a day. Telecommuting, however, is not without its obstacles. At one computer software firm, t
29、he information systems manager offered telecommuting as an option to her 100-person staff. After three months, the staff members reported that being away from the office was counterproductive to their work. Programmers missed being able to drop by analysts cubicles with questions, and everyone re-po
30、rted they were interrupted at home more often. As part of its cost-cutting initiative, Nestle required 140 sales employees to telecommute. Facing many technical problems with telephone lines and frustratingly slow computer networking, most of these telecommuters found it an annoying experience. Tele
31、commuting also makes many employees feel isolated and out of touch, leading to decreased motivation and less, not more productivity. By blurring the barriers between work and family, telecommuting often leads to more work hours and more interference with family life. Telecommuting is not universally
32、 applicable. Jobs and individuals must be suitable, and staff must be capable of managing telecommuters. In addition, technological improvements, such as high-speed modems, are crucial. Few people expect to conduct business regularly from a tropical island or mountain resort any time soon. 26 In the
33、 passage, the author introduces his topic by （ A） explaining a phenomenon. （ B） raising an argument. （ C） posing a contrast. （ D） using an example. 27 More people choose to telecommute because （ A） they dont like their working environment. （ B） the development of technology enables them to work at h
34、ome. （ C） telecommuting can solve many social problems. （ D） telecommuting is a trend that most people like to follow. 28 The word “counterproductive“(Paragraph 4) probably means （ A） producing challenges. （ B） producing counters. （ C） producing results. （ D） producing problems. 29 Telecommuting may
35、 affect a telecommuters family life because （ A） telecommuters are required to do more work. （ B） the routine of their family life is disturbed. （ C） telecommuters family dont like them working at home. （ D） there is no distinction between work and family life. 30 What can we infer from the last par
36、agraph? （ A） The application of telecommuting is influenced by many factors. （ B） Only those who are highly-motivated can be telecommuters. （ C） Although telecommuting brings benefits, it also causes problems. （ D） People dont like doing business in a remote area. 31 The costs associated with natura
37、l disasters are increasing rapidly. As a result, officials in government and industry have focused more attention on disasters and their effects. The White House Office of Science and Technology Policy has estimated that disasters cost the country, about 1 billion per week. Hurricane Andrew, the Mid
38、west flood of 1993, and the Hanshin earthquake have shown that individual disasters can cost tens if not hundreds of billions of dollars. This increasing cost has resulted in greater funding from government and industry for the development of technologies related to disaster prediction, and has led
39、to more research into the effective use of predictive information. The insurance industry has long been aware of the dangers of natural disasters; the 1906 earth-quake in San Francisco, California, bankrupted scores of insurance companies. But the industry has focused particular attention on disaste
40、r prediction in recent years, as spiraling costs revealed that many companies had underestimated their financial exposure. For instance, prior to Hurricane An-drew in 1992, many insurance experts thought that the worst hurricane possible would do no more than 8 billion in damages Io the industry. Th
41、e damages caused by Hurricane Andrew, estimated at about 17 billion, shattered these beliefs. Today, estimates of worst-case disaster scenarios approach 100 billion. The insurance industry has therefore increased its support for research into disaster prediction. One such effort involves a number of
42、 companies that have joined together to support the Bermuda-based Risk Prediction Initiative, which funds disaster research. The expectation is that the resulting information will place the industry on a more solid foundation to make decisions about the risk of future disasters. The industry has als
43、o lobbied for the government to bear some of the financial burden of disaster insurance. Such a program already exists for flood insurance, set up in the late 1960s by the federal government to insure flood-prone areas. These types of programs, effectively implemented, could be increasingly necessar
44、y in the future to make insurance available in areas prone to disasters. Because the stakes are so high, the science of disaster prediction has a bright future. The various projects and programs illustrate that disaster prediction is a topic of concern to scientists and policy-makers alike. Hurrican
45、es, tornadoes, floods, earthquakes, tsunamis, and volcanoes all show that the effective use of disaster predictions not only requires advanced technology but also requires that society consider the entire process of prediction forecasts, communication, and use of information. Because they cannot pre
46、dict the future with certainty, and because much remains to be learned, scientists warn that society must understand the limits of scientific predictions and be prepared to employ alternatives. Wisely used, however, disaster prediction has the potential to reduce societys vulnerability to natural di
47、sasters. 31 The result of the increasing costs in natural disasters is （ A） great loss suffered by commercial companies. （ B） organizations increased attention on disasters. （ C） individual awareness to natural disasters. （ D） more funds to support the prediction research. 32 The difference between
48、the actual loss caused by Hurricane Andrew and the loss estimated by insurance companies before the hurricane is （ A） 1 billion dollars. （ B） 8 billion dollars. （ C） 9 billion dollars. （ D） 17 billion dollars. 33 The purpose of insurance companies to support disaster prediction research is that （ A）
49、 companies want to make more money from the insured places. （ B） companies may thus have a better idea of the future risks. （ C） companies can get more sympathies from the government. （ D） companies intend to make use of peoples trust in the industry. 34 The key factor to reduce societys vulnerability to natural disasters is （ A） insurance companies should be wise enough in their estimates of losses. （ B） the government should bear some of the financial risks of disaster insurance. （ C） t
