英语 全国职称英语等级考试试题(理工类) 附答案
第一部分阅读理解(75分)Passage 1CATV is a short way of saying "community antenna (天线) television." But "cable television" is the term most people use. Cable television allows viewers to receive TV programs that they cannot pick up with their regular antennas.Television signals do not follow the curve (曲线) of the earth. They travel in straight lines in all directions. Signals from a TVstation move toward the horizon (水平线) and then go into space. If you live only a few miles from a station, you may not get any picture at all.CATV began in 1948. People in places far from TV stations sharedthe cost of putting up high antennas. A community antenna wasusually placed on a hill, a mountain, or on a high tower. The antenna picked up TV signals and fed them into a small local station. From the station, thick wires called cables ran out to nearby homes. Each person using the cable paid a monthly charge. CATV worked well, and soon new uses were found for it. Localstations could feed programs into empty channels that were not in use. People along the cable could have local news, weather reports, and farm and school news at no extra charge.Today, cable television has moved into cities. It brings in extra programs that city viewers with regular antennas cannot see. It is also used in many classrooms throughout the country.1. From the first paragraph we know that ________.○A.most people use cable television○B."community antenna" is another name for "regular antenna"○C. a community antenna is used for cable television○D.regular antennas cannot pick up TV signals programs2. Of the following, which is NOT the way TV signals travel?○A.In a curve.○B.In a straight line.○C.In all direction.○D.Toward the horizon.3. Cable TV is becoming more and popular because _____________.○A.it is free of charge○B.it can provide more programs○C.it provides all TV users good pictures○ sets with regular antennas can also have a good reception through CATV4. On the whole, this passage is about ________.○A.how to put up high antennas○B. a way of picking up better TV programs○C.how to use the empty channels on your TV set○D.the way that TV signals are sent5. From the passage we can infer that __________.○ has begun to be used for educational purposes○B.there is no charge for CATV○C.cable TV cannot be used in mountainous areas○D.antennas for cable TV are usually put up in the center of a communityPassage 2In earliest times, men considered lightning to be one of the great mysteries of nature. Some ancient people believed that lightning and thunder were the weapons of the gods.In reality, lightning is a flow of electricity formed high above the earth. A single flash of lightning 1.6 kilometers long has enough electricity to light one million light bulbs.The American scientist and statesman, Benjamin Franklin, was the firstto show the connection between electricity and lightning in 1752. In the same year he also built the first lightning rod. This device protects buildings from damage by lightning.Modern science has discovered that one stroke of lighting contains more than 15 million volts. A spark between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second.Scientists estimate that there are about 2000 million flashes of lightning per year. Lightning hits the Empire State Building in New York City 30 to 48 times a year. In the United States along itkills an average of one person every day.The safest place to be in case of an electrical storm is in a closed car. Outside, one should go to low ground and not get under trees. Also, one should stay out of water and away from metal fences. Inside a house, people should avoid open doorways and windows and not touch wires or metal things.With lightning, it is better to be safe than sorry!6. Lightning is really __________.○A.weapon○B.electricity○C.light○D.mystery7. People once though that lightning came from __________.○A.scientists○B.ground○C.lightning rod○D.gods8. One flash of lightning can produce enough electricity for ______ bulbs.○A.10,000○B.1,000○C.1,000,000○D.1009. Benjamin Franklin ___________.○A.made the first lightning rod○B.invented electricity○C.built the Empire State Building○D.prevented Lightning from hitting cars10. _________ is the best place to be during an electrical storm.○A.Swimming pool○B. a high ground○C.Under a tree○D. A carPassage 3Because of the energy crisis, scientists in the oil-consuming nations have become increasingly interested in the potential(潜在的) of solar energy. Some experts estimate that the present supply of fossil (化石) fuel will not last until the end of the twentieth century. The problem that solar energy researchers face is how to harness (利用) the sun's energy effectively and inexpensively. One of the mostpopular methods currently being tested uses rooftop solar collectorsand underground storage tanks. An advantage of a properly working system of this type is that it will not create any environmental pollution. Another advantage of using solar energy is that the costof the fuel-the sun's rays-is zero. When a solar heating system is working at maximum (最大的) efficiency, it can provide up to 80 percent of winter heating needs.11. The main topic of this passage is __________.○A.the shortage of fossil fuel○B.the problems that energy researchers face○C.an environmental pollution problem○D.an inexpensive energy source12. One popular solar heating system makes use of __________.○A.roof collectors and underground storage○B.fossil fuel conversion○C.underground oil tanks○D.water collection and evaporation13. The cost of using the sun's rays for heating is ___________. ○A.about the same as the cost of fossil fuels○B.several hundred dollars per year○C.negligible compared with other energy sources○D.determined by the severity of the winter14. Which of the following describes an advantage of using solar energy?○A.There is little or no environmental pollution.○B. A large percentage of fuel costs can be saved.○C.Fossil fuels will become more plentiful.○D.The oil-consuming nations will not have to import oil.15. According to some experts, the supply of fossil fuel will not last _______.○A.one more century○B.an indeterminable time○C.until the end of this century○D.indefinitely第二部分完成句子(25分)根据短文内容完成句子，每个空格只能填一个单词。
