职称英语考试《理工类》章节练习题精选及答案0517-1011、Cell Phone Lets Your Secret OutYour cell phone holds secrets about you. Besides the names and numbers that you've programmed into it, traces of your DNA linger on the device, according to a new study.DNA is genetic material that ______ in every cell. Like your fingerprint, your DNA is unique to you-because you have an identical twin. Scientists today routinely analyze DNA in blood, saliva, or hair left behind at the scene of a crime. The results often help detectives identify criminals and their victims. Your cell phone can reveal more about you than you might think. Meghan J. McFadden, a scientist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone and later dropped the device. This made her wonder whether traces of DNA lingered on cell phones even when no blood was involved. So she and colleague Margaret Wallace of the City University of New York analyzed the flip open phones of 10 volunteers. They used swabs tocollect invisible traces of the users from two parts of the phone: the outside, where the user holds it, and the speaker, which is placed at the user's ear.The scientists scrubbed the phones using a solution made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back for another week. Then the researchers collected the phones and repeated the swabbing of each phone once more.The scientists discovered DNA that belonged to the phone's speaker on each of the phones. Better samples were collected from the outside of each phone, those swabs also picked up DNA that belonged to other people who had apparently also handled the phone. Surprisingly, DNA showed up even in swabs that were taken immediately after the phones were scrubbed. That suggests that washing won't remove all traces of evidence from a criminal's device. So cell phones can now be added to the list of clues that can clinch a crime scene investigation.【单选题】A.appealB.appointC.appearsD.applies正确答案:C答案解析:这个句子的意思是：DNA是一种存在于每一细胞中的基因物质。

职称英语考试《理工类》章节练习题精选及答案0517-1281、Animal＇s "Sixth Sense"A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa, Wild animals, however, seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a "sixth sense" for disasters, experts said.Sri Lankan Wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island＇s coast clearly missed wild beasts, with no dead animals found."No elephants are dead, not ______ a dead rabbit. I think animals can sense disaster. They have a sixth sense. They know when things are happening" H. D. Ratnayake, deputy director of Sri Lanka＇s Wildlife Department, said about one month after the tsunami attack. The waves washed floodwaters up to 2 miles inland at Yala National Park in the ravaged southeast, Sri Lanka＇s biggest wildlife reserve and home to hundreds of wild elephants and several leopards."There has been a lot of scientific evidence about dogs barking or birds migrating before volcanic eruptions or earthquakes. But it has not been proven," said Matthew van Lierop, an animal behavior assistant at Johannesburg Zoo. "There have been no specialist studies because you can＇t really test it in a lab or field setting," he told Reuters. Other authorities concurred with this assessmetn."Wildlife seem to be able to pick up certain phenmenon, especially birds. There are many reports of birds detecting impending disasters," said Clive Walker, who has written several books on African wildlife.Animals certainly rely on the known senses such as smell or hearing to avoid danger such as predators. The notion of an animal "sixth sense" -or some other mythical power-is an enduring one which the evidence on Sri Lanka＇s ravaged coast is likely to add to. The Romans saw owls as omens of impending disaster and many ancient cultures viewed elephants as sacred animals endowed with special powers or attributes.【单选题】A.suchB.tooC.soD.even正确答案:D答案解析:从上下文判断，本句的意思应该是：没有大象死亡，甚至连一只兔子也没有死亡。

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。

Around the world, people are starting to measure the effects of global warming - and trying to figure out what to do about it.Scientists recently used satellites to study the temperatures of lakes around the world, and they found that lakes are heating up.Between 1985 and , satellites recordedthe nighttime temperatures of the surfaces of 167 lakes. During those 24 years, the lakes got warmer - by an average of about 0.045 degree Celsius per year.In some places, lakes have been warming by as much as 0.10 degree Celsius per year. At that rate, a lake may warm by a full degree Celsius, or 1.8 degrees Fahrenheit, in just 10 years. That difference may seem small - you might not even notice it in your bathtub. But in a lake, slightly warmer temperatures could mean more algae, and algae can make the lake poisonous to fish.The study shows that in some regions, lakes are warming faster than the air around them. This is important because scientists often use measurements of air temperature to study how the Earth is warming. By using lake temperatures as well, scientists can get a better picture of global warming.The scientists say data on lakes give scientists a new way to measure the impact of climate change around the world.That's going to be useful, since no country is too big or too small to ignore climate change. Scientists aren't the only ones concerned. Everyone who lives on Earth is going to be affected by therapidwarming of the planet.Many world leaders believe we might be able to do something about it, especially by reducing the amount of greenhouse gases we put into the air.That's why the United Nations started the Framework Convention on Climate Change, or UNFCCC. Every year the convention meets, and representatives from countries around the world gather to talk about climate change and discuss global solutions to the challenges of a warming world.16 Scientist have been keeping records of lake temperatures for over 30 years.A RightB WrongC Not mentioned17 The temperatures of lakes around the world have increased greatly between 1985 and .A RightB WrongC Not mentioned18 Lakes seem to be warming faster in Asia.A RightB WrongC Not mentioned19 A slight temperature increase in a lake could be harmful to fish.A RightB WrongC Not mentioned20 Scientists generally focus on air temperatures when studying global warming.A RightB WrongC Not mentioned21 Globle warming is less threatening to small countries.A RightB WrongC Not mentioned22 UNFCCC's annual meeting will be held in Mexico this year.A RightB WrongC Not mentioned第3部分：概括大意与完成句子（第23～30题，每题1分，共8分）下面的短文后有2项测试任务：（1）第23～26题要求从所给的6个选项中为第2～5段每段选择1个最佳标题；（2）第27～30题要求从所给的6个选项中为每个句子确定一个最佳选项。

职称英语考试《理工类》章节练习题精选及答案0517-251、Dairy Price-fixing ScandalTesco is preparing a legal battle to clear its name of involvement in the dairy price-fixing scandal that has cost consumers ￡270 million. Failure to prove that it had no part in collusion with other supermarkets and dairy processors may land it with a fine of at least ￡80 million. The Office of Fair Trading (OFT) said yesterday that Asda, Sainsbury's and the former Safeway, plus the dairy companies Wiseman, Dairy Crest and Cheese Company, had admitted being in a cartel to fix prices for milk, butter and cheese. They were fined a total of just over ￡116 million as part of a leniency deal offered by the watchdog to companies that owned up quickly to anti-competitive behaviour.Officials at the OFT admitted privately that they did not think they would ever discover which company or individual had initiated the pricing formula. But the watchdog recognises that at the time supermarkets were under pressure from politiciansand farmers to raise the cost of milk to save dairy farming, though it is not certain that money found its way to farmers. The OFT claimed in September that it had found evidence that the retail chains had passed future milk prices to dairy companies, which then reached a fixed price among themselves.The average cost to each household is thought to be ￡11.25 over 2002 and 2003, Prices went up an extra 3p on a pint of milk, 15p on a quarter of a pound of butter and 15p on a half pound of cheese. There is no direct recompense for consumers, however, and the money will go to the Treasury. The National Consumer Council gave warning that the admissions would dent consumer confidence in leading high street names and that people would become sceptical of their claims. Farmers for Action, the group of farmers that has led protests over low milk prices since 2000, is seeking legal advice on whether it can now bring a claim for compensation.The OFT investigation is continuing, however, in relation to Tesco, Morrisons and the dairy group Lactalis McLelland, and any legal action is expected to be delayed until that is completed. Tesco was defiant and said that it was preparing a robust defence of its actions. Lucy Neville-Rolfe, its executive director, said: "As we have always said, we acted independentlyand we did not collude with anyone. Our position is different from our competitors and we are defending our own case vigorously. Our philosophy is to give a good deal to customers." Morrisons has supported the OFT in inquiries into the former safeway business that it took over, but in a statement said that it was still making "strong representations" in its defence. A spokeswoman for Lactalis McLelland said that the company was "co-operating" with the OFT. Industry insiders suggested that the three companies were deliberately stalling the OFT investigation.Sainsbury's admitted yesterday that it had agreed to pay ￡26 million in fines, but denied that it had sought to profiteer. Justin King, the chief executive, said he was disappointed that the company had been penalised for actions meant to help farmers but recognised the benefit of a speedy settlement. Asda declined to say how much it would pay in fines and also said that its intention had been to help farmers under severe financial pressure.The writer's attitude to Tesco can be said to be ______.【单选题】A.biased。

职称英语考试《理工类》章节练习题精选及答案0517-391、An Intelligent CarDriving needs sharp eyes, keen ears, quick brain, and coordination between hands and the brain. Many human drivers have all. these and can control a fast-moving car. But how does an intelligent car control itself ?There is a virtual driver in the smart car. This virtual driver has "eyes," "brains", "hands" and "feet", too. The mini-cameras on each side of the car are his "eyes," which observe the road and conditions ahead of it. They watch the traffic to the car's left and right. There is also a highly automatic driving system in the car. It is the built-in computer, which is the virtual driver's "brain". His "brain" calculates the speeds of other moving cars near it and analyzes their positions. Basing on this information, it chooses the right line for the intelligent cars, and gives ______ to the "hands" and "feets" to act accordingly. In this way, the virtual driver controls his car.What is the virtual driver's best advantage? He reacts rapidly.The mini-cameras are sending images continuously to the "brain". It completes the processing of the images within 100 milliseconds. However, the world's best driver at least needs one second to react. Besides, when he takes action, he needs one more second.The virtual driver is really wonderful. He can reduce the accident rate. considerably on expressway. In this case, can we let him have the wheel at any time and in any place? Experts warn that we cannot do that just yet. His ability to recognize things is still limited. He can now only drive an intelligent car on expressways.【单选题】A.spaceB.locationsC.instructionsD.time正确答案:C答案解析:根据空白所在的局部结构，以使它们做出相应的动作判断，C（指令）是答案。
