2007年职称英语考试理工类(C级)试题及答案

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1个最佳选项。
　　Unlocking the Human Genome(基因组)
　　1A project to unlock secrets-what scientist could resist that challenge?This is what many scientists are doing as they work on the Human Genome Project.The aim of the project is to decode(破译)all of the some 100,000 genes in the human body.Scientists are using DNA fingerprinting techniques to do the decoding.
　　2DNA is the substance found in the chromosomes(染色体)of a cell.A chromosome is a chain of genes.Each gene carries a piece of genetic information.At any one moment in a cell,thousands of genes are turned on and off to produce proteins(蛋白质).The challenge for scientists is to find out what role each gene plays in protein production.At some point this decoding will be complete.Then scientists will have a map of an ideal genome,or a picture of the total genetic nature of a human being.The ideal genome is called a consensus(交感)genome.Everything works well in a consensus genome.
　　3But no one in the world has a consensus genome.Everyone’s genome is different from the ideal.These differences are referred to as genetic mutations(突变).Genetic mutations in a person’s genome mean that the person has a greater than average chance of suffering from health problems.Some problems are not life-threatening.These would include things like colorblindness,or mild headaches.Other problems are serious,such as heart disease,or cancer.
　　4It will take years to identify the role of each of the 100,000 genes,The short-term goal of the project is to find the physical and mental health problems a person is likely to encounter during his or her lifetime.The long-term goal is to have each person live a longer,healthier life.

第4部分：阅读理解(第31~45题，每题3分，共45分)
　　下面有3篇短文，每篇短文后有5道题。请根据短文内容，为每题确定1个最佳选项。

　　第一篇Motoring Technology
　　1.2 million road deaths worldwide occur each year,plus a further 50 million injuries.To reduce car crash rate,much research now is focused on safety and new fuels-though some electric vehicle and biofuel research aims at going faster.
　　Travelling at speed has always been dangerous.One advanced area of research in motoring safety is the use of digital in-car assistants.They can ensure you don’t miss important road signs or fall asleep.Most crashes result from human and not mechanical faults.
　　Some safety developments aim to improve your vision.Radar can spot obstacles in fog,while other technology“sees through”big vehicles blocking your view.
　　And improvements to seat belts,pedal(脚踏)controls and tyres are making driving smoother and safer.The colour of a car has been found to be linked with safety,as have,less surprisingly,size and shape.
　　But whatever is in the fuel tank,you don’t want a thief in the driving seat and there have been many innovations(创新).Satellite tracking and remote communications can also come into play if you crash,automatically calling for help.
　　Accidents cause many traffic jams,but there are more subtle interplays between vehicles that can cause jams even on a clear but busy road.Such jams can be analyzed using statistical tools.Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyons’s personal chauffeur(司机),but their latest efforts suggest that won’t be soon.
　　31.To reduce car crash rate,many scientists are working hard to
　　A.design fully automatic cars.
　　B.develop faster electric vehicles.
　　C.analyze road deaths occurring worldwide each year.
　　D.improve the safety of cars and develop new fuels.
　　32.According to the second paragraph,most road accidents happen due to
　　A.heavy traffic.
　　B.human mistakes.
　　C.engine failure.
　　D.bad weather.
　　33.Which of the following safety developments is NOT mentioned in the passage?
　　A.Windscreens that can help drivers to improve their vision.
　　B.Radars that can help drivers to see obstacles in fog.
　　C.Devices that can help drivers to see through big vehicles.
　　D.Improvements in seat belts,pedal controls and tyres.
　　34.Satellite tracking and remote communication systems cna be used to
　　A.reduce oil consumption.
　　B.remove the obstacles on the road.
　　C.call for help when one’s car crashes.
　　D.help drivers get out of a traffic jam.
　　35.Which of the following statements is true of robotic drivers?
　　A.It will take some time before robotic drivers are available.
　　B.Robotic drivers are not allowed to driveon busy roads.
　　C.Robotic drivers can never replace human drivers.
　　D.Robotic drivers are too expensive to use.
