Intrared(红外线的)radiation is an electromagnetic waveWhen it is absorbed by matter，heat is produced.Waves of infrared and visible light have more energy than waves of radio，television，or radarUltraviolet rays(紫外线)and，X-rays are electromagnetic waves with even greater amounts of energy . Infrared radiation is used in cooking food and heating buildings . Sunlight and electric lights are part of our requirements for normal livingUltraviolet radiation is useful in killing certain disease organismsX-rays and gamma rays have so much energy that they travel right through solid objectsThey can be used to detect and treat cancerX-rays are used in industry to find hidden cracks in metal，and in medicine to reveal broken bones4 Usually we use electricity to generate electromagnetic energyThe source of most of our energy is the sunHeat from the sun causes water to evaporateWhen the water falls to the earth as rain，some of it is trapped behind dams and then used to operate electric generatorsOther generators are powered by coal，but the energy stored in coal came from the suntoo5 Until recently,the source of the tremendous amount of energy given off by the sun was a puzzleIf the sun depended on chemical reactions，it would have used up all its energy long agoExperiments with electromagnetic radiation led to the theory that mass can be converted into energyAbout forty years after the theory was proposed，nuclear energy was harnessed(利用)by manChemical energy comes from electron(电子) rearrangement. Nuclear energy comes from a change in the nucleus of an atomCompared with chemical reactionsnuclear reactions release millions of times more energy per pound of melWe now believe that the sun's energy comes from the nuclear reactions in which hydrogen is changed into helium (氦)6 Nuclear energy is beginning to compete with coal as an economical source of power to generate electricityIt is also being used to operate engines in large shipsScientists continue to seek new and better methods of obtaining and using energy.23 Paragraph 3_24 Paragraph 4_25 Paragraph 5_26 Paragraph 6_A Nuclear Reactions as the Lasting Source of the Sun's EnergyB The Most lmportant Source of EnergyC Types of Electromagnetic EnergyD The Machines Used for Energy GenerationE Seeking New Sources of EnergyF The Use of Ultraviolet Radiation in Medicine27 One can get a sunburn even _.28 Infrared radiation can produce heat _.29 X-rays and gamma rays can be used to detect andtreat cancer_ .30 Chemical energy is generated _.A when it is absorbed by matterB when it is cloudyC because they can pass through solid objectsD when the sunrays are fierceE when a change in the nucleus of an atom takes placeF when electron rearrangement takes place第4部分：阅读理解（第3145题，每题3分，共45分）下面有3篇短文，每篇短文后有5道题，每题后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题，从4个选项中选择1个最佳答案涂在答题卡相应的位置上。第一篇 A Thirsty WorldThe world is not only hungry,it is also thirsty for waterThis may seem strange to you，since nearly 75of the earth's surface is covered with waterBut about 97of this huge amount is sea-wateror saIt waterMan can only drink and use the other 3-the fresh water that comes from rivers，lakes，underground，and other sourcesAnd we cannot even use all of that, beeause some of it is in the fonn of icebergs(冰山)and glaciers (冰川)Even worse,some of it has been po1lutedAt the moment，this small amount of flesh water is still enough for us.Howeve，our need for water is increasing rapidlyOnly if we take steps to deal with this problem now can we_avoida severe worldwide water shortage later onA limited water supply would have a bad eriect on alriculture and industryIn addition to stopping wasting our precious water,one useful step we shouId take is to develop ways of reusing it . Experiments have already been done in this field，but only on a small scaleToday,in most large cities，water is used only once and it eventually retums to the sea or runs into underground storage tanksBut it is possible to pipe water that has been used to apurifying(净化)plantThere it can be filtered(过滤)and treated with chemicals so that it can be used again just as if it were flesh from a springBut even if every large city purified and reused its water，we still would not have enougn.Where could we tum next?To the oceans!All we'd have to do to make use of the vast amount of sea-water is-remove the saltThis salt-removing process is already in use in many Parts of the worldSo if we take a11 these steps，we'11 be in no danger of drying up !31 The phrase''the world"in the first line of the passage refers toA "man"B "you"C "woman"D "they"32 What percentage of the earth's water can man actually use at present?A Nearly 75 per centB About 97 per centC Exactly 3 per centD Lessthan 3 per cent33 According to the passage，we can avoid a worldwide water shortage in the future byA increasing rainfallB reusing water and utilizing sea-water.C cutting down our consumption of water.D reducing the number of factories producing steel34 Which of the following statements，according to the passage，is NOT true?A A limited water supply will affect industrial productionB Every large city purifies and reuses its waterC Purified water is not exactly as flesh as spring waterD Oceans are the largest water source35 According to the passage，sea-water can be turned into flesh water byA heating it upB treating it with chemicalsC taking salt out of itD drying it up.第二篇 Nonverbal Thinking in EngineeringMany objects in daily use have clearly been influenced by scienceHowever,their form and tunctlon，their dimensions and appearance，were determined by technologistsdesignersinventors，and engineers using nonscientific modes of thoughtMany features and qualities of the objects that a technologist thinks about cannot be reduced to clear verbal descriptions；they are dealt with in the mind by a visual，nonverbal processPyramids，cathedrals，and rockets exist notbecause of geometry or thermo-dynamics(热动力学)，but because they were first the picture in the minds of those who built themThe creative shaping process of a technologist's mind can be seen in nearly every artifact (人工制品) that existsFor example，in designing a diesel engine ，a technologist might express individual(个人的)ways of nonoerbal，thinking on the machine by continually using an intuitive (直觉的)sense of rightness and fitnessWhat would be the shape of the combustion chamber (燃烧室)?Where should the valves(阀)be placed?Such questions have a range of answers that are supplied by experience，by physical requirement，by limitations of available spaceand not in the least by a sense of formSome decisions，such as wall thickness and pin diameter,may depend on scientific calculations，but the nonscientific component design remains primaryDesign courses，then，should be an essential element of engineering curriculaNonverbal thinking，a central mechanism in engineering design，involves perceptions，which is the specialtechmque of the artist，not the scientistBecause perceptive processes are not assumed to need"hard thinking"，nonverbal thought is sometimes seen as a primitive stage in the development of cognitive processes and inferior to verbal mathematical thoughtIf courses in design，which in a strongly analytical(分析的)engineering curriculum provide the background required for practical problem-solving，are not provided，we can expect toencounter silly but costly errors occurring in advanced engineering systemsFor exampleearly modes of high-speed railroad cars loaded with high-tech controls were unable to operate in a snowstorm because the fan sucked snow into the electrical systemRandom failures that bring automatic control systems into trouble are a reflection of the chaos that results when design is assumed to be primarily a problem in mathematics.36 The passage is mainly concemed withA the modes of thinking that are used by technologistsB the importance of nonverbal thinking in engineering designC the new role for nonscientific thinking in engineeringD the difference between the goals of engineers and those of technologists37 Which of the following is NOT mentioned as an example involving nonverbal thinking in paragraphs 1 and 2?A Building cathedralsB Creating rocketsC Designing diesel enginesD Making boats38 The example of the diesel engine is used in the passage to illustrate thatA errors in engineering design are unavoidableB the nonscientific component design is primaryC mathematics is a necessary part of the study of designD design courses form a part of engineering curricula39 It can be inferred that the writer thinks that engineering curricula areA strengthened when they include courses in designB weakened by the courses designed to develop mathematical skillsC weak because they include some nonscientific componentsD strong despite the absence of nonscientific modes of thinking?40 What contributes to random failures in automatic control systems?A Using too many inexperienced engineers in the fieldB Attaching too much importance to nonverbal thinking in engineering.C Relying too heavily on the role of mathematics in designD Depending very little on verbal mathem
