1 班级 学 姓名装 订 纸Final Exam of College EnglishBand IV Paper II. Reading Comprehension (Skimming and Scanning) (10%)Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1. For questions 1-7, choose the best answer from the four choices marked A), B), C) and D). For questions 8-10, complete the sentences with the information given in the passage.How Exercise WorkWhen you exercise or compete in sports, you notice several things about your body. You breathe heavier and faster, your heart beats faster, your muscles hurt and you sweat. These are all normal responses to exercise, whether you work out regularly or only once in a while, whether you are a “weekend warrior” or a trained athlete . When you watch world-class athletes compete, you see the same responses, only magnified.The body has an incredibly complex set of processes to meet the demands of working muscles. Every system in the body is involved. In this article, we will look at how your body responds to strenuous exercise — how muscles, blood circulation, breathing and body heat are affected. You will also see how these responses can be enhanced by training. Your Body’s Response to ExerciseAny type of exercise uses your muscles. Running, swimming, weightlifting — any sport you can imagine — uses different muscle groups to generate motion. In running and swimming, your muscles are working to accelerate your body and keep moving. In weightlifting, your muscles are working to move a weight. Exercise means muscle activity!As you use your muscles, they begin to make demands on the rest of the body. In strenuous exercise, just about every system in your body either focuses its efforts on helping the muscles do their work, or shuts it down. For example, your heart beats fast during strenuous exercise so that it can pump more blood to the muscles, and your stomach shuts down during strenuous exercise so that it does not waste energy that the muscles can use.When you exercise, your muscles act something like electric motors. Your muscles take in a source of energy and they use it to generate force. An electric motor uses electricity to supply its energy. Your muscles are biochemical motors, and they use a chemical called adenosine triphosphate (ATP) for their energy source. During the process of “burning” A TP, your muscles need three things:They need oxygen, because chemical reactions require ATP and oxygen consumed to produce oxygen.They need to eliminate metabolic wastes (carbon dioxide, lactic acid) that the chemical reactions generate.They need to get rid of heat. Just like an electric motor, a working muscle generates heat that it needs to get rid of.In order to continue exercising, your muscles must continuously make ATP. To make this happen, your body must supply oxygen to the muscles and eliminate the waste products and heat. The more strenuous the exercise, the greater the demands of working muscle. If these needs are not met, then exercise will cease — that is, you become exhausted and you won't be able to keep going.To meet the needs of working muscle, the body has all orchestrated response, involving the heart, blood vessels, nervous system, lungs, liver and skin. It really is all amazing system! Exercise and ATPFor your muscles — in fact, for every cell in your body — these source of energy that keeps everything going is called ATP. Adenosine triphosphate (ATP) is the biochemical way to store and use energy.The entire reaction that turns ATP into energy is a bit complicated, but here is a good summary: Chemically, ATP is all adenine nucleotide bound to three phosphates.There is a lot of energy stored in the bond between the second and third phosphate groups that can be used to fuel chemical reactions.When a cell needs energy, it breaks this bond to form adenosine diphosphate (ADP) and a free phosphate molecule.In some instances, the second phosphate group can also be broken to form adenosine monophosphate: (AMP).When the cell has excess energy, it stores this energy by forming ATP from ADP and phosphate.ATP is required for the biochemical reactions involved in any muscle contraction. As the work of the muscle increases, more and more ATP gets consumed and must be replaced in order for the muscle to keep moving.Because ATP is so important, the body has several different systems to create ATP. These systems work together in phases. The interesting thing is that different forms of exercise use different systems, so a sprinter is getting ATP in a completely different way from a marathon runner!ATP comes from three different biochemical systems in the muscle, in this order: Phosphagen system;Glycogen —lactic acid system; Aerobic respiration.2 班级 学 姓名装 订 纸Exercise and the Phosphagen SystemA muscle cell has some amount of A TP floating around that it can use immediately, but not very much only enough to last for about three seconds. To replenish the ATP levels quickly, muscle cells contain a high-energy phosphate compound called creatine phosphate. The phosphate group is removed from creatine phosphate by an enzyme called creatine kinas, and is transferred to ADP to form ATP. The cell turns ATP into ADP, and the phosphagen rapidly turns the ADP back into A TP. As the muscle continues to work, the creatine phosphate levels begin to decrease. Together, the A TP levels and creatine phosphate levels are called the phosphagen system. The phosphagen system can supply the energy needs of working muscle at a high rate, but only for 8 to 10 seconds. Exercise and the Glycogen-Lactic Acid SystemMuscles also have big reserves of a complex carbohydrate called glycogen. Glycogen is a chain of glucose molecules. A cell splits glycogen into glucose. Then the cell uses anaerobic metabolism (anaerobic means “without oxygen”) to make ATP and a byproduct called lactic acid from the glucose.About 12 chemical reactions take place to make ATP under this process ,so it supplies ATP at a slower rate than the phosphagen system. The system can still act rapidly and produce enough ATP to last about 90 seconds. This system does not need oxygen, which is handy because it takes the heart and lungs some time to get their act together. It is also handy because the rapidly contracting muscles off its own blood vessels depriving itself of oxygen-rich blood.There is a definite limit to anaerobic respiration because of the lactic acid. The acid is what makes your muscles hurt. Lactic acid builds up in the muscle tissue and causes the fatigue and soreness you feel in your exercising muscles.Exercise and Aerobic RespirationBy two minutes of exercise, the body responds to supply working muscles with oxygen. When oxygen is present, glucose can be completely broken down into carbon dioxide and water in a process called aerobic respiration. The glucose can come from three different places:Remaining glycogen supplies in these muscles;Breakdown of the liver's glycogen into glucose, which gets to working muscle through the bloodstream;Absorption of glucose from food into intestine, which gets to working muscle through the bloodstream.Aerobic respiration can also use fatty acids from fat reserves in muscle and the body to produce A TP. In extreme cases (like starvation), proteins can also be broken down into amino acids and used to make ATP. Aerobic respiration would use carbohydrates first, then fats and finally proteins, if necessary. Aerobic respiration takes even more chemical reactions to produce A TP than either of the above systems. Aerobic respiration produces ATP at the slowest rate of the three systems, but it can continue to supplyATP for several hours or longer, so long as the fuel supply lasts. What Happens When You ExerciseSo imagine that you start running. Here’s what happens:The muscle cells bum off the ATP they have floating around in about 3 seconds.The phosphagen system kicks in and supplies energy for 8 to 10 seconds. This would be the major energy system used by the muscles of a 100-meter sprinter or weight lifter, where rapid-acceleration, short-duration exercise occurs.If exercise continues longer, then the glycogen-lactic acid system kicks in. This would be true for short-distance exercises such as a 200-or 400-meter dash or 100-meter swim.Finally, if exercise continues, then aerobic respiration takes over. This would occur in endurance events such as an 800-meter dash, marathon run, rowing, cross —country skiing and distance skating.When you start to look closely at how the human body works, it is truly an amazing machine!注意: 此部分1-7题请在答题卡上回答,8-10题请在Paper Two 上回答。

They hit one another hard. At the start they only fight with their fists. But soon they begin hitting one another over the heads with chairs. And so it goes on until one of the men crashes (撞击) through a window and falls thirty feet to the ground below. He is dead!Of course he isn't really dead. With any luck he isn't even hurt. Why? Because the men who fall out of high windows or jump from fast moving trains, who crash cars of even catch fire, are professionals. They do this for a living. These men are called stuntmen. That is to say, they perform tricks.There are two sides to their work. They actually do most of the things you see on the screen. For example, they fall from a high building. However, they do not fall on to hard ground but on to empty cardboard boxes covered with a mattress (床垫). Again, when they hit one another with chairs, the chairs are made of soft wood and when they crash through windows, the glass is made of sugar!But although their work depends on trick of this sort, it also requires a high degree of skill and training. Often a stuntman' s success depends on careful timing. For example, when he is "blown up" in a battle scene, he has to jump out of the way of the explosion just at the right moment.Naturally stuntmen are well paid for their work, but they lead dangerous lives. They often get seriously injured, and sometimes killed. A Norwegian stuntman, for example, skied over the edge of a cliff (悬崖) a thousand feet high. His parachute (降落伞) failed to open, and he was killed. In spite of all the risks, this is no longer a profession for men only. Men no longer dress up as women when actresses have to perform some dangerous action. For nowadays there are stuntgirls tool1. Stuntmen are those who ______.A. often dress up as actorsB. prefer to lead dangerous livesC. often perform seemingly dangerous actionsD. often fight each other for their lives2. Stuntmen earn their living by ______.A. playing their dirty tricksB. selling their special skillsC.jumping out of high windows3D. jumping from fast moving trains3. When a stuntman falls from a high building, ______.A.he needs little protectionB. he will be covered with a mattressC.his life is endangeredD. his safety is generally all right4. Which of the following is the main factor (因素) of a successful performance?A. Strength.B. Exactness.C. Speed.D. Carefulness.5. What can be inferred from the author' s example of the Norwegian stuntman?A.Sometimes an accident can occur to a stuntman.B.The percentage of serious accidents is high.C.Parachutes must be of good quality.D. The cliff is too high.Passage 2In Japan’s capital city of Tokyo, earthquake danger limits(限制)the height of buildings. The city has spread out so far and the traffic has become so heavy that it is very difficult to go from one place to another. The price of the land, too, has skyrocketed. All these explains why a group of Japanese land developers came to the conclusion(结论)that there was nowhere to go but down. So far they have dug out space underground for fifteen shopping centres.What are some of the advantages(优势)of shopping and eating underground? Clean air is one of them. The city of Tokyo has one of the most serious smog problems in the world. Another advantage is that you escape the ever-present threat(威胁)of traffic accidents on the city’s busy streets. Still another is the convenience(便利)of getting around: you are usually right next to, or even in, a subway station. And you can even spend the night underground if you like. The Kyobashi station, for example, in downtown Tokyo, has a hotel with a bar, restaurant, and barbershop.6. The reason why buildings can not be very high in Tokyo is ____.A. that the information about high buildings is limited in TokyoB. that the workers haven’t mastered enough modern science and technology4C. the earthquakeD. the heavy traffic7.

Passage 1History and Development of mechanical engineeringApplications of mechanical engineering are found in the records of many ancient and medieval societies throughout the globe. In ancient Greece, the works of Archimedes (287 BC - 212 BC) and Heron of Alexandria (10 -70 AD) deeply influencedmechanics in the Western tradition. In China, Zhang Heng (78 - 139 AD) improved a water clock and invented a seismometer, and Ma Jun(200 - 265AD) invented a chariot with differential gears.During the years from the 7th to the 15th century, there were remarkable contributions from Arabians in the field of mechanical technology. Al Jaziri, who was one of them, wrote his famous “Book of Knowledge of lngenious Mechanical Devices“ in 1206 in which he presented many mechanical designs. He is also considered to be the inventor of such mechanical devices that now form the very basics of mechanisms, such as crank and cam shafts.During the early 19th century in England and Scotland, the development of machine toolsled mechanical engineering to develop as a separate field within engineering, providing manufacturing machines and the engines to power them. The first British professional society of mechanical engineers was formed in 1847,thirty years after civil engineers formed the first such professional society. In the United Slates, the American Society of Mechanical Engineers (ASME) was formed in 1880, becoming the third such professional engineering society, after the American Society of Civil Engineers(1852) and the American Institute of Mining Engineers (1871 ).The first school in the United States to offer an engineering education was the United States Military Academy in 1817. Education in mechanical engineering has historically been based on a strong foundation in mathematics and science.The field of mechanical engineering is considered among the broadest of engineering disciplines. The work of mechanical engineering ranges from the depths of the ocean to outer space.31. Which of the following country is not mentioned by the author in records of ancient and medieval societies where applications of mechanical engineering are found?A. GreeceB. ChinaC. Arabian countriesD. England32. who is considered to be the inventor of mechanical devices that form the basics of mechanism?A. Al JaziriB. Ma JunC. ArchimedesD. Zhang Heng33. In which of the following countries was the first professional society of mechanical engineers established?A. United StatesB. The Great BritainC. GreeceD. China34. In which year did the British form the first professional society like the British society of mechanical engineers?A. 1847B. 1817C. 1877D. 187435. Which of the following statements is true, according to the passage?A. Mechanical engineering is a new discipline rather than an old one.B. Al Jaziri is the inventor of crank and cam shaft.C. Education in mechanical engineering has been based on a strong foundation of mathematics and science.D. Mechanical engineering has nothing to do with oceans or outer space.Passage 2Engineering materialsCommon engineering materials are normally classified as metals and nonmetals. Metals may conveniently be divided into ferrous and non-ferrous metals.Important ferrous metals for the present purpose are:(i) Cast iron.(ii) Wrought iron.(iii) Steel.Ferrous MaterialsCast iron: It is an alloy of iron, carbon and silicon and it is bard and brittle.Carbon content may be within 1.7% to 3% and carbon may be present as free carbon or iron carbide Fe3C.Wrought iron: This is a very pure iron where the iron content is of the order of 99. 5%. It is produced by re-melting pig iron and some small amount of silicon, sulphur, or phosphorus may be present. It is tough, malleable and ductile and can easily be forged or welded. It cannot however take sudden shock. Chains, crane books, railway couplings and such other components may bemade of this iron.Steel: This is by far the most important engineering material and there is an enormous variety of steel to meet the wide variety of engineering requirements. Steel is basically an alloy of iron and carbon in which the carbon content can be less than 1.7% and carbon is present in the form of iron carbide to impart hardness and strength. Two main categories of steel are plain carbon steel and alloy steel.(i) Plain carbon steel: The properties of plain carbon steel depend mainly on the carbon percentages and other alloying elements are not usually present in more than 0. 5% to 1%, such as 0.5% Si or 1% MD, etc.(ii) Alloy steel: these are steels in which elements other than carbon are added in sufficient quantities to impart desired properties, such as wear resistance, corrosion resistance, electric or magnetic properties. Chief alloying elements added are usually nickel for strength and toughness, chromium for hardness and strength, tungsten for hardness at elevated temperature, vanadium for tensile strength, manganese for high strength in hot rolled and heat treated condition, silicon for high elastic limit.36. Which of the following dose not belong to the group of ferrous metals?A. Cast ironB. Wrought ironC. BronzeD. Steel37. Which of the following is not included as a component for producing wrought iron?A. SiliconB. SulphurC. PhosphorousD. Zinc38. which is the most important engineering material, according to the passage?A. Cast ironB. SteelC. Wrought ironD. Aluminium39. According to the passage, what quality will be imparted when carbon is added to iron?A. StrengthB. ResilienceC. ElasticityD. Plasticity40. which of the following statements is true according to thepassage?A. In cast iron the carbon content may be more than 3.7%B. Wrought iron is tough, malleable and ductile and can not be forged or welded.C. In steel carbon is present in the form of iron carbideD. In plain carbon steel, except for carbon, other alloying elements are usually present in more than 0. 5% to 1%.Passage 3HydraulicsThe word “hydraulics” generally refers to power produced by moving liquids. Modern hydraulics is defined as the use of confined liquid to transmit power, multiply force, or produce motion. Though hydraulic power in the form of water wheels and other simple devices has been in use for centuries, the principles of hydraulics weren’t formulated into scientific law until the 17th century. It was then that French philosopher Blaise Pascal discovered that liquids cannot be compressed. He discovered a law which states: Pressure applied on a confined fluid is transmitted in all directions with equal force on equal areas.Hydraulic systems contain the following key components.Fluid - can be almost any liquid. The most common hydraulicfluids contain specially compounded petroleum oils that lubricate and protect the system from corrosion.Reservoir or tank - acts as a storehouse for the fluid and a heat dissipater.Hydraulic pump - converts the mechanical energy into hydraulic energy by forcing hydraulic fluid, under pressure, from the reservoir into the system.Fluid lines or pipes - transport the fluid to and from the pump through the hydraulic system. These lines can be rigid metal tubes, or flexible hose assemblies. Fluid lines can transport fluid under pressure or vacuum (suction).Hydraulic valves - control pressure, direction and flow rate of the hydraulic fluid.Actuator - converts hydraulic energy into mechanical energy to do work. Actuators usually take the form of hydraulic cylinders. Hydraulic cylinder are used on agricultural, construction, and industrial equipment.In actual hydraulic systems, Pascal‘s law defines the basis of the results which are obtained from the system. Thus, a pump moves the liquid in the system. The intake of the pump is connected to the reservoir or tank, atmospheric pressure,pressing on the liquid in the reservoir, forces the liquid into the pump. When the pump operates, it forces liquid from the tank into the discharge pipe at a suitable pressure. The flow of the pressurized liquid discharged by the pump is controlled by valves. These control functions are used in most hydraulic systems: 1 control of the liquid pressure, 2 control of the liquid flow rate, and 3 control of the direction of flow of the liquid.Hydraulic drives are used in preference to mechanical systems when 1 power is to be transmitted between points too far apart for chains or belts; 2 high torque at low speed is required;3 a very compact unit is needed;4 a smooth transmission, free of vibration, is required;5 easy control of speed and direction is necessary; and6 output speed is varied steplessly.41. when was the principles of hydraulics formulated into science laws?A. In 15th centuryB. In 16th centuryC. In 17th centuryD. In 18th century42. In which way can fluid lines transport fluid?A. under pressureB. Under vacuumC. both under pressure and vacuumD. not given43. The operation of which of the following componentswould force the liquid from the tank to the discharge pipes?A. PumpB. ValveC. ActuatorD. Reservoir or tank44. which of the following components of a hydraulics system controls the flow of the pressurized liquid discharged by the pump?A. Reservoir or tankB. Fluid lines or pipesC. ValvesD. Actuator45. Hydraulic drives are used in preference to mechanical systems whenA. Power is to be transmitted between close pointsB. high torque at high speed is requiredC. Easy control of speed and direction is not necessaryD. Output speed is varied steplessly.Passage 4V-beltThe rayon and rubber V-belt are widely used for power transmission. Such belts are made in two series: the standard V-belt and the high capacity V-belt. The belts can be used with short center distances and are made endless so that difficulty with splicing devices is avoided.First, cost is low, and power output may be increased byoperating several belts side by side. All belts in the drive should stretch at the same rate in order to keep the load equally divided among them. When one of the belts breaks, the group must usually be replaced. The drive may be inclined at any angle with tight side either top or bottom. Since belts can operate on relatively small pulleys, large reductions of speed in a single drive are possible.Second, the included angle for the belt groove is usually from 34°to 38°.The wedgingaction of the belt in the groove gives a large increase in the tractive force developed by the belt.Third, pulley may be made of cast iron, sheet steel, or die-cast metal. Sufficient clearance must be provided at the bottom of the groove to prevent the belt from bottoming as it becomes narrower from wear. Sometimes the larger pulley is not grooved when it is possible to develop the required tractive force by running on the inner surface of the belt. The cost of cutting the grooves is thereby eliminated. Pulleys are on the market that permit an adjustment in the width of the groove. The effective pitch diameter of the pulley is thus varied, and moderate changes in the speed ratio can be secured.46. why are belts made endless?A. To reduce costB. easier to manufactureC. To avoid splicing devicesD. To produce bigger tractive force47. why is large reductions of speed in a single V-belt drive possible?A. Because pulleys are very bigB. Because V-belt can produce large tractive forceC. Because belts can operate on large pulleysD. Because belts can operate on small pulleys48. what can V-belt be made of?A. SteelB. RayonC. PlasticD. Iron49. When one of the belts breaks, what should be done?A. NothingB. Replace the broken one with another oneC. Replace the belt groupD. Break another one50. which of the following statements is true, according to the passage?A. Power output may be decreased by operating several belts side by sideB. The drive may be inclined at any angle with tight side either top or bottomC. sometimes the smaller pulley is not grooved when it is possible to develop the required tractive force by running on the inner surface of the belt.D. Pulleys are on the market that permit an adjustment in the depth of the groove.三、汉英翻译(30’)把以下句子括号内的中文翻译成英语,写在答题卡上1.
