Passage1 Functions of power transmissionThe function of （1）power transmission is to send power from power plants to load center or to exchange power between networks in order to attain the generation-consumption balance or the supply-demand balance between（2）power networks. Power transmission is completed by step-up substations,（3）step-down substations and connected transmission equipment. The transmission line mainly consists of the transmission conductors (4)transmission at high voltage can reduce the line loss and the voltage drop, ensure the power quality, raise the economy of （5）power network operation.The increase of transmission line voltage can not only raise the amount of transmitted power, but also reduce the line loss and line voltage drop, and improve the voltage quality.Passage 2 Substation misoperation and its preventingThe misioeration that can lead to (1) accidents in the electrical operation of the substation mainly are: ○1on-load switching of isolating switch; ○2connecting (2)the grounding wire (closing the grounding switch) with power on; ○3closing the circuit breaker (isolating switch)with ground lines (ground switch) earthed.The “five preventings” for (3) preventing the misoperation in substation includes: ○1preventing the wrong opening or closing of circuit breaker; ○2preventing the on load opening and closing of isolating switch; ○3preventing (4)the closing of grounding switch with power on;○4preventing the closing of circuit breaker with grounding wire connected; ○5preventing(5)the persons from illegal entering the lived bay. Passage 3 A brief introduction on the development of supercritical boilers and their main advantages In (1) some advanced countries such as U.S.A, Japan and European countries, the supercritical boiler has been developed since the 60s of last century. It has been proved by data and experience, the supercritical unit has (2) great advantages on economy and environmental protection. As for its reliability, because the steam-water flow passages in supercritical boiler is same as that in the (3) subcritical once-through boiler, there isn’t anything special, But as far as hydraulic characteristic, a symbol of reliability, is concerned, in a supercritical boiler, under supercritical condition, medium is of single phase and water phase can be avoided. It is admitted that, if (5)whole process management is strengthened,both supercritical and subcritical units can get an excellent reliability index.Passage 4 Steam generation and useSteam is one of man’s dependable servants. More and more in the background, steam is doing more and more work for man. In (1)an electrically heated home steam may be seen only at the teakettle, but the electricity used may be generated by burning coal or gas and producing steam to turn the generator rotors in the power plant. Even if (2) the fuel is uranium and the heat is supplied by nuclear fission, the generation of electricity is still accomplished by(3) first generating steam.In the U.S.A. the demand for electricity doubles every ten years. For the most part water resources suitable for power generation are already in service, except for emergency standby and peak-load units; approximately 90% of (4) the new generating capacity being installed utilizes steam. The (5) use of steam for electric power generation i s expanding in most countries of the world except for the countries where available water power resources are greater than power needs.Passage 5 Circuit breake rCircuit breakers are automatically operated high voltage (or high current) switches. Circuit breakers are required (1) to control electrical power networks by switching circuits on, by carrying load and by switching circuits off under manual or automatic supervision. Their duty is as follows: In closed position the circuit breaker must be a good conductor for the normal load current. In operating the circuit breaker must beable contacts shall have full insulation level. At operation the circuit breaker must close be able (2) to switch the current which can be from a few amperes to many thousands of amperes, and independently of the characteristics from purely inductive to fully capacitive. At closing operation the circuit breaker must close fast and be safe also against full short circuit conditions. They must, therefore, be effective instantaneously when are called upon (3) to perform any switching operation after long periods without movement. As the circuit breaker is the last link in the chain of protective equipment, the circuit breaker reliability is (4)of the highest importance for high reliability of the total electric power system. So the importance (5) of the circuit breaker cannot be over emphasized.Passage 6 The ration of distance to height of pumped-storage power plantFor pumped-storage power plant, generally the ratio of distance to height (1)is used to evaluate topographic condition of power plant. Distance-height ratio (2)is the ration of horizontal distance between upper and low reservoir to the drop between upper and low reservoir that is L/H. The head of simple pumped-storage power plant consists of two parts, they are natural topographic elevation difference and elevation difference formed by dam. Of course, the head derived from topographic elevation difference(3)is most economic, so in selecting plant site, the condition that not only a height difference is available but also no very high dam of upper reservoir is necessary should be considered. Smaller L/H value indicates a shorter water transportation line, then the engineering construction cost can be saved. But in many circumstances, topographic condition (4)is not desirable, so we can’t say the smallest L/H value (5)is the best. In newly constructed three large capacity pumped-storage power plants in our country, the L/H value respectively are: 7.12 in Guangzhou, 4.12 in Shisanling, 2.40 in Tian huangping.Passage 7 Fuel cellsFuel cells are devices that when a fuel such as hydrogen or hydrogen-rich compounds and oxygen are supplied to materials arranged like the anode and cathode of a conventional battery, combine to convert chemical energy directly into electrical energy. Unlike conventional batteries where the conversion of chemical to electrical energy requires only the closing of a circuit between the cathode and anode to produce and electrical current, (1) there is no storage capacity in a fuel cell. These cells require the fuel and oxygen that will produce the chemical reactions that produce an electrical output. Fuel cells have been made that will supply power in the megawatt range, and (2) further development is under way. Such cells are not yet widely used on power systems, but (3) as they are being developed there have been some applications to supply fuel cell power to isolated loads. As the voltage output of a cell is in the order of to 2.5V, (4) many cells are operated in series to obtain voltages and power out put in ranges that are normally required. Inverters are used to (5) supply alternating current from fuel cells when and AC output is desired. Passage 8 Substations pace into the Digital AgeSubstations constitute the main part of power transmission and distribution in a power grid. The substations (1)composed of a large number of primary and secondary equipments,with the responsibility for the electric power transmission and distribution in the grid. Over more than a decade of development, (2) substation automation technology has reached a certain level.In the rebuilding and constructing of power grid in rural and urban areas, automation technology is not only used in low-voltage substations to realize unattended operation, but also in the 220kV and above extra-voltage substations, thus greatly enhancing the level of modernization of power grid construction, strengthening the power transmission and distribution and the possibility of power grid dispatching and reducing the total cost of substation construction, (3)all of which has become an indisputable fact. However, the development of technology is never-ending, and the increasing maturation of technology like intelligent switches,photoelectric current and voltage transformers, online condition monitoring of primary equipments,(4)simulation training technology for substation operation, as well as the development and application of high-speed network in real- time system, is bound to have a profound impact upon the existing substation automation technology, and (5)a full-digital automation system is about to emerge.Passage 9 Overcoming the Problem of WasteMany large cities are anything but beautiful. Streets are littered with trash. In this trash, however, (1) there is still something that can be useful.If people want to solve the problem of waste, (2) there is no time to be lost. They must work out ways of making use of good things which are just thrown away as waste. When a car gets too old, it may not run any more. But if the metal that the car was made of is still good,(it can be put to use again) bottle glass can be ground into sand and used to pave streets. Besides, garbage from food can be changed into fertilizer. But first you have to pick out all the glass and metal.Furthermore, garbage can also be a good source for making building blocks, which are then covered with concrete. Now, (4)more and more machines are designed for this purpose. Some day, people will watch films in a great cinema which has been built out of garbage. Future buildings, roads, and cities may be made from garbage. But so far, (5)building beautiful cities out of garbage is only a dream.Passage 10 HibernationThe weather in winter can be very cold. Some animals sleep during the winter, for it’s difficult for them to find food then. (1)They can sleep for a long tim e. For example, their sleep can last from autumn to spring. (2)We call this kind of sleep in wintertime “hibernation”.Animals need food in winter to keep them warm and alive. If they move about more, they need eat more. (3)Hibernating animals don’t need to eat much because they don’t move. Their heart beats slowly. And they breathe slowly. They find a safe place to sleep. (4)So they don’t need to worry about bad weather and other dangerous animals.In warn winter some animals like bears may wake up. If they see thick no\\snow on the ground, they will get back to their sleep. (5)As it gets warmer and warmer in spring, the sleeping animals begin to wake up and look around for food.Passage 11 SatellitesThe body that is neatest to the Earth is the moon. (1)It circles the Earth and is therefore know as a satellite of the Earth. This satellite is called natural satellite. Man –made spacecraft which circle the Earth are called artificial satellites. Natural as well as artificial satellites circle the planets in a definite path or orbit.(2)A satellite stays in orbit because the planet gravitational force keeps pulling it into a circle.All the bodies in space like the moon, the planets and the stars also exert an attractive force on objects.(3)The bigger and heavier a body is ,the greater is its force of gravity.The moon’s gravitational force is only one-sixth that of the Earth’s. The Earth’s gravitational force of pull keeps us and everything else on Earth from floating away to space.(4)To get out into space we have to overcome the Earth’s gravitational pull.There are many artificial satellites orbiting around the Earth. Some artificial satellites have been sent up to orbit the moon and even the planet Mars.(5)Artificial satellite can be used for various purposes.Passage 12 Secondary equipment in power systemThe secondary equipments in power system are 1.the equipments that provide protecting, monitoring, measuring, regulating, controlling primary equipments, the equipments that supply information, working condition for the operator or maintenance persons, and 2. the equipments that send the commandsignals. The electric circuit connected with the secondary winding of CT or PT is called secondary circuit. The secondary equipment and secondary circuit belong to secondary system.The voltage and 3.current values in secondary system are: 110V, 22V, DC operating voltages, 100 V rated voltage of the potential transformer secondary winding and 4.5A rated current of the current transformer secondary winding. The related parameter values of secondary system after weak electrification are: 24V, 48V, 60V DC operating voltages, 5.50V rated voltage of PT secondary sid e, 0.5A rated current of CT secondary side.Passage 13 Switching overvoltageA sudden change in the configuration of transmission network caused 1.by the operation of a circuit breaker or by the appearance of a fault can cause a rapid surge known as switching overvoltages, which propagates throughout the network. It is these switching overvoltages which in 2.general determine the insulation requirements of transmission lines.Limitating these overvoltages is of extremely importance, because they have an important effect on both 3.the cost of transmission and line failure rate.These switching overvoltages can occur 4.at both opening and closing of circuit breakers. If non-restriking circuit breakers is not used, it is at the instant of closing, and above all, This switching overvoltages is usually limited 5.by means of circuit breaker closing resistor in 500kV system. Passage 14 Transmission line and distribution lineThe high voltage power line through which power is (1)transmitted from power plant’s step-up substation to step-down substation is called power transmission line. The voltage classes of 35kV and above are generally used. High voltage distribution line is (2)the power line that transmits the power from step –down substation to distribution transformers. Low voltage distribution line is the line that transmits power from distribution transformer to the users. The normal voltage of power distribution line is 380V.The special sections of (3)the overhead transmission line refer to the sections with large spanning, serious pollution, (4)lightning frequency happening and heavy raining. The overhead line section whose span is 1000m and longer or the height of the pole or tower is 100m and higher is called (5) large spanning line section.Passage 15 Transformer insulationThe insulation of a transformer can be categorized into internal insulation and external insulation.(1)The internal insulation refers to the insulation of various parts inside the oil tank.The external insulation is the insulation between the upper part of bushings and the ground and the insulation among the bushings. The internal insulation of transformer can be further subdivided into main insulation and longitudinal insulation.(2)The main insulation refers to the insulation between windings and grounding parts and the insulation between windings. The longitudinal insulation refers the insulation between different parts of the same winding, such as insulation between different sections, layers and turns of the same winding.(3)The main insulation materials inside transformer are transformer oil,insulating pressboard, cable paper, corrugated paper, etc. The oil in transformer has two functions, one is insulation, and the other is cooling, (4) The degradation of insulating properties of insulation materials under long period of influence by the factors such as temperature is called insulation aging. (5)If the winding temperature is within the scope of 80-140℃, for every 6℃ temperature rise the insulation life time of the paper used in transformer will decrease by half.Passage 16 The electricity marketThe aim of introducing market mechanism is to bring various parties more economic benefit through equitable competition, thereby promote economic development.Like other markets, it needs (B. a wholesale market) where the sellers and buyers (suppliers) can trade electricity, and needs (D. a retail market ) where the suppliers can sell electricity to final customers. As in other markets, the participants need (A. to agree on the price and quantity to be traded ). Competition is introduced into generation and retail supplied to customers. Customers are free (E. to choose electricity suppliers). .If a customer chooses to buy electricity in the retail market, he should be able to choose electricity supp] y from one of several competing retailers. If a customer decides to purchase directly from the wholesale market, he will need (C. to register as a market customer). Power generation is disaggregated into separate companies to ensure adequate competition.Passage 17 Electric powerElectric power is a most convenient, clean, safe, and useful form of energy which supplies the major portion of energy needs of a modem society. At the present time (C. the lack of electricity (a blackout) ) is newsworthy. Electric power is so vital to the lives of people that (B. its unavailability) causes inconvenience, loss of production, and danger to many individuals who are in operation (such as cardiac operation) in hospital. A prolonged blackout, which is inevitable when a growing load is combined with no generation additions, could lead to (D. social disorder, and even national tragedy). With the developing of industry and improving in living standard, the electric power demand is growing continuously and (A. its growth rate) is much greater than that of all other forms of energy. Now (E. high electric power consumption per capita) has been one of the indications of modernization of a country.Passage 18 Copyright piracyThere are numerous examples of what has become known as copyright piracy. The American chemical giant Du Pont, for example, recently introduced into one Asian country its famous Londax herbicide, which kills weeds in rice fields. The company invested millions of dollars in (B. the research and development ) of this product and ploughed another US $25 million into opening a local production plant. Les8 than one year later, however, very cheap bottles of Londax were openly on sale. The only difference between (D. the fake and real items )-other than the price-was that the fake was called Rondex and came in a blue rather than a green bottle. However, as it was so much cheaper than the original, it effectively destroyed Du Pont's investment. It also made the company less willing to invest in R&D of (A. new chemicals ). The '·recipe" for Londax should have been treated as (E. the intellectual property ) of Du Pont. Other companies making illegal use of it are stealing just as surely as if they stole Du Pont's machines or any other (C. physical property ) of the inventing company.Passage 19 Electrical energyElectrical energy is the presence and flow of an electric charge. The energy portion ofelectricity is found in a variety of phenomena such as (D. static electricity ), electromagnetic fields and lightning. Hurnans have found the ability to harness these phenomena and store the (E. electrical charge ) forlater use. The concept of (B. electrical energy ) is defined using a variety of different terminologies such as charge, current and potential.Electrical energy is the result of the interaction of subatomic particles with electromagnetic force. Within an atom, electrons and protons create a charge. This charge can be transferred between bodies using direct contact with a conductive material like a wire.The current refers to the movement of the charge. With direct current, this occurs when theelectricity is stored in a battery and travels in one direction out of the battery. (A. Alternating current )occurshen the current changes direction repeatedly within an electrical system. The alternating currentform is usually used to power larger objects such as residences and buildings.(C. Electrical potential) is essential to the range and power of electric energy. When an electric charge exists within an object, a force is exerted from its electrical field. This accelerates the objeet in a direction either towards or away from the charge, depending on the electromagnetic polarization. Generally, positively-charged electricity pushes the object away, while negatively-charged electricity pulls the object towards the field.Passage 20 Solar energyMany people think of alternative solar energy as a new technology, but humans have beenusing this process to heat homes and baths for thousands of years. Alternative solar energy refersto energy from the sun that can be captured and used just like energy created by fossil fuels. Thegreflt benefit of solar energy is that its source, the sun, is not diminished by use of the energy,therefore making this type of power system (A. sustainable ).There are several different methods of collecting and using alternative solar energy. One of(D. the best known is photovoltaic cells ), usually seen as solar panels. Solar panels can be a very good means of collecting solar energy, but do have some drawbacks. While panels have the advantage of quickly turning absorbed solar radiation into usable energy, they are extremely (B. inefficient ). This means that much of the potential power of absorbed light is lost in the transfer process.Thermal solar energy is primarily used to create heat, such as for homes, baths, andswimming pools. In a thermal system, (C. the collected energy is used to heat a fluid), which then passes through a pipe system where it mixes with water, generating steam. Steam is then passed through a turbine system, which turns it into usable energy. Despite sounding like a more complex process than photovoltaic systems use, thermal alternative solar energy is often far more (E. efficient ) and is able to retain and use more of the collected energy directly for heating.Passage 21 Electrical energy conservationElectrical energy conservation refers to the process of reducing} energy used through various means. Many of these methods for (C. reducing energy consumption can be undertaken at home ); turning down the thermostat, tuining off the lights when leaving the room, or switching off power strips when not in use are all examples of this.Homes, businesses or power companies (D. making use of alternative clean energy sources ), such as wind or solar energy, are also examples of electrical energy conservation. Many traditional electrical power plants are coal-fired, which contributes greenhouse gases to the atmosphere, (E. contributing to climate change); this is just one reason that energy conservation is important.For many people, electrical energy conservation begins at home. Not only is this good for the environment, but it can also significantly reduce the amount of a monthly electric bill. Some of the simplest steps to energy conservation include switching traditional light bulbs to compact fluorescent (CFL) bulbs, or (A. turning the thermostat up in the summer and down in the winter ). Making sure appliances are efficient, and that windows and doors are well sealed against the outdoors, are other examples of energy conservation. People (B. looking for other opportnnities for electrical energy conservation in the home) should also look for power strips that can be switched off.。

It cannot be seen or heard, or touched or tasted, even though it exists all around us. There are other things like that. Radio waves are all around us but we cannot detect them, sense them, without a radio receiver. Similarly, we cannot sense radioactivity without a radio detector. But unlike common radio waves, unclear radiation is not harmless to human beings and otherthings.At very high levels, radiation can kill an animal or human being outright by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hurt anything important, the damage may not be significant. This is the case when only a few cells are hit, and if they are killed outright, your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in a deformed way. They can grow into cancer. Sometimes this does not show up for many years.This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can receive radiation and feel fine, then die of cancer five, ten or twenty years later as a result.1.The mystery about nuclear radiation may come from the fact that it cannot bedetected by human senses.A.
