8、n supply 1 of the global energy consumption. （分数：1.00）填空项 1:_ （正确答案：less than 1%）解析：Wind power is produced by using wind generators to harness the kinetic energy of wind. It is gaining worldwide popularity as a large scale energy source, although it still only provides less than one percent of globa

9、l energy consumption. Weve used the wind as an energy source for a long time. The Babylonians and Chinese were using wind power to pump water for irrigating crops 4,000 years ago, and sailing boats were around long before that. Wind power was used in the Middle Ages, in Europe, to grind corn, which

It is one of the largest forms of Green Energy used in the world today. Here are s

12、everal advantages of wind farms. One of the greatest advantages is that it is ample. Secondly, it is renewable. Some other advantages are that it is widely distributed, cheap, and also helps in reducing toxic gas emissions. Along with economy, it is also said to diminish the greenhouse effect. Also,

13、 it generates no pollution. However, there are some disadvantages which may put a damper in its popularity. Though the costs of creating it are going down, even today a large number of turbines have to be built to generate a proper amount. Though wind power is non-polluting, the turbines may create

14、a lot of noise, which indirectly contributes to noise pollution. Wind can never be predicted. Even the most advanced machinery may come out a cropper while predicting weather and wind conditions.填空项 1:_ （正确答案：toxic/poisonous gas）解析：填空项 1:_ （正确答案：turbines）解析：填空项 1:_ （正确答案：noise pollution）解析：三、风力发电的利用

MAN: A report about wind energy. You know that wind power, as an alternative to

16、 fossil fuels, is plentiful, renewable, clean and produces no greenhouse gas emissions during operation and uses little land. It is attractive. woman: Yes. It has gained more and more popularity among researchers. MAN: Yeah. As estimated in 2010, wind energy production was over 2.5% of worldwide pow

17、er, growing at more than 25% per annum. woman: Well, that number has increased in recent years. The wind energy has met about 3% of global electricity generation. In some places, it can supply 2/3 of the energy needs. While in Esperence, it can cover half of the energy consumed. MAN: Wow. Amazing! I

18、t is really good for the global economy, right? woman： Of course.(2).In Esperence, wind energy accounts for _ of the total energy consumption. （分数：1.00）A.3%B.67%C.50% 解析：四、螺旋桨(总题数：1，分数：3.00)Listen to the conversation and complete the following sentences with NO MORE THAN TWO WORDS（分数：3.00）(1).The pr

19、opeller usually contains a(n) 1 that drives a machine.（分数：1.00）填空项 1:_ （正确答案：impeller head）解析：MAN: Do you know propeller which is an indispensable part of a wind generator? woman: Yes. its said that without it, electricity cannot be generated. MAN: Yeah. It is a mechanical device that converts wind

20、energy into a rotational motion to produce work. It typically consists of an impeller head that drives a machine through a gear box. woman: Yes. And usually it is very large to extract energy from the largest possible volume of air. The larger the propellers are, the more electricity they can make.

21、MAN: Yeah, you are right. Sometimes it is about the same size as the plane. woman: Wow. So large! Do you know where they are usually made? MAN: Well. A lot of country now can develop this technology independently, such as America, China and South Korea. But for the wind farm near our village, the pr

Do you know what kind of places would be suitable areas for wind fa

24、rm? woman: En. As far as I know, the best places for wind farms are in coastal areas, at the tops of rounded hills, open plains and gaps in mountainsplaces where the wind is strong and reliable. MAN: Yeah. But most of the wind turbines in the United States are probably located on farm land or near f

25、arm land. In this case, would the farmers receive any compensation? woman： Well. In many parts of the country, farmers who allow wind turbines to be built on their land are compensated by the utility company for the use of the land. man： How much will they get? woman： A farmer who signs a contract f

26、or the installation of a wind turbine on his farm land will typically receive two types of payments. The initial payments are a lease of the development right for the land. This option lease pays two to ten dollars per acre to the farmer. man： Then whats the other type of payment? woman： The other p

27、ayments are based on the electricity produced by the turbine after the wind turbines are built. One option is an annual payment based on the rated capacity of the turbine. Another is a flat annual payment per turbine. man： I see. Well, I heard that the government will offer some financial incentives

28、 to promote wind power development? woman； Yes. Both the famers and the companies can get some money from the government.(2).The lease of the development right for the land is paid by _ . （分数：1.00）A.2-10 dollars per acre B.an annual payment based on a percentage of the value of electricity produced

30、e ONE WORD ONLY. （分数：5.00）填空项 1:_ （正确答案：housing）解析：Fans are used to move air (or other gases) in large volume at low gauge pressures. A windmill is a fan in reverse. A fan consists of a wheel or impeller, and a housing. Sometimes the housing is absent, and we have just the impeller, as in an aircraf

31、t propeller. As the technology and popularity of wind power increases, researchers work to find materials that can be used to create longer blades without sacrificing structural integrity. Many materials have been used, both for industrial wind power production and in small domestic applications. Th

32、ese include fiberglass, steel, timber and polymer resin. Take fiberglass as an example. It is generally only used for small, domestic applications, because fiberglass tends to be more fragile than other fiber-based materials. That makes fiberglass a liability for commercial purposes. For this reason

33、, currently, most blades are glass-fiber reinforced plastic (GRP). It has the advantages of being lightweight, which assists in the movement of large rotor blades. It is also stronger than fiberglass, which allows for a wider rotor diameter without risking fractures at high wind speeds.填空项 1:_ （正确答案：timber）解析：填空项 1:_ （正确答案：fragileness）解析：填空项 1:_ （正确答案：lightweight）解析：填空项 1:_ （正确答案：stronger）解析：
