18.Think about the different ways that people use wind.You can use it to fly a kite or to sail a boat.Wind is one of our cleanest and richest power sources,as well as one of the oldest.Evidence shows that windmills(風(fēng)車) began to be used in ancient Iran back in the seventh century BC.They were first introduced to Europe during the 1100s,when armies returned from the Middle East with knowledge of using wind power.
For many centuries,people used windmills to grind(磨碎) wheat into flour or pump water from deep underground.When electricity was discovered in the late 1800s,people living in remote areas began to use them to produce electricity.This allowed them to have electric lights and radio.However,by the 1940s when electricity was available to people in almost all areas of the United States,windmills were rarely used.
During the 1970s,people started becoming con cerned about the pollution that is created when coal and gas are burned to produce electricity.People also realized that the supply of coal and gas would not last forever.Then,wind was rediscovered,though it means higher costs.Today,there is a global movement to supply more and more of our electricity through the use of wind.
24.From the text we know that windmillsC.
A.have rarely been used since electricity was discovered
B.have a history of more than 2,800 years

D.were invented by European armies
25.What was a new use for wind power in the late 19gh century?C
A.Sailing a boat.
B.Grinding wheat into flour.
C.Producing electricity.
D.Pumping water from underground.
26.One of the reasons wind was rediscovered in the 1970s is thatB.
A.it is one of the oldest power sources
B.wind power is cleaner
C.it was cheaper to create energy from wind
D.the supply of coal and gas failed to meet needs
27.What would the author probably discuss in the paragraph that follows?B
A.The advantages of wind power.
B.The global trend towards producing power from wind.
C.The worldwide movement to save energy.
D.The design of wind power plants.
分析 本文介紹了風(fēng)能及風(fēng)能運用的情況.在能源短缺的今天,作為最為潔凈、豐富的風(fēng)能,一定會對我們的生活作出極大的貢獻(xiàn).
解答 CCBB
24.C 細(xì)節(jié)理解題.根據(jù)第二段的第二句"When electricity was discovered in the late 1800s.people living in remote areas began to use them to produce electricity.This allowed them to have electrie lights and radio."可知,十九世紀(jì)末有了電之后,偏僻地區(qū)的人們就利用風(fēng)車發(fā)電,于是人們就有了電燈和收音機,因此選擇C項.根據(jù)第一段的"…windmills began to be used in ancient Iran back in the seventh century BC"可知,A項錯誤;B項錯在more than;根據(jù)末段句子可知,盡管成本較高,人們依然使用風(fēng)能提供電力,因此D項錯誤.
25.C 細(xì)節(jié)理解題.根據(jù)第二段句子"When electricity was discovered in the late 1800s,people living in remote areas began to use them to produce electricity."可知,人們最初利用風(fēng)車磨面或抽水,十九世紀(jì)末有了電之后,人們又用其發(fā)電,因此選擇C項.
26.B 推理判斷題.根據(jù)最后一段"people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity"可知,二十世紀(jì)七十年代,人們注重環(huán)保,而且認(rèn)識到煤和氣的短缺;而風(fēng)能的特點是潔凈、豐富和歷史悠久,但是成本較高.綜合選擇B項最佳.
27.B 推理判斷題.根據(jù)末段句子"Today,there is a global movement to supply more and more of our electricity through the use of wind"可知:現(xiàn)在全球已越來越多地使用風(fēng)力發(fā)電,所以下一段應(yīng)該要進(jìn)一步推廣使用風(fēng)力發(fā)電,這是一種總體的能源發(fā)展趨勢.接下來作者應(yīng)該談?wù)摾蔑L(fēng)能發(fā)電的情況,因此選擇B項.
點評 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力,做細(xì)節(jié)理解題時一定要找到文章中的原句,和題干進(jìn)行比較,再做出正確的選擇.在做推理判斷題不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進(jìn)行合乎邏輯的推理判斷.
