34、ns.,,可知，漲潮時(潮差超過10米)的海灣和河口通常是建造潮汐發(fā)電站的理想地點。故選C。 2. 推理判斷題。分析第三段中Tnthedamarcmanyturbinesandoneachturbinethereisanelectricgenerator.Whenthetiderises,watercomesthroughthedam,theturbinesturnandtheelectricgeneratorswork,producingelectricity.Whenthetidefall,watergoesoutthroughthedam,theturbinesturnagain."可

35、知，水壩里有許多渦輪機，每個渦輪機上都有一個發(fā)電機。漲潮時，水通過大壩，渦輪轉(zhuǎn)動，發(fā)電機工作，產(chǎn)生電力。退潮時，水流通過大壩流出，渦輪再次轉(zhuǎn)動。所以turbine是讓發(fā)電機工作的機器。故選B。 3. 推理判斷題。A：我們可以用它來獲取有用的潮汐。B：它可以改善海洋環(huán)境。C：我們幾乎可以隨時使用它。D：滿足16.4%的電力需求。根據(jù)第四段^h^Usingtidalenergytoproduceelectricityismuchcheaperthanusingthetraditionalenergy,likecoalorgas."和“Inaddition,withthedevelopmentof

36、moderntechnology,tidalenergycanbestoredandusedtoproduceelectricitycontinuously.''可知，潮汐發(fā)電的優(yōu)勢一是利用潮汐能發(fā)電比 使用煤炭或天然氣等傳統(tǒng)能源要便宜得多；二是隨著現(xiàn)代技術(shù)的發(fā)展，潮汐能可以被儲存起來，并用于持續(xù)發(fā)電。結(jié)合選項，故選C。 4. 細節(jié)理解題。A：挖掘更多的海灣和河口。B：通過建造更便宜的潮汐發(fā)電站。C：通過關(guān)閉傳統(tǒng)電力。 D：利用潮汐能來替代其他能源。根據(jù)第二段中"Tomakeuseoftidalenergy,weneedtobuildtidalpowerstations/'可知，為了利用

37、潮汐能，我們需要修建潮汐能電站。結(jié)合選項，故選B。 TherearcsomeinterestingfactsabouttheNile. ? TheNileisnearly6,671kilometerslong.Itisbelievedtobethelongestriverintheworld. ?

42、magazine. 【答案】5.C6.A7.D8.C9.D【解析】本文是說明文。短文介紹了世界上最長的河流尼羅河的自然地理和人文概況。尼羅河長6,671千米，從南向北流經(jīng)9個國家，注入地中海。尼羅河對于埃及很重要，一半的埃及人口居住在尼羅河三角洲。197（）年建成的阿斯旺大壩有助于控制尼羅河洪水。 4. 細節(jié)理解題根據(jù)第二段Itliesinthefollowingcountries:Kenya,Eritrea,Congo,Burundi,Uganda,Tanzania,Rwanda,Egypt,Sudan,RepublicofSouthSudanandEthiopia.可知，尼羅河流經(jīng)9個
