34、ns.,,可知，漲潮時(shí)(潮差超過(guò)10米)的海灣和河口通常是建造潮汐發(fā)電站的理想地點(diǎn)。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(jī)，每個(gè)渦輪機(jī)上都有一個(gè)發(fā)電機(jī)。漲潮時(shí)，水通過(guò)大壩，渦輪轉(zhuǎn)動(dòng)，發(fā)電機(jī)工作，產(chǎn)生電力。退潮時(shí)，水流通過(guò)大壩流出，渦輪再次轉(zhuǎn)動(dòng)。所以turbine是讓發(fā)電機(jī)工作的機(jī)器。故選B。 3. 推理判斷題。A：我們可以用它來(lái)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(shí)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(shì)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(chǔ)存起來(lái)，并用于持續(xù)發(fā)電。結(jié)合選項(xiàng)，故選C。 4. 細(xì)節(jié)理解題。A：挖掘更多的海灣和河口。B：通過(guò)建造更便宜的潮汐發(fā)電站。C：通過(guò)關(guān)閉傳統(tǒng)電力。 D：利用潮汐能來(lái)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(xiàng)，故選B。 TherearcsomeinterestingfactsabouttheNile. ? TheNileisnearly6,671kilometerslong.Itisbelievedtobethelongestriverintheworld. ?

42、magazine. 【答案】5.C6.A7.D8.C9.D【解析】本文是說(shuō)明文。短文介紹了世界上最長(zhǎng)的河流尼羅河的自然地理和人文概況。尼羅河長(zhǎng)6,671千米，從南向北流經(jīng)9個(gè)國(guó)家，注入地中海。尼羅河對(duì)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(xì)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(gè)

43、國(guó)家。故選C。 5. 細(xì)節(jié)理解題根據(jù)第四段TheNiledeltainthenorthofEgyptiswheretheNileflowsintotheMediterraneanSea.尼羅河在位于埃及北部的尼羅河三角洲流入地中海，可知選A。 6. 數(shù)據(jù)計(jì)算題。根據(jù)HalfofEgypt'spopulation一around40,000.000peopleliveintheNileDeltaarea.—句可知，居住在尼羅河三角洲的人口占埃及人口的-半，所以埃及的總?cè)丝谑?0.000.000的兩倍，即80,000.000o故選D。 8..細(xì)節(jié)理解題根據(jù)Itplayedakeyroleinu

44、nderstandingEgyptianhieroglyphics.可知,thefamousRosettastone在理解埃及象形文字方面起重要作用。故選Co推理判斷題。分析短文內(nèi)容可知，本文是一篇介紹尼羅河流域概況白然科學(xué)文章，所以它可能來(lái)自一本科學(xué)雜志。故選D。 3 Inthemodernage,humansocietyrunsonenergy.Mostmachinesneedelectricitytooperate.Humanscannotlivewithoutelectricityevenasingledayintheirdailylifeandwork.Theyhavemanyd

52、大多數(shù)機(jī)器需要電力才能運(yùn)轉(zhuǎn)。人類在日常生活和工作中沒(méi)有電,甚至一天都無(wú)法生存。因此人們用能源使世界運(yùn)轉(zhuǎn)，故選B。 10. 細(xì)節(jié)理解題。根據(jù)"Forexample,fossilfuels（化石燃料）arethemostcommonkindofenergy.Theyincludecoakoil,andnaturalgas.First,peoplehavetodigthemfromtheground''.可知，化石燃料從地里挖出來(lái)的，故選A。 11. 細(xì)節(jié)理解題?根據(jù)"Butsomekindsoftidalenergycankillmanyfishandotherseaanimals".可知，一

53、些潮汐能殺死許多魚類和其他海洋動(dòng)物。故選D。 12. 推理判斷題。根據(jù)"Nuclear（核）energyisaverypowerfulformofenergy.Itischeap.Itisalsoveryclean".可知，核能源是一個(gè)非常強(qiáng)大的能量形式，它是便宜的，它也很干凈，因此人們喜歡它。故選C。 13. 推理判斷題。根據(jù)"Theyhavemanydifferentwaystocreateelectricity.Butsomewaysareharmfultotheenvironment”.可知，本文主要介紹了幾種發(fā)電的方式，因此與科學(xué)有關(guān)，故選B。 4 Theoceancanbe
