Unit7ProtecttheEarth語法梳理：不行數名詞與情態動詞should精講精練(含答案)不行數名詞解析：依據表示的事物性質的不同，可將名詞分為可數名詞和不行數名詞。可數名詞可以計數，有單復數的區分。而不行數名詞是不行以直接計數的名詞，沒有復數形式。當不行數名詞作主語時，謂語動詞要用第三人稱單數形式。例如：Thesoupistoohot.湯太燙了。不行數名詞可以分為物質名詞和抽象名詞。物質名詞舉例:water,coal,oil,rice等。抽象名詞舉例:homework,time,housework,news等。*有一些不行數名詞表示泛指時是不行數，表示種類時是可數，但含義大多數不發生變化。例如:fruit-fruits,food-foods。一般我們使用它們的不行數形式。有的單詞有時可數，有時不行數，例如chicken和fish作為餐桌上的雞肉、魚肉時，是不行數名詞；作為動物雞、魚時，是可數名詞(同時留意fish作為可數名詞時，單復數同形，只有在強調不同種類的魚時,才用fishes)。不行數名詞前面可以用some，any，alotof等修飾，但不能用many修飾。不行數名詞前還可以用“數詞+單位詞+of”表示數量。例如:acupoftea一杯茶。對不行數名詞的量提問時用howmuch；對不行數名詞前的“單位詞”提問時，疑問詞用howmany。例如:Howmuchteaisthereonthetable?桌上有多少茶?Howmanycupsofteaarethereonthetable?桌上有幾杯茶?【考題精練】一、用所給單詞的適當形式填空。1.Paper(come)fromwood.2.There(be)anyfishinthefridge.Wehavetobuymore.3.Too(many)smoke(make)theairdirty.4.Wecanseesome(milk)intheglass.5.Thewaterinthecup(be)justright,andyoucandrink(they)now.6.Mostofthe(energy)(come)fromcoalandoil.7.I’msothirsty.Iwanttwo(bottle)of(orange)(juice).8.I'mhungry.Iwantsome(rice)and(chicken).9.There(be)muchrubbishinthewater,andthefish(be)dead.10.Therain(keep)thetreesandflowerswet.11.Therearemany(woman)(teacher)inourschool.12.Weshouldn'tusetoo(many)plasticbags,becausetoo(many)plasticisbadfortheEarth.二、單項選擇。()1.Coalisusefulenergy.A.an B.a C./()2.Weshouldn’tdriveoruseplasticbags.A.toomuch;toomany B.toomany;toomuch C.toomuch;toomuch()3.TherecoaloroilonEarth.A.isn'tmany B.isn'tmuch C.ismuch()4.Don’tdrivetoo.Wedon’thaveenergynow.A.near;much B.far;many C.far;much()5.Weshouldreusewaterbecausethere'snotwaterinplaces.A.many;much B.much;many C.much;much情態動詞should的用法AllstudentsAllstudentsshouldknowthis.全部的同學都應當知道這點。用法·情態動詞should表示命令、建議、義務、責任，意為“應當，應當”。·情態動詞should與動詞原形搭配使用，·其否定形式是shouldnot，shouldnot可縮寫為shouldn’t。易錯點提示：should為情態動詞，沒有人稱和數的變化。情態動詞should引導的幾種常見句式：確定句結構：主語+should+動詞原形(+其他).例如：Youshouldsavewater.你(們)應當節省用水。否定句結構:主語+shouldn’t+動詞原形(+其他).例如：Youshouldn’twastewater.你(們)不應當鋪張水。一般疑問句結構：Should+主語+動詞原形(+其他)?例如：Shouldwegotheretonight?我們今晚應當去那里嗎?特殊疑問句結構：特殊疑問詞+should+主語+動詞原形(+其他)?例如：WhatshouldwedotoprotecttheEarth?我們應當做什么來愛護地球?【考題精練】一、用should或shouldn't填空。1.You____________keepyourroomcleanandtidy.2.We____________usetoomanyplasticbottles.3.It’slate.I____________gohomenow.二、單項選擇。()1.—Whatdoesitmean?—Itmeansyou________walkonthegrass.A.shouldn’tB.shouldC.could()2.Weshould________trees.A.toplantB.plantC.planting三、按要求完成句子。1.Weshouldnotwastewater.(改為同義句)Weshould_________water.2.Weshouldsaveenergybecausethereisnotmuchenergy.(對畫線部分提問)__________________wesaveenergy?3.Youshouldlittertherubbishandcutdowntrees.(改為否定句)You_________littertherubbish__________cutdowntrees.四、閱讀理解。Nowadaysmanypeoplelivealow-carbon(低碳的)life.MyauntAliceisoneofthem.Sheisalawyer(律師).Shehasanicecar.Butsheoftengoestoworkbysubway.Whensheisatwork,shealwaysprints(打印)onbothsidesofthepaper.It'sagoodwaytosavepaper,andtosavetrees.Herhomeisnotfarfromheroffice.Sheoftengoeshomeonfootafterwork.ShealwaysrememberstoturnofftheTVwhensheisn'twatchingit.Whensheisbrushingherteeth,sheneverwasteswater.Ishouldlearnfrommyaunttolivealow-carbonlife.閱讀短文，選擇正確的答案。()1.Aliceisa.A.lawyer B.worker C.driver()2.Aliceoftengoeshome.A.bysubway B.bycar C.onfoot()3.Tosavetrees,weshould.A.savepaper B.cutdowntoomanytrees C.gotoworkbytaxi()4.WhenAliceisbrushingherteeth,she.A.turnsofftheTV B.turnsoffthetap C.wasteswater()5.Accordingtothepassage,weshouldlivealife.A.healthy B.low-carbon C.happy參考答案不行數名詞答案：一、1.comes2.isn't3.much;makes4.milk5.is;it6.energycomes7.bottles;orangejuice8.rice;chicken9.is;are10.keeps11.women
