解析onEarth在此意為“在地球上；在世界上；在人世間”，此處的Earth前無需加定冠詞the。onearth可用于疑問詞之后加強語氣，意為“究竟；到底”。

舉例ThisisthelongestriveronEarth.這是世界上最長的河流。WhatonEarthdoyoumean?你究竟是什么意思？

運用地球上有生命嗎？（漢譯英）_____________________________________________________________________2.Wemuststopdoingthesethings.（P31，L20）我們必須停止做這些事情。

解析must，情態(tài)動詞，意為“必須”，后跟動詞原形。用于一般疑問句時，其肯定回答用“Yes,youmust.”或“I’mafraidso.”；否定回答用“No,youneedn’t.”“No,youdon’thaveto.”stopdoingsth.意為“停止做某事”，指停止正在做的事情。

舉例Imustgohomenow.我現(xiàn)在必須回家。Whenwesawtheteacher,westoppedtalking.當我們看見老師時，我們停止了講話。

解析在這個句子結(jié)構(gòu)中，it是形式主語，真正的主語是動詞不定式短語toprotecttheEarthforourfuture。該句型為：Itis+adj.+forsb.+todosth.“對某人來說，做某事是……的”。

舉例ItisnecessaryforustolearnEnglishwell.對我來說，學好英語是有必要的。

運用Itiseasyforhim______(answer)thequestion.課堂精練Ⅰ.翻譯下列短語1.為……提供……______ 2.制造能源______3.把……倒入……______ 4.停止做某事______5.在陸地上______ 6.很多；大量______7.在地球上；在世界上______

Chinese—Chinese中國人c.詞尾發(fā)生變化child—children孩子ox—oxen公牛d.復(fù)合名詞單數(shù)變復(fù)數(shù)時，將中心詞改為復(fù)數(shù)。boystudent—boystudents男學生e.含man或woman的復(fù)合名詞，前后兩詞都要改為復(fù)數(shù)形式。mandoctor—mendoctors男醫(yī)生（二）不可數(shù)名詞不可數(shù)名詞一般是借助“數(shù)詞+量詞+of+不可數(shù)名詞”的結(jié)構(gòu)來表示一定的量。量詞可以是單數(shù)，也可以是復(fù)數(shù)，但of后的不可數(shù)名詞只能用原形。如：aglassofwater一杯水twokilosofmeat兩公斤肉B.Usingthereis/are…(therebe句型)therebe句型表示“某處存在某物或某人”。常見的therebe形式如下：（1）肯定式：Thereis/are…（2）否定式：Thereis/arenot…（3）疑問式：Is/Arethere…?縮寫形式：thereis=there’sthereare=there’rethereisnot=thereisn’ttherearenot=therearen’t注意事項：there是引導(dǎo)詞，在句中不充當任何成分，翻譯時也不必譯出。句子的主語是某人或某物，謂語動詞be要與主語（某人或某物）的數(shù)保持一致。當主語是兩個或兩個以上的名詞時，根據(jù)就近原則，謂語動詞要和它最靠近的那個主語在數(shù)上保持一致。如：Thereisatableandtwochairsintheroom.房間里有一張桌子和兩把椅子。Therearetwochairsandatableintheroom.房間里有兩把椅子和一張桌子。（1）肯定式如果句子的主語是單數(shù)的可數(shù)名詞，或是不可數(shù)名詞，be動詞用“is”；如果句子的主語是復(fù)數(shù)名詞，be動詞就用“are”。如：Thereisabasketballinthebox.盒子里有一個籃球Therearemanybirdsinthetree.樹上有許多鳥。（2）否定式therebe句型的否定式的構(gòu)成和含有be動詞的其它句型一樣，在be后加上not或no即可。注意not和no的不同：not是副詞，no為形容詞，“nota/an/any+名詞”相當于“no+名詞”。另外，當肯定句中有some時，要將其改為any。如：Thereisn’tabikebehindthetree.=Thereisnobikebehindthetree.樹后面沒有單車。Thereisn’tanywaterinthebottle.杯子里沒有水。（3）一般疑問式therebe句型的一般疑問句是把be動詞調(diào)整到句首，再在句尾加上問號即可。但同時要注意：當肯定句中有some時，要將其改為any（否定變化也一樣）。如：Arethereanyfishinthewater?水里魚嗎？課堂精練Ⅰ.用所給單詞的適當形式填空1.Therearefive______(pencilbox)onthedesk.2.Three______(German)arewalkingonthePeople’sSquare.3.Wewillhaveseveral______(exam)thisterm.4.Theseworkersaregoingtoworkabroadforthreeyears.Their______(wife)willhavetostayathomealone.5.Ourcitieshaveafew______(zoo).6.There______(be)somewaterinthebottle.7.There______(be)abutterflyandseveralbeesinthegarden.8.There______(be)sevendaysinaweek.Ⅱ.按要求改寫句子1.Therearetwelvemonthsinayear.（改為一般疑問句）____________twelvemonthsinayear?2.Hehastwoballsunderhisbed.（用therebe句型進行改寫）________________________underhisbed3.Thereissomemilkinthebottle.（改為否定句）__________________milkinthebottle4.Thereare56studentsintheclassroom.（對劃線部分提問）____________students____________intheclassroom?5.Therearen’tanyapplesonthetable.（改為肯定句）__________________applesonthetable.Ⅲ.閱讀填空請閱讀全文，并從下面方框里的六個句子中選擇五個還原到短文中，使短文的意思完整、連貫。A.Allplantsneedlightandwater.B.Whenalittlebitofrainfalls,theplantsholdthewater.C.Theywanttobringwatertothedeserts（沙漠）,sopeoplecanliveandgrowfood.D.PeoplearedoingbadthingstotheearthE.Scientistsmaynotbeabletochangethedesertintime.F.Thisisbecausesomegreenplantsaregrowingthere.Scientistsaretryingtomakethedesertintogoodlandagain.1.______Theyarelearningalotaboutthedeserts.Butmoreandmoreoftheearthisbecomingdesertallthetime.2.______Whyismoreandmorelandbecomingdeserts?Scientiststhinkthatpeoplemakedeserts.3.______SomeplacesontheEarthdon’tgetmuchrain.Buttheystilldon’tbecomedeserts.4.______Smallgreenplantsandgrassareveryimportanttodryplaces.Plantsdon’tletthehotsunmaketheearthdrier.5.______Plantsdon’tletthewindblowthedirtaway.Withoutplants,thelandwillbecomeadesertmuchmoreeasily.第4課時Listening&Speaking聽說課堂精講Ⅰ.模仿朗讀聽以下短文一遍，給你50秒鐘的時間準備，然后模仿朗讀。當聽到“開始錄音”的信號后，立即在50秒鐘內(nèi)朗讀短文，當聽到要求“停止錄音”的信號時，停止朗讀。HowtoprotectourEarthhasbecomeoneofthebiggestproblemsintheworld.OurEarthisjustlikeourmother.Weshoulddoeverythingwecantoprotecther.Weneedtopickuplitteraroundus.You’dbetterjoinaprogrammetoprotectourmother.Youmustn’tcutdowntoomanytrees.Wecanstopfactoriesfrompollutingtherivers.Wecandoourbesttokeeptheairclear!Ihopeeveryonecandothese.Ⅱ.聽選信息聽三段對話，每段播放兩遍。各段播放前你有10秒鐘的閱題時間。各段播放后有兩個問題。請根據(jù)所聽到的問題選擇正確的答案。聽第一段對話，回答第1~2兩個問題?，F(xiàn)在你有10秒鐘的閱題時間。（）1.WhatdidLilylearnabouttheEarth?A.Someseriousproblems.
