19/70四、句子精析与仿写1.Theylivedontheearthtensofmillionsofyearsago,longbeforehumanscameintobeing...千百万年前它们(恐龙)就在地球上生活，比人类出现要早得多……

句子分析：(1)longbefore相当于longago，意为“很久以前”，惯用于过去时或过去完成时句子中作时间状语，before后边能够跟从句。(2)beforelong相当于soon或alittlelater，意为“很快；很快以后”，常与未来时、过去时态连用，在句中作状语，不能够接从句。(3)Itis/wasnotlongbefore+从句“很快就”。(4)Itwillbelongbefore+从句“要过很久才……”。20/70仿写：

(1)早在我来这儿很久以前我就听说过他情况。______________________________________________(2)很快之后他就去加拿大继续深造了，三年后才回来。______________________________________________(1)IhadheardofhimlongbeforeIcamehere.(2)BeforelonghewenttoCanadatogoonwithhisfurthereducationandreturnedthreeyearslater.21/702.Norainforest,noanimals,nodrugs.

没有雨林，就没有动物，也就没有药品了。句子分析：no为形容词，其后普通接名词。仿写：

(1)无风不起浪（无火不冒烟）。Nofire,_____________.(2)没有竞争就没有进步。______________________________________________(3)不劳无获。______________________________________________(1)nosmoke(2)Nocompetition,noprogress.(3)Nopains,nogains.22/703.Othersthinktheearthgottoohotforthedinosaurstoliveonanymore.其它人认为地球变得太热，以至于恐龙生活不下去了。

句子分析：too…to…“太……而不能……”。当too后面形容词为happy,ready,willing,eager,anxious等表心理状态词时，to后面动词表必定。23/70仿写：

(1)车太贵了，他买不起。______________________________________________(2)改过不嫌晚。______________________________________________(3)我只是太想知道结果了。______________________________________________(1)Thecaristooexpensiveforhimtoafford.(2)It’snevertoolatetocorrectmistakes.(3)I’mtooeagertoknowtheresult.24/704.Sheturnedaroundandtherewasanantelopewithasadfacelookingather.她转过身来，一只羚羊一脸苦相地望着她。

句子分析：复合结构with+宾语+宾补，普通在句中作状语或定语。25/70仿写：

(1)

因为他母亲帮助，他工作进展得很顺利。______________________________________________(2)有向导带路，我们很轻易就找到了那个村庄。______________________________________________(1)Withhismotherhelpinghim,heisgettingonwellwithhiswork.(2)It’seasyforustofindthevillagewiththeguideleadingtheway.26/705.Theylearnedthisfromthewaytheboneswerejoinedtogether.

他们从骨头接合方式上得知此结论。句子分析：theway后接定语从句中，关系代词通惯用that,inwhich或省略。仿写：

(1)我不喜欢你嘲笑她方式。______________________________________________(2)你这么个做法，简直是疯了。______________________________________________(1)Idon’tliketheway(that)youlaughather.(2)Theway(that)youaredoingitiscrazy.27/70SectionII读写强化一、依据课文回答以下问题：

46/7010.A.pressure B.strength C.direction D.speed11.A.standing B.lying C.fixing D.shaking12.A.pickedup B.lookedat C.threwawayD.turnedto10.B由上文theGrannyTreewasbent及下文Almostallherrootscameoutoftheground可知，GrannyTree变成这么都是因为风“力量”(strength)。11.A这里指人们想尽一切方法让GrannyTree再次“站”(stand)起来。12.B该句意为：GrannyTree看着她树枝和枯萎叶子。lookat和后面see相对应。47/7013.A.lasted B.left C.grew D.died14.A.hide B.talk C.play D.memory15.A.records B.books C.history D.memory13.D由下文可知，GrannyTree死了。14.C由上文可推断，此处说是在树枝丛中玩得很开心，故选play。15.DGrannyTree因为受环境污染所造成大风摧残已经死了，不过它却永远活在孩子们记忆中。inone’smemory“在某人记忆中”。48/70Ifyougoouttothefieldsatnightinspringorsummer,youcanhearfrogssinging__1__(joy)hereandthere.Itseemsasiftheywereperformingafieldsymphony.Thefrogisagoodandusefulcreaturethatbenefitshumanbeings.Theycancatchfast-movinginsects.Eachfrogeatsalargenumberofpeststhatareharmful__2__crops.Thislittlecreatureisregarded__3__“thenaturalenemyofpests”.四、语法填空字数：190完成时间：8分钟难度：★★★49/70__4__nowfrogsaregettingfewerandfewer.Thisisbecausetheyarekilledandputonthetableasadeliciousdishbytheirchiefenemy,humanbeings.Itis__5__shamelessandcruelact,isn’tit？__6__causeresponsiblefortherapidreductionoffrogsisthatfarmersuseinsecticides(杀虫剂)tokillpestsandfrogsgetkilledasaresultofdrinkingpoisonedwater__7__eatingpoison-killedinsects.Somethingmustbedonewithoutdelay__8__(save)frogs.Ifwedon’tpunishthose__9__sellandkillfrogstomakemoney,thenonedayallofus__10__(punish)bynatureforfailingtokeepthebalanceofnature.50/701.joyfully副词修饰动词。

2.to

beharmfulto“对……有害”，固定搭配。

3.as

beregardedas“被认为是……”。

4.But与上文是转折关系，且后面没有逗号，故用But。

5.a依据语意“这是一个不知羞耻残忍行为”，可知此处应用不定冠词。6.Another上文讲到“吃”青蛙是它数量降低一个原因，这里是“另一个”原因。7.or

(另一个原因是)青蛙喝了有毒水，或者吃了被毒死昆虫。二者是选择关系。8.tosave为了保护青蛙，要刻不容缓地采取行动。不定式表目标。9.who定语从句，因为先行词是those，指人，故用who引导。10.willbepunished依据语境此处用普通未来时被动语态。51/70五、阅读了解词数：300提议用时：8分钟难度：★★解题技巧点拨第3题Whyisairpollutionmuchgraverinthecitythaninthecountry?细节理解题细节了解题就是我们常见wh-题，它们大多是依据文章中详细信息如事实、例证、原因、过程、叙述等进行提问。有些问题能够在文章中直接找到答案，有些则要我们在了解基础上将相关内容系统化后才能找到，比如计算、排序、是非判断、图形比较等。52/70方

法对

策做这类题方法:普通是先用寻读法找出与问题相关词语或句子，再对相关部分进行细读，找出正确答案。本篇文章第一段后半部分说明，空气污染主要原因是汽车废气和用来发电煤和油燃烧。而汽车和电力在城市里比在郊区用得多。53/70真
