2012届高考英语二轮复习精品课件第2模块 语法填空 专题2　说明文型语法填空

专题二说明文型语法填空,专题二说明文型语法填空,专题二专题导读,说明文是对事物的特征、本质、性能、状态，或事物的发生、发展、结果、用途、原理等进行介绍、解释、说明的一种文体。其语言特点有：1多用现在时态。因为说明文通常是对客观事物或事理的一种介绍与解释。2采用客观描述。说明文一般是对客观存在的说明与介绍，因此，语言的表述也应该尽可能地给人以客观可信的感觉。分析句子结构是答题过程中很关键的一步。做题时，首先确定句子的主谓宾成分，看看该句子缺不缺谓语动词，然后再考虑非谓语动词或者其他成分。此时，要借助上下文的暗示或明示，确定需要填入词语的词性、形式和功能等。,专题二典例导练,Theairwebreatheisfreelyavailable,withoutwhichwecouldnotsurvivemorethanafewminutes.Forthemostpart,airisavailabletoeveryone,andeveryone_1_(need)it.Somepeopleusetheairtosustainthemwhile_2_(seat)aroundandfeelsorryforthemselves._3_breatheintheairandusetheenergyitprovidestomake_4_magnificentlife.Opportunityis_5_thesameway;itiseverywhere.Itis_6_freelyavailablethatwetakeitforgranted.Yetopportunityaloneisnotenoughtocreatesuccess,itmust_7_(seize)andacteduponinordertohavevalue.Somanypeoplearesoanxiousto“getin”ona,专题二典例导练,“groundflooropportunity”，asiftheopportunitywilldoalltheworkthats_8_(possible)Justasyouneedairtobreathe,youneedopportunitytosucceed.Ittakesmorethanjustbreathinginthefreshairofopportunity,_9_.Youmustmakeuseofit.Thatsnotuptotheopportunity,thatsuptoyou.Itdoesntmatterwhat“floor”theopportunityison,but_10_mattersiswhatyoudowithit.1_2._3._4._5_6._7._8._9_10._,专题二典例导练,【解析】1needs考查主谓一致，由全文时态可知用一般现在时，everyone后用第三人称单数。2seated过去分词作伴随状语，相当于“whiletheyareseated”。3Others句型：some.others.4a表示“一种奇妙的生活”，是泛指，故用不定冠词a。5inintheway是固定搭配。,专题二典例导练,6so句型：so.that.7beseized依据上下文的理解，可知句意表示“有机遇必须抓住，你才能成功”。8impossible依据上下文和构词法，此处应为“不可能的”，故用“impossible”。9however/though插入语，意为“然而”。10what引导主语从句且在句中作主语，故用what。,专题二新题预测,(一)Twoseedslaysidebysideinthefertilespringsoil.Thefirstseedsaid,“Iwanttogrow!Iwanttosendmyrootsdeepintothesoil_1_me,andthrustmysprouts(芽)_2_theearthscrustaboveme.Iwanttoopenmytenderbuds(蓓蕾)likebannerstoannouncethe_3_(arrive)ofspring.Iwanttofeelthewarmthofthesunonmyfaceandtheblessingofthemorningdew(露水)onmypetals(花瓣)！”Andsoshegrew.Thesecondseedsaid,“Iamafraid.IfIsendmyrootsintothegroundbelow,IdontknowwhatI_4_(come)acrossinthedark.IfIpushmywaythrough,专题二新题预测,thehardsoilaboveme,Imaydamagemydelicatesprouts.WhatifIletmybudsopenandasnail(蜗牛)tries_5_(eat)them?And_6_Iweretoopenmyblossoms,_7_smallchildmaypullmefromtheground.No,itismuch_8_(good)formetowait_9_itissafe.”Andsoshewaited.Ayardhenscratchingaroundintheearlyspringgroundforfoodfoundthewaitingseedandimmediatelyate_10_.1_2._3._4._5_6._7._8._9_10._,专题二新题预测,【解析】两颗种子的故事，告诉我们惧怕冒险和成长，最终要被生活吞没。1beneath介词，意为“在之下”与下文的above相对。2through介词，意为“穿过”。3arrival在冠词后用名词。4willcome对未来的预测，句意为：我不知道在黑暗之中将会遇到什么。5toeat因try表示“试图做某事”，后接不定式。6ifif引导虚拟条件句。7a表示泛指的“某一个”小孩，故用不定冠词a。,专题二新题预测,8better隐性比较级，即“等”比“长”好得多。句中much也提示我们要用比较级，因为much常用来修饰比较级，表示“得多”。9until意为“直到”，引导时间状语从句。10itit指代前文中的thewaitingseed。,专题二新题预测,(二)Whatwouldyoudoifyoufailed?Manypeoplemaychoosetogiveup._1_,thesurestwaytosuccessistokeepyourdirectionandstick_2_yourgoal.Onyourwaytosuccess,you_3_keepyourdirection.Itisjustlikealamp,guidingyouindarknessand_4_(help)youovercomeobstaclesonyourway._5_,youwilleasilygetlostorhesitatetogoahead.Directionmeansobjectives.Youcangetnowhere_6_anobjectiveinlife.,专题二新题预测,Youcantrytowriteyourobjectiveonpaperandmakesomeplanstoachieve_7_.Onlyinthisway_8_youknowhowtoarrangeyourtimeandtospendyourtime_9_(proper)Andyoushouldalsohaveabelief_10_youaresuretosucceedaslongasyoukeepyourdirectionallthetime.1_2._3._4._5_6._7._8._9_10._,专题二新题预测,【解析】本文告诉我们，要想成功，最可靠的方法就是坚持你的方向和目标。1However与前句是转折关系，空格前后都有标点，用副词however。2tostickto意为“坚持”。3must由语境不难揣摸出作者的语气，句意为：在通往成功的路上，你必须坚持你的方向。4helping与guiding并列，一起补充说明alamp，故用现在分词。5Otherwise由本句与前句的逻辑关系可知，要填表示“否则”的otherwise。,专题二新题预测,6without句意：人生如果没有目标，你将一事无成。7itit指代yourobjective。8will/can句意：只有这样，你才会知道9properly修饰动词spend作状语用副词。10that引导同位语从句，从句中不缺句子成分，且意义完整，故填that。,专题二新题预测,(三)Ithappenedthatadoghadgotapieceofmeatandwascarrying_1_homeinhismouth.Now,_2_hiswayhomehehadtocrossaplanklying_3_arunningbrook._4_hecrossed,helooked_5_andsawhisownshadow_6_(reflect)inthewaterbeneath.Thinkingitwas_7_dogwithanotherpieceofmeat,hemadeuphismindtohavethatalso.Sohemadeasnapat_8_shadowinthewater,_9_asheopenedhismouththepieceofmeatfellout,_10_(drop)intothewaterandwasneverseenmore.Bewarelestyoulosethesubstancebygraspingattheshadow.,专题二新题预测,1_2._3._4._5_6._7._8._9_10._,专题二新题预测,【解析】这则狗和影子的故事，告诫我们：切莫因追逐幻影而丢失已有的东西。1it指代apieceofmeat，故用it。2on表示“在某人回家的路上”用ononeswayhome。3across表示“横过”河流或道路等细长的东西或操场等一个平面的东西，用介词across
