Asteenagersgrowup,theybecomemoreindependent…

此句是复合句，asteenagersgrowup是时间状语从句，as表示“随着”。

egAstimewenton,hegotusedtolivingwithhishostfamilyandfeltathome.随着时间的推移，他习惯了跟寄宿家庭生活在一起，不感到拘束了。as还可以引导其它从句，如：Itwasaclosefinish,astheyhadpredicted.

正如他们所预料的，比赛结果难分上下。Theracewascalledoffasahurricanestruck.

由于飓风袭击，比赛被取消了。Happyastheywere,therewassomethingmissing.

尽管他们很快乐，但总缺少点什么。Mysleepleftmeasthelightleftthenight.

睡眠弃我而去如同光明离开黑夜。LanguagePoints2.Thesebadhabits,ifleftunchecked,couldleadtomoreseriousoneswhentheybecomeadults.

此句为复合句。ifleftunchecked是条件状语从句的省略，if后面省略了theyare，完整的形式为ifthesebadhabitsareleftunchecked。状语从句的省略1)可以省略成分的状语从句：时间、条件、让步、方式。2)状语从句省略成分的条件：从句主语与主句主语一致，或从句主语是it;从句谓语含有be，包括系动词be、进行时态的be或被动语态的be。3)常见的连词：when,while,once,before,whenever,if,unless,though,although,as,asif。4)状语从句省略成分后常见的类型：连词+现在分词/过去分词/介词短语/形容词。egIfinvolvedinthecase,youwillbepunished.Ifneccessay,youcanchoosemetomakethepresentation.2)

在if引导的条件状语从句中，当状语从句的主语是it，且谓语动词是be时，it和be可以省略。If(itis)possible,youshouldtrytovisitWashington,D.C.Wouldyoudropinatmyhousethisafternoonif(itis)convenienttoyou?3)if省略结构的固定结构：Itsoundslikesomethingiswrongwiththecar’sengine.Ifso,we’dbettertakeittothegarageimmediately.Pleasetellheryourfeelingsaboutthethingsaroundifpossible.Pleaseletmeknowhowmanyarecoming,ifany.Themostseverepunishmentsareseldom,ifever,applied.I’dsayhewasmorelikehisfather,ifanything.1)在if引导的条件状语从句中，如果从句的主语和主句的主语一致，同时从句谓语动词含有be动词，则可省略从句的主语和be动词。If(youare)travelingnorth,youmustchangeatMoscow.Practice1.Ifnot____________(treat)withtherespecthefeelsduetohim,Jackgetsveryill-temperedandgrumblesallthetime.2.Themedicinewillworkbestif______(take)accordingtotheinstructions.3.Youmustfindyourselfupsetbytrafficjamsif_____(live)inthecentreofthecity,especiallyduringtherushhour.4.Ifthestepsyoutakeareworking,keepitup.______(不然),takeanotherlookatothermethodsyoucouldtry.takenlivingIfnotbeingtreated3.Topreventharmfulhabitslikethesefromdominatingateenager’slifeisessential.

▲此句为“主系表”结构的简单句，其中主语较长，是不定式短语Topreventharmfulhabitslikethesefromdominatingateenager’slife。Therearetwosentencesinthepassagewhichcontainsthesamestructure:infinitivephraseisusedasthesubject.Lookforthemandwritethemdown.▲Tochangebadhabitsisnevereasy,evenwithmanyattempts.▲Afterall,itisnoteasytobreakbadhabits.▲ItisagreathonortobeinvitedtoMary’sbirthdayparty.▲Itwasimpossibleforlosttimetobemadeup.有时为了保持句子平衡，经常将不定式短语放到句子后面，尤其当不定式形式为被动结构时。TheTrueStoryofAhQ
