______作主語作表語作主語作主語作表語[歸納用法]一、動詞不定式作主語1．動詞不定式作主語時，謂語動詞常常用單數(shù)。例如：

Todomorningexercisesisusefulforourhealth．做早操有利于我們的健康。

Tosweepthefloorismydutyeveryday．每天掃地是我的責(zé)任。2．如果動詞不定式太長，常常用it作形式主語，而將真正的主語——動詞不定式后置。例如：

Ittookmehalfanhourtowalkthere．我走到那兒花了半小時的時間。It'simportantforustolearnEnglishwell．對我們來說，學(xué)好英語是重要的。[名師點津]

it作形式主語時常用動詞不定式作真正的主語。常見的句型有：(1)Itis＋adj．＋for/ofsb．todosth．這種句型中不定式的邏輯主語一般用for短語來表示，即forsb．todosth．。注意：當(dāng)表語形容詞表示不定式的邏輯主語的性質(zhì)或特征時，則不用for，而用of。It'simportantforustokeepthewaterclean．保持水質(zhì)潔凈對我們來說是很重要的。It'sverykindofyoutosayso．你這樣說真是太好了。(2)Itis＋n．＋todosth．Itmustbegreatfuntoflytothemooninaspaceship．乘宇宙飛船飛往月球一定很有趣。(3)Ittakes(took/willtake)sb．sometime/moneytodosth．Ittookmemorethananhourtodomyhomeworkyesterdayevening．昨天晚上我做作業(yè)用了一個多小時。3．動詞不定式與疑問詞which，what，when，where，how等連用，也可作主語。Howtousethecomputerisaquestion．如何使用計算機(jī)是個問題。Wheretogohasnotbeendecided．去哪兒還沒有定下來。4．動詞不定式的被動形式作主語。Tobeadmittedbyakeyuniversityisdifficultforhim．對他來說，被一所重點大學(xué)錄取是困難的。[即時訓(xùn)練1]單句語法填空/補(bǔ)全句子①______(talk)withherisagreatpleasure．②It'sdangerous___youtowalkthroughtheforestalone．③It'scareless__youtogivemethewrongnumber．④____________(offer)sympathybyarobotisridiculous．⑤________________________(如何操作這臺機(jī)器)isaquestion．⑥Ittookhimonehour_______________(修理他的自行車)．TotalkforofTobeofferedHowtooperatethemachinetorepairhisbike二、動詞不定式作表語1．表示目的。Thenextstepistomakesurethatyouknowexactlywhatisrequired．下一步你要弄清楚真正需要的是什么。2．表示事態(tài)發(fā)展的結(jié)果、預(yù)期的結(jié)果、不幸的命運(yùn)或預(yù)言。Hewastoperishinashipwreckandtoleavehiswifeandtwochildren．后來他在一次船只失事中死了，留下了妻子和兩個孩子。3．用于第一人稱疑問句，表示征求意見。WhatamItosayiftheyaskmethequestion?要是他們問我這個問題，我該怎么回答呢？WhatamItodoifIhavenomoney?如果沒有錢，我該怎么辦呢？4．表示“同意、安排、命令、決定、勸告、意愿、禁止”等。Theyaretomarrynextweek．他們將在下周結(jié)婚。(安排)Childrenarenottosmoke．兒童不準(zhǔn)吸煙。(禁止)5．用主動形式表示被動意義。Sheistoblame．她應(yīng)該受到責(zé)備。Agreatdealisyettodo．還有許多事要做。[名師點津]

(1)如果be動詞前有實義動詞do或do的其他形式(does，did)，作表語的不定式可以省略to。Whatwecandonowiswaitherepatiently．我們現(xiàn)在能做的就是在這兒耐心等待。(2)“疑問詞＋不定式”也可以作表語。Thequestionishowtofinishthework．問題是如何完成這項工作。(3)不定式的被動形式也可以作表語。Youaretoberewarded．你應(yīng)該受到獎勵。[即時訓(xùn)練2]單句語法填空/補(bǔ)全句子①Thefestivalis________(hold)nextFriday．②Whois_______(blame)forstartingthefire?③Thedutyofadoctoris_______(treat)thesick，tocuretheinjured，andtosavelives．④Hiswishis___________(買一輛車)inthenearfuture．⑤Intheevening，theonlythinghecoulddowas__________________(安靜地讀書)．tobeheldtoblametotreattobuyacar(to)readabookquietly短文語法填空Thesedays，1．_____toeatisimportant．Somepeople'sopinionis2．______(have)somethingthattheythinktastesgood．However，3．____(do)so，tosomeextent，is4．_____(eat)anunbalanceddiet，whichoftenresultsinshort-termorlong-termhealthissues．Ifyouraimis5．______(keep)healthy，thenyouneedabalanceddiet．Needlesstosay，itisnotalwayseasy6．______(plan)suchadiet，butthegoodthingisthatyoucaneasilygetalotofadvicetoday．whattohavetodotoeattokeeptoplanWhatyoucoulddofirstis7．____________(look)ata“foodpyramid”—achartwhosefunctionis8．______(show)youhowtoeathealthily．Besides，itiseasy9．_______(make)healthyfoodathomeandtry10．_______(avoid)eatingtakeoutorfastfood．Itisimportantforyoutoeathealthyfood．Youwillfeelbetter，havemoreenergy，andhavefewerhealthproblemsinlaterlife．(to)looktoshowtomaketoavoid①heatup加熱②looseadj．不受約束的；未固定牢的；零散的；寬松的；疏松的letsth．loose釋放；放任③becoveredwith覆蓋④chilli
