______作主语作表语作主语作主语作表语[归纳用法]一、动词不定式作主语1．动词不定式作主语时，谓语动词常常用单数。例如：

Todomorningexercisesisusefulforourhealth．做早操有利于我们的健康。

Tosweepthefloorismydutyeveryday．每天扫地是我的责任。2．如果动词不定式太长，常常用it作形式主语，而将真正的主语——动词不定式后置。例如：

Ittookmehalfanhourtowalkthere．我走到那儿花了半小时的时间。It'simportantforustolearnEnglishwell．对我们来说，学好英语是重要的。[名师点津]

it作形式主语时常用动词不定式作真正的主语。常见的句型有：(1)Itis＋adj．＋for/ofsb．todosth．这种句型中不定式的逻辑主语一般用for短语来表示，即forsb．todosth．。注意：当表语形容词表示不定式的逻辑主语的性质或特征时，则不用for，而用of。It'simportantforustokeepthewaterclean．保持水质洁净对我们来说是很重要的。It'sverykindofyoutosayso．你这样说真是太好了。(2)Itis＋n．＋todosth．Itmustbegreatfuntoflytothemooninaspaceship．乘宇宙飞船飞往月球一定很有趣。(3)Ittakes(took/willtake)sb．sometime/moneytodosth．Ittookmemorethananhourtodomyhomeworkyesterdayevening．昨天晚上我做作业用了一个多小时。3．动词不定式与疑问词which，what，when，where，how等连用，也可作主语。Howtousethecomputerisaquestion．如何使用计算机是个问题。Wheretogohasnotbeendecided．去哪儿还没有定下来。4．动词不定式的被动形式作主语。Tobeadmittedbyakeyuniversityisdifficultforhim．对他来说，被一所重点大学录取是困难的。[即时训练1]单句语法填空/补全句子①______(talk)withherisagreatpleasure．②It'sdangerous___youtowalkthroughtheforestalone．③It'scareless__youtogivemethewrongnumber．④____________(offer)sympathybyarobotisridiculous．⑤________________________(如何操作这台机器)isaquestion．⑥Ittookhimonehour_______________(修理他的自行车)．TotalkforofTobeofferedHowtooperatethemachinetorepairhisbike二、动词不定式作表语1．表示目的。Thenextstepistomakesurethatyouknowexactlywhatisrequired．下一步你要弄清楚真正需要的是什么。2．表示事态发展的结果、预期的结果、不幸的命运或预言。Hewastoperishinashipwreckandtoleavehiswifeandtwochildren．后来他在一次船只失事中死了，留下了妻子和两个孩子。3．用于第一人称疑问句，表示征求意见。WhatamItosayiftheyaskmethequestion?要是他们问我这个问题，我该怎么回答呢？WhatamItodoifIhavenomoney?如果没有钱，我该怎么办呢？4．表示“同意、安排、命令、决定、劝告、意愿、禁止”等。Theyaretomarrynextweek．他们将在下周结婚。(安排)Childrenarenottosmoke．儿童不准吸烟。(禁止)5．用主动形式表示被动意义。Sheistoblame．她应该受到责备。Agreatdealisyettodo．还有许多事要做。[名师点津]

(1)如果be动词前有实义动词do或do的其他形式(does，did)，作表语的不定式可以省略to。Whatwecandonowiswaitherepatiently．我们现在能做的就是在这儿耐心等待。(2)“疑问词＋不定式”也可以作表语。Thequestionishowtofinishthework．问题是如何完成这项工作。(3)不定式的被动形式也可以作表语。Youaretoberewarded．你应该受到奖励。[即时训练2]单句语法填空/补全句子①Thefestivalis________(hold)nextFriday．②Whois_______(blame)forstartingthefire?③Thedutyofadoctoris_______(treat)thesick，tocuretheinjured，andtosavelives．④Hiswishis___________(买一辆车)inthenearfuture．⑤Intheevening，theonlythinghecoulddowas__________________(安静地读书)．tobeheldtoblametotreattobuyacar(to)readabookquietly短文语法填空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加热②looseadj．不受约束的；未固定牢的；零散的；宽松的；疏松的letsth．loose释放；放任③becoveredwith覆盖④chilli
