本单元重点讲动词不定式作目的状语和宾语补足语。
The infinitive t d
1）不定式的形式 t＋动词原形：称为带t的不定式； 有时t可以省略：称为不带t的不定式。 其否定形式为“nt＋t＋动词原形”。 e.g. He wanted t run.（带t的不定式）他想跑。 Let him run.（不带t的不定式）让他跑。 Mm warned me nt t play ftball in the street. 妈妈警告我不要在街上踢足球注意: 这里的t只是个语法符号，没有词义。不定式在句中 不能独立作谓语，也没有人称和数的变化。
2）动词不定式的用法 动词不定式具有名词、形容词和副词的功能，在句中可以作主语、表语、宾语、宾语补足语（宾补）、定语、状语等。 e.g. T learn Chinese well is useful fr us.（作________） (= It’s useful fr us t learn Chinese well.) 学好语文对我们有用。(动词不定式作主语时,常用it作形式主语,将真正的主语不定式置于句尾。) My task tday is t help yu with yur hmewrk.（作________） 我今天的工作是帮助你完成作业。 I decide t visit Changsha.（作_________）我决定去长沙旅游。 I heard him sing every mrning.（作________）我每天听到他唱歌。 Wuld yu like t have smething t dink？（作定语）你想喝点什么吗？ I get up early t catch the carly bus.（作___________） 我每天早晨早起是为了赶早班公共汽车。
考向1 动词不定式作目的状语
①动词不定式（短语）作目的状语时，通常意为“为了······”，用于说明 动作的目的或意图。②动词不定式（短语）作目的状语时可放在句首，一般用逗号与后面 的内容隔开，也可放在句尾。e.g. T get there n time, they started early. 为了准时赶到那儿,他们很早就出发了。 = They started early t get there n time.特别提醒：表示目的也可用in rder t和s as t，但s as t 通常 不位于句首。 e.g. He reads every day in rder t/s as t imprve writing skills. 为了提高写作技能，他每天阅读。练习： （无锡中考）The children did a lt f research in the lab __________ (finish) the science prject.
拓展：动词不定式作状语
动词不定式作状语 动词不定式（短语）作状语往往表示目的、结果或原因等。 ① 作目的状语 作目的状语的动词不定式可置于句首，也可置于句末， 可与 in rder t d 互换。注意：常用于t d、in rder t d / s as t d等结构中, 表示“为了做”。 e.g. He came here t see me. 他来这儿是为了见我。 ② 作结果状语 常用于 d sth.(太而不能做某事)、 t d sth.(足够做某事)、 t d sth.(如此以至于做某事)等结构中。 e.g. He is t yung _________(g) t schl. = He is nt ld enugh t g t schl. 他太小了，不能去读书。
动词不定式作状语 动词不定式（短语）作状语往往表示目的、结果或原因等。③ 作原因状语 不定式作原因状语时往往跟在表示高兴、愉快、生气、荣耀、遗憾等情感形容词之后，说明产生这种情感的原因。常用于be glad/sad/happy/srry/pleased/surprised/disappinted/... t d sth.结构中。 e.g. I'm pleased t be invited t talk here. 我很高兴被邀请来这里谈话。练习：我很开心带领你们参观公园。() I’m very glad ___________________ the park.
t shw yu arund
考向2 动词不定式作宾语补足语
用于补充说明宾语的动作或状态，通常用于某些动词之后，构成“动词＋宾语＋不定式”结构。
①用于“命令、要求、允许”类动词后，如ask、tell、rder、require、 allw、permit。 e.g. Sam asked me t help him. 萨姆让我帮助他。 The teacher always tells us nt t swim in the river. 老师总是叮嘱我们不要在河里游泳。
②用于“希望、期望”类动词后，如want、wish、expect、wuld like。 e.g. Parents want their children t grw up healthily. 父母希望孩子健康成长。
③用于使役动词（如make、have、let等）和感官动词（如see、watch、 ntice、hear、listen t、feel等）后时，动词不定式通常省略t。 e.g. Did yu ntice her leave the huse？你注意到她离开屋子了吗？ I saw her get int the car. 我看见她上了车。 His parents let him sweep the flr. 他父母让他扫地
口诀： 一感 (feel) 二听 (hear, listen t) 三使 (have, make, let) 四看 (see, watch, ntice, bserve) 半帮助 (help) → 动词不定式(短语)在help后作宾语补足语时， 可带t也可不带t。
拓展：作宾语补足语 有的动词后接带t的不定式作宾语补足语；有的动词后接不带t的不定式作宾语补足语（如：感官动词和使役动词后）。注意：这些感使动词在“主动变被动”时，t要补回来，let除外。 e.g. The bss made the wrkers wrk lng hurs. = The wrkers were made t wrk lng hurs by the bss. 老板让员工长时间工作。练习：I have a lvely gldfish and I ften watch it ________ happily in the tank. A. swims B. swimming C. t swim D. swim
④用于其他动词后，如teach、warn、invite、encurage等。
练习：（云南中考改编） Our headmaster will invite a scientist __________ (give) us a speech n space technlgy.
解析：句意：我们的校长将邀请一位科学家为我们做一次关于航天技术的演讲。invite sb. t d sth.“邀请某人做某事”，此处用动词不定式作宾语补足语。故填t give。
拓展：疑问词+动词不定式
“疑问词+动词不定式（短语）” 动词不定式（短语）可以和疑问代词wh、whm、what、which或疑问副词when、hw、where及连词whether连用构成“疑问词/连词+动词不定式（短语）”结构，该结构在句中充当主语、 宾语、表语等成分。 e.g. What t d is an imprtant thing. (作主语) 要做什么是一件重要的事情。 I can't decide what t d. (作宾语) 我决定不了做什么。 The questin is when t start. (作表语) 问题是什么时候开始。练习：When I feel dwn, my best friend always knws hw ______ me up.
