初中英语动词不定式用法小结

动词不定式是动词的一种非谓语形式,又叫非谓语动词,它没有人称和数的变化,在句子中不能做谓语;它由“to+动词原形”构成,这里的to是动词不定式符号,本身没有词义,其否定形式常在to前加not;由于它仍保持动词的特点,可以有自己的宾语和状语,还可以带疑问词和由for引出其逻辑主语等形成动词不定式短语;不定式或不定式短语具有名词、形容词和副词的特征,在句子中可作主语、表语、宾语、宾语补足语、定语和状语等句子成分。为使同学们更好地掌握其用法,现总结如下:

一、动词不定式作主语

动词不定式作主语时,为避免句子的头重脚轻,常用it作为形式主语,而真正的主语动词不定式后置。如要说明动作的执行者,可在不定式前加for引导的短语;但如果表语是ni ce, ki nd, clever 等描述动作执行者的性格、品质的形容词时,则应在不定式前加of引导的短语。常用句型:It +be+adj./n.+(for/of sb.) to do sth./It takes sb. some ti me to do sth.

二、动词不定式作宾语

一些动词,如want, decide, hope, ask, agree, choose, learn, plan, need, teach, prepare,等,常接动词不定式作宾语。当动词不定式作宾语时,如果后接宾语补足语,常用i t作形式宾语,而把真正的宾语放在宾语补足语之后。应注意有些动词后面可接不定式作宾语,也可接动名词作宾语,但所表达的意义不同。常见的有:(1)stop to do sth.停止正在做的事,去做另一件事;stop doing sth. .停止正在做的事(2)go on to do sth. 做完一件事后,继续做另一件事;go on doi ng sth.继续做同一件事(3)remember/forget to do sth.记住/忘记去做某事;remember/forget doi ng sth. 记得/忘记做过某事

三、动词不定式作定语

动词不定式作后置定语时,与被修饰的名词逻辑上有动宾关系。如果动词不定式是不及物动词时,则要带上与之搭配的介词,构成及物动词短语。动词不定式作后置定语常用于“have/has +某事+to do”或“enough+名词+to do”“It’s ti me to do sth.”等结构中。

四、动词不定式作宾语补足语

有些动词,如tell, ask, want, invite, teach, like, call等可接带to的动词不定式作宾语补足语,构成tell/ask/want /call/i nvi te sb. to do sth.结构。应注意动词不定式作使役动词和感官动词的宾语补足语时应省去to,在被动语态中应加上to。这些动词可归纳为“一感(feel),二听(li sten to, hear),三让(let, make, have,,四看(l ook at, see, watch, noti ce),半帮助(hel p)(即在动词help后面作宾语补足语时,to可有可无)”。另有口诀帮助记忆:“感使动词真奇怪,to在句中像妖怪,主动句中to离开,被动句中to回来。”(let不用于被动语态)

五、动词不定式作状语

动词不定式作状语主要用来修饰动词,表示目的,结果或原因。为了强调目的,有时可以把动词不定式放在句首,或在不定式前加in order或so as。常用结构有too + adj./adv. + to dosth.等。

六、固定句式中动词不定式的用法

在固定句式中对不定式的考察常见的有:had better (not) do sth./W oul d you li ke to do sth.?/Why not do sth.?/Would you please (not) do sth.?等。

It's our duty to keep our environment clean and tidy.(Lesson 10). 点击规律:动词不定式在句中作主语时,常放在It is +adj.(形容词)+to do sth.或 It is +n.(名词)+to do sth.句型中,it仅作形式主语。 2.作宾语 a.以下动词只能to do 作宾语。 attempt企图 enable能够 neglect忽视 afford负担得起 demand要求 long渴望 arrange 安排 mean意欲,打算 begin开始 expect期望 appear似乎,显得 determine决定 manage设法 cease停止 hate憎恨,厌恶 pretend假装 ask问 need需要 agree同意 desire愿望 love爱 swear宣誓 volunteer志愿 wish希望 bear承受 endeavor努力 offer提供 beg请求 fail不能 plan计划 bother扰乱;烦恼 forget忘记 prefer喜欢,宁愿 care关心,喜欢 happen碰巧 prepare准备 decide决定 learn学习 regret抱歉,遗憾 choose选择 hesitate犹豫 profess表明 claim要求 hope希望 promise承诺,允许 start 开始 undertake承接 want想要 intend想要 refuse拒绝 decide决定 learn学习 contrive设法,图谋 incline有…倾向 propose提议 seek找,寻觅 try试图 b.love,like ,begin,start,hate ,prefer等词后面可以接不定式。 点击规律:上述动词后面除接不定式外,还可以接动名词,意思无很大区别。 提示板:like doing指经常性动作,而like to do指一次性的动作。如: I like swimming,but I don't like to swim now.我喜欢游泳,但我现在不想游。 c.stop,forget,remember,go on ,try等词或短语后面可以接不定式。 点击规律:上述动词后面接不定式和接动名词意思大不相同。 1)stop to do sth.:停止一件事,去做另一件事。 stop doing sth.:停止正在做的事。 例句:When the teacher came in,the students stopped talking;when he came out,the students stopped to talk. 当老师走进来时,学生们停止说话;当老师走出去时,学生们又开始说话。 2)思考:forget,remember,go on,try等词或短语后面接不定式和动名词用法有何区别d.在find/feel+it+adj.+to do sth.句型中,it是形式宾语,真正的宾语是后面的动词不定式。如: The man downstairs found it difficult to get to sleep.

英语动词不定式的完成式用法小结

英语动词不定式完成式在使用语境中的学习与考查 江苏省沛县湖西中学鹿俊先221611 综观近年的英语高考试题,我们可以看到题目的设置往往强调语言知识在特定语境中的使用,把语言知识放在了语用层面上,即考察实际应用知识的能力。 英语动词不定式的完成式,即(to) have +动词的过去分词形式,是中学英语学习中的重点及难点知识之一,也是高考试题中频繁出现的形式。对于这一形式考查的题目设置通常围绕三类语境,即陈述已经发生过了的事实,推测可能已经发生过了的事实,表达与过去实际情况相反的事实。下面分别加以叙述,以便从语用角度掌握这一语言知识。 1.陈述已经发生过了的事实。 1.1.置于表示情感反应的动词、形容词、分词之后,作为引起该反应的刺激,表示情感反应之前完成的动作。例如: I'm sorry to have given you so much trouble. (=I'm sorry that I gave / have given you so much trouble.) It is good to have finished work for the day. (=I am pleased because I have finished.) She said she was sorry to have missed you. (=She said she was sorry that he had missed you.) There was a smile on the boy's face, which seemed to show that he was happy to have given his life to his country. (=…he was happy that he had given his life to his country.) 1.2.置于be said, be considered, be believed, seem, appear, happen, turn out,等之后表示这些动作之前完成的动作。例如: I don't know whether you happen to have heard, but I am going to study in the U.S.A. this September. Charles Babbage is generally considered to have invented the first computer. (=It is generally considered that Charles Babbage invented the first computer.) He is said to have studied abroad, but I don't know which country he studied in. (= It is said that he studied abroad, b ut….) I appear to have made a small mistake. (=It appears that I made / have made a small mistake.) He seems to have missed the train. (=It seems that he missed the train.) 1.3.置于should之后,表达说话人对已发生了的事实的情感的反应,如惊奇、遗憾、喜悦、不安、失望,等,should相当于汉语中的“竟然”,“居然”。例如:They were surprised (that) a child should have worked out the problem while they themselves couldn't. It is strange that she should have married such an old man. 2.推测可能已经发生过了的事实。 2.1.置于must, will, would, can't, couldn't 之后,表示很有把握的推论。例如: The city must have been prosperous, for it enjoyed a high level of civilization. An ambulance is waiting in the street. Somebody must have been hurt or killed. --I met her soon after the war.

1. 不定式的用法------1.1 不定式作主语 不定式作主语,往往用it作形式主语,真正的主语不定式放至句子的后面。 例如:It's so nice to hear your voice. 听到你的声音真高兴。 It's necessary for you to lock the car when you do not use it. 不用车的时候,锁车是有必要的。 It's very kind of you to help us. 他帮助我们,他真好。 It seemed selfish of him not to give them anything. 他不给他们任何东西,这显得太自私了。 但是,用不定式作主语的句子中还有一个不定式作表语时,不能用It is… to…的句型。另外,这样的句子,不能用动名词作表语。例如: (对)To teach is to learn. (错)It is to learn to teach. (错)To teach is learning. (错)Teaching is to learn. 典型例题 The chair looks rather hard, but in fact it is very comfortable to ___. A. sit B. sit on C. be seat D. be sat on 答案:B. 如果不定式为不及物动词,其后应有必要的介词。当动词与介词连用时,常位于"形容词+动词不定式"结构的末尾。 1.1.1 不定式做主语It's for sb/It's of sb to do sth 这样的句子中,由于表语形容词性质的不同,导致了不定式逻辑主语标志用for或of 的区别。 1)for sb.句型中的形容词一般为表示事物的特征特点,表示客观形式的形容词,如easy, hard, difficult, interesting, impossible等:例如: It's very hard for him to study two languages. 对他来说学两门外语是很难的。
