1、学习必备 欢迎下载 动词不定式三注意 动词不定式是动词的非谓语形式之一，常由“to+动词原形”构成，可在句中作主语，表语，宾语，宾语补足语，状语等。今天，咱们主要谈谈关于它的三个要多加注意的方面。1.作宾语的动词不定式何时省略 to 我们知道，像ask,want,invite,wish,expect,warn 等动词后常接带to 的动词不定式作宾语补足语。那什么时候把 to 省略呢？常见的有“一感二听三让四看半帮助”几种情况。即feel sb do sth;listen/hear sb do;make/let/have sb do sth;look at/see/watch/notice sb

2、 do sth;help sb(to)do sth。如：I often hear Molly sing songs in her room.我经常听见莫利在她的房间里唱歌。Dont make him stand outside.别让他在外边站着了。【知识拓展】若表示“看到/听到/感觉到某人正在做某事”，则用 see/hear/feel sb doing sth.如：I can hear someone singing at the door.我能听见有人正在问口唱歌。在被动语态中，这些不定式中被省略的 to 要还原。如：He was made to do more work.他被要求做更多的工

3、作。She was seen to play basketball.他被看见在打篮球。2.疑问词+不定式 不定式可以和疑问词 what,how,when,where 等连用，共同作句子的宾语或表语等，但此时不定式一定要放在疑问词的后面。学习必备 欢迎下载 如：Can you show me how to turn off the computer?你能让我看看如何关电脑吗？(how to do sth 作宾语)Where to spend the weekend hasnt been decided yet.去哪里度过周末还没有被决定出来呢。(where to do sth 作主语)3.不定式

4、和 it 不定式可以作句子的主语和宾语，但有时候它们因太长而显得句子结构不够完美，故常用 it 来代替它作形式主语或形式宾语。常见的句型有以下两个：It be+adj+for sb to do sth.对某人来说做某事怎么样。（it 作形式主语）sb thinks/find it+adj+to do sth.某人认为（发现）做某事怎么样。（it 作形式宾语）如：It is very easy for me to answer that question.对我来说，回答那个问题是很容易的。Did you find it hard to solve the problem?你觉得解决那个问题很难吗

5、？练一练：用括号内所给单词的正确形式填空。1.Can you tell me how _ to the cinema?（go）2.It is very easy for him _ that problem.（solve）3.Listen!Can you hear someone _ at our door?（knock）4.He was made _ his name on the blackboard.（write）5.We often see him _ books on the playground.（read）6.I find it hard _ a new language.（le

10、 sb,to do 6.B.stop to do 停下去做另一件事。stop doing 停止做某事。7.A.make sb do 在被动语态中为 be made to do.8.B.need to be done与 need doing皆为“需要被做”之意。9.B.不定式结构作表语。10.A.不定式的否定式：advise sb not to do 被动语态 一、语态概述 英语的语态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。等动词后常接带的动词不定式作宾语补足语那什么时候把省略呢常见的有人正在问口唱歌在被动语态中这些不定式中被省略的要还原如他被要载如你能让我看看如何

11、关电脑吗作宾语去哪里度过周末还没有被决定出学习必备 欢迎下载 主动语态表示主语是动作的执行者。巧记为：主动、主动、主去动。如：Many people speak English.谓语：speak 的动作是由主语 many people 来执行的。被动语态表示主语是动作的承受者，即行为动作的对象。巧记为：被动、被动、主被动。所谓“被动语态”，相当于中文中常说的“被”、“由”的句式，如：“他的自行车被偷了。”，“这座楼房是由他们建造的。”再如：English is spoken by many people.主语 English 是动词 speak 的承受者。判断：看下面的两个例句，你来判断哪个是

12、主动哪个是被动？He opened the door.他开了门。（_）The door was opened.门被开了。（_）说明：好了，现在我们对被动语态的句子形式有了一个形象的认识，但英语句子是千变万化的，这时就需要你有“火眼金睛”了。下面我们来具体了解一下被动语态的构成。二、被动语态的构成 被动特点强调宾（语），用 be 加上过去分（词）。行为对象作主语，逻辑主语by 来引。1.English is _（speak）in Canada.2.The blouse is _（make）of silk.3.English is _（speak）by many people.谁做的动作不知道，说

13、出谁做的没必要。动作承受者需强调，用被动语态莫忘了。1.Some stamps were _（steal）last week.2.The PRC was _（found）on October 1,1949.3.Football is _（play）in most middle schools.被动语态须留意，P.P 前面助动 be.be+P.P 等动词后常接带的动词不定式作宾语补足语那什么时候把省略呢常见的有人正在问口唱歌在被动语态中这些不定式中被省略的要还原如他被要载如你能让我看看如何关电脑吗作宾语去哪里度过周末还没有被决定出学习必备 欢迎下载 am（is,are）现在时，am（is,are

14、）+P.P was 和 were 表过去。was（were）+P.P 完成 have（has）been。have（has）been+P.P 将来，情态，be 原形。will（can,may,must）be+P.P 进行时态两个 be，前表时态后加 ing。am（is,are）+being+P.P 被动语态由“助动词 be及物动词的过去分词”构成。人称、数和时态的变化是通过 be 的变化表现出来的。说明：别看英语中一会儿主动被动一会儿现在时一会儿过去时啥的，好像看得咱们眼花缭乱啦。其实呢，这么一堆东西归纳起来，就两点：时态和语态。歌诀：被动语态 be 字变，过去分词跟后面。说明：那么，什么时候用

15、被动语态呢？简单的说，凡是汉语中带“被”的句子，都能转换成英语的被动语态。几种常用时态的被动语态 1.一般现在时：am/is/are+过去分词 肯定句：Bikes are _（sell）in that shop.否定句：Bikes are not sold in that shop.疑问句：Are bikes sold in that shop?Yes,they are./No,they arent.2.一般过去时：was/were+过去分词 肯定句：China was _（liberate）in 1949.否定句：China was not liberated in 1949.疑问句：Was

16、 China liberated in 1949?Yes,it was./No,it wasnt.3.一般将来时：shall/will/be going to+be+过去分词 等动词后常接带的动词不定式作宾语补足语那什么时候把省略呢常见的有人正在问口唱歌在被动语态中这些不定式中被省略的要还原如他被要载如你能让我看看如何关电脑吗作宾语去哪里度过周末还没有被决定出学习必备 欢迎下载 肯定句：An English class will be _（give）by Jack tomorrow.否定句：An English class will not be given by Jack tomorrow.

17、疑问句：Will an English class be given by Jack tomorrow?Yes,it will./No.it wont.4.现在进行时：am/is/are+being+过去分词 肯定句：A car is being _（drive）now.否定句：A car is not being driven now.疑问句：Is a car being driven now?Yes,it is./No,it isnt.5.现在完成时：have/has+been+过去分词 肯定句：A road has been _（build）by the government.否定句：A

18、 road hasnt been built by the government.疑问句：Has a road been built by the government?Yes,it has./No,it hasnt.6.情态动词：情态动词+be+P.P 1）This clock can be _（repair）here.2）The trees may be _（plant）at other times of the year.3）The composition must be _（hand）in after class.4）The young trees should be _（plant）

19、in spring.三、被动语态的用法（1）不知道或没有必要说明动作的执行者是谁。例如：Some new computers were _（steal）last night.一些新电脑在昨晚被盗了。（不知道电脑是谁偷的）This book was _（publish）in 1981.这本书出版于 1981 年。等动词后常接带的动词不定式作宾语补足语那什么时候把省略呢常见的有人正在问口唱歌在被动语态中这些不定式中被省略的要还原如他被要载如你能让我看看如何关电脑吗作宾语去哪里度过周末还没有被决定出学习必备 欢迎下载（2）强调动作的承受者，而不强调动作的执行者。例如：The window was _

20、（break）by Mike.窗户是迈克打破的。This book was _（write）by him.这本书是他写的。Eight hours per day for sleep must be guaranteed.每天 8 小时睡眠必须得到保证。歌诀：谁做的动作不知道，说出谁做的没有必要；动作承受者需强调，被动语态运用到。主动态和被动态指的是动词形式，是词法概念；而主动句和被动句则指的是句子结构，从而是句法概念。所谓主动句就是由主动态动词（词组）作谓语动词的句子，而被动句则是由被动态动词（词组）作谓语动词的句子。四、主动语态变被动语态的方法 （1）把主动语态的宾语变为被动语态的主语。（2

21、）把谓语变成被动结构（be过去分词）（根据被动语态句子里的主语的人称和数，以及原来主动语态句子中动词的时态来决定 be 的形式）。（3）把主动语态中的主语放在介词 by 之后作宾语，将主格改为宾格。例如：All the people _（laugh）at him.He was _（laugh）at by all people.They _（make）the bikes in the factory.The bikes are _（make）by them in the factory.歌诀：宾变主，主变宾，by 短语后面跟。谓语动词变被动，be 后“过分”来使用。等动词后常接带的动词不定式作宾

22、语补足语那什么时候把省略呢常见的有人正在问口唱歌在被动语态中这些不定式中被省略的要还原如他被要载如你能让我看看如何关电脑吗作宾语去哪里度过周末还没有被决定出学习必备 欢迎下载 五、含有情态动词的被动语态 含有情态动词的主动句变成被动句时，由“情态动词be过去分词”构成，原来带 to 的情态动词变成被动语态后“to”仍要保留。歌诀：情态动词变被动，情态加 be 加“过分”，原来带to 要保留。例如：We can _（repair）this watch in two days.This watch can be _（repair）in two days.You ought to _（take）it

23、 away.It ought to be _（take）away.They should _（do）it at once.It should be _（do）at once.六、含双宾语的主动结构变被动结构 口诀：如遇双宾语，最好变间宾。如若变直宾，be done后加 to(或 for)含有双宾语的主动句改为被动句时，应将其中一个宾语改为被动结构的主语，另一个宾语仍保留在原处。一种情况是把间接宾语（指人）变为主语，直接宾语（指物）不变；另一种情况是把直接宾语（指物）变为主语，间接宾语（指人）不变，这时，间接宾语前通常加介词 to，有时加 for。例如：1.My father gave me a

24、 new book on my birthday.I was given a new book（by my father）on my birthday.（间接宾语作了主语）A new book was given to me（by my father）on my birthday.（直接宾语作了主语）2.Father bought me a new coat.I was bought a new coat.（间接宾语作了主语）等动词后常接带的动词不定式作宾语补足语那什么时候把省略呢常见的有人正在问口唱歌在被动语态中这些不定式中被省略的要还原如他被要载如你能让我看看如何关电脑吗作宾语去哪里度过周

25、末还没有被决定出学习必备 欢迎下载 A new coat was bought for me.（直接宾语作了主语）七、补充 一些宾补动词如 make,see,hear等在主动语态中可以接动词原形（实为省略 to 的动词不定式）作为宾语补足语的动词在变被动语态是一定要注意恢复 to。如：He made me stand outside.I was made to stand outside（by him）.I saw him play football.He was seen to play football（by him）.有一个顺口溜方便记忆：宾补动词真奇怪，to 在句中像妖怪。主动句中 t

26、o 走开，被动句中 to 回来。小小练习（）1.Basketball _after school twice a week.A.is played B.will be played C.was played（）2.A lift _ to go up and down every day.A.is used B.are used C.be used（）3.Shoes _ in the shop last year.A.was sold B.is sold C.were sold（）4.In this game their hands _.A.not be seen B.be not seen C
