Unit7—Unit8英语复习讲义稿编制:廖志高一、语法:动词不定式(The Infinitive)(一)、动词不定式的概念:to+动词原形(二)、什么时候动词用不定式?一个句子中不止一个动词,并且这个动词又不作谓语,一般情况下,这个不作谓语的动词常用动词不定式,即:to+动词原形。

﹡(三)、英语中常见的十个动词后动词不定式省to:(注意:被动语态中没有省to的情况。

)一、看:see, look, watch, notice;二、听listen, hear;三、感觉feel;四、使役let, make, help; (★help;后的动词不定式,既可带to+动词原形,也可省to,而后动词,仍用原形。

)﹡(四)、“疑问词+不定式”结构1.疑问词或疑问词组要放在不定式之前:如:A. What to do is a big problem.B. I know how to use the computer.C. Can you tell me which way to go .2.宾语从句与“疑问词+不定式”结构的转化:当主句中的主语和宾语从句中的主语是同一类人或物,而且引导该从句的引导词是which, what, how, where 等疑问词时,可将宾语从句中的主语删掉,将其转化为“疑问词+不定式”这一结构。

如:I don’t know what I should say.→I don’t know what to say.﹡(五)、如何对不定式划线提问A.当不定式放在及物动词或相当于及物动词的动词短语后时,对不定式提问用疑问词what. 如:●I know where to go .→What do you know?●She asked me when to start.→对不定式提问用疑问what did she ask me ?B.当不定式放在不及物动词后一般表目的,对不定式提问用疑问why.如:I went there to buy some candies. →why did you go there?﹡(六)、注意:see sb. do (doing)看到某人(正在)做;hear sb. do (doing) 听到某人(正在)做;watch sb. do (doing ); 观看某人(正在)做;▲上述三组词组中,如果强调当时正在后就用动词ing 形式;反之,后就用省to的动词原形。

概说
动词不定式(to do)是初中英语课的 一个重点,也是中考要考查的一个项目。 动词不定式属于非谓语动词的一种形式, 很多同学经常把它和谓语动词混在一起,
掌握起来有困难。下面我们对动词不定 式的用法做简单归纳,帮助同学们记忆
动词不定式的主要用法 一、动词不定式在句子中不能独立 充当谓语, 没有人称和数的变化。 二、动词不定式是由“to+动词原形” 构成(有时可以不带to)。动词不定式的 否定形式是“not+动词不定式”(此时 not不能再与助动词连用)。
巧记动词不定式作宾语歌诀:
• 想要拒绝莫忘记
• (want, refuse, forget) • 需要努力就学习 • (need, try, learn) • 喜欢帮助加同意 • (like help agree ) • 希望决定后开始 • (hope, decide, begin, start)
点击规律:在find \ feel \ think\ consider
+ 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。
I found it very difficult to get a job. (it为形式宾语)
如:
The man downstairs found it difficult to get to sleep.
• You must remember to lock the door when you leave
动词不定式基本用法口诀
• 不定式有标记, to与动原连一起。 • 没有人称数变化, 动词特点它具备。 • 主宾定状表状语, 惟独作谓不可以。 • not加上不定式, 否定结构要牢记。 • 疑问词与不定式, 构成短语有意义。 • 仔细推敲多思考, 准确判断有依据。

初二英语动词不定式讲义和练习 附带答案

初二英语动词不定式讲义和练习 附带答案

初二年级英语动词不定式讲义和对应练习动词不定式是由“不定式符号to+动词原形”构成的一种非谓语动词结构。

有些动词不定式不带to,动词不定式可以作句子的主语、表语、宾语、定语、补语、状语或单独使用。

一、用作主语直接把动词不定式置于句首的情况不多,多数情况用it作形式主语,把真正的主语——动词不定式置于句末,特别是不定式短语较长时(有时在不定式的前面还会用for sb.表示不定式的逻辑主语)。

动词不定式作主语,谓语动词用第三人称单数形式。

带疑问词的不定式短语作主语常置于句首,复合不定式结构作主语常置于句末。

如:1、把不定式置于句首。

如:To get there by bike will take us half an hour.2、用it作形式主语,把真正的主语不定式置于句后,常用于下列句式中。

如:①It+be+名词+to doIt's our duty to take good care of the old.②It takes sb + some time +to doHow long did it take you to finish the work③It+be+形容词+for sb+to do 逻辑主语It is difficult for us to finish writing the composition a quarter of an hour.④It+be+形容词+of sb+to do“It is stupid of you to write down everything”, the teacher says.注意:在③中,常用表示客观情况的形容词,如:difficult, easy, hard, important, impossible, necessary 等;在④中,常用careless, clever, good, foolish, honest, kind, lazy, nice, right, silly, stupid, wise等表示赞扬或批评的词,强调对人的评价。

时态\语态主动被动一般式 to do to be done进行式 to be doing /完成式 to have done to have been done完成进行式 to have been doing /一、不定式作宾语,大致上有三种情况。

第11讲 非谓语动词:动词不定式(讲义)(解析版)

第11讲 非谓语动词:动词不定式(讲义)(解析版)
【答案】to walk
【思维建模】遇到设空处为动词的题时,若句中已有谓语动词且不存在并列谓语或从句的谓语,考虑设空词为非谓语动词。观察句子结构,it充当形式主语,则to walk作真正的主语。
【变式训练】Fortunately, nowadays it is much easier ________(make)eco-friendly lifestyle choices.
【易错提醒】有些动词用带to的不定式作补足语,但使役动词(make, let, have等)与感官动词(watch, hear, feel, notice, see等)用于主动语态时,作其宾语补足语的不定式省略to;但当这些词用于被动语态时,to不能省略(let除外)。
【解析】考查不定式。句意:牛本来是第一个过河的,但是他很善良,所以同意带着小老鼠过河。结合句意表示“同意做某事”可知短语为agree to do sth.。故填to carry。
【答案】to carry

动词不定式的用法讲义

动词不定式的用法讲义动词不定式是英语语法中的一个重要部分,它具有丰富的用法和多样的功能。

下面让我们一起来详细了解一下动词不定式的各种用法。

一、动词不定式的形式动词不定式的基本形式是“to +动词原形”,例如“to study”“to play”。

但在一些情况下,to 会被省略,我们后面会详细讲到。

二、动词不定式作主语动词不定式可以用作句子的主语,表示一个具体的、将要发生的动作。

例如:“To learn a foreign language well is not easy”(学好一门外语不容易。

)但需要注意的是,为了避免句子头重脚轻,通常会使用形式主语 it ,将真正的主语动词不定式后置,变成“It is not easy to learn a foreign language well”三、动词不定式作宾语很多动词后面可以接动词不定式作宾语,常见的有:want(想要),hope(希望),decide(决定),plan(计划),expect(期望)等。

例如:“I want to go shopping this weekend”(这个周末我想去购物。

)四、动词不定式作宾语补足语有些动词后面会接宾语和动词不定式作宾语补足语,常见的这类动词有:ask(要求),tell(告诉),allow(允许),enable(使能够)等。

例如:“The teacher asked us to finish the homework on time”(老师要求我们按时完成作业。

)五、动词不定式作定语动词不定式可以用来修饰名词或代词,作定语。

例如:“I have a lot of work to do”(我有很多工作要做。

)这里的“to do”就修饰“work”,表示“要做的工作”。

Lecture 2 Infinitive-----动词不定式1非谓语动词(Non-Predicate Verb):在英语中,不作句子谓语,而具有除谓语外其他语法功能的动词,叫做非谓语动词。

1.1 非谓语动词与谓语动词相似点有:1.如果是及物动词都可与宾语连用。

They built a house.They suggested building a house.2.都可被状语修饰。

The suit fits him very well.The suit used to fit him very well.3.都有主动与被动,“体”式(一般式、进行式和完成式)的变化。

He was beaten by his parents.He avoided being beaten by his parents.We have written composition.Having written the composition, we handed it in.4.都可有逻辑主语。

We started the work at once.The boss ordered us to start the work at once.We are Party members.We being Party members, the work was well done.1.2非谓语动词与谓语动词的不同点有:1.2.1非谓语动词可以有名词作用(如动词不定式和动名词),在句中作主语、宾语、表语。

1.2.2 非谓语动词可以有形容词作用(如动词不定式和分词),在句中作定语、表语或宾语补足语。

1.2.3 非谓语动词可以有副词作用(如动词不定式和分词),在句中作状语。

2 动词不定式的结构形式温馨口诀:动作同时一般式,有时还用进行式,前面动作完成式。

被动要有被动式,否定to前加not。

2.1一般式(动词不定式表示的动作与谓语动作同时或之后发生。

)I’m glad to meet you.(同时)He wants to be an artist.(之后)The matter to be discussed at the meeting is a hard nut to crack.2.2 进行式(动词不定式表示的动作与谓语动作同时发生。

)He seems to be reading in his room.(同时)2.3 完成式(动词不定式表示的动作发生在谓语动词之前。

)I regretted to have told a lie.I am sorry for the article not to have been finished in time.3 动词不定式的作用。

温馨口诀:主宾表定状,宾补能用上。

3.1 作主语To finish the work in ten minutes is very hard.To lose your heart means failure.动词不定式作主语时,常用it作形式主语。

It is very hard to finish the work in ten minutes.It means failure to lose your heart.3.2 作表语His job is to clean the hall.3.3 作宾语I hope to see you.如果不定式(宾语)后面有宾语补足语,则用it作形式宾语,真正的宾语(不定式)后置,放在宾语补足语后面。

He found it important to study English.也可以充当介词宾语。

I have no choice but to stay here.They did nothing except work.有时也可与疑问词连用。

He gave us some advice on how to study English.3.4 作宾补I saw him come in.3.5 作定语,放在所修饰的名词或代词后面。

He was the last guest to arrive. (主-动关系)He found a good house to live in. (动-宾关系)I have no wish to quarrel with you. (同位关系)如果不定式修饰名词time, place, way,可以省略介词。

He has no place to live.This is the best way to work out this problem.3.6 作状语He worked day and night to get money.(表目的)He arrived late to find the train gone.(表结果)They were sad to hear the news.(表原因)3.7 作主补She is known to be a good teacher.3.8 作独立成分To tell you the truth, I don’t like the way he t alked.4带to动词不定式做宾语4.1 要想干,同意办,愿意不愿意,决定尽量干。

A.要求,想要,希望:want wish hope expect intend meanB.同意:agree promiseC.意愿:care hate refuseD.决定,企图:determine decide attempt try manage4.2 其它动词:Afford aim appear arrange bother believe choose claim come consent dare demand desire decline elect endeavor fail hesitate offer happen help seek learn neglect pledge plan prepare pretend seem swear undertake volunteer wait long(渴望)5不带to的动词不定式的常用动词和结构:5.1温馨口诀:一感feel, 二听hear, listen to ,三让have, let, make, bid(旧用法:嘱咐、命令),四看see, look at, observe, watch;还有except 和but, 前面有实义动词do, to 略去;主语从句有实义动词do式,to有to无都可以。

其它不带to的不定式情况:5.2 在半助动词之后,如:be about to/ be able to/ be apt to/ be bound to/ be due to/ be going to / be liable to/ be obliged to/ be supposed to/ be sure to/ be to/ be willing to / had better/best/ have to/ have got to / come to / fail to / get to/ tend to /be certain to/ be (un)likely to / appear to / chance to / happen to/ seem to/ turn out to/ etc. (p210. 18.1.1/p220.19.1.2. b)直接加上不含to的不定式。

The boy has to make a living by begging.He is unwilling to help me with my English.He seems to be very disappointed.注:半助动词含有的“to”,不能看成小品词,而应该看成半助动词的一部分,不能分割。

5.3 在情态成语之后,直接加上不带to的不定式。

would rather/would sooner/would (just) as soon +than-/as-+do (宁愿…而不愿)may/might (just) as well do(不妨,可以)cannot but/ cannot help but(不能不,不由得不)The hero said: “I would rather die than surrender.”Since it’s a fine day we may as well have a walk.I cannot but choose to go.I would as soon stay at home.5.4 rather than/sooner than 用法。

5.4.1 rather than与sooner than同义,多与would连用,构成“would rather...than...”句式,均作“宁可…而不”解释,表示主观愿望,即在两者之中选择其一。

前者多见,置于句首时,其后跟不带to的不定式。

Sooner than marry him, she would earn her living as a waitress.Rather than lose the children, she would die.当rather than与sooner than出现于句中其他位置时,其后不定式既可带to也可不带to.I decided to go home by taxi rather than wait here.The manager believes it is important to invest in new machinery rather than to increase wages.5.4.2 rather than 不与would连用时,表示客观事实,意为“是……而不是……;与其……不如……”。

它连接的并列成分可以是名词、代词、形容词、介词(短语)、动名词、分句、不定式、动词等。

5.4.2.1连接两个名词或代词He is an explorer rather than a sailor.与其说他是一个海员,不如说他是一个探险者。

You rather than I are going to go camping.是你而不是我要去要野营。

注意:rather than 连接两个名词或代词作主语时,谓语动词应与rather than 前面的名词或代词在人称和数上保持一致。

5.4.2.2 连接两个形容词The sweater she bought was beautiful rather than cheap.与其说她买的这件羊毛衫便宜不如说它漂亮。
