1、第八讲 非谓语动词中考要求内容基本要求略高要求较高要求非谓语动词一、非谓语动词的三种形式；二、非谓语动词的用法；三、非谓语动词中需要注意的一些问题。考点梳理根据英语动词在句中是否独立用作谓语，可以把动词分为谓语动词和非谓语动词两种。谓语动词是指动词在句中独立作谓语时采用的形式，如各种时态的形式。非谓语动词是指动词在句中不独立作谓语时采用的形式，包括不定式、动名词和分词（现在分词、过去分词）三种。清单一、动词不定式1不定式的形式动词不定式的基本形式是“to动词原形”，称为带to 的不定式；有时，to 可以省略，称为不带to 的不定式。其否定形式为 not + (to)+ 动词原形。例：He wa

2、nted to sit down. 他想坐下。（带to 的不定式）Let him sit down. 让他坐下。（不带to 的不定式）这里的to 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。但是，不定式作为动词的一种形式，依然保留了动词的特点，即可以有自己的宾语、状语等，有时，还可以有某种时态的变化（如完成时形式）。不定式与其附属部分一起构成不定式短语，在句中充当一定的句子成分。例：to learn English, to work hard, to have waited a long time等。易错点：动词不定式否定形式：not + (to) + do2不

3、定式的基本用法动词不定式虽然是动词的一种形式，但是它却具有名词、形容词和副词的功能，因此在句中可以用作主语、表语、宾语、宾语补足语（宾补）、定语、状语等。考点 用作主语：不定式作主语时，常用it做形式主语，而将真正的主语放在句末, 其结构为It is + adj. + (for/of) +动词不定式。例：To learn a foreign language is not easy.-It is not easy to learn a foreign language. 学习一门外语并不容易。To help the poor is his duty.-It is his duty to hel

4、p the poor. 帮助穷人是他的责任。注意：在kind, good, nice, clever等表示人的品质的形容词后，不用for而用of。 如： Its very kind of you to help me. Its very clever of you to do like that.例：To see is to believe. 眼见为实。His wish is to become a pianist.To the doctor, the most important thing is to save lives.真题回放2009年北京中考完成句子:多吃水果和蔬菜对身体有好处。_

9、 a little earlier?KEY: Why not或者Why dont you 在find, think后跟不定式作宾语时，常用it代替，而将真正的宾语放在句末。We found it impossible to cross the river.（本句中的it 是形式宾语，不定式短语to cross the river 是真正的宾语。）考点 注意： 不定式常和疑问词what, which, when, where, how，who连用，相当于一个宾语从句的作用。 如： The teacher is telling the students what to do.

30、asked, live lived, study studied, stop stopped），不规则的变化请参见不规则动词表。（不规则动词变化部分需要学生特别记忆）2分词的基本用法 用作定语： 现在分词作定语表示所修饰的名词的特征，或修饰名词所做的动作。单个的现在分词作定语必须前置；现在分词短语则后置。现在分词短语作定语，相当于一个定语从句，都可以变成一个相应的定语从句。现在分词作定语所修饰的名词有主谓关系。例：He is a promising young man. 他是个大有前途的年轻人。I have a friend living in London. (=I have a frien

31、d who lives in London.)a sleeping boy = a boy who is sleeping， the rising sun = the sun that is risingHe is a young man with pleasing manner.The room was full of people waiting for the headmaster.过去分词作定语多表示被动意义和完成意义。动作发生在谓语动词之前。其前置和特征与现在分词相同。过去分词作定语所修饰的名词有被动关系或系表关系。例：He is a man loved by all.I hate

32、to read letters written in pencil.We need more trained nurses.Things seen from behind seem a little different. 从背后看到的东西显得稍有不同。 用作表语：分词用作表语时，已经完全形容词化了，可以被very, rather 等副词修饰，而且可以有比较等级。 现在分词作表语，表示主语的特征或和连系动词连用构成进行时态。例：The book is interesting.The present situation is more encouraging than ever before.Th

33、e girl is watering the trees.现在分词作表语一般可以译成“使、令的” 过去分词作表语，和连系动词一起表示主语的状态或表示被动语态（动词应是及物动词）。例：The glass is broken.She is quite pleased.The glass was broken by Li Hua.请比较：This cup is broken. How about that one? 这只杯子是破的，那只怎么样？（系表结构）The cup was broken by my brother. 杯子被我弟弟打破了。（被动语态）考点 同类别词组： interesting-i

34、nterested exciting-excited boringbored relaxingrelaxed embarrassing-embarrassed surprising-surprised 用作宾语补足语：考点 现在分词作宾语补足语，表示动作正在进行，动作是宾语发出的，主动的，多用于使役动词或感官动词之后。如：see, watch, hear, feel, smell, notice, find; have, get, leave, keep例：We saw a light burning in the window.I cant get the clock going again

35、.I saw him talking with the doctor.He kept the machine running for ten hours. 口诀：吾看三室两厅一感觉，半帮助打死也不吐。（let, make, help三个单词除外）易错点：have sb. do sth. = let sb. do sth. have sb. doing sth.=keep sb. doing sth.请比较：I saw the old man crossing the street. 我看见那个老人在过街。（表示动作正在进行）I saw the old man cross the street.

37、词、感官动词和like, want, wish, order 等表示“希望”“要求”等意义的动词后面。特别注意“have宾语过去分词”这一结构的用法。例：I have to have my hair cut.You should make yourself understood by all.We have never seen the mountain covered in snow. 我们从未见那座山被雪覆盖过。 用作状语：分词用作状语，具有多种语义。 现在分词作状语，多用来表示伴随、时间、原因、方式等。现在分词作状语它的逻辑主语是主句的主语。如果分词表示的动作发生在谓语动作之前，并且已经

38、完成，用现在分词的完成形式。例：They stood by the road, reading books.Having stepped into the cave, Crusoe lit a fire.Hearing /When hearing a noise, they stopped talking. (= When they heard.) 听到喧闹声，他们便停止了谈话。（时间状语）She sat there reading a newspaper. (= and read a newspaper.) 她坐在那里看报纸。（伴随状况状语） 过去分词作状语与现在分词作状语一样，可以表示伴随

39、、时间、原因、方式等。过去分词作状语必须注意它表示的动作是该句主语发不出来的或表示主语的状态，但其逻辑上的主语应是主句的主语。例：When (water is ) heated, water changes into steam.Deeply moved, she couldnt say a word. (= As she was deeply moved.) 她深受感动，一句话也说不出来。（原因状语）现在分词的完成式，否定式，被动形式：例：Having worked among the workers for many years, he knew them very well.Not ha

40、ving received an answer, he decided to write another letter to them.Can you see the building being built?Having been put into prison, he felt hopeless.温馨提示：现在分词与过去分词可采用图表法进行比较讲解:功能例句说明现在分词过去分词定语The girl standing in front of the classroom is my roommate.Please give me your written exercises.作定语，其逻辑主语

41、为其所修饰的词。作定语，其逻辑宾语为其所修饰的词。状语The teachers went out of the building, talking and laughing.Seen from the hill, our school looks more beautiful.分词的逻辑主语是句子的主语。表语The situation is encouraging.The boy is too excited to utter a word.表示主语的性质，特征表示某种状态补足语Yesterday Jim kept us waiting for a long time I heard Lily

42、 singing in the classroom.Hell have his hair cut tomorrow. 被补足的宾语或主语是其逻辑主语，即主动关系被补足的宾语或主语是其逻辑宾语，即被动关系重难点解析一、现在分词与动名词作宾语之比较 一些动词后只能用不定式作宾语，常见的这类词是表示命令、打算或希望的，这类动词有：agree, begin, choose, dare, decide, expect, forget, hate, hope, learn, like, love, need, offer, prefer, promise, refuse, remember, start,

43、 try, want, wish, would like等，常用的有would like, want, wish,expect, decide, plan, agree, refuse, learn,need。 口诀：想要决定学习，需要同意计划，希望不要拒绝。想要（would like, want）决定（decide）学习（learn）需要（need）同意（agree）计划（plan）希望（wish, expect, hope）拒绝（refuse） 常用接动名词做宾语的动词：口诀（适用高中）：完成实践值得忙（finish, practice, be worth, be busy）继续习惯别放弃

44、（keep on, be used to, give up）考虑建议不禁想（consider, suggest, cant help, feel like）喜欢思念要介意（enjoy, miss, mind）初中常考单词：finish, practice, enjoy, mind, keep等 温馨提示：be busy doing, be worth doing 既可以接动名词作宾语，又可以接不定式作宾语的动词。.意思差别不大的动词如下：begin, start 等：在begin, start, hate, like, love, prefer 等动词后，用动名词或不定式作宾语，意思上几乎没有什么区别。 口诀： 开始喜欢爱恨交织 （begin, start, prefer, like, dislike, love, hate）例：The teacher said, “You begin writing now,” and the children began to write.Will you start reading / to read?So you prefer living / to live abroad?有时，like 后接动名词时，表示经常性的爱好；后接不定式时，表示一次性的或独特的爱好。例：I like traveling and, especially
