1、英语语法非谓语动词讲义在解非谓语习题时同学们遇到最大的困难有两个：一是如何判别是谓语动词还是非谓语动词；二是如何选用哪一种非谓语动词及其恰当的形式。例题一、All things _, the planned trip will have to be called off. A. considered B. be considered C. considering D. having considered (1998.6) 句子没有连词，说明所选结构不属于从句，那么就是独立主格做状语，根据动词与其逻辑主语之间的关系为动宾关系，答案应该是A。 例题二、The concerned mother th
2、rilled at the news of his son _ to college. A. had been admitted B. admitted C. having been admitted D. having admitted 消息表达的应该是个事件，说明不是被录取的孩子，介词of后不可能接从句，说明of后为动名词的复合结构，答案是C。 例题三._tired of Toms all-talk-no-action attitude, Julia decided to do the job all by herself. A) To get B) To have got C) Gett
3、ing D) Have got 一般来说，在句子中没有连接词的情况下, 逗号是无力连接两个句子的。据此，首先可以确定 这是一个简单句，非谓语动词短语放在句首作状语。依据非谓语动词短语get tired of与其逻辑主语Julia之间的主动关系，以及谓语动词与非谓语动词所表示的动作几乎同时发生，没有明显的先后顺序，可以断定应用现在分词一般式作原因状语,即“由于厌倦了Tom只说不做的工作态度”，故正确答案为C。例题四 The last bus (go)_, we had to walk home. Weather (permit)_, the spaceship will be launched
4、tomorrow evening. 这两个非谓语动词短语的逻辑主语都不是句子的主语，而是分别有它自己的逻辑主语，即“是 末班车开走了，而不是我们走了”,“是天气允许,而不是飞船允许”，这种现象或结构就是独立主格结构。依据非谓语动词与其逻辑主语的主动关系,正确答案分别为having gone和permitting。 例题五The work (finish) _, they may go home. The problem (discuss) _ at the meeting- room now, the workers had to wait outdoors. 同样，这两道题的结构也是独立主格
5、结构。依据非谓语动词与其逻辑主语之间的被动关系以及非谓语动词所表示动作发生的时间性，可以判断正确答案分别为finished(已完成)和being discussed(正在进行)。 例题六 _ that Bob had got promoted, his friends came to congratulate him. A) Heard B) Having heard C) Hear D) To hear 依据非谓语动词hear与其逻辑主语his friends之间的主动关系，以及前后句的逻辑关系，可以断定用现在分词形式来作时间状语，再根据现在分词的动作“听说”发生在主要谓语动词“来”之前，由
6、此判断应该用现在分词的完成式(只用作状语时使用)，意为“听说Bob已得到提升，他的朋友都来向他表示祝贺”，故正确答案为B。 非谓非谓语动词的三种形式名称形式用法不定式to do表目的、将来动名词doing表主动及现在分词done表被动及过去非谓语动词的形式变化非谓语形式构成时态语态复合结构否定式主动被动不定式一般式to doto be donefor sb. to do sth.或of sb. to do sth.在“to”前加not或never（不定式的否定形式）完成式to have doneto have been done进行式to be doing/完成进行式to have been

9、o, be worth, be busy, pay attention to, stick to两者都可以意义基本相同begin, start, like, love, hate, prefer, continue（接不定式多指具体的动作，接动名词多指一般或习惯行为）need, want, require（主语与动名词之间存在逻辑上的动宾关系，接动名词主动形式表示被动意义，若接不定式则应用被动形式）意义相反stop to do 停止手中所做的事，去做另一件事 stop doing 停止正在做的事意义不同remember/forget/regret to do（指动作尚未发生）remember/
10、forget/regret doing（指动作已经发生）go on to do（接着做另外一件事）go on doing（接着做同一件事）try to do（设法，努力去做，尽力）try doing（试试去做，看有何结果）mean to do（打算做，企图做）mean doing （意思是，意味着）cant help （to） do（不能帮忙做）cant help doing（忍不住要做）be considered to have done被认为已经做了considerto be认为是consider doing考虑做某事做宾补的非谓语动词比较分 类常见动词与宾语的逻辑关系及时间概念例 句不定
11、式ask, beg, expect, get, order, tell, want, wish, encourage主谓关系，强调动作将发生或已经完成I asked to be sent to the countryside.I heard him call me several times.have, notice, see, watch, hear, feel, let, make现在分词notice, see, watch, hear, find, keep, have, feel主谓关系，强调动作正在进行，尚未完成I found her listening to the radio.过
12、去分词动宾关系，动作已经完成，多强调状态We found the village greatly changed.做定语的非谓语动词比较分 类区 别例 句不定式与被修饰词往往有动宾关系，一般式表示将来，进行式表示与谓语动作同时发生，完成式表示在谓语动词之前发生I have a lot of papers to type.I have a lot of papers to be typed.I havent decided which hotel to stay at.(介词at不能丢)现在分词与被修饰词之间是主谓关系，表示动作与谓语动作同时发生the boiling water / the b
13、oiled waterthe developing country/the developed countrythe falling leaves/the fallen leaves过去分词与被修饰词之间是被动关系，表示动作发生在谓语动作之前，现已经完成或只表示状态注意：the bridge to be built 将建造的桥, the bridge being built 正在建造的桥,the bridge built已经建好的桥非谓语动词高考考点【考点一】不定式作状语不定式作状语时相当于一个状语从句，不定式作状语时往往用来作目的状语、结果状语或原因状语。1不定式用来作目的状语：作目的状语时
14、，不定式的逻辑主语通常也是全句的主语，这里往往译作“为了，想要”。To be a winner，you need to give all you have and try your best.要想成为赢家，你要付出所有并竭尽全力。 2不定式用于so.as to .，such.as to；enough to；too.to；only to等结构中作结果状语。（1）Would you be so kind as to lend me your bicycle?你能不能行行好，借给我你的自行车？（2）He is such a fool as to think that his strange behaviour can inflect others.他如此愚蠢以至于认为他奇怪的行为会影响他人。（3）He hurried to the booking office only to have been told all the tickets had been sold out.他匆忙去了售票处，结果被告诉所有的票已经卖完了。注意：“onlyto do”表示出乎意料的结果，tell 和主语He 之间存在动宾关系，因而应用不定式的被动结构。而现在分词作结果状语则表示自然而然的结果。 （4）His parents died，leaving him an orphan.他的
