1、语法复习专题(9)非谓语动词一、考点聚焦1、非谓语动词的句法功能名称语 法 功 能 主语宾语宾语补足语表语定语状语不定式动名词现在分词过去分词2、动词不定式复心中应注意的几个问题(1)不定式作表语与“be + to do sth.”的异同。不定式作表语说明主语的内容或性质。His job is to guard.(说明内容)be + to do sth.(表示按计划要做的事)(2)带不定式作宾语的词语。下列词语常不定式作宾语:afford、promise、refuse、expect、hope、learn、offer、wish、want、fail、plan、agree、forget、like、p
2、refer、decide、manage、try、arrange、determine、desire等。下列动词后可接疑问词+不定式:teach、decide、wonder、show、learn、forget、ask、find、out、advise、discuss等。(3)如何理解和使用不定式作宾补。动词see、watch、notice、hear、listen to、observe、feel、taste、smell、make、let、have等的宾补用动词原形,变被动时要加to,此时的不定式就是主语补足语。常用带不定式作宾补的几种情况:主语 + ask / require / tell / ord
3、er / force / get / want / like + sb.to do sth.主语 + think / judge / suppose / believe / consider /imagine/consider / feel + sb. + to be/ to have done主语 + call on / upon / depend on / wait for / ask for + sb.+ to do sth.(4)不定式作定语的特殊用法。下列词语后常接不定式作定语:chance、wish、right、courage、need、promise、time、opportuni
4、ty、way、the first、the second、the last、the only等。不定式作定语和所修饰的名词在逻辑上有主谓关系。There is no one to look after her.不定式与被修饰的名词在逻辑上有动宾关系。She is now looking for a room to live in.(5)不定式作状语的用法。不定式作状语,修饰动词,在句中表示行为目的、结果、原因。only to do表示出人意料的结果。We hurried to the classroom only to find none there .in order(not)to,so as
5、(not)to用来引导目的状语,enough,too, so as to do, such + 名词 as to do作结果状语,如:The girl was so kind as to help the old man off the bus.Im not such a fool as to believe that.(6)不定式的完成时的特殊用法。表示不定式中谓语动词发生的动作先于主句的谓语动词发出的动作。The novel was said to have been published.I regret to have been with you for so many years.se
6、em、appear、be said、be supposed、be believed、be thought、be known、be reported等动词常用于上面句型。此外,glad、happy、satisfied、sorry、surprised、disappointed后也接完成时,但要注意与一般时的区别。Im sorry to keep you waiting for a minute.对不起,请稍等。(说话时还未等)Im sorry to have kept you waiting.对不起,让你久等了。(说话时已等了很久)不定式的完成时还可表示“过去本想做某事但未做”的虚拟语气。(A)s
7、hould like to / would like to / would love to + 不定式的完成时。(B)was / were to + 不定式的完成时,表示该做某事或想做但未实现。(C)expect / hope / mean / promise / suppose / think / want/ wish + 不定式完成时,表示过去未曾实现的愿望。(7)不定式的省略。 同一结构并列由and或or连接。I want to finish my homework and go home.Im really puzzled what to think or say.特例:To be o
8、r not to be,this is a question.He is better to laugh than to cry.(表示对比)不定式作表语,其前面的主语从句中含有do时,后面的to省略。What he did was lose the game.句中含有动词do时,but、except、besides、such as等后面to可省略。即“前有do,后省to”。Dont do anything silly, such as marry him.主句含有不定式,后面有rather than, rather than后省to。Why not、had better、would rath
9、er、cant but等词后省to。如:He could not but walk home.(8)不定式的替代。多用在同一句或联系紧密的对话中,为了避免重复,作宾语或主补,宾补的不定式再次出现时,to后的内容常承前省略(只保留to即可)。但如果承前省略的不定式有助动用的have或be任何形式,后应该保留原形be或have。如:Susan is not what she used to be.You came late last night. You ought to have finished yourhomework.I know I ought to have.常见的有:Id like
10、/ love / be happy to.3、动名词复习中应注意的几个问题(1)动名词作宾语。下列动词后只能接动名词:suggest, finish, avoid, stop, cant help, mind, enjoy, require, practise, miss, escape, pardon, advise, consider, imagine, keep, appreciate, eacape, permit。下列动词短语接动名词:leave off, put off, give up, look forward to, feel like, have trouble / dif
11、ficulty(in) doing sth. devote to, get used to, pay attention to, be fond of, be worth。介词后要接动名词。what about、how about、without、be fond of、be good at等介词后接动名词。注意on / upon doing sth. = as soon as 引导的从中。作此意讲时on / upon后也可以接名词。如on his arrival。动名词作宾语和动词不定式作宾语的区别:begin, start, continue, like, love, dislike, ha
12、te, prefer, cant stand例 句解 析1. It began to rain. It began raining.2. It was beginning to snow.3. I love lying (to lie)on my back.4. I like listening to music, but today I dont like to.5. I don t prefer to swim in the river now.1. 意思无差别,但谓语动词用进行时,后面只跟不定式。2. 表示一种倾向多接动名词作宾语,如果表示某一特定的或具体的行动,多接不定式。rememb
