1、非谓语动词非谓语动词概念：在句中不充当谓语角色的动词形式，它的划分有两种标准（一）：不定式；分词（过去分词与现在分词） ；动名词 （二）：不定式；v-ing.形式；过去分词.一、考点聚焦1、非谓语动词的句法功能2、动词不定式复习中应注意的几个问题（2）带不定式作宾语的词语，构成 v.+ to do 形式。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、prefer、decide 、manage、try、arrange、determine、
2、desire 等。下列动词后可接疑问词+不定式，构成 decide what to do ,wonder how to deal with sth.等形式：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 to 不定式作宾补的情况：主语 + ask
3、/ require / tell / order / force / get / want / like/advise/allow/cause/consider/ encourage/forbid/force/intend/order/permit/persuade/remind/request/require/urge/warn/ask/wish+sb. to do. sth. 主语 + think / judge / suppose / believe / consider /imagine/consider + sb. + to be/to be doing/ to have done注

6、s 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.seem、 appear、be said、be supposed、be believed、be thought、be known、be reported等动词常用于上面句型。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）should like to / would lik
7、e 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。注意：表示“过去本想做某事但未做”的虚拟语气还可以用：（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 (to )go home.Im really puzzled what to think or (to
8、)say.特例：To be or 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(to) 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.比较：have nothing to do but do /have not

10、k 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：The boy wanted to ride his bicycle in the street, but his mother told him . A. not to B. not to do C. not do it D. do not toSusan is not what she used to be.You cam
