1、中考英语非谓语动词专题复习一、知识点归纳（一）非谓语动词的基本形式动词：He asks meto help him often.谓语 非谓语谓语动词：时态/被动语态非谓语：do/ to do/ doing/ done（二）非谓语动词的判定非谓语动词一直是英语学习的难点，也是中考的常考点，主要为动词不定式和动名词，在单项填空、词形填空和词组翻译题型中均有涉及。学生在做此类试题时应先分析本题该用谓语动词还是非谓语动词，然后才能确定选用动词的哪种形式或者非谓语的哪种形式。如何确定使用动词的哪种形式具体讲解详见动词的时态，下面列举几种常见的判定非谓语动词形式的方法：如何判定本题该使用谓语动词还是非谓语

2、动词：判断句子是否缺少谓语。当句子缺少谓语时，该动词就用谓语动词形式。一般情况下，动词作谓语放在主语之后，如“I love you.”中，love就是谓语动词。当句中已有谓语动词又没有并列连词与所填动词并列时，该动词就用非谓语动词形式。非谓语动词可以在句子中作除谓语以外的任何成分，如主语、宾语、宾语补足语、表语、定语、状语及插入语。（三）非谓语动词的分类（不定式、动名词）1.不定式的构成不定式的基本形式为:to+动词原形,有时可以不用to,这里的to是不定式符号,本身无词义,动词不定式的否定形式是not+to+动词原形。动词不定式没有人称和数的变化。2.不定式的基本用法作主语：（1）动词不定式

3、作主语时,常用it作形式主语,而将真正的主语放在句末,避免句子头重脚轻。其结构为It+be+adj.+to do sth.To learn English well is useful.=It is useful to learn English well.（2）如果要说明不定式表示的动作的执行者,可以在不定式前加一个for短语。其结构为It+be+adj.+for sb.+to do sth.It is good for you to go out for a walk.（3）某些表示人的品质、特征等的形容词(如kind,good,nice,wise,clever,polite等)作表语时,

4、不定式之前可以加一个of短语,用来说明动作的执行者。其结构为It+be+adj.+of sb.+to do sth.Its not polite of him to speak to old people like that.（4）两个或两个以上的动词不定式并列时,第一个不定式带to,后面的不定式通常省略toTo go to sleep early and get up early is a good habit.作宾语：(1)不定式用在及物动词后作宾语,常见的及物动词有:begin,choose,continue,decide,expect,fail,forget,hate,help,hop

7、定语：(1)作定语的不定式,要放在它所修饰的名词或代词之后I have some clothes to wash.(2)如果不定式是不及物动词,且与它所修饰的词构成逻辑上的被动关系,则不定式要加上相应的介词He is looking for a room to live in.We have a lot of things to alk about.(3)当不定式修饰的名词是time,place或way时,不定式后面习惯上省略介词My grandma had no place to live(in)in the old days.(4)不定式修饰 something,anything,noth

8、ing时,放在它们的后面,如果something,anything,nothing有形容词修饰,词序是“something/anything/nothing+形容词+不定式”I had something cold to drink.作状语：(1)不定式作目的状语时可放在句首或句尾To be a good student，one must study hard.(2)和某些形容词连用构成“be+形容词+不定式”结构,作原因状语We are sorry to trouble you.(3)作程度或结果状语时,常与enough(表示肯定)或too(表示否定)连用He is old enough t

10、elf.那个男孩太小而不能照顾自己。enough to“足够”。如：He is old enough to go to school.他足够大能去上学了。Why dont you +省略to的不定式？=Why not +省略to的不定式？为什么不呢？如：Why dont you get her a photo album?=Why not get her a photo album?为什么不给她买个相册呢？had better+（not）+省略to的不定式。最好（不要）做如：Youd better not stay here today.你今天最好别待在这儿。Will you please+省
