1、Name Class Designer: Donnay 2018.3.28BOOK7 UNIT2 动词不定式 to do 用法与专练Learning aims: To get the students to review the usage of “to do” and apply it properly. 巧记动词不定式的用法 不定式有标记，to与动原连一起。 没有人称数变化，动词特点它具备。主宾定状表补语，唯独作谓不可以。 not加上不定式，否定结构要牢记。疑问词与不定式，构成短语有意义。 仔细推敲多思考，准确判断有依据。具体用法一、动词不定式的基本形式是(见课本)“不定式符号to+动词原

2、形”，有时可以不带to。例如： tosellflowersinthestreet 在街上卖花tospeakintheclassroom 在教室里讲话二、带疑问词的不定式短语 动词不定式前面可以带疑问代词what, which, who或疑问副词how, when, where, why等。这种结构起名词的作用，在句子里用作宾语、主语、表语等，或者单独使用。要注意的是，why后面的不定式不带to。例如：I dont know what to try next. （作宾语） Where to go is not decided yet.（作主语） 注意：单独使用时相当于一个特殊疑问句。 What

3、to do next?(=What will we / you do next?) Why go there?(=Why do we / you go there?)三、动词不定式的复合结构 动词不定式的复合结构是“for / of sb. to do sth.”，for / of引出不定式动作的逻辑主语。不定式复合结构的介词用for还是of，主要决定于前面形容词的性质。一般说来，of前面的形容词是careful, clever, foolish, good, kind, nice, wise等，既说明人的特性，又说明不定式动作的特性。for前面的形容词是dangerous, difficul

4、t, easy, hard, heavy, important, interesting, necessary等，一般说明不定式动作的特性，不说明人的特性。前面如果是名词用for。 例如：Its also probably a good idea for parents to allow teenagers to study in groups during the evening. Its kind of you to help me.不定式省to有四种情况：1、使役动词let,make,have等后接不定式。 例如： Lethimgo!Thebossmadethechildlaborswo

5、rkthewhole night.2、wouldrather,hadbetter后。例如： Youhadbetterstayathome.3、Why/Whynot后。例如： WhynothaveagoodrestonSunday? 4、感官动词see,watch,lookat,hear,listento,smell,feel,find，notice等后作宾语补足语，省to。例如： Isawhimdance. 注意：这些情况在被动语态中，不可省to.例如：Thechildlaborsweremadetoworkthewholenight.巩固练习： ( )1、He read the instru
