Grammar:Infinitive第1页不定式属于非限定动词。它除了不能做谓语外，在句中能够充当任何成份，能够作主语、表语、宾语、补语、定语和状语。不定式的用法第2页1.作主语:往往放在谓语动词之后,用it作形式主语,为了防止句子头重脚轻。

e.g.

Toseeistobelieve.Itisrighttogiveupsmoking.第3页2.作宾语:作宾语时假如还带有宾语补足语,往往把不定式放在补足语之后,而用it作形式宾语。

e.g.Hewantedtogo.Ifinditinterestingtostudy

English.

第4页3.做宾语补足语

e.g.Heaskedmetodotheworkwithhim.

在feel,hear,listento,lookat,notice,observe,see,watch,have,let,make等词后补足语中,不定式不带to。不定式作宾语补足语省略to情况有以下口诀:一感二听三让五看半帮助。

不过这些句子假如变成被动结构时,就必须带上to。

第5页e.g.

Ioftenhearhimsingthesong.

Heisoftenheardtosingthesong.第6页4.

作定语e.g.Ihavesomebooksforyoutoread.看成定语不定式假如是不及物动词,或者不定式所修饰名词或代词是不定式动作地点,工具等时,不定式后面必须有对应介词。e.g.Heislookingforaroomtolivein.第7页看成定语不定式所修饰名词或代词是不定式动作承受者时,不定式即能够用主动语态,也能够用被动语态。但含义有所不一样。试比较:Haveyouanythingtosend?你有什么东西要(自己)寄吗?Haveyouanythingtobesent?你有什么东西要(我或他人)寄吗?第8页5.作状语,表示目标,原因,结果或条件。

e.g.Icameheretoseeyou.Wewereveryexcitedtofindnobodythere.Hehurriedtotheschooltofindnobodythere.

Tolookathim,youwouldlikehim.目标原因结果条件第9页6.作表语

e.g.Myjobistohelpthepatient.

注意:

主,表都是不定式,前者为条件,后者为目标或结果。

e.g.Tolearnalanguageistouseit.第10页不定式时态有：普通式、进行时、完成式和完成进行式。当不定式逻辑主语是不定式动作承受者时，不定式就要用被动形式。不定式时态和语态第11页1.不定式普通式所表示动作通常与谓语动作(状态)同时(或几乎同时)发生,或是在它之后发生。主动：e.g.I’mgladtomeetyou.被动：e.g.Therewasnothingtobedone.第12页2.假如谓语表示动作发生时,不定式表示动作正在进行,这时要用进行时。e.g.Iamverygladtobeworkingwithyou.第13页3.假如不定式动作发生在谓语动词之前,就要用完成时。主动：e.g.I’msorrytohavekeptyouwaitingsolong.

被动：e.g.Theroomwassaidtohavebeencleaned.第14页从A、B、C、D四个选项中，选出能够填入空白处最正确选项。1.Thereweremanytalentedactorsouttherejustwaiting______.A.todiscover
