2008年中考复习：初中英语动词不定式

　　四、用作定语 句子的主语或宾语是动词不定式的逻辑主语，不定式与其所修饰的名词、代词等存在逻辑的动宾关系时，用动词不定式的主动式。如

　　1)I have so many chores to do today.(p.112)

　　2)I cant think of any good advice to give her. (p.31)

　　3)Basketball has also become a more popular sport for people to watch.(p.75)

　　2.动词不定式所修饰的名词是place, time, way等时，不定式与这些名词呈现出动状关系或同位关系。如：1)He needs time to do homework.(p.19)

　　2)Is that a good place to hang out？(p.88)

　　3)You want to know the best way to get around the city.(p.127)

　　3.在“there be...”句型里，句子的主语是动词不定式动作的对象，常用主动式。如

　　1)There’s just so much to see and do here.(p.49)

　　2)... but there are still many things to do there.(p.54)

　　五、用作补语

　　动词不定式作补语时，在主动语态句里补宾语，在被动语态句里补主语，句子的宾语或主语是不定式动作的逻辑执行者。如果不定式是to be done，句子的宾语或主语就是逻辑承受者。

在主、被动语态句里用带to的动词不定式作补语的动词主要有：要求允许提议(ask, allow, permit, advise)，期望邀请鼓励(expect, suppose, invite, encourage)，教导告诉想要(teach, tell, want)，等待希望愿意(wait for, wish, would like / love)。如

　　1)Id invite her to have dinner at my house.(p.29)

　　2)Teenagers should be allowed to choose their own clothes. (p.18)

　　3)Email English is supposed to be used on mobile phones.(p.101)

　　2.动词不定式作补语，在主动语态句里不带to，被动语态句里带to时多数动词是感官动词和使役动词，包括四“看”：look at, observe, see, watch，三“让”：have, let, make，二“听”：hear, listen to，一“感觉”：feel，一“注意”：notice。如

　　1)This picture makes me feel tense！(p.106)

　　2)Of course we want to see Liu Yu achieve his dreams.(p.24)

　　3.help后接动词不定式作补语，to可带可不带。一般说来，带to表间接帮助，不带to表直接帮助。在被动语态句里，或者用不定式的否定式作补语时要带to。如

　　1)... they can help you to compare two different products so that you can buy the one you really need.(p.106)

　　2)Using email English helps you write quickly. (p.100)

　　4.be said, be sure, happen, seem等后面可以接带to的动词不定式作主语的补语。如

　　1)He doesn’t seem to have many friends.(p.19)

　　2)Be sure not to miss them if they come to a city near you.(p.114)
