2008年中考復(fù)習(xí)：初中英語動詞不定式

　　四、用作定語 句子的主語或賓語是動詞不定式的邏輯主語，不定式與其所修飾的名詞、代詞等存在邏輯的動賓關(guān)系時，用動詞不定式的主動式。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.動詞不定式所修飾的名詞是place, time, way等時，不定式與這些名詞呈現(xiàn)出動狀關(guān)系或同位關(guān)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，句子的主語是動詞不定式動作的對象，常用主動式。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、用作補語

　　動詞不定式作補語時，在主動語態(tài)句里補賓語，在被動語態(tài)句里補主語，句子的賓語或主語是不定式動作的邏輯執(zhí)行者。如果不定式是to be done，句子的賓語或主語就是邏輯承受者。

在主、被動語態(tài)句里用帶to的動詞不定式作補語的動詞主要有：要求允許提議(ask, allow, permit, advise)，期望邀請鼓勵(expect, suppose, invite, encourage)，教導(dǎo)告訴想要(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.動詞不定式作補語，在主動語態(tài)句里不帶to，被動語態(tài)句里帶to時多數(shù)動詞是感官動詞和使役動詞，包括四“看”：look at, observe, see, watch，三“讓”：have, let, make，二“聽”：hear, listen to，一“感覺”：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后接動詞不定式作補語，to可帶可不帶。一般說來，帶to表間接幫助，不帶to表直接幫助。在被動語態(tài)句里，或者用不定式的否定式作補語時要帶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等后面可以接帶to的動詞不定式作主語的補語。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)
