省略to 的动词不定式 1) 情态动词 ( 除ought 外,ought to): 2) 使役动词 let, have, make: 3) 感官动词 see, watch, look at, notice , observe, hear, listen to, smell, feel, find 等后作宾补,省略to。 注意:在被动语态中则to 不能省掉。 I saw him dance. =He was seen to dance. The boss made them work the whole night. =They were made to work the whole night. 4) would rather,had better: 5) Why… / why not…: 6) help 可带to,也可不带to, help sb (to) do sth: 7) but和except:but前是动词do时,后面出现的动词用不带to的动词不定式。 8) 由and, or和than连接的两个不定式,第二个to 可以省去: 9) 通常在discover, imagine, suppose, think, understand等词后,可以省去to be: He is supposed (to be) nice. 他应该是个好人。 10)but作介词,后接不定式结构时,前面谓语动词部分若含有do的形式时,but后的不定式要省去to,否则要带to。 He wants to do nothing but go out. He wants to believe anything but to take the medicine. 11)当两个或多个不定时短语由连词and,but或or连接时,后一个或几个不定式符号to常省略。但若表示对比、对照关系时,则不能省略。 He wants to move to France and marry the girl. The purpose of new technologies is to make life easier,not to make it more difficult. 12)不定式做表语时,一般要带to,但若主语部分中含有do的各种形式时,符号to可省去。 We've missed the last bus.All we could do now is walk home. 举例: He wants to move to France and marry the girl. He wants to do nothing but go out. 比较: He wants to do nothing but go out. He wants to believe anything but to take the medicine. 典型例题 1) ---- I usually go there by train. ---- Why not ___ by boat for a change? A. to try going B. trying to go C. to try and go D. try going 答案:D. why not 后面接不带to 的不定式,因此选D。 2) Paul doesn't have to be made ___. He always works hard. A. learn B. to learn C. learned D. learning 答案:B. make后接不带to 的动词不定式,当其用于被动时,to 不可省略。
