      省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。

      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。
