  1) 情态动词 ( 除ought 外) 后。
          2) 使役动词 let, have, make后,感官动词 see, watch, look at, notice , observe, hear, listen to, smell, feel, find 等后。
          注意:被动语态中不能省去to.例如:
          I saw him dance. 我看见他跳舞。
          =He was seen to dance.
          The boss made them work the whole night. 老板让他们整夜干活。
          =They were made to work the whole night.
          3) would rather,had better句型后
          4) Why… / why no…句型后
          5) help 后可带to,也可不带to, help sb (to) do sth:
          6) but和except后。but前是实义动词do时,后面出现的不定式不带to.
          比较:He wants to do nothing but go out. 他只想出去玩。
          He wants to believe anything but to take the medicine. 除了吃这药,他什么都信。
          7) 由and, or和than连接的两个不定式,第二个to 可以省去:
          8) 通常在discover, imagine, suppose, think等词后作宾补时,可以省去to be.例如:
          He is supposed (to be) nice. 他应该是个好人。
          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。
