小学英语语法知识点:动词不定式的否定式
          Tell him not to shut the window.
       
          She pretended not to see me when I passed by.
       
          我走过的时候,她假装没看见。
       
          典型例题
       
          1)Tell him ___ the window.
       
          A. to shut not   B. not to shut   C. to not shut   D. not shut
       
          答案:B。 tell sb to do sth 的否定形式为tell sb not to do sth.
       
          2) She pretended ___ me when I passed by.
       
          A.  not to see   B.  not seeing   C.  to not see   D.  having not seen
       
          答案:A。 pretend 后应接不定式。其否定形式为pretend not to do sth.。
       
          3)Mrs. Smith warned her daughter ___ after drinking.
       
          A. never to drive  B. to never driver C. never driving  D. never drive
       
          答案:A。warn sb to do sth. 的否定形式为warn sb not to do sth. 此处用的是否定词never.
       
          4) The boy wanted to ride his bicycle in the street,but his mother told him ____.
       
          A. not to  B. not to do  C. not do it  D. do not to
       
          答案:A。not to 为not to do it 的省略形式。可以只用to这个词,而不必重复整个不定式词组。及物动词do后应有名词、代词等,否则不对,因此B,D不对。
       
          5) The patient was warned ___ oily food after the operation.
       
          A. to eat no  B. eating not  C. not to eat D. not eating
       
          答案:C。warn一词要求后用不定式,此处为不定式的被动,否定形式为be warned not to do。
