今天做题目,遇到了两题相反的选择,瞬间让我对于to的理解,充满了混乱,题目如下
  __ The doctor advised his patient _____ lots of fluid.
     (1) to drink  (2) drink  (3) drinking  (4) drank
      答案是(1),我也选(1),理由有两个 a. to + V 有表未来的意味,
                                       b. 句中有第二个动词或以上时,须用不定词
  __ You shouldn't let the new assistant _____ tomorrow's presentation.
     (1) give  (2) given  (3) to give  (4) giving
     依照以上a.与b.的理解,所以我选(3),答案却是(1),为什么....
     我试着查询网络上有关不定词的用法,但依然无法为我解答,还请教版上的各位
