16. had better (not) do sth. 最好(别)做某事
  had better为情态动词,其后需用动词原形。had better常用缩写,变成’d better,其否定形式是在其后直接加not。例如:
  We had better go now. = We’d better go now.
  我们最好现在走吧。
  You’d better not go out because it is windy.
  今天刮风,你最好别出去了。
  17. have sth. done 使(某事)完成 (动作由别人完成)
  sth.为宾语,done为过去分词作补语。例如:
  We had the machine repaired.
  我们请人把机器修好了。
  注意区分: We have repaired the machine. 我们(自己)已经修好了机器。
  18. help sb. (to) do sth./with sth. 帮助某人(做)某事,其中的to可以省略。例如:
  I often help my mother with housework.
  我常常帮助妈妈做家务。
  Would you please help me (to) look up these words?
  请你帮助我查查这些词好吗?
