Mr. Wang had his shoes worn out.

王先生的鞋穿破了。

worn out 是“穿破了”，不是“穿坏了”。

have sth. done 一定是“让别人做某事”吗？

【问】以前学have sth. done 这个句型时，意思是让别人做某事。这次课本练习题有个句子是When do the students have to have their poems completed? 这个句子是不是说“学生非要让别人帮他们完成诗歌?”have sth. done 不是“让别人做某事”吗?

【答】你这个问题提得好。这句话的意思应当是：“学生什么时候必须写完他们的诗歌？”显然是“自己写诗歌”，不是让人代笔。have sth. done 不一定全都是“让别人做某事”，有时候是主语自己去做，这要具体情况具体分析。这个句型的含义有3种情况，现分别举例如下：

    (1) 表示主语主动让别人去做的事情：

       When did you have your hair cut?

       Later, Catherine II had the Amber Room moved to the palace outside St Petersburg.(Unit 1, Book II)

    (2) 表示主语被动遭遇到不愿意发生的事情：

       She had her hands burnt when she was cooking supper.

       Tom had his pocket picked in the supermarket.

    (3) 表示主语自己做而不是让别人做的事情：

        After they had their homework finished, the children went out to play.

        Have your medicine taken three times a day. Don’t forget it.
