不定式后置定语

在某些句型结构中可用动词不定式作后置定语。例如： 
　　1) I have tons of letters to answer. 我有很多信要回。 
　　2)She needed someone to take care of her baby. 她需要人照看她的婴儿。 
　　3) They were the first to bear hardships, the last to enjoy comforts. 他们吃苦在前，享受在后。 
　　4) He is a nice man to work with. 他是个好相处的人。

　　6) There will be a very important person to come to our school this weekend. 本周末有个重要人物来我们学校。 

3.The conduct represented in the recently published article does not meet the standard that should be set by a commanding general.

这句话的主干是：The conduct does not meet the standard.represented是过去分词做后置定语，修饰conduct。that should be set是定语从句，修饰standard。
