短语动词用法及示例：
　　I.要点
　　英语中有许多短语动词在意义上是一个整体，其用法有的相当于及物动词，有的相当于不及物动词，有的兼有及物动词和不及物动词的特征。英语短语动词的构成主要有以下六种：
　　(1)动词+介词
　　常见的有look for,look after,send for,care about,ask for,laugh at,hear of(from),add to,lead to等。这类短语动词的宾语只能放在介词后。如：
　　Don't laugh at others.
　　I didn't care about it.
　　(2)动词+副词
　　常见的有give up,pick up,think over,find out,hand in,point out等。这类短语动词的宾语如果是名词，既可放在副词前边，又可放在副词后边;宾语如果是人称代词或反身代词，则要放在副词前边。如：You'll hand in your homework tomorrow.
　　Please don't forget to hand it in.
　　(3)动词+副词+介词
　　常见的有look down upon,go on with,break away from,add up to,catch up with等。这类短语动词的宾语只能放在介词后边。如：

　　After a short rest,he went on with his research work.

　　常见的有take care of,make use of,pay attention to,make fun of等。这类短语动词的宾语只能放在介词后边。如：You should pay attention to your handwriting.
　　We should make full use of our time.
　　(5)动词+形容词
　　常见的有leave open,set free,cut open等。这类短语动词的宾语如果是名词，则宾语可放在形容词的前边，也可放在后边;宾语如果是人称代词或反身代词，则必须放在形容词前边。如：
　　The prisoners were set free.
　　He cut it open.
　　(6)动词+名词
