英语语法知识难点--短语动词（六）
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：
All his money added up to no more than $100.
After a short rest, he went on with his research work.
（４） 动词＋名词＋介词
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
常见的有take place, make friends等。这类短语动词用作不及物动词。如：
This story took place three years ago.
I make friends with a lot of people.
