動詞與介詞、副詞等構(gòu)成的固定短語，叫短語動詞。主要有四類：

一、動詞+副詞

有的一般不跟賓語，如go ahead, fall behind, get up, lie down, go up, run out, give in, stay up等;有的可以跟賓語，如put out, carry out, give up, wake up, check in, eat up, fill in, find out, fix up, hand in, mix up, look up, make out, turn down, work out等。

注意：賓語是名詞時，放在副詞前面或后面都可以，但若作賓語的是人稱代詞時，就只能放在動詞和副詞之間了。如：

We’ve decided to put the meeting off (=put off the meeting) . 我們決定把會議推遲。

We’ve decided to put it off. 我們決定將它推遲。(不說put off it)

二、動詞+介詞

如ask for, care for, call for, break into, deal with, call on, look for等。后面必須接賓語。如：

I don’t care for tea. 我不喜歡喝茶。

三、動詞+副詞+介詞

如look forward to, put up with, looked up to, go in for, go along with, date back to, look down on, keep up with, add up to, run out of等。如：

She soon caught up with us. 她很快趕上了我們。

四、動詞+名詞+介詞

如take care of, pay attention to, make use of, make contribution to做出貢獻等。如：

Take care of your brother while I am away. 我不在的時候，你要照顧好你弟弟。
