简单的就分为以下这两类，一、动副短语可以分开。
动副短语由动词加副词构成，有的相当于一个及物动词，有被动语态，可以支配一个宾语，如果宾语是人称代词，代词放在动词和副词之间，如果宾语为名词或不定代词，则可以放在短语动词的后面，也可以放在中间。
如：He picked the book up. He picked it up.又如：work out 制定出win over 说服wipe out 消灭turn out 赶出来，结果是turn on 打开有的相当于一个不及物动词，不能支配任何宾语，无被动语态。
The plane took off despite the fog.The war broke out in 1980 and lasted eight years.又如：break down 出故障come to 苏醒drop out 退出give in 让步knock off 停工 二、动副介短语不可分开。
动副介短语由动词加副词加介系词构成，支配宾语的时候宾语放在介系词后面，不可分开，如：Please keep out of her affairs.The old law must be done away with.The old should keep up with the times.又如：catch up with 赶上come down with 患date back to 追溯到get along with 与……相处go on with 继续。
