2020云南军队文职考试大纲《英语》考点：短语动词(3)

这类短语动词相当于及物动词时，若宾语为名词，一般既可放在短语动词之后，也可放在动词和副词之间。若短语动词的直接宾语为代词，则位于动词与副词之间。例如：
to give it(指heat)out放出它(热量);
to keep them(指the molecules)apart使它们(分子)保持分离
但是某些表示及物的短语动词却具有自己的固定模式：不允许随便将副词放在宾语之后(除非是宾语为代词);有时有的不容许随便将副词放在宾语之前。例如：
They had given up hope.此句不能变为：They had given hope up.
Get that parcel off right away!(寄出)此句因为歧义的缘故不能把副词off放在宾语之前。及物短语动词get…off与动词get后面跟介词off意思不同。例如：
Get off that stool.
it's just been painted!
Get off that parcel right away!
I switched the light on and off.
I switched on and off the light.
Crying my eyes out.这个句子不能变为：crying out my eyes.
I was laughing my head off.这个句子不能变为：I was laughing off my head.
Sobbing my head out.这个句子不能变为：sobbing out my heart.
