1.在“动词+副词”短语中,若宾语是名词时,则该名词既可放在动词与副词之间,也可放在副词之后;若宾语是代词时,则该代词只可放在动词与副词之间,不可放在副词之后。如:Its time for breakfast. Wake the boy up(the boy放在动词与副词之间。)Its time for breakfast. Wake up the boy.(the boy也可放在副词之后。)Its time for breakfast. Wake him up.(him只可放在动词与副词之间。)2. 在“动词+介词”短语中,其宾语无论是名词还是代词,都须放在介词后面加上介词后,才能构成一个相当于及物动词的短语。如:Listen to me.(不可说Listen me to或Listen me.)Look at the blackboard.(不可说Look the blackboard at.或Look the blackboard.)以上两点是二者的区别,那么如何判断动词后面的小品词是副词还是介词呢?
