put the things on the table.这里on the table 是一个状语,
Just put all the things where they were.与之类同,是一个祈使句,put是谓语动词,all the things宾语,句子主干完整.
不过是将原来的on the table 变成了一个句子,故称状语从句.
是地点,所以选where
辨析一下,以下是定从.where we put them yesterday.是定从.先行词是table.
put all the things on the table where we put them yesterday.
