--------你問題中的兩者完全一樣,可互換.
原因是 put out 是 v.+ adv..這類結(jié)構(gòu)中 若賓語是名詞,可置于中間 (put the fire out) 或后面 (put out the fire).
再例子：
put your shoes on = put on your shoes
take your hat off = take off your hat
若賓語是代詞,則其只有一個位置：中間!
如：There was a fire; we couldn't put it out.
錯：There was a fire; we couldn't put out it.(錯錯錯)
再例：
These are your shoes; put them on.
錯：These are your shoes; put on them.(錯錯錯)
如果是 v.+ prep.不論賓語是名詞還是代詞,只有一個位置：后面!
例子：
對：I was looking for my dog when I saw the accident.(賓語是名詞,后置)
錯：I was looking my dog for when I saw the accident.
對：I've got a pet dog.Can you look after it for me when I'm away?I'll be back in three days.(賓語是代詞,也得后置!)
錯：I've got a pet dog.Can you look it after for me when...
