双重介词根本就不是介词短语,是不相干的两个概念,例子如下:
from behind,from under.(双重介词)
in the room.on the desk (介词短语)
I like the book on the desk.(介词短语作的定语)
He is singing in the room.(介词短语作地点状语)
Tom is in the room.(介词短语作表语)
I saw him at work.(介词短语作宾语补足语)
双重介词短语多数时候做状语,很少作其它成分.如下例:
A cat rushed out from under the bed.(from under the bed为双重介词短语作状语)���ʣ�˫�ؽ�ʶ��������״�ﻹ����ʲô�ɷ֣���Щ���ӣ�лл�� 大多数时候,双重介词短语作状语,作其它的句子成分时少见,现在还真想不出恰当的例句。不好意思!
