介词短语有什么功能?在句子中作什么成分?
介词短语句法功能:
1.介词短语作表语:
He was with a friend.
他和一个朋友在一起。
注意:有些介词(如:because of)引出的短语通常只用作状语不用作表语。
误:His absence is because of the rain.
正:His absence is due to the rain.
但是,若主语是代词(不是名词),because of 引出的短语可作表语。
It is because of hard work.
2.介词短语作状语:
Don't touch it with your hands.
3.介词短语作定语:
This is reply to your letter.
这是他给你的回信。
This is the best way of doing it.
这是做此事最好的方法。
My love for you is deeper than the sea.
我对你的爱比海深。
4.宾语补足语:
I found everything in good condition.
我发现一切正常。
注意:用在宾语补足语的介词短语在相应的被动语态中则为主语补足语。
He was regarded as a hero.
他被看成是英雄。
5.介词短语作宾语:
A man stepped out from behind the wall.
一个人从墙后走来。
6.介词短语作主语:
Between 6 and 7 suits me.
六点到七点,对我比较合适。
After the exams is the time to relax.
考试后是轻松一下的时间。
注意:介词短语通常不作主语,尽管有时也像上面这样用主语,但也通常视为在一定上下文有所省略。
When are we going to have the next meeting?
我们下次什么时候见面?
—On Tuesday may be convenient.
星期二比较方便。
此句中On Tuesday 虽用作主语,但视为前面省略了meeting一词,Meeting on Tuesday may be convenient.
