1介词的用法
介词的功能
介词是一种虚词,用来表示名词或相当于名词的其它词语句中其它词的关系,不能单独使用。介词可与名词或相当于名词的其它词构成介词短语。介词短语可在句中作定语,状语,表语和宾语补足语。例如:
The boy over there is John’s brother. (定语)
The girl will be back in two hours. (状语)
Our English teacher is from Australia. (表语)
Help yourself to some fish. (宾语补足语)
常用介词的用法辨析
(1)表时间的介词
1)at, in on
表示时间点用at。例如:at six o’clock, at noon, at midnight。表示在某个世纪,某年,某月,某个季节以及早晨,上午,下午,晚上时,用in。例如:in the nineteenth century, in 2002, in may, in winter, in the morning, in the afternoon等。表示具体的某一天和某一天的上午,下午,晚上时,用on。例如:on Monday, on July 1st, on Sunday morning等。
2) since, after
由since和after 引导的词组都可表示从过去某一点开始的时段,但since词组表示的时段一直延续到说话的时刻,因而往往要与现在完成时连用。而after词组所表示的时段纯系过去,因而要与一般过去时连用。例如:
I haven’t heard from him since last summer.
After five days the boy came back.
3) in, after
in与将来时态连用时,表示“过多长时间以后”的意思,后面跟表示一段时间的词语。After与将来时态连用时,后面只能跟表示时间点的词语。After与过去时态连用时,后面才能跟表示一段时间的词语。例如:
He will be back in two months.
He will arrive after four o’clock.
He returned after a month.
(2)表示地点的介词
1)at, in, on
at一般指小地方;in一般指大地方或某个范围之内;on往往表示“在某个物体的表面”。例如:
He arrived in Shanghai yesterday.
They arrived at a small village before dark.
There is a big hole in the wall.
The teacher put up a picture on the wall.
2)over, above, on
over, on和above都可表示“在……上面”,但具体含义不同。Over表示位置高于某物,在某物的正上方,其反义词是under。 above也表示位置高于某物,但不一定在正上方,其反义词是below。On指两个物体表面接触,一个在另一的上面。例如:
There is a bridge over the river.
We flew above the clouds.
They put some flowers on the teacher’s desk.
3) across, through
across和through均可表示“从这一边到另一边”,但用法不同。Across的含义与on有关,表示动作在某一物体的表面进行。Throgh的含义与in有关,表示动作是在三维空间进行。例如:
The dog ran across the grass.
The boy swam across the river.
They walked through the forest.
I pushed through the crowds.
4) in front of, in the front of
in front of 表示“在某人或某物的前面”,在某个范围以外;in the front of 表示“在……的前部”,在某个范围以内。例如:
There are some tall trees in front of the building.
The teacher is sitting in the front of the classroom.
