初一英语必须掌握的知识点整理合集 1
1.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)
2.常用介词的用法辨析
(1)表时间的介词
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 ninettenth 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。
ince, 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.
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
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.
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.
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.
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.

1. 现在完成进行时的定义
现在完成进行时表示某动作从过去某个时间开始,一直延续到现在,并且还有可能持续下去。如:
We have been waiting for him for two hours.
2. 现在完成进行时的结构
have /has been + doing
3. 现在完成进行时的应用
现在完成进行时所用的时间状语:
this month / week / year, these days, recently / lately,
in the past few + 时间段, since +时间点, for + 时间段。如:
They have been building the bridge for two months.
They have been planting trees this month.
(一)表示动作的延续
The Chinese have been making paper for two thousand years.
中国有2000年的造纸历史。(动作还将继续下去)
I have been learning English since three years ago.自从三年前以来我一直在学英语。
(二)表示在说话时刻之前刚刚结束的动作。
We have been waiting for you for half an hour.
我们已经等你半个钟头了。(动作不再继续下去)
(三)有些现在完成进行时的句子等同于现在完成时的句子。
They have been living in this city for ten years.
They have lived in this city for ten years.
他们在这个城市已经住了10年了。
I have been working here for five years.
I have worked here for five years.
我在这里已经工作两年了。
(四)大多数现在完成进行时的句子不等同于现在完成时的句子。
I have been writing a book.(动作还将继续下去)
我一直在写一本书。
I have written a book.(动作已经完成)
我已经写了一本书。
They have been building a bridge.

They have built a bridge.
他们造了一座桥。
(五)表示状态的动词不能用于现在完成进行时。
I have known him for years.
我认识他已经好几年了。
×I have been knowing...
这类不能用于现在完成进行时的动词还有:love爱,like喜欢,hate讨厌,等。
4. 现在完成进行时与现在完成时的区别
(1) 现在完成时强调动作的完成,而现在完成进行时强调动作的延续,因此,表示动作的'完成,只能用现在完成时,而不能用现在完成进行时。如:
He has changed his idea.
(2) 在表示动作的延续时,虽然既可用现在完成时,也可用现在完成进行时,但现在完成进行时强调动作的进行。因此在需要明确表示动作还要持续下去时,应用现在完成进行时。如:
We have been studying here for two years.
(3) 有些延续性动词(如 keep, learn, live, stay, study, work等),用于现在完成时或现在完成进行时的区别不大。如:
I have lived here for many years.
=I have been living here for many years.
我在这儿住了多年了。
