1、河南中考英语知识点 在河南的中考考试中，会考到哪些知识点呢？下面是 _的河南中考英语知识点以供大家学习。 Since 用来说明动作起始时间，for用来说明动作延续时间长度。例如： I have lived here for more than twenty years.我住在这儿二十多年了。 I have lived here since I was born. 我从出生起就住在这儿了。 注意：并非有for 作为时间状语的都用现在完成时。 I worked here for more than twenty years. (我现在已不在这里工作。) I have worked here for
2、 many years.(现在我仍在这里工作。) 注意：用句型转换的方法，很容易排除非延续动词在有for/since结构的完成时中的误用。 1)(对) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now. 2)(错) Harry has got married for six years. = Harry began to get married six years ago, and is still getting
3、 married now. 显然，第二句不对，它应改为 Harry got married six years ago. 或 Harry has been married for six years. What的三种用法 引导名词性从句的what在从句中作主语、宾语、表语或定语。 (1)具有疑问代词性质的what：意为“什么，什么样的”。如： I dont know what he needs. 我不知道他需要什么。(what在宾语从句中作宾语) (2)在名词前表示感叹的what：意为“多么”。如： Only then did I recognize what silly mistakes I
4、 had made. 只是在那时我才意识到我犯了多么愚蠢的错误。(what在宾语从句中作定语) (3)具有关系代词性质的what：意为“所的”。 相当于“the+名词+that”或者all that，即好像是既包括了先行词也包含了关系代词，因此，有学者称之为关系代词型what。如： What (=The thing that) happened after that was interesting. 后来发生的事挺有意思。(what在主语从句中作主语) China is not what (=the China that) used to be. (what在表语从句中作表语) The boy
5、 dived into water and after what (the time that) seemed to be a long time, he came up again. 他跳进水里，过了好像很久之后，他才又从水里出来。(what在宾语从句中作主语) 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。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 Johns brother. (定语) The girl will be back in t
6、wo 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 1)at, in on 表示时间点用at。例如：at six oclock, 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 nitenth century, in xx, in may, in winter, in the morning, in the afternoon
7、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 havent 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
8、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 oclock. 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
9、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 teachers desk. 模板,内容仅供参考
