会考英语知识点

在河南的中考英语考试中，会考到哪些知识点呢？下面是我收集整理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 句子 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 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 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 don’t 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 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 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 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)

2. 常用介词的用法辨析

(1)表时间的介词

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。

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：
