初三英语知识点 篇二

(一)need和dare的用法

need和dare既可用作情态动词，也可用作实义动词。用作情态动词时，主要用于否定句和疑问句。用作实义动词时，可用于各种句式。

Not one of them dared mention this. 他们谁也不敢提这件事。

2.用作实义动词You don't need to do it yourself. 你不必亲自做这件事。 We need to tell them the news. 我们需要把这消息告诉他们。

The table needs painting (to be painted.). 桌子需要油漆一下。

We should dare to give our own opinion. 我们要敢于提出自己的观点。

(二)情态动词后跟完完成这项工作的。

You may (might) have read about it. 你可能在报上已经读到这件事了。 You could (might) have been more careful. 你本来可以更细心的。

初三英语知识点归纳 篇三

【一般将来时】

表示将要发生的动作或存在的状态，常与表示将来时间状语如 next year,tomorrow等连用。注意：在Will you …？问句中，回答必须是 Yes,I will.或 No,I won't而不能用Yes,I shall. No, I shan't.来回答过去将来时：过去将来时不可以单独使用，它一般在宾语从句中作间接引语，表示从过去某一时间看来将要发生的动作或存在的状态。如：They told me that they would go to work in Guangdong.

【现在完成时】

顾名思义，现在完成时表示的是已经完成的动作，但动作造成的影响还在，常被just,already,yet 等副词修饰。如：He has already gone to Tianjin. 对现在造成的影响是他已经不在这儿了。现在完成时还可用来表示过去发生的动作一直延续到现在，常带有for或since等表示一段时间的状语。如：Mr Wang has lived here since 1983.表示说话前发生过一次或多次的动作，我们常用"过"来表示，常带有twice, once, ever, never等时间状语。如：I've never seen that film.

【过去完成时】

我们可以用"过去的过去"来概括过去完成时，表示过去某一时刻或某一动作之前已经完成了的动作，通常与by,before等构成的短语或when, before, after引导的从句连用。也可表示过去某一时间开始，一直延续到过去另一时间的动作，常和for或since构成的时间状语连用。用法和现在完成时大致相同，只不过又向前推了一个时态。

初三英语重要知识点 篇四

动词不定式

一。 定义：

由to+动词原形构成。不定式是一种非限定性动词。而非限定动词是指那些在句中不能单独充当谓语的动词，可分为不定式，动名词，现在分词和过去分词。“动词不定式”由动词+不定式构成。动词不定式在句中可以作句子除谓语之外的任何句子成分。动词不定式的被动形式除了一般形式外还有其完成式和进行式。

二。 动词不定式的构成：to+动词原形

(1)作主语

动词不定式作主语时，句子的谓语动词常用单数，其位置有以下两种： (1)把不定式置于句首。

如：To get there by bike will take us half an hour.

(2)用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。

如：

It+be+名词+to do It's our duty to take good care of the old.

It takes sb+some time+to do How long did it take you to finish the work?

It+be+形容词+for sb+to do It is difficult for us to finish writing the composition in a quarter of an hour.

It+be+形容词+of sb+to do It is stupid of you to write down everything (that) the teacher says.

It seems(appears)+形容词+to do It seemed impossible to save money.

在句型中，常用表示客观情况的形容词，如：difficult，easy，hard，important，impossible，necessary 等；

在句型中，常用careless，clever，good，foolish，honest，kind，lazy，nice，right，silly，stupid，wise等 表示赞扬或批评的词。

在不定式前的sb，可看作其逻辑主语。这一句式有时相当于Sb is+形容词+to do句式 ，如：It's kind of you to help me with my English.=You are kind to helpme with my English.

(3)举例

(1) It's easy (for me) to do that.我做这事太容易了

easy,　difficult,　hard,　important,　possible,　impossible,　comfortable,　necessary,　better;

the first,　the next,　the last,　the best,　too much,　too little,　not enough

1、It's so nice to hear your voice.

听到你的声音真高兴。

2、It's necessary for you to lock the car when you do not use it.

当你不用车的时候，锁车是有必要的。

(2) It's very kind of him to help us.　他帮助我们，他真好。

Kind,　nice,　stupid,　rude,　clever,　foolish,　thoughtful,　thoughtless,　brave,　considerate(考虑周到的),　silly,　selfish(自私的)

例句:

1、It was silly of us to believe him.　我们真愚蠢，竟然相信了他。

2、It seemed selfish of him not to give them anything.　他不给他们任何东西，这显得太自私了。

注意：

(1) 其他系动词如，look，appear等也可用于此句型

(2) 不定式作为句子成分时，动词用单数形式。

(3) 当不定式作主语的句子中又有一个不定式作表语时，不能用It is… to…的句型

(对)To see is to believe.　眼见为实。

(错)It is to believe to see.

三。 动词不定式作宾语

后面能接不定式作宾语的动词有：agree, ask, choose, decide, forget, hope, learn, want, wish, would like等。

1、We hope to get there before dark. 我们希望天黑以前到那儿。

2、The man decided to do it herself. 那个男人决定自己做那件事。

动词不定式作宾语的注意事项(2点)

1. 有些动词既可跟不定式作宾语，也可跟动名词作宾语，但含义不同：

remember to do 记住要做某事

remember doing 记得曾经做过某事

forget to do忘记要做某事

forget doing 忘记曾经做过某事

stop to do 停下来去做某事

stop doing 停止做某事

go on to do 继续做另一件事

go on doing 继续做原来在做的事

2. 不定式作宾语时，如带有宾语补足语，则要把不定式放到后面，用it作形式宾语，构成“主语+动词+it+宾补(形容词、名词)+不定式”结构。

如：He found it very difficult to get to sleep.他发现很难入睡。
