初二英语下册知识点(精品11篇)。

初二英语下册知识点 篇1

宾语从句

结构:主语 + 谓语动词 + 宾语从句(主语 + 谓语动词 + 宾语/表语)

例句:----Im good at English. He says. (改为加宾语从句的复合句)

----He says Im good at English.

注意:①主句是一般现在时态,宾语从句的时态不受其影响。

例句:He says Im good at English now.

He says I was good at mathematics when I was young.

②主句是过去时态,宾语从句也要用过去时态。

例句:He said I was good at mathematics when I was young yesterday.

He said I was good at English now yesterday.

③宾语从句是客观真理时永远用一般现在时态。

例句:Our teacher says 24 hours make a day.

Our teacher said the sun gives us so many energy yesterday.

④动词原形不能作主语,必须用其 -ing 形式。

例句:She said helping others changed her life.

初二英语下册知识点 篇2

一、 This is ... speaking.

【句型介绍】 该句为打电话用语,用来进行自我介绍,This代表我,speaking可以省去。

Hello! This is Tom (speaking). 你好,我是汤姆。

【句式比较】 Who is that (speaking)? 你是谁?that用来询问对方是谁,speaking可以省去。 Is that ... (speaking)? 你是......吗?that也用来询问对方是谁, speaking也可以省去。

This is Mary (speaking). Who is that (speaking)? 我是玛丽,你是谁?

Is that Jane (speaking)? 你是詹妮吗?

【特别提醒】 this不能换成I, that不能换成you。

二、 hear sb. / sth. doing

【句型介绍】 意为\"听见某人 / 物正在做......\",句中doing为现在分词作宾语补足语,表示动作正在进行,强调一个过程。

Just then I heard someone crying \"Help! Help!\" 就在那时,我听见有人在喊\"救命啊!救命!\"

【句式比较】 hear sb. / sth. do sth. 听见某人 / 物做某事,句中do为不带to的动词不定式作宾语补足语,表动作已经结束,强调一个结果。

I heard him sing three songs. 我听见他唱了三首歌。

hear sb. / sth. done听见某人 / 物被......,done为动词的过去分词作宾语补足语,强调被动。

Do you often hear this song sung by him? 你经常听见他唱这首歌吗?

【特别提醒】 在这些句型中的hear可换成see, feel, watch等感官动词。


初二英语下册知识点 篇3

have fun doing sth.

【句型介绍】 意为\"做某事有乐趣\",其中have fun 相当于enjoy oneself,表示过得愉快。

1. 英语中的集体名词,如family, class, team等作主语时,若作为一个整体看,其后的谓语动词用单数;若强调其组成成员,谓语动词用复数。如:

My family is a happy one. 我家是个幸福的家庭。

My family are all watching TV. 我们全家人都在看电视。

2. 在比较级中,要注意than后面人称代词的格。

1)当句子中的谓语动词是不及物动词时,than后面的代词用主格还是宾格,在意思上通常没有区别。如:

He runs faster than I / me. 他跑得比我快。

They get to school earlier than we / us every day. 他们每天都比我们到校早。

2)当句中的谓语动词是及物动词时,than后面的人称代词用主格还是宾格在意思上就有差别了。试比较:

I like you more than he. (=I like you more than he likes you.) 我比他更喜欢你。

I like you more than him. (=I like you more than I like him.) 你和他相比,我更喜欢你。

3. 不定式作定语时,应放在被修饰词的后面,一般指一个还没有发生的动作。如:

Do you have anything to say about this? 有关这件事你有没有什么要说的?

4. 在比较句型中,than后面的谓语动词常常省略。也可以用相应的`助动词来代替与前面相同的谓语动词,以避免重复。如:

Tom does better at the lessons than I (do). 汤姆功课比我好。

She ate less than I (did) for breakfast. 她早饭吃得比我少。

5. You\'d better ... 是You had better ... 的缩写形式。 had better 为固定短语,意为\"好......\",后接动词原形,常用来提出建议或劝告,其否定形式是\"had better not + 动词原形\"。如:

You\'d better not stay there too long. 你好别在那里呆得太久。

We had fun playing computer games. 我们玩电脑游戏很愉快。

【句式比较】 have a good / nice / wonderful time doing sth. 做某事有乐趣

Did you have a good / nice / wonderful time visiting that country? 访问那个国家你们快乐吗?

【特别提醒】 句中fun为不可数名词,表乐趣,前面不能加不定冠词。

初二英语下册知识点 篇5

动词不定式(to do)的用法

1.作主语

为避免句子的头重脚轻,常用it作为形式主语,而真正的主语动词不定式后置。

常用句型:It +be+adj./n.+(for/of sb.) to do sth./It takes sb. some time to do sth.

2.作宾语

动词want, decide, hope, ask, agree, choose, learn, plan, need, teach, prepare常接动词不定式作宾语。

3.作(后置)定语

常用于“have/has+sth.+to do”或“Its time to do sth.”等结构中。

4.作宾语补足语

tell, ask, want, invite, teach, like, call等可接带to的动词不定式作宾语补足语,构成tell/ask/want /call/invite sb. to do sth.结构。

【注意】动词不定式作使役动词和感官动词的宾语补足语时应省去to:“一感(feel),二听(listen to, hear),三让(let, make, have,四看(look at, see, watch, notice),半帮助(help)”。

5.动词不定式作状语

主要用来修饰动词,表示目的,结果或原因。为了强调目的,有时可以把动词不定式放在句首,或在不定式前加in order (to) 或so as (to) “为了,目的是”。

5. 表语:紧跟系动词后面的成分。

6. 定语:修饰名词或代词的成分。

7. 状语:修饰形容词、副词、动词或句子的成分。
