九年级英语知识点

1. 初三英语知识点（新目标的）

初中阶段的英语自无非就是这几个时态的变化嘛:
动词不定式：动词+(to)
do
sth.
一般现在时，动词原形。
一般过去时，动词过去式。
现在进行时，is/am/are+ving.
过去进行时，was/were+ving.
一般将来时，will+动原。
过去将来时，would+动原。
现在完成时，have/has+动词过去分词（have/has+been+ving现在完成进行时）
过去完成时，had+动词过去分词

2. 初三英语重要知识点有哪些

动词不定式一. 定义：
动词不定式是非谓语动词的一种，它没有人称和数的变化，在句子中不能独立作谓语，但它仍保持动词的特点，既可以有自己的宾语和状语。同时动词不定式又具有名词、形容词、副词的特征，在句中可以作主语、表语、宾语、宾语补足语、定语和状语
二. 动词不定式的构成：to+动词原形
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。
We hope to get there before dark. The girl decided to do it herself.
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
I remember seeing you somewhere before
Please remember to turn off the light when you leave.
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.
四. 动词不定式作宾语补足语 1. 后面能接to不定式作宾语补足语的动词有：ask, order, teach, tell, want, wish, help等。
The teacher told us to do Exercise 1.
I want both of you to go. We helped her (to) repair her bike.
2. 使役动词let, have, make及感官动词see, watch, notice, hear, feel等要以不带to的不定式作宾补。
Let’s have a rest. I saw him come in.
感官动词后既可跟不带to的不定式作宾补，也可跟v-ing作宾补，前者表示动作的全部过程已结束；后者表示动作正在进行。
I saw him come downstairs.我看见他下了楼。（说明他下楼了这件事）
I saw him coming downstairs.我看见他在下楼。（说明他下楼时的情景）
五. 动词不定式作状语
Later he left home to work in different cities.
He went to see a football match.
In order to catch the other students, I must work hard.
六. 动词不定式作定语一般放在所修饰的词的后面。
I need something to eat. Do you have something to read?
Tom was so excited that he had no word to say.
He is really a fool only to eat.
The man to stand here just now is our English teacher.
The doctor had no way to save the patient.
注意：（1）作定语的不定式是由及物动词组成，被修饰的名词或代词与不定式之间存在方位或方式关系需要有介词。
I am looking for a room to live in（方位关系）
We have many things to do experiments with. （方式关系）
（2）作定语的不定式是由“be + adj + prep”构成的动词短语。
Here there isn’t any book for me to be interested in.
We have done many things to proud of.
七. 动词不定式作主语To give is better than to receive.
To reach there on foot is impossible.
动词不定式作主语时，可以用it 代替，把实际主语不定式放在后面。
It’s better to give than to receive.
It’s impossible to reach there on foot.
It’s + adj + for sb. to do sth.
It’s not difficult for me to study English well.
It’s easy for him to work out this math problem.
在这个句型中，如果形容词与不定式的逻辑主语关系密切，并且形容词用来说明逻辑主语性质、品质、特点等，由of引出逻辑主语。这类形容词主要有nice, kind, good, wrong, right等。
八. 动词不定式和疑问词连用
动词不定式可以和疑问词what, which, how, where, when连用，构成不定式短语，可以作主语、宾语、表语、宾语补足语等。
How to do is still a question. Have you decided when to leave?
九. 动词不定式的否定形式
动词不定式的否定式是在to前加not；不带to的不定式则在动词前加not. 如：
Zhang Ming asked me not to stay at home all day.
My mother let me not do it by myself.
被动语态两种语态：主动语态和被动语态
主动语态（The Active Voice）表示主语是动作的执行者。
被动语态（The Passive Voice）表示主语是动作的承受者。
构成：承受者+助动词be+及物动词的过去分词+by+执行者
一般现在时：承受者+助动词am / is/are +及物动词的过去分词+by+执行者
一般过去时：承受者+助动词was / were +及物动词的过去分词+by+执行者
承受者+助动词shall / will be+及物动词的过去分词+by+执行者
承受者+助动词 have/ has been+及物动词的过去分词+by+执行者
承受者+ can /may/must/should +be+及物动词的过去分词+by+执行者
被动语态用法：
1）当我们不知道动作的执行者是谁，或者没有必要指出动作的执行者时，需用被动语态。
2）当我们需要强调动作的承受者时,常用被动语态。
3）如果需要说出动作的执行者, 用by引导出动作的执行者。
主动语态变为被动语态时，其谓语动词的时态要与原句时态保持一致，其谓语动词的数要与新主语保持一致。
主动语态变为被动语态时有以下几种情况：
1）主语＋谓语动词＋宾语 将主动语态的宾语变为被动语态的主语。
（主动）We bought a book yesterday.
（被动）The book was bought yesterday.
2）主语＋谓语动词＋间接宾语＋直接宾语
将主动语态中一个宾语变为被动语态的主语。多数情况下将间接宾语变为主语。如果直接宾语变为主语时，间接宾语前要加介词to / for。
（主动）He showed me a book yesterday.
（被动）I was showed a book yesterday.
（被动）The book was showed to me yesterday.
3）主语＋谓语动词＋复合宾语
含有一个由宾语加宾语补足语构成的复合宾语，变为被动语态时，将主动语态的宾语变为被动语态的主语，宾语补足语保留不变，成为主语补足语。
（主动）I found him a good pupil. （宾语补足语）
（被动）He was found a good pupil. （主语补足语）
4）短语动词变为被动语态
有些短语动词相当于一个及物动词，其后可以接宾语，因此它们也有被动语态，但短语动词是不可分割的整体，变为被动语态时不可去掉其后面的介词或副词。
（主动）We should look after the patients very well.
（被动）The patients should be looked after very well by us.
5）宾语从句变为被动语态
若主动语态中是宾语从句，变为被动语态时常用it作形式主语，而把真正的主语放在后面。 It’s said that he passed the exam.
被动语态应注意的几个特殊问题：
（1）不及物动词带介词和介词宾语，在变为被动语态时，仍然要带上介词。
（主动）The students in class listen to the teacher carefully.
（被动）The teacher is listened to carefully by the students in class.（2）当动词带有复合宾语时，并且宾补是省去“to”的动词不定式时，在被动语态中应加上“to”。
（主动）They make do all the work.
（被动）We were made to do all the work.
（主动）We often hear her sing English songs.
（被动）She is often heard to sing English songs.
（主动）I see him walk to school.
（被动）He is seen to walk to school.

③由if , whether 引导 表示一般疑问意义(带有是否、已否、对否等)

④由连接代词、连接副词(疑问词) 引导 表示特殊疑问意义

She wants to know if I have finished my homework. 她想要知道我是否已经完成了我的作业。

bit too careful of your health？你对个人的健康难道不是有点过于小心了吗？Look out！There’s danger ahead.当心！前面有危险。
2. At times an ad can lead you to buy something you don’t need at all.有时广告可能导致你买你根本不需要的东西。
疑点：at times= sometime，是副词性短语，表示事物发生的频率。如：He is late for school at times.他有时上学迟到。
难点：1)对含有at times的短语进行提问时，用How soon，如：How soon does he go to school late？At times. 2)句中lead意为“使得、导致”，常用于短语lead sb. to do sth.“导致某人做某事”如：What leads you to think so？
3.Soft lighting makes people look good，but it make food look bad.柔和的光线使人的脸色看上去很好看，但使食物看起来很难看。
疑点：look good/bad意思为“外表的颜色看起来好看/难看”，如：The traffic accident made him look bad.
难点：look fine/ well指看起来身体健康，如：You look better today than yesterday.你今天看上去比昨天好多了。
4. It makes me want to join a clean-up campaign.这让我想加入一次清扫大运动。九年级英语 Unit 15知识点 人教新目标版

Edison invented the electric lamp.爱迪生发明了电灯。

Today, corn is found all over the world.今天，全世界都有了玉米。
She found him a very good pupil.她发现他是个非常好的学生。
◎有时find和discover可以互相替代，意思相同。
His notebook was found/discovered in the desk.他的笔记本是在课桌里找到的。
2. Some of the swamps have become polluted. (P119)一些沼泽地受到了污染。
have become polluted 中的become是连系动词，polluted是过去分词。这种“系动词+过去分词”结构，意思上也接近被动语态。
The slodier got wounded(接近were wounded)in the battle.这几名战士在这场战斗中受了伤。
A few minutes later, the ground became/was covered with snow.几分钟后地上尽是雪。
3. They provide homes for many endangered animals... (P120)他们为许多濒临灭绝的动
疑点：注意join的用法：(1)join加入军队，政党，组织等，成为其中一员。 如：The next year he joined the union.第二年他加入了工会。(2)join加入某人，并一起进行某项活动。如：She joined her husband in his study.她与她的丈夫一块从事他的研究。
难点：与join意思相近的短语take part in也表示“参加……”，take an active part in积极参
Did you know when he would be back? 你知道他将会什么时候回来？
2. get v. 得到、买、到达； 3. make a telephone call 打电话
