1. 小学英语知识点归纳
小学英语语法知识
一、现在进行时用法
主语在句首,am, is, are跟在后,
现在分词跟着走,其他成分不可丢。
表示动作正进行,句中now时间定。
一般问句,把be提到句前去。
否定句式也简单,be后只把not添。
二、特殊疑问句用法
What用途广,要问“什么”它当先。(What’s this?)
How开头来“问安”。(How are you?)
Who问“谁”。(Who’s that man?)
“谁的”Whose来承担。(Whose eraser is this?)
询问“某地”用Where。(Where is her cat?)
“哪一个”Which句首站。(Which one?)
三、动词加s或es方法歌诀
动词三单现在式,一般词尾加s。
s, x, ch, sh在词尾,直接加上es。
词尾若是字母o,加上es不用愁。
“辅音字母+y“来结尾,变y为i是正规。
es后边紧跟随,study→studies看明白。
四、“be going to”的用法口诀
be going to, 表打算,准备、计划将干。
表可能,有必然,通过现象来推断。
使用它,要注意,疑问形式be提前。
否定句,更简单,not放在be后边。
to之后,动原形,be的形式看人称。
下列词,要注意,come go和离去(leave)
进行时,表将来,牢牢记住莫忘记。

一、形容词性物主代词
1、形容词性物主代词8个:
My your his her its our your their
我的你的他的她的`它的我们的你们的他(她、它)们的
2、形容词性物主代词的特点:
1)译成汉语都有"的" eg:my 我的 their 他们的
2)后面加名词:eg:my backpack his name
3)前后不用冠词 a an the
This is a my eraser(错误)
That is your a pen(错误)
It's his the pen(错误)
3、I(物主代词)my you(物主代词)your he (物主代词)her we (物主代词) our
注:在变物主代词时,把原题所给的词加上的,再译成单词就可以了。
二、名词性物主代词
1、名词性物主代词和形容词性物主代词一样有8个:
Mine yours his hers its ours yours theirs
我的你的他的她的它的我们的你们的他(她、它)们的
2、 名词性物主代词的特点:
1)译成汉语都有"的"
2)后面不加名词
3)名词性物主代词=形容词性物主代词+名词
Eg:1、the pen is mine 钢笔是我的(mine=my pen)
三、单数的句子变成复数的句子
把单数的句子成复数的句子很简单:变法是把能变成复数的词变成复数,但a或an要把去掉。特殊疑问词、形容词、国家及地点通常不变。
Eg:把下列句子变成复数
1, I have a car ——we have cars
2, He is an American boy. ——They are American boys
3, It is a car ——They are cars

小学英语必考知识
一.动词be(is,am,are)的用法
我(I)用am, 你(you)用are,is跟着他(he),她(she),它(it)。单数名词用is,复数名词全用are。变否定,更容易,be后not加上去。变疑问,往前提,句末问号莫丢弃。还有一条须注意,句首大写莫忘记。
二.this,that和it用法
(1)this和that是指示代词,it是人称代词。
(2)距离说话人近的人或物用this, 距离说话人远的人或物用that。如:
This is a flower. 这是一朵花。(近处)
That is a tree. 那是一棵树。(远处)
(3)放在一起的两样东西,先说this, 后说that。如:
This is a pen. That is a pencil. 这是一支钢笔。那是一支铅笔。
(4)向别人介绍某人时说This is…, 不说That is…。如:
This is Helen. Helen, this is Tom. 这是海伦,海伦,这是汤姆。
(5)This is 不能缩写, 而That is可以缩写。如:
This is a bike. That’s a car. 这是一辆自行车。那是一辆轿车。
(6)打电话时,介绍自己用this, 询问对方用that。如:
—Hello! Is that Miss Green? 喂,是格林小姐吗?
—Yes, this is. Who’s that? 是的,我是,你是谁?
注意:虽然汉语中使用“我”和“你”,但英语中打电话时绝不可以说:I am…, Are you…?/Who are you?
(7)在回答this或that作主语的疑问句时, 要用it代替this或that。如:
①—Is this a notebook? 这是笔记本吗?
—Yes, it is. 是的,它是。
②—What’s that? 那是什么?
—It’s a kite. 是只风筝。

英语简单语法知识点:选择疑问句
选择疑问句:是指提出两个或两个以上可能的答案供对方选择的句式
一种是以一般疑问句的结构形式为基础,只是在语调上有所区别。
例如:Would you like coffee or tea?
这一类选择疑问句通常都是在前一个供选择的答案用低升调,后一个用降调;如果有两个以上供选择的答案,则在最后一个用降调,其余都用低升调。
例如:
Would you like a gin,or a whisky,or a `beer?
你是要喝杜松子酒,还是威士忌酒,还是啤酒?
这种语调上的特征往往是区别选择疑问句和一般疑问句的重要标志。试比较:
Shall we leave at six or `seven?
我们是 6 点动身还是 7点动身?
Shall we leave at six or seven?
我们在6,7点钟动身好吗?
上述第一例是选择疑问句,其答案只能是两者之一。
We shall leave at six/seven.我们将在6点/7点动身。
上述第二例是一般疑问句,它的答案只是 yes/no,而且并不肯定是6点或7点,甚至可能既不是6点,也不是7点:
Yes,we shall leave at six or seven.是的,我们将在 6, 7点钟动身。
No.We must leave earlier.不。我们必须早点动身。
另一种选择疑问句是以特殊疑问句的结构形式为基础的,也是在语调上有所区别。
例如:Which vase shall I use, the short one or the tall one ? The tall one.
在选择疑问句中的冠词用法。
Is she a housewife or a nurse?(她是一个家庭主妇还是护士?)
其中,or后的不定冠词a/an 不能省略。
英语简单语法知识点:特殊疑问句
特殊疑问句:以特殊疑问词开头,对句中某一成分提问的句子。
常用的疑问词有:what who whose which when where how why等。
可先分为3种:
疑问代词:what,who,which,whose,whom
疑问副词:when,where,why,how
疑问形容词:what(which,whose)+名词
特殊疑问句有两种语序
1.如疑问词作主语或主语的定语,即对主语或主语的定语提问,其语序是陈述句的语序:
疑问词(+主语)+谓语动词+其他成分。
如:Who is singing in the room﹖ whose bike is broken﹖
2.如疑问词作其他成分,即对其他成分提问,其语序是:疑问词+一般疑问句语序?如:What class are you in﹖
What does she look like﹖
Where are you from﹖
What time does he get up every morning﹖
How do you know﹖
注意:
1.回答特殊疑问句时,不能用yes / no,即问什么答什么,尤其是简略回答。如:
Who is from Canada﹖ Helen (is).
Where's the restaurant﹖ Near the station.
Why do you like koalas﹖ Because they are cute.
2.特殊疑问句一般读降调(↓)。
特殊疑问词
Who谁——Whose谁的(加se)
Why为什么
When什么时候
Where在哪里
Which哪一个
What什么 ( What time什么时间 What colour什么颜色)
How怎么样
How many多少{数量}
How much多少钱{价格},
多少(对不可数名词进行提问)
How long多长

“So + be/助动词/情态动词 + 主语” 表示前面所述内容也适用于另一人或物。be、助动词或情态动词的选择视前面陈述句中谓语动词的时态形式而定。例:
He likes football and so do I. 他喜欢足球,我也如此。
Jim was playing football just now and so was Tom. 刚才吉姆在踢足球,汤姆也在踢足球。
比较: “So +主语+be/助动词/情态动词.”结构,是用来证实前一句所表达的内容(起强调作用)。be、助动词或情态动词的选择视前面陈述句中谓语动词的时态形式而定。
A: It is very hot today. 今天天气很热。
B: So it is. 确实如此。
56. not only…but also… 不但……而且……
常用来连接语法作用相同的词、短语或句子。连接两个主语时,谓语动词要和紧靠它的主语在人称和数上保持一致。例如:
She likes not only singing but also dancing. 她不但喜欢唱歌,而且喜欢跳舞。
He is not only a good doctor but also a good father. 他不但是个好医生而且是个好爸爸。
Not only I but also he is hoping to go there. 不但我而且他也想去那儿。
57. prefer…to… 喜欢……胜过…...
prefer (doing) sth. to (doing) sth. 意为“两者相比更喜欢(做)其中之一”。在此结构中,to是介词,接名词或动名词,结构中前后所跟成分一样。例如:
He prefers tea to coffee. 茶与咖啡相比,他更喜欢茶。
He prefers doing shopping to going fishing.购物与钓鱼相比,他更喜欢购物。
58. 感叹句型
What (a/an) + adj. + n. +主语+谓语! How + adj./adv.+ +主语+谓语! 例如:
What a clever boy (he is)! =How clever the boy is! 这个男孩儿多聪明啊!
What a wonderful film we saw last night! 昨天晚上我们看的电影多精彩啊!
How lovely the weather is! 天气多好啊!
How hard he works! 他工作多么努力啊!
59. 祈使句型
祈使句型表示命令、请求、劝告等含义。说话的对象通常为第二人称,习惯上常省略。句末用句号或感叹号。肯定祈使句是:谓语动词用动词原形表示。否定祈使句是:在谓语动词前加do not(don’t)。例如:
Be here on time tomorrow. 明天准时到这儿来。
Say it in English! 用英语说!
Don’t be afraid! 别怕!
Don’t look out of the window! 不要朝窗外看!
60. 并列句型
用并列连词连接起来的两个或两个以上的简单句叫并列句。连接并列句常用的连接词有:and, but, or, so, however, not only…but also..., neither…nor..., either…or…等。例如:
I help her and she helps me. 我帮助她,她帮助我。
He is very old but he is in good health. 他年纪很大了,但他身体很好。
We must hurry, or we’ll be late. 我们得赶快走,不然就晚了。

5. 初三英语知识点,句型。比如定语从句等。
一、 定语从句
· 定语从句的定义
定语从句在句子中作定语,用来修饰一个名词、名词词组或者代词。
· 先行词和引导词
被修饰的名词、名词词组或代词叫做先行词;
在先行词和定语从句之间起连接作用的词叫做引导词。
引导词分为“关系代词”和“关系副词”。
· 关系代词和关系副词
关系代词有:who, whom, whose, that, which, as。
关系副词有:when, where, why。 注意:关系副词里面没有how。
如果要修饰方式,用that或in which引导,或者不用引导词。
I don’t like the way (that, in which) he eyed me.
我不喜欢他看我的那个样子。
· 关系代词:who
关系动词who在从句中主要作主语,在非正式语体里who还可以作从句中的宾语。
He is the man who wants to see you.
He is the man who I saw in the park yesterday.
· 关系代词:whom
He is the man (whom) I saw in the park yesterday.
(whom在从句中作宾语)
· 关系代词:whose
whose 用来指人或物,(只能用作定语, 若指物,它还可以同of which互换)。
They rushed over to help the man whose car had broken down.
Please pass me the book whose cover is green. (of which the cover/the cover of which)
· 关系代词:which(1)
which指物,在从句中作主语或宾语,作宾语时在非正式语体中可以省略。
They needed a plant which didn't need as much water as rice.
The farm (which) we visited yesterday is located in the suburb of Beijing.
· 关系代词:which(2)
当在which和that面前进行选择的情况下,一般情况下要选which:
1.在非限制性定语从句中通常用which作引导词,而不能用that做非限制性定语从句的引导词。
2. 修饰整个主句。
I never met Julia again after that, which was a pity.
3. 修饰谓语部分。
He can swim in the river, which I cannot.
4. 介词 + which
They are all questions to which there are no answers.
· 关系代词:that(1)
that多用来指物,有时也可以用来指人;在从句中作主语或宾语。指物的时候多用that,也可用which。
It’s a question that (which) needs careful consideration.
(指物,作主语。)
Who is the man that is reading a magazine under the tree?
(指人,作主语。)
The girl (that) we saw yesterday is Tom’s sister.
(指人,作宾语,可省略。)
· 关系代词:that(2)
在以下的情况中,只能用that作引导词,而不能用which作引导词。
1. 先行词为all , everything, anything, nothing, little等不定代词时。
All (that) she lacked was training.
2. 先行词被形容词最高级修饰时
This is the best film that I have ever seen.
3. 先行词被序数词和the last修饰时
4. 先行词中既有人又有物时
They talked about the teachers and the schools that they had visited.
5. 主句是含有who或which的特殊疑问句,为了避免重复时
二、 状语从句
1 地点状语从句
地点状语从句通常由where, wherever 引导。
Where I live there are plenty of trees.
Wherever I am I will be thinking of you.
2 方式状语从句
方式状语从句通常由as, (just) as…so…, as if, as though引导。
1) as, (just) as…so…引导的方式状语从句通常位于主句后,但在(just) as…so…结构中位于句首,这时as从句带有比喻的含义,意思是"正如…","就像",多用于正式文体,例如:
Always do to the others as you would be done by.
你希望人家怎样待你,你就要怎样待人。
As water is to fish, so air is to man.
我们离不开空气,犹如鱼儿离不开水。
Just as we sweep our rooms, so we should sweep backward ideas from our minds.
正如打扫房屋一样,我们也要扫除我们头脑中落后的东西。
2) as if, as though
两者的意义和用法相同,引出的状语从句谓语多用虚拟语气,表示与事实相反,有时也用陈述语气,表示所说情况是事实或实现的可能性较大。汉译常作"仿佛……似的","好像……似的",例如:
They completely ignore these facts as if (as though) they never existed.
他们完全忽略了这些事实,就仿佛它不存在似的。(与事实相反,谓语用虚拟语气。)
He looks as if (as though) he had been hit by lighting.
他那样子就像被雷击了似的。(与事实相反,谓语用虚拟语气。)
It looks as if the weather may pick up very soon.
看来天气很快就会好起来。(实现的可能性较大,谓语用陈述语气。)
说明:as if / as though也可以引导一个分词短语、不定式短语或无动词短语,例如:
He stared at me as if seeing me for first time.
他目不转睛地看着我,就像第一次看见我似的。
He cleared his throat as if to say something.
他清了清嗓子,像要说什么似的。
3 原因状语从句
比较:because, since, as和for
1) because语势最强,用来说明人所不知的原因,回答why提出的问题。当原因是显而易见的或已为人们所知,就用as或 since。
I didn't go, because I was afraid.
Since /As the weather is so bad, we have to delay our journey.
2) 由because引导的从句如果放在句末,且前面有逗 号,则可以用for来代替。但如果不是说明直接原因,而是多种情况加以推断,就只能用for。
He is absent today, because / for he is ill.
He must be ill, for he is absent today.
4 目的状语从句
表示目的状语的从句可以由that, so that, in order that, in case等词引导,例如:
You must speak louder so that /in order that you can be heard by all.
Better take more clothes in case the weather is cold.
5 结果状语从句
结果状语从句常由so… that 或 such…that引导,掌握这两个句型,首先要了解so 和 such与其后的词的搭配规律。
比较:so和 such
其规律由so与such的不同词性决定。such 是形容词,修饰名词或名词词组,so 是副词,只能修饰形容词或副词。 so 还可与表示数量的形容词many, few, much, little连用,形成固定搭配。
so foolish such a fool
so nice a flower such a nice flower
so many / few flowers such nice flowers
so much / little money. such rapid progress
so many people such a lot of people
( so many 已成固定搭配,a lot of 虽相当于 many,但 a lot of 为名词性的,只能用such搭配。)
so…that与such…that之间的转换既为 so与such之间的转换。
The boy is so young that he can't go to school.
He is such a young boy that he can't go to school
6 条件状语从句
连接词主要有 if, unless, as/so long as, on condition that 等。.
if 引导的条件句有真实条件句和非真实条件句两种。非真实条件句已在虚拟语气中阐述。
unless = if not.
Let's go out for a walk unless you are too tired.
If you are not too tied, let's go out for a walk.
7 让步状语从句
though, although
注意: 当有though, although时,后面的从句不能有but,但是 though 和yet可连用
Although it's raining, they are still working in the field.
3) ever if, even though. 即使
We'll make a trip even though the weather is bad.
4) whether…or- 不管……都
Whether you believe it or not, it is true.
5) "no matter +疑问词" 或"疑问词+后缀ever"
No matter what happened, he would not mind.
Whatever happened, he would not mind.
替换:no matter what = whatever
no matter who = whoever
no matter when = whenever
no matter where = wherever
no matter which = whichever
no matter how = however
注意:no matter 不能引导主语从句和宾语从句。
(错)No matter what you say is of no use now.
(对)Whatever you say is of no use now.
你现在说什么也没用了。(Whatever you say是主语从句)
(错)Prisoners have to eat no matter what they're given,
(对)Prisoners have to eat whatever they're given. 囚犯们只能给什么吃什么。
8 比较while, when, as
1)as, when 引导短暂性动作的动词。
Just as / Just when / When I stopped my car, a man came up to me.
2)当从句的动作发生于主句动作之前,只能用when 引导这个从句,不可用as 或 while。
When you have finished your work, you may have a rest.
3)从句表示"随时间推移"连词能用as,不用when 或while。
As the day went on, the weather got worse.
日子一天天过去,天气越变越坏。
9 比较until和till
此两个连词意义相同。肯定形式表示的意思是"做某事直至某时",动词必须是延续性的。否定形式表达的意思是"直至某时才做某事"。动词为延续性或非延续性都可 以。 正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。
肯定句:
I slept until midnight. 我一直睡到半夜时醒了。
Wait till I call you. 等着我叫你。
(在肯定句中可用before代替 Let's get in the wheat before the sun sets.)
否定句:
She didn't arrive until 6 o'clock.
Don't get off the bus until it has stopped.
1)Until可用于句首,而till通常不用于句首。
Until you told me, I had heard nothing of what happened.
直到你告诉我以前,出了什么事我一点也不知道。
2)Until when 疑问句中,until要放在句首。
---Until when are you staying? 你呆到什么时候?
--- Until next Monday. 呆到下周一。
注意:否定句可用另外两种句式表示。
(1)Not until …在句首,主句用倒装。
Not until the early years of the 19th century did man know what heat is.
直到19 世纪初,人类才知道热能是什么。
Not until I began to work did I realize how much time I had wasted.
直到我开始工作,我才认识到了我已蹉跎了几多岁月。
(2) It is not until… that…
10 表示"一…就…"的结构
hardly/scarcely…when/before, no sooner…than 和as soon as都可以表示"一…就…"的意思,例:
I had hardly / scarcely got home when it began to rain.
I had no sooner got home than it began to rain.
As soon as I got home, it began to rain.
注意:如果hardly, scarcely 或no sooner置于句首,句子必须用倒装结构:
Hardly / Scarcely had I got home when it began to rain.
No sooner had I got home than it began to rain.
三、 名词性从句
1).宾语从句(The Object Clause);
· 宾语从句
在句子中起宾语作用的从句叫做宾语从句。宾语从句的引导词和主语从句的引导词相同。宾语从句可以作及物动词的宾语,作短语动词的宾语,介词的宾语。
· 宾语从句:及物动词
Everybody knows that money doesn't grow on trees.
· 宾语从句:短语动词
Please go and find out when the train will arrive.
· 宾语从句:介词的宾语
I am interested in what she is doing.
· 宾语从句:否定的转移
I don't suppose you're used to this diet.
我想你不习惯这种饮食。
I don't believe she'll arrive before 8.
我相信她8点之前不会到。
2).表语从句(The Predicative Clause);
· 表语从句
在句子中起表语作用的从句叫做表语从句。表语从句的引导词和主语从句的引导词相同。
What the police want to know is when you entered the room.
This is what we should do.
That's why I want you to work there.
as if, as though, because也可用来引导表语从句。
She seems as if she had done a great thing.
It is because you eat too much.
· 虚拟语气:表语从句
主语是idea, notion, proposal, suggestion, request等名词时,作表语从句的动词为原形动词或should+原形动词。
My suggestion is that we (should) go and help him.
Our only request is that this should be settled as soon as possible.
3).同位语从句(The Appositive Clause)。
· 同位从句一般跟在某些名词如answer(答案),hope(希望),fact(事实),belief (信仰),news(消息),idea(主意;观念),promise(承诺),information(信息),conclusion(结论),order(命令), suggestion(建议),problem(问题),thought (想法)等后面。例如:
I had no idea that you were here.
She told us her hope that she would become a pianist.
He made a promise that he would never come late.
· 同位语从句:whether
whether可以引导同位语从句,而定语从句不能用whether作为引导词。
He hasn’t made the decision whether he will go there.
I have small doubt whether he is suitable for the job.
· 同位语从句:what
what可以引导同位语从句,而定语从句不能用what作为引导词
I have no idea what he is doing now.
· 同位语从句:how
how可以引导同位语从句,而定语从句不能用how作为引导词
It’s a question how he did it.
· 同位语从句和定语从句的区别(1)
同位语从句和先行词是同等的关系;而定语从句是用来修饰先行词,是从属的关系。
· 同位语从句和定语从句的区别(2)
that在同位语从句中没有词义,不充当句子成分;而在定语从句中充当主语、宾语等句子成分。
· 同位语从句和定语从句的区别(3)
whether, what, how可以用来引导同位语从句;而它们不能用来引导定语从句。
