初一上册英语语法
初中英语并不难学,只要掌握了诀窍 一切都易如反掌 这里 为你集锦了初一一年来的语法知识,希望对广大同学们有所帮助。
.初一
1.there be 句型 “有”指 “某地有某物”形式 :there is, there are
例:There is some food in the fridge。冰箱里有一些食物。
There are many books on the desk. 桌上有许多书。
区分:there is 用于修饰单数名词和不可数名词 ,例如:a book , an egg, milk, ice-cream .......
there are 用来修饰可数名词复数
如果要表达某处没有某物 则要用there be 句型的否定形式,即在there be 后加not ,即 there be not
形式:there is not (there isn't) there are not (there aren't)
例: There isn't any milk in a glass。
There aren't any vegetables in the fridge.
若表示是否有,则要用 there be 句型的疑问句 即把be 提前 Be there 形式 Is there , Are there
例:Is there any milk in the glass?
Are there any vegetables in the fridge?
注意:这里涉及some any 的用法 some 用于肯定句中,any 用于否定句和疑问句中。但是在表示请求的
疑问句中,是想要得到肯定答复的,要用some。例:Would you like some milk?
对于there be 疑问句的回答:肯定:Yes,there is\are. No,there isn't\aren't.
2.have\has got 有 指某人有某物
例:I have a dog.我有一只狗。
He has a sister and a brother.他有一个姐姐和一个弟弟。
区分 :have\ has: have用来修饰第一人称和第二人称和第三人称复数(I ,we ,they) has用来修饰第三
人称单数(she, he , it )
若表示某人没有某物,则要用否定形式,即在have\has got 后加not 即have not (haven't)got ,has not
(hasn't)got.
例:I haven't got a sister but i have a brother.
She hasn't got bright eyes and long hairs.
某人是否有某物则要用have\has got的疑问形式,Have\Has +sb.\sth. + got
Have they got a picnic at weekends?
Has the dog got a host family?
回答:肯定:Yes, i \we \they have. Yes , she\ he \ it has.
否定:No , i \ we \ they haven't. No, she \he \it hasn't.
注意:there be 和 have got 的区别 两者虽都指"有",但侧重点不同。
例:《1》There are some food in the fridge.
<2>The fridge has got some food.
虽然都是“冰箱里有食物”但(1)句侧重于食物,(2)句侧重于冰箱。
3.be(am is are)
用法:我用am 你用are is连着她他它,单数用is,复数用are
例:I am a stident. She is a beutiful girl. He is a child. It is a dog.
You are my teacher. They are my friends, The boys all are England.
be 的否定形式 直接加not 即 am not, are not , is not.
例:I am not an English. I am Chinese.
She isn't kind. They aren't my friends.
疑问形式把be提前 即 be+ 主语......?
例:Is he your father?
Are they going to have a party?
回答:肯定:Yes, I am. Yes,she \ he \it is. Yes , you \ we \ they are.
否定: No, I am not. No, she \ he \ it isn't. No , you \ we \ they aren't.
be的句式, 所用情况:
1》be + 形容词(adj.). 例:I am very happy.
2> be+ 名词(n.) 例:He is a boy.
3> be + 介词短语 例:She is in the school.
4> be+形容词短语 例: He is only 11 years old.
5> be+ 副词 例:Class is over.
4. 情态动词 can
can 可以 能够,表示某人能做某事 用法:can+v.原 不能做某事,则用can 的否定形式:
cannot (can't)+v.原
can没有人称和数的变化,因此谁能(不能)做某事都能用can
若表示某人是否能做某事 则要用can 的疑问形式,即can+sb.……?
例:I can speak Chinese. I can't speak English. Can you speak English?
He can swim but he can't play football.
Can she play the piano?
疑问句回答 :肯定:Yes, I \she \ you \ he \it \they \ we can.
否定:No, I \ she \ he \it \ you \ we \ they can't.
注意:can 表示“能力”时,指现在的能力,并不指过去或将来的能力。
5 . 情态动词would 想 主要用于 would you like to ...句型中,表示邀请。
例:Would you like to go to school with me ?
回答一般有两种形式:1 表示愿意:I' like \ love to. 2 拒绝:Sorry, 原因。
注意:would like to 本身并不表示邀请, 而是想要。例:I would like to some books.
另外,表示邀请还能说:Let's...... Shall we...... What \ How about.......
还要注意邀请时询问信息的表达方式:1)询问时间:When is... 2) 询问地点: Where is....
6 行为动词的一般现在时
用法:
1.如果表示某人经常性或习惯性做某事,则要用行为动词的一般现在时
He goes to school every day.
They eat dinner in the evening.
2.若表示某人现在的动态,也可用一般现在时。
I know him very well. 我和他很熟。
He likes English very much. 他非常喜欢英语。
若表示否定意义,若主语是第一人称或第二人称或第三人称复数,只要在谓语动词后加not,即do not
(don't) ,若主语是第三人称单数,则要在谓语动词后加does not (doesn't)
例:I don't go to school every day.
She doesn't goes to the shop every day.
You don' t sing vell well.
若表示是否经常做某事 则要用疑问意义,将do \ does 提前即可
例:Do you write a composition every day? 你每天写一篇作文吗?
Does it smell good? 它闻起来很香吗?
注意:行为动词的一般现在时中涉及了频度副词,用法:用于行为动词之前,be动词之后
常见的频度副词有:often ,always , usually , never ,seldom ,sometimes等
7.变法总结
名词变复数(1)一般在词尾加-s 例词:bags, vegetables , books
(2)以s , x , ch , sh 结尾的加-es 例词: watches , boxes , buses , brushes
(3)以o 结尾的加-es 例词:两人两菜:heroes 英雄 negroes 黑人 tomatoes 西红柿
potatoes 土豆
(4)以o 结尾的加-s 例词:zoos , zeros
(5) 以 辅音字母+y 结把y 变 i 加-es 例词:baby——babies ,city——cities
(6)以 f 或 fe 结尾 ,把f 或 fe变成 -ves 例词:beaf——beaves , life——lives
第三人称单数变化形式和名词变复数变化形式相同
收起
主要是两动词连用,加to,还有双宾语,一个指人,一个指物,指人的叫间接宾语,指物的叫直接宾语
