小升初英语语法解析+常见知识点总结

  最新小升初英语最常见的知识点总结

1、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。

,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?

  小升初英语语法解析

句首为否定或半否定的词语,如no, not, never, seldom, little, hardly, at no time, in no way, not until… 等。

Never have I seen such a performance.

Nowhere will you find the answer to this question.

Not until the child fell asleep did the mother leave the room.

当Not until引出主从复合句,主句倒装,从句不倒装。

注意: 如否定词不在句首不倒装。

I have never seen such a performance.

The mother didn't leave the room until the child fell asleep.

典型例题

1)Why can't I smoke here?

At no time___ in the meeting-room

A. is smoking ing is permitted

C. smoking is it smoking permit

答案A. 这是一个倒装问题。当否定词语置于句首以表示强调时,其句中的主谓须用倒装结构。 这些否定词包括no, little, hardly, seldom, never, not only, not until等。本题的正常语序是 Smoking is permitted in the meeting-room at no time.

2) Not until the early years of the 19th century ___ what heat is.

A. man did know B. man know C. didn't man know D. did man know

答案D. 看到Not until…的句型,我们知道为一倒装句,答案在C,D 中选一个。
