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。

2.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?

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 permittedB.smoking is permitted

C. smoking is it permittedD.does 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。
