一般现在时知识点总结

一般现在时知识点总结

一、本次知识点归纳：

表达经常性或习惯性的动作、状态、表示真理或客观事实。

二、重要知识点提示：

一般现在时需要表示经常性的时间状语

例如：always、usually、often、sometimes、everyday、in the morning/afternoon/evening 、on Sundays等。

be动词的一般现在时有三种形式，即：am, is, are（翻译为“是”）

1. 如果主语是第一人称I（我）时，be动词用am。如：I am a student.

I am 还可缩写成I'm am 与not 不能缩写。

2.如果主语是you （你，你们）, they （他们，它们，她们）或名词复数（两个以上的人或物）时，be动词必须用are

如：Are you twelve?

are与主语还可缩写。如：We're，They're, You're。

而are与not可缩写成aren't

3.如果主语是单数名词、不可数名词或第三人称单数代词（he, she, it）时，be动词用is。如:My mother is a teacher.

is也可与主语缩写,如: He's, My mother is = My mother's等。但是This is不可缩写。而is与not 可缩写成isn't

4.句中含有be动词的陈述句变一般疑问句。

把be动词提到句首，be动词要变大写。注意第一人称变第二人称。回答时用yes或no表示，结构：Yes, 主语+be动词，No，主语+be动词+not。

5. 句中含有be动词的肯定陈述句变否定句。

先找肯定陈述句中的be动词，在be动词后加not.

根据以上叙述我们可以把动词的用法以口诀的形式表述出来：

我用am，你用are，is跟着他(he)，她(she)，它(it)；

单数名词用is，复数名词全用are。变疑问，往前提，句末问号莫丢弃。变否定，更容易，be后not莫忘记。

疑问否定任你变，句首大写莫迟疑。

三、There be句型

1、There be 的固定句型：There be + 某物/某人+ 介词+ 某地

表示：在某地有某物（或人）

2、在there be 句型中，主语是单数，be 动词用is ; 主语是复数，be 动词用are ;

如有几件物品，be 动词根据最靠近be 动词的那个名词决定。

3、there be 句型的否定句在be 动词后加not , 一般疑问句把be 动词调到句首。

4、there be句型与have(has) 的区别：

there be 表示在某地有某物（或人）have(has) 表示某人拥有某物
