英语一般现在时

一般现在时

第一节【知识梳理】

一、一般现在时的用法：

1、表达经常性或习惯性的动作。

2、表示现在的状态。

3、表示真理或客观事实。

例如：1、我们经常在操场上踢足球

We often play football on the playground.

2、他是一个学生。

He is a student.

3、地球绕着太阳转。

The earth goes round the sun.

二、一般现在时需要表示经常性的时间状语

例如：always、usually、often、sometimes、every day、

in the morning/afternoon/evening、on Sundays等。

频率副词：always usually often sometimes seldom never

总是通常经常有时很少从不

三、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. 我是一名学生。

??? I am 还可缩写成I'm。如：I'm David. 我是大卫。

am 与 not 不能缩写。如：I am not a bad boy.

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? 你是十二岁吗？

??? Tom and Lily are good friends. 汤姆和莉莉是好朋友。

??? They are at school.? 他们在学校。

are与主语还可缩写。如： We are= We're， They are =They're, You are

= You're。

而are与 not可缩写成aren't。如：They aren't students. 他们不是学生。

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. 我的妈妈是一名老师。

?? He is a student. 他是一名学生。

is也可与主语缩写,如: He is = 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。如:This isn't a book. 这不是一本书。

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。

如：It is a book. 变为：Is it a book?

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.

如：It is a book. 变为: It is not a book.

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(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）如：There is a book on the desk. have(has) 表示某人拥有某物如：My father has a car.
