1. be动词的概念：be动词是系动词的一种，是与一般动词相区别的概念。

一般动词表示具体的动作。

而be动词不是动作，它通常与名词、形容词或其它词类一起表示主语的性质、状态、身份、特点等等。

一般动词很多，如：walk、read、stand等等，而be动词只有一个，那就是be，所以它称为be动词。

be 动词在不同的句子中有不同的中文意义，有时甚至不用翻译其意义。

be动词有不同的形式，如：现在式有am, are, is 三种，过去式有was和were两种，过去分词只有been一种形式。

2. be动词的现在式用法：be动词的现在式有am, are, is三种，具体用哪一种，必须由主语的人称和数决定。

如下表所示：例句：I am a student. 我是一名学生。

We are all here. 我们大家都在这儿。

You are so beautiful. 你是那么漂亮。

He is my English teacher. 他是我的英语老师。

Is she nine years old？她是九岁吗？My name is Mary. 我的名字叫玛丽。

It is sunny today. 今天的天气晴朗。

Tom and his friends are in the park. 汤姆和他的朋友们都在公园里。

3. be动词的过去式用法：be动词的过去式是：was和were, 这两种形式与现在式用法没有多大区别，作谓语时用哪一种，还是由主语的人称和数决定。

如下表：否定句：主语+be动词+not……如：My father is not a teacher. 缩写：My father isn’t a teacher.We are not at home. 缩写：We aren’t at home.疑问句：be动词+主语……如：一般疑问句及其回答：Are you a student? 回答：Yes, I am. No, I am not.注意：含be动词的一般疑问句回答用Yes或No. 其结构是：Yes, + 主语 + be动词 / No, + 主语 + be动词 + not.特殊疑问句：What is your name?How are you?Where is my pencil-box?4. There be句型：there be句型是含有be动词的一个重要句型。

其结构如下：there + be动词 + 名词 + 地点状语There is a school there. 那里有一个学校。
