be动词的用法及练习

初一be动词练习题无答案

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:

例句:

I was a student last year, but now I am a teacher.

去年我是一名学生，但现在我是一名老师。

We were all very hap py at Tom’s birthday yesterday.

昨天在汤姆的生日会上我们大家都很开心。

You were only nine years old when I went to the university. 当我上大学时你才九岁。

He was often late for his class when he was a student.

当他是学生的时候，他老是上课迟到。

She was very sorry for that.

她为那件事感到很抱歉。

Tom and his friends were playing football when I saw them. 当我见到他们的时候，汤姆和他的朋友们正在踢足球。

4. be动词的句型如下:

肯定句:主语+be动词……

如:Mary is a student.

We are students.

I am a teacher.

Jack was born in 1989.

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.

It is not my book. 缩写:It isn’t my book.

I am not a teacher. 注意:现代英语中am not一般不用缩写形式。

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.

Am I right? 回答:Yes, you are. No, you are not.

Is he your friend? 回答:Yes, he is. No, he is not. )

Are they on the chair? 回答:Yes, they are. No, they are 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?

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。

在这个句型中a school是真正的主语，be动词的形式由它决定。当这个名词是单数时，be 动词是is或was, 当这个名词是复数时，be动词用are或were。如:

There are many students in the classroom. 在教室里有许多学生

There was an accident in the street last night.

昨晚这街上有个车祸。

There were lots of people in the room when I got in.

当我进去的时候，屋里有很多人。there be句型的一般

疑问句是将be动词提前，否定句也是将be动词后面加上not, 如:

Is there any water in the bottle? 瓶子里有一些水吗,

Are there any students in the room? 房间里有学生吗,

There isn’t any water in the bottle. 瓶子里没有水。

There aren’t any students in the room. 房间里没有任何学生。
