be动词的用法

am is are

一．be动词的种类

be动词包括“am”, “is”, “are”及其变形was和were，另“am”, “is”, “are”的原形是be。

第一人称单数( I )配合am来用。

I am ten years old.

I am a student.

I am a boy.

第二人称(You)配合are使用。

句型解析：Y ou are+…例：You are my good friend.

You are a good person.

You are beautiful.

第三人称单数(He or She or It)配合is使用。

句型解析：She(He, It) is +……例：She is a good girl.

She is so cute.

She is a teacher.

人称复数(we /you/they)配合are使用。

句型解析：We (You, They) are +……例：We are in Class 5,Grade 7.

They are my friends.

You are good students.

综合解析:

当使用be动词的时候，前面请先加上第几人称。

be动词前面的人称，是不可随意替换的。

例如：I am, You are, She is，并不会出现I is, Y ou am, She are 这样的情形。

Be的用法口诀

I用am；you,we ，they 都用are, is连着he，she，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

注：

I’m=I am 我是

she’s=she is 她是

He’s=he is 他是

It’s=it is 它是

you’re =you are 你是（复数形式）

they’re=they are 他（她；它）们是

isn’t=is not 不是（单数形式）

he’s not =he is not=he isn’t他不是

含be动词的一般疑问句，否定句，以及回答

1.以be动词开头的一般疑问句的结构为：be动词+主语+表语

名词、数词等）。

例如：—Is this your pencil？这是你的铅笔吗？

—Yes，it is. / No，it isn’t.是的，是我的。/ 不，不是我的。

2.将肯定的陈述句变为否定的陈述句的方法：1找到be动词，在be 动词之后加上not就可以了，其他的不变。

例如：（肯定的陈述句）This is my bike.

（否定的陈述句）This is not my bike.---- This isn`t my bike.

3. 将陈述句变为一般疑问句时，应将be动词移到主语之前并大写其首字母，句末标点用问号，其他句子成分照搬。（注意，i 要变为you，my要变成变your，其他人称不变）。

例如：This is my bike. 这是我的自行车。

→Is this your bike？这是你的自行车吗？

4. 一般疑问句通常用yes或no来回答。

例如：—Are you Gina？你是吉娜吗？

—Yes，I am. / No，I’m not.是的，我是。/ 不，我不是。

有些一般疑问句也可以用其他形式来回答。例如：

—Is this Gina’s book？这是吉娜的书吗？

—Sorry，I don’t know.对不起，我不知道。
