am is are
一.be动词的种类

第一人称单数( I )配合am来用。

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。
