你发现了什么？
当使用be动词的时候，前面请先加上第人
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, You am, She are 这样的情形。
Be的用法口诀 I用am；you（we ，they ） 用are,
is连着他、她、它（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
1.我(I)用am，你(you)用are， is连着他(he)，她(she)，它(it)；
这些是固定用法：
I am Tom (你不能说 I is Tom)
You are Jane.
She is a girl.
We are friends.
2.单数名词用is，复数名词全用are。
(主语个数是一个时，谓语用单数is，主语个数为2个或以上，谓语用复数are.)
The flower is beautiful.(一朵花）
The flowers are beautiful.（很多花）
3.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。
She is twelve years old.
变为：Is she twelve years old
She is twelve years old.
变为: She is not twelve years old.(否定句）
4.疑问否定任你变，句首大写莫迟
如：It is a book.变为：Is it a book (疑问句）
