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, You 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
用动词am, is, are填空(请注意大小写)

1. Where ______ Ann? She ______ here.
2. How old ______ you? I ______ thirteen.
3. ______ you Mr Read? Yes, I ______.
4. What ______ your name? My name ______
