第二人称you+are; 一人称复数we+are； 三人称复数they+are 其他复数名词+are (注意：第二人称单复数同形，都为you) 例：You are my good friend. We are in the same class. They are on the road. The books are on the desk. (3) is

You are…= You are Are Are not Yes,you are. you’re… not…=You you…? you. ..? aren’t… =Aren’t No,you are you…? not.

Am I a Chniese? 回答： 肯定：Yes, you are. 否定： No, you aren’t.
Is the cat fat? 回答：肯定：Yes, it is. 否定： No, it isn’t. 注意：在一般疑问回答中，肯定回答除I’m不可简写,否定回答均可简写。
另：特殊疑问句中：where\\how\\who\\what\\why+be动词+人称代词或名词？
例：What is your name? My name is GaoBuHan. Where are you? I’m in the classroom. 3．总结：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 。
