③次数：一次once 两次twice①系动词be三变化，am , is , 还有are ，【一般现在时中，be动词只有am , is , 和are 三种形式。
】②I接am，you 接are，is连接他/她/它，【I和am连用，you和are连用he/she/it 和is 连用。
】③单数后面用is，复数后面都用are，【这里的单数主要指this/that/Tom/mymother/China等，复数主要指we/they/these/those/my parents等。
】④变疑问，be提前，句尾问号写周全，【肯定句变成一般疑问句时，把be提到句首，句尾的句号变问号就行。
】⑤变否定，真容易，be 和not是标记，【肯定句变成否定句时，只需把not放到be动词之后就行了。
】⑥应用时，要注意，缩略形式记心里，【be动词和很多词能构成缩写形式，这一点是需要记住的。
】⑦be词虽小作用大，初学英语全靠它。
