be动词用法口诀的意思***一定要学会画出关键词***
我(I)用am,你(you)用are, is连着他(he),她(she),它(it); 单数名词用is,复数名词全用are。 1.)变疑问,往前提,句末问号莫丢弃。 2.) 变否定,更容易, be后not莫忘记。 3.) 疑问否定任你变,句首大写莫迟疑。 例子 : 下面这些是固定用法: My parents are teachers. I have two new dresses. These are my shorts. Those are my shorts. This is my mother. That is my father . Jim and Lisa are good students.
注意: I am a student. 变为疑问句时应该用 Are you a student?
