be动词的用法
be动词有三种形式：am, is, are. 其中be是原形，am和is是单数，are 是复数
be 动词的用法
be动词的用法口诀现在时：I am , You are , He / She / It is 。
过去时：I / She / He was。
You / They were。
be 动词+动词（不定式，动名词ing，分词）。
例子： I am good. He is good. You are good.I was doing my homework.They were to go swimming when I saw them.The book was given by my sister.Be 是原形，摇身一变成is, am, are。
下面介绍一则口诀，帮你熟记“动词be的构成”：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。
变否定，更容易，be后not加上去。
变疑问，往前提，句末问号莫丢弃。
还有一条须注意，句首大写莫忘记。
改一般疑问句口诀一般疑问句不可怕，先找be动与情动；若有be动或情动，只将be等放句首；若有第一人称词，务必改为二人称；其它部分不用改，注意句末用问号。
若无be动或情动，助动do/does放句首；句中需跟原动词，其他部分同样变。
解释：① be动词：am/is/are；②情态动词：can/may/must；③人称变化：I→you；my→your；we→you；our→your；am→are；does→Does…do; has→Does…have; likes→Does… like.I’m in Class Three, Grade Seven.→Are you in Class Three, Grade Seven ?He watch es TV every day.→Does he watch TV every day?改为否定句口诀变否定很容易，先找be动与情动；若有be动或情动，直加not即可以；若有some变any，其他部分不用动；若无be动或情动，需加don’t、doesn’t；再跟原动才可以，其他部分不解释：原动就是指动词原形，如does→doesn’t do; has→doesn’t have; likes→doesn’t like，此时的do/have/like即原形动词。
