He is Brown. =He's Brown. They are Jane and Linda. =They're Jane and Linda. 2. be动词的否定式是在be后面加not。（表格为一般现在时态中，be动词的否定形式） 3.be动词的一般疑问句的结构为：be(am/is/are)+主语+……？ 肯定回答为：Yes, 主语+be(am/is/are). 否定回答为：No, 主语+be(am/is/are)+not. 例：-Are they your classmates? -Yes, they are. / No, they aren't/are not. 注意：第一人称I变一般疑问句时，需转换成第二人称you。 二、实意动词的一般现在时 1.肯定形式： 当句子的主语是第三人称单数形式时，谓语动词也要用第三人称单数形式。其变化规律如下： 例：He gets up at six every day. 2.否定形式： 3.一般疑问及回答： 一般将来时 1.用be going to do表示将来： 一是表示“意图”，即打算在最近的将来或将来进行某事。 Are you going to post that letter?
