一般现在时 (The Simple Present Tense)
一般现在时：表示经常、反复发生的动作，经常存在的状态或者习惯性动作的一种时间状态。
改改句子形式吧，否定及疑问句是：This is her handbag.This is nt her handbag.Is this her handbag?She can type this letter.She can nt type this letter.Can she type this letter?
否定句和疑问的构成：如果是be动词，就直接在be后加nt构成否定式；将be提至主语前变一般疑问句。如果是情态动词，就直接在情态动词后加nt构成否定式；将can提至主语前变成一般疑问句。
1.It is a red is is my name is Mary.5.I am Jenny.
1.be 动词的一般现在时的句式： 肯定句：主语+be+表语(n., adj.等) e.g. He is a wrker. Yu are thirteen. They are in the classrm. 否定句：主语+be+ nt+表语 e.g. He is nt a wrker. Yu aren’t thirteen. They aren’t in the classrm. 一般疑问句：Be+主语+表语? e.g. Is he a wrker? Yes, he is./N, he isn’t. Are yu thirteen? Are they in the classrm? Yes, they are. N, they aren’t.
Be的用法口诀   I用am； yu 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nt莫忘记。 疑问否定任你变，句首大写莫迟疑.
