She has a pen. 肯定句： I don’t have a pen. She doesn’t have a pen. 否定句： 动词原形 动词三单形式 助动词do、does 后的动词要用原形。 当主语是第三人称单数时，助动词要用does / doesn’t. Tip: She has two ping-pong balls. He has a baseball. I have a soccer ball. They have a volleyball. we have a volleyball. She doesn’t have two ping-pong balls. He doesn’t have a baseball. I don’t have a soccer ball. They don’t have a volleyball. we don’t have a volleyball. 实义动词变否定，动词前面don’t, doesn’t 添， 动词变原别忘记，你用don’t，我用don’t， 你们、我们、他们，都用don’t, he,she,it 要用doesn’t，主语三单用doesn’t. 有实义动词的句子变为否定句口诀： I have a pen. She has a pen. 肯定句： 一般疑问句： 一看：看动词 （动词是be动词就提前，是实义动词就借助助动词do/does） Do Does 二变：变大小写，句号变问号。 I have a pen she has a pen have a pen you have a pen 三检查：检查实义动词是否为原形，句子是否正确。 She has two ping-pong balls. He has a baseball. I have a soccer ball. They have a volleyball. we have a volleyball. Does she have two ping-pong balls Does he have a baseball Do you have a soccer ball D ... ...
