初中英语时态知识点：一般现在时的句子转换

（1）变一般疑问句：当句子中有be动词或情态动词时，则把be动词或情态动词(can,could等)提到主语的前面，

（口诀：一调二变三问号）;

（2）变否定句：在be动词或情态动词后面直接加not变成否定句. (be后not莫忘记)

例：①陈述句：She is my sister..

疑问句 Is she your sister? Yes, I am./ No, Im not.

否定句 She is not my sister.

②陈述句：I can play soccer.

疑问句 Can you play soccer? Yes,Ican./ No, I cant.

否定句 I can not /can play soccer.
