(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 /cant play soccer. |
