Tell the difference! 一般疑问句 一般疑问句是用提问的方式提供一些信息，要求对方用yes 或no 回答的一种疑问句。 答语中通常重复问句里的系动词be 、助动词或情态动词，完全否定时口语中通常使用缩 略形式(如 aren't 、doesn't 、can't) 。 例如： A:Is this your  brother?   B:Yes,it is./ No,it isn't. A:Can you speak English? B:Yes,I can./ NO,I can’t. A:Do you often play ping-pong together? B:Yes,we do./ No,we don't.  A:Do you play the piano? B:Yes,I do./ No,I don’t. 变成陈述句(注意人称） This is my brother. I can speak English. We often play ping-pong together. I play the piano. 当陈述句中有be 动词和情态动词，变成一般疑问句时，把be 动词和情态动词置于句首。 当陈述句中没有be动词和情态动词，有实义动词（意义完全，能独立作谓语）时，借助助动词 do /does 构成一般疑问句。注意：当主语是单数时，用does. Teng Fei:Hi,Peter!Come in.
