第二家族：行为动词一般疑问句的构成 问句： Do your parents like English？ 肯答： Yes，they do. 否答： No，they don’t. 助动词 + 主语 + 动词原形 + 其它？ 肯定回答用“Yes, 主语+ do/does.” 否定回答用“No, 主语+do not/does not.” 助动词也常用缩写形式，主要有don’t，doesn’t 特别注意：对于第二家族一定要注意动词的还原， 因为时态与数的变化已经体现在助动词上了。 第二家族：含行为动词（或称为实义动词）一般疑问句的改写 秘诀：一加二改三问号　　一加：即在句首加助动词Do或Does；　　二改：1、把谓语动词改为原形； 2、改换主语称谓（同第一家组）；　　三问号：句末的句号改为问号。 We read English every morning. → Do you read English every morning? Tom’s father listens to English on the radio every evening . → Does Tom’s father listen to English on the radio every evening? 句型转换 1. Mr. Green comes from Shanghai. (改为一般疑问句) 2.
