4个回答

  • (3)但如果主句的时态是过去时等等,疑问句应和主句的人称时态保持一致.

    had better或have

    陈述部分有had better,或其中的have表示完成时态时,疑问句应用hadn’t等开头:   You’d better get up early, hadn’t you?   其他情况句中有have时疑问句应用don't等开头   如have表示“有”的时候,有两种形式:(have 表示有 可用do或 have来改写)   -He has two sisters,doesn't he? =He has two sisters,hasn't he?   -He doesn't have any sisters,does he?
