几道英语选择题,关于反意疑问句的..

A do I B don't I C will he D won't he
Peter is a man of few words,____he?
A is B isn't C does D doesn't
This book cost her twenty yuan,___?
A does it B doesn't it C did it D didn't it
第一题答案是C,可是为什么不是A啊..第二题答案是B为什么不是A?
第三题答案是D,为什么不是B?

Answer 1

第一题答案是C的原因：反意疑问句中,以第一人称(I / We)+ think / believe / know / imagine / suppose / guess / expect / etc.开头的主从复合句,其疑问部分的主谓语应与从句的主谓语保持一致.don\'t在这里是否定前移,其实是从句是否定,所以是 C will he
第二题答案是B的原因:因为few这里是修饰word的,而不是主句中的,所以这句话还是肯定,即选B isn\'t
第三题答案是D的原因:注意cost是原形,可book是单三,应该是costs啊.不对,因为这里cost是cost的过去时,所以选D didn\'t it
