Question

一道英语题，急啊！！

Peter and Mary seldom finish their work at school.(改为反意疑问句)
Peter and Mary seldom finish their work at school,______ _______?

请写出答案和解题思路，谢谢！！！

Answer 1

do they?
主语：Peter and Mary两个人，所以是复数。
seldom, hardly, never, 与not一样都是否定副词，所以前面的句子属于否定句。
这就是反意问句中的前否后肯。

Answer 2

do they

Answer 3

seldom有否定意味
finish ; Peter and Mary 主语复数用do
所以是 do they

Answer 4

do they

Answer 5

A
这里不是特指，就是一本书的意思，所以不能选D
useful前面的冠词应该用a。
