A. haven't they
B. didn't they
C. have they
D. did they
题目解答
答案
C. have they
解析
本题考查反义疑问句(附加疑问句)的构成规则。关键点在于:
- 陈述句与疑问句的否定性相反:若陈述句为否定形式(如含
never),疑问部分需用肯定形式; - 时态和助动词一致:疑问部分的助动词需与陈述句中的助动词保持一致(本题中为现在完成时的
have)。
步骤解析
-
判断陈述句的否定性
原句They've never been there中,never表示否定,因此陈述句为否定形式。 -
确定疑问部分的否定性
根据反义疑问句规则,陈述句为否定时,疑问部分需用肯定形式。 -
匹配时态和助动词
陈述句使用现在完成时(have been),因此疑问部分需用相同的助动词have,且主语为they,故疑问部分为have they。 -
排除干扰项
- A. haven't they:与陈述句同为否定,错误;
- B. didn't they、D. did they:时态错误(一般过去时);
- C. have they:时态、否定性均正确。
