Question

--Could you tell me__________? --Yes. They_________ to the reading room.

A.where are the twins, have been B.where the twins are, have gone

C.where were the twins, have been

Answer

B

【解析】

句意：-你能告诉我这对双胞胎去哪里了吗？-好的，他们去了阅览室。where are the twins双胞胎在哪里；where the twins are双胞胎在哪里；where were the twins双胞胎在哪里，过去时态；have been去过某地；have gone去了某地。第一句话考查宾语从句，从句中应用陈述语序；根据句意第二句话表示“去了某地，还没有回来”，故应选B。
