.It is reported that two schools,_______fell into ruins in the earthquake, are being rebuilt and will be open next term.

A．they both

B．both of which

C．which both

D．both of them

答案

B

解析

考查非限制性定语从句。句意“据报道，两所学校在地震中称了废墟，它们正在被重建，下个学期投入使用。”题目所给范围是两者，故用both，意为“两者都”；根据逗号可知，是非限制性定语从句，排除A、D；both of which相当于and both of them。故选B。
