Question

It is reported that two schools,____ are being built in my hometown,will open next year.

A.they both                                                     B.which both

C.both of them                                                 D.both of which

Answer 1

D

解析:

both of which引导非限制性定语从句，which指代先行词schools,作of的宾语。they both和both of them都不能引导定语从句，所以是错误的。which both中的which不能修饰both，所以也是错误的。
