He was educated at a local grammar school, ________ he went on to Cambridge.

He was educated at a local grammar school, ________ he went on to Cambridge.

A.from which

B.after that

C.after which

D.from this

答案及解析： C

解析：

此题考查的是非限制性定语从句。先行词指的是前面a local school，故排除B、D。句意：他在当地的一家文法学校接受教育，之后去了剑桥。如选B，应改为and after that。
