(单选题)

He was offered a position at the local church school, ______ he went to the Cambridge.

A.after when

B.since which

C.after which

D. since when

参考答案：C

参考解析：

考查介词+关系代词的用法。句意：当地教会学校给他提供了一份工作，之后他去了剑桥大学。定语从句部分发生在“He was offered a position at the local church school”之后，故用after，指代前句整件事情，应用关系代词which。故选C。
