■after / before which 引導(dǎo)的定語從句

and after / before that = after / before which

【典型例題1】

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

【解析】句意：他在當(dāng)?shù)匾凰�文法學(xué)校上學(xué)，之后他便去了劍橋。after that意為“然后，之后”，但不能引導(dǎo)一個(gè)定語從句，因此B項(xiàng)也被排除；after which相當(dāng)于and after that，故此句可改寫為：

He was educated at a local grammar school, and after that he went on to Cambridge.
