and after / before that = after / before which
【典型例題1】
He was educated at a local grammar school, _______ he went on to
A. from which B. after that
C. after which D. from this
【解析】句意：他在當(dāng)?shù)匾凰姆▽W(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

He left his hometown 20 years ago and after that nothing was heard about him.
