题目内容

16．I was watching TV__________my brother was writing an e-mail at home at this time last night．（　　）

A．

as soon as

B．

after

C．

until

D．

while

分析昨天晚上这个时候，当我哥哥在家里写电子邮件的时候，我在看电视．

解答答案：D；
根据设空处前后的句子都用了过去进行时，可以推断本句的句意是"昨天晚上这个时候，当我哥哥在家里写电子邮件的时候，我在看电视．"，表示主句的动作和从句的动作同时发生且持续进行，用while引导时间状语从句，while"当…时"，通常与延续性动词连用，表示两个动作同步发生，故选D．

点评联系前后语境，在准确把握前后句关系的基础上，先推测出大体句意；再结合关键词利用其固定用法选出正确答案．
