题目内容

11．________John was taking photos，Mary bought a drink．（　　）

A．

When

B．

While

C．

Although

D．

Unless

分析当约翰在拍照的时候，Mary去买了饮料．

解答答案：B；
根据设空处的句子用了过去进行时，可以推断本句的句意是"当约翰在拍照的时候，Mary去买了饮料．"，表示主句的动作发生在在从句动作持续进行的过程中，所以用while引导该时间状语从句，while"当…时"，通常与延续性动词连用，且用于进行时中，故选B．

点评本题主要考查连词的用法，连词在句子中主要起联系上下文的作用，他们之间的区别就是表示逻辑关系的不同，所以在解题时先要理解上下文含义，然后根据上下文逻辑关系选择合适的连词．连词的用法都比较多，语义之间还有交叉，熟记其基本应用规则，了解其区别，注意固定搭配对象，是做好此类题型的关键．
