题目内容
17．The woman didn't go to bed she finished all the housework．（ ）| A． | when | B． | until | C． | before | D． | while |
分析 那个妇女直到干完了所有的家务活才去睡觉．
解答 答案：B．
联系语境并根据前后句子的对比，可知句意是：那个妇女直到干完了所有的家务活才去睡觉；由于主句中的谓语动词是非延续性的动词，根据句意结合关键词 didn't，可以判断出此句应用固定表达not…until来完成，意为"直到…才…"引导一个时间状语从句．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．
