问题 ______ the book again, she discovered that she had missed a lot in her first reading.
选项 A、While reading
B、When read
C、As reading
D、In reading
答案 A
解析 本题测试while和when的区别。when和while都有“当……时候”的意思。when既可表示某一时间点，也可以表示某一时间段。在when引导的时间状语从句中，其谓语动词可以是延续性的，也可以是非延续性的；可与主句中的谓语动词同时发生，也可在其后发生。例如：I was just reading a book when she came Into my room．(她走进我的房间时，我正在看书。)而while只能表示某一时间段，不能表示某一时间点。在while引导的时间状语从句中，其谓语动词只能是延续性的，而且也只能与主句中的谓语动词同时发生或存在。例如：You can’t do your homework while you’re watching TV．(你不能一边看电视一边做家庭作业。)另外，when和while的区别还在于：while引导的时间状语从句多用进行时态，而when引导的时间状语从句多用一般时态。例如：While they were talking, the bell rang．(正在他们谈话的时候，上课铃响了。)I was doing my homework when my mother came back home yesterday evening．(昨天晚上妈妈回家的时候，我正在做家庭作业。)本句的意思是：“再读这本书时，她发现在她第一次阅读时漏掉了许多东西。”
