《2026年全效学习中考学练测英语外研版》

I was walking in the street ______（while/when）someone patted me on the shoulder.
【解析】when既可指某时刻，也可指某一段时间；主句和从句的动作可以同时发生，也可以先后发生。本句中应选择when，相当于and at this time，可以译为“这时；就在这个时候”。故填入when。
【归纳总结】while只能表示一段时间，不能表示某时刻，强调主句和从句的动作是同时发生的，从句的谓语动词必须用延续性动词。when既可指某时刻，也可指某一段时间，主句和从句的动作可以同时发生，也可以先后发生。
