问题 Her brother______while he______ his horse and had his leg broken.

选项 A、fell; ride
B、fell; was riding
C、had fallen; was riding

答案B

解析 首先分析句子结构:and 前是一个主从复合句,其中while 引导时间状语;and 是并列连词,它连接的两个句子一般时态与语态都相同。由于and 后用的是一般过去时,所以其前一句的主句也应用—般过去时,因此排除了[C]项,而由while 引导的时间状语从句中一般用进行时态,表示“在……的同时”,又因主句用一般过去时,故从句中应用过去进行时态。
