Question

【题目】She cared more about her students than her own health. That’s why two years passed _____ she was treated for breast cancer.

A. since

B. before

C. after

D. until

Answer 1

【答案】B

【解析】考查时间状语从句中连词的用法。句意：她关心学生多于自己的健康，这就是为什么两年过去了她才治疗她的乳腺癌。因为在治疗乳腺癌之前过去的两年，所以用before，可以翻译成“才/就”，since“自从”，after“在…后面”，until直到，所以选B。
