Question

（2014届江西省重点中学盟校高三第二次联考英语试卷）27. 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

B

本题实际上考察的是固定句式：It is some time before…一段时间以后某事才发生；本句中的Two years passed before she was treated for breast cancer.相当于It was two years before she was treated for breast cancer.句义：与关心自己相比她更关心的是学生，那就是为什么2年以后她采取治疗乳腺癌。故B正确。
