Question

（2014屆江西省重點中學盟校高三第二次聯考英語試卷）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

本題實際上考察的是固定句式：It is some time before…一段時間以后某事才發生；本句中的Two years passed before she was treated for breast cancer.相當于It was two years before she was treated for breast cancer.句義：與關心自己相比她更關心的是學生，那就是為什么2年以后她采取治療乳腺癌。故B正確。
