Question

【題目】It was nearly a week _______ the rescue team located the crashed plane.

A. since B. before

C. until D. after

Answer 1

【答案】B

【解析】

考查時(shí)間狀語(yǔ)從句。A. since自從；B. before在……之前；C. until直到；D. after在……之后。句意：救援隊(duì)花了將近一周的時(shí)間才找到墜毀的飛機(jī)。It is/was+一段時(shí)間+before表示“距某發(fā)生有……的時(shí)間”，故B項(xiàng)正確。
