问题 Although some countries have taken action to solve the shortage of water, it may be sometime __________ the situation improves.
选项 A.before

B.when

C.since

D.until
答案A
解析考查连词。句意为“尽管一些国家已经采取措施解决水资源短缺的问题，但是可能还要有一段时间．情况才会好转”，before“在……之前”，when“当……时候”，since“自从”，until“直到”。固定句型itmay／willbe+时间段+before从句表示“还要过多久才……”．故选A。
