The government has taken some measures to solve the shortage of electricity, but it may be some time ____________ the situation improves.
A.sinceB.whenC.unlessD.before
D

试题分析:考察固定句式。固定句式:It be 一段时间 before…一段时间以后某事才发生;如果before后面使用一般现在时,前面的主语使用将来时;如果before后面使用一般过去时,前面也使用一般过去时。句意:政府已经采取措施来解决电量短缺的问题,但是也许要一段时间以情况才会有所改善。故D正确。
点评:固定句式的考察是时态以及连词考察的重点,本句中的固定句式:It be 一段时间 before…一段时间以后某事才发生;如果before后面使用一般现在时,前面的主语使用将来时;如果before后面使用一般过去时,前面也使用一般过去时。
