B |
解析
试题分析:考查连词的用法,A. since自从;B. before在…之前;before主要引导时间状语从句,意为“先于”“…之后才”“(不多久)就…”。当主句是将来时时,从句谓语动词须用现在时;当主句是一般过去时或过去完成时时,从句常用过去时。before引导的时间状语从句不能用于否定式。C. after在…之后;D. until直到…,句子意思“在我们做最后决定之前我们需要一些证据和数据” 点评:连词是高考常考内容,判断从句中用哪个连词,需用记住连词的用法,在句中的作用,需要考生平时多练习。 即学即练:We hadn’t been out for long _________ she felt sick. A. as B. while C. after D. before 选D 句意:我们还没出去多久她就生病了。 |
