It won’t be too long before we_____a way to smooth away these difficulties.
A.work outB.willworkout
C.had worked outD.are working out
A

试题分析:句意:过不了多久我们将能够找到解决这些困难的的方法。这里是句式it will not +some time+before过不了多久就会怎样。before引导的时间状语从句不能用将来时,因为主句用的是一般将来时,从句不可能用过去完成时,故选A。
点评:本题难度适中。动词时态也是高中阶段的重难点之一,需要考生能够理解句意进而对动词的时态做出正确的判断。这里考生容易误选B。
即学即练:I wasn’t sure if he was really interested or if he    polite.
A.was just being      B.will just be    C.had just been       D.would just be
解析:句意:“我不能确信他是真正感兴趣呢还是仅仅为了表示礼貌。”句前wasn’t sure表明说话的起点是过去时,was really interested和was just being polite都是相一致的过去时。
