试题分析:句意:该领域的研究将用掉Luffy和Steven约两个星期的时间;很长时间之后, 我们才能再次会面。1)It is a long time sine…表示自从.. 已经很久了。主句多用一般现在时态,从句用过去时态。 从句的动词若为瞬间动词,时间从动作的开始算起,从句的动词若为延续性动词,时间从动作的结束算起。It is 3 years since he left Shanghai. =" It" is 3 years since he was in Shanghai.他离开上海已经3年了。2)It will be long before…表示“很久以后将…”It will be long before the film is on。3)It won’t be long before … 表示“不久以后将…”It won’t be long before the film is on。故选C。 考点: 考查状语从句的用法。 |
