第一步,分析句子结构,这是一句由Or连接的并列复合句.Or表示否则.
第二步,理解句子意思.
Hurry up 赶快,
or 不然,
by the time 在……之前
we reach the box office, 我们到达售票室
all the tickets 所有的票
_____out. 卖光
连起来,句子的意思是说:
赶紧的,不然,在我们到达售票室之前,所有的票都卖光了.
这里需要我们判断 sell out 的时态.
说这句话时,是提醒对方赶快hurry up,因此到达售票室reach the box office这个动作是将来的,还未发生.而sell out 这个动作发生在reach the box office之前,表示“到达售票室之前,票就卖光了”,所以是将来的前面一段时间,也就是将来完成时态.选择D
选D. by the time +一般现在时表将来,主句要用将来时,by+时间需要用完成时,主语为物tickets 用被动。
总结:by the time +一般现在时,主句用将来完成时;
by the time +一般过去时,主句用过去完成时
选D
