The guests would be arriving soon and Claire told Tony to go into another room.客人很快就要来了,克莱尔叫托尼去另一个间房.句中用到过去将来进行时,由"would +be + 动词的现在分词〞构成,表示在过去看来将来某一时间正在发生的动作.它常和表示过去将来的时间状语连用,但上下文清楚时,时间状语可省略.和将来进行时一样,它也常表计划中的事,不表意愿或打算.它还有一个特点,即常用在宾语从句<尤其是间接引语>中.例如：a. Mr. Smith never realized that some day he would be living in China.b. Mary told us that Jack would be coming next Saturday.[拓展]过去将来进行时有时也可用于其他从句中,如：I would pay the rest as I would be leaving Beijing. <用在状语从句中.>也可用在独立句中.如：The car started. EllenGreen would be driving off to the college.。
