过去将来完成时

过去将来完成时表示在过去将来某一时间以前发生的动作，并往往会对过去将来某一时间产生影响。它常和表过去将来的时间状语连用。如：

The party would have arrived by four o’clock. 这一行人将于4时前到达。

The day was drawing near when we would have completed the reservoir. 我们水库完工的日子不远了。

He said he would have done with my camera by the end of next month. 他说到下月底就不用我的照相机了。

[注]在下面的句子中，would是情态动词，有“大概”或“料想是”等含义，并无“将要”的意思：

①I want you thinking of food and wine, because these last years would have been miserable for you. 我要你只想吃喝，因为最近几年你的生活想是够苦的。

②That would have been rather difficult. 那大概是相当不容易的吧。
