将来完成时常用于表示动作,状态或事件等会在将来的某个时刻完成,完毕,或结束。
谓语动词表现将来完成时的构成形式是:
shall(第一人称)/will(第二、三人称)+have+过去分词(done)。
当动词be作谓语时,表现将来完成时的形式为 shall/will have + been
注意:根据不同的表达意图或是语境需要,可以使用其它情态助动词来代替will,比如:may,
should等。
具体示例如下:
Many
people are
hoping that the
bushfire will have
finished before summer comes.
许多人都希望这场森林大火能在夏天来临前结束。

roommates will have
moved out before the end of June.

①by(the time/the end of)+表示将来时间的短语和句子;
②before(the end of)+表示将来时间的词语或句子;
③when,
after等加上表示将来动作的句子等。
