现在完成时、过去完成时与将来完成的 区别
现在完成时以现在时间为参照点，表示在“现在”以前 完成的动作或持续到“现在”的状态，过去完成时则以 过去时间为参照点，表示在“过去”某一时间以前发生 的动作或持续到“过去”某一时间的状态，将来完成时 则以将来时间为参照点，表示在“将来”某一时间为止 已经完成的动作或持续到“将来”某一时间的状态： He has finished writing his novel. 他已写完了他的小说。 He had finished writing his novel by the end of last year. 去年年底他就写完他的小说。 He will have finished writing his novel by the end of next year. 到明年年底他就会写完他的小说了。

将来完成时的用法
1表示在将来某一时间之前已完成的动作， 并往往对将来某一时间产生影响。 We shall have learned 12 units by the end of this term. 到这个学期末，我们将学完12个单元。 By the time you get home I will have cleaned the house from top to bottom. 你到家之前我将把房子彻底打扫一遍。
与一般现在时代替一般将来时一样，在表示时间或者条件的状语从句，通 常要用现在完成时来表示将来完成时，而不能直接使用将来完成时：
I will go with you when I have finished my work. 等我完成工作之后我就同你去。 若不强调动作的完成(且不致于引起歧义)， 有时也可用一般现在时： I will go with you when I finish my work. 我完成工作பைடு நூலகம்就同你去。
。例如： ① By the year 2050, scientists probably will have discovered a cure for cancer. 到2050年，科学家们可能已经找到了治愈癌 症的方法。 ② By the time you arrive in London, we will have been staying in Europe for two weeks. 等你到达伦敦的时候，我们已经在欧洲呆了 两星期了。
将来完成时
将来完成时用来表示在将来某一时间以前 已经完成或一直持续的动作经常与 before+将来时间或by+将来时间连用，也 可与before或by the time引导的现在时的 从句连用。
将来完成时的构成
将来完成时的构成是由"shall/will + have + 过去分词"构成的。 Before long he will have forgotten all about the matter. 不久他就会全然忘记这件事的。
