will have done是将来完成时,将来完成时表示到将来某一时刻已完成的动作或状态。将来完成时由shall/will have加过去分词构成。
Or maybe you can, and already will have done so.
也许你可以,而且已经将要听到了。
We will have done the job ahead of time if it doesn't rain.
如果不下雨,我们定能提前完成这项工作。
Most of us will have done this at some point, many of us still do.
我们很多人都在某些情况下这么做过,很多人仍然在做。
Even if they prevail, however, Mr Perez's bill will have done some good.
然而,即便他们获得了胜利,佩雷斯的法案仍将带来一些益处。
将来完成时的句型
将来完成时的肯定句
句型:主语 + shall/will have + 过去分词…
将来完成时的肯定句由“助动词shall/will have + 过去分词…”构成:
I shall have done it by next week.我将于下周前做完它。
I shall have completed my report by Friday.到星期五我就会完成我的报告。
The snow will have disappeared before the end of February.积雪将于2月底之前融化。
将来完成时的否定句
句型:主语 + shall/will + not + have + 过去分词…
将来完成时的否定句是在助动词shall/will后加not,之后是“have + 过去分词”:
We have worked together for several years. She won't have forgot-ten me.我们在一起工作了几年,她大概不会不记得我。
将来完成时的一般疑问句
句型: Shall/Will + 主语 + have + 过去分词…?
回答方式:Yes,主语 + shall/will.
No,主语 + shall/will + not.
将来完成时的疑问句是将助动词shall/will置于主语之前(大写shall/will的第一个字母),在句尾加问号;这种语序是倒装语序:
Will you have done it all by 10:30pm? —No,I won't have done it by then.
你能在晚10点半之前把它全部做完吗? ——不,我那时还做不完。
Will you have finished reading the book by Friday? —Yes,I'll have finished reading the book by Tuesday.你会在星期五之前看完这本书吗? ——是,我最迟在星期二就看完这本书了。
将来完成时的特殊疑问句
句型:疑问代词/疑问副词 + shall/will + 主语 + have + 过去分词…?
将来完成时的特殊疑问句是将疑问代词/疑问副词置于助动词shall/will之前(shall/will的第一个字母无需大写),和一般疑问句差不多;这种语序是倒装语序。就主语提问时,将疑问代词或带有疑问限定词的名词词组置于助动词shall/will之前,在句尾加问号;这种语序是陈述句语序:
How many words shall we have learned by the end of the term?
到本学期末我们可能学了多少词汇?
