高考英语时态题精讲之将来完成时
英语动词时态范畴在英语中起重要作用,也是英语教学的中心任务之一。以下是学习啦小编为您整理的高考英语时态题精讲之将来完成时,仅供参考!
将来完成时的基本用法
表示到将来某个时间为止势必会完成或预计要完成的动作,由“will [shall]+have+过去分词”构成:
He will have arrived by now. 他现在应当已经到了。
He will have gone back to England.他想必回英国去了。
When we get there,she’ll have gone to work. 我们到那里时她会已上班去了。
On Monday he’ll have been in Britain for three years. 到星期一,他在英国就满三年了。
1. 表示将来完成
即表示到将来某个时间为止势必会完成或预计要完成的动作。如:
Maybe by then you will have changed your mind. 也许到时候你已经改变主意了。
“You'll have finished by tomorrow.” “I wish!” “你到明天就完成了。”“但愿如此! ”
I hope I'll have finished the work by the end of the month. 我希望我这个月底能完成工作。
Demand for cars in the developed world will have reached saturation point within 20 years. 不出20年,已发展国家的汽车需求将达到饱和。
Planning so far ahead makes no sense—so many things will have changed by next year. 提前这么久就计划并不明智——到明年,许多事情都会发生变化。
2. 表示动词的持续
即表示某种状况将一直持续到说话人所提及某一将来时间。如:
We will have been married a year on June 25th 到6月25日我们俩结婚就满1年了。
By this time next week, I will have worked for this company for 24 years. 到下星期此刻,我已经为该公司干了24年了。
3. 表示推测
即表示根据某情况作出的推测。如:
That will have been Roland. He said he'd be back at 7. 准是罗兰,他说他7点钟回来。
There will have been a definite result before Friday. 星期五以前将肯定会有结果。
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。
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. 我完成工作后就同你去。
