將來(lái)完成時(shí)與將來(lái)完成進(jìn)行時(shí)的區(qū)別
將來(lái)完成進(jìn)行時(shí)和將來(lái)完成時(shí)的區(qū)別
將來(lái)完成時(shí)的結(jié)構(gòu)是:will+have+過(guò)去分詞;而將來(lái)完成進(jìn)行時(shí)的結(jié)構(gòu)是:will+have+been+現(xiàn)在分詞,二者在用法上有所區(qū)別,今天,小編就來(lái)介紹一下具體有哪幾點(diǎn):
1、將來(lái)完成進(jìn)行時(shí)強(qiáng)調(diào)動(dòng)作過(guò)程在另一動(dòng)詞之前的長(zhǎng)度。而將來(lái)完成時(shí)更強(qiáng)調(diào)在另一件事前一個(gè)動(dòng)作的完成。
如:
By the time John retires, James will have been practicing for 10 years.
與這個(gè)句子有所區(qū)別:
? ? ? Before the time John retires, James would have retired.
2、動(dòng)作本身就是連續(xù)的:
By the end of the month he will have been living/working/studying here for ten years.
與這個(gè)句子有所區(qū)別:
? ? ?By the end of the month, he will have worked for ten years.
3、一種經(jīng)常進(jìn)行的動(dòng)作被表示為連續(xù)的動(dòng)作:
By the end of this month he will have been training horses/climbing mountains for twenty years.
但是如果提到所馴馬匹或所攀登的山峰的數(shù)目,或用任何方式把動(dòng)作分割為一次又一次的動(dòng)作,就必須用將來(lái)完成時(shí):
By the end of the month he will have trained 600 horses/climbed 50 mountains.
