2017考研英語(yǔ):掌握16個(gè)動(dòng)詞時(shí)態(tài)的形式和用法(4)
考研英語(yǔ)中對(duì)動(dòng)詞語(yǔ)法的考察是比較常見的,所以考生對(duì)于動(dòng)詞的概念、形式和用法都必須熟練掌握,下面為大家做了詳細(xì)總結(jié),16考生注意理解。
4.完成進(jìn)行時(shí)態(tài)
毫無(wú)疑問(wèn),完成進(jìn)行時(shí)態(tài)對(duì)于大部分同學(xué)來(lái)說(shuō)都比較陌生。其含義為一件事情從過(guò)去到現(xiàn)在或離現(xiàn)在不遠(yuǎn)的一段時(shí)間內(nèi)完成的事情,并且會(huì)繼續(xù)進(jìn)行下去。(在某些句子中,從上下文可以看出,動(dòng)作已經(jīng)完成,不會(huì)繼續(xù)下去)
從形式上,完成進(jìn)行時(shí)仍然符合我們前面所用的方法,用“完成”(have done)+“進(jìn)行”(be doing)。但是,這里在得出結(jié)論的時(shí)候需要特別注意,將be doing代入完成時(shí)態(tài)中,不能取代have的位置,而應(yīng)與done完美融合。但是,作為進(jìn)行時(shí)態(tài),doing不能改變,所以,只能改變be的形式。be的完成時(shí)形態(tài)為have been,所以完成進(jìn)行時(shí)的動(dòng)詞形式應(yīng)該為 have done+ be doing= have been doing。
在此基礎(chǔ)上,現(xiàn)在完成進(jìn)行時(shí)的形式為“現(xiàn)在”(do/ does)+“完成進(jìn)行”(have been doing),最終形式為have/has been doing。而過(guò)去完成進(jìn)行時(shí)的形式應(yīng)為“過(guò)去”(did)+“完成進(jìn)行”(have been doing),最終形式為had been doing。將來(lái)完成進(jìn)行時(shí)的形式為“將來(lái)”(will do)+“完成進(jìn)行”(have been doing),最終形式為will have been doing。過(guò)去將來(lái)完成進(jìn)行時(shí)的形式則為“過(guò)去將來(lái)”(should / would do)+“完成進(jìn)行”(have been doing),最終形式為should / would have been doing。
綜合以上,我們可以得出各時(shí)態(tài)的形式,總結(jié)為下表:
一般 進(jìn)行 完成 完成進(jìn)行 過(guò)去 did was/ were doing had done had been doing 現(xiàn)在 do/ does am/ are/ is doing have/ has done have/ has been doing 將來(lái) shall/ will do shall/ will be doing shall/ will have done shall/ will have been doing 過(guò)去將來(lái) should/ would do should/ would be doing should/ would have done should/ would have been doing【考研英語(yǔ):掌握16個(gè)動(dòng)詞時(shí)態(tài)的形式和用法5】相關(guān)文章:
