had been doing 我知道是過(guò)去完成時(shí),但不知道是第幾人稱用的?是第三人稱用的嗎?請(qǐng)?jiān)敿?xì)點(diǎn),謝謝

“had been doing”這句話是什么時(shí)態(tài)?

1、首先要區(qū)分has been done與 had been done的區(qū)別: have/has been done 是現(xiàn)在完成時(shí)的被動(dòng)語(yǔ)態(tài)。表示某事被做,。 如:The problems have been solved.這些問(wèn)題已經(jīng)被解決了。 had been done 則是過(guò)去的過(guò)去,是過(guò)去完成的被動(dòng)態(tài)時(shí)。(當(dāng)你想說(shuō)發(fā)生在過(guò)去的兩件事時(shí),就要分清誰(shuí)先誰(shuí)后。先發(fā)生的用過(guò)去完成時(shí),后發(fā)生的要用過(guò)去時(shí))。 如:The rooms had been cleaned when I came. 我來(lái)的時(shí)候,房間已經(jīng)被打掃了。 2、區(qū)分has/have been doing與 had been doi

英語(yǔ)中has done,had done,being done,be done,have been done,had been done,這些時(shí)態(tài)要怎么用。特別亂

has done是現(xiàn)在完成時(shí)態(tài),且主語(yǔ)是單數(shù)第三人稱,比如,He has finished his homework now,so his mother allows him to play outdoors.had done是過(guò)去完成時(shí)態(tài),主語(yǔ)任意皆可 比如He had finished his homework yesterday afternoon,so his mother allowed him to play outdoors.being done是現(xiàn)在進(jìn)行時(shí)態(tài)的被動(dòng)語(yǔ)態(tài),意為“正被……”比如:The building is being built now by the gover

had been和havebeen怎么用

had been是過(guò)去完成時(shí),表示去過(guò)什么地方,也是對(duì)過(guò)去已經(jīng)做過(guò)的事的描述. eg:I had been there.我去過(guò)那里. have/has been 是現(xiàn)在完成時(shí),前者用于第一人稱或復(fù)數(shù)(I或they等),后者用于第三人稱單數(shù)(she或he或someone 等),he has been there.他去過(guò)那里(不管有沒有回來(lái)). 下面是術(shù)語(yǔ)意義: 過(guò)去完成時(shí) : 1) 概念:表示過(guò)去的過(guò)去 過(guò)去完成時(shí):即過(guò)去的過(guò)去所發(fā)生的事情! 其構(gòu)成是主語(yǔ)+had +過(guò)去分詞. 那時(shí)以前 那時(shí) 現(xiàn)在 2) 用法 a.在told,said,knew,heard,thought等動(dòng)詞后的賓語(yǔ)從句.

has been done跟has been doing有什么區(qū)別

又到了為小伙伴們解惑的時(shí)候了??(???????)??,has been done強(qiáng)調(diào)的是動(dòng)作的完成狀態(tài),側(cè)重于結(jié)果。has been doing強(qiáng)調(diào)的是動(dòng)作的持續(xù)狀態(tài),側(cè)重于過(guò)程。這里就給大家總結(jié)了一個(gè)它們基礎(chǔ)知識(shí)的表格,可以先簡(jiǎn)單了解一下先:

了解完它們的基礎(chǔ)知識(shí)后,現(xiàn)在就來(lái)看看它們的具體區(qū)別吧?(??? )?

1、時(shí)態(tài)不同

has been done是過(guò)去完成時(shí)態(tài),表示某個(gè)動(dòng)作或事件在過(guò)去已經(jīng)完成。has been doing是過(guò)去進(jìn)行時(shí)態(tài),表示某個(gè)動(dòng)作或事件在過(guò)去一段時(shí)間內(nèi)一直在進(jìn)行。

例句:

① The report has been done.這份報(bào)告已經(jīng)完成了。

② He has been doing his homework for two hours.他已經(jīng)做作業(yè)兩個(gè)小時(shí)了。

2、動(dòng)作狀態(tài)不同

has been done強(qiáng)調(diào)的是動(dòng)作的完成狀態(tài),側(cè)重于結(jié)果。has been doing強(qiáng)調(diào)的是動(dòng)作的持續(xù)狀態(tài),側(cè)重于過(guò)程。

例句:

① The dishes have been done.碗碟已經(jīng)洗好了。

② She has been doing yoga every morning.她每天早上都在做瑜伽。

3、句子結(jié)構(gòu)不同

has been done通常作為被動(dòng)語(yǔ)態(tài)的形式出現(xiàn),表示動(dòng)作的接受者或受影響者。has been doing通常作為進(jìn)行時(shí)態(tài)的形式出現(xiàn),表示動(dòng)作的執(zhí)行者或主體。

例句:

① The project has been done by a team of experts.這個(gè)項(xiàng)目是由一支專家團(tuán)隊(duì)完成的。

② He has been doing all the housework lately.最近他一直在做家務(wù)。

一個(gè)英語(yǔ)句子中,主語(yǔ)是第三人稱單數(shù),這個(gè)句子又是過(guò)去式,動(dòng)詞用什么形式?

您好,一個(gè)英語(yǔ)句子中,假如句子是過(guò)去式,而主語(yǔ)是第三人稱單數(shù),動(dòng)詞本身是沒有區(qū)分三單或是單復(fù)數(shù),只有用來(lái)構(gòu)成過(guò)去式的(助動(dòng)詞)有區(qū)分三單,但也僅有 be 助動(dòng)詞,其余的助動(dòng)詞都沒有區(qū)分: 1)一般過(guò)去時(shí):三單的(be 動(dòng)詞)用 was;比如 he was 2)過(guò)去進(jìn)行時(shí):三單的(be 助動(dòng)詞)用 was;比如 he was doing 3)過(guò)去完成時(shí):沒有區(qū)別,全部使用 had done 4)過(guò)去完成進(jìn)行時(shí):沒有區(qū)別,全部使用 had been doing
