long.?”句型中。The machine has been used for 3 years.這臺(tái)機(jī)器已經(jīng)使用了三年了。How long has the car been repaired?這部車(chē)修了多長(zhǎng)時(shí)間了?知 識(shí) 與 要 點(diǎn)知 識(shí) 與 要 點(diǎn)2.用在時(shí)間或條件狀語(yǔ)從句中,表示將來(lái)某時(shí)已完成的被動(dòng)動(dòng)作,即用現(xiàn)在完成時(shí)的被動(dòng)語(yǔ)態(tài)代替將來(lái)完成時(shí)的被動(dòng)語(yǔ)態(tài)。You can go home as soon as your task has been finished.你的任務(wù)一完成就可以回家。知 識(shí) 與 要 點(diǎn)知 識(shí) 與 要 點(diǎn)四、使用現(xiàn)在完成時(shí)的被動(dòng)語(yǔ)態(tài)要注意以下幾點(diǎn)1.現(xiàn)在完成時(shí)的被動(dòng)語(yǔ)態(tài)的兩個(gè)助動(dòng)詞,即have/has和been,兩者缺一不可。2.與一般過(guò)去時(shí)的被動(dòng)語(yǔ)態(tài)的區(qū)別。一般過(guò)去時(shí)的被動(dòng)語(yǔ)態(tài)所表示的動(dòng)作或狀態(tài)與現(xiàn)在的情況沒(méi)有聯(lián)系,而現(xiàn)在完成時(shí)的被動(dòng)語(yǔ)態(tài)則強(qiáng)調(diào)與現(xiàn)在的情況有聯(lián)系。The road was built last year.這條路是去年修成的。The road has been built.這條路已經(jīng)修好。知 識(shí) 與 要 點(diǎn)知 識(shí) 與 要 點(diǎn)3.非延續(xù)性動(dòng)詞,如borrow,finish,begin,start,buy,marry,open,join等構(gòu)成的現(xiàn)在完成時(shí)的被動(dòng)語(yǔ)態(tài)不能與表示一段時(shí)間的狀語(yǔ)連用。若要表達(dá)相應(yīng)的意思,則要改換動(dòng)詞或時(shí)態(tài)。How long has this dictionary been borrowed?()How long has this dictionary been kept?()這本字典借了多長(zhǎng)時(shí)間了?但這類(lèi)動(dòng)詞的否定式可表示動(dòng)作的持續(xù)過(guò)程,具有持續(xù)性,因而可與since或for構(gòu)成的時(shí)間狀語(yǔ)連用。This dictionary has not been borrowed since last week.自上周以來(lái)沒(méi)有人借過(guò)這本字典。知 識(shí) 與 要 點(diǎn)知 識(shí) 與 要 點(diǎn)【鏈接訓(xùn)練】How long_at this job?Since 1990.A.were you employedB.have you been employedC.had you been employedD.will you be employed【解析】根據(jù)題中回答since 1990可以確定應(yīng)用現(xiàn)在完成時(shí),又因?yàn)閥ou和employ之間存在被動(dòng)關(guān)系,故此題應(yīng)用現(xiàn)在完成時(shí)的被動(dòng)語(yǔ)態(tài)?!敬鸢浮緽知

told【解析】句意為:杰克已經(jīng)被告知這件事情了,所以你就不必打電話給他了。根據(jù)句意,此題應(yīng)用現(xiàn)在完成時(shí)態(tài),強(qiáng)調(diào)過(guò)去發(fā)生的動(dòng)作對(duì)現(xiàn)在已經(jīng)造成影響,而A、C表示過(guò)去的過(guò)去,用在此處不符合語(yǔ)境。且tell與Jack之間是被動(dòng)關(guān)系,故正確答案為D項(xiàng)?!敬鸢浮緿知

translated【解析】句意為:據(jù)說(shuō)在過(guò)去的10年,紅樓夢(mèng)已經(jīng)被翻譯成數(shù)十種語(yǔ)言。A Dream of the Red Chamber與translate之間存在被動(dòng)關(guān)系,故使用被動(dòng)語(yǔ)態(tài),排除C、D項(xiàng);又translate發(fā)生在said之前,故用現(xiàn)在完成時(shí)的被動(dòng)語(yǔ)態(tài),選擇A?!敬鸢浮緼知 識(shí) 與 要 點(diǎn)知 識(shí) 與 要 點(diǎn)If Newton

years“近幾年來(lái)”確定句子應(yīng)用現(xiàn)在完成時(shí)。再由句子的主語(yǔ)new substances與謂語(yǔ)動(dòng)詞discover之間是被動(dòng)關(guān)系,確定句子應(yīng)用被動(dòng)語(yǔ)態(tài),由這兩個(gè)方面可知應(yīng)用現(xiàn)在完成時(shí)的被動(dòng)語(yǔ)態(tài)?!敬鸢浮緿知 識(shí) 與 要 點(diǎn)知 識(shí) 與 要 點(diǎn)
