【文章內(nèi)容簡(jiǎn)介】 同，但是較正式的說(shuō)法。However在句中位置較靈活，在句首時(shí)，后面常用逗號(hào)。如：He was wealthy. However, he was very mean(吝嗇的). 現(xiàn)在完成進(jìn)行時(shí)。現(xiàn)在完成進(jìn)行時(shí)強(qiáng)調(diào)動(dòng)作從過(guò)去某個(gè)時(shí)間一直持續(xù)到現(xiàn)在，而且還要繼續(xù)下去。其基本構(gòu)成是：have / has + been doing… （基本結(jié)構(gòu)）have / has not + been doing… （否定形式）Have / has + 主語(yǔ) + been doing… （一般疑問(wèn)句形式）特殊疑問(wèn)句形式將疑問(wèn)詞置于句首我們來(lái)看一個(gè)例子：I’ve been working here for three years.I haven’t been working here for three years.Have you been working here for three years?How many years have you been working here?Who have been working here for three years?這幾個(gè)單元中的一個(gè)難點(diǎn)是虛擬條件句。虛擬條件句表示與事實(shí)相反的愿望、假想。同學(xué)們先掌握與現(xiàn)在事實(shí)相反的虛擬條件句。其結(jié)構(gòu)是：If + 從句主語(yǔ) + 動(dòng)詞過(guò)去式，主句主語(yǔ)+ would (‘d) +動(dòng)詞原形。例如：If I had the time, I’d make something better.在這種與現(xiàn)在事實(shí)相反的虛擬條件句中，需要注意的是，不論主語(yǔ)是什么人稱，be動(dòng)詞都常用were，如：If I were you, I’d ask her. 現(xiàn)在我們看看進(jìn)行時(shí)的被動(dòng)態(tài)形式。進(jìn)行時(shí)被動(dòng)語(yǔ)態(tài)分為現(xiàn)在進(jìn)行時(shí)被動(dòng)語(yǔ)態(tài)和過(guò)去進(jìn)行時(shí)被動(dòng)語(yǔ)態(tài)。這兩種被動(dòng)語(yǔ)態(tài)的時(shí)態(tài)是通過(guò)be動(dòng)詞來(lái)體現(xiàn)的。我們分別來(lái)看它們的基本結(jié)構(gòu)：現(xiàn)在進(jìn)行時(shí)被動(dòng)語(yǔ)態(tài)：be ( am / is / are) + being + 動(dòng)詞過(guò)去分詞過(guò)去進(jìn)行時(shí)被動(dòng)語(yǔ)態(tài)：be (was / were ) + being + 動(dòng)詞過(guò)去分詞這兩種被動(dòng)語(yǔ)態(tài)的否定形式和疑問(wèn)句形式都是在be動(dòng)詞上發(fā)生變化。例如：His behaviour is not being blamed by the public. Were 200 people being treated?Where were 200 people being treated? 間接引語(yǔ)也學(xué)習(xí)過(guò)。要注意的是間接引語(yǔ)中主句時(shí)態(tài)和從句時(shí)態(tài)的一致性原則。一般來(lái)說(shuō)，如果主句謂語(yǔ)動(dòng)詞為過(guò)去時(shí)，在將直接引語(yǔ)變?yōu)殚g接引語(yǔ)時(shí)，要將直接引語(yǔ)中
