【文章內(nèi)容簡介】 同，但是較正式的說法。However在句中位置較靈活，在句首時，后面常用逗號。如：He was wealthy. However, he was very mean(吝嗇的). 現(xiàn)在完成進行時?，F(xiàn)在完成進行時強調(diào)動作從過去某個時間一直持續(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 + been doing… （一般疑問句形式）特殊疑問句形式將疑問詞置于句首我們來看一個例子：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?這幾個單元中的一個難點是虛擬條件句。虛擬條件句表示與事實相反的愿望、假想。同學們先掌握與現(xiàn)在事實相反的虛擬條件句。其結(jié)構(gòu)是：If + 從句主語 + 動詞過去式，主句主語+ would (‘d) +動詞原形。例如：If I had the time, I’d make something better.在這種與現(xiàn)在事實相反的虛擬條件句中，需要注意的是，不論主語是什么人稱，be動詞都常用were，如：If I were you, I’d ask her. 現(xiàn)在我們看看進行時的被動態(tài)形式。進行時被動語態(tài)分為現(xiàn)在進行時被動語態(tài)和過去進行時被動語態(tài)。這兩種被動語態(tài)的時態(tài)是通過be動詞來體現(xiàn)的。我們分別來看它們的基本結(jié)構(gòu)：現(xiàn)在進行時被動語態(tài)：be ( am / is / are) + being + 動詞過去分詞過去進行時被動語態(tài)：be (was / were ) + being + 動詞過去分詞這兩種被動語態(tài)的否定形式和疑問句形式都是在be動詞上發(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? 間接引語也學習過。要注意的是間接引語中主句時態(tài)和從句時態(tài)的一致性原則。一般來說，如果主句謂語動詞為過去時，在將直接引語變?yōu)殚g接引語時，要將直接引語中
