【正文】 heir work when I arrived at the office. 2. 過(guò)去完成時(shí)表示動(dòng)作發(fā)生在“過(guò)去的過(guò)去”;而一般過(guò)去時(shí)只表示動(dòng)作發(fā)生在過(guò)去。如: We hadn’t seen each other since I left my hometown. 注意: 1. 過(guò)去完成時(shí)由“助動(dòng)詞 had + 過(guò)去分詞”構(gòu)成。它表示動(dòng)作發(fā)生的時(shí)間為“過(guò)去的過(guò)去”。例如, by the time引導(dǎo)的時(shí)間狀語(yǔ)從句的謂語(yǔ)動(dòng)詞如果用一般過(guò)去時(shí),主句的謂語(yǔ)動(dòng)詞用過(guò)去完成時(shí); by the time引導(dǎo)的時(shí)間狀語(yǔ)從句的謂語(yǔ)動(dòng)詞如果用一般現(xiàn)在時(shí),主句的謂語(yǔ)動(dòng)詞用將來(lái)完成時(shí)。 before引導(dǎo)的從句的動(dòng)作通常發(fā)生在主句動(dòng)作之后,如果從句是過(guò)去時(shí),主句一般要用過(guò)去完成時(shí)。如: As he grew older, he began to go deaf. 4. when, while與 as可通用的情況 when, while與 as都表示主、從句的動(dòng)作或狀態(tài)同時(shí)發(fā)生,當(dāng)從句中的謂語(yǔ)動(dòng)詞為持續(xù)性動(dòng)詞時(shí),這三者可以互相通用。當(dāng)主句、從句動(dòng)作同時(shí)進(jìn)行,從句動(dòng)作的時(shí)間概念淡化,而主要表示主句動(dòng)作發(fā)生的背景或條件時(shí),只能用 as。所以 while往往與延續(xù)性動(dòng)詞連用,不與瞬間動(dòng)詞連用,且謂語(yǔ)動(dòng)作通常與主句的謂語(yǔ)動(dòng)作同時(shí)發(fā)生。如: When she finished her homework, she went to the supermarket with her friend. When he got to the station, the train had already left. When I lived in the countryside, I used to carry some water for him. 注意:主句為將來(lái)時(shí)的時(shí)間狀語(yǔ)從句,常用 when來(lái)引導(dǎo),時(shí)間狀語(yǔ)從句用現(xiàn)在時(shí)表示將來(lái)時(shí)。 when, while與 as引導(dǎo)的時(shí)間狀語(yǔ)從句 1. when可指一段時(shí)間,也可指某個(gè)具體時(shí)間,所以 when引導(dǎo)的從句的謂語(yǔ)動(dòng)詞可以是延續(xù)性動(dòng)詞,也可以是瞬間動(dòng)詞。Module 3 Music Adverbial clause of time 狀語(yǔ)從句 狀語(yǔ)從句在句中起狀語(yǔ)作用,修飾主句的謂語(yǔ)動(dòng)詞、形容詞、副詞或整個(gè)句子。 狀語(yǔ)從句按用途可分為時(shí)間狀語(yǔ)從句、地點(diǎn)狀語(yǔ)從句、原因狀語(yǔ)從句、條件狀語(yǔ)從句、目的狀語(yǔ)從句、結(jié)果狀語(yǔ)從句、讓步狀語(yǔ)從句、比較狀語(yǔ)從句和方式狀語(yǔ)從句。它所引導(dǎo)從句的動(dòng)作可以與主句的動(dòng)作同時(shí)發(fā)生、先于或者后于發(fā)生。如: When the president es here for a visit next month, I’ll give the wele speech. 2. while只能表示持續(xù)性的動(dòng)作或狀態(tài),不能表示暫時(shí)性或短暫性的動(dòng)作。如: While I’m running, I’m thinking about all sorts of things about my future. While my mom was cooking in the kitchen, I was watching the latest movie in my room. 3. as表示“隨著 …… ;一邊 …… ,一邊……‖ 。 as所表示的動(dòng)作具有延續(xù)的含義,一般同延續(xù)性動(dòng)詞連用,通常是和主句的謂語(yǔ)動(dòng)作同時(shí)發(fā)生,不可以在主句的謂語(yǔ)動(dòng)詞的之前或者之后。如: When / While / As the teacher was discussing the topic with us, the headmaster came in. after, before與 by引導(dǎo)的時(shí)間狀
