2、的從句謂語用的是過去時，則主句動詞多用過去完成時，這樣以便體現(xiàn)動作發(fā)生的先后。 after表示主句動作發(fā)生在從句動作之后。主句和從句的動作的時間關系正好與before引導的從句相反。2021/8/9 星期一5It will be four days before they come back.他們要過四天才能回來。Einstein almost knocked me down before he saw me. 愛因斯坦幾乎把我撞倒才看到我。 After you think it over, please let me know what you decide. 你仔細考慮過以后，告訴我你的決

6、來電話。2021/8/9 星期一11注意：hardly (scarcely, rarely)when / before, no soonerthan相當于as soon as之意。主句用過去完成時，從句用一般過去時。當hardly, scarcely, rarely和no sooner位于句首時，主句應用倒裝語序。He had hardly fallen asleep when he felt a soft touch on his shoulder.No sooner had the sun shown itself above the horizon than he got out of

7、bed to commence work. 2021/8/9 星期一125. 由by the time引導的時間狀語從句要注意時態(tài)的變化：在一般情況下，如果從句的謂語動詞用一般過去時，主句的謂語動詞用過去完成時；如果主句的謂語動詞用一般現(xiàn)在時，主句的謂語動詞用將來完成時。如： By the time you came back, I had finished this book.By the time you come here tomorrow, I will have finished this work. 2021/8/9 星期一136. 由each time, every time和w
