3. 由as soon as, immediately, directly, instantly, the moment, the instant, the minute, 等引導(dǎo)的時(shí)間狀語(yǔ)從句。這些連詞都表示"一…就"。例如:
I will go there directly I have finished my breakfast. 吃完早飯，我立即到那里去。
The moment I heard the news, I hastened to the spot.我一聽到消息，馬上趕到了出事地點(diǎn)。
As soon as I reach Canada, I will ring you up. 我一到加拿大，就給你來電話。
4.【注意】hardly(scarcely, rarely)…when / before, no sooner…than相當(dāng)于as soon as之意。
主句用過去完成時(shí)，從句用一般過去時(shí)。當(dāng)hardly, scarcely, rarely和no sooner位于句首時(shí)，主句應(yīng)用倒裝語(yǔ)序。例如:
He had no sooner arrived home than he was asked to start on another journey. 他剛到家，就被邀請(qǐng)開始另一旅程。
No sooner had the sun shown itself above the horizon than he got out of bed to commence work.太陽(yáng)剛從地平線上升起，他就起床勞動(dòng)去了。
Hardly had I sat down when he stepped in.我剛坐下，他就進(jìn)來了。
He had hardly fallen asleep when he felt a soft touch on his shoulder.這個(gè)阿拉伯人剛要入睡就感到肩膀上被輕輕一觸。
5.by the time引導(dǎo)的時(shí)間狀語(yǔ)從句：注意時(shí)態(tài)的變化:在一般情況下，如果從句的謂語(yǔ)動(dòng)詞用一般過去時(shí)，主句的謂語(yǔ)動(dòng)詞用過去完成時(shí);如果從句的謂語(yǔ)動(dòng)詞用一般現(xiàn)在時(shí)，主句的謂語(yǔ)動(dòng)詞用將來完成時(shí)。
By the time you came back, I had finished this book.到你回來時(shí)，我已經(jīng)寫完這本書了。
By the time you come here tomorrow, I will have finished this work. 你明天來這兒的時(shí)候，我將已經(jīng)完成此工作了。
6. 由as long as和so long as引導(dǎo)的時(shí)間狀語(yǔ)從句。這兩個(gè)連詞表示"有多久……就多久"。例如:
You can go where you like as long as you get back before dark. 你可以隨意到哪里去，只要在天黑以前回來就行。
I will fight against these conditions as long as there is a breath in my body! 只要我一息尚存，我就要反對(duì)這種境況。
