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。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.太陽剛從地平線上升起,他就起床勞動去了。
Hardly had I sat down when he stepped in.我剛坐下,他就進來了。
He had hardly fallen asleep when he felt a soft touch on his shoulder.這個阿拉伯人剛要入睡就感到肩膀上被輕輕一觸。
5.by the time引導的時間狀語從句:注意時態的變化: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;如果從句的謂語動詞用一般現在時,主句的謂語動詞用將來完成時。
By the time you came back, I had finished this book.到你回來時,我已經寫完這本書了。
By the time you come here tomorrow, I will have finished this work. 你明天來這兒的時候,我將已經完成此工作了。
6. 由as long as和so long as引導的時間狀語從句。這兩個連詞表示"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,我就要反對這種境況。
