7．邏輯關系表達方式

（1）以when, whenever, as, since, till, until, before, after, as soon as, once, the moment, the instant, immediately, the day, no sooner．．．than, hardly/scarcely．．．when, instantly, every time, the minute, the second等引導的時間狀語從句：

Susan worked in the library until she transferred（調轉，調任）to the Advanced Training Center of State Power Corporation．

I'll ring you up as soon as I get an answer from Charlie．

Once she has made up her mind, Ross will never change．

Arthur and Molly were lovers when they were at college．

注意：when, while和as 引導時間狀語從句時用法上的區別。

When既可表示一時性的動作又可表示持續的動作；while不能表示一時性或短暫的動作，只能表示持續性的動作或狀態；as則表示兩個動作同時進行或一個動作和一個狀態同時進行。如：

As Professor Li entered, the hall burst into thunderous applause（雷鳴般的掌聲） ．

Till和until用法上的異同。

Till可用作及物動詞，如：Farmers till the land．（農夫種田）；until則不能用作動詞；until 比till強調，故用于句首時通常用until而不用till，在口語中常用till而不用until; Not until的強倒裝調句式不能用till替換，但注意not until開頭的強調結構用于It is （was）…that 這一強調句中時，從句和主句的主謂均不倒裝。如：It was not until Grace fell asleep that I left the room．

（2）由從屬連詞where, wherever, everywhere引導的地點狀語從句表示的從屬結構：

Wherever you go, I will be with you．

（3）由if, unless, providing/provided （that）, as long as, so long as, on condition that, suppose, supposing that, in case, if only引導的條件狀語從句。
