以下是整理的《特殊詞引導的條件狀語從句》，一起來看看吧！
suppose和supposing：
suppose和supposing可用作連詞，引導條件狀語從句，其意為“假若”“如果”等；此時主句通常為疑問句。
eg.Supposing he can’t come, who will do the work? 假使他不能來，這工作誰做?
Supposing he does not come, shall we go without him? 如果他不來，是不是不帶他去?

Suppose [Supposing] (that) we miss the train, what shall we do? 假如我們誤了火車，我們將怎么辦?
provided和providing：
雖然 providing 和 provided 形式上為動詞provide的現(xiàn)在分詞和過去分詞，但它們均可用作連詞，引導條件狀語從句，其意為“只要”（=as long as）、“如果”（=if）等。
eg. Providing [Provided] you clear your desk by this evening, you can have tomorrow off. 只要你到今晚把案頭上的工作做完，你明天就可以休息。
Providing [Providing] you promise not to tell anyone else. I’11 explain the secret. 只要你保證不告訴任何人，我就把這個秘密講給你聽。
Provided [Providing] that you keep quiet, you can come to the concert. 只要你保持安靜，你就可以去聽音樂會。
Providing there is no opposition, we shall hold the meeting here. 如果沒人反對我們將在這里開會。
這類從句通常置于主句之前，但置于主句之后也是可能的。
