引導條件狀語從句的從屬連詞有if, unless (=if…not如果不……,除非), as/so long as(只要), while(=as long as只要), supposing (that)/provided /providing (that)(假如), in case(假使), on condition that(在……的條件下)等。如: You can learn anything so long as you set your mind to learn it. 用心學本領,總能學到手。 I will go there tomorrow unless it rains.(=…if it doesn’t rain)除非下雨,否則我明天要去那兒。 He will do the work providing you pay him. 如果你能付費,他可以做這工作。 In case l forget,please remind me about it. 如果我忘了,請提醒我。 We’ll let you use the room on condition that you keep it clean and tidy. 我們可以讓你使用這個房間,條件是你把它保持整潔。 注:條件狀語從句和時間狀語從句一樣,從句的謂語動詞不能用一般將來時態、過去將來時態或將來完成時,而要用相應的一般現在時、一般過去時和現在完成時態來替代。又如: Tell me in case you get into difficulty. 遇到困難請告訴我。 Supposing he does not come, shall we go without him? 如果他不來,是不是不帶他去? 但若從句謂語用了will 或 would,那 will 或 would 則是表示“愿意”的情態動詞。如: If you will go with me, I’ll wait for you. 如果你愿意等我,我們就幫你做這事兒。 |
