引導(dǎo)條件狀語(yǔ)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(xué)本領(lǐng),總能學(xué)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(fèi),他可以做這工作。
In case l forget,please remind me about it. 如果我忘了,請(qǐng)?zhí)嵝盐摇?/p>
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(gè)房間,條件是你把它保持整潔。
注:條件狀語(yǔ)從句和時(shí)間狀語(yǔ)從句一樣,從句的謂語(yǔ)動(dòng)詞不能用一般將來(lái)時(shí)態(tài)、過去將來(lái)時(shí)態(tài)或?qū)?lái)完成時(shí),而要用相應(yīng)的一般現(xiàn)在時(shí)、一般過去時(shí)和現(xiàn)在完成時(shí)態(tài)來(lái)替代。又如:
Tell me in case you get into difficulty. 遇到困難請(qǐng)告訴我。
Supposing he does not come, shall we go without him? 如果他不來(lái),是不是不帶他去?
但若從句謂語(yǔ)用了will 或 would,那 will 或 would 則是表示“愿意”的情態(tài)動(dòng)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。
