if(如果) If he asks me, I will help. 如果他请我相助,我会帮忙的。 注意主句动词和从句动词的时态,须遵循逻辑上的先后关系。 unless(除非) unless = if ... not,这是理解 unless 用法的要领,比如: If it doesn't rain tomorrow, we shall go mountain climbing. = We shall go mountain climbing unlessit rains tomorrow. 我们明天会去爬山,除非下雨。 on condition that ,that 可以省去,可译为“只要” I can tell the truth on the condition thatyou keep the secret. 只要你保守秘密,我可以告诉你真相。 as long as (只要) It's too late. You can go out as long asyou can come back befor 9. 太晚了,只要你 9 点前能回来,你才能出去。 条件状语的位置 状语的位置很灵活,状语从句也是,可以放在主句前,也可以放在主句后,放在主句前的时候,得用个逗号“,”。 If it rains, he will stay at home. He will stay at home if it rains. 如果下雨,他就呆在家里。 好了,条件状语从句就给大家讲到这里,大家记得下去多练习哦。 |
