其实很简单的,unless 和if not有时候可以互换,你这里基本上都是if的从句,所以说你自己也感觉到if和unless 又是什么关系似的.其实unless 和if not有时候可以互换,但在有些情况下不能互换.
1. 当所述条件要引出一种新的想法或情况(而不是结束已存在的想法或状态)时.
2. 当要引出一个表示假想的(imaginary)条件句时.
当这两个情况出现时,你就只能用if ...not,而不能够用unless
1.这句话就不能用unless来改写,因为这是一种条件引出来的一个想法或者情况..
2.和上句类似,所以也不能改写..
3.You cannot have the car tonight unless Harriet doesn't need it,这句就可以改,因为没有我所说的上面两点..
而第四局,第五句和第六句全部都是和第一句,第二句一样的原因,所以我就不必重复解释了...其实很简单的...
希望你喜欢罗..呵呵-_-
