5-5 还盘
3句英文任你选
We regret we have to decline your offer.
很抱歉，我们不得不拒绝你方报盘。
We can't accept your offer unless the price is reduced by 7%.
除非你们减价7%，否则我们无法接受报盘。
We are not interested unless your price is reduced to a level in line with the market price.

半个句型要记牢
Tip:unless是从属连词，引导条件状语从句，含有否定意义，相当于 if条件状语从句的否定形式 (if... not)。常用来引导一个含否定意义的真实条件句，有时也可引导非真实条件句。 unless引导条件句时，可能会出现下列两种情况:
(1)主句为肯定句。例如 You'll fail in math again unless you work har-der. (如果你不再加把劲学习，你数学考试还会不及格。 )
(2)主句为否定句。例如 1 wouldn't be saying this unless I were sure of the facts. (要是我对这些事情没有把握，我就不说这话了)。
