　　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)。
