解析:if…not和unless有时可以互相替换,但也有不能互相替换的时候。unless用于这样的句子,即如果A不受阻于B,A将发生,例如:He will accept the job if the salary is not too low / unless the salary is too low . (如果薪水不太低,他就会接受这一工作/除非薪水太低,否则他会接受这一项工作的。)但是unless不能用于由于未发生B而发生A的句子里,如:I will be quite glad if she does not come this evening (她今天晚上要是不来,我才高兴呢。)又如:I will be surprised if he does not win the game next week . (如果他赢不了下星期那场比赛,我倒会感到惊奇的。)在以上的两个句子中不能使用unless,但是unless常用来引导一个谈及过去的事后的想法,unless从句跟着主句,通常用破折号而不是逗号将它与主句分开。第7题的句意是:我不可能准时到会了-除非我当时赶上更早一列火车。这个句子的实际是说:我没有准时到会。我只有赶上更早的一趟火车,才能准时到会。如果用if … not代替上面句中的unless,那么这个句子就变成:I couldn have got to the meeting on time if I hadn caught an earlier train . (要不是我赶上了更早的一班火车,我就不可能准时到会。)这句话表达的意思与上句完全相反:我确实准时到会了,因为我赶上了更早的一趟火车。
