英语中有许多句子，形式上是肯定的，但是其意思却是否定的，这是因为英语中有许多表示否定意思的词和词组。
首先一类是所谓“准否定词，包括few, little, hardly, rarely, scarcely, barely, seldom:

在以since 引出的时间状语从句中，表示状态的持续动词译成汉语时，往往要译成否定的意思，如：It is now six months since he (last ) smoked. 他有6个月没有抽烟了。“他抽烟已有6个月了”应译作It is now six months since he started smoking.( 其中started是一个短暂动词。)

另外，在would rather (sooner)…than…, had rather (sooner)…than…, prefer…rather than (to ) …, would as soon…as…, let alone…等结构中的后一个动语翻译时一般也译作否定的意思。如：
