減譯法：由于英漢兩種語言在語法結構、表達方式以及修辭手段上的不同，有些詞語或句子成分在英語中是必不可少的，但若搬到譯文中去，就會影響譯文的簡潔和通順。因此在英譯漢的過程中，為了使譯文更加簡練，更符合漢語的表達習慣，需要省略一些可有可無或翻譯后反嫌累贅的詞語。但必須注意，減譯不是刪掉原文中的某些內容，在不易減譯的情況下，不要隨便減。

It was stipulated that the goods should be delivered in three days.規(guī)定三天后發(fā)貨。(it是形式主語，that是先行詞)
2)省略冠詞。如:

3)省略連詞。如:

5)省略名詞。如:Perhaps you have overlooked the fact that your account for May purchases has not yet been settled.也許你忘記了五月份的購貨款還沒有結算。(fact后面引導的是一個同位語從句，可以不譯)
