减译法：由于英汉两种语言在语法结构、表达方式以及修辞手段上的不同，有些词语或句子成分在英语中是必不可少的，但若搬到译文中去，就会影响译文的简洁和通顺。因此在英译汉的过程中，为了使译文更加简练，更符合汉语的表达习惯，需要省略一些可有可无或翻译后反嫌累赘的词语。但必须注意，减译不是删掉原文中的某些内容，在不易减译的情况下，不要随便减。

We are pleased to have received your invitation to the symposium on internet.非常高兴收到你寄来的参加互联网会议的邀请。（省略代词“我们”）

It was stipulated that the goods should be delivered in three days.规定三天后发货。（it是形式主语，that是先行词）

3）省略连词。如：

5）省略名词。如：
