今天介绍的是考研英语长难句中插入句和倒装句的内容，语法的相关内容希望大家重点掌握。

部分：插入句

一、理论常识

插入结构表示说话人的态度和看法，解释或者说明整个句子，去掉之后句子仍然完整。插入结构的成分可以是副词、形容词短语、介词短语、不定式短语、分词短语或者主谓结构。在这就不一一论述了。但值得注意的是插入语的翻译，有些插入语，尤其是位于句首的插入语，可保持原文中的词序。然而，在许多情况下，需要对英语原文句子的顺序作必要的调整，使译文符合汉语习惯。

二、试题举例

But , for a small group of students , professional training might be the way to go since well-developed skills , all other factors being equal , can be the difference between having a job and not .

【参考翻译】但是，对一小部分学生来说，专业训练也是条可取的路径。因为在其他因素相同的情况下，技能的娴熟是得到工作与否的关键。

二、试题举例
