2013考研英语基础班讲义考研英语长难句解析一、考研英语长难句之定语从句一、定语从句定语从句是英语中一种最常见的句型，它可以分为限制性定语从句和非限制性定语从句，即定语从句的关系词在文中修饰哪个词、短语或句子。
在主句中不可缺少的定语从句称限定性定语从句。
对主句起附加说明作用的定语从句称非限定性定语从句。
此外，定语从句和主句之间还存在着状语关系，说明原因、目的、让步、假设等。

英语的最基本的结构是主、谓结构，倒装就是将这种比较固定的词序加以颠倒。
倒装有两种。
将主语和谓语完全颠倒过来，叫做完全倒装(complete inversion)。
如Then began a bitter war between the two countries.于是两国之间开始了恶战。
只将助动词(包括情态动词)移至主语之前，叫做部分倒装(partial inversion)。
如At no time was the entrance left unguarded.入口无时无人把守。
英语句子的倒装一是由于语法结构的需要而进行的倒装，二是由于修辞的需要而进行的倒装。
前一种情况，倒装是必须的，否则就会出现语法错误，后一种情况，倒装是选择性的，倒装与否只会产生表达效果上的差异。
