在考研英语路上，长难句一直是大家望尘莫及的一部分，其句子冗长结构复杂，理解起来非常有难度，需要考生对句子的结构和组成部分有深刻的理解。小编整理了考研英语语法难点之倒装句的相关知识点整理，希望各位考研人在遇到长难句的时候有所帮助。
在英语的语言实践中，为了语法、修辞、结构上的多样性，往往要改变句子的自然语序，把一些本应置于主语之后的句子成分提到主语之前，我们把这种语序的变化称为“倒装语序”。倒装是一种修辞手段，目的是为了强调。
一般情形相对于来说大家比较熟知，但有时候一般疑问句也是属于倒装句的一种，比如：Could you please give me the pen?那么什么情况下会发生部分倒装呢? 只有了解引起倒装的原因，才能更准确地理解句子的含义。
一．倒装句的分类：全部倒装和部分倒装。
英语的基本语序是“主语 谓语”，这种语序称为陈述句语序或者自然语序（normal word order），如果把谓语的全部或者一部分置于主语之前，就称其为倒装语序（inverted word oeder）,当谓语全部位于主语之前，我们称其为全部倒装（full inversion）;当谓语一部分位于主语之前，我们称其为部分倒装（partial inversion）。
二．全部倒装
1. 定义：将谓语动词全部置于主语之前，即动词 主语。

On the mountain stood a temple.
In the temple lived an old monk.

三．部分倒装
1. 定义：将谓语动词的一部分（如助动词或情态动词）置于主语之前为部分倒装（实义动词位置不发生改变）。
2. 部分倒装的识别及还原
识别：若助动词或情态动词后出现名词则判断为部分倒装。
还原：将助动词、情态动词还原，助动词有时需要去掉。
