秘笈10 特殊句式考点1 倒装倒装是英语中常见的一种语言现象，它具有强调、修饰等作用。

倒装可分为完全倒装和部分倒装。

一、完全倒装完全倒装是指将句子中的谓语动词全部置于主语之前。

此结构通常只用于一般现在时或一般过去时。

常见的结构有：1. There be句型：其中be可换成live, lie, stand, remain, exist, come, go, seem (appear/ happen/ used) to be等表示＂存在＂意义的词。

☛There entered a strange little man. 走进来一个奇怪而身材矮小的人。

☛Once there lived an old fisherman in a village by the sea. 从前，海边的一个村子里住着一位老渔夫。

2. 以here, there, off, out, in, up, down, away, now, then, on等表示方向、位置或时间、地点的副词开头的句子，谓语是come, go, be等动词时，并且其主语为名词时，通常使用完全倒装。

☛Now, here goes the story. 现在，这个故事是这样的。

☛Then came another question. 然后又一个问题被提出来了。

☛Away flew the bird. 那只鸟飞走了。

☛Suddenly, in came a man with a mask on his face. 突然进来一个蒙着面的男人。

在以there, here, up, down, out, in等副词开头的句子中，当主语是代词时，句子不倒装。

☛There they are.他们在那边。

3. 表示地点的介词短语，常将其放在句首，构成完全倒装，用于表示强调。

此时句子的谓语动词通常是不及物动词，且主语为名词。

☛In the cottage lives a family of six. 在这间小屋里住着一家六口。

高中英语知识点整理 2018高考最有可能考的题高中英语知识点整理 2018高考最有可能考的题距离2018年高考越来越近，对于已经进入高三复习的同学，真的是争分夺秒。

下面为大家整理高中英语必考知识点，希望能对大家有所帮助。

高中英语知识点整理：定语从句一. 定语从句的概念在复合句中，修饰某一名词或代词的从句叫定语从句。

被修饰的名词或代词叫先行词，引导定语从句的词叫关系词，定语从句一般放在先行词的后面。

二. 引导定语从句的关系词引导定语从句的关系词有关系代词和关系副词，常见的关系代词包括that， which， who(宾格whom，所有格whose)等，关系副词包括where， when， why等。

关系代词和关系副词放在先行词及定语从句之间起连接作用，同时又作定语从句的重要成分。

三. 定语从句的分类根据定语从句与先行词的关系，定语从句可分为限制性定语从句及非限制性定语从句。

限制性定语从句紧跟先行词，主句与从句不用逗号分开，从句不可省去。

非限制性定语从句与主句之间有逗号分开，起补充说明作用，如省去，意思仍完整。

注意：(1)当定语从句中含有介词，介词放在句末时，who，whom，that，which可省略，但介词在关系代词前时，只能用介词+which/whom结构。

例如：This is the house in which we lived last year.这是我们去年居住的房子。

Please tell me from whom you borrowed the English novel.请告诉我你从谁那借的这本英文小说。

(2)含有介词的固定动词词组中，介词不可前置，只能放在原来的位置上。

例如：This is the person whom you are looking for.这就是你要找的那个人。

(3)that 作介词的宾语时，介词不能放它的前面，只能放在从句中动词的后面。

例如：The city that she lives in is very far away.她居住的城市非常远。
