高中的英语知识内容多而杂，不是随随便便就能学好的。想学好就要下功夫，多看书，勤复习。下面是本站小编为大家整理的高中生英语基础知识总结，希望对大家有用!
1)which可以引导非限定性定语从句，代表前面整个句子的内容，并且在从句中做主语 2)that的用法 1)不用that的情况
a) 在引导非限定性定语从句时。 b) 介词后不能用。
We depend on the land from which we get our food. We depend on the land that/which we get our food from.
2) 只能用that作为定语从句的关系代词的情况 a) 在there be 句型中，只用that，不用which。
b) 在不定代词，如：anything, nothing, the one, all, much, few, any, little等作先行词时，只用that，不用which。
c) 先行词有the only, the very修饰时，只用that。 d) 先行词为序数词、数词、形容词最高级时，只用that。. e) 先行词既有人，又有物时。
举例：

3) as的用法
AS作关系代词,用来引导定语从句:限制性定语从句和限非制性定语从句 一、AS引导限制性定语从句
AS引导限制性定语从句时,通常和such, the same, as(so)等连用,构成 as, the same as, as(so)等结构,在从句中可作主语,宾语和表语。
as意为―...的那种...,像那样的‖， as引导限制性定语从句时,既可指人,也可指物。such用于名词之前时,具有形容词性质;such单独使用(即后面不接名词)时,具有代词性质。
Don‘t trust such men as praise you to your face.(as作主语) 不要相信那种当面吹捧你的人。
You should read only such books as you can understand without much difficulty.(as作宾语) 你应当只读那些你读起来不太难懂的书。
Associate with such as will improve your manners.(as作主语) 要和能改善你的言行的那种人结交。
same as意为―与...同样的‖,和such一样,the same既有形容词作用,又有代词性质。
We have arrived at the same conclusion as they have.(as作宾语) 我们已得出和他们同样的结论。
比较:the 和the 不同,前者是―同那一个相似‖,后者是―正是那一个‖。如：
This is the same watch as I lost. 这同我丢的那块表一样。
This is the same watch that I lost? 这正是我丢的那块表。
(so)意为―和...一样‖,后接由many, much等修饰的名词或由形容词修饰的'单数名词,注意其语序为as(so)+adj.+a+n+as,如： It‘s as pleasant a film as I have ever seen. 这是一部和我以往看的同样好的电影。
As many soldiers as marched were killed. 很多游行的战士都被杀了。
注意:such 与 ,与 的区别: that是连词,引出结果状语从句,在从句部分不作成分;as是关系代词,引出定语从句,在从句中可作主语,宾语和表语。比较: He is such a nice boy that everyone likes him. He is such a nice boy as everyone likes.
It is so difficult a problem that nobody can work it out. It is so difficult a problem as nobody can workout.

高中英语重点知识There be句型
(1)There be 句型主要用以表达“某处(某时)有某人(某物)。”其基本结构为“There be+某物(某人)+某地(某时)”其中there是引导词，没有词义;主 语是be后面的名词， be是谓语动词，在一般现在时中be只用is和are两种形式。下面这首歌诀可帮你巧记there be句型结构：
There be放句首，主语跟在后。地、时放句末，强调置前头。如：There is a book on the desk.有时为了强调地点，也可把介词短语放在句首。
如：
On the desk there is a book.
(2)There be 句型中的be动词如何确定呢?请先看看下面这首歌诀：Be动词，有三个，am，is还有are。“There be”真特别，不留am只留俩，那就是is 还有are。要用is还是are，须看其后的名词是单数还是复数。若是单数或不可数名词用is，否则就用are。
如：①There is a tree behind the house.
②There is some water(水)in the bottle(瓶子).
③There are some pears in the box.
(3) 注意：如果“be”后的主语是由and连接的两个或两个以上的名词，那么be的形式要遵循“远亲不如近邻”的原则。也就是说，“be”的形式是由与它最近 的那个名词来确定的。若那个名词是单数或不可数名词要用is，是复数就用are。
