高中英语语法知识归纳
名词性从句重难点
1. 在名词性从句中，疑问句要用陈述句的语序。例如：
①Can you make sure ____the gold ring ?(MET90)
A.where Alice had put D.where has Alice put
2. 动词 doubt 用在疑问句或否定句中，其后宾语从句常用 that 作连接词;用在肯定句中，连接词用 whether 或 if 皆可，而不用 that。
3. 否定转移问题。
①将think, believe, suppose, expect, fancy, guess, imagine等动词后面跟宾语从句时否定转移 我想我并不认识你。 我相信他不回来。
We dont expect he will come tonight , will he ?
注意：若谓语动词为hope,宾语从句中的否定词不能转移。 I hope you werent ill. 我想你没有生病吧。
②将seem, appear 等后的从句的否定转移
看来他们不知道往哪去。
看来我们明天不会碰上好天气。
4. 主谓一致问题。 . .
5. 语气问题
① 在含有 suggest , order , demand , propose , command , request , insist, desire, require, advise 等表示要求、命令、建议、决定等意义的动词后，that从句常用“should+ 动词原形”的结构 我建议我们应该立刻出发。
同位语从句就是在复合句中作名词的同位语的名词性从句。
1. 同位语从句的功能
同位语从句对于名词进一步解释，说明名词的具体内容，一般由that引导，例如：
1) The king’s decision that the prisoner would be set free surprised
all the people.
2) The order that all the soldiers should stay still is given by the
general.
2. 同位语在句子中的位置
同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。例如：
He got the news from Mary that the sports meeting was put off.
3. 同位语从句与定语从句的区别
(1) 定语从句中的that既代替先行词，同时以在从句中作某个成分(主语或宾语)，而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。
(2) 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述定的性质或特征;同位语从句是名词性的.，其功能是对名词进行补充说明。
名词性从句
名词性从句就是在句子中充当名词功能的以相关从属连词引导的从句，包括主语从句、宾语从句、表语从句和同位语从句四种。
1．主语从句：以连词 that what whom whose what which whoever whatever whichever where when how why 引导，在句子中充当主语。
例：What she said is not yet known.
How this happened is not clear to anyone.
Whoever comes is welcome.
That she will do well is her exam is certain.（It is certain that she will do well in her exam.）
注：it 为形式主语，
2．宾语从句：以连词 that who whom whose what 等引导，在句子中充当宾语。
例：He told us that he felt ill.
Everybody knows what happened.
I doubt whether he will succeed.
I wonder what he is writing about.
3．表语从句：以 that whether who whom whoever when where when 等引导，在句子中充当表语。
1.主语从句
1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。常见的句型有：
*It is a fact\a pity\a question\good news that...
*It seems\appears\happened\has turned out that...
*It is clear\important\likely\possible that...
*It is said\reported\estimated\has been proved that...
It is said that comic books create a connection between people of the same generation.
It seems that the performance is very useful.
2)what引导的主语从句表示“...的东西时”，一般不用it作形式主语。
What we lack is experience.
3)what,who,when,why,whether等词含有各自的疑问意义，但它们引导的主语从句，都用陈述语序。
引导名词性从句的从属连词有：that和if/whether(是否)等。
We know that the earth goes around the sun.(宾语从句)
I wonder if he has received my e-mail. (宾语从句)
Whether he’ll go there hasn’t been decided.(主语从句)
注意：在时间状语从句和条件状语从句中，如果主句是将来时，从句要用一般现在时。
I’ll go on with the work when I come back tomorrow.
He won’t come unless he is invited.
引导原因状语从句的从属连词有because, as, since等。
because“因为”语气最强,回答why提问时只能用because，其引导的从句可放在句首或句末；as“由于”、since“既然”语气不如because强，引导的从句常置于句首；for是并列连词，语气最弱，对前面分句加以解释或补充说明，其引导的分句常置于句末且用逗号隔开。
He didn’t go to school because he was ill.
As it was raining, we went there by bus.
Since everybody is here, let’s begin.
It must have rained last night, for the ground is wet.
注意：because与so不能同时使用。
以上就是高中从句总结的全部内容，英语八大从句类型与用法总结举例如下：一、定语从句：在复合句中， 修饰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，引导定语从句的有关系代词who，whom，whose，which，that等和关系副词where，when，why等，关系代词和关系副词在定语从句中担任句子成分。二、。
