gct英语语法大全
gct的英语语法和我们平时学习的英语语法有其共通之处。下面是学习啦小编给大家整理的gct英语语法，供大家参阅!
gct英语语法：定语从句
引导定语从句的关联词包括：
1关系代词：that, which, whose, who, whom, as. 2关系副词：when, where, why
注意当先行词是all, something, nothing等不定代词时，或者先行词前面有first, last, only, few, much, some, any, no等词修饰时，或先行词前有形容词最高级修饰时，一般只用that而不用which来引导定语从句。
I have explained everything (that) I can to you.
This is the most beautiful campus (that) I have ever been to.
gct英语语法：名词性从句
名词性从句包括主语从句、表语从句、宾语从句和同位语从句。引导这些名词性从句的关联词包括：从属连词that, if, whether;连接代词who, whoever, whom, whomever, which, whichever, what, whatever, whose,连接副词where, when, why, how.其中，从属连词只起到连接作用，在从句中不充当任何句法成分，而连接代词和连接副词既起连接作用，在从句中又充当一定的成分。
1.在含有主语从句的复合句中，为保持句子平衡，常用it作形式主语，而将真正的主语从句置于句末。 It is well known that water is indispensable to life.
2为了保持句子平衡，that 引导的宾语从句也常用it代替，而真正的宾语从句置于主句句末，这常常出现在主句有形容词或分词作宾语补足语的情况下。 He made it quite clear that he preferred to live there.
3从属连词whether和if都作“是否----”解，但if不可引导主语从句和表语从句。Whether 可与or(not)连用，而if不可以。
Whether he comes or not makes no difference.
4 that 和what引导名词性从句的区别：that在从句中不充当成分，而what在从句中充当一定的成分，如主语、表语、宾语等。that可省略，what不可省略。 He always means what he says.
5 同位语从句大多由从属连词that引导，常跟在下列名词后面，如fact, idea, opinion, news, hope, belief等， that不可省略。同位语从句一般用来说明这些名词的具体内容和含义。
We are familiar with the idea that all matter consists of atoms.
The news that we are invited to the conference is very encouraging.

除了以上提到的从属连词有：还有其他一些词和词组也可以引导条件状语从句。如：providing that, provided, supposing that, suppose that, on condition that, in case等。
