B:六类从句句型归纳总结
从句是相对于主句而言的，即它是从属于某一个主句，而不能单独作一个句子。在英语中，主要有三大从句，即名词性从句(包括主语从句，宾语从句，表语从句，同位语从句)、形容词性从句(即定语从句)、副词性从句(即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式和比较九种。)
(1) 形式主语从句句型
形式主语从句是写作中非常常用的一种从句。我们先来看一下它是如何构成的。(That+一个完整的句子可做主语)。比如说：(That education is important ) is clear.这就是主语从句的基本形式。但如果句子要是这样，主语过长。所以，我们习惯于用it来代替原来的主语。而把原来的主语放在句子的最后。这句话可改为：It is clear that education is important.这就叫做形式主语从句。
1It is often the case that
2It is a fact that
(2) 宾语从句句型
宾语从句是写作中非常常用的另一种从句。它一般用来提出观点。
1Some people think that
2 Some people believe that
(3) 表语从句句型
表语从句是写作中非常常用的另一种从句，可构成各种句型。
1 The first thing to be mentioned is that
2 Another point to be considered is that
3 The last thing to be shown is that
(4) 同位语从句句型
同位语从句是写作中非常常用的另一种从句，与其前面所修饰名词形成同位关系。
1 I have a dream that one day, all roads will be made plain.
2 We hold this truth to be self-evident that all men are created equal.
(5) 定语从句句型
定语从句是写作中非常常用的另一种从句，常常起修饰的作用。

② which先行词必须是物，在定从中可以做主语或宾语
