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. 本篇文章来源于考试中国 ；原文链接地址：/ielts/xz/399496.html(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。 who先行词是人，在定从中可以做主语或宾语 Children who study abroad will have a good opportunity to experience a different culture. which先行词必须是物，在定从中可以做主语或宾语 Advertisements often urge people to buy things which they do not need. that先行词既可是人，又可是物，在定从中做主语或宾语 The Internet is a tool that can expand ones horizon. whom先行词是人，在定从中做宾语 Children whom their parents encourage to take part-time jobs will adapt to the society better in the future. whose先行词既可是人，又可是物，在定从中做定语 Children whose parentsguidance is consistent and rational will have more self-confidence.
