从句的用法归纳总结
从句的用法归纳总结从句是英语语法中重要的一部分，它是指用一个句子来作为另一个句子的一个部分。
从句可以用来表达更复杂的意思，也可以用来让句子更加简洁。
下面将从六个方面来归纳总结从句的用法。
1. 从句类型从句可以分为三大类：名词性从句、形容词性从句和副词性从句。
名词性从句是指用一个句子来作为名词，例如：I think that he will come.（我认为他会来。
）其中that he will come就是一个名词性从句。
形容词性从句是指用一个句子来作为形容词，用来描述主语或宾语的特点，例如：He is a student that always studies hard.（他是一个总是努力学习的好学生。
）其中that always studies hard就是一个形容词性从句。
副词性从句是指用一个句子来作为副词，用来描述主句中的动词或形容词的情况，例如：When he comes, we will go to the party.（当他来的时候，我们会去参加聚会。
）其中When he comes就是一个副词性从句。
2. 从句引导词从句的引导词有很多种，不同的引导词可以引导不同类型的从句。
常用的引导词有：* that：可以引导名词性从句和形容词性从句，但是不能引导副词性从句；* what：可以引导名词性从句；* who：可以引导名词性从句和副词性从句；* whom：可以引导名词性从句；* which：可以引导名词性从句；* where：可以引导副词性从句；* when：可以引导副词性从句；* why：可以引导名词性从句；* how：可以引导名词性从句和副词性从句。
3. 从句语序在英语中，主句和从句的语序一般是不同的。
主句通常采用陈述语序，而从句则可以采用疑问语序或倒装语序。
例如：Do you know where he lives？（你知道他住在哪里吗？）其中where he lives就是一个名词性从句，采用了疑问语序。
