初中英语语法英语从句总结
初中英语语法总结（从句）
从句分为定语从句，状语从句和名词从句三大类。定语从句又分为限定性和非限定性从句两种，由关系代词或关系副词引导，修饰主句的某个成分。状语从句分为时间、结果、让步、原因、条件及行为方式状语从句。名词从句包括主语、宾语、表语和同位语从句及there be句型。
主系表结构、主谓（宾）结构、there be结构是英语的三大基本句式，无论一个句子有多长、多复杂，它总是属于这三大句式中的一种。
学习基本句式，句子成分是一个关键的概念，它是指句子的组成单位，不同的句式由不同的句子成分组成。如：主系表结构的成分有主语、系动词、表语；主谓（宾）结构的成分有主语、谓语、宾语；there be 结构的主要成分是主语。
英语中的句子成分主要有：主语、谓语、宾语、定语、状语、补语、同位语，等等。这些句子成分可以由单词、词组或句子充当，当这些成分由句子充当时，我们就有了相应的从句，如：充当主语成分的句子为主语从句，充当宾语成分的句子为宾语从句，等等。
