考研英语中从句的类型划分存在不同说法，但综合权威信息可归纳为以下两种主流分类方式：
一、按功能划分（三大类）
定语从句 修饰名词或代词，起形容词作用。例如：
*The book which/that I borrowed from the library is very interesting.*
名词性从句
在句中作主语、宾语、表语或同位语，功能相当于名词。 - 主语从句： 如 *What he said surprised everyone.* - 宾语从句
- 表语从句：如 *The problem is that we don't have enough time.*
- 同位语从句：如 *This is the reason why we were late.*
状语从句 表示时间、地点、原因、条件等逻辑关系。 - 时间状语从句：
如 *When she arrived, the meeting had already started.*
- 条件状语从句：如 *If it rains, we will cancel the picnic.*
- 让步状语从句：如 *Although it was raining, we still went for a walk.*
二、状语从句的细分（9种类型）
1. 时间状语从句：如 *Every day at 8 o'clock*
2. 地点状语从句：如 *Where the meeting is held*
3. 条件状语从句：如 *If you study hard, you will pass the exam.*
4. 让步状语从句：如 *Though he was tired, he continued working.*
5. 原因状语从句：如 *Because of the heavy rain, the flight was delayed.*
6. 结果状语从句：如 *As a result of the accident, the company had to shut down.*
7. 目的状语从句：如 *She went to the store to buy some milk.*
8. 方式状语从句：如 *He spoke to me in a very polite manner.*
9. 比较状语从句：如 *He runs faster than his brother.*
总结
核心分类：三大类（定语从句、名词性从句、状语从句）
扩展分类：状语从句可细分为9种类型
重点提示：定语从句是三大从句中的难点，需结合关系代词和介词掌握
建议考生以《考研英语语法》等官方教材为准，结合真题练习巩固各类从句的用法。
