语法核心定义
so that / in order that 引导目的状语从句
核心含义：为了……；以便……
作用：说明主句动作发生的目的和意图
回答问题：可直接回答Why引导的特殊疑问句
基本结构
核心公式：主句 + so that / in order that + 从句
从句要求：必须是完整句子，含主语+谓语
关键注意1：从句常搭配情态动词使用
关键注意2：二者均不能用于句首
so that与in order that 语气区别
so that：语气口语化，日常交流、写作常用
in order that：语气更正式，多用于书面语、正式文体
二者功能：表意完全一致，可互相替换
例句：I study hard so that I can pass the exam.（日常）
时态与情态动词搭配（一）
主句时态 从句常用情态动词 核心说明
现在时 can / will 表现在的目的和能力
将来时 can / will 表将来的目的和意愿
例句：I read English every day so that I can improve it. 时态与情态动词搭配（二）
主句时态 从句常用情态动词 核心说明
过去时 could / would 表过去的目的和意愿
例句：He studied hard in order that he could go to college. 译：他努力学习，为了能考上大学。 小练习 匹配时态与情态动词
1.She works hard so that she______ get a prize.（现在时）
2.They left early so that they______ catch the train.（过去时）
3.I will practice so that I______ speak it well.（将来时）
（填入合适的情态动词，体会搭配规则）
can
would
will
关键细节1 so that的省略用法
核心规则：so that中的that可直接省略，写成so
省略后：so 单独引导目的状语从句，用法不变
例句1：I call her so that I can know her news.
例句2：I call her so I can know her news.（省略that，同义）
注意：in order that 不可省略that
关键细节2 否定目的的表达
方式1：从句用情态动词否定式（can’t/couldn’t/won’t/wouldn’t）
方式2：从句用don’t/doesn’t/didn’t + 动词原形
例句1：I take a hat so that I won’t get sunburned.
例句2：He studies hard so that he doesn’t fail the exam.
否定目的 例句解析
例句：She walked quietly so that she wouldn’t wake the baby.
译：她轻步走，为了不吵醒宝宝。
主句时态：过去时walked
从句搭配：wouldn’t（情态动词否定式）
核心：否定目的需在从句中体现否定，而非引导词
高频考点 与目的不定式的转换（一）
转换前提：主从句的主语必须一致
转换公式：
主句+so that+主语+情态动词+动词原形
= 主句+to/in order to/so as to+动词原形
高频考点 与目的不定式的转换（二）
例句：
原句：I learn French so that I can talk with French people.
转换：I learn French to talk with French people.
转换：I learn French in order to talk with French people.
核心：转换后去掉从句主语和情态动词，直接接动词原形
小练习 句式转换
将下列句子转换为目的不定式结构
1.He exercises every day so that he can keep healthy.
2.I save money so that I can buy a new book.
He exercises every day to keep healthy.
I save money to buy a new book.
易混点辨析表格对比
结构 后接成分 语气特点
so that/in order that 完整句子（主+谓） so that口语化；in order that正式
to/in order to/so as to 动词原形 简洁通用，口语书面均可
拓展 主从句主语不一致的情况
当主从句主语不同时，不能转换为目的不定式
例句：I bought a book so that my sister can read it.
（主句主语I，从句主语my sister，不可转换）
注意：此为考试易错题，需重点区分
