Unit 2 Volunteering-同步【语法】 so that & in order that 目的状语从句 【同步语法复习】 1、 知识点归纳 (1) 课本核心规则 so that / in order that 引导目的状语从句，描述动作的目的，意为 “以便、为了” 1. 结构公式：主句 + so that /in order that + 完整从句（主语 + 谓语） 2. 情态动词搭配（必考） · 主句现在 / 将来时态：从句常用 can / will · 主句过去时态：从句常用 could / would 3. 使用差异 · so that：日常高频，口语书面通用；非正式场合可省略 that 写作 so · in order that：更加正式，文本中使用更少；that 不可省略 4. 位置限制： · ‌in order that‌： ‌可置于句首或主句后‌，置于句首时需加逗号隔开（语气更正式） · ‌so that‌：通常只在主句后‌，极少置于句首 (2) 拓展 拓展 1：目的从句 与 不定式目的短语互换 目的从句（so that /in order that + 句子） 目的不定式（in order to /so as to /to + 动词原形） He studies hard so that he can pass the exam. He studies hard in order to pass the exam. 结构转换规则： 1. 当主句主语 = 从句主语，两种结构可以互换； 2. 若主句主语≠从句主语，只能使用 so that 从句，不能换成 to do My mum speaks slowly so that I can understand her. (错误) My mum speaks slowly to understand her.（主语不一致，错误） 拓展 2：极易混淆两组 so 结构辨析（难点易错点） 1. so that 目的状语从句：为了…… I get up early so that I can catch the bus. 2. so…that… 结果状语从句：如此…… 以至于…… I got up so late that I missed the bus. 口诀：有目的用 so that；表结果 so + 形容词 / 副词 + that 拓展 3：标点规则 so that /in order that 紧跟主句之后，前面不加逗号 （正确） I save money so that I can buy a bike. （错误） I save money, so that I can buy a bike. 2、 课本习题 (1) 课本习题C1 Q1 What is used to connect clauses in each sentence? 答：So that; so (that); in order that Q2 What modal verb is used in each sentence? 答：Could; would; could (2) 课本习题C2 1.
