Unit 3 语法讲义——目的状语从句、结果状语从句 2026-2027学年外研版英语九年级上册

九年级上册 Unit 3 目的状语从句与结果状语从句 第一部分  目的状语从句 定义：如果从句表示的是主句行为的目的，该从句就是目的状语从句。 引导词：so that；in order that 含义：为了，以便于 结构：主句 + so that / in order that + 目的从句 注意：从句里常搭配情态动词：can, could, may, might, will, would。 （一）so that 与 in order that 的用法 so that 最常用，口语、书面都可以，可放主句后；不能直接加动词原形，后面接完整句子。 例句：He gets up early so that he can catch the early bus．他早起，为了能赶上早班车。 in order that 偏正式，比 so that 语气强，同样后面接句子。 例句：She studies hard in order that she may pass the exam．她努力学习，为了可以通过考试。 （二）同义转换 so that / in order that + 从句  ⇨  in order to do / to do（不定式表目的） He gets up early so that he can catch the early bus． ＝ He gets up in order to catch the early bus． ＝ He gets up to catch the early bus． ❌ 否定目的：so that … not ＝ in order that … not（为了不……）＝ in order not to do。 Turn down the radio so that you won’t disturb him．＝ Turn down the radio in order not to disturb him． ⚠️ 易错点 错：I study hard so that to get good grades． ✅ 正确：I study hard in order to get good grades． 解析：so that 后面必须是完整从句，不能直接加 to do。 时态呼应：主句过去时，从句情态动词换成过去式 could / might / would。 He spoke slowly so that we could understand him．（can → could） 标点：so that / in order that 放在主句后面，前面不加逗号； 如果从句前置：In order that he could catch the bus, he got up early．这时后面加逗号。 第二部分  结果状语从句 引导词：so … that；such … that 含义：如此……以至于……，表示主句造成的结果。 （一）关于 so 的句型 句型 1：so + 形容词 / 副词 + that 从句 so + 形容词：She is so tired that she can’t walk．她如此累，走不动了。 so + 副词：He runs so fast that nobody can catch him．他跑得如此快，没人追得上。 句型 2：so + adj. + a/an + 单数名词 + that 从句 注意：名词必须是单数可数名词，冠词 a/an 不能丢。 例：It was so cold a day that we stayed at home．天气太冷，我们待在家里。＝ such a cold day that… 句型 3：so + many / much / few / little + 名词 + that … 当名词前有 many, much, few, little（表数量少），只能用 so，不用 such。 so many + 可数名词复数：There are so many people that I can’t see the stage．人太多，我看不见舞台。 so much + 不可数名词：He has so much work that he can’t go out．他工作太多，没法出门。 so few + 可数名词复数：There are so few students that the class is quiet．学生太少，教室里很安静。 so little + 不可数名词：There is so little water that we can’t drink．水太少，不够我们喝。 ⚠️ 区分：little 表示“小”时，用 such，不用 so：such little children 这么小的孩子。 （二）so … that 的否定结构 so…that 否定句：so … that … not … 如此……以至于不能…… 可以同义替换为 too…to…（太……而不能）或 not…enough to…（不够……去做）。 He is so young that he can’t go to school．＝ He is too young to go to school．＝ He isn’t old enough to go to school． （三）关于 such 的句型 such + 名词短语 + that 从句 句型 1：such + a/an + adj. + 可数名词单数It is such a good book that I read it twice．这是一本如此好的书，我读了两遍。 句型 2：such + adj. + 可数名词复数They are such interesting stories that we love them．这些故事如此有趣，我们很喜欢。 句型 3：such + adj. + 不可数名词It is such bad weather that we have to stay home．天气太差，我们只能待在家。 ⭐ 重难点 so…that 与 such…that 的区分：看中心词。 中心词是形容词 / 副词 → 用 so；中心词是名词 → 用 such。 例：so beautiful a girl ＝ such a beautiful girl She is so beautiful a girl that everyone likes her． ＝ She is such a beautiful girl that everyone likes her． ⚠️ 易错点 混淆 so that（目的）和 so … that（结果）： ① He speaks slowly so that we can understand him．他说慢一点，为了让我们听懂（目的）。 ② He speaks so slowly that we all fall asleep．他说话如此慢，我们都睡着了（结果）。 📝 课堂练习题 一、基础题：用 so that / so … that / such … that 填空 1.
