2025-2026学年仁爱科普版英语九年级暑假巩固复习——状语从句

状语从句 一、 状语从句知识要点 1. 什么是状语从句？ 作用：在复合句中，修饰主句的动词、形容词、副词或整个句子，说明动作发生的时间、地点、原因、条件、目的、结果、方式、比较、让步等。 位置：可位于主句之前（通常用逗号隔开）或主句之后（通常不用逗号）。 When the bell rings, we go into the classroom. (时间，主句前) We go into the classroom when the bell rings. (时间，主句后) If it rains tomorrow, we won't go hiking. (条件，主句前) We won't go hiking if it rains tomorrow. (条件，主句后) 2. 常见状语从句类型、连接词及用法要点 类型 常用连接词 (从属连词) 作用/含义 例句 特别注意事项 1. 时间状语从句 when, while, as, before, after, since, until/till, as soon as, once, whenever 表示主句动作发生的时间 When I arrived home, it was dark. I will call you as soon as I arrive. 时态搭配关键！特别注意“主将从现”规则。 2. 条件状语从句 if, unless (= if not), as/so long as, in case 表示主句动作发生的条件 If it doesn't rain, we will have a picnic. You can't pass the exam unless you study hard. 时态搭配关键！特别注意“主将从现”、“主情从现”、“主祈从现”规则。 3. 原因状语从句 because, since, as, now that, seeing that 表示主句动作发生的原因 He was late because he missed the bus. Since/As everyone is here, let's begin. because语气最强，回答 why的提问；since/as/now that常表已知原因，语气较弱。 不能与 so 连用！ 4. 结果状语从句 so...that, such...that 表示主句动作导致的结果 The box is so heavy that I can't lift it。 It was such a hot day that nobody wanted to go out. so + adj./adv. + that； such + (a/an) + adj. + noun + that； 5. 目的状语从句 so that, in order that 表示主句动作发生的目的 We got up early so that we could catch the first bus. 从句中常含情态动词can/could, may/might, will/would。 6. 让步状语从句 although, though, even though, even if, no matter + wh-, whether...or... 表示“虽然”、“尽管”、“即使” Although/Though it was raining, they still played football. Even if it's difficult, I'll try my best. No matter what happens, don't give up. although/though/even though 不与 but 连用！ even if 强调极端让步。 no matter + wh- = wh- + ever (whatever, whenever, wherever...) 7. 比较状语从句 than, as...as, not as/so...as 表示主句和从句的动作或状态之间的比较 He runs faster than I (do). She is as tall as her sister (is). This book is not so interesting as that one. 注意比较对象一致。 than 和 as 后的从句常用省略形式（保留必要的助动词/be动词/情态动词）。 8. 地点状语从句 where, wherever 表示主句动作发生的地点 Put the book where it was. Wherever you go, I will be with you. 注意与定语从句区别（定语从句修饰名词，状语从句修饰动词）。 9. 方式状语从句 as, as if/though 表示主句动作发生的方式或状态 Do as I say. He talks as if he knew everything. as if/though 引导的从句常用虚拟语气 3. 核心时态搭配规则 (重点！) 1） 时间 & 条件状语从句中的“主将从现”： 规则：当主句表示将来发生的动作（用一般将来时 will/shall/be going to + V原或其他表示将来的形式），而时间/条件状语从句表示这个将来动作发生的时间点或条件时，从句用一般现在时代替将来时。 例： I will call you when I arrive home. (主句将来时 will call， 从句用现在时 arrive表将来时间点) If it rains tomorrow, we won't go hiking. (主句将来时won't go，从句用现在时rains表条件) She is going to visit her grandma before she leaves for Beijing. (主句将来时is going to visit，从句用现在时 leaves表将来时间点) “主情从现”：如果主句是情态动词 (can, may, must, should...) + 动词原形，从句也用一般现在时。 You can go out if you finish your homework. 主祈从现”：如果主句是祈使句，从句也用一般现在时。 Please close the window before you leave. 2）时间状语从句中的“主过从过”： 规则：当主句是过去时态时，时间状语从句通常也需用相应的过去时态（一般过去时、过去进行时、过去完成时等），以保持时态一致。 例： He was watching TV when I arrived. (主句过去进行时was watching， 从句一般过去时arrived， 表示“我到达时他正在看电视”) After he had finished his homework, he went to bed. (从句过去完成时had finished表示动作在主句动作went之前完成) 3） 其他类型状语从句：原因、结果、目的、让步、比较、地点等状语从句的时态，主要根 据从句动作实际发生的时间和主句时态来决定，没有像时间/条件状语从句那样严格的特殊规则，但要保证时态逻辑合理。 He didn't go to school because he was ill yesterday. (主句过去时，从句过去时，原因发生在过去) She works hard so that she can pass the exam. (主句现在时，从句含情态动词can，表示现在努力为了将来通过考试) 4. 重要注意事项 1）连词唯一性：在复合句中，一个连词只能引导一个从句。不能同时使用两个连词连接主句和从句。 ❌ Because he was tired, so he went to bed early. (错！用了because就不能用so) ✅ Because he was tired, he went to bed early. (对！) ✅ He was tired, so he went to bed early. (对！这是两个简单句，用so连接表因果的并列句 ) ❌ Although it was late, but they kept working. (错！用了although/though就不能用but ) ✅ Although it was late, they kept working. (对！) ✅ It was late, but they kept working. (对！) 2）区分 when & while & as： when：最常用。可指时间点（某时刻发生），也可指时间段（在那段时间里发生）。主从句动作可同时发生，也可先后发生。 while： 强调主从句动作同时发生，且通常动作持续一段时间。从句动词常用进行时态。 While I was reading, my brother was playing games. (两个持续动作同时进行) as： 常表示“一边...一边...”，强调动作同时发生、伴随进行。也可表示“当...时”，或“随着...”。 She sang as she walked along the river. (边走边唱) As time went by, he became stronger. (随着时间流逝) 3）区分 because, since, as, for： because：直接原因，语气最强。回答 why 的提问。常置于主句后。 Since / as：已知的、显而易见的原因，语气较弱。常置于主句前。 for：并列连词（不是从属连词），连接并列句。表示补充说明或推断的理由，语气最弱。不能置于句首。 二、 状语从句专项练习 (分层设计) 练习一：连词选择填空 (从括号中选择合适的连接词) 1. ________ (When/While/As) I was walking in the park, I met an old friend. 2.
