Day 28：状语从句 (2)：原因 (because)/让步 (although)/结果 (so that) 从句
一、原因状语从句
核心逻辑：解释动作发生的理由。
1. 常用引导词辨析
虽然都翻译成“因为/由于”，但在语气强弱和用法上有显著区别：
-
引导词 语气强弱 核心用法 典型例句
because 最强 回答 Why 的提问；表示直接、未知的理由。 — Why are you late
— Because I missed the bus.
since 居中 意为“既然”。侧重已知的、显而易见的事实。 Since everyone is here, let's start. (既然人
都到了……)
as 最弱 意为“由于”。通常放在句首，理由是附带说明。 As it is raining, we have to stay at home.
-
2. 中考常考陷阱（重点！）
陷阱一: “Because” 与 “So” 不共戴天
规则： 英语中，连词 because（原因）和 so（结果）不能同时出现在一个句子里。只能二选一。
(×) Because he was ill, so he didn't go to school.
(√) Because he was ill, he didn't go to school.
(√) He was ill, so he didn't go to school.
陷阱二: Because (连词) vs. Because of (介词短语)
公式：
Because + 句子 (主语+谓语...)
Because of + 名词 / 代词 / 动名词 (doing)
例: He didn't come because he was ill. (接句子)
例: He didn't come because of his illness. (接名词)
二、 让步状语从句 (Adverbial Clauses of Concession)
核心逻辑：表示“虽然……但是……”，即结果出乎意料，存在转折。
1. 核心引导词
although / though: 意为“虽然，尽管”。
Although 较正式，放在句首多；though 较口语化，可放在句中甚至句末。
even if / even though: 意为“即使，纵然”。语气更强，往往假设某种极端情况。
2. 中考常考陷阱
陷阱: “Although” 与 “But” 不共戴天
第 74 页 共 85 页
规则： 英语中，although/though 不能与 but 连用。但可以与 yet (可是) 或 still (仍然) 连用。
(×) Although he is old, but he runs fast.
(√) Although he is old, he runs fast.
(√) He is old, but he runs fast.
三、 结果与目的状语从句
核心逻辑：引出动作导致的结果或动作的目的。中考常将 so...that (结果) 与 so that (目的/结果) 混淆考查。
1. 结果状语从句：so ... that ... / such ... that ...
意为“如此……以至于……”。
A.公式区别（必背）：
①so + adj. / adv + that ... 例：The box is so heavy that I can't lift it.
②such +a/an +adj + Noun + that ... 例：It is such a heavy box that I can't lift it.
B.特殊情况（难点）：
当名词前有多/少修饰时（many, much, few, little），必须用 so，不用 such。
例：There are so many people in the park that I can't find you. (不能用 such many)
2. 目的状语从句：so that / in order that
意为“为了，以便”。
通常从句中会含有情态动词 (can, could, may, might)。
例: Speak clearly so that they can understand you. (为了他们能听懂)
3. 句型转换（同义句替换）
这是中考句型转换题的高频考点：
so ... that ... (否定) = too ... to ... (太……而不能……)
例：He is so young that he can't go to school.
= He is too young to go to school.
so ... that ... (肯定) = ... enough to ... (足够……去做……)
例：The box is so light that I can carry it.
= The box is light enough for me to carry.
四、重点总结与记忆技巧
1. 记忆口诀
原因因为（Because）不加所以（So），虽然（Although）但是（But）互不理。
So 后形容或副词，Such 后头跟名词。多多少少（many/much/few/little）都用 So，结果目的要分清。
2. 易错点
①词性判断： 看到 rain 要反应过来是名词还是动词。
例：because it rained heavily (句子)
例：because of the heavy rain (名词短语)
②So vs Such： 看到 weather（不可数名词），不要受中文干扰用 a lovely weather，而是 such lovely weather。
③To 不定式转换： 在 too...to 结构中，如果主语不一致，记得加 for sb.；如果动词是不及物动词，记得加介词。
