单元语法精讲精练 (Grammar Focus) 语法精讲 一、连词（状语从句引导词）核心精讲 用法类型 核心功能 常见结构 / 搭配 易错点提醒 although（让步状语从句） 表 “虽然 / 尽管”，引导让步状语从句，表达转折关系，相当于 though 1. 基本结构：Although/Though + 从句，主句Although you argued, you are still very close friends.2. 可与 but 转换，但不能同时使用Although he is tired, he keeps working. = He is tired, but he keeps working. 1. although/though 不可与 but 连用：句中用了 although/though，就不能再用 but，二者只能选其一2. 位置灵活：可放句首（从句在前，主句在后），也可放句中（主句在前，从句在后）3. 语气差异：although 比 though 更正式，书面语更常用 until（时间状语从句） 表 “直到…… 为止”，引导时间状语从句，强调动作持续到某个时间点 1. 肯定句：主句动词为延续性动词，表 “动作持续到……”I will wait for you until you come back.2. 否定句：not…until… 表 “直到…… 才……”，主句动词多为短暂性动词You won't know how he feels until you talk to him. 1. 延续性 vs 短暂性动词：肯定句中主句动词必须是延续性的（如 wait, work, stay），短暂性动词（如 leave, finish）不能直接用于 until 引导的肯定句2. not…until… 句型的倒装 / 强调：Only until…/ It is not until…that… 结构中需注意语序变化（初中阶段重点掌握基础用法）3. 不要混淆 till 和 until：二者用法基本一致，until 可放句首，till 通常不用于句首 so that（目的状语从句） 表 “为了 / 以便”，引导目的状语从句，说明主句动作的目的 1. 基本结构：主句 + so that + 从句（从句常含 can/could/will/would 等情态动词）You can write to your parents so that they'll know how you feel.2. 可与 in order that 互换，口语中更常用 so that 1. 区分 so that 与 so…that…：so that 表 “目的”，so…that… 表 “结果（如此…… 以至于……）”，二者结构不同2. 从句常含情态动词：so that 引导的目的状语从句，多搭配 can/could/will 等，表 “为了能够……”3. 不要省略 that：口语中有时会省略，但书面语中建议保留，避免歧义 2、 本单元语法核心考点速记 1. 状语从句引导词答题技巧 引导词 关键词信号 解题判断逻辑 although 句子存在明显转折关系（“虽然…… 但是……”） 先看是否有 but，有 but 就不能选 although；无 but 且表让步，选 although until 句子含 “直到……”“直到…… 才……” 含义，或出现延续性 / 短暂性动词 肯定句看主句动词是否延续；否定句（won't/can't/don't…）优先考虑 not…until… so that 句子表 “目的 / 为了……”，从句含 can/will 等情态动词 区分 “目的” 和 “结果”，表 “为了达成某个目的” 时用 so that if 句子表 “假设 / 条件”，主句含 will/should/can 等 遵循 “主将从现”，从句用一般现在时，主句用将来 / 情态 / 祈使句 2. 易混引导词对比速记 结构 含义 核心区别 例句 although / though 虽然，尽管 引导让步状语从句，不能与 but 连用 Although he is young, he knows a lot. but 但是 并列连词，连接两个并列句，表转折 He is young, but he knows a lot. so that 为了，以便 引导目的状语从句，表动作目的 She studies hard so that she can pass the exam. so…that… 如此…… 以至于…… 引导结果状语从句，表动作结果 She studied so hard that she passed the exam easily. if（条件） 如果 引导条件状语从句，遵循主将从现 If you work hard, you will succeed. if（宾语从句） 是否 引导宾语从句，时态随主句变化 I don't know if he will come. 补充：单元重点短语拓展（语法配套） 1.on purpose：故意地（介词短语，作状语） 2.cut…in half：把…… 切成两半；减少一半 3.put oneself in one's shoes：设身处地为某人着想 4.shut oneself away：把自己封闭起来；与世隔绝 5.plenty of：大量的，充足的（后接可数 / 不可数名词） 语法精练 一、单项选择。 ()1.________ it rained, they still played football on the playground.
