2026年中考英语从句复习复习讲义
一、状语从句 (Adverbial Clauses)
核心功能：修饰整个句子（表时间、原因、条件等），相当于一个“副词”。
记忆口诀：先看时态，再看逻辑，主将从现。
1 时间状语
常用引导词：when, while, before, after, as soon as, since
核心考点 & 易错点：
① since + 过去时，主句 + 现在完成时
例句：He has lived here since he came to Changsha.
② while 后面通常接进行时
例句：My mother was cooking while I was doing my homework.
2 条件状语
常用引导词：if (如果), unless (除非 = if...not)
核心考点 & 易错点：
① 主将从现：主句将来时，从句现在时
例句：We will go hiking if it is fine tomorrow.
② unless 不能和 not 连用
例句：You will miss the bus unless you hurry up.
3 原因状语
常用引导词：because, since, as
核心考点 & 易错点：
① because 回答 Why
例句：—Why didn’t you come —Because I was ill.
② since 表示“既然”，语气较弱
例句：Since everyone is here, let’s start.
4 让步状语
常用引导词：although/though (虽然), even if (即使)
核心考点 & 易错点：
致命陷阱：后面不能加 but！
例句：Although he is old, he runs very fast.
5 目的/结果状语
常用引导词：so that (为了/以便), such...that
核心考点 & 易错点：
① so that 接从句，to 接动词原形
例句：I get up early so that I can catch the first bus.
② such + (a/an)+adj+n+that
例句：It is such a good movie that I want to watch it again.
二、宾语从句 (Object Clauses)
核心功能：在句子中充当宾语，通常跟在动词或介词后。
三要素口诀：语序、时态、引导词。
1 语序 (Word Order)
必须用陈述语序 (主语+谓语)。
例句：Could you tell me where the hospital is
2 时态 (Tense)
① 主现从任意：主句是现在时，从句根据实际情况用任何时态。
例句：I know that he will come tomorrow.
② 主过从过完：主句是过去时，从句用过去的某种时态。
例句：He said that he wanted to visit Hunan.
③ 特例：从句表述客观真理，永远用一般现在时。
例句：The teacher told us that the earth goes around the sun.
3 引导词 (Connector)
① 陈述句 → that (可省略)
例句：I think (that) you are right.
② 一般疑问句 → if / whether (是否)
例句：I wonder if he will join us.
③ 特殊疑问句 → 特殊疑问词 (what, who, how等)
例句：Please tell me how I can get to the station.
三、定语从句 (Attributive Clauses)
核心功能：修饰名词或代词（先行词），相当于一个“形容词”。
核心难点：关系代词的选择。
1 核心关系词用法
① 先行词指人：who / that
例句：The boy who is playing basketball is my brother.
② 先行词指物：which / that
例句：The book which I bought yesterday is very useful.
③ 表所属：whose
例句：I know the girl whose father is a doctor.
2 必考雷区 (只用 that 的情况)
当先行词被以下词修饰时，只能用 that，不能用 which：
① 最高级
例句：This is the best film that I have ever seen.
② 序数词
例句：The first thing that I want to do is to rest.
③ 不定代词
例句：Is there anything that I can do for you
④ 人+物并列
例句：We talked about the people and places that we visited.
四、其他从句 (高频补遗)
1 主语从句 (Subject Clauses)
① 位置：放在句首，或用 it 做形式主语。
② 例句：It is important that we learn English well.
2 表语从句 (Predicative Clauses)
① 位置：放在 be 动词之后。
② 例句：My question is when we will have the exam.
③ 例句：The reason is that he got up late.
解题技巧
1 还原法：先找主谓宾，去掉从句，句子立刻简单。
2 代入法：定语从句把选项代回先行词，看是否通顺。
3 时态呼应：看到从句先想时态是否匹配、是否主将从现。
