2026届高考英语语法-连词专题复习学案

2026高考高三英语二轮连词专题复习

一、高考核心知识点梳理 

（一）连词两大核心类别（高考必考）

核心定义：连词是连接单词、短语、分句或句子的词，本身不充当句子成分，只表逻辑关系。

1. 并列连词

功能：连接并列关系的词、短语或分句，分为联合、转折、选择、因果四类。

◆联合类：and（和）、both...and...（两者都）、not only...but also...（不仅……而且……）、as well as（也）

◆转折类：but（但是）、yet（然而）、while（而，表对比）

◆ 选择类：or（或者；否则）、either...or...（要么……要么……）、neither...nor...（既不……也不……）

◆ 因果类：so（因此）、for（因为，表补充说明）

高考真题例句（2025·新课标I卷改编）：Not only does she excel in academics, but also she takes an active part in volunteer work.

2. 从属连词

功能：引导名词性从句或状语从句，连接主句与从句，表主从关系。

◆引导状语从句：

时间状语：when（当……时）、while（在……期间）、since（自从）、until（直到）、as soon as（一……就……）

条件状语：if（如果）、unless（除非）、as long as（只要）

让步状语：though/although（虽然）、even if/though（即使）、while（尽管）

原因状语：because（因为）、as（由于）、since（既然）

目的状语：so that（以便）、in order that（为了）

高考真题例句（状语从句·2024·全国卷II改编）：

Although the task was challenging, we managed to complete it ahead of schedule。

◆ 引导名词性从句：that（无词义）、whether/if（是否）、wh-系列连接词（what/who/which等）

高考真题例句（名词性从句·2024·新课标II卷改编）：

The key finding of the study was that when crowds were further divided into smaller groups, the averages from these groups were more accurate。

（二）连词三大高频考点变形（高考重难点）

1. 并列连词的主谓一致规则

结构：neither...nor.../either...or.../not only...but also...连接主语时，谓语动词遵循就近原则；both...and...连接主语时，谓语动词用复数。

真题原型（2023·新课标卷I）：Neither the teacher nor the students are in favor of the plan。

2. 从属连词的状语从句省略

结构：当状语从句的主语与主句主语一致，且从句含be动词时，可省略从句主语和be动词。

真题原型（2025·浙江卷）：When (he was) asked about his dream, he said he wanted to be a scientist。

3. 连词与易混词的区分

◆ because（连词，接从句）vs because of（介词短语，接名词/代词/动名词）

◆ though（连词，接从句）vs despite/in spite of（介词/短语，接名词/代词/动名词）

真题原型（2024·天津卷）：He failed the exam because he was careless, not because of bad luck。

（三）连词的逻辑关系判定（2025模拟新增考点）

1. 并列句中，根据分句间语义判断连词类型：转折关系用but/yet，因果关系用so/for，选择关系用or。

2. 主从句中，根据从句功能判断连词：表条件用if/unless，表让步用though/although，表目的用so that。

二、高考高频考点与易错点突破

 （一）高频考点清单（近5年考查频次）

◆ 并列连词与主谓一致：每年必考，涉及语法填空、单选题型。

◆ 从属连词引导状语从句：每年必考，涉及语法填空、短文改错题型。

◆ 连词与介词短语的辨析（because/because of等）：4考，涉及语法填空、单选题型。

◆ 连词的省略与替代：3考，涉及语篇填空、书面表达题型。

（二）易错点辨析（丢分重灾区）

1. 并列连词while/but/however的区别

◆ but：表转折，连接并列分句，不可用逗号与句子隔开；

◆ while：表对比或让步，对比时前后分句语义相反，让步时可置于句首；

◆ however：表转折，是副词，需用逗号与句子隔开，可置于句首、句中或句末。

例句对比：

✔ He is poor, but he is happy。

✔ While he is poor, he is happy。

✔ He is poor; however, he is happy。

2. 从属连词because/since/as的区别

◆ because：表直接原因，语气最强，可用于回答why提问，可用于强调句；

◆ since/as：表已知或显而易见的原因，语气较弱，不可用于强调句。

例句对比：

✔ —Why are you late? —Because I missed the bus。

✔ Since everyone is here, let's start the meeting。

3. 连词使用的冗余错误

常见错误：though/although与but连用；because与so连用；if与or else连用。

改错真题（2024·模拟改编）：

错误：Although he is young, but he is very experienced。

改正：去掉but

三、解题技巧（高考快速得分法）

1. 并列连词判定技巧：看句子是否为并列结构，分句间无主次之分，再根据逻辑关系（转折/因果/选择）确定具体连词。

2. 从属连词判定技巧：先判断从句类型（状语从句/名词性从句），再根据从句功能（时间/条件/让步）匹配连词，同时注意从句的时态规则（如时间状语从句用一般现在时表将来）。

3. 短文改错连词错误判定技巧：看到though与but、because与so连用，直接标记删除其中一个；看到while/however混用，根据标点和位置判断修改。
