专题25：句法之名詞性从句
核
【核心知识·深度解读】
名词性从句（主语从句、宾语从句、表语从句、同位语从句）是高考英语
语法填空、短文改错及书面表达的高频考点，重点考查连接词的选择、陈述
语序、形式主语/宾语、同位语从句与定语从句的区别等。近年命题更注重在
复杂语境中考查从句的逻辑关系与语义衔接，尤其关注科技、文化、社会热
点等话题中的从句应用。本专题包含核心知识精讲、15 道单句填空、10 道句
子翻译与表达及 3 篇语法填空篇章练习，帮助学生系统掌握名词性从句的用
法。
教学目标
1. 知识目标：掌握名词性从句的四种类型及连接词用法；2. 能力目标：
能在语法填空和写作中正确运用名词性从句；3. 素养目标：通过语境理解从
句在语篇中的表意功能。
教学重难点
重点：that/whether/what 的选择；难点：同位语从句与定语从句的区分、
it 作形式主语的灵活运用。
第一课时 · 诊断与突破
环节一：课前诊断（3 分钟）—— 找准学生真实问题设计意图： 用 3 道典型题快速检测学生前备知识，暴露常见错误，为精
讲提供依据。
1. ________ we need is more time. (what/that)
2. I wonder ________ he will come tomorrow. (whether/if/that)
3. The news ________ our team won excited everyone. (that/which)
预设错误及对策： 第 1 题错填 that → 强调“what 在从句中作宾语”；
第 2 题错填 that → 强调“wonder 表示疑问，不能用 that”；第 3 题错填
which → 强调“同位语从句用 that，且 that 不作成分”。
环节二：考点精讲（20 分钟）—— 结合高考真题，说透规则
考点 1：that 引导的名词性从句（主语/宾语/表语/同位语）
【 高 考 真 题 】 It is estimated that the project will cost $10
million. (2022 全国乙卷)
【规则总结】that 在从句中不作成分，无词义。主语从句句首 that 不可省；
同位语从句 that 不可省；宾语从句 that 常可省（并列宾语从句第二 that 不
省）。
考点 2：whether 与 if 的选择
【高考真题】The question is whether the technology is ready for
widespread use. (2023 新高考Ⅰ卷)
【规则总结】主语从句、表语从句、同位语从句、介词后用 whether；
whether 可与 or not 连用，if 一般不直接连用。
考点 3：what 引导的名词性从句【高考真题】What matters most is not the result but the process.
(2024 九省联考)
【规则总结】what 在从句中作主语/宾语/表语，意为“所……的（事物）”。
考点 4：同位语从句 vs 定语从句（学生最难区分）
【对比讲解】The news that he told me was false.（定语从句，that 作
told 的宾语）
The news that our team won was exciting.（同位语从句，
that 不作成分，解释 news 内容）

第二课时 · 易错突破与综合提升
环节五：错题归因（10 分钟）—— 聚焦三大高频错点
错点 1：what 与 that 混淆
【错误案例】That we need is more time.（错）→ What we need is
more time.（正）
【原因分析】that 在从句中不作成分，而这里 we need 缺宾语，所以用
what。
【巩固练习】________ you said at the meeting was very inspiring.
(What)
错点 2：whether 与 if 误用
【错误案例】If he will come is uncertain.（错）→ Whether he
will come is uncertain.（正）
【原因分析】主语从句不能用 if。
【巩固练习】It depends on ________ he is ready. (whether)
错点 3：同位语从句与定语从句混淆
【错误案例】The news which our team won excited us.（错）→ The
news that our team won excited us.（正）【原因分析】同位语从句解释 news 的内容，从句完整，用 that。
【巩固 练习】 The fact ________ he failed the exam surprised us.
(that)
