2027高考英语一轮复习-主语从句专练 主语从句专练-夯实基础 考点讲解 一、引导词辨析 引导词分三大类，判断顺序：先看缺不缺成分 → 再看句意 1. that 从句主谓结构完整、句意确定无疑问，that无词义、不作成分，仅起连接 必考陷阱：句首主语从句，that绝对不能省略！（宾语从句that可省，这是最常对比挖坑点） 例：That we should value honesty is important. 2. whether 从句完整、语义表“是否” 铁律：主语从句（句首）只能用whether，不能用if！ 拓展：it作形式主语后置时，偶尔可用if；有or not时，只能用whether 例：Whether the plan will work remains unknown. 3. 连接代词：what / who / whom / whose / which / whatever / whoever 从句缺主语 / 宾语 / 表语 / 定语时选用 王者考点：what = the thing(s) that，最常考（区分that vs what：缺成分→what；不缺成分→that） 例：What he did surprised everyone.（did缺宾语） 4. 连接副词：when / where / why / how 从句主谓完整，但缺时间/地点/原因/方式状语 例：How we balance study and rest matters a lot. 二、it 作形式主语 真正主语从句后置，it 放在主句当假主语，写作、语法填空都常考，务必背4大类固定模板： 1. It is + 形容词 + that从句 It is clear / obvious / true / important / necessary / strange that… 特殊：important/necessary/strange 后从句常用虚拟 (should) do 2. It is + 名词短语 + that从句 It is a pity / a fact / common knowledge / no wonder that… 3. It is + 过去分词 + that从句 It is said / reported / believed / suggested / announced that…（据说/据报道/人们认为） 4. It + 不及物动词 + that从句 It seems / appears / happens / occurred to sb. that…（某人突然想到…） 【what引导的主语从句，一般不使用it作形式主语】 三、主谓一致 单个主语从句作主语，主句谓语动词一般用单数 例：What we need is more patience. 【what从句指代多个不同事物时，谓语可用复数】 四、高频易错陷阱 1. 句首主语从句漏写 that（对比宾从that可省） 2. 句首表“是否”误用 if → 只能whether 3. 分不清 that / what：从句缺成分硬填that 4. no matter what / no matter who 不能引导主语从句！（只能引导让步状语从句；名词性从句用whatever / whoever） 5. 和定语从句混淆：what不能引导定语从句；that不能在名词性从句中充当主宾 5、 标准做题步骤 1. 识别：从句在主句主语位置 → 判定主语从句 2. 拆分：划出从句，看从句内部是否缺主/宾/表 ◦ 缺名词性成分 → what/who/which… ◦ 不缺成分 → 下一步看句意 3. 判语义： ◦ 陈述事实、无疑问 → that ◦ 表“是否” → whether ◦ 缺状语（何时/何地/为何/如何）→ when/where/why/how 4. 检查特殊规则：句首不能用if、句首that不可省略 专项训练 1. ________ he will come to our party is certain. 2.
