Unit2+Unit3宾语从句语法精讲与练习2026-2027学年译林版英语九年级上册

宾语从句 语法精讲与专项练习 牛津译林版九年级上册 · 重点语法突破 一、宾语从句的概念 定义：在复合句中，放在主句谓语动词（或介词、形容词）后面充当宾语的从句，叫宾语从句。 结构：主句 + 引导词 + 主语 + 谓语 + 其他 例句：I think (that) he is right. 我认为他是对的。 二、三大引导词分类（核心考点） 引导词类型 具体引导词 用法说明 that类（陈述句） that that在口语/非正式文体中常省略；从句是完整陈述句 if/whether类（一般疑问句） if, whether 从句由一般疑问句变来，表"是否" 疑问词类（特殊疑问句） what, who, whom, whose, which, when, where, why, how 从句由特殊疑问句变来，引导词在从句中充当成分 1. that 引导的宾语从句 that 无实际意义，在从句中不充当句子成分，口语中常可省略。 常见动词：think, believe, hope, say, know, guess, hear, see, feel 等 例句：She said (that) she would go to Beijing. 她说她要去北京。 ⚠ 注意：当宾语从句前有并列连词and时，第二个that不能省略。 2. if / whether 引导的宾语从句 由一般疑问句变来，意为"是否"，不能省略。 常见动词：know, ask, wonder, want to know, find out 等 例句：I wonder if/whether he will come tomorrow. 我想知道他明天是否会来。 ★ 只能用 whether 的情况（高频考点）： ① 与 or not 直接连用时：I don't know whether or not he will come. ② 介词后面：It depends on whether it will rain. ③ 不定式前面：She can't decide whether to go. ④ 句首或 discuss 等动词后：We discussed whether we should hold a party. 3. 连接代词/连接副词引导的宾语从句 由特殊疑问句变来，引导词在从句中充当主语、宾语、状语等成分，不能省略。 例句：Do you know what he is doing? 你知道他在做什么吗？ Can you tell me where he lives? 你能告诉我他住在哪里吗？ 三、语序规则：陈述语序（必考点） ★ 核心规则：宾语从句中从句一律用陈述语序（主语在前，谓语在后），不管主句是陈述句还是疑问句！ 错误：Do you know where is he? 正确：Do you know where he is? 错误：I don't know what does he like. 正确：I don't know what he likes. ⚠ 特例：当疑问词在从句中作主语时，语序本身就是陈述语序，无需改动： Who is on duty today? → I don't know who is on duty today. 四、时态呼应规则 主句时态 从句时态 一般现在时 / 将来时 根据实际情况用任何时态（不受限制） 一般过去时 从句用相应的过去时态（一般过去/过去进行/过去完成/过去将来） 客观真理 / 自然现象 永远用一般现在时，不受主句时态影响 例句：He says (that) he will go to Beijing next week. （主句现在时，从句可用将来时） He said (that) he would go to Beijing the next week. （主句过去时，从句改过去将来时） The teacher told us that light travels faster than sound. （客观真理，永远用一般现在时） 五、否定转移（高频考点） 规则：当主句主语是第一人称(I/we)，谓语是 think, believe, expect, suppose 等时，从句的否定要转移到主句上来。 例句： 我认为他不对。 × I think he is not right. √ I don't think he is right. ★ 反意疑问句也要注意： I don't think he is right, is he? （反意疑问部分根据从句来定，且用肯定形式） 六、it 作形式宾语 结构：主语 + think / find / make + it + 形容词/名词 + 真正宾语（to do / that从句） 例句： I find it easy to learn English well. 我发现学好英语很容易。 We think it important that we should protect the environment. 我们认为保护环境很重要。 七、宾语从句记忆口诀 【宾语从句三要素】 宾语从句三要素，引导词、语序、时态牢记住。 that 连接陈述句，if/whether 表"是否"句。 特殊疑问词来连接，陈述语序不能变。 主句现在从句任意，主句过去从句相应变。 客观真理永不变，一般现在时挂嘴边。 think 主语是第一，否定转移到主句。 八、专项练习（中考高频考点） （一）单项选择（20题） 1. —Do you know ______ the Capital Museum? —Next Friday.
