宾语从句讲解+练习2026-2027学年人教版九年级上册英语

九年级英语Unit3+Unit4宾语从句专题讲义 第一部分 知识点精讲 一、什么是宾语从句 在复合句中，由一个句子充当另一个句子的宾语，这个句子就叫作宾语从句。宾语从句通常跟在及物动词（如 think, believe, know, wonder, find 等）或介词后面，使表达的内容更丰富、更完整。 简单句：We know him.（him 作宾语） 复合句：We know (that) he likes English.（he likes English 作宾语） 二、引导词 1. that 引导的宾语从句——陈述句作宾语 当宾语从句来源于一个陈述句时，用连词 that 引导。that 在从句中不作任何成分，也没有任何具体意思，因此在口语或非正式文体中常省略。 课本原文例句（人教版九年级 Unit 3 Section A Grammar Focus） ： · I believe (that) reading is important for learning. · I think (that) the best way is to do maths problems. · Peter finds (that) he can connect physics with something in real life.  that 不可省略的情况： · 在并列宾语从句中，第二个 that 不可省略：He said (that) he liked maths and that he wanted to be a maths teacher. · 当 that 从句是双宾语中的直接宾语时：Ella tells me that this sentence is correct in English. 2. if / whether 引导的宾语从句——一般疑问句作宾语 当宾语从句来源于一个一般疑问句时，用 if 或 whether 引导，意为“是否”。if 和 whether 在从句中不充当任何成分，但不可省略，它们是区分从句是陈述还是疑问的关键标志。 课本原文例句： · I wonder if / whether you could help me. · I want to know if / whether you read English books outside class. 只用 whether 不用 if 的三种情况： 情况 例句 在介词后面 I'm thinking of whether we should go to see the film. 与 or not 直接连用 I don't know whether or not they can get there on time. 在不定式（to do）前面 I can't decide whether to go or stay. 3. 特殊疑问词引导的宾语从句——特殊疑问句作宾语 当宾语从句来源于一个特殊疑问句时，由连接代词（who, whom, whose, which, what）和连接副词（where, how, why, when）引导。这些连词既有词义，又在从句中充当句子成分，不能省略。 · Do you know whose book it is?（谁的，作定语） · Could you tell me why the train is late?（为什么，作状语） · He asked who could answer the question.（谁，作主语） 三、语序——一律用陈述语序 无论主句是陈述句还是疑问句，也无论引导词是什么，宾语从句一律用陈述语序，即“引导词 + 主语 + 谓语 + 其他”。 原句（疑问语序） 改为宾语从句（陈述语序） Who is Jim waiting for? I wonder who Jim is waiting for. Can Lily carry the basket? I wonder whether/if Lily can carry the basket. Where did Anna go yesterday? I wonder where Anna went yesterday. 注意：一般疑问句和特殊疑问句改为宾语从句时，be 动词、情态动词要放到从句主语之后；助动词 do/does/did 应删去，谓语动词根据实际情况变为相应时态。 四、时态——主从句的呼应规则 宾语从句的时态受主句时态的影响，遵循以下三条规则： 规则一：主现从不限 主句是一般现在时（或现在进行时、现在完成时），宾语从句可根据需要选用任何一种时态。 · I know (that) you are a teacher.（现在） · I know (that) you were a teacher one year ago.（过去） · I know (that) you will be a teacher next year.（将来） 规则二：主过从过 主句是一般过去时，宾语从句必须用相应的过去时态（一般过去时、过去进行时、过去将来时、过去完成时）。 · He heard you had a bad cold. · He said he had been to Shanghai before. 规则三：真理从现 当宾语从句表示客观真理、自然现象或名言时，从句一律用一般现在时，不受主句时态限制。 · Our teacher told us that the earth moves around the sun. · Dad told me that the sun rises in the east. 五、难点拓展：否定转移 当主句主语是 I，谓语动词是 think, believe, expect, guess, suppose 等表示“认为、猜测”意义的动词时，若宾语从句要表达否定意义，否定词应转移到主句谓语上，从句谓语用肯定形式。 · 正确：I don’t think we have met.（我想我们没见过面吧。） · 错误：I think we haven’t met. 第二部分 练习题巩固 一、单项选择 1. （课本 Unit 3 拓展） I believe ______ reading is important for learning.
