Unit5 Music speaks 核心语法精练 （原因状语从句） 目录 二、考点夯基 3 一、单项选择 3 二、完成句子 3 三、句型转换 4 一、语法填空 5 二、完型填空 5 一、知识回顾 本单元语法核心为原因的表达，围绕“如何说明动作发生的原因”展开，分为两大核心体系：连词引导的原因状语从句（后接完整句子）与介词短语表原因（后接名词/代词/动名词）。二者语义相近但语法结构完全不同，是初中英语语法的高频考点，也是写作中丰富句式的核心工具。 一、原因状语从句——从属连词与并列连词 1. 基本定义 原因状语从句用于说明主句动作、状态或事件发生的原因或理由，是状语从句的重要类型，通常由从属连词引导，从句为结构完整的句子。本单元重点学习4个表原因的连词：because, since, as, for，四者语气强度、使用位置、语法功能存在明显差异。 2. 分连词详解 （1）because —— 表直接原因，语气最强 语气与功能：四个连词中语气最强，用于说明动作发生的直接、根本、明确的原因，是造成结果的核心因素。专门用于回答 `why` 提出的问句。 句子位置：从句可放在主句之前（常用逗号隔开），也可放在主句之后，位置灵活。 特殊用法：在强调句型 `It is/was...that...` 中，若强调原因状语，只能用 `because`，不能用 since / as / for。 易错提醒：汉语中习惯说“因为……所以……”，但英语中 `because` 和 `so` 不能同时出现在同一个句子中，二者只能保留其一。 例句（贴合单元音乐主题）： ① I love this piece of light music because it has a calming effect. 我喜欢这首轻音乐，因为它有令人平静的效果。 ② Because he practised the guitar day and night, he played wonderfully at the concert. 因为他日夜练习吉他，他在音乐会上演奏得非常精彩。 ③ It is because of his talent for music that he became a famous composer. 正是因为他的音乐天赋，他才成为了著名的作曲家。 （2）since —— 表已知原因，语气较强 语气与功能：语气弱于because，强于as。用于说明说话双方都知晓、显而易见的原因，常译为“既然、鉴于”，带有“理由已经成立，由此推论”的意味，不用于回答why问句。 句子位置：从句通常放在主句之前，更符合表达逻辑。 例句： ① Since you have a good voice, why not try out for the school singing competition? 既然你嗓音很好，为什么不参加学校的歌唱比赛呢？ ② Since the ticket was expensive, we decided not to go to the jazz concert. 既然票价很贵，我们决定不去爵士音乐会了。 （3）as —— 表附带原因，语气较弱 语气与功能：语气最弱，最口语化。用于说明非常明显、无需强调的附带原因，常译为“由于、鉴于”，原因的重要性很低，只是顺带提及。 句子位置：从句多放于句首，也可置于主句中。 例句： ① As the bell rang, all the students stopped talking and waited for the teacher. 由于铃响了，所有学生都停止说话，等待老师。 ② As she loves music very much, she spends most of her pocket money on CDs. 她非常喜欢音乐，所以把大部分零花钱都花在了唱片上。 （4）for —— 表补充/推断原因，并列连词 语法属性：for 是并列连词，而非从属连词，因此它引导的不是原因状语从句，而是并列句，对前一分句进行补充说明。 语气与功能：语气最弱，仅用于补充说明理由，或根据前文现象进行推断，不能用于回答why问句。 句子位置：只能放在主句之后，必须用逗号与前面的主句隔开。绝对不能放在句首。 例句： ① The hall was full of people, for the famous pianist was giving a show that night. 大厅里挤满了人，因为那位著名的钢琴家当晚有演出。（补充说明人多的原因） ② He must be a talented musician, for he can play so many instruments. 他肯定是个有天赋的音乐家，因为他会演奏这么多种乐器。（由“会多种乐器”推断“有天赋”） 3. 四大连词核心对比表 连词 语气强度 语法属性 位置 核心功能 能否回答why 例句 because 最强 从属连词 主句前 / 后 说明直接、根本原因 能 I cried because the song was so touching. 我哭了，因为这首歌太感人了。 since 较强 从属连词 多放主句前 说明已知、显而易见的原因 不能 Since you like music, you should learn an instrument. 既然你喜欢音乐，你该学门乐器。 as 较弱 从属连词 多放主句前 说明附带、明显的原因 不能 As it was late, we ended the party early. 由于很晚了，我们早早结束了派对。 for 最弱 并列连词 只能放主句后 补充说明或推断理由 不能 He went to bed early, for he had a concert the next day. 他早睡了，因为第二天有音乐会。 规律总结 强调直接原因、回答为什么 → 用 because 理由已知、译为“既然” → 用 since 顺带提及、口语化表达 → 用 as 补充说明、句中推断 → 用 for 二、介词短语表原因 除了连词引导从句，英语中还常用介词短语表达原因，后接名词、代词、动名词或名词性短语，不能接完整句子。本单元核心掌握 `because of`，同时拓展常见的 `thanks to`、`due to`、`as a result of`。 1. because of —— 最核心考点 结构属性：短语介词，意为“因为、由于”，语义和 `because` 完全一致。 用法规则：后接名词、代词、动名词（doing）或名词性从句，不能直接接主谓完整的句子。 同义转换：`because + 句子` = `because of + 名词/动名词`，二者可自由转换，是句型转换题的高频考点。 例句： ① She missed the concert because of the heavy rain. = She missed the concert because it rained heavily. 她因为大雨错过了音乐会。 ② He won first prize because of his hard practice. = He won first prize because he practised hard. 他因为刻苦练习得了一等奖。 2. 其他常见表原因的介词短语 （1）thanks to 意为“多亏、由于”，通常带有褒义，表示“多亏了某因素才有好结果”；偶尔也可用于反语，表讽刺。 例句：Thanks to the support of my family, I could attend the music summer camp. 多亏了家人的支持，我才能参加音乐夏令营。 （2）due to 意为“由于、因为”，语气更正式，常在句中作表语或状语。 例句：The success of the concert was due to the efforts of all the performers. 音乐会的成功归功于所有表演者的努力。 （3）as a result of 意为“作为……的结果；由于”，强调前因带来的后果。 例句：As a result of the virus, many live concerts were cancelled. 由于病毒，很多现场演唱会被取消了。 三、核心考点：because 与 because of 的辨析与转换 二者是考试的高频易错点，核心区别在于词性不同，后接成分不同。 类别 词性 后接成分 句型转换示例 because 连词 完整的句子（主语 + 谓语 + 其他） The music sounds nice because it has a gentle tune. because of 介词短语 名词、代词、动名词 The music sounds nice because of its gentle tune. 转换方法 1. because of 转 because：在because of后的名词/动名词前加主语，把名词/动名词改成相应的动词形式，构成完整句子。 2. because 转 because of：去掉because从句的主语，把谓语动词改成名词/动名词形式，接在because of后。 易错警示 ❌ 错误：Because he was ill, so he didn’t come to school. ✅ 正确：Because he was ill, he didn’t come to school. / He didn’t come to school because he was ill. 原因：because 和 so 都是连词，一个句子中不能同时出现两个连词引导从句，二者只能保留一个。 一、单项选择 1.

He didn't attend the meeting yesterday because it was rainy.（改为同义句，每空一词） He didn't attend the meeting yesterday ______ ______ the rain. 【答案】because of 【解析】because是连词，后接完整的句子；because of是短语介词，后接名词、代词或动名词。空格后the rain是名词短语，因此用because of表原因，二者语义完全一致，可进行同义转换。 2. As you are very familiar with this pop song, you can sing along to the music.（改为用since引导的同义句） ______ ______ ______ very familiar with this pop song, you can sing along to the music. 【答案】Since you are 【解析】as和since都可引导原因状语从句，用于说明显而易见、双方已知的原因，常译为“既然”，二者在此处用法相近可互换。句首单词首字母需大写，从句结构保持不变。 3. The violinist gave a wonderful performance because of her skilled bow control.（改为含because的复合句） The violinist gave a wonderful performance ______ ______ ______ skilled at bow control. 【答案】because she was 【解析】because of后接名词短语，改为because引导的原因状语从句时，需补充完整的主谓结构。此处指代女性小提琴家，用she作主语；be skilled at是固定搭配，意为“擅长……”，时态为一般过去时，be动词用was。 4. Since it was Saturday, he didn't have to go to school.（改为用for补充说明的同义句，每空一词） He didn't have to go to school, ______ it was Saturday. 【答案】for 【解析】for是并列连词，只能位于主句之后，用逗号与主句隔开，用于补充说明主句的理由或对主句内容进行推断，符合题目“补充说明”的用法要求。 5. We had to stay in the hotel because of the heavy rain.（改为含because的复合句） We had to stay in the hotel ______ ______ ______ ______ heavily. 【答案】because it was raining 【解析】because of后接名词短语the heavy rain，改为because引导的原因状语从句时，需转换为完整的句子结构。用it指代天气，时态用过去进行时was raining体现当时的状态，副词heavily修饰动词rain，表示“雨下得很大”，与原句语义一致。 一、完形填空 Imagine you are in a boat far out at sea.
