Unit2 On the money语法讲解与练习 时间状语从句、地点状语从句详细讲解 课本原句引入 1. When the tin is ready, put all the money that you have into it.（时间状语从句） 2. Now let’s get back where we started — the dream tins.（地点状语从句） 学习重点：时态规则、引导词辨析、语序标点、易混句型区分 第一部分 时间状语从句 一、基本定义 在复合句中,用来修饰主句、说明主句动作发生或持续的时间的从句,叫做时间状语从句。 本单元必考引导词：when, while, as soon as, before, after, until, since 所有时间状语从句通用核心规则：描述将来动作时，一律主将从现、主情从现、主祈从现 二、七大引导词精讲 1. when 当……时候（最通用、考频最高） ✅ 用法：可接短暂性动词（瞬间完成）或延续性动词（持续进行），既可指时间点，也可指时间段。 ✅ 三种时态搭配（完全适配本单元） （1）主祈从现（课本重点句型） When +从句（一般现在时），主句（祈使句） When you finish saving money, use it to achieve your dream. 当你存完钱时，用它去实现你的梦想。 （2）主将从现 You will feel proud when you finish your saving plan. 当你完成储蓄计划，你会感到自豪。 （3）主过从过（描述过去发生的动作） Kira felt confused when she knew more money brought more trouble. 当基拉知道钱多麻烦也多时，她感到很困惑。 2. while 在……期间 ✅ 核心限制（超级易错）：while后面只能接延续性动词（stay, wait, save, study等），不能接瞬间动词（finish, arrive, stop等） ✅ 含义：强调主句动作在从句动作持续的过程中发生 ✅ 常用时态：主过进+从过进（两个动作同时持续进行） My parents were working while I was saving pocket money. 我存零花钱的时候，父母一直在工作。 ⚠️ 极简区分：when万能用，while只持续 3. as soon as 一……就…… ✅ 含义：强调两个动作紧密衔接、立刻发生 ✅ 时态：将来场景严格遵守主将从现 I will put money into the tin as soon as I get my pocket money. 我一拿到零花钱就放进存钱罐里。 4. before 在……之前 ✅ 可直译“在……之前”，也可意译“……之后才……” You should think carefully before you spend your money.你花钱之前要仔细考虑。 5. after 在……之后 ✅ 表动作先后顺序，从句动作先完成，主句动作后发生 After you finish your saving goal, you can buy what you want. 完成储蓄目标后，你可以买自己想要的东西。 6. until / till 直到……为止 ✅ 两大核心结构（中考必考句型） （1）肯定句：主句延续性动词 + until 直到……（动作持续到某时） I will save money until the end of the year. 我会存钱一直到年底。 （2）否定句：not...until 直到……才……（高频考点） I didn’t understand the meaning of saving until I grew up. 我直到长大才懂得储蓄的意义。 7. since 自从……以来 ✅ 时态固定搭配：since+一般过去时，主句现在完成时 I have saved much money since I started my dream tin. 自从我开启梦想存钱罐计划，已经存了很多钱。 三、时间状语从句语序与标点规则 1. 从句前置：引导词+从句，主句 (👉 从句和主句之间必须加逗号) When the tin is ready, put your money in it. 2. 从句后置：主句+引导词+从句 (👉 不加逗号) Put your money in the tin when it is ready. 四、高频易错点汇总 1. 将来场景从句绝对不用will，只用一般现在时 ❌ When I will get money, I will save it. ✅ When I get money, I will save it. 2. while不能接短暂动词（finish, arrive, leave等） 3. since句型主句必用现在完成时 4. not...until 翻译固定为“直到……才”，不要直译 第二部分 地点状语从句（单元重点难点） 一、基本定义 用来修饰主句动作、说明动作发生或存在的地点、位置的从句,叫做地点状语从句。 单元核心引导词：where（必考）；拓展：wherever（无论哪里） 二、where 详细用法 ✅ 含义：在……的地方 ✅ 功能：限定主句动作发生的具体位置,不指代具体某个地点名词,侧重位置场景 ✅ 课本原句精讲 Now let’s get back where we started. 译文：现在我们回到我们最初开始的地方。 ✅ 拓展例句 Put your dream tin where you can see it every day. 把你的梦想存钱罐放在你每天都能看到的地方。 I will go where there are more chances to learn about money management. 我会去有更多理财学习机会的地方。 三、wherever 拓展用法 ✅ 含义：无论哪里 = no matter where ✅ 用法：引导让步性地点状语从句 Wherever you go, you should keep the habit of saving. 无论你去哪里，都要保持储蓄的习惯。 四、语序、时态与标点规则 1. 语序灵活：可前置、可后置 Where you work hard, you will get gains.（前置，加逗号） You will get gains where you work hard.（后置，无逗号） 2. 时态规则：无时态特殊限制,跟随主句时态统一即可,将来场景同样遵循主将从现 五、超级易混难点：where状语从句 VS where定语从句 很多同学丢分的核心！一句话区分：看前面有没有地点名词 1. 地点状语从句：where前无地点名词，表动作发生的位置场景 Put the tin where it is safe.（前面无place/room等名词，状语从句） 2. 定语从句：where前有地点名词，用来修饰前面的名词 This is the place where I started to save money.（前面有place，定语从句） 第三部分 两大状语从句 终极对比总结 从句类型 核心引导词 核心作用 时态特点 时间状语从句 when/while/as soon as/before/after/until/since 说明动作发生的时间 将来场景必遵主将从现；since专属现完 地点状语从句 where/wherever 说明动作发生的位置 时态随主句,无特殊固定规则 第四部分 必考易错口诀 1. 时间从句表将来，主将从现不能忘； 2. while只接延续动，when通用不用慌； 3. not until译为“直到才”，since配现完是常态； 4. where无词是状语，有词修饰是定语； 5. 从句句首加逗号，句尾紧跟不用留。 配套练习 一、用所给单词的正确形式填空 根据时间/地点状语从句时态规则、主谓一致填写正确形式 1.
