Unit3 Never give up语法状语从句讲解与练习 时间状语从句完整精讲 一、基础定义 在复合句中充当时间状语的从句叫时间状语从句，由时间连词引导，用来表示主句动作发生的时间。 1.主将从现：主句将来时/情态动词 /祈使句 → 从句用一般现在时 2.主过从过：主句为过去时态，从句统一使用对应过去时态 3.since 专属：从句一般过去时，主句现在完成时 二、第一组：before /after/when /while 1. before 在…… 之前 含义：主句动作发生在从句动作之前 例句： You should try again before you decide to give up. 在你决定放弃之前，你应该再试一次。 He had practiced thousands of times before he got the chance. 在得到机会前，他已经练习了上千次。 2. after 在…… 之后 含义：从句动作完成后，主句动作才发生 例句： After he recovered from the injury, he returned to training. 康复之后，他重新投入训练。 I will share my experience after I finish the speech. 我演讲结束后就分享我的经历。 3. when 当…… 时 核心特点：从句谓语短暂性、延续性动词都可以用，既可指时间点，也可指时间段 两种常用场景： 1 短暂动作：when + 瞬间动词（arrive, see, stop） When he heard the news, he didn’t lose heart. 当他听到这个消息，他没有灰心。 ② 进行时态搭配（突然发生）：was/were doing…when…did I was training hard when a serious accident happened. 我正在刻苦训练时，一场严重事故发生了。 4. while 在…… 期间；正当…… 时 核心限制：从句谓语只能是延续性动词，多用进行时，强调两段动作同步持续进行 例句： While his teammates were resting, he kept running alone. 队友休息的时候，他独自坚持跑步。 While facing difficulties, he never chooses to give up. 补充：when/while 省略结构（高频难点） 主从句主语一致，且从句含be动词，可省略主语+be动词， 变为when/while +doing 原句：While he was training, he wrote down his problems. 省略：While training, he wrote down his problems. 训练时，他记下自己遇到的难题。 格式注意: 连词放句首时，从句末尾必须加逗号；放句中无需逗号。 When you meet trouble, never give up.（句首,逗号） Never give up when you meet trouble.（句中，无逗号） 三、第二组：since /till/until 1. since 自从…… 以来 时态固定搭配：从句一般过去时，主句现在完成时 含义：动作从过去某一刻持续到现在 例句： He has never given up since he failed his first match. 自从第一场比赛失利，他就从未放弃。 I have admired the athlete since I watched his story. 自从看完他的故事，我一直敬佩这位运动员。 2. till & until 直到…… 为止 *相同点：肯定句中大多可互换，主句用延续性动词，动作持续到从句时间停止 I will wait till/until the coach finishes talking. 我会等到教练说完话。 *区别：till 偏口语，不能放句首；until 正式，句首、句中都能用 ✅ Until you succeed, you can’t stop trying.（句首只用 until） ❌ Till you succeed, you can’t stop trying. *重点结构：not…until/till 直到…… 才 主句用短暂性动词 + 否定，表示从句动作发生后主句动作才启动 I didn’t realize the importance of persistence until I failed many times. 直到多次失败，我才明白坚持的重要性。 四、第三组：as soon as /whenever 1. as soon as 一…… 就…… 强调从句动作一结束，主句动作立刻发生，严格遵循主将从现 例句： As soon as he gets the training plan, he will start to practice. 他一拿到训练计划就开始练习。 As soon as the rain stopped, they went on running. 雨一停，他们就继续跑步。 2. whenever 每当；无论何时 同义替换：every time，引导重复发生的场景 Whenever he feels upset, he reads encouraging books. 每当他感到沮丧，他就读励志书籍。 You can ask me for help whenever you meet difficulties. 无论何时你遇到困难，都可以找我帮忙。 五、易混连词对比（中考区分考点） 1. when vs while *when：动词不限，可表瞬间动作；可用于 when…did（突然） *while：只能延续动词，只表同步持续动作，常搭配进行时 例： When the bell rang, we were training.（rang 瞬间动词，不用 while） While we were training, the bell rang.（were training 延续，可用 while） 2. till vs until 句首只用 until；否定结构 not…until 二者通用。 3. after vs before before：主句动作在前；after：从句动作在前。 六、单元主题综合例句（贴合 Unit3 Never give up） 1.Before you want to give up, think about all your efforts. 想要放弃前，想想你付出的所有努力。 2.While others gave up, he stuck to his dream. 当其他人都放弃时，他坚守自己的梦想。 3.He has kept training since he was refused by the team. 自从被球队拒绝，他一直坚持训练。 4.He won’t stop practicing until he achieves his goal. 不达目标，他绝不停止训练。 5.As soon as he recovers, he will return to the playground. 他一康复，就回到训练场。 6.Whenever he meets failures, he tells himself never to give up. 每当遭遇失败，他都告诉自己永不放弃。 【巩固练习】 1、 用合适连词填空 可选连词：before, after, when, while, since, until, till, as soon as, whenever） 1.I won’t stop fighting ______ I make my dream come true. 2.He has kept practicing every day ______ he lost the competition last year. 3.Think twice ______ you decide to give up your hard-won chance. 4.______ other players were resting, he kept training on the playground. 5.I will send you a message ______ I finish today’s training tasks. 6.______ he meets difficulties, he tells himself to hold on. 7.He burst into tears ______ he knew he won the important match. 8.Please wait here ______ the coach comes back to talk with you. 9.We had learned lots of skills ______ we joined the city sports team. 10.______ the heavy rain stopped, they continued their long-distance running at once. 11.I didn’t understand the power of persistence ______ I failed dozens of times. 12.She takes notes carefully ______ she listens to the speech about persistence. 13.The young athlete never gave up ______ he was refused many times. 14.______ you feel tired and upset, you can talk to your teammates. 15.The runner kept moving forward ______ he fell down from tiredness. 二、单项选择 1.I will stick to training ______ I get the chance to take part in the national game.
