一、when/while/as引导时间状语从句 （一）when when引导时间状语从句，从句谓语既可以是短暂性动词，也可以是延续性动词；主句、从句动作可同时发生，也可以有先后顺序。翻译：当……时；这时。 类型1：从句短暂性动词（动作先发生，主句动作紧随其后，有先后） 1.When the bell rang loudly in the hallway, all the students rushed back to their classrooms quickly and took out their textbooks. 句意：______________________________________________________________________________。 解析：rang（响起）是短暂动词，先发生；学生冲回教室是紧随其后的动作，存在时间先后。 2.When she heard the sad news about her grandma, she sat down on the chair and cried quietly for a long time. 句意：______________________________________________________________________________。 解析：heard（听见）短暂动作在前，坐下、哭泣在后。 类型2：从句延续性动词（主从句动作同步进行，同时发生） 1.When we read interesting storybooks together in the library every afternoon, we always share our ideas and talk about the wonderful plots. 句意：______________________________________________________________________________。 解析：read（阅读）延续动词，读书、交流两个动作同步进行。 2.When my grandpa waters the flowers in the small garden after breakfast, I usually stand beside him and listen to his old stories. 句意：______________________________________________________________________________。 解析：waters（浇灌）是可持续动作，浇花和听故事同时发生。 类型3：主从句均为延续动词，动作同步 When my parents prepare delicious food in the kitchen on weekends, I help them clean the table and chat about my school life. 句意：______________________________________________________________________________。 类型4：主句延续，从句短暂（突然发生，译为“这时”） We were walking along the quiet country road and enjoying the soft wind when we met a lovely little cat with white fur. 句意：______________________________________________________________________________。 翻译 1.当大雨突然落下时，操场上所有孩子立刻跑向教学楼。（短暂动词） ______________________________________________________________________________________ 2.当我们晚上一起复习英语知识点时，我们会互相提醒易错单词。（延续动词） ______________________________________________________________________________________ （二）while while引导时间状语从句，从句谓语动词只能使用延续性动词；主句与从句的动作在同一时间段同步持续发生，翻译：正当……的时候。短暂动作（buy/leave/ring/arrive等）不能用while引导从句。 场景1：主从句均为过去进行时，两件长动作同步发生 While my elder sister was practicing the piano in the living room after dinner, I was sitting beside her and taking notes of beautiful melodies I heard. 句意：______________________________________________________________________________。 解析：was practicing、was sitting 都是延续进行动作，长时间同步进行，只能用while。 场景2：从句长动作进行中，主句短暂动作插入（while从句延续） While our whole class was having a long and relaxing art class this Wednesday afternoon, a foreign teacher suddenly came into our classroom and watched our paintings quietly. 句意：______________________________________________________________________________。 解析：was having（上课，延续）作while从句谓语；主句came是短暂动作，在从句长动作期间发生。 场景3：对比两件同时进行的持续性行为 While most students were busy reviewing their lessons for the coming mid-term exam, some lazy boys were playing mobile games secretly in the back of the classroom. 句意：______________________________________________________________________________。 场景4：while放句中，表然而、可是，用来对比两种截然不同的人、事物、情况。前后时态通常保持一致。 Some students spend all their spare time reading useful books while others only play short videos every day. 句意：______________________________________________________________________________。 易错点 错误：While the bell rang, we ran out. 原因：rang铃响是短暂动词，不能用while，需改为When the bell rang... 汉译英 1.正当老师们在办公室认真批改试卷时，一群学生敲门进来请教难题。 ______________________________________________________________________________________ 2.每当奶奶坐在院子里织毛衣时，我就坐在她旁边听她讲童年故事。 ______________________________________________________________________________________ （三）as as引导时间状语从句，从句大多搭配延续性动词；主句和从句动作同步发生、交替进行，两种核心译法：一边……一边/随着。不能用于瞬间短暂动作先后发生的场景。 用法1：一边……一边（两个动作同步交替进行） 1.As she walked slowly along the quiet river and enjoyed the soft sunset wind, she kept singing the gentle old songs that her mother taught her years ago. 句意：______________________________________________________________________________。 解析：walked、sing均为可持续动作，同步交替，用as最佳。 2.As my grandfather drinks a cup of hot tea after each meal, he talks about his interesting life experiences when he was young. 句意：______________________________________________________________________________。 用法2：随着（时间、环境慢慢变化） 1.As the cold winter passes and warm spring comes

grow older day by day, we gradually understand our parents’ hard work and deep love hidden behind their strict words. 句意：______________________________________________________________________________。 拓展（同步对比场景） As most students write down their notes carefully in class, some look around and think about the fun activities after school.

1.她一边骑车穿过林间小路，一边欣赏路边的野花。 ______________________________________________________________________________________ 2.随着时间流逝，我们之间珍贵的友谊变得更加牢固。 ______________________________________________________________________________________ 二、until&till用法对比 肯定句 主句延续动词，动作持续到该时间，可用before替换。 I waited until 9 p.m.我一直等到晚上九点。 否定句 not…until 直到……才，动词短暂/延续均可。 He didn’t go to bed until his dad came back.直到爸爸回来他才睡觉。 区别 1.until可放句首、用于until when问句；till不能放句首。 Until you help me, I can’t finish it.在你帮我之前，我完不成它。 —Until when will you stay here?—Until Friday.—你要待到什么时候？—待到周五。 2.Not until句首倒装Not until+从句，主句部分倒装。 Not until he left did I realize the truth.直到他离开，我才知道真相。 It is not until…that 强调句型强调直到某个时间才…… It was not until midnight that I fell

The building was ancient, with tall wooden shelves and the scent of aged paper lingering in the air. Most visitors came during the day, but Lily preferred the quiet hours before closing. One evening, as she was organizing books in the history section, she heard a faint whisper. She turned around, but no one was there. Assuming it was her imagination, she continued working. However, the whispers grew louder, forming words: “Seek the hidden truth.” Curious and a bit frightened, Lily followed the sound to a shelf filled with old, dusty books. One book, bound in dark leather without a title, seemed to emit a soft glow. She opened it and found handwritten notes between the printed lines, detailing a secret room beneath the library. Determined to uncover the mystery, Lily searched the library's floor and discovered a loose tile(瓷砖). Beneath it was a small key. Using clues from the book, she found a hidden door behind a bookshelf. The key fit perfectly. Inside, she found a room filled with ancient manuscripts and artifacts. Among them was a letter addressed to her. It read: “Knowledge is a treasure, but the key to understanding lies in curiosity. Welcome, Guardian of secrets.” Task 1 Answer the questions 1.

A 【导语】本文围绕“睡眠是健康的必需项”展开，介绍了青少年睡眠不足的常见诱因、睡眠对身心的修复作用、改善睡眠质量的实用方法，点明优质睡眠对记忆力、情绪状态、在校表现的积极意义，呼吁青少年保证每日充足睡眠。 1. 句意：睡眠对我们的健康至关重要，就像食用健康食物、规律锻炼一样。 A. do 动词原形，做；B. doing 动名词/现在分词，做；C. does 动词第三人称单数形式，做。 本句中like是介词，后接动名词作宾语，and连接并列的对等结构，需和前面的动名词eating形式保持一致，因此用doing。故选B。 2. 句意：然而很多青少年因为作业、游戏或是其他原因，无法获得充足睡眠。 A. other 形容词，其他的，后接可数名词复数；B. others 代词，其他的人/物，后面不能再接名词；C. another 代词/形容词，另一个（三者及以上范围），后接可数名词单数。 空后是复数名词reasons，需要形容词修饰，others无法修饰名词，another仅能接单数名词，因此用other。故选A。 3. 句意：我们睡觉时，身体和大脑会自我休整恢复，为第二天做好准备。 A. lose 丢失、失去；B. save 拯救、节约；C. recharge 休整、恢复精力、充电。 根据睡眠的作用可知，睡觉时身心是在恢复储备精力，lose、save不符合睡眠的功能描述，recharge贴合语境。故选C。 4. 句意：缺乏充足睡眠的话，我们可能会觉得疲惫、健忘，甚至生病。 A. fall 动词原形，进入（某种状态），落下；B. fell 动词过去式，摔倒；C. falling 现在分词/动名词。 情态动词may后需要接动词原形，和前面的动词原形feel构成并列谓语，且fall sick是固定搭配，意为“生病”，符合语义。故选A。 5. 句意：专家建议青少年每晚需要8-10小时的睡眠来保持健康。 A. health 名词，健康；B. healthy 形容词，健康的；C. unhealthy 形容词，不健康的。 stay表示“保持某种状态”时是系动词，后接形容词作表语；结合语境，睡够8-10小时的目的是保持健康，unhealthy语义相反，health是名词无法作表语，因此选healthy。故选B。 6. 句意：为了睡得更好，睡前要避免使用手机、平板，因为电子设备发出的蓝光会让你保持清醒。 A. because 因为，表原因；B. so 所以，表结果；C. but 但是，表转折。 前文是给出的睡眠建议，后文是解释这个建议的原因，属于前果后因的逻辑，用because引导原因状语从句，so、but不符合逻辑关系。故选A。 7. 句意：你可以试试读一本书，或是听令人放松的音乐。 A. loud 大声的；B. relaxing 令人放松的；C. noisy 吵闹的。 本句介绍的是睡前助眠的活动，大声、吵闹的音乐会影响睡眠，只有放松的音乐符合语境。故选B。 8. 句意：同时，每天固定时间上床睡觉，能帮你的身体养成健康的习惯。 A. habit 习惯；B. hobby 爱好；C. plan 计划。 develop a healthy habit是固定搭配，意为“养成健康习惯”，固定作息属于长期养成的生活习惯，不是爱好也不是短期计划。故选A。 9. 句意：优质睡眠能提升记忆力、改善情绪，还能让你在学校有更好的表现。 A. worse 更差的；B. better 更好的；C. bad 糟糕的。 本句讲的是好睡眠的益处，和动词improve（提升、改善）对应，应该是带来更好的在校表现，worse语义相反，bad是原级不符合“改善后”的比较逻辑。故选B。 10. 句意：所以如果你想要保持活力、注意力集中，一定要保证每晚获得充足的睡眠！ A. get 动词原形，获得；B. got 动词过去式，获得；C. getting 现在分词/动名词。 make sure后接宾语从句，从句是给出的日常建议，用一般现在时，主语是you，谓语动词用原形，get enough sleep是固定搭配，意为“获得充足睡眠”。故选A。 读后续写 Read the passage and complete the tasks(根据短文内容完成任务) Every Friday afternoon,13-year-old Lily volunteered at the town's old library. The building was ancient, with tall wooden shelves and the scent of aged paper lingering in the air. Most visitors came during the day, but Lily preferred the quiet hours before closing. One evening, as she was organizing books in the history section, she heard a faint whisper. She turned around, but no one was there. Assuming it was her imagination, she continued working. However, the whispers grew louder, forming words: “Seek the hidden truth.” Curious and a bit frightened, Lily followed the sound to a shelf filled with old, dusty books. One book, bound in dark leather without a title, seemed to emit a soft glow. She opened it and found handwritten notes between the printed lines, detailing a secret room beneath the library. Determined to uncover the mystery, Lily searched the library's floor and discovered a loose tile(瓷砖). Beneath it was a small key. Using clues from the book, she found a hidden door behind a bookshelf. The key fit perfectly. Inside, she found a room filled with ancient manuscripts and artifacts. Among them was a letter addressed to her. It read: “Knowledge is a treasure, but the key to understanding lies in curiosity. Welcome, Guardian of secrets.” Task 1 Answer the questions 1.
