The castle's gates are locked by 3 grammar spells. Only correct participles can open them! Follow us! Let's learn the magic rules step by step! 4 The guards only let those who know what makes us different from verbs in. Elves decorate the castle. Decorating elves smile. Verb indicates action and tense, while participle serves as a descriptive label without tense. This difference allows us to explore how participles function as descriptive tools in sentences. 第一层：城堡入口·分词的“身份识别” 二、知识点讲解与闯关 5 第一层：城堡入口·分词的“身份识别” 二、知识点讲解与闯关 ① 现在分词（doing）= 主动+进行 ② 过去分词（done）= 被动+完成 the crying baby the broken key 6 第一层：城堡入口·分词的“身份识别” 二、知识点讲解与闯关 ①“The ______ (paint) wall looks new.” ②“The ______ (shine) sun lights up the garden.” painted shining Participles don't have tenses—they describe! 7 The torches, portraits and magic ball in the Magic Gallery are all out of order due to the word segmentation function! Let's fix them by mastering participles' roles! 第二层：魔法长廊·分词的“多样功能” 二、知识点讲解与闯关 This news is exciting. People are excited about traveling. “-ing分词（如exciting ）表事物性质，意为‘令人…’ 在句中做表语；-ed分词（如excited ）表人物状态，意为‘感到…’ ，在句中作宾语补足语。 8 第二层：魔法长廊·分词的“多样功能” 二、知识点讲解与闯关 What to fill in？Let's think about it. The film is _________ (interest). We are _________ (interest) in it. interesting interested This set of fill-in-the-blank illustrates the core difference when participles are used as predicatives: present participles are mostly used to describe things, while past participles are mostly used to describe people. 9 第二层：魔法长廊·分词的“多样功能” 二、知识点讲解与闯关 The house built there is mine. 单个分词作定语通常前置，像“sleeping ”修饰“girl” ；分词短语作定语通常后置，如“built there ”修饰“house ” ，用于描绘名词的特征或动作关系 。 The sleeping girl is Carry. 10 第二层：魔法长廊·分词的“多样功能” 二、知识点讲解与闯关 The ______ (fall) leaves dance in the wind. The path ______ (cover) with leaves looks beautiful. falling covered This set of fill-in-the-blanks shows the typical difference in usage between present participle (indicating active/ongoing) and past participle (indicating passive/completed) as attributive. 11 第二层：魔法长廊·分词的“多样功能” 二、知识点讲解与闯关 I found her lying on the grass. 当分词和宾语是主动关系，用现在分词；是被动关系，用过去分词 ，补充说明宾语的动作或状态 。 They considered this work finished. 12 第二层：魔法长廊·分词的“多样功能” 二、知识点讲解与闯关 We saw the thief ______ (run) away and later saw him ______ (catch) by the police. running caught This set of fill-in-the-blank shows the difference in the use of present participle (active/ongoing) and past participle (passive/completed) as complement of object. Participles work as predicative, attribute and object complement! 13 “The final spell needs the right logic: Who does the action? 第三层：塔顶书房·分词的“逻辑魔法” 二、知识点讲解与闯关 “The final spell needs the right logic: Who does the action? ______ (Climb) the tower, we see the town. 分词作状语时，需明确其动作的发出者或承受者——即“逻辑主语”，且逻辑主语通常与主句的主语一致 ______ (Invite) by the elves, we enter the tower. Climbing Invited 14 第三层：塔顶书房·分词的“逻辑魔法” 二、知识点讲解与闯关 Having finished the housework, Mina went on to watch TV. When using participles as adverbials, the logical subject is typically the same as the main clause's subject. To determine whether the logical subject and participle action are "active relationship" or "passive relationship", along with the sequence of actions, one can identify whether to use present participle (active/ongoing), past participle (passive), or the present participle perfect form (where the action precedes the main clause). 15 第三层：塔顶书房·分词的“逻辑魔法” 二、知识点讲解与闯关 ①错误句：Walking in the garden, a snake scared me. ②正确句：Walking in the garden, I was scared by a snake. 16 第三层：塔顶书房·分词的“逻辑魔法” 二、知识点讲解与闯关 ______________(Prepare) for 3 days, the party started. Having prepared “筹备”这一动作发生在主句动作“started（开始）”之前，且是主动筹备，因此需用现在分词的完成式 “Having prepared”，强调分词动作先于主句动作完成。若动作早于主句动作发生，且表主动，要用“having done”结构。 Participles share the same doer with the main clause when working as adverbial! 17 1. 终极任务：修复城堡庆典的核心咒语 三、巩固挑战 The party news is ______ (excite). We all feel ______ (excite). 第一空修饰事物 “the party news”（派对消息），用现在分词 exciting，表 “令人兴奋的”，符合 “-ing 分词作表语多描述事物本身具有的特质” 规则； 第二空描述人 “we”（我们）的感受，用过去分词 excited，表 “感到兴奋的”，符合 “-ed 分词作表语多说明人的主观感受” 规则。 exciting excited （1）作表语 【AI评估】: 90% 正确:exciting; excited 10% 错误:第一空填 excited，第二空填 exciting 18 1. 终极任务：修复城堡庆典的核心咒语 三、巩固挑战 Look at the ______ (dance) girl under the tree. The girl ______ (dance) there is my classmate. 第一空是单个分词作前置定语，修饰 “girl”（女孩），“girl” 与 “dance” 是主动关系（女孩跳舞），用现在分词 dancing（正在跳舞的）； 第二空是分词短语作后置定语，同样 “girl” 与 “dance” 是主动关系（女孩在那里跳舞），仍用现在分词 dancing，符合 “分词作定语时，主动关系用现在分词，且短语需后置” 规则。 dancing dancing （2）作定语 【AI评估】: 80% 正确:dancing;dancing 20% 错误:第二空填 decorated(混淆主动关系) 19 1. 终极任务：修复城堡庆典的核心咒语 三、巩固挑战 ______ (Walk) slowly, we enjoy the castle views. ______ (Invite) warmly, we join the party happily. 第一空逻辑主语是主句主语 “we”（我们），“we” 与 “walk” 是主动关系（我们走路），用现在分词 Walking 作伴随状语，符合 “主动关系用现在分词作状语” 规则； 第二空逻辑主语是 “we”，“we” 与 “invite” 是被动关系（我们被邀请），用过去分词 Invited 作原因状语，符合 “被动关系用过去分词作状语” 规则。 Walking Invited （3）作状语 【AI评估】: 70% 正确:Walking; Invited 30% 错误:第二空填 Inviting 20 1. 终极任务：修复城堡庆典的核心咒语 三、巩固挑战 We found the hall ________ (decorate) beautifully. The host saw us ________ (enter) the hall. 第一空 “hall”（大厅）与 “decorate”（装饰）是被动关系（大厅被装饰），用过去分词 decorated 作宾补，符合 “被动关系用过去分词作宾补” 规则； 第二空 “us”（我们）与 “enter”（进入）是主动关系（我们进入），且 “saw” 强调动作正在发生，用现在分词 entering 作宾补，符合 “主动且进行的动作，用现在分词作宾补” 规则。 decorated entering （4）作宾补 【AI评估】: 60%正确:decorated;entering 40% 错误:第一空填 decorating Participles work as predicative, attribute and object complement! Participles don't have tenses—they describe! Participles share the same doer with the main clause when working as adverbial! 21 You've mastered participle magic! You've mastered participle magic! 22 四、结尾升华 Present "-ing" for things' trait, past "-ed" for feelings straight. （表语：事物特质用-ing，情感感受用-ed） Active actions take "-ing" form, passive state with "-ed" form. （定语：主动动作-ing描，被动状态-ed绕） Running, moving—adverbials "how" unfold; Invited, loved— passive "why" told. （状语：主动-ing表方式，被动-ed释由来） To objects: "-ing" shows what's in play, "-ed" marks what has found its way. （宾补：-ing表动作进行，-ed表已然完成） In sentences, they spread around, making sense where words are bound. （应用：分词遍布句间，让语义更连贯） PARTI（participle）藏头诗 23 五、HOMEWORK 1.
