过去分词作表语和状语学案
(必修二U5 Music)
教学重点 · 作表语:表主语状态 / 感受,相当于形容词,跟系动词;-ed 表 “感到……”/ 事物状态,-ing 表 “令人……”。· 作状语:逻辑主语与句主语一致,表被动 / 完成,可表时间 / 原因等 6 种功能,可加连词;逻辑主语不一致用独立主格。· 特殊形式:having been done 仅作状语,强调动作先于谓语;done 表被动不强调先后。· 分词辨析:done 作状语表被动 / 完成,doing 表主动 / 进行。
教学难点 · -ed 与 - ing 的精准区分(人作主语接 - ing 表性格特征)。· 作状语时逻辑主语和被动关系的判定。· done 与 having been done 的用法差异。· seated/lost 等固定表语型过去分词的识记。· 连词后过去分词的状语从句省略结构运用。
一、核心语法讲解
(一)过去分词作表语
1. 定义: 过去分词(done)作表语,放在系动词之后,用来说明主语的状态、感受、特征,相当于形容词。
2. 常用系动词: be(am/is/are/was/were)、feel、look、sound、smell、taste、seem、appear、get、become、stay、keep、remain等。
3. 基本结构: 主语 + 系动词 + 过去分词(表状态)
The window is broken. 窗户是破的。(broken表状态)
I am interested in English. 我对英语感兴趣。
4. 核心用法
(1)表示主语的心理/情绪状态(人作主语居多)
常用词: 情感类:interested(感兴趣的)、excited(兴奋的)、surprised(惊讶的)、tired(疲倦的)、frightened(害怕的)
She is very tired. 她很累。
We are surprised at the news. 我们对这个消息感到惊讶。
(2)表示主语的性质、状态(物/人作主语均可)
常用词:broken, closed, locked, gone, covered, finished, married(已婚的)、dressed(穿着...的)、lost(丢失的/迷路的)、seated(就坐的)、drunk(醉的)等。
The book is lost. 这本书丢了。
The door remains closed. 门一直关着。
(3)分清“-ed”与“-ing”分词
过去分词 (-ed):表示主语“感到……”,主语通常是人;或表示事物“自身状态”。
· I feel tired.(我感到疲惫。)
· The door is locked.(门是锁着的。)
现在分词 (-ing):表示事物“令人……”,主语通常是物。
· The movie is tiring.(电影令人疲惫。)
· The news is exciting.(消息令人兴奋。)
易错点提醒:当主语是“人”时,也能接 -ing 分词。例如:He is boring.(他这人很无趣——指他令人感到无聊)。这句指的是他本身的性格特征,而不是他的感受。
He is terrifying. /He is terrified.
Please describe a dog that is frightened. /Please describe a dog that is frightening.
过去分词作状语
1. 基本概念
过去分词(done)作状语,修饰主句谓语动词,表示动作发生的时间、原因、条件、让步、方式、伴随等,相当于一个状语从句。
核心原则:过去分词作状语,其逻辑主语必须与句子主语一致,且主语与分词是被动关系(主语被……/主语处于……状态)。
2. 句法结构:
(连词)+ 过去分词,主句 If given more time, we could do it better.
主句,(连词)+ 过去分词 The teacher came in, followed by his students.
3. 过去分词作状语的6种常见功能
(1)表时间(相当于时间状语从句)
Seen from the hill, the park looks beautiful.
= When it is seen from the hill, the park looks beautiful. 从山上看,这个公园很美。
(2)表原因(相当于原因状语从句)
Born in a poor family, he couldn’t go to school.
= Because he was born in a poor family, he couldn’t go to school. 因为出生在贫困家庭,他没法上学。
(3)表条件(相当于条件状语从句)
Given more time, we could do it better.
= If we were given more time, we could do it better. 如果多给点时间,我们能做得更好。
(4)表让步(相当于让步状语从句,常带连词though/although)
Beaten by the opposite team, we didn’t lose heart.
= Though we were beaten by the opposite team, we didn’t lose heart. 虽然被对手打败,但我们没有灰心。
(5)表方式/伴随
The teacher came in, followed by his students.
= The teacher came in and was followed by his students. 老师进来了,身后跟着他的学生。
(6)表结果
The cup fell down, broken into pieces.
杯子掉了下来,摔成了碎片。
4. 可加的连词
为使逻辑更清晰,可在分词前加连词:when, while, if, though, although, unless, once 等。
例:When heated, water turns into steam. 水加热后变成水蒸气。
5. 独立主格结构(特殊情况)
当分词逻辑主语与句子主语不一致时,需在分词前加上自己的主语,构成独立主格。
结构:名词/代词 + 过去分词
例:The work finished, we went home. 工作完成后,我们回家了。
重难点辨析
过去分词 VS 现在分词作状语
- 过去分词(done):主语与动作是被动/完成关系 Seen from the top, the city is nice.(城市被看)
- 现在分词(doing):主语与动作是主动/进行关系Seeing from the top, we find the city nice.(我们主动看)
经典例句汇总
时间:Once published, this book will be popular.
原因:Tired from the walk, he fell asleep soon.
条件:Used wisely, money can bring happiness.
让步:Though wounded, he kept on fighting.
伴随:He stood there, surrounded by his friends.
过去分词的完成式:having been done(句中常有状语for a long time, many times, twice)只作状语,不作定语
- Done:被动(不强调先后)
- Having been done:强调该动作发生在谓语动词之前
- Having been told many times, he still forgot it.
