四川成都高一年级英语上学期课时作业 (外研版必修一 Unit 2 Period 2(Using language 构词法 Word formation) 【应用场景】本课时作业适用于四川省成都市高一年级上学期学生,使用外研版《英语》(新标准)必修第一册 Unit 2 Exploring English;本课时作业为 Period 2(Using language · 构词法 word formation)的课后分层作业,承接 Period 1 对"英语的趣味性与创造性"的感知,进入"理解规律、学会推理"的学习。 一、作品基础信息 项目 填写内容 作业名称 外研版必修一 Unit 2 课时作业 Period 2(Using language · 构词法) 学段学科 高中英语 适用年级 高一上学期(成都地区) 教材版本 外研版《英语》(新标准)必修第一册(2019 年 7 月) 对应内容 Unit 2 Exploring English · Period 2(Using language ·Word formation) 作业类型 课时作业 完成时长 总时长 60 分钟 设计者 杨自强(四川省成都市玉林中学) 二、设计背景与意图 (一)课标与教材分析 课标要求:本作业对标《普通高中英语课程标准(2017年版2025年修订)》:主题语境为"人与自我——生活与学习(语言学习的规律、方法)"(课标表 2 子主题 5);落实语言能力、文化意识、思维品质、学习能力四项核心素养,对应学业质量水平一。构词法属于"语言知识——词汇知识"中的"构词法常识",引导学生从"依赖词典逐词死记"转向"依据规律主动推测",是新课标倡导的学习能力的重要组成。 教材地位:本课时对应 Unit 2 Using language 板块的 Review: word formation(教材第 22—23 页,Activity 1—3)。它是单元"语言现象探究"主线中承上启下的一环:Period 1 让学生感知英语的趣味性与创造性,本课时则进一步回答"这种趣味背后是否有规律可循"。教材以"例句匹配—规则归纳—语篇巩固"三步,把零散的词汇现象上升为系统的构词法知识。 【What主题语境与内容信息】 ① 主题语境(thematic context):本课属"人与自我——语言学习的规律、方法"的核心板块,承接 Period 1 的"英语充满创造力"大观念,进入"理解规则"的第二站。编者不再停留于"现象的有趣",而要引导学生发现"现象背后的规律"。 ② 语篇内容信息(content information):构成本课时的两大活动链—— Activity 1(发现式):呈现 4 个来自阅读篇的例句,覆盖 4 种构词法类型——复合(pineapple、penfriend)、派生·前缀(un- / in-:unhappy、incorrect)、派生·后缀(-ment / -ness:improvement、uniqueness)、转化(calm adj.→v.、rain n.→v.); Activity 2(巩固式):一篇约 130 词的说明性短文,要求学生在 9 个空中填入构词法术语与例词,从"输入"过渡到"输出",完成"感知—归纳—运用"的闭环。 【Why主题意义(传递意图与价值取向)】 ① 写作意图(writer's intention):编者的核心意图是帮助学生完成"零散记忆 → 系统理解"的认知跃迁。构词法不是为讲规则而讲规则,而是赋予学生一把"拆词的钥匙",让他们从此不必逐词死记硬背。教材通过 Activity 1 的"先猜后讲"与 Activity 2 的"在语篇中运用",把"英语的趣味性与创造性"从感性体验升级为可操作的方法。 ② 价值取向与立德树人(values & education): - 学习能力:从"依赖词典"转向"主动推测",培育终身学习的底层能力——这是最具迁移价值的核心素养; - 思维品质:通过比较与分类(如区分"前缀改变意义 / 后缀改变词性"),锻炼分析与归纳思维; - 文化意识:理解英语构词法背后的历史渊源(如大量借用法语、拉丁词根),感受语言作为文化载体的厚度; - 情感态度:当学生发现"原来英语是可以推理的"时,焦虑感显著下降、自信心上升——这是从"怕英语"到"敢推理"的关键转折。 【How语篇组织特征】 ① 体裁(text type):本课时为语法聚焦板块(Grammar Focus),以"例句呈现 + 规则归纳 + 语篇巩固"为编排逻辑;Activity 2 内的短文是说明性文本(expository),向学生介绍构词法知识。 ② 篇章结构(organization):采用"例句感知 → 规则归纳 → 语篇运用"的三段式。Activity 1 是发现式(学生先匹配例句与类型,教师再揭示规律);Activity 2 是巩固式(在语篇中运用规则填空)。这种"先猜后讲"的顺序符合归纳法教学理念,比"先讲后练"更利于深度学习。 ③ 语言特征(language features): - 时态运用:以一般现在时为主(陈述客观规则),辅以少量一般过去时(介绍构词法的历史来源); - 元语言(metalanguage):高频使用构词法术语(compound / prefix / suffix / conversion / abbreviation),是本课的核心词汇网; - 衔接手段:使用"For example""if…"等逻辑连接,结构清晰; - 典型例词:unhappy / improvement / uniqueness / pineapple 等,既是规则示例,又是学生必须掌握的高频词,实现"学规则 + 扩词汇"的双重收益。 教学重难点:重点:四种主要构词法(复合、派生[前缀/后缀]、转化、缩写)的识别与运用,以及单元核心词的词性转换。难点:在语篇中依据构词法规律推断生词含义,并理解构词法如何体现英语的趣味性与创造性。 (二)学情分析 维度 具体描述 已有基础 初中接触过 un- / dis- 等前缀与 -er / -ness 等后缀;认识 pineapple、homework 等复合词;对"拍照 photo"等词性转换有模糊语感 现有困惑 前缀后缀易混(尤其 in- 与 un- 的分工);"转化"概念陌生(名词动用);面对长词不会拆解,仍习惯逐词查询 差异分析 分层设置(基础/提高/拓展);基础档保底派生与复合,提高档回到教材语篇内化,拓展档完成开放性微写作,由浅入深 (三)设计意图 本课时作业以"感知—理解—辨析"为线索,按标准题型分层命制:先以单句与语篇填空夯实构词双基(派生、复合、缩写),再以教材原短文填空回到本课时语篇内化规律,最后以"构词法辨析改错"考察规则的深度运用与迁移。答案解析逐块给出"考查目标—分析—答案",便于自查与批改,落实"教—学—评"一致。 三、作业目标 目标维度 编号 具体目标 对应核心素养 评价证据 知识理解 1 能识别并运用英语四种主要构词法(复合、派生[前缀/后缀]、转化、缩写),将单元核心词按构词法规律进行词性转换与派生 语言能力 单句与语篇填空中构词正确率≥80% 能力运用 2 能在教材语篇中依据构词法知识猜测、推断生词含义,并举例说明构词如何体现英语的趣味性与创造性 语言能力、思维品质 课文语篇填空准确,并能举例说明至少 1 个构词现象 思维发展、情感态度 3 能体会构词法背后的规律与理据,认识到英语是可以推理的活的语言,增强主动推测而非死记硬背的策略意识 思维品质学习能力 微写作中能运用构词法规律解释或自创 1 个英语表达,并表达个人见解 四、作业内容与目标对应表 题号 题型 题目内容 分值 时长 对应目标编号 设计意图 I 单句语境填空 15 个单句,考查单元核心词的词性转换与派生(前缀/后缀) 15 5min 1 夯实构词法双基,区分前缀改变意义与后缀改变词性 II 用所给词语填空 10 个单句,从词条表选复合词与缩写词填空 20 5min 1 在语境中运用复合词与缩写,巩固词汇网络 III 构词法类型填空 5 个单句,每句 2 空,考查四种构词法类型与规则 10 5min 2 命名并归纳构词法类型,固化规则 IV 课文语法填空 教材 Using language 原短文(word formation)挖空 15 处 15 15min 2 在教材语篇中内化构词法规律与主旨 V 书面表达填空 英文短文,10 处空白按中文提示补全 20 15min 3 从规则走向表达输出,融合策略意识 VI 构词法辨析改错 10 个易错用法,判断正误+改正+说明规则,覆盖十类构词法陷阱 20 15min 1、3 深度辨析:识别陷阱—纠正误用—归纳规则 五、作业评价 (一)评价维度与量规 维度 A(优秀) B(良好) C(待改进) 权重 得分 知识理解 基础题全对,构词类型与派生精准 少量细节错误 较多基础错误 20% 能力运用 能准确在语篇中运用构词法并推断词义 方法基本正确 方法不当或缺失 30% 思维发展 分析有据,能举例并表达个人见解 表达清楚,欠缺深度 思路混乱,缺乏证据 30% 情感态度 主动运用推测策略,乐于探究构词 态度端正,能完成任务 态度消极,依赖死记 20% 六、试题详情 说明:本部分共六大题,满分 100 分,建议完成时长 60 分钟。其中 V、VI 为原创题(自创材料 / 探究性任务),其余为基础性与提高性训练题。 I.单句语境填空(每小题 1 分,满分 15 分)(基础题) 1.

Words formed by combining other words are called compounds, for example, 5. ________ (a friend that you contact by writing) and 6. ________ (known by many people).

( )_______________ 七、答案与解析 【I.单句语境填空】 【考查目标】考查单元核心词汇在单句中的词性转换与派生(前缀/后缀),落实"语言知识——构词法常识"的基础要求,体现基础性。 【分析】①create→creative(形容词,"富有创造力的");②confuse→confusing(现在分词作形容词,修饰物);③visible→invisible(加前缀 in- 表否定,"看不见的");④create→creativity(加 -ity 名词后缀,"创造力");⑤behave→behaviour / behavior(加 -iour/-or 名词后缀);⑥oppose→opposing(现在分词作形容词,"对立的");⑦harm→harmful(加 -ful 形容词,"有害的");⑧possible→impossible(加 im- 表否定);⑨happy→unhappy(加 un- 表否定);⑩familiar→unfamiliar(加 un- 表否定);⑪likely→unlikely(加 un- 表否定);⑫unique→uniqueness(加 -ness 名词后缀);⑬add→additions(加 -ition 名词复数,"新增词");⑭invent→invention(加 -ion 名词后缀);⑮organize→organization(加 -ation 名词后缀)。解题须先判断句子成分(主语/宾语/定语),再据词性选对派生形式。 【答案】1. creative 2. confusing 3. invisible 4. creativity 5. behaviour / behavior 6. opposing 7. harmful 8. impossible 9. unhappy 10. unfamiliar 11. unlikely 12. uniqueness 13. additions 14. invention 15. organization 【II.用所给词的适当形式填空】 【考查目标】考查单元复合词与缩写词在语境中的准确选用,体现应用性;词条均出自本节教材与单元词表。 【分析】①"笔友"对应 penfriend(pen + friend 复合);②"家庭作业"对应 homework(home + work 复合);③"晕船"对应 seasick(sea + sick 复合);④"想家"对应 homesick(home + sick 复合);⑤"菠萝"对应 pineapple(pine + apple 复合,教材原例);⑥世界卫生组织缩写 WHO;⑦世界贸易组织缩写 WTO;⑧ASAP 是 as soon as possible 的缩写;⑨"知名的"对应 well-known(well + known 复合);⑩美式英语"地铁"对应 subway(单元词表词)。解题须先理解句意,再匹配复合词或缩写。 【答案】1. penfriend 2. homework 3. seasick 4. homesick 5. pineapple 6. WHO 7. WTO 8. ASAP 9. well-known 10. subway 【III.构词法类型填空】 【考查目标】考查对四种主要构词法类型的命名与规则归纳,落实"语法聚焦"的理解要求,体现综合性。 【分析】①"pineapple""penfriend"由两词合成一个词,称为 compound(复合词),combine two words into one new word;②加 un- / in- 通常使词义变为相反(opposite),如 incorrect = not correct;③后缀 -ness 把形容词变为名词(noun),如 unique→uniqueness;④名词用作动词称为 conversion(转化),即 a noun is used as a verb,如 calm(adj.)作 calm sb. down(v.);⑤由首字母组成的词是 abbreviation(缩写),WTO = World Trade Organization。易错点:混淆"前缀改变意义"与"后缀改变词性",以及把 conversion 误认为 compounding。 【答案】1. compounds; one 2. opposite; correct 3. noun; uniqueness 4. conversion; noun 5. abbreviation; World Trade Organization 【IV.课文语法填空】 【考查目标】依托教材 Using language 原短文设空,考查在真实语篇中把握构词法知识、推断词义并内化"英语的趣味性与创造性"的能力,呼应"教考衔接、回归课本"的导向。 【分析】①often 后接动词原形 come;②a lot of 后接形容词 unfamiliar(单元词表词);③are 后接过去分词 formed(被构成);④is 后接过去分词 called;⑤"笔友"填 penfriend;⑥"众所周知的"填 well-known;⑦mean 的宾语填 opposite(反义);⑧isn't correct→incorrect(in- 前缀);⑨isn't happy→unhappy(un- 前缀);⑩are often 后接名词复数 nouns;⑪become 后接形容词 calm;⑫by 后接动名词 presenting;⑬called an 后接单数名词 abbreviation;⑭世界贸易组织填 WTO;⑮is short for 前填 ASAP。解题须回到语篇定位搭配与构词法规律。 【答案】1. come 2. unfamiliar 3. formed 4. called 5. penfriend 6. well-known 7. opposite 8. incorrect 9. unhappy 10. nouns 11. calm 12. presenting 13. abbreviation 14. WTO 15. ASAP (原创)【V.书面表达填空】 【考查目标】考查用构词法术语与衔接表达完成连贯语篇输出的能力,落实语言能力与学习能力,体现应用性与开放性。 【分析】评分看"术语准确 + 衔接自然 + 评论切题 + 结尾升华"。参考答案:①how new words are formed / how words are built;②language full of creativity and fun / a creative and interesting language;③compound formed by combining two or more words;④adding the prefix un-;⑤adding the suffix -ness;⑥use a noun as a verb;⑦What is more / More importantly;⑧unfamiliar words;⑨In a word / In short / All in all;⑩fun and creativity of English / the fun and creativity of English。本题重点在准确使用构词法概念与语篇衔接,而非背诵。本题为半开放性表达,允许同义替换,答案不唯一。 【答案】1. how new words are formed 2. language full of creativity and fun 3. compound formed by combining two or more words 4. adding the prefix un- 5. adding the suffix -ness 6. use a noun as a verb 7. What is more / More importantly 8. unfamiliar words 9. In a word / In short / All in all 10. fun and creativity of English(答案不唯一,合理即可) (原创)【VI.构词法辨析改错】 【考查目标】在语法课语境下,以"辨析—改错—归纳"考察学生对构词法规则的深度理解与运用:覆盖前缀变体(im-/in-/il-/ir-)、后缀拼写(-ion/-ation、y→i)、复合词理据与拼写、转化法、缩写本质、派生与复合之辨、un-/re- 之辨等十类陷阱,落实思维品质与语言能力,体现综合性、应用性与探究性;题目为自创辨析材料,呼应"教—学—评"一致。 【分析】本题为探究性辨析,按"判断—改正—规则"三步评分。①unpossible 错,应为 impossible:possible 以双唇音 p 开头,否定前缀选用 im-(im-/il-/ir-/in- 按后续音选择:p/b/m→im-,l→il-,r→ir-,其余→in-),不用 un-。②happyness 错,应为 happiness:以"辅音字母+y"结尾的形容词加 -ness 前须变 y 为 i。③headball 错,非英语词:复合词须符合语义理据与约定俗成,football 是固定复合词而 headball 不成立。④water 作动词正确:转化法(conversion)允许名词直接作动词,同类有 email、chair、clean。⑤ASAP 错,它是缩写(abbreviation)而非复合词:复合词由完整词组合(football=foot+ball),缩写由首字母组成(ASAP=as soon as possible)。常见失误:只判不改正、把缩写与复合词混淆、前缀变体记错。本题半开放,规则表述可有多种说法,答案不唯一。⑥inventation 错,应为 invention:动词 invent 加名词后缀 -ion(非 -ation);-ation 用于以 -ate 结尾的动词(如 organize→organization)。⑦email 作动词正确:转化法(conversion),同类有 chair、clean。⑧black board 错,应为 blackboard:应写成闭式复合词(一个词)。⑨unhappy 不是复合词而是派生词:复合词须由两个自由词基组合(pineapple=pine+apple),un- 是黏着前缀,unhappy 属“前缀+自由词基”的派生。⑩unlock 中 un- 表“相反/去除”(lock→unlock),re- 才表“再/又”(redo=do again),二者不可混为一谈。 【答案】1. F → impossible(前缀用 im-,不用 un-) 2. F → happiness(y 变 i 再加 -ness) 3. F → 非英语词(复合词须约定俗成,headball 不成立) 4. T(water 由名词转化为动词,转化法 conversion 正确) 5. F → ASAP 是缩写 abbreviation,不是复合词 compound 6. F → invention(动词 invent 加 -ion,不用 -ation;-ation 用于以 -ate 结尾的动词,如 organization) 7. T(email 由名词转化为动词,转化法 conversion 正确,同类有 chair、clean) 8. F → blackboard(应写成一个词 closed compound,不是两个词 black board) 9. F → unhappy 是派生词(前缀 un- + 自由词基 happy),不是复合词;复合词须由两个自由词基组合,如 pineapple = pine + apple 10.

Activity2(巩固式):一篇约130词的说明性短文,要求学生在9个空中填入构词法术语与例 词,从"输入"过渡到"输出",完成"感知一归纳一运用"的闭环。 【Why主题意义(传递意图与价值取向)】 ①写作意图(writer's intention):编者的核心意图是帮助学生完成"零散记忆→系统理解"的认 知跃迁。构词法不是为讲规则而讲规则,而是赋予学生一把拆词的钥匙",让他们从此不必逐词死 记硬背。教材通过Activity 1的"先猜后讲"与Activity2的"在语篇中运用",把"英语的趣味性与创造 性"从感性体验升级为可操作的方法。 ②价值取向与立德树人(values&education).: -学习能力:从"依赖词典"转向"主动推测",培育终身学习的底层能力一这是最具迁移价值的 核心素养: -思维品质:通过比较与分类(如区分"前缀改变意义/后缀改变词性“),锻炼分析与归纳思维: .文化意识:理解英语构词法背后的历史渊源(如大量借用法语、拉丁词根),感受语言作为文 化载体的厚度: -情感态度:当学生发现"原来英语是可以推理的"时,焦虑感显著下降、自信心上升一这是从 "怕英语"到"敢推理"的关键转折。 【How语篇组织特征】 ①体裁(text type):本课时为语法聚焦板块(Grammar Focus),以"例句呈现+规则归纳+语 篇巩固"为编排逻辑;Activity2内的短文是说明性文本(expository),向学生介绍构词法知识。 ②篇章结构(organization):采用"例句感知→规则归纳→语篇运用"的三段式。Activity1是 发现式(学生先匹配例句与类型,教师再揭示规律);Activity2是巩固式(在语篇中运用规则填空)。 这种"先猜后讲"的顺序符合归纳法教学理念,比"先讲后练"更利于深度学习。 ③语言特征(language features): -时态运用:以一般现在时为主(陈述客观规则),辅以少量一般过去时(介绍构词法的历史来 源): -元语言(metalanguage):高频使用构词法术语(compound/prefix/suffix/conversion/ abbreviation),是本课的核心词汇网: -衔接手段:使用"For example'"if."等逻辑连接,结构清晰; -典型例词:unhappy/improvement/uniqueness/pineapple等,既是规则示例,又是学生必须掌 握的高频词,实现"学规则+扩词汇"的双重收益。 教学重难点:重点:四种主要构词法(复合、派生[前缀/后缀]、转化、缩写)的识别与运用, 以及单元核心词的词性转换。难点:在语篇中依据构词法规律推断生词含义,并理解构词法如何体 现英语的趣味性与创造性。 (二)学情分析 维度 具体描述 已有基础 初中接触过un-/dis-等前缀与-er/-ness等后缀;认识pineapple、 homework等复合词;对"拍照photo'"等词性转换有模糊语感 前缀后缀易混(尤其m-与m-的分工);"转化"概念陌生(名词动 现有困惑 用);面对长词不会拆解,仍习惯逐词查询 差异分析 分层设置(基础提高/拓展);基础档保底派生与复合,提高档回到教材 语篇内化,拓展档完成开放性微写作,由浅入深 (三)设计意图 本课时作业以"感知一理解一辨析"为线索,按标准题型分层命制:先以单句与语篇填空夯实构 词双基(派生、复合、缩写),再以教材原短文填空回到本课时语篇内化规律,最后以"构词法辨 析改错"考察规则的深度运用与迁移。答案解析逐块给出"考查目标一分析一答案”,便于自查与批 改,落实"教一学一评"一致。 三、作业目标 目标维度 编号 具体目标 对应核心素养 评价证据 能识别并运用英语四种主要构词 法(复合、派生[前缀/后缀]、转 单句与语篇填空中构词正 知识理解 化、缩写),将单元核心词按构 语言能力 确率≥80% 词法规律进行词性转换与派生 能在教材语篇中依据构词法知识 能力运用 猜测、推断生词含义,并举例说 语言能力、思 课文语篇填空准确,并能 2 举例说明至少1个构词现 明构词如何体现英语的趣味性与 维品质 象 创造性 能体会构词法背后的规律与理 微写作中能运用构词法规 思维发展、 据,认识到英语是可以推理的活 思维品质学习 律解释或自创1个英语表 情感态度 的语言,增强主动推测而非死记 能力 硬背的策略意识 达,并表达个人见解 四、作业内容与目标对应表 题 号 题型 题目内容 分值 对应目标 时长 编号 设计意图 单句语境填空 15个单句,考查单元核心词 夯实构词法双基, 15 5min 1 的词性转换与派生(前缀/后 区分前缀改变意义 缀) 与后缀改变词性 在语境中运用复合 用所给词语填 10个单句,从词条表选复合 I 20 词与缩写,巩固词 空 词与缩写词填空 5min 汇网络 构词法类型填 5个单句,每句2空,考查四 命名并归纳构词法 Ⅱ 10 空 种构词法类型与规则 5min 类型,固化规则 教材Using language原短文 在教材语篇中内化 V 课文语法填空 15 15min (word formation)挖空15处 构词法规律与主旨 英文短文,10处空白按中文 从规则走向表达输 书面表达填空 提示补全 20 15min 出,融合策略意识 10个易错用法,判断正误+改 深度辨析:识别陷 VI 构词法辨析改 错 正+说明规则,覆盖十类构词 20 15min 1、3 阱一纠正误用一归 法陷阱 纳规则 五、作业评价 (一)评价维度与量规 维度 A(优秀) 权 得 B(良好) C(待改进) 重 分 基础题全对,构词类型与 知识理解 少量细节错误 较多基础错误 20 派生精准 能准确在语篇中运用构词 能力运用 方法基本正确 方法不当或缺失 30 法并推断词义 % 分析有据,能举例并表达 思路混乱,缺乏证 思维发展 表达清楚,欠缺深度 30 个人见解 据 % 主动运用推测策略,乐于 情感态度 态度端正,能完成任务 态度消极,依赖死 20 探究构词 记 % 六、试题详情 说明:本部分共六大题,满分100分,建议完成时长60分钟。其中V、VI为原创题(自创材 料/探究性任务),其余为基础性与提高性训练题。 I.单句语境填空(每小题1分,满分15分)(基础题) 1.English is a highly (create)language full of surprises. 2.The (confuse)instructions were so unclear that nobody knew what to do. 3.Stars are visible at night,but they are(visible)in the daytime. 4.When we study word formation,we see the (create)of the human race. 5.His strange (behave)at the party surprised everyone present. 6.People hold (oppose)views on how best to learn new words. 7.Eating too much sugar is(harm)to your teeth. 8.It is (possible)to learn every word,but rules can help us guess. 9.If someone is not happy with the result,they are (happy). 10.Many new words are not(familiar)to first-year students. 11.Heis (likely)to forget his promise and be late again. 12.The (unique)of English lies in its word formation. 13.Each year many (add)are made to English dictionaries. 14.Her (invent)of this method saved the class much time. 15.Good (organize)of your notes helps you review more efficiently.

( 4.We can say"We water the flowers",turning the noun"water"into a verb.

①likely-→unlikely(加un-表否定);②nique-→uniqueness(加-ness名词后缀);③add一→additions (加-ition名词复数,"新增词");①④invent-→invention(加-ion名词后缀);⑤organize-→organization (加-aton名词后缀)。解题须先判断句子成分(主语/宾语/定语),再据词性选对派生形式。 1.creative 2.confusing 3.invisible 4.creativity 5.behaviour/behavior 6.opposing 7. harmful 8.impossible 9.unhappy 10.unfamiliar 11.unlikely 12.uniqueness 13.additions 14. invention 15.organization 【IⅡ用所给词的适当形式填空】 【考查目标】考查单元复合词与缩写词在语境中的准确选用,体现应用性:词条均出自本节教材与 单元词表。 【分析】①"笔友"对应penfriend(pen+friend复合);②"家庭作业"对应homework(home+work 复合);③"晕船"对应seasick(sea+sick复合);④"想家"对应homesick(home+sick复合);⑤" 菠萝"对应pineapple(pine+apple复合,教材原例);⑥世界卫生组织缩写WHO:⑦世界贸易组织 缩写WTO;⑧ASAP是as soon as possible的缩写;⑨"知名的"对应well-known(well+known复合); ⑩美式英语"地铁"对应subway(单元词表词)。解题须先理解句意,再匹配复合词或缩写。 【答案】1.penfriend2.homework3.seasick4.homesick5.pineapple6.WHO7.WTO8.ASAP 9.well-known 10.subway 【III构词法类型填空】 【考查目标】考查对四种主要构词法类型的命名与规则归纳,落实"语法聚焦”的理解要求,体现综 合性。 【分析】①"pineapple'"'penfriend"由两词合成一个词,称为compound(复合词),combine two words into one new word;②加un-/im-通常使词义变为相反(opposite),如incorrect=not correct;③后 缀-ness把形容词变为名词(noun),如unique-→uniqueness;④名词用作动词称为conversion(转 化),即a noun is used as a verb,如calm(adj.)作calm sb.dowm(v.);⑤由首字母组成的词是 abbreviation(缩写),WTO=World Trade Organization。易错点:混淆"前缀改变意义"与"后缀改变 词性",以及把conversion误认为compounding。 [1.compounds;one 2.opposite;correct 3.noun;uniqueness 4.conversion;noun 5.abbreviation; World Trade Organization 【IV课文语法填空】 【考查目标】依托教材Using language原短文设空,考查在真实语篇中把握构词法知识、推断词义 并内化"英语的趣味性与创造性"的能力,呼应"教考衔接、回归课本"的导向。 【分析】①often后接动词原形come:②a lot of后接形容词unfamiliar(单元词表词):③ae后接过 去分词formed(被构成);④is后接过去分词called;⑤"笔友"填penfriend;⑥"众所周知的"填wel- kowm;⑦mean的宾语填opposite(反义):⑧isn't correct-→incorrect(in-前缀);⑨isn't happy→unhappy (un-前缀);⑩are often后接名词复数nouns;①become后接形容词calm;2by后接动名词 presenting;③called an后接单数名词abbreviation;④世界贸易组织填WTO:⑤is short for前填ASAP。 解题须回到语篇定位搭配与构词法规律。 1.come 2.unfamiliar 3.formed 4.called 5.penfriend 6.well-known 7.opposite 8.incorrect 9.unhappy 10.nouns 11.calm 12.presenting 13.abbreviation 14.WTO 15.ASAP (原创)【V.书面表达填空】 【考查目标】考查用构词法术语与衔接表达完成连贯语篇输出的能力,落实语言能力与学习能力, 体现应用性与开放性。 【分析】评分看"术语准确+衔接自然+评论切题+结尾升华"。参考答案:①how new words are formed/how words are built:2language full of creativity and fun /a creative and interesting language; 3compound formed by combining two or more words:4adding the prefix un-:5adding the suffix-ness; ⑥use a noun as a verb;⑦What is more/More importantly;⑧unfamiliar words;⑨In a word/In short /All in all;⑩fun and creativity of English/the fun and creativity of English。本题重点在准确使用构词 法概念与语篇衔接,而非背诵。本题为半开放性表达,允许同义替换,答案不唯一。 【答案】1.how new words are formed2.language full of creativity and fun3.compound formed by combining two or more words 4.adding the prefix un-5.adding the suffix -ness 6.use a noun as a verb 7.What is more /More importantly 8.unfamiliar words 9.In a word /In short /All in all 10.fun and creativity of English(答案不唯一,合理即可) (原创)【VI构词法辨析改错】 【考查目标】在语法课语境下,以"辨析一改错一归纳考察学生对构词法规则的深度理解与运用: 覆盖前缀变体(im-in-/il-/imr-)、后缀拼写(-ion/-ation、y→i)、复合词理据与拼写、转化法、缩写 本质、派生与复合之辨、n-1e-之辨等十类陷阱,落实思维品质与语言能力,体现综合性、应用性 与探究性;题目为自创辨析材料,呼应"教一学一评"一致。 【分析】本题为探究性辨析,按"判断一改正一规则"三步评分。①unpossible错,应为impossible: possible以双唇音p开头,否定前缀选用im-(im-/il-ir-in-按后续音选择:p/b/m→in-,1→il-,r→ir-, 其余→in-),不用un-。②happyness错,应为happiness:以"辅音字母+y"结尾的形容词加-ness前 须变y为i。③headball错,非英语词:复合词须符合语义理据与约定俗成,football是固定复合词而 headball不成立。④water作动词正确:转化法(conversion)允许名词直接作动词,同类有email、 chair、clean。⑤ASAP错,它是缩写(abbreviation)而非复合词:复合词由完整词组合 (football-foot+-ball),缩写由首字母组成(ASAP=as soon as possible)。常见失误:只判不改正、 把缩写与复合词混淆、前缀变体记错。本题半开放,规则表述可有多种说法,答案不唯一。 ⑥inventation错,应为invention:动词invent加名词后缀-ion(非-ation);-ation用于以-ate结尾 的动词(如organize→organization)。⑦email作动词正确:转化法(conver'sion),同类有chair、 clean。⑧black board错,应为blackboard:应写成闭式复合词(一个词)。⑨unhappy不是复合词而 是派生词:复合词须由两个自由词基组合(pineapple-pine+apple),un-是黏着前缀,unhappy属“前 缀+自由词基”的派生。⑩nlock中un-表“相反/去除”(lock→unlock),re-才表“再/又”(redo=do again),二者不可混为一谈。 【答案】1.F→impossible(前缀用im-,不用un-) 2.F一happiness(y变i再加-ness) 3.F→非英语词(复合词须约定俗成,headball不成立) 4.T(water由名词转化为动词,转化法conver'sion正确) 5.F→ASAP是缩写abbreviation,不是复合词compound 6.F→invention(动词invent加-ion,不用-ation;-ation用于以-ate结尾的动词,如organization) 7.T(email由名词转化为动词,转化法conversion正确,同类有chair、clean) 8.F→blackboard(应写成一个词closed compound,不是两个词black board) 9.F→unhappy是派生词(前缀um-+自由词基happy),不是复合词;复合词须由两个自由词基组 合,如pineapple=pine+apple 10.F→un-表“相反/去除”(unlock=锁上→解开),re-才表“再/又”(redo=do again) 【评分建议】每小题2分(判断0.5分+改正1分+规则0.5分)=20分:只判断不改正或规则表 述不清酌情扣分;能使用本课时术语(prefix/suffix/compound/conversion/abbreviation)作答者给 满分。
