复习导入
Warm-up
Free talk:Look at the two pictures. What differences can you find between the two schools? (e.g., class size, lunchtime, holidays) 看两校图片找不同。
追问:Do you think your school has more or fewer subjects than the school in the picture? Why? Is your summer holiday as long as theirs?——比较级与 as...as 提前露面,引出本课两大结构。
从班级人数、午餐时间、假期等维度找两校不同;
用 more/fewer 与 as long as 初步表达比较。
数据表铺垫
Data table
数据表:Nancy|Tomoya|Linlin——Class size 20/35/30 students;Lunchtime 60/70/90 minutes;Summer holiday 7/6/8 weeks。
引导发现:三个维度覆盖两类名词——学生(可数复数)、午餐时间(不可数)、假期周数(weeks 可数)——同一张表可数与不可数的比较各有各的词。
读表提取三人三维度数据;
区分三个维度对应的名词类型。
规则推导
Rule discovery
四组推导:①few–fewer–fewest(可数)——Tomoya's school has a few students.→My school has fewer students.→Nancy's school has the fewest students. ②little–less–least(不可数)——Linlin's lunchtime lasts 90 minutes.→Tomoya's school has less lunchtime.→My school has the least lunchtime. ③much–more–most(不可数)——Nancy's school has much lunchtime.→more→the most lunchtime. ④many–more–most(可数)——many weeks off→more weeks off→the most weeks off.
点破词源逻辑:few 配可数、little 配不可数各走各的变形;many 与 much 是同源双胞胎,比较级合流为 more/most——所以 more/most 天生通用。
朗读四组推导句并观察变形;
从词源理解 more/most 通用的原因;
归纳「先看名词类型再选比较词」。
归纳铁律
Rules summary
We compare the amount of things like this:fewer and the fewest with countable nouns;less and the least with uncountable nouns;more and the most with both countable and uncountable nouns.
记忆口诀:可数名词比多少——fewer/the fewest;不可数名词比多少——less/the least;两者通用比多少——more/the most。点破 fewer 与 less 的区分是本课最核心易错点,考试常通过名词单复数设置陷阱;三秒判断法:能加 a/an/数词或词尾有 s→可数→fewer;时间/金钱/液体/抽象概念→不可数→less。
齐读三行铁律与记忆口诀;
练习三秒判断法:students/clubs/time/free time/water 各归哪行。
十空实战
Controlled practice
数据表:Subjects 11/14/13;Clubs 3/2/4;Free time 4h/3h/2h(Nancy/Tomoya/Kitty)。Kitty 十空:(1) more subjects than Nancy (2) more subjects than I do (3) the most among the three of us (4) more clubs than Tomoya (5) fewer clubs than I am (6) the fewest clubs (7) less free time than Tomoya (8) more free time (9) the least free time (10) the most free time.
点破三步走:先看表格数字比大小→再判名词可数(subjects/clubs 可数,free time 不可数)→最后按行选词——第 4-6 空 clubs 走 fewer 线,第 7-10 空 free time 走 less 线,同一篇短文两线交替。
按三步走独立完成十空;
核对答案并说出每空依据(数字比较+名词类型);
体会同一语篇两条线的交替使用。
同级比较
as...as
四句观察:1 The arts are as important as languages, Maths and Science at Nancy's school. 2 Nancy's school life is as wonderful as Tomoya's.(肯定:as+原级+as 表相同)3 Nancy's school is not as big as Tomoya's. 4 Tomoya's summer holiday is not as long as Nancy's.(否定:not as...as 表不同)Tip: not as...as = not so...as。
归纳:We use as...as to say that people or things are the same in some way; we use not as...as to say they are not the same in some way.——中间全部原级,是与比较级的分水岭。
朗读四句并分出肯定/否定两派;
归纳 as...as 与 not as...as 的语义;
确认中间必须用原级。
五空运用
Contextual practice
Kitty 对比 Laura 学校五空:(1) not as old as(我校只有十年历史,Laura 校超百年)(2) as good as each other(两校一样好,学生都学到很多)(3) as hard-working as those at mine(her school 的师生和我校的一样勤奋——those 代替 teachers)(4) not as big as the one at Laura's school(图书馆不如她校大——the one 代替 library)(5) as beautiful as the garden at Laura's school(花园一样漂亮)。
点破:数字线索定方向(10 年 vs 100 年→不如旧);those/the one 代替比较对象时单复数对齐;Laura's=Laura's school 所有格避免「学校与人」的逻辑错误。
独立完成五空并核对;
分析 those/the one 的替代对象与单复数;
理解 Laura's 所有格的含义。
口头输出
Oral output
Compare your middle school with your primary school. 用所学语法写短文对比中学与小学,表格六行:Size/History/Students/Teachers/Facilities/My opinion。
示例骨架:My middle school is bigger than my primary school. It has more students and fewer teachers... The playground is not as large as..., but the library is as modern as... In my opinion, both schools are wonderful in their own ways.
填表格列对比维度;
成段输出,至少三处数量比较词+两处同级比较;
同伴互查语法结构是否达标。
语言点精讲
Language points
①fewer 与 less:都表示「更少的」但修饰对象严格区分——fewer 只修饰可数名词复数(There are fewer cars on the road today.);less 只修饰不可数名词(Please add less sugar to my coffee. 请给我的咖啡少加点糖)。本节最核心易错点,考试常通过名词单复数设陷阱。
②the fewest 与 the least:最高级前必须加 the——the fewest 修饰可数(Our class has the fewest students in our grade./She made the fewest mistakes in the test.);the least 修饰不可数(This bottle has the least water of all.)
③more 与 the most:可数不可数通用,无需区分——解题时的「安全选项」(Nancy has more subjects than Daniel./Our school has the most clubs in the city./I need more time to finish this task.)
④as...as 肯定句:中间必须接形容词/副词原级,绝不能用比较级或最高级;第二个 as 后接比较对象,所属关系用名词所有格(Laura's=Laura's school)——This book is as interesting as that one./He runs as fast as his brother.(副词原级同样适用)
⑤not as...as 否定句:与 not so...as 可互换,中间只能用原级,否定句中不能省略第一个 as/so——Nancy's summer holiday is not as long as John's./This film is not as wonderful as the last one./My bag is not so heavy as yours. 我的书包没有你的重。
五组语言点逐组理解并造句;
熟记三句钉子:fewer 可数、less 不可数、more/most 通用;the fewest/the least 别丢 the;as...as 中间原级;
用检测题反向验证三步走:先读语境、再判名词、后选词。
随堂检测
Testing
完成随堂检测:教师发放随堂检测题,学生限时独立完成后,教师逐题核对讲评。
【一、单项选择】
1. — Which bag is heavier, the red one or the blue one? — The red one is __________ the blue one. They weigh the same. A. not as heavy as B. as heavy as C. heavier than D. the heaviest
2. Daniel has __________ homework than Simon, but Simon has __________ subjects than Daniel. A. less; fewer B. fewer; less C. less; less D. fewer; fewer
【二、用括号内单词的正确形式填空】
3. My brother has __________ (few) toys than me, but he has __________ (little) free time.
4. Among all the students, Lily spends __________ (little) time on computer games.
5. There are __________ (many) clubs in our school than in Tom's school.
6. This dictionary is not as __________ (useful) as that one.
7. Of the three girls, she made __________ (few) mistakes in the exam.
限时独立完成随堂检测,不看笔记、不讨论;
完成后与同桌交换互批,逐题核对答案并订正;
订正后用红笔标注错题涉及的规则(toys 可数 fewer/free time 不可数 less/the least 最高级加 the/as...as 原级 useful/the fewest),纳入复习清单。
参考答案:一、1. B 2. A 二、3. fewer;less 4. the least 5. more 6. useful 7. the fewest
归纳与作业
Summary & Homework
Summary:数量比较——修饰可数名词复数用 fewer/the fewest;修饰不可数名词用 less/the least;两者通用 more/the most。同级比较——肯定句 as+adj./adv.原级+as;否定句 not as/so+adj./adv.原级+as。核心口诀——可数 fewer,不可数 less;more/most 两者通;同级比较用原级。
Homework:Review——Memorize the grammar rules and complete the exercise on page 28. 背记语法规则并完成 28 页练习。Preview——Preview the next lesson. 预习下一课。
默写核心口诀自查;
记录两项作业:背规则完成 28 页练习;预习下一课。
作业设计(分层)
【基础·必做】抄写并记忆核心口诀(可数 fewer,不可数 less;more/most 两者通;同级比较用原级)与 the fewest/the least 的 the,完成课本 28 页练习。
【提升·选做】用 fewer/less/the fewest/the least/more/the most 各造一句比较 Nancy、Tomoya 和 Kitty 三人的学校生活(可自设数据)。
【拓展·挑战】以 My Middle School vs My Primary School 为题写 80 词左右对比短文:至少三处数量比较词、两处 as...as/not as...as,结尾用 In my opinion, both schools are wonderful in their own ways. 收束。
板书设计
Unit 2 School life — Grammar 数量比较与同级比较
数量:fewer/the fewest+可数复数|less/the least+不可数|more/the most 通用
同级:as+原级+as(一样)|not as/so+原级+as(不如)
口诀:可数 fewer,不可数 less;more/most 两者通;同级比较用原级
陷阱:the fewest/the least 别丢 the|as...as 中间无比较级
教学评价与反思
1. 目标—评价对应(教-学-评一体化):
素养目标
课堂评价任务与证据
语言能力:数量比较与同级比较结构
四组推导句;Kitty 十空;Laura 五空;随堂检测八空
文化意识:中外校园比较中的教育差异
三人三维度数据对比;中小学对比的口头输出
学习能力:图表归纳与三步解题法
数据表→规则→口诀的自主归纳;「比大小→判名词→选词」三步走
思维品质:可数不可数的分类思维
fewer/less 陷阱辨析;those/the one 替代对象的单复数对齐;检测语境推理
2. 预设反思点:
以两校找不同复习导入,as long as 的追问让同级比较提前露面;三人三维度数据表是全课引擎,Class size/Lunchtime/Summer holiday 恰好覆盖可数与不可数两类名词;四组推导从原级到比较级到最高级一路生成,many 与 much 同源合流为 more/most 的词源逻辑让「通用」不用死记;三行铁律配「三秒判断法」(能加 a/an/数词→可数),fewer/less 陷阱当场拆解;Kitty 十空用「比大小→判名词→选词」三步走,clubs 与 free time 两线交替是活教材;as...as 四句分肯定否定两派,not as...as=not so...as 可互换;Laura 五空的数字线索(10 年 vs 100 年)与替代词 those/the one 的单复数对齐是精度训练;口头输出中小学对比让语法回归表达,自查双保险(数量词三处+同级两处)落在笔下;语言点五组钉成三句话,the fewest/the least 别丢 the 与 as...as 中间无比较级是检测雷区;随堂检测两选六填当堂闭环,口诀抄错题本首页的作业设计让规则随复习常新。
