译林版《英语》八年级上册
Unit 2 School life Grammar教学设计
一、教材分析
本单元的话题是“学校生活”,属于“人与自我”主题范畴下的“生活与学习”主题群中的“多彩、安全、有意义的学校生活”子主题。涉及的语篇类型有图片、音频、对话、博客文章、表格、说明文、日记和建议书等。本单元的教学旨在帮助学生了解中外不同类型的学校和丰富的校园生活,感知文化差异,鼓励学生在感受多姿多彩的校园生活的同时,基于生活实际积极思考,提出改善校园生活的合理建议,培养学生的思辨能力及热爱校园生活、积极向上的态度,促使学生认识到教育的重要性,并努力提升自身素养。本单元的主题句为“Education is our passport to the future.”,旨在引导学生理解教育的重要性,激发学生主动学习的热情,促使其在美好的校园生活中学习知识技能,提升思维品质,塑造优秀的品格并提升个人修养。
本课是Unit 2 Grammar板块,话题围绕校园生活展开,计划1课时。本板块分为两部分。第一部分(A Comparing the amount of things)首先呈现Kitty从网上收集的三所学校(Nancy的Woodland Secondary School、Tomoya的Gekko Middle School、Linlin的学校)在班级规模、午餐时长和暑假时长三个维度上的对比表格及例句,引导学生关注fewer/the fewest、less/the least和more/the most的形式特征和表达的意义,归纳其在比较事物数量时的使用规则;接着设置Part A1,以表格形式展示Nancy、Tomoya、Kitty三人校园生活的基本信息,涵盖学科数量、社团数量和每日空闲时长三个维度,要求学生观察表格并完成语篇填空;最后设置Part A2,鼓励学生先根据自身实际情况补全表格最后一列,再写一篇短文,比较自己与Nancy、Tomoya、Kitty的学校生活。第二部分(B Using as ... as)首先呈现比较Nancy和Tomoya校园生活的四个例句,引导学生关注as ... as与not as ... as的形式特征和表达的意义,归纳其使用规则;接着设置Part B1,要求学生运用(not) as ... as完成Kitty比较自己学校与Laura学校的语篇填空;最后设置Part B2,鼓励学生运用所学语法写一篇短文,比较自己的初中生活与小学生活。教材第148页的Grammar check对本板块的语法规则进行了系统梳理,可在归纳总结环节加以运用。
二、学情分析
从语言知识与技能层面来看,学生在七年级已学习过形容词和副词比较级、最高级的构成与基本用法,能够运用“-er/-est”“more/the most”对人或事物的特征进行比较,这为学习本板块用fewer/the fewest、less/the least、more/the most比较事物的数量奠定了基础。但学生极易混淆两套体系:一是分不清比较“数量”与比较“特征”的差别,二是在比较数量时难以判断该用fewer还是less,常出现“less books”“fewer homework”这类错误,根源在于对可数名词与不可数名词的辨识能力不足。同时,学生对as ... as这一同级比较结构接触较少,容易出现两大典型错误:一是在as ... as中间误用比较级(如as bigger as);二是被比较双方不同类(如Her book is as thick as me.)。这些易错点均在教材第148页Grammar check中有明确提示,教学中应充分利用。
从认知与情感层面来看,八年级学生具备初步的观察、比较与归纳能力,能够在教师引导下从例句中发现语言形式与意义的联系,自主归纳语法规则。本板块所有语法现象都镶嵌在“比较不同学校的校园生活”这一真实情境中,表格数据直观,贴近学生生活,能够有效降低语法学习的抽象感和枯燥感。但语法规则的归纳需要从具体例句中抽象出来,对部分学生而言仍有一定难度,需要教师设计由浅入深的活动链,从“两两比较”到“三者比较”,从“单句操练”到“语篇运用”,循序渐进。同时,学生在完成A2和B2两项开放性写作任务时,需要调用自身真实信息,容易出现无话可说或表达单一的情况,需要教师提供充分的语言支架和示范。
三、教学目标
通过本课的学习,学生能够:
1. 在语境中获取和梳理fewer/the fewest、less/the least和more/the most的形式特征、比较事物数量时的意义和使用规则,完成“Work out the rule!”;
2. 运用上述规则完成教材A1语篇填空,并根据表格信息造句,巩固和内化其用法;
3. 获取和梳理as ... as与not as ... as在比较人或事物特点时的意义和使用规则,完成教材B1语篇填空;
4. 在谈论自己校园生活的情境中,正确运用所学结构完成教材A2与B2的写作任务,比较事物数量与校园生活的特点,分享积极向上的校园生活。

1. 在语境中获取和梳理fewer/the fewest、less/the least和more/the most的形式特征、比较事物数量时的意义和使用规则,完成“Work out the rule!”。
Step 1:Presentation — comparing the amount of two things
学生观察第26页第一张表格,描述三所学校的基本信息。
Nancy Tomoya Linlin
Class size 20 students 35 students 30 students
Lunchtime 60 minutes 70 minutes 90 minutes
Summer holiday 7 weeks 6 weeks 8 weeks
Possible answer
There are 20 students in each class at Nancy’s school.
At Tomoya’s school, students have a 70-minute lunch break.
Linlin’s school has 8 weeks off for the summer holiday.
学生两两比较,运用比较级描述两所学校的差异。
Possible answer
There are fewer students in each class at Nancy’s school than at Tomoya’s school.
Nancy’s school has less lunchtime than Tomoya’s school.
Nancy’s school has more weeks off for the summer holiday than Tomoya’s school.
学生归纳比较两者数量的规则。
Work out the rule!
fewer + countable nouns + than
less + uncountable nouns + than
more + countable/uncountable nouns + than
Step 2:Presentation — comparing the amount of three or more things
学生三者比较,运用最高级描述三所学校的差异。
Possible answer
Tomoya’s school has the most students in each class.
Nancy’s school has the least lunchtime among the three schools.
Tomoya’s school has the fewest weeks off for the summer holiday.
学生归纳比较三者或三者以上数量的规则。
Work out the rule!
the fewest + countable nouns
the least + uncountable nouns
the most + countable/uncountable nouns
学生完成第26页“Work out the rule!”填空。
Answer: fewer; the fewest; less; the least; more; the most
根据学生对表格信息的描述,评估学生能否准确读取并转述数据;根据学生两两比较与三者比较造句的准确率,评估学生能否区分比较级与最高级的使用场景;根据学生归纳的规则是否完整、准确,评估学生的观察能力与归纳能力;根据学生“Work out the rule!”的填空结果,评估学生对形式特征的掌握程度。
设计意图:语法学习从真实数据出发,避免孤立地讲解规则。先“两两比较”再“三者比较”,符合学生由易到难的认知规律;表格中students、weeks为可数名词,lunchtime为不可数名词,学生在反复比较中自然感知fewer与less的分工,把抽象的可数/不可数概念转化为可以观察的语言事实,实现从“教师讲规则”到“学生发现规则”的转变。
2. 运用上述规则完成教材A1语篇填空,并根据表格信息造句,巩固和内化其用法。
Step 3:Practice — Part A1
学生观察第26页A1表格,运用所学知识完成Kitty的短文。
Nancy Tomoya Kitty Me
Subjects 11 14 13
Clubs 3 2 4
Free time each day 4 hours 3 hours 2 hours
Answer
(1) more (2) more (3) most (4) more (5) fewer
(6) fewest (7) less (8) more (9) least (10) most
学生根据A1表格信息,完成句子,进一步巩固规则。
(1) Nancy studies ______________ subjects than Tomoya.
(2) Kitty is in the ______________ clubs among the three students.
(3) Kitty has ______________ free time each day than Nancy.
(4) Kitty is in ______________ clubs than Tomoya.
(5) Nancy studies the ______________ subjects among the three students.
(6) Among the three students, Kitty has the ______________ free time each day.
Answer: (1) fewer (2) most (3) less (4) more (5) fewest (6) least
TIP
教师引导学生归纳易错点,形成记忆口诀,并对照第148页Grammar check加以验证。
“多”一律用 more / the most;
“少”要分家 —— 可数用 fewer / the fewest,不可数用 less / the least。
改错练习
I have less books than Tomoya. ☹ → I have fewer books than Tomoya. ☺
Kitty has fewer free time than Nancy. ☹ → Kitty has less free time than Nancy. ☺
根据学生A1填空的准确率,评估学生在语篇层面运用比较数量结构的能力;根据学生六个句子填空的结果,评估学生能否根据名词的可数性正确选择fewer/less与fewest/least;根据学生改错练习的表现,评估学生能否识别并纠正常见的搭配错误。
设计意图:A1把离散的规则嵌入连续的语篇,学生必须在上下文中判断比较的对象、数量与范围,这是从“会背规则”走向“会用规则”的关键一步;六个补充句子全部围绕同一张表格设计,形成高密度、低认知负荷的强化训练;口诀与改错直击中国学生最典型的错误,并引导学生回扣教材Grammar check自主验证,培养借助工具书学习的习惯。
3. 获取和梳理as ... as与not as ... as在比较人或事物特点时的意义和使用规则,完成教材B1语篇填空。
Step 4:Presentation — using as … as
学生阅读第27页Kitty的笔记,观察并回答问题。
The arts are as important as languages, Maths and Science at Nancy’s school.
Nancy’s school life is as wonderful as Tomoya’s.
Nancy’s school is not as big as Tomoya’s.
Tomoya’s summer holiday is not as long as Nancy’s.
Q1: What does Nancy’s school think of the arts?
Q2: Is Nancy’s school life less wonderful than Tomoya’s?
Q3: Is Nancy’s school the same size as Tomoya’s school?
Q4: Do Nancy and Tomoya have the same weeks off for the summer holiday?
Q5: What does “as … as” mean in the sentences?
Possible answer
(1) Nancy’s school thinks the arts are as important as languages, Maths and Science.
(2) No. Nancy’s school life is as wonderful as Tomoya’s.
(3) No. Nancy’s school is smaller than/not as big as Tomoya’s school.
(4) No, they don’t. Nancy has more weeks off.
(5) It means that people or things are the same in some way.
学生归纳as ... as的用法,并完成第27页“Work out the rule!”。
Answer: as … as; not as … as
TIP: not as ... as = not so ... as
Step 5:Practice — Part B1
学生根据括号中所给词,运用(not) as ... as完成句子。
(1) Nancy thinks Chinese is ______________ (simple) French.
(2) Safety programmes are ______________ (important) other subjects at Tomoya’s school.
(3) The subjects at Tomoya’s school are ______________ (interesting) those at Nancy’s school.
(4) Nancy’s lunchtime is ______________ (long) Tomoya’s.
Answer: (1) not as simple as (2) as important as (3) as interesting as (4) not as long as
学生完成第27页B1语篇填空。
Answer: (1) not as old as (2) as good as (3) as hard-working as (4) not as big as (5) as beautiful as
TIP
教师引导学生关注同级比较的两大易错点。
① as ... as 中间必须用形容词或副词原级。
My school is as bigger as Laura’s. ☹ → My school is as big as Laura’s. ☺
② 被比较的双方必须是同类事物。
Her book is as thick as me. ☹ → Her book is as thick as mine. ☺
根据学生对五个问题的回答,评估学生能否准确理解as ... as与not as ... as的意义差别;根据学生归纳的规则是否准确,评估学生对形式特征的把握;根据学生四个单句与B1语篇填空的完成情况,评估学生能否根据语境判断用原级还是否定式、能否正确使用原级;根据学生改错练习的表现,评估学生能否规避两类典型错误。
设计意图:从Reading板块学过的原句切入,使学生对as ... as的感知有据可依,新知与旧知自然衔接;五个问题由意义理解到形式归纳,层层递进;B1的语篇填空把比较对象从“学校”扩展到“我与朋友”,贴近学生真实生活;最后集中呈现“原级”与“同类”两大易错点,并采用对错对照的直观方式,帮助学生在正误辨析中形成清晰的语言意识。
4. 在谈论自己校园生活的情境中,正确运用所学结构完成教材A2与B2的写作任务,比较事物数量与校园生活的特点,分享积极向上的校园生活。
Step 6:Production — Part A2
学生在A1表格的最后一列填写自己的信息,并与同伴交流。
学生写一篇短文,比较自己的学校生活与Nancy、Tomoya、Kitty的学校生活。
Possible answer
I study 12 subjects at school. I study more subjects than Nancy, but fewer than Tomoya and Kitty. I am in only 1 club, so I am in the fewest clubs. I have 3 hours of free time every day. I have more free time than Kitty, but less than Nancy.
Step 7:Production — Part B2
学生借助表格,比较自己的初中与小学,写一篇短文。
My middle school My primary school
Size
History
Teachers
Students
Facilities
My opinion
Possible answer
My primary school is not as large as my middle school. There are over 1,000 students at my middle school, but my primary school has only about 500 students. My primary school is not as old as my middle school. My middle school has a history of over 100 years. It is a famous school. The teachers here are as kind as those at my primary school. They are always willing to help students. My middle school classmates are as hard-working as my primary school classmates. We learn a lot together every day. The library at my primary school is not as big as the one at my middle school. The library at my middle school has more books than the one at my primary school. I think both schools are wonderful.
Sharing
学生交换短文,同桌互评:信息是否真实、结构是否准确、比较是否有意义。
评价要点:数量比较是否用了fewer/less/more与the fewest/least/most?同级比较是否用了原级?被比较的双方是否同类?
教师引导总结。
比较不是为了分出高下,而是为了看见不同、学会欣赏。
Education is our passport to the future.
根据学生A2短文中数量比较结构的准确性,评估学生能否在真实语境中正确比较事物数量;根据学生B2短文中as ... as与not as ... as的使用情况,评估学生能否正确比较事物的特点;根据学生写作内容的丰富度与真实性,评估学生能否调用自身经验进行有意义的表达;根据互评的准确性,评估学生对本板块规则的掌握程度。
设计意图:A2与B2是两项真实的写作任务,要求学生调用自身数据、表达个人体验,实现语法知识向语用能力的转化;表格支架帮助学生理清比较的维度,避免写作时无从下笔;同伴互评把评价量表转化为具体的检查要点,使评价过程本身成为又一次语言学习;教师的总结语把语法学习上升到价值层面,引导学生以开放、包容的心态看待差异,与单元主题形成呼应。
Homework
For All: Finish your writing in Part B2 and check it with the Grammar check on page 148.
For some: Interview one of your teachers about his or her middle school life and write five sentences comparing it with yours, using fewer/the fewest, less/the least, more/the most and (not) as ... as.
Unit 2 School life
Grammar: Comparing the amount of things & using as ... as
比较两者数量 比较三者及以上数量
fewer + 可数 + than the fewest + 可数
less + 不可数 + than the least + 不可数
more + 可数/不可数 + than the most + 可数/不可数
同级比较
as + 原级 + as 和……一样
not as/so + 原级 + as 不如……
TIP: 中间用原级!双方要同类!
