Unit 3 Same or Different? Section A (Grammar Focus 3a-3c) 教学设计(第三课时·语法课) 2026—2027学年 人教版(2024)英语八年级上册 课  题 Same or Different?(Unit 3 Section A Grammar Focus 3a-3c) 课  型 语法课(Grammar) 课  时 第3课时(45分钟) 授课年级 八年级上册 核心素养目标 素养维度 目标描述 语言能力 识别并理解比较级的意义;系统归纳形容词、副词比较级的构成规则(加-er / 加-r / 双写辅音字母 / 变 y 为 i / 前加 more)与不规则变化(good/well—better 等);掌握“比较级+than”句型、比较级前用 much, a little, a lot, even 修饰及“as+原级+as / not as/so+原级+as”同级比较句型;能用比较级描述广州与温哥华的差异,并比较自己的城市与另一座城市。 学习能力 通过 3a 例句中黑体词的观察与归类,自主区分形容词比较级、副词比较级与同级比较;借助 3c 图表数据(人口、面积、年平均降雨量、1 月/7 月平均气温)选取恰当比较词完成句子。 思维品质 归纳“than 前后所使用的动词相同时,通常用助动词代替后面的动词,该助动词也可以省略”的规则;辨析 3b 中比较级问句与 as…as 同级比较问句的功能差异。 文化意识 借助广州与温哥华两座城市的数据比较,感受“用数据说话”的思维习惯,理解城市差异背后的地域文化;认识比较级在日常交流中帮助人们更清楚地描述差异的价值。 教学重难点 教学重点:①比较级的构成规则与不规则变化(Grammar Focus, 课本 p.25);②“比较级+than”句型及 much/a little/a lot/even 修饰语;③“as+形容词或副词原形+as”与“not as/so+原形+as”同级比较句型。 教学难点:①3b 中根据答语反推并写出问句(比较级问句与同级比较问句的选择);②3c 中用 that 指代 the population 及 It rains more…than…句型的表达;③than 后助动词的省略。 教学过程 教学环节 师生活动 活动观层次 评价要点 Step 1 歌谣导入 (3’) ①齐诵感知比较级:Grass gets greener. Days get warmer. Sun gets brighter. Dreams get bigger. Smiles get wider. Love gets stronger. It gets better.(更绿、更温暖、更亮、更大、更广阔、更强大、更好);②点题:本课系统学习比较级。 学习理解 感知与注意 歌谣跟读的语音质量(诊断性评价) Step 2 Work on 3a 观察发现 (7’) ①Read the sentences and notice the comparatives in bold. Find more examples in Section A.(p.25);②写出黑体单词的原级并归类——adj. 的比较级:many—more, colourful—more colourful, tall—taller, short—shorter;adv. 的比较级:well—better, loud—louder, early—earlier;同级比较:as tall as(as+原级+as)。 学习理解 获取与梳理 原级还原与归类正确率 Step 3 规则归纳 (8’) ①规则变化:一般在词尾加-er(tall→taller, short→shorter, loud→louder);以字母 e 结尾加-r;重读闭音节双写末尾辅音字母再加-er(big→bigger, thin→thinner);以“辅音字母+y”结尾变 y 为 i 再加-er(early→earlier, funny→funnier, lazy→lazier);多音节和部分双音节词前加 more(outgoing→more outgoing, colourful→more colourful, hard-working→more hard-working);②不规则变化:good/well→better, bad/badly→worse, many/much→more, little→less, far→farther。 学习理解 概括与整合 规则口诀的复述与例词对应(对应语言能力目标) Step 4 用法聚焦 (6’) ①“比较级+than”句型中,当 than 前后所使用的动词相同时,通常用助动词代替后面的动词,该助动词也可以省略——You know more about yourself than I (do).;②比较级前可以用 much, a little, a lot, even 等修饰——I'm feeling much better today. My brother is a little taller than me.;③“as+形容词或副词原形+as”表示双方在某方面相同(I think science is as important as maths. Tom runs as fast as Jack.);“not as/so+原形+as”表示一方在某方面不及另一方(It is not as/so warm today as yesterday. He did not come as/so early as Wang Lin.)。 学习理解 概括与整合 修饰语与同级比较句型的判断 Step 5 Work on 3b 问答操练 (8’) ①Use the words in brackets to write questions and answers.(p.25)——1. Q: Is Julie slimmer than you? A: No, she isn't. She is as slim as me. 2. Q: Are you as serious as your cousin? A: No, I'm not. I am more serious than he is. 3. Q: Is Tom smarter than Sam? A: No, I don't think so. I think Sam is as smart as Tom. 4. Q: Does Jack swim faster than Sally? A: No, he doesn't. He swims as fast as Sally.;②点拨:由答语中的比较级(more serious)或原级(as…as)反推问句类型;否定回答后接肯定的同级比较说明“其实一样”。 应用实践 内化与运用 3b 四组问答的准确率(对应思维品质目标) Step 6 Work on 3c 图表比较 (8’) ①Look at the chart. Then complete the sentences to compare Guangzhou and Vancouver. Use the words in the box and than.(p.25)——图表维度:人口、面积、年平均降雨量、1 月平均气温、7 月平均气温;②核对——1. The population of Vancouver was smaller than that of Guangzhou in 2024.(that 指代 the population)2. In area, Guangzhou is larger than Vancouver. 3. It rains more in Guangzhou than in Vancouver. 4. Guangzhou has a pleasant temperature in January. It is warmer than Vancouver in January. 5. Vancouver is cooler than Guangzhou in July.。 应用实践 内化与运用 3c 完成正确率;that 指代的理解 Step 7 迁移讨论 (4’) ①Discuss and say:Gina wants to visit a city in China. Which of the following cities do you think she may choose? Please use comparatives and “than” to explain your reasons.(Guangzhou / Hefei)——I think she can go to… The food there is more delicious than… And it is… than… She can… there. She will have a good time.;②追问:What are the benefits of using comparative degrees in daily life? —It helps us describe differences more clearly, like “My schoolbag is heavier than yours.” 迁移创新 想象与创造 城市推荐中比较级使用的准确性(表现性评价) Step 8 总结作业 (3’) ①Summary:Grammar——比较级的构成与用法、同级比较;Key words——slim, fact, population, km, average, pleasant(课本 p.25);Sentences——Emma is taller than Ella, but her hair is shorter than Ella's. / Emma always gets up earlier than me, but I work as hard as her! / The population of Vancouver was smaller than that of Guangzhou in 2024.;②布置分层作业。 迁移创新 概括与整合 笔记完整度 作业设计(分层) 【基础·必做】①熟读 3b 的问答;②抄写 Grammar Focus 表格中的句子(依据教材基础作业);③完成“巩固检测一”。 巩固检测一 用括号内所给单词的适当形式填空(课堂原题) 1. We all think Mike works __________ (hard) than Alan. 2. Don't you think our city is _______ (good) than before? 3. Which girl is _____________ (outgoing), your sister or your cousin? 4. After doing sports for months, Tina is becoming _______ (thin) than before. 5. Paul is not as _________ (popular) as Mary, but he is _________ (funny) than Mary. 【提升·选做】完成“巩固检测二”(依据教材提升作业)。 巩固检测二 动物对比(依据教材提升作业) 选择两种动物,从体型、速度、习性等方面用 5 个比较级句子进行对比描述,如 “The elephant is heavier than the tiger, but the tiger runs faster than the elephant.” 【拓展·挑战】完成“巩固检测三”(依据教材拓展作业)。 巩固检测三 城市对比介绍(依据教材拓展作业) 查找自己所在城市与另一座城市的人口、气温等数据,用比较级句型完成一段简短的对比介绍(至少 4 句话)。 巩固检测参考答案(供教师批阅) 一:1. harder(than 前用副词比较级) 2. better(good 的比较级) 3. more outgoing(多音节词前加 more) 4. thinner(双写 n 再加-er) 5. popular;funnier(not as…as 中用原级;but 后用比较级) 二:示例—The elephant is heavier than the tiger, but the tiger runs faster than the elephant. The tiger is smaller and more agile. It eats less than the elephant.(答案不唯一) 三:示例—My city is smaller than Shanghai, but the air is fresher. It is cooler in summer, and life is slower than in big cities.(答案不唯一) 板书设计 Unit 3 Same or Different? — Comparatives (II) 规则: +er / +r / 双写+er / y→i+er / 多音节前加 more 不规则: good/well→better bad→worse many/much→more little→less 用法: 比较级+than…(可被 much/a little/a lot/even 修饰) 同级: as+原级+as(相同) not as/so+原级+as(不及) 3c: The population of Vancouver was smaller than that of Guangzhou. In area, Guangzhou is larger than Vancouver. 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 语言能力目标 3b/3c 完成正确率;规则归纳的表述质量;巩固检测一完成质量 学习能力目标 黑体词观察归类与规则自主归纳的质量 思维品质目标 由答语反推问句的推理准确度;that 指代与 more rain 句型的理解 文化意识目标 用数据比较城市的表达;对比较级交流价值的认识 2. 预设反思点:①规则是否由学生先分类再归纳,避免直接呈现;②than 后助动词省略是否配对比例句;③3c 是否先读懂图表数据再选词;④检测一第 5 题原级与比较级混考是否作重点讲评。 学科网(北京)股份有限公司 $
