核心素养目标
素养维度 目标描述
语言能力 识别并正确构成形容词、副词的最高级(-est / 双写-est / 变 y 为 i-est / the most;不规则 good/well—best, bad/badly—worst, many/much—most, little—least, far—farthest);掌握“主语+be+the+最高级+in/of 短语”“one of the+最高级+可数名词复数”“疑问词…, A, B or C ”“the+序数词+最高级”及“比较级+than anyone/any other…”隐含最高级等句型;能用最高级描述自己最喜欢的物种并完成银杏短文填空。
学习能力 通过 3a 黑体词写出原级并归类规则;借助词典完成 2b 类后缀名词练习前的规则预习;利用银杏(ginkgo)千年古树的背景信息辅助 3c 语篇理解。
思维品质 辨析最高级句型中 in(接单位/场所)与 of(接一群人或事物)的范围差异;理解“more than+anyone/any other…”用比较级表达最高级含义的逻辑转换。
文化意识 了解终南山千年银杏(唐太宗于公元 628 年手植,约 1400 年树龄)的文化故事;体会以生动的方式发现和赞美大自然中的动植物,加深对世界多样性的热爱和敬畏。
教学重难点
教学重点:①最高级的构成规则与不规则变化(Grammar Focus, 课本 p.35);②六大常用句型(the+最高级+in/of 短语;one of the+最高级+复数名词;选择疑问式;序数词+最高级);③3b 五句与 3c 银杏语篇的最高级填空。
教学难点:①in 与 of 比较范围介词的选择;②“比较级表最高级”(He runs faster than anyone in his class.)的语义转换;③3c 中 the most ancient / the best time to see it 等语境化选词。
教学过程
教学环节 师生活动 活动观层次 评价要点
Step 1 视频导入 (3’) ①观看动植物之最短视频,激活最高级旧知;②点题:本课系统学习最高级(superlative)。 学习理解 感知与注意 旧知复现情况(诊断性评价)

Step 3 定义与规则 (8’) ①定义:当对三者或三者以上的人或事物进行比较,表示“最……”的含义时,需要用最高级;形容词最高级前面必须加定冠词 the,副词最高级前的 the 可以省略;②规则变化:一般在词尾加-est(tall→tallest, fast→fastest);以字母 e 结尾加-st(large→largest);重读闭音节双写末尾辅音字母再加-est(big→biggest);以“辅音字母+y”结尾变 y 为 i 再加-est(heavy→heaviest, early→earliest);多音节和部分双音节词前加 the most(useful→the most useful, interesting→the most interesting, popular→the most popular);③不规则变化:good/well→best, bad/badly→worst, many/much→most, little→least, far→farthest。 学习理解 概括与整合 规则复述与例词对应(对应语言能力目标)
Step 4 六大句型 (9’) ①“主语+be+the+形容词最高级+in/of 短语”——Tom is the tallest in his class/of all the students.;【注意】in 后一般接表示单位或场所的名词;of 后一般接表示一群人或事物的代词或名词;②“主语+实义动词+(the)+副词最高级+in/of 短语”——I jump (the) farthest in my class/of all the students.;③“主语+be+one of the+形容词最高级+可数名词复数+in/of 短语”——Beijing is one of the largest cities in China.;④“疑问词(组)+be+the+形容词最高级, A, B or C ”用于三者比较——Which country is the largest, China, Brazil or Canada ;⑤“疑问词(组)+助动词+主语+动词原形+(the)+副词最高级, A, B or C ”——Which season do you like (the) best, spring, summer or autumn ;⑥“主语+be+the+序数词+形容词最高级+可数名词单数+in/of 短语”——The Yellow River is the second longest river in China.;⑦比较级表最高级:当句子中出现 (more) than+比较范围(如 anything, anyone, any other…)时,常隐含最高级含义——He runs faster than anyone in his class.(他比班上任何人都跑得快→他是班上跑得最快的。) 学习理解 概括与整合 in/of 范围介词的判断;句型配对
Step 5 Work on 3b 填空操练 (7’) ①Complete the sentences with the superlative forms of the words in brackets.(p.35)——1. Among all animals, I love pandas the best.

Step 6 银杏铺垫 3c 语篇 (8’) ①Look and say:Do you know what tree it is —ginkgo(n. 银杏);It is one of the oldest living trees on earth.

Many Chinese believe that the old ginkgo tree in the Zhongnan Mountains in Shaanxi Province is the most beautiful. Thousands of tourists come to see it each year, especially in mid-October, as it is the best time to see it.
