Unit 6 Nature and us Part B 教学设计
一、核心素养目标
1. 语言能力:掌握Part B核心词汇(forest, river, lake, mountain, hill, tree等)及句型There is/are...,能运用句型描述自然景物的位置与数量,完成听说读写综合语言任务。
2. 思维品质:通过观察图片、情境对话、话题讨论,培养观察分析、逻辑表达能力,能围绕自然话题梳理语言逻辑,实现从输入到输出的思维转化。
3. 文化意识:了解中西方对自然景物的描述习惯,感受自然之美,培养热爱自然、保护自然的共同情感,树立跨文化语境下的环保理念。
4. 学习能力:掌握“情境感知-句型操练-话题运用”的学习方法,能主动参与小组互动,学会合作探究,提升自主运用语言解决问题的能力。
二、教学重难点
(一)教学重点
1. 熟练掌握Part B核心词汇,能准确认读、拼写并运用到语境中,区分hill与mountain、lake与river的语义差异。
2. 掌握There be句型的肯定句、否定句及一般疑问句结构,能运用句型There is/are...描述自然景物的存在,正确搭配单复数名词。
3. 能听懂关于自然景物的简短对话,完成信息获取任务,并用核心句型进行情景对话、话题描述,实现语言的灵活运用。
(二)教学难点
1. 正确运用There be句型的主谓一致原则,区分There is(接单数名词/不可数名词)与There are(接复数名词)的用法,避免单复数搭配错误。
2. 能在真实情境中灵活运用核心句型描述自然景物,实现从机械操练到自主表达的过渡,提升语言输出的准确性与流畅性。
3. 结合自然话题,将词汇、句型与环保理念融合,用英语表达保护自然的简单观点,实现语言工具性与思想性的统一。
(三)重难点突破策略
1. 情境具象法:创设自然公园、郊外景区等真实情境,通过图片、视频、实物道具,让学生直观感知词汇与句型的用法,突破主谓一致难点。
2. 梯度操练法:从词汇跟读、句型机械操练,到情境对话、话题仿写,逐步推进语言学习,通过师生、生生互动强化句型运用,提升表达流畅度。
3. 任务驱动法:设计信息匹配、对话创编、话题展示等任务,让学生在完成任务的过程中运用语言,结合环保话题实现知识与情感的融合。
三、教学过程
(一)情境导入,激活旧知
1. 情境创设:播放自然风景视频(森林、河流、山脉、湖泊等场景),搭配轻快的背景音乐,展示对应景物图片,提问:Boys and girls, look at these beautiful pictures. What can you see in them Do you like these natural scenes
2. 师生互动:引导学生用已学词汇自由表达,教师补充Part B核心词汇,板书并领读forest, river, lake等,通过图片对比区分hill(小山)与mountain(大山)、lake(湖泊)与river(河流)的差异,激活学生旧知,引发学习兴趣。
3. 导入新知:明确本节课核心内容——掌握自然景物词汇,学习There be句型,能用句型描述自然景物,学会用英语谈论自然并表达环保观点。
(二)探究新知,层层递进
1. 词汇探究:夯实基础,辨析差异
(1)词汇学习:
① 教师结合图文教具,逐一讲解核心词汇:forest(森林)、river(河流)、lake(湖泊)、mountain(高山)、hill(小山)、tree(树)、flower(花),领读单词,强调发音要点(如mountain的重音位置、river的尾音发音)。
② 语义辨析:通过对比图片,明确hill与mountain的差异(hill海拔较低、坡度较缓,mountain海拔高、坡度陡);lake与river的差异(lake是静止的水域,river是流动的水域),结合例句帮助学生理解:There is a small hill near the lake. There is a high mountain beside the river.
③ 互动操练:开展单词接龙、看图说词游戏,小组内互相抽查单词认读与拼写,教师巡视指导,纠正发音与拼写错误,夯实词汇基础。
2. 句型探究:突破难点,灵活运用
(1)句型呈现:
① 教师展示自然公园图片,指着图片说:Look! There is a lake in the park. There are some trees near the lake. 板书句型There is/are...,讲解句型结构:There is + 单数名词/不可数名词 + 地点状语;There are + 复数名词 + 地点状语,强调be动词的单复数搭配规则。
② 否定句与疑问句:结合例句推导否定句There isn't/aren't...和一般疑问句Is there... / Are there... 及回答Yes, there is./No, there isn't. Yes, there are./No, there aren't. 板书例句:There isn't a river in the park. Is there a mountain near here Yes, there is.
(2)梯度操练:
① 机械操练:教师出示不同景物图片,引导学生用There is/are...造句,先集体操练,再指名发言,纠正单复数搭配错误,强化主谓一致原则。
② 互动问答:开展师生、生生问答练习,如教师问:Is there a lake in your school 学生回答;小组内互相提问:Are there any trees near your home 轮流回答,熟练掌握疑问句用法。
③ 情境创编:给每组发放不同自然场景图片(如郊外、森林、湖边),小组合作创编简短对话,运用There be句型描述场景,每组推选代表展示对话,教师点评优化。
3. 语篇探究:整合运用,提升能力
(1)听力训练:
① 播放教材Part B听力材料,要求学生听录音,圈出听到的词汇,完成信息匹配任务(将景物与位置对应),培养学生信息获取能力。
② 再次播放录音,让学生跟读,模仿语音语调,理解对话含义,提取核心句型,教师讲解听力中的难点句子,帮助学生梳理语篇逻辑。
(2)话题表达:
① 教师引导学生结合自身经历,谈论去过的自然景点:Where have you been What can you see there 鼓励学生用There be句型描述景点中的景物,结合词汇丰富表达。
② 小组讨论:围绕Protecting nature话题,讨论如何保护自然景物,用简单英语表达观点,如We should plant more trees. We shouldn't pollute the river. 教师补充环保相关表达,实现语言与情感的融合。
(三)巩固练习,深化运用
1. 基础巩固:句型仿写与词汇运用
(1)任务:给出自然场景提示(如a forest, two lakes, some mountains),让学生用There be句型的肯定句、否定句及疑问句仿写句子,每组完成5个句子,教师抽查批改,纠正错误。
(2)互动反馈:指名学生展示仿写句子,师生共同点评,重点纠正单复数搭配、介词运用错误,强化句型掌握。
2. 情景应用:对话创编与展示
(1)任务:创设情境——假设你和朋友去自然公园游玩,创编一段对话,运用核心词汇和There be句型谈论公园中的景物,询问对方是否喜欢,对话不少于5句。
(2)小组合作:每组2-3人创编对话,教师巡视指导,帮助学生优化表达,然后每组推选代表上台展示,师生点评,评选最佳对话小组,提升学生语言输出能力。
3. 拓展练习:话题写作与分享
(1)任务:让学生写一段短文,描述自己喜欢的自然场景(如森林、湖边、山区),运用There be句型描述景物,不少于5句话,可适当加入环保观点。
(2)分享点评:学生完成后,小组内互相交流修改,然后指名学生朗读短文,教师点评,肯定优点,纠正语法与表达错误,培养学生写作能力。
(四)课堂小结,反思提升
1. 核心知识归纳
(1)词汇:梳理Part B核心词汇,强调hill与mountain、lake与river的语义差异,回顾单词拼写与发音要点。
(2)句型:总结There be句型的结构,重申There is与There are的用法区别,否定句、疑问句的变化规则及回答方式,强化主谓一致原则。
(3)运用:回顾如何用核心词汇和句型描述自然景物,表达环保观点,梳理“词汇-句型-话题”的运用逻辑。
2. 反思与感悟
(1)引导反思:通过今天的学习,你掌握了哪些词汇和句型?在运用There be句型时,你还存在哪些困难?如何在生活中用英语谈论自然话题?
(2)感悟提升:Nature is beautiful and important to us. We should use English to share the beauty of nature and tell others to protect it. 希望同学们在今后的学习中,主动运用英语,热爱自然、守护自然,做环保小卫士,同时不断提升自己的英语语言能力。

六、答案与解析
(一)单选题答案
1. A 2. B 3. C 4. B 5. B 6. B 7. A 8. B
(二)解析
1. 解析:There be句型遵循就近原则,靠近be动词的a high mountain是单数名词,故用is;are用于复数名词前,am只与I搭配,be是原形,均不符合,故选A。
2. 解析:由答句But there is a big lake可知,森林里没有河流,问句主语a river是单数,否定回答用No, there isn't;A项表示肯定,C、D项搭配复数名词,均不符合,故选B。
3. 解析:many后接复数名词,tree的复数是trees;flower、mountain是单数,不符合many的用法,故选C。
4. 解析:any后接复数名词或不可数名词,river是可数名词,复数形式为rivers;A、C、D项均为单数名词,不符合any的用法,故选B。
5. 解析:答句中some flowers是复数名词,故用there are;A、C项搭配单数名词,D项表示否定,均不符合语境,故选B。
6. 解析:a lot of animals是复数名词,There be句型中复数名词前用are;has/have表示拥有,不能与There be句型混用,故选B。
7. 解析:结合语境,小山在湖附近,走路能到达,near表示在附近;in在里面,on在上面,under在下面,均不符合语境,故选A。
8. 解析:句意是保护自然不应污染河流,要保持清洁,pollute表示污染;plant种植,protect保护,love热爱,均不符合句意,故选B。
