二、教材内容分析
本课时选自粤教沪外版(2024)七年级上册 Unit 1 School life 的 C Grammaring 板块,语法项目为 there be 句型。教材通过 Jane 课文和陈欣欣日记中的句子呈现语法现象:There is a boat school. / There are a lot of clubs and activities in our school.,引导学生观察并归纳 there is 与 there are 的用法。
教材语法要点明确:there is 接单数名词或不可数名词,there are 接复数名词;疑问句把 is/are 提到 there 前,如 Is there any water? — Yes, there is. / No, there is not.;用 How many … are there? 提问数量;there is 的缩写形式是 there’s。教材还配有一段关于新学校的短文填空,要求学生用 there is/are 补全(游泳池、小花园、42名学生、很多社团、美味菜肴)。
与第1课时阅读新授课不同,本课时是语法操练课:学生已在第1课时见过 there be 现象,本课时重心在规则归纳与多轮语用操练,学生开口时间不低于课时一半。
教材还给出否定形式:There isn’t any milk left. Let’s go and buy some.,以及就近引入新事物的用法。本课练习围绕新学校短文展开,话题与第1课时 Jane 的校园生活一脉相承,便于学生在熟悉语境中操练语法。
三、学情分析
经过第1课时,学生已能认读校园场所词汇,并在阅读中见过 there is/are 的例句,但尚未系统掌握单复数选择和疑问句式。七年级学生对语法规则的归纳能力尚弱,容易凭感觉误用 is/are;单纯讲解规则枯燥,需要借助图片、游戏和信息差任务让他们在使用中体会规则。学生喜欢竞赛和小组积分,适合用任务链驱动操练。
四、教学目标(核心素养导向)
【语言能力】
1. 能归纳并正确使用 there is + 单数/不可数名词、there are + 复数名词描述某处有某物。
2. 能熟练运用一般疑问句 Is there…? / Are there…? 和数量问句 How many … are there? 进行问答。
【文化意识】能借助 there be 句型对比介绍中外校园场所,体会校园环境之美。
【思维品质】通过观察例句归纳规则,发展从例子到规律的概括能力;通过信息差问答训练基于证据的提问与判断。
【学习能力】能在小组竞赛中互相纠错,主动用规则检查自己和同伴的句子。
五、教学重难点
教学重点:there is/are 的正确选用;Is there…? / Are there…? / How many…are there? 问答。
教学难点:不可数名词用 there is(如 There is some milk.);就近原则意识;How many 后接复数名词。
六、教学准备
教师:教室场所图片卡、学校场所磁贴、flashcard(单数/复数)、计时器、小组积分表、教材语法填空短文。
学生:课本、笔、一张画有“理想教室”的白纸。
七、教学过程
环节一 启动与激活(约5分钟)
【教师话术】Good morning, class! 上节课我们认识了 Jane 的美丽校园。Today let us talk about our classroom. Look around. What can you see? 今天我们来看看这间教室里有什么。
【教师活动】手指教室物品,快速带读单词卡:a book, two books, a desk, many desks, a clock。重点提示单复数。
【学生预设】I can see a book / two desks / a clock.
【关键提问】当我们说“一个书包”用 a schoolbag,“两个书包”呢?two schoolbags. 单数和复数不一样,be 动词怎么选?
【设计意图】用教室真实物品激活单复数概念,为归纳 there is/are 做铺垫。
环节二 语境建构与规则归纳(约10分钟)
【教师话术】Open your book. Look at the blue sentences. There is a dining room on the first floor. There are two teaching buildings in our school. 请大家观察标蓝的句子,猜猜:什么时候用 there is,什么时候用 there are?
【教师活动】板书两个例句,用彩色粉笔圈出 is / are 和后面的名词(单数 a dining room / 复数 two teaching buildings)。
【学生预设】后面是一个东西用 is,很多东西用 are。
【教师小结】There is + 单数或不可数;There are + 复数。再补充不可数:There is some milk.(milk 不可数,仍用 is)。疑问句把 is/are 提前:Is there a library? How many labs are there?
【关键提问】There ___ some water in the bottle. There ___ five labs.(is 还是 are?)
【学生预设】There is some water.(water 不可数);There are five labs.
【设计意图】从教材例句出发,让学生自己发现规则,而非教师直接灌输。
【板书提示】中央画句型树:there is + 单数/不可数;there are + 复数;疑问句 Is there…? / Are there…? / How many…are there?
环节三 多轮内化运用任务(约20分钟,核心操练)
任务1 听音辨句。【教师话术】Listen carefully. 老师读句子,你判断是 there is 还是 there are,听到 is 举左手,听到 are 举右手。
【教师活动】读:There is a club. / There are many students. / There is some bread. / There are three buildings.
【教师提示】Listen carefully. 听清句末是 is 还是 are,不要抢答。第一次慢,第二次加快速度。
【学生活动】快速举左右手。预设回答多样:有的学生听到 There is some water 时犹豫——教师提示 water 不可数,仍用 is;出错的学生自己纠正,同桌可以小声提醒。
任务2 闪卡快速配对。【教师话术】Here are picture cards. 抽一张图,两人一组用 There is/are 说句子,说得又快又对得分。
【学生预设】There is a library. / There are two footballs. / There is a canteen.
【教师追问】Look at this card. 一张图里既有一本书又有两个球,怎么说?引导学生合并:There is a book and there are two balls.
【学生预设】There is a book and there are two balls.(基础弱的学生先说 There is a book. 再补充 There are two balls.)
任务3 信息差问答 Guess what is in the classroom.【教师话术】Pair A 看图不让 B 看,B 用 Is there…? 来猜。A 用 Yes, there is. / No, there is not. 回答。
【学生活动】S2: Is there a TV in the picture? S1: No, there is not. S2: Is there a computer? S1: Yes, there is.
任务4 连锁操练 Chain drill。【教师话术】Let us make a chain. S1: There is a library in our school. S2: There is a library and there are many classrooms. 每人加一样东西。
【学生活动】学生依次累加:There is a library. There are many classrooms. There is a big playground. There are three labs.
任务5 数量问答。【教师话术】How many classrooms are there in our school? 数一数,问答。
【学生预设】There are twenty classrooms. / How many teachers are there? There are about thirty.
任务6 改错小医生。【教师话术】Here are three sentences with mistakes. 老师故意写错三句,请小医生们把错处找出来并改正:There is many books. / There are a library. / How many book are there?
【学生预设】There are many books. / There is a library. / How many books are there?(book 要加 s,are 要搭配复数。)
【关键提问】How many 后面的名词要用单数还是复数?为什么?
【学生预设】要用复数,因为问的是数量,不止一个。
【设计意图】六个任务从听辨、看图说话、信息差、连锁、数量问答到改错,层层递进,学生开口时间占课时一半以上,在使用中内化规则;改错任务让学生站在评判者角度巩固规则。
【板书提示】右下角贴小组积分表:第一组/第二组/第三组,每答对一题加分。
环节四 真实迁移输出(约5分钟)
【教师话术】Now draw your dream school on the paper. 画你理想中的学校,用 there is/are 写三句话介绍。
【学生预设】There is a big swimming pool. There are many books in the library. There is a zoo in my school.
【关键提问】Why do you like your dream school?
【设计意图】从句型操练迁移到真实表达,为 E Writing 写校园句子铺垫。
环节五 梳理与反馈(约5分钟)
【教师话术】What is the rule? 谁来总结:there is 接什么,there are 接什么?
【学生活动】学生齐读句型树;教师公布小组积分,表扬获胜组。
【设计意图】回扣规则,用积分反馈课堂表现。
八、板书设计
主板书为 there be 句型树:中央写 There be,左枝 There is + 单数/不可数(a library / some milk),右枝 There are + 复数(many clubs / five labs);下方写疑问句 Is there…? — Yes, there is. / No, there is not.;How many … are there? — There are …。右下角贴小组积分表(三组,逐题记分)。
九、作业设计
【基础达标】
1. 用 there is/are 填空:There ___ a book on the desk. There ___ thirty students in our class. There ___ some water in the bottle. There ___ five clubs.
2. 把下列句子改为一般疑问句并作肯定、否定回答:There is a library. / There are two labs.
【巩固提升】
3. 仿照教材短文,用 there is/are 写五句话介绍自己的教室。
【拓展挑战】
4. 写一段话描述你的理想学校,至少用三次 there is/are,下节课分享。
5.(选做)用 Is there…? / Are there…? 采访一位家人:Is there a park near your home? 记录回答并下节课汇报。
附:常见错误预判与纠正策略
错误1:不可数名词误用 are,如 There are some water. 纠正:用实物演示一杯水,强调 water 看不见一个个杯子,是不可数,用 is。
错误2:How many 后接单数名词,如 How many book. 纠正:强调 how many 问数量,后面名词一律加 s,并带读 How many books are there?
错误3:疑问句句序错,如 Are there a library? 纠正:回到句型树,单数用 Is there,复数用 Are there,先看名词单复数再选动词。
错误4:就近原则混淆,如 There is two books and a pen. 纠正:本单元暂不强调复杂就近,先训练学生紧看紧跟在 be 动词后的第一个名词。
十、教学反思(预设)
可取之处:以教室真实物品导入,五轮任务链让学生在游戏和信息差中高频操练 there is/are,规则由学生自己归纳。
可能不足:不可数名词仍有学生误用 are;连锁操练时后进学生跟不上节奏。
改进方向:不可数名词用 more examples(water, milk, bread)强化;连锁操练允许同伴提示,积分时对后进组适当降低难度。
