Unit 5 Lesson 6 Great Inventions of Ancient China教学设计
一、教学目标:
语言知识目标:
能理解并运用与发明相关的核心词汇:abacus, calculate, tofu, protein, mineral, porcelain, trace back to, be discovered by。
能掌握描述发明历史、特点、影响的句型:It was invented in...; It is a good source of...; It is said that...; The origins can be traced back to...。
阅读技能目标: 能通过略读(skimming)获取文章主旨(介绍多种中国古代发明),通过扫读(scanning)定位特定发明的具体信息(如时间、人物、特点)。
文化意识与思维目标: 了解中国古代除四大发明外的其他重要创造,认识其对世界文明与日常生活的贡献,增强文化自豪感。
二、教学重难点
教学重点: 准确获取并转述算盘、豆腐、茶、瓷器、丝绸五种发明的关键信息。
教学难点: 理解并运用“trace back to”, “a good source of”, “it is said that”等表达;有条理地介绍一项发明。
三、教学过程:
Step 1: 导入与预测 (Lead-in & Prediction) – 功能:激活背景知识,明确学习主题
头脑风暴: 提问:What are the “Four Great Inventions” of ancient China? 【预设学生反应】:大部分学生能说出“paper, printing, gunpowder, compass”的中文或英文。
【教师应对预案】:板书并确认英文,并说明:They are very famous. But today, we’re going to learn about OTHER great inventions from ancient China.
图片预测: 依次快速展示教材中算盘、豆腐、茶、瓷器的图片(遮盖文字)。提问:What are they? Do you know their English names?
【预设学生反应】:能说出中文名,但英文名可能不熟(如tofu, porcelain)。
【教师应对预案】:教授新词“abacus, tofu, porcelain”,并提问:What do you know about them? (e.g., How old is it? What is it for?) 引导学生简单猜测。
揭示任务: 告知学生,本节课将通过阅读,完成一个“发明信息卡”,为介绍最喜欢的中国古代发明做准备。
Step 2: 阅读与探究 (While-reading) – 功能:理解文章细节,完成信息提取
首次阅读,验证预测:
学生快速默读全文,核对在导入环节对图片的猜测是否正确。
完成教材活动
1:Read the passage and answer the questions. (问题需教师根据文章内容自行设计,例如:1. How many inventions are mentioned? 2. What are they? 3. Which is the oldest?)
二次阅读,完成信息卡(精读):
学生再次仔细阅读。教师发放或投影“发明信息表”,引导学生分组或独立完成。
Invention
How old? / When?
Key Features / Uses
How was it invented/found?
Abacus
over 2,500 years ago
tool for merchants/bankers to calculate
(未提及)
Tofu
over 2,000 years
good source of protein, rich in minerals
(未提及)
Tea
(未明确)
popular drink
discovered by Shennong (accident)
Porcelain
Han Dynasty
beautiful, famous export
(未明确)
Silk*
(从练习E推断)
from silkworm cocoons
(通过丝绸之路闻名)
(注:Silk信息需从练习E及学生常识中补充)* 教师巡视,指导学生定位关键句,并解释“primary tool”, “a good source of”, “origins can be traced back to”, “it is said that”等短语。
3. 核对与语言聚焦:* 集体核对信息表。* 聚焦重点句型,进行机械性操练。例如:* It was invented in China over 2,500 years ago.* It is a good source of protein.* It is said that Shennong discovered tea.* The origins can be traced back to the Han Dynasty.
Step 3: 分层巩固练习 (Post-reading Practice) – 功能:巩固课文内容与语言点,分层训练练习题设计如下:
I. 基础奠基 (全班达标)完成教材活动2:Read the passage again and fill in the blanks.(此练习完全直接对应原文,用于检测基本信息理解)
II. 能力进阶 (80%学生可做)根据课文信息,将发明与其描述连线。
Abacus A. It was discovered accidentally by an ancient emperor.
Tofu B. Its history started during the Han Dynasty.
Tea C. It helps people do maths quickly.
Porcelain D. It is healthy because it provides protein and minerals.
【预设学生反应】:学生需理解描述,而非照抄原词。C项描述是“helps people do maths quickly”,文中原话是“tool... to calculate”,需一步同义转换。
【教师应对预案】:核对答案时,引导学生找出文中对应句,理解“calculate”即“do maths”。
II. 拓展选做 (*)思考与表达:除了文中提到的,你还知道哪些中国古代的伟大发明?(例如:kite, umbrella, paper money...)请用“It was invented in ancient China. It was used for...”的句型简单介绍其中一个。【预设学生反应】:学生可能用中文说出名称。
【教师应对预案】:鼓励尝试英文,并提供“kite, umbrella”等词汇支持,重点评价句式的运用。
Step 4: 小结与输出准备 (Summary & Output Prep) – 功能:总结归纳,为介绍发明做准备
回顾总结: 利用板书或信息表,教师带领学生回顾:“Today we met five great inventions: ... We know their history, features and stories.”
输出任务导入:
引出教材活动3的表格框架,说明下一任务:介绍一项发明(可以是中国的,也可以是其他国家的)。
课堂启动: 学生两人一组,从课文介绍的五个发明中,选择其中一个作为练习对象。利用本课完成的“发明信息表”,尝试用3-4句话向同伴介绍它。教师提供语言支架:
This is the abacus. It was invented in China over 2,500 years ago.
It was the primary tool for merchants to calculate.
I think it is amazing because it’s very old but useful.
作业布置:
(必做)熟读课文,并完成教材活动2的填空题。
(必做)完善课堂上对所选发明的3-4句介绍,并背诵。
(选做/为下节课准备)思考一项你想介绍的其他发明(来自任何国家),并查阅它的基本信息(名称、国家、时间、影响)。
