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.
