第一幕：激活与诊断 (0-8分钟)
1. 目标导入与错误诊所
“Good morning, everyone! 上节课我们学习了优秀引言的’配方’。今天，我们化身’写作医生’，在写作手术室里，借助AI助教 IMA 的帮助，给我们的引言做个手术，让它不仅正确，而且强力、够得上7分！”
错误诊所活动 (3分钟)
题目 (Question): The graph below shows the proportion of the population aged 65 and over between 1940 and 2040 in three different countries.
问题引言 (Patient Intro):
小组任务 (60秒): 在你的小组中，用60秒诊断出这个“病人”（引言）的所有“病症”。它到底哪里出问题了？
教师总结:
- 语法 (Grammar): “The graph illustrate” -> The graph illustrates
- 词汇 (Vocabulary): “old people” -> people aged 65 and over; “three country” -> three countries
- 改写 (Paraphrasing): 直接照抄 “from…to…” -> 应改写为 over a 100-year period from 1940 to 2040
- 清晰度 (Clarity): 缺少关键信息（国家名称）。
7分范例 (Band 7 Model):
“The line graph illustrates the percentage of people aged 65 and over in three countries, namely Japan, Sweden, and the USA over a 100-year period from 1940 to 2040.”
对比强调: “看到区别了吗？我们今天的目标，就是每次都能写出第二种这样的句子。”
第二幕：人机协作练习 (8-28分钟)
2. 第一轮练习：线图 + IMA反馈
Task 1 (Line Graph)
The line graph below shows changes in the consumption of fast food in the UK between 1970 and 2010.
Summarise the information by selecting and reporting the main features.
“请现在写出你的单句引言。你有3分钟时间。记住关键要素！”
IMA 的反馈
预估: 6.0
点评: 这个句子抓住了主要信息，但缺少高质量的同义词替换。例如，直接使用了”changes”和”consumption”。
- 同义替换 (Paraphrasing): 中等水平。可以尝试用 ‘shifts’ 或 ‘trends’ 替换 ‘changes’。
- 准确性 (Accuracy): 良好。关键信息（快餐，英国，1970-2010）都已包含。
- 清晰度 (Clarity): 良好。句子结构清晰。
💡 7分优化版本: “The line graph illustrates shifts in the weekly consumption of different types of fast food by people in the UK over a 40-year period from 1970 to 2010.”
2.5. 第二轮练习：表格题 + IMA反馈
Task 1 (Table)
The table below shows the proportion of income adults and children spent on different items in one European country in 2015.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
“很好，我们来试试另一种常见的图表——表格。同样，写出你的引言，然后让IMA帮你看看。”
IMA 的反馈
预估: 6.5
点评: 句子结构清晰，但可以更好地改写’proportion of income’和’spent on different items’。
💡 7分优化版本: “The table illustrates the spending patterns of adults and children on five distinct categories in a European nation in 2015, showing the percentage of their income allocated to each.”
3. 小组研讨与策略总结
小组讨论 (5分钟): 和你的同伴分享IMA的反馈，讨论以下问题：
- “IMA给了你多少分？”
- “丢分的主要原因是什么？”
- “优化版本里哪个词或短语最有用？”
7分引言成功公式
- 图表类型: The [line graph/bar chart/pie chart]…
- 强力动词: illustrates / demonstrates / gives information about / compares…
- 改写主题: changes in fast food consumption → shifts in the popularity of convenience foods
- 包含细节: in the UK → in the United Kingdom; between 1970 and 2010 → over a 40-year period from 1970 to 2010.
第三幕：巩固与挑战 (28-38分钟)
4. 第二轮限时挑战：饼图
Task 1 (Pie Charts)
The pie charts below show the proportion of energy produced from different sources in a country in 1985 and 2003.
Summarise the information by selecting and reporting the main features.
“新挑战！你只有 **90秒** 为这个饼图写引言。开始！检查你的分数有没有提高！”
IMA 的反馈
预估: 7.5
点评: 非常出色！这个句子准确地使用了 “compares” 来处理两个图表，并且成功改写了时间和其他关键词。
- 同义替换 (Paraphrasing): 高水平。使用了 ‘proportion’ 和 ‘sources’ 等词。
- 准确性 (Accuracy): 极好。所有关键信息都得到了精确的呈现。
- 清晰度 (Clarity): 极好。句子结构流畅、专业。
💡 7.5分参考版本: “The two pie charts compare the percentages of energy generated from five different sources in a particular nation in the years 1985 and 2003.”
4.5. 进阶挑战：地图题
Task 1 (Maps)
The maps below show the village of Stokeford in 1930 and 2010.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
“地图题是特殊题型，重点在于描述变化。写下你的引言，看看IMA怎么说。”
IMA 的反馈
预估: 7.0
点评: 优秀的引言！清晰地指出了图表类型、地点和时间跨度。动词 ‘depict’ 使用得很好。
💡 7.5分参考版本: “The two maps depict the significant transformations that the village of Stokeford underwent over an 80-year period, between 1930 and 2010.”
4.6. 高难度挑战：混合图表
Task 1 (Mixed Charts)
The first chart below shows how energy is used in an average Australian household. The second chart shows the greenhouse gas emissions which result from this energy use.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
“混合图表需要我们一句话概括两个图的关系。这是高分关键，来试试！”
IMA 的反馈
预估: 7.0
点评: 成功地将两个图表的信息整合到了一句话中。可以考虑用一个更强的词来连接两个图表的关系。
💡 8.0分参考版本: “The pie chart illustrates the primary uses of energy within a typical Australian home, while the second chart details the corresponding greenhouse gas emissions produced by each of these applications.”
第四幕：总结与展望 (38-40分钟)
终极毕业挑战：流程图
Task 1 (Process Diagram)
The diagram below shows the process of cement production.
“作为今天的毕业挑战，我们来看看流程图。流程图的引言最考验’概括’能力。写下你的版本，为今天的学习画上完美句号！”
IMA 的反馈
预估: 7.5
点评: 极佳！使用了被动语态 ‘is illustrated’，并且准确地概括了图表的核心内容’how cement is produced’。
💡 8.0分参考版本: “The diagram illustrates the various stages involved in the process of producing cement.”
5. 目标回顾与课后任务
