By the end of the lesson, students will be able to:
review the genre knowledge of the news report by awakening previous knowledge；

2. Develop cultural awareness, cross-culture communication abilities and global competence.
III. Predicted area of difficulty
1. Clear up the logical sequence of the contents through detailed analysis and then generalize the hidden logical rules.
IV. Teaching procedures
Step 1 Background awareness: stimulating reading interest and awakening cultural knowledge
T guides students to recite the Chinese version of the poem from The Book of Songs after presenting the English version.
What is the corresponding Chinese translation of this poem
Can you find something special in this poem related to the passage today (sort of destined relationship between Tu Youyou and qinghaosu)
T asks students their knowledge about Tu Youyou.
How much do you know about this great woman’s background Birthyear and birthplace Major and career What about her main contributions
【设计意图：用《小雅·鹿鸣》这首诗歌的中英文版本导入，学生得以一探屠呦呦和青蒿素冥冥之中的不解情缘，感悟各自名字所蕴含的偶然巧合和必然期望，描绘本节课的文化底色，激发阅读兴趣。其次，以标签的视觉形象，提炼关于人物的背景知识，揭开人物的面纱，逐步走进人物形象。】
Step 2 Structure analysis: reviewing genre knowledge of the news report
1. T asks students the text type of this passage and describe the general features of this text type
What is the most typical feature of this genre (inverted pyramid)
What can this genre be divided into (lead, body and tail)
【设计意图：语篇类型是英语课程的六大要素之一，语篇知识是构成学生语言能力的重要基础。这篇文本具有鲜明的新闻体裁的特点，学生在之前的英语学习过程中对新闻体裁已有所了解，激活并巩固新闻报道常见结构等语篇知识是必修课程阶段重要内容要求之一。】
Step 3 Content analysis: skimming for the main idea of each part and explaining how to find it.
T presents the 4 parts of this passage and asks students to generalize the main idea of each part, employing the first paragraph as the example.
What is the main idea of this part and where do you find the answer (Tip: finding topic sentence)
If Part. 1 shows the most important information in this passage, what about other parts
Again, what sequence do the information in these parts follow (inverted pyramid)
【设计意图：学生的学习能力的发展离不开学习策略的有效使用。通过扫读获得篇章具体信息是实践认知策略的表现，因此在授课过程中注重基于语篇归纳内容大意，能够帮助学生在自主学习过程中实现该策略的正向迁移。】
Step 4 In-depth analysis: summarizing Tu Youyou’s qualities, generalizing her research procedures and clarifying her contributions
T asks students to match the problems faced during Tu’s experiment and the solutions springing to her mind.
T offers 7 adjectives and asks students to choose 5 ones that can best describe Tu.
Could you correct the other adjectives
Where are your choices based on Would you apply the details in the passage to back up your choice (numbers, verbs, adverbials)
T provides 4 choices and asks students to choose the one which best describes Tu’s experimental procedures.
T presents 4 line charts and asks the choose the one which best describes Tu’s experimental process.
After the preparations, T invites one student to retell Tu’s experimental procedures with the aid of previous two charts.
What conclusion can you draw from them (through trial and error; a continuing upward spiral of progress; …)
Any other aspects in our daily life developing following this process (CTM, our country, our world, ourselves, …)
T asks students to focus on Tu’s contributions of the discovery of qinghaosu and fill in the blanks on the basis of the last part.
Tu and her team’s efforts finally paid 1. ___. Qinghaosu, the most 2. e________(effect) part of qinghao extract and the key part of many malaria medicines, has since benefited about 200 million malaria patients, increasing their chance of 3. ________(survive). Eventually, Tu 4. ____________(award) the Nobel Prize in Medicine, 5. __________(become) the first Chinese woman 6. _______(win) it. In Tu’s Nobel Lecture, she encouraged scientists to make further 7. __________(explore) of the treasure house of traditional Chinese medicine and approach the 8. _______(wise) of it, 9. _______ will be 10. _________(benefit) to global health care.
Can you generalize Tu’s major contributions (the discovery of qinghaosu saves many people’s lives and won her a Nobel Prize)
Besides these, what other contributions has Tu made (earn international recognition for Chinese scientists; offer inspiration to female scientists; …)
【设计意图：表面上，此过程中对如前所述的文章第三部分和第四部分进行分析，实则把文章内容重组为qualities; procedures; contributions三个方面，破除了结构性知识带来的桎梏，对“屠呦呦的人物品质、发现青蒿素的实验过程以及屠呦呦这一发现的成就”逐一进行分析，为接下来的总结升华活动搭建支架。设置内容配对、七选五、单项选择、复述、语法填空等多种学习活动，从梳理、概括、分析、批判、表达等多个维度由浅入深全方位综合性考查学生的思维品质。文章内容的分析围绕屠呦呦展开，重点介绍屠呦呦团队发现青蒿素的过程，刻画了他们不懈努力、无私奉献的人物形象，由此屠呦呦成为了中国第一位获得诺贝尔奖的女科学家，揭示了中国传统中医药学的智慧，由中国人物到中国“智”造，于无形中增强学生的文化自信。】
Step 5 Critical thinking: deepening the understanding of the significance of qinghaosu and the hidden awareness.
Chances are slim that the malaria will break out in China, thus some people find it hard to understand the contributions of qinghaosu. What is your opinion
Let’s reflect on the whole new report again Do you think this discovery can be made by one person, solely humans and one parts of the Earth
Consequently, what message can we draw from it
【设计意图：回溯屠呦呦及其团队发现青蒿素的过程，明晰文章的暗线，厘清过程中相关看似“对立”的概念，传统药方与现代方法、传统中药与西方医学、男性与女性、植物与动物等等，无不彰显出一个永恒规律：人类发展高度依赖且享有共同价值，因此帮助学生认识树立人类命运共同体意识重要且必要。】
Step 6 Summary: consolidating the three aspects discussed about in this passage.
T informs students of the event organized by BBC which was to choose “the greatest persons in 20th century” and Tu Youyou is included in this list and presents the prize announcement to further understand this great female scientist.
【设计意图：伟大人物之所以伟大，是因为他所具备的特点使他能为更广泛意义的社会需要服务。如果用衡量拯救多少人的生命来衡量一个人的伟大，那屠呦呦无疑是历史上最伟大的科学家之一。借用BBC评选20世纪最伟大人物时对屠呦呦的评价，回望文章内容的三个角度，总结全文的同时进一步感知人物形象。】
Step 6 Homework: reflecting on students’ dreams and inspiring them to pursue their dream guided by great people
Write a short passage about your dream and how you will pursue it.
What qualities do you need to possess
What if you fail during it
What contributions will you make to yourselves, to our country, or even to our world
【设计意图：由瞻仰伟大人物回归“平凡”的自我，其实看似平凡的每一步都在朝着自我的目标努力。伟大人物犹如灯塔，使我们的每一步都前行得更有底气，更加坚定。由屠呦呦的品质、面对挫折的态度以及最终成就相信也能对学生们有所启迪和思考，所以不妨借助写作的手段，在文字中认真思考，畅所欲言。】
