Unit 7 Great scientists 单元解读

一、新课标理念体现

本单元话题为伟大科学家，围绕制作科学家幻灯片展开，属于“人与社会”主题范畴，“文学、艺术与体育”主题群，涉及“常见职业”子主题。单元以Big task（Making a slide show of a great scientist）为驱动，引导学生在认识科学家品质词汇、诵读科学颂诗、谈论中外科学家的贡献与故事、阅读袁隆平和贝尔的传记语篇的完整过程中学会用英语介绍科学家的国籍、成就与品质，体现了新课标“在体验中学习、在实践中运用、在迁移中创新”的理念，强调语言学习与科学素养和文化自信的深度融合。

二、课时划分

第1课时：Topic words & Rhyme time & Talking time（教材第57–61页）

第2课时：Reading time & Project（教材第62–64页）

三、单元内容分析

本单元以“伟大科学家”为主题，由开篇页、第1课时（视听说课）和第2课时（阅读与项目实践课）构成，板块之间呈现从科学家品质词汇输入到科学颂诗诵读再到科学家介绍对话，以及从科学家传记阅读到科学家幻灯片制作的递进逻辑。

第1课时为视听说课，以科学家及其成就为线索，呈现场景词汇和This is ..., a/the ...同位语结构。Topic words板块呈现七个词汇（scientist科学家、explore探索、famous著名的、discover发现、be known as被称为、hard-working勤奋的、creative有创造力的），涵盖一个职业名词、两个行为动词、一个形容词、一个被动结构和一个复合形容词，配图呈现四位科学家（袁隆平、爱因斯坦、贝尔、屠呦呦），A部分Listen and complete the notes活动训练学生听取“With science”引导的语段并完成笔记——With science, we can go to space / the deep sea / every corner of the world; we can have video calls with grandparents / get information fast / learn more with less time or money——将科学词汇与科学改变生活的实例关联，承担词汇输入功能；Rhyme time板块以Science为题呈现科学颂诗——Science opens a window for humans.（科学为人类打开一扇窗）/ With science, we can go farther. / With science, we can fly higher.（有了科学，我们能走得更远、飞得更高）/ With science, we find out Why apples fall to the ground.（有了科学，我们弄清了苹果为何落地）/ With science, we now know Why the earth goes around the

sun.（有了科学，我们现在知道地球为何绕太阳运转）/ Science helps us understand the world around us.（科学帮助我们理解周围的世界）/ Science helps us explore outer space.（科学帮助我们探索外太空）/ Science is cool. It’s really cool to be a scientist!（科学很酷，当科学家真酷！）——诗歌从科学的功能（go farther / fly higher）到科学的发现（apples fall / earth goes around the sun）再到科学的意义（understand the world / explore outer space）层层递进，Sound板块聚焦辅音字母组合fl和pl的发音（fly / explore / flap / plane），呈现韵律诗“The birds flap wings and fly so high. A plane can be like a bird and fly in the sky.”，B部分Ask and answer活动引导学生用What can you do with science? / With science, I can ...谈论科学能为自己做什么，在口语中将诗歌的宏大叙事个人化；Talking time板块以“你认识他们吗”为情境呈现This is ..., a/the ...同位语结构的核心对话——场景1中Shenshen看著名科学家照片（Look at these photos of famous scientists.），Xiaopu识别屠呦呦（Oh, this is Tu Youyou, a Nobel Prize winner.），Minmin询问了解什么（What do you know about her?），Shenshen介绍她发现青蒿素挽救了许多生命（She discovered qinghaosu and has saved many lives.），Xiaopu赞叹（Wow. She is great!）；场景2中Minmin指认牛顿（Look here! It’s Newton.），Shenshen问苹果的故事（Do you know the story of “Newton’s apple”?），Minmin讲述——年轻的牛顿在苹果树下思考宇宙，苹果突然落在头上，他深思苹果下落的原因，后来发现了万有引力定律（Young Newton was thinking about the universe under an apple tree. Suddenly an apple fell on his head. He thought hard about the reasons for the fall of apples. And later he discovered the Law of Gravity.），Xiaopu指认钱学森（Look, Qian Xuesen, a rocket scientist. I’m a big fan of him.），Shenshen表达志向（I’m also interested in outer space. I want to be a scientist like him in the future.），Minmin鼓励（Your dream will come true.），B部分Read and complete the notes活动引导学生完成三位科学家的信息表（Name / Nationality / Known for），C部分Tell your partner about your favourite scientist活动引导学生用... is my favourite scientist. He/She is/was ... He/She ...介绍自己最喜爱的科学家，Find the rule板块提炼This is Tu Youyou, a Nobel Prize winner. / This is Qian Xuesen, a rocket scientist. / This is Yuan Longping, the “Father of Hybrid Rice”.三个同位语例句，帮助学生掌握“This is人名, a/the身份”的介绍结构。

第2课时为阅读与项目实践课。Reading time板块以Great scientists为题，呈现两位科学家的传记语篇——袁隆平篇：Yuan Longping was born in Beijing in 1930. In the 1960s, as the nation was short of food, Mr Yuan began to do research on hybrid rice. He was creative and hard-

working. His hybrid rice has fed many people. Mr Yuan is known as the “Father of Hybrid Rice”.——袁隆平1930年生于北京，六十年代国家缺粮时开始研究杂交水稻，他富有创造力且勤奋，杂交水稻养活了很多人，被称为“杂交水稻之父”；贝尔篇：Alexander Graham Bell was born in Scotland in 1847. He was always curious about new things. He and his assistant Thomas Watson invented the world’s first practical telephone. Bell was interested in many research areas. He invented a lot of techniques to help the deaf.——贝尔1847年生于苏格兰，总是对新事物好奇，与助手沃森发明了世界第一台实用电话，对多个研究领域感兴趣，发明了许多帮助聋人的技术，Quick tip板块区分interest（名词兴趣/动词使感兴趣）、interesting（形容词有趣的）、interested（形容词感兴趣的）三个词的词形与用法，A部分Read and complete the fact files活动引导学生完成两位科学家的档案卡（Name / Famous for），B部分Choose and speak活动引导学生从brave / creative / curious / hard-working / caring / clever六个品质中选择科学家最重要的品质并说明理由（A scientist is usually ...），发展品质评价与论证思维；Project板块以A slide show of a great scientist为任务，A部分View and learn提供顾方舟的幻灯片范例——“Grandpa of sugar pill”（糖丸爷爷）Gu Fangzhou is a great scientist. He is known as the “Grandpa of sugar pill”. He created an oral vaccine against polio. It has saved many children in China.——顾方舟创造了脊髓灰质炎口服疫苗，拯救了中国许多儿童，B部分Make a slide show分四步完成（Step 1 Do research work: Name / Nationality / Known for → Step 2 Search and insert: Insert the pictures or media you want to use → Step 3 Search and add: Add text, music, or transition effects to your slides → Step 4 Preview and save your slide show），C部分Show and tell引导学生用... is a great scientist. He/She was born ... / He/She was/is interested in ... / He/She ...展示并讲述自己的幻灯片，实现从阅读科学家传记到制作科学家幻灯片的完整产出。
