Unit 16 Scientists at work 一. 教學(xué)背景分析
1．學(xué)生情況分析
本單元的設(shè)計(jì)與實(shí)施是建立在學(xué)生經(jīng)過高一上半學(xué)期新教材學(xué)習(xí)基礎(chǔ)之上。學(xué)生已經(jīng)逐步的適應(yīng)了在活動(dòng)與任務(wù)中學(xué)習(xí)英語(yǔ)以及如何處理語(yǔ)言知識(shí)與活動(dòng)開展的關(guān)系。并且，他們也已經(jīng)形成并培養(yǎng)了一定的小組合作學(xué)習(xí)及自主學(xué)習(xí)的能力。
2. 單元背景分析
隨著科學(xué)技術(shù)的發(fā)展，各種各樣新的發(fā)明和發(fā)現(xiàn)都層出不窮。生活在這樣一個(gè)知識(shí)爆炸的年代，學(xué)生們更應(yīng)用心去體會(huì)并感受科技和發(fā)明創(chuàng)造者給生活帶來的變化，進(jìn)而能聯(lián)想到他們平時(shí)所學(xué)的學(xué)科及知識(shí)，并用英語(yǔ)為媒介進(jìn)行知識(shí)的整合與串聯(lián)。同時(shí)從另一個(gè)角度來說，科技進(jìn)步的同時(shí)，我們的社會(huì)也產(chǎn)生了各種各樣的矛盾與爭(zhēng)論，因此如何正確的看待或處理這些問題，也成為廣大學(xué)生應(yīng)該了解并掌握的知識(shí)。

三. 教學(xué)內(nèi)容分析
本單元的中心話題是science and scientists。話題依附于聽力、對(duì)話、閱讀與寫作等語(yǔ)言載體中。本單元的話題內(nèi)容與學(xué)生的日常學(xué)習(xí)有著密切的關(guān)系，應(yīng)該說是以英語(yǔ)為媒體讓學(xué)生表達(dá)他們對(duì)平時(shí)理化生等理科課程，特別是相關(guān)實(shí)驗(yàn)，所想到及感受到的內(nèi)容。因此，盡管本單元的話題對(duì)學(xué)生而言有著一定的難度，但卻有體現(xiàn)出了以學(xué)生為中心，貼近學(xué)生生活而又富有時(shí)代氣息的特點(diǎn)。
Warming up設(shè)計(jì)了四幅與學(xué)生的理科課程有關(guān)的圖片，學(xué)生通過對(duì)日常熟悉的相干實(shí)驗(yàn)工具及場(chǎng)地的識(shí)別，展開相關(guān)學(xué)科特點(diǎn)與學(xué)習(xí)的討論。同時(shí)在此基礎(chǔ)上，要求學(xué)生們?cè)贚istening部分能熟悉某些實(shí)驗(yàn)室的規(guī)則及注意事項(xiàng)，掌握如何給予別人指導(dǎo)與說明，并能抓住文章的中心話題，捕捉相關(guān)細(xì)節(jié)內(nèi)容，回答有關(guān)的問題。
Speaking則是一個(gè)極富時(shí)代氣息的討論練習(xí)。要求學(xué)生們能對(duì)現(xiàn)在熱門的尖端科技有所了解，（練習(xí)中提供了諸如Maglev train, cloning, nuclear energy, computer 與 space flight等內(nèi)容）然后能就這些新的科學(xué)技術(shù)與工具進(jìn)行理性的辨證的思考，既能感受到它們給我們的生活帶來的巨大利益，同時(shí)也能發(fā)現(xiàn)其中所存在的不足與弊端，并能通過討論、對(duì)話等形式發(fā)表自己的觀點(diǎn)與想法。這一部分也應(yīng)該是本單元寫作內(nèi)容的一個(gè)鋪墊。
Reading講述的是科學(xué)家Franklin著名的風(fēng)箏實(shí)驗(yàn)，從而證明Lighting and electricity are the same的故事。學(xué)生在理解文章的基礎(chǔ)上，能充分感受到實(shí)驗(yàn)對(duì)于科學(xué)工作的重要性及科學(xué)家是如何獲得事業(yè)上的成功的。同時(shí)能落實(shí)材料中所出現(xiàn)的一些單詞與短語(yǔ)的使用。
Language Study是在本單元詞匯學(xué)習(xí)的基礎(chǔ)上，讓學(xué)生進(jìn)一步了解并掌握一定的構(gòu)詞法。主要是兼類詞、一詞多義現(xiàn)象及合成詞的構(gòu)成。
Integrating skills 通過學(xué)生對(duì)科學(xué)家是否應(yīng)利用動(dòng)物進(jìn)行實(shí)驗(yàn)，從而達(dá)到發(fā)明新產(chǎn)品現(xiàn)象的討論，理性的從正反兩個(gè)方面看待這一問題。同時(shí)在閱讀、思考與討論的基礎(chǔ)上，寫下一篇闡明自己觀點(diǎn)、立場(chǎng)與看法的短文。

五、教學(xué)原則
（1）以任務(wù)型教學(xué) (Task-based Language Teaching)作為課堂教學(xué)設(shè)計(jì)之理念，具體采用情景教學(xué)法（Situational Approach），交際教學(xué)法（Communicative Approach），整體語(yǔ)言教學(xué)法（Whole Language Teaching）等教學(xué)方法。從一定程度上說，人們使用語(yǔ)言是為了完成各種各樣的任務(wù)，而任務(wù)型的教學(xué)活動(dòng)就是讓學(xué)習(xí)者通過運(yùn)用所學(xué)語(yǔ)言來完成各種各樣的交際活動(dòng)。學(xué)習(xí)者通過表達(dá)、溝通、交涉、解釋、詢問等各種語(yǔ)言形式來學(xué)習(xí)和掌握語(yǔ)言，實(shí)現(xiàn)目標(biāo)，感受成功。
（2）在教學(xué)中突出交際性，注重讀寫的實(shí)用性；同時(shí)適時(shí)進(jìn)行情感與策略調(diào)整，以形成積極的學(xué)習(xí)態(tài)度，促進(jìn)語(yǔ)言實(shí)際運(yùn)用能力的提高。
（3）堅(jiān)持“教師為主導(dǎo)，學(xué)生為主體，任務(wù)為基礎(chǔ)”的教學(xué)原則，在課堂教學(xué)的不同環(huán)節(jié)教師應(yīng)扮演自身作為“設(shè)計(jì)者，研究者，組織者，促進(jìn)者，協(xié)調(diào)者”的角色。
（4）貫徹“教中學(xué)，學(xué)中用”策略，真正使學(xué)生學(xué)以致用。

Q1: How many subjects are you learning now? Q2: What are the subjects in which you learn science? Is it easy for you to learn them? 1). Group work Divide the whole class into two groups, one group is going to talk about the question “ What do you learn about for each field of science?”, and the other “How are you learning these subjects?” Write down the result of the discussion in a card, and choose the best member to do the report. 2). Class work Enjoy some pictures about the facilities in labs and students doing experiments in labs. Q: Which subjects are connected with these pictures? Do you often do experiments in the lab?Step2 Pre-listening1).Group work Is it necessary for you to do experiments in the lab? List the reasons in the card and see which group can find more. 2).Class work Do you still remember what your teacher often remind you before, when and after you do an experiment? Divide the whole into several groups to have a competition in class and see which group will win the game.Step 3 Listening1). Listen to what Mr. Zhu is talking to his students for the first time, focusing on the subjects mentioned in the passage. 2). Listen to the tape for the second time to write down some key words to the questions and check with the partners. 3). Listen to the tape for the third time.

Period 3 & 4 ReadingLearning Aims
1. To get to know something about the story of famous scientists. 2. Enable students to understand the given material better using different reading skills. 3. To have a better understanding about the importance of experiments in science.Learning ProceduresStep 1 Warming upDaily report: Share your poems with the other students. 1). Group competition In the 18th and 19th century, scientists all over the world made many important discoveries and inventions in different fields of physics, chemistry, medicine, biology and so on. Divide the whole class into four groups to name some of them. Physics chemistry medicine biology
2). Group work A match competition. Match Column B with Column A correctly. Column A Column B Alexander Bell the Theory of Relativity Thomas Edison the first telephone Wright Brothers the electric lamp Madame Curie black holes in Universe Heinrich Dreser electricity Franklin the first plane Steven Hawking the Theory of Gravity Elbert Einstein Radium Isaac Newton aspirin 3) Class work Q1. Is it easy for the scientists to make these inventions and discoveries? Q2. How could they succeed in their research? It is really difficult for the scientists to achieve their goal , and only after tens of thousands of attempts, experiments, thinking and failure can they be successful in their research. Today, we are going to learn one example of them: Franklin’s famous kite experiment.Step 2 Reading1). Individual work Skimming: Read the material fast to find out the right picture about Franklin’s experiment. 2). Individual work Scanning: Listen to the tape part by part to find out the topic for each one. Para 1-3 the description of the experiment Para 4 the equipment of the experiment Para 5-6 the steps of the experiment Listen with the questions below: (1). Why did Franklin do this experiment? (2). Was the experiment successful? (3). What were needed when it was being done? (4). How many steps were mentioned? (5). What should be paid great attentions to when it was being done?Step 3 Acting1). Class work With all the equipment ready ( a handkerchief made of silk, two pieces of light wood, strings, a sharp piece of metal, a key, a silk ribbon ), one student acts as the host to conduct two students how to make a kite as the one made by Franklin. 2). Individual work After that, all the students try to tell how to make such a kite in their own words with the help of the pictures on the screen.Step4 Further understanding 1). Pair work Read through the passage to fill in the blanks in the form in pairs. equipment usage a kite
a key
a condenser
a sharp metal
strings
a silk ribbon
2). Class work Listen to some sentences to judge whether they are true or false. (1). In 1752 scientists already knew what electricity is. (2). Franklin was helped by a friend to do the experiment. (3). Franklin made the kite of silk because wet silk does not conduct electricity. (4). A condenser was used in the experiment to store electricity. (5). The key tied to the string was put into the door to stop the kite from flying away. (6). The experiment can be done at any time. (7). You can feel clear electric shock if you touch the string with your fingers after the kite is flying in the sky. Step 5 Post-reading 1). Pair work Franklin was doing the experiment with his little son, and he was a bit curious about what his father was doing. On the other hand, many people were watching Franklin doing the experiment. Divide the class into two groups to make a dialogue in pairs, one is between Franklin and his son ,the other Franklin and a person watching the experiment.
2). Group work Discuss the following questions in groups: (1). Why did Franklin do his experiment with a kite? (2). Why the kite made of silk is better than the one made of paper? (3). Is it dangerous for Franklin to do the experiment? Why do think so? (4). What can you learn from the experiment and also Franklin?Step 6 Oral practice1). Individual work After you read the interesting experiment of Franklin, do you think of one of your own experiments? Is it a very successful one? And what do you learn after you do the experiment? Tell the story to your group members, and then choose the best one to share it with the whole class. 2). Class work During the lifetime of many famous scientists, there are a lot of interesting and instructive stories for us to enjoy. Then, we are going to hold a story telling competition in class. Have some judges among the students first, and then each group choose one student to present the story in front of the classroom. See who can get the first prize in the competition.Step 7 Watching, reading and thinking1). Class work The teacher is ding such an experiment and showing it to all the students: Prepare four glasses on the table. One is filled with oil, one vinegar, and one spirit. Pour some of the liquid into one big glass and then mix them up. Dip one finger into the mixture, take it out then and put it into the mouth to suck. Then give a smile to the students to show that it tastes very delicious. Show the glass around the class and ask the students to do everything as the teacher does. Q: Does the mixture taste good? Why do you have a different taste from mine? 2). Individual work Read the passage titled “Look carefully and Learn” to find out the reason. Q 1: What do you learn after you read such a story? Q 2: Do you think what is the most important when you are doing an experiment in the lab?
Q 3: If you want to be a scientist, what do you think are the most important qualities?
Homework:
Read the following passage with the questions below.Flossie Wong-Staal
An interview with Emilio Alvarez and Ann Crystal Angeles
Flossie Wong-staal stays on the move. She moved with her family from China to Hong Kong when she was five. Later she moved to the United States to attend college. Now Wong-Staal is on the move to clone the virus that is believed to cause AIDS and to figure out how the molecules（分子）of the virus are arranged. Wang-Staal heads a team of scientists at the university of California, San Diego. They are trying to save lives by making an AIDS vaccine(疫苗). Emili How did you decide that you wanted to become scientist? Wong-Staal: At first my teachers made the decision. In high school they said I should study science because of my grades. By the time I graduated from college, there were so many exciting discoveries being made in molecular biology that I wanted to specialize it. Emili What was your high school like? Wong-Staal: I went to an all-girl high school in Hong Kong. I felt very free at an all-girl school, and I have fond memories of that time. Anne Crystal: Would you explain your research? Wong- Staal: Basically me colleagues and I are trying to understand how the AIDS virus is replicated, and then to develop ways to interrupt the replication process, By “replication” I mean the way in which the virus gets inside a cell and uses that cell as a sort of factory to make many many copies of itself. Anne Crystal: Do you always enjoy your job in the laboratory? Wong-Staal: Yes,, I think it’s very exciting work. Of course it’s not every day that you make a discovery and have that kind of reward. But when it does happen, it’s a real thrill. It’s exciting to know that you brought about knowledge that didn’t exist before. Anne Crystal: What would you tell students who would like to become research scientists? Wong- Staal: Stay with your interest, and get good information about the education you will need. I also have warning: Things are not always easy. There are frustrations in research; sometimes things don’t go the way you’d hoped. But when you make a discovery or a contribution to science, it becomes worthwhile. And I want to encourage all young people to be interested in science: We need you ! 1. As you read, guess the meaning of the boldface words from the surroundings words and sentences. 2. Look back over the reading to find the following information: (1). Where Wong-Staal was born: (2). What she is studying in her research: (3). What she was the first person to d (4). This article is primarily about______________. A. the scientist Wong- Staal B. making an AIDS vaccine C. preventing the spread of disease (5). Which question is NOT answered in the reading?What college did Wong- Staal attend B. What type of biology did she specialize inWhere does she work now(6). You can infer that Wong- Staal A. didn’t want to become a scientist B. is happy she becomes a research scientist C. plans to retire soon 3. Write about the following two questions in your journal. (1). Wong- Staal says that there are frustrations in research. What do you think she means? What frustrations might there be in doing research? How would you deal with these frustrations? (2). Wong- Staal says that here teachers decided she should become a scientist. Do you think teachers should make career choices for their students? Why or why not?
Period 5 Language study
Learning Aims
Enable students to have a better knowledge of the rules of word-formation.Learning ProceduresStep 1 Warming upDaily report: Show your opinions about the two problems mentioned in the reading passage. Individual work Show a tongue twister to students: If one doctor doctors another doctor, does the doctor who doctors the doctor doctor the doctor the way the doctor he is doctoring?
