3． 情感態(tài)度與文化意識
（1).進一步培養(yǎng)小組合作學習的能力，通過調查、采訪、討論等活動完成任務，取長補短，加強團體協(xié)作意識。
（2).引導學生用英語進行不同學科特點的思考，體會學科之間的聯(lián)系與區(qū)別。通過話題啟發(fā)學生積極思考，調動學生的學習興趣。
（3).指導學生用批判的思維去接受新的事物，增強他們的辯論意識與能力。
（4).意識到科技工作的艱苦以及所必需的個人品質與素質，鼓勵學生在學習過程中的創(chuàng)新精神與實踐能力。
4． 學習策略
指導學生運用已學會的抓重點、做記號、摘筆記等方式對所學內容進行整理與歸納，并鼓勵學生增加與教師和同學交流、合作，繼續(xù)培養(yǎng)正確的自我評價與相互評價的習慣，從而總結交流學習所得，進一步形成有效的學習方法。并指導學生把英語學習從課堂延伸到課外，發(fā)揮已掌握的使用工具書，查找資料、上網(wǎng)等方式增加用英語思維與表達的能力，了解實驗對于科學研究的重要性，樹立正確的向上的學習態(tài)度，形成具有批判性的看問題習慣。
三. 教學內容分析
本單元的中心話題是science and scientists。話題依附于聽力、對話、閱讀與寫作等語言載體中。本單元的話題內容與學生的日常學習有著密切的關系，應該說是以英語為媒體讓學生表達他們對平時理化生等理科課程，特別是相關實驗，所想到及感受到的內容。因此，盡管本單元的話題對學生而言有著一定的難度，但卻有體現(xiàn)出了以學生為中心，貼近學生生活而又富有時代氣息的特點。
Warming up設計了四幅與學生的理科課程有關的圖片，學生通過對日常熟悉的相干實驗工具及場地的識別，展開相關學科特點與學習的討論。同時在此基礎上，要求學生們在Listening部分能熟悉某些實驗室的規(guī)則及注意事項，掌握如何給予別人指導與說明，并能抓住文章的中心話題，捕捉相關細節(jié)內容，回答有關的問題。
Speaking則是一個極富時代氣息的討論練習。要求學生們能對現(xiàn)在熱門的尖端科技有所了解，（練習中提供了諸如Maglev train, cloning, nuclear energy, computer 與 space flight等內容）然后能就這些新的科學技術與工具進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，同時也能發(fā)現(xiàn)其中所存在的不足與弊端，并能通過討論、對話等形式發(fā)表自己的觀點與想法。這一部分也應該是本單元寫作內容的一個鋪墊。
Reading講述的是科學家Franklin著名的風箏實驗，從而證明Lighting and electricity are the same的故事。學生在理解文章的基礎上，能充分感受到實驗對于科學工作的重要性及科學家是如何獲得事業(yè)上的成功的。同時能落實材料中所出現(xiàn)的一些單詞與短語的使用。
Language Study是在本單元詞匯學習的基礎上，讓學生進一步了解并掌握一定的構詞法。主要是兼類詞、一詞多義現(xiàn)象及合成詞的構成。
Integrating skills 通過學生對科學家是否應利用動物進行實驗，從而達到發(fā)明新產品現(xiàn)象的討論，理性的從正反兩個方面看待這一問題。同時在閱讀、思考與討論的基礎上，寫下一篇闡明自己觀點、立場與看法的短文。

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).
Emilio: 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.
Emilio: 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 do:
(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?
A.What college did Wong- Staal attend
B. What type of biology did she specialize in
C.Where 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 Procedures
Step 1 Warming up
Daily 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? Or does he doctor the doctor the way the doctor who doctors doctors?
Practise the tongue twister for some times and see who can say it correctly and fast.
Q: Do all “doctors” in this sentence have the same meaning?
Conclusion: The meaning of the same word varies in different sentences and so does the gender.
Step 2 Reading and thinking
1). Pair work
Read the following sentences to distinguish the different meanings of the same word.
How much do you charge for repairing my CD player?
The frightened animal charged into the toy shop.
It usually takes one hour to get my call phone fully charged.
The man was charged for being irresponsible for the job in the court.
We gave her the charge of the house when we were away for holiday.

He was surprise to see so many crosses marked in his Maths homework.
This fruit is a cross between an apple an d appear.
The river was too deep to cross.
The two main roads cross in the center of the town.
He crossed his name off the list.
2). Group work
Discuss in groups to think about more words of this kind and make sentences according to the different meanings. Then read it out and the other students try to guess the meaning of the same word in different situations.
Step 3 Imagination
Group work
Show some words on the screen ( such as bank, tie, sharp, tear) . Discuss in groups to make a short story, paying great attention to the different meanings and gender of the same word. Write it down on a card and share it with the whole class. See which group does the best job.
Step 4 Compound words
Sometimes if we put two different words together, we can make a new one. These words are called “Compound words”. Show some examples:
Blackboard is compounded with two words:
Part 1= a kind of deep color Part 2= a piece of thin wood
Show the students the formulation: Part 1 + Part 2 = ?
1). Class work
The teacher provide explanations to two single words. Ask the students to combine them together and then guess what the new word is. Repeat it for several groups.
Part 1= part of the body used when we talk Part 2= a round thing to play with
Part 1= water of ten degrees below zero Part 2= medicine to put on your skinPart 1= a liquid you need to make tea
Part 2= moving in snow with wooden thing tied to your shoes
2). Group work
Discuss to think of some some compound words in groups and then do the same game with the partners.
3) Class work
Have a competition about word guessing and see which team can give the most wonderful performance.
Two students to make a team with one facing the blackboard and the other facing all the students. The teacher lists some compound
words on the screen. The students facing the Bb explains the two parts of the compound word as quickly and exactly as possible, so
that the other one can join the two parts together to guess which word is mentioned. The game is limited in two minutes and then they
can find out which team have guessed more words than the others.
Step 5 Post-learning
Read the story about “Franklin’s famous kite experiment” again , and try to find out all the similar words as those learned in this class.
Homework:
Task 1. Design an exercise to match the words in Column A with those in Column B to make some compound words. Exchange the exercises in class.
Task 2. Prepare to make up a story about the relationship of humans and animals in groups and then act the short play out.
