Unit 4 Amazing Science Topic 3Section B（教學設計）
Ⅰ. Material analysis
本課主活動是1a。1a通過Kangkang向Mr. Brown了解宇宙飛船的相關知識，把話題的內容由宇宙飛船引入到電腦科技并繼續學習定語從句。1b主要是培養學生運用已知的知識來推斷未知的知識的能力。1c則是通過完成短文來復述1a的內容。2是訓練“聽并排序”和“聽并記錄”的技能，在訓練技能的同時拓展了學生的知識面。3是典型的語法操練，鞏固定語從句關系代詞的運用。4將語音語調的訓練與定語從句結合了起來。

1 Revision（3mins) Individual work Let the Ss read out their sentences with attributive clause.T: Hi, boys and girls! Let’s begin our class. Do you still remember the grammar we learned in the last period T: Have you written five sentences with attributive clause T: Who wants to show us Don’t be afraid of making mistakes.T: That’s terrific! You all made up so nice sentences. Read out their sentences with attributive clause.Ss:定語從句。Ss: Yes.S1: Look at this photo. The boy who/that is next to me is my cousin. S2: Oh, my god! The book which/that I borrowed from the school library is lost.S3: The man who has two children will be our new P.E teacher.S4:… 可能有的學生寫的句子會出現從句的謂語與主句的人稱不一致的錯誤，老師要加以改正。另外，目前所學的定語從句里，關系代詞在從句中都是作主語。老師也可以有意識地提一下：關系代詞還可以做其他成分。
2 Pre-listening(7mins) Group workIndividual work Step 1: Let the Ss discuss how the spaceships work during the flight to lead to 1a.T: We know spaceships play an important part in exploring the outer space. Do you know how the spaceships work during the flight Discuss in groups for a while, and then report to the class.T: Do you have any ideas, Group 1 T: Group 2 T: Good ideas! Which group is right Let’s keep it as a secret. After listening to 1a, you will get the answer.Step 2: Let the Ss read the statements in 1b, tick the possibilities.T: Maybe you know much about computers. Try to predict what computers can do to spaceships. Tick what you think may happen. Discuss how the spaceships work during the flight.S1: We think the spaceships are controlled by the astronauts.S2: We don’t agree. We think the spaceships are controlled by computers.S3: …Read the statements in 1b and tick the possibilities. 如果學生不能用英語來討論飛船是怎樣工作的，也可以用漢語來表達。讓學生根據已有經驗來預測未知的領域有助于激發他們聽的欲望，并更專注于特定的內容。
3 While-listening(4mins) Individual work Let the Ss listen to 1a and get the answers to discussion and prediction. Check the answers. Finish 1b.T: Now, you may be eager to know which group is right and whether you predicted correctly. Now, it’s time to find out the answers. Listen to 1a carefully and check the answers. When you finish, put up your hand.T: Which group is right, do you know T: Maybe it’s hard to tell which group is right up to now. Don’t worry. You will know the answer later. But I’d like to know who predicted most correctly. xxx, have you got them correctly T: Do you agree with him, everyone Listen to 1a and get the answers to discussion and prediction. Check the answers. Finish 1b. S1: Group 1.S2: Group 2.S3: Group 3.S4: ….S5: Yes. No.2, No.3 and No.4.Ss: Yes. 因為學生還沒有學習“electronic”，所以難以得到正確的答案，可以等到他們閱讀1a后再揭曉。
4 Post-listening(12mins) Class activityClass activity Step 1: Let the Ss read 1a, find the new word and the attributive clause and do 1c at the same time.T: We have listened to 1a and now let’s read the dialog. When reading, you should find the new word, the attributive clause and do 1c. If you finish, raise your hand.T: There is only one attributive clause in the dialog. Have you found it, xxx T: Electronic.T: Follow me, everyone. “Electronic”.T: (show an electronic watch) Look! This is a watch. It’s an electronic watch. Can you guess what “electronic” means T: Right! Now, do you know how spaceships work during flight T: Absolutely right.T: Then let’s check the answers to 1c. One student for one blank. xxx, begin with the first blank, please. T:Very good! Pay attention to the phrase“make up one’s mind to do sth.”.Step 2: Let the Ss read 1a again and find out the difficult points and useful expressions.T: Now, you have got all the answers. Next, we will pay attention to difficult points and expressions. Read 1a again and try to find out the difficult points and useful expressions. When you finish, put up your hand.T: Any difficult points T: You know “used to do sth.”, right T: It’s the passive voice of it. Its structure is “V+to+be +pp”. For example, “The classroom is too dirty. It has to be cleaned right now.”T: No more questions Then how about expressions Read 1a, find the new word and the attributive clause and do 1c at thesame time.S1: Yes. Spaceships which now mainly use …electronic controls used to be controlled by astronauts.Ss: Electronic.S2:電子的。S3: They were controlled by astronauts in the past, but now they are controlled by computers.S4: controlledS5: electronicS6: …Read 1a again and find out the difficult points and useful expressions.S1: What does “used to be controlled” mean S1: Yes.S2: advise sb.to do sth.S3: Thanks for your introduction. 學生在找到定語從句后，可能不會讀“electronic”,這時老師要及時板書并領讀。對于學生可能提出的動詞不定式的被動語態，老師不要多講，只要讓學生知道有這種用法，知道意思就行了。
5 FinishingTask 2(7mins) Class activityIndividual workIndividual work Step 1: Let the Ss look at the pictures to learn the new words and get to know the listening materials.T: Hey！Look! There are some pictures in 2. Some of them look strange. What is Picture 2 Can you guess it T: Yes. They are clothes. They are for astronauts. They are called spacesuit. Repeat，“ spacesuit”.T: Have you seen the things in Picture3 T: I haven’t seen them, either. I give you some hints. “Tele-” means “faraway”, “-scope” means “something like a mirror”. Can you guess it now T: Smart boy! Look , I have a telescope here.T: Now, you will listen to four short passages and try to number the pictures.Step 2: Let the Ss listen to 2 and number the pictures.T: Tell me the order, boys and girls!T: Right Step 3: Let the Ss read the sentences in B quickly and get to know what they should pay attention to. Then, listen to 2.T: Task A is quite easy, but Task B is a little difficult. You’d better read the sentences quickly and get to know what you should pay attention to. And you should write as quickly as possible while writing, just as we did before.T: Shall we check now T: One student for one sentence. xxx, you begin with the first one. Look at the pictures to learn the new words and get to know the listening materials.S1: 宇航員。S2: 不對，看起來像衣服。Ss: spacesuit.Ss: No.S3: 望遠鏡。Listen to 2 and number the pictures.S1: 2-1-3-4.Ss: Yes.Read the sentences in B quickly and get to know what they should pay attention to.Then, listen to 2.Ss: OK.S1: spaceshipS2: water, dried foodS3:.. 可以通過構詞法來教學：space+suit(一套衣服)=spacesuit，tele(遠的) + scope (鏡，儀器) =telescope。這種聽寫型的任務，應讓學生先看題，以便明確目標。如果學生一次不能完成，可以聽兩次。
6 FinishingTask 3(3mins) Individual work Let the Ss do 3, check the answers and finish 3.T: We have learned attributive clause. Now, it’s time to check whether you can use it correctly or not. Please do 3 alone. When you finish, put up your hand.T: xxx, No.1, please.T: I’m glad that you have improved a lot. Do 3, check the answers and finish 3.S1: who/thatS2: which/thatS3: which/thatS4: …

Pay attention to the pause, weak form and intonation.Step 3: Encourage some students to imitate the tape.

Which words can be used as relative pronouns T: How to choose relative pronouns T: How to decide the forms of the verbs in the clause Step 2: HMKT: Look at the example on the Bb.

Sum up this section.S1: Who.S2: Which.S3: That.S4: 先行詞指人時，用who/that；先行詞指物時，用which/that。S5: 與先行詞保持一致。先行詞是單數，動詞用單三式；先行詞是復數，動詞用原形。
