資源簡介

Unit 2 Saving the Earth Topic 3 Section A（教學設計）
Ⅰ. Material analysis
本課主活動是1a和2。1a 通過記者采訪Jane，詢問有關Jane 在環保組織的活動，引出話題內容：如何做一個環保人士。通過介紹在生活中如何踐行環保行為，自然地用到本話題的功能意念：提出建議。在提出建議的同時，又引出本話題的語法：并列句。1b是個難度比較高的聽力任務。它不是單純地考查聽寫，而是要求學生在聽懂內容的基礎上，對材料進行歸納之后再填空。1c是用第一人稱來轉述1a的內容，旨在向學生傳播環保理念。2是針對并列句而設計的專項語法訓練。3a和3b是在考查學生的垃圾分類意識之后，再通過聽對話來進行驗證。4再次讓學生對垃圾進行分類，以此來培養學生對垃圾再利用的環保理念。通過學習本課，可以增強學生的環保意識。培養學生在寫作時運用連接詞寫出比較連貫的句子的能力。

Ⅵ. Teaching procedures
Stage(time period) Interactionpatterns Teacher activity Student activity Remarks
1 Getting studentsready for learning（4 mins) Class activity Present a picture of heavy haze in Beijing and analyze the cause of it, learning some of the new words.T: Hi, class. Look at this picture. It’s Beijing. What’s the weather like there T: It’s neither cloudy nor foggy. It’s hazy. The word“haze”was the most frequently mentioned word in 2013 in the media in China. Especially in the big cities in northern China. How do you think the haze comes into being T: What you said sounds reasonable. Air pollution plays an important part. Luckily, the government is taking measures to solve this serious problem, and many organizations are taking part in the environmental protection, too. Jane is working for such an organization. Present a picture of heavy haze in Beijing and analyse the cause of it, learning some of the new words.S1: It’s cloudy.S2: It’s foggy.S3: I think air pollution causes haze.S4: I think too many cars.S5: I think too many factories. 學生沒有學過hazy (有霾的)，haze(霾)，老師要用漢語標注一下。學生弄懂以后才能展開后面的活動。老師在點評時可以講解：protection, organization. 最好用構詞法來呈現：protect(v)+tion=protection(n)organize（v,組織)+tion=organization (n)。
2 Lead-in（4 mins) Class activity Present some real objects to learn more new words and lead to 1a.T: Perhaps some of you think it’s difficult for students to do something to protect the environment. In fact, if you keep doing three R’s in your daily life, you will be a greener person. Could you guess what the three R’s refer to T: Sorry, guess again.T: Sorry, guess again.T: Smart boy! You have got one.T: Wonderful! You have got another. What’s the third one T: Now, let me tell you. It’s “recycle”. （Show the logo of recycling） Do you often see this sign on the boxes or bottles T: Three R’s are very important in our life. For example, we should reuse plastic bags and recycle batteries and drink cans. Present some real objects to learn more new words and lead to 1a.S1:Refuse S2:RememberS3: Reuse.S4: Reduce.S5:..Ss: Yes. 老師在提到Three R’s 時，應馬上板書出來，并讓學生猜是哪三個單詞，借此講解“re(再)+cycle（圓，環）=recycle (v). 老師在講解該詞時可以出示循環使用的標志以幫助理解新詞。老師在展示實物時，應馬上板書并講解新詞。如：plastic, battery, can.
3 Pre-listening (2 mins) Individual work Let the Ss read the table in 1b to get to know what they should pay attention to while listening. T: Now, please read the table in 1b. This time, the listening task is a little difficult. Only when you understand the dialog, can you complete the table. So while listening, you had better pay attention to the main content of the dialog. Read the table in 1b to get to know what they should pay attention to while listening. 1b的聽寫填空需要學生在完全理解對話的基礎上完成，老師要提醒學生專注于聽內容并要求學生在聽前閱讀1b,預測聽力內容。
4 While-listening (5 mins) Individual work Let the Ss listen to 1a and finish 1b. Then check the answers.T: Now, a journalist is interviewing Jane. Let’s listen to what they are talking about. After listening, complete the table. When you finish, put up your hand. T: Who would like to answer the question Listen to 1a and finish 1b. Check the answers.S1: Organization, protect the environment. S2: spread the message S3: … 1b的聽力任務難度有點大，可以讓學生聽兩遍。
5 Post-listening (10 mins) Individual workClass activityClass activity Step 1: Let the Ss read 1a and do 1c. Then check the answers.T: We have listened to the interview, and now let’s read it. Please complete the sentences in 1c while reading. If you finish, please let me know. T: Shall we start checking the answers now T: xxx, shall we start from you Step2: Let the Ss read 1a again to find the sentences which give suggestions.T: Have you found that in this dialog many sentences contain suggestions T: Have you found such sentences, xxx T: We usually use “should” to give suggestions. Who can give us an example Step 3: Deal with language points in 1a.T: Mmm, good examples. I hope you will act as you said. Any questions Hands up!T: xxx, please. T: Good question. We know the first “that” is an object clause, and the second one is a new kind of grammar. We will learn it in Unit4. It’s called“attributive clause”. Change it into“and it”, you will understand the sentence better. Who can put this sentence into Chinese T: Perfect! Any more questions T: Sure. “Sort” here is a verb. It means“divide according to different kinds”.“Can be recycled”is also a kind of grammar. It’s called passive voice. Because the waste can’t recycle by itself. It’s people who recycle it. In Chinese, the whole sentence is“然后，我們把它們進行分類以便它們能被回收再利用。” Read 1a and finish 1c. Ss: Sure.S1: Reduce, reuse ,recycleS2: Sides, plasticS3: …Read 1a again to find the sentences which give suggestions. Ss: Yes.S1: We should reduce the waste we produce. S2: We should use both sides of paper and reuse plastic bags.S3: …S4: We should listen to the teacher carefully in class. S5: We should keep the classroom clean.S6: We shouldn’t waste water.Step 3: Read 1a again and ask questions about some difficult points.S1: How to understand the second “that” in “We all know that you… that environment” S2:我們都知道你在一個保護環境的組織里工作。S3: Could you explain “Then we sort them so that they can be recycled” 對于本課出現的定語從句和情態動詞的被動語態，老師只要讓學生理解句子意思即可，不要求深度解釋。為了讓學生便于理解，老師可以簡單地用“把”字句和“被”字句來解釋被動語態。
6 FinishingTask 2(13 mins) Class activity Class activityIndividual work Step 1: Present the following sentences on the small Bb or on the screen. Let the Ss understand the underlined words to learn conjunctions. Sentences:So what can we do at home to protect the environment Recycling can protect the environment, and it can save money, too. So we encourage students to collect waste paper andsoft drink cans.T: Please look at the sentences on the Bb and understand the underlined parts. What do we call the underlined words T: Who can tell me some more conjunctions T: Besides these, I can name more conjunctions, such as: for, as, since, etc. And we usually use conjunctions to make compound sentences. For example: Hurry up, or you will be late for school. Zhang Hong likes apples, but I don’t like apples at all.Huang Rong is good at math while her twin sister is good at English.This coat looks nice and it’s cheap, too.Step2: Let one student come to the front to perform to learn the new words.T: Look! There are some sentences in 2. Now, read them quickly and circle the new words. If you finish, put up your hand.T: xxx, please come here.T: Only use your head, if you want to mean “yes”, what will you do T: Right. Nodding the head means agreement. Now, how to express“no”？T:Yes. Shaking the head means“disagreement”.T: Good performance. Please go back to your seat.T: Can you guess the meaning of the phrase“give up”in Number 5 T: Yes. I hope you will never give up when you are in trouble. Step3: Let the Ss combine the sentences with the given words in 2. Check the answers.T: Now, combine the sentences with the given conjunctions quickly. When you finish, please put up your hand.T: Now, it’s time to check the answers. Any volunteers Understand the underlined words to learn the conjunctions. S1:連接詞。S2: but, or S3: while ,because Learn the new words through actions.S1: (nod his head)S1: (shake his head)S2:放棄Combine the sentences with the given words in 2. Check the answers. S1: Noise is a kind of pollution and it’s harmful to our hearing.S2: Work hard, or you will fail the exam.S3: … 并列句是本課的學習重點。老師如果覺得用英語講解學生難以弄明白，不妨就用漢語表述。但是“compound sentence, conjunction”這些術語要學生能聽懂才行，學生以后會經常聽到。老師最好將所舉的例子板書出來，以加深印象。老師可以自己（最好讓學生）做動作同時輔以構詞法來講解: agree (v) + ment =agreement(n) dis(不)+agree（v）+ment=disagreement(n)。
