Teaching procedures Stage(time period)InteractionpatternsTeacher activityStudent activityRemarks1Getting students ready for learning（3 mins)Class activityPlay a short video about a sandstorm and let Ss guess what kind of weather it is.T: Hi, boys and girls!

8、好準(zhǔn)備。教師在教讀單詞時，注意使用升調(diào)和降調(diào)，配上手勢，培養(yǎng)學(xué)生的語音語調(diào)。2Lead-in (3 mins)Group work Show the pictures of a sandstorm, let the Ss guess how sandstorm comes into being and number the pictures in 3.T: OK, do you know how sandstorm comes into being?

Look at the pictures about a sandstorm, guess how sandstorm comes into being and number the pictures in 3.S1: Its 4-1-5-3-6-2. 先處理3部分，簡單描述沙塵暴形成的過程，讓學(xué)生對這種天氣，有所了解，然后在進(jìn)入1a，詳細(xì)談?wù)撋硥m暴形成的原因以及樹木的功能，這樣，讓課堂環(huán)節(jié)更加流暢。3Pre-li

10、stening (5-7 mins)Group work Let the Ss talk about sandstorm according to the pictures and the given words in 3 in groups.T: Yeah, you are right. With the help of pictures and the words below, can you talk something about sandstorm?Ss: Yes.T: Now discuss with your group members.T: OK, who can try?S1

12、 of trees and forests. But people needed some wood to build houses and do other things, so they cut down the trees day by day. And the forests have gone slowlyS2: 引導(dǎo)學(xué)生通過圖片和短語提示，正確排列圖片順序，對沙塵暴形成的過程進(jìn)行描述，訓(xùn)練學(xué)生連詞成句，連句成片的能力。為了降低難度，可以這樣操作：先讓小組內(nèi)的每個成員根據(jù)提示詞寫一個或者幾個相關(guān)的句子，再一起將這些句子串起來，最后注意加上正確的連接詞。在展示環(huán)節(jié)，可以讓學(xué)生以小組為單

13、位，一起上臺做一個關(guān)于沙塵暴的presentation，展示小組合作的成果，體現(xiàn)小組的風(fēng)采。4While-listening (8 mins)Individual workPair workStep 1: Present the picture in 1a.

17、e earth away.通過課文插圖，引導(dǎo)學(xué)生預(yù)測課文內(nèi)容，為完成聽力降低難度。1b的聽力是抓對話的主題，不能直接找到主旨句，而是要通過歸納的方式得出，如果教師提示學(xué)生用“排除法”，可以幫助學(xué)生作出正確的選擇。如果學(xué)生基礎(chǔ)較好，也可以將1c調(diào)整成聽的活動，學(xué)生能夠找到答案，但會很難記下來。因此，可以用聽讀結(jié)合的方式，先聽兩遍，記下關(guān)鍵詞，再通過朗讀，檢查答案。5Post-listening (10 mins)Group work Group workClass activity Step 1: Let the Ss read 1a in groups and then role play i

18、t.T: Read 1a with your group members and act it out.Step2: Let the Ss read again and find the important phrases in 1a.

21、trees that the land has changed into desert.S2: , so the wind always blows the earth away.S3: , so we must do something to reduce it.S4: S5: Read 1a in groups and then role play it.

22、water.Complete the sentences with the correct forms of the given phrases in the box in 2.S1: People have cut down such a large number of trees that the land has changed into desert.S2: , so the wind always blows the earth away.S3: , so we must do something to reduce it.S4: S5: 在處理知識點(diǎn)時，教師要讓學(xué)生自己去發(fā)現(xiàn)重難點(diǎn)

23、，這有助于學(xué)生調(diào)整復(fù)習(xí)方向。如果他們組呈現(xiàn)的都是本課的重點(diǎn)知識，教師要給予肯定和鼓勵。在講解過程中，注意綜合所有小組的重點(diǎn)，并讓學(xué)生自己想辦法解決，通過造句等方式在情境中來運(yùn)用該知識點(diǎn)。在處理完課文知識點(diǎn)后，檢驗學(xué)生學(xué)習(xí)情況最好的方式就是做題，本課2，就是對1a知識點(diǎn)的鞏固訓(xùn)練和學(xué)習(xí)情況的檢測，也是提高學(xué)生綜合運(yùn)用語言的能力。6Finishing Task 4 (10 mins)Class activityLead the Ss to look at the phrases.
