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，讓學生對這種天氣，有所了解，然后在進入1a，詳細談論沙塵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。3

10、Pre-listening (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.

12、e lots 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: 引導學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行描述，訓練學生連詞成句，連句成片的能力。為了降低難度，可以這樣操作：先讓小組內的每個成員根據提示詞寫一個或者幾個相關的句子，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

13、生以小組為單位，一起上臺做一個關于沙塵暴的presentation，展示小組合作的成果，體現(xiàn)小組的風采。4While-listening (8 mins)Individual workPair workStep 1: Present the picture in 1a. Let the Ss listen to 1a once and do 1b alone.T: Right.

17、ing the earth away.通過課文插圖，引導學生預測課文內容，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，如果教師提示學生用“排除法”，可以幫助學生作出正確的選擇。如果學生基礎較好，也可以將1c調整成聽的活動，學生能夠找到答案，但會很難記下來。因此，可以用聽讀結合的方式，先聽兩遍，記下關鍵詞，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

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

23、去發(fā)現(xiàn)重難點，這有助于學生調整復習方向。如果他們組呈現(xiàn)的都是本課的重點知識，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，并讓學生自己想辦法解決，通過造句等方式在情境中來運用該知識點。在處理完課文知識點后，檢驗學生學習情況最好的方式就是做題，本課2，就是對1a知識點的鞏固訓練和學習情況的檢測，也是提高學生綜合運用語言的能力。6Finishing Task 4 (10 mins)Class activityLead the Ss to look at the phrases.
