8、境問(wèn)題做好準(zhǔn)備。教師在教讀單詞時(shí)，注意使用升調(diào)和降調(diào)，配上手勢(shì)，培養(yǎng)學(xué)生的語(yǔ)音語(yǔ)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?

12、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(dǎo)學(xué)生通過(guò)圖片和短語(yǔ)提示，正確排列圖片順序，對(duì)沙塵暴形成的過(guò)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(gè)成員根據(jù)提示詞寫一個(gè)或者幾個(gè)相關(guān)的句子，再一起將這些句子串起來(lái)，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

13、小組為單位，一起上臺(tái)做一個(gè)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、the earth away.通過(guò)課文插圖，引導(dǎo)學(xué)生預(yù)測(cè)課文內(nèi)容，為完成聽力降低難度。1b的聽力是抓對(duì)話的主題，不能直接找到主旨句，而是要通過(guò)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(dòng)，學(xué)生能夠找到答案，但會(huì)很難記下來(lái)。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(guò)朗讀，檢查答案。5Post-listening (10 mins)Group work Group workClass activityStep 1: Let the Ss read 1a in groups and then role play

18、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、，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(shí)，教師要給予肯定和鼓勵(lì)。在講解過(guò)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(guò)造句等方式在情境中來(lái)運(yùn)用該知識(shí)點(diǎn)。在處理完課文知識(shí)點(diǎn)后，檢驗(yàn)學(xué)生學(xué)習(xí)情況最好的方式就是做題，本課2，就是對(duì)1a知識(shí)點(diǎn)的鞏固訓(xùn)練和學(xué)習(xí)情況的檢測(cè)，也是提高學(xué)生綜合運(yùn)用語(yǔ)言的能力。6Finishing Task 4 (10 mins)Class activityLead the Ss to look at the phrases.
