資源簡介

Unit 4 Amazing Science Topic 2Section D（教學(xué)設(shè)計）
Ⅰ. Material analysis
本課主活動是1a和Project?！罢Z法和功能”部分讓學(xué)生總結(jié)歸納一般將來時的被動語態(tài)。1a 繼續(xù)學(xué)習(xí)宇宙知識并講述了人類探索宇宙的活動。在這個部分還留下了一個懸念：茫茫的宇宙中還有其他生命存在嗎？很好地激發(fā)了學(xué)生探索宇宙的欲望。1b這個圖表型的任務(wù)可以看作是一個跨學(xué)科銜接。地理知識好，不用看1a 也能完成，否則必須把1a讀懂才能完成。3是個有趣的活動。學(xué)生在展開想象的同時可以順便復(fù)習(xí)將來時的被動語態(tài)。本課的Project不再是寫作任務(wù)，而是口語活動任務(wù)。以學(xué)生現(xiàn)有的知識不難完成此任務(wù)。2是個寫作任務(wù)，讓學(xué)生描寫“地球”。由于寫作需要較長的時間，故把2留作家庭作業(yè)。
