(對劃線部分提問) _ _ the battery-operated slippers _ _ ? homework:1. you have to do read the text after the tape and try to recite 2d.2. you may do write your ideas about your own inventions in the future: 反思：本節課主要是在不斷地聽和對話訓練中讓學生掌握有關被動語態的有關知識，學習用what,when引導的特殊疑問句，詢問距離及所用時間及其相應的回答。但學生對本課中的三種交通工具的表達方式的用法易混淆，還需要繼續進行練習。亮點：1. 本課的導入。通過學唱chant，吸引學生的注意力，輕松熱身，并引出本課的的目標語言。2. 本課的角色表演。語言學習的最終目的是為了應用，要多為學生提供真實的語言環境，讓學生用英語處理生活中的實際問題。不足：本節課由于內容過多，所以操練部分練習的不夠充分answers: preview:phrases 1 was invented 2 shoes with special heels 3 shoes with lights4 runs on electricity 5 the style of the shoes 6 be used 7 my pleasure 8 such a great invention 9 in our daily lives 10 wa
