部編版語文七年級上冊《皇帝的新裝》教案
仔細思考下列問題。1.在故事情節(jié)發(fā)展中起著關鍵作用的語句是哪一句？為什么騙術能步步行通？（1）“任何不稱職的或者愚蠢得不可救藥的人，都看不見這衣服”這句話在故事情節(jié)發(fā)展中起著關鍵作用。（2）騙子胡說那件衣服具有一種“奇怪的特性”，不但抓住了皇帝的昏庸無能而又想辨別出官員是否稱職、是聰明還是愚蠢的心理，而且抓住了大臣們只想保住官位而阿諛奉承的心理，因而騙術步步行通。2.在根本不存在的“新裝”面前，從皇帝到老百姓都不敢說自己根本看不見它，這是為什么？因為騙子說“任何不稱職的或者愚蠢得不可救藥的人，都看不見這衣服”，大臣們怕人說自己不稱職，百姓怕人說自己愚蠢，皇帝既怕被人說不稱職，又怕給人說愚蠢，所以都不敢說真話了。3.后來，一個小孩子最先說出了真話，緊接著老百姓也都說真話了，而皇帝和他的內臣們仍裝模作樣地把戲演下去。作者這樣寫，你是怎樣理解的？
