Unit3 At the zoo B Lets learn 海城镇德荥学校 陈嘉曼1、 教学内容：1. 单词:big, small, long, short.2. 句型It has.二、教学目标：1.能听、说、认读单词:big, small, long ,short，并能这些单词来描述动物形态特征。2.能够听懂、会说句型It has .3.激发学生充分动用已学过的知识，进行发散性认识。 三、学情分析： 学生在本单元前一、二、课时已经学习过形容词thin，fat, short, tall以及句型Its 。在新的课堂能在语境下整体感知了long， short，big , small的音和义，以及It has句型的表达。于是在设计这堂课时，我尽可能让课堂变得有趣起来，在操练环节多采用听、说、游戏的方式，让学生能动起来，充分参与到课堂中来。为了让呈现部分更有趣更直观一点，我设计了一个大鸵鸟，用鸵鸟的几个身体特征引出It has.的句型描述。四、教学重难点：1.单词big, small, long, short的音、形、义、用；能听懂会说句型It has ,区别使用Its和It has 。2. 教学难点：利用所学形容词熟练自如地描述各种动物。单词small 中 l 的发音，舌头要上卷.Short 的两种意思。五、教学准备：课件、多媒体、词卡、图卡、装有玩偶的箱子。六、教学过程：(一) Warming up1.
