Unit3 At the zoo教案教学目标：1.能听、说、读、写单词：big, small, long, short. 2.能听懂形容词的意思，并能根据指令性语言做出正确的动作。3.培养学生热爱自然，爱护小动物，热爱生活的积极情感。教学重点：1.单词big, small, long, short的音、形、义、用；2.能听懂会说句型It has ,区别使用Its和It has 。 教学难点：利用所学形容词熟练自如地描述各种动物。教学准备： 动物图片、课件、单词卡片教法与学法：本节课我主要采用了任务型教学法，以make a ostrich为主线任务，引出形容词，操练形容词和句子。同时在和黄老师商量之后，我们提前布置了让孩子们带上自己动物玩偶，让孩子们在巩固扩展环节能够运用所说句子和单词说一说动物。激发他们的兴趣，让他们有兴趣地说，有信心地说。教学过程：1.
