课件每出示一张图片，放一段录音，随即然学生单独重复，即时板书dress, dresses, dish, dishes, bus, buses
(设计意图：学生听录音，模仿标准的语音语调，培养了听的习惯，同时为他们最终的说打下良好的基础。)

以同种方式教授 woman, women, child ,children 并板书

T: 第二种情况是
S: 在单词的后面加es。
T: 最后是不规则的变化，如men,women,children。我们已经学习了好多的可数名词，谁能说出一些，并说如何变成复数形式?
S: book---books toothbrush---toothbrushes chair---chairs room---rooms ……
从学生说出的众多单词中，总结名词变复数加es的规律：以”s” “sh” “ch” “x”为结尾的可数名词变复数时，在词尾后加-es 。不规则变化的单词：tooth,foot ,man,woman,children
(设计意图：在教师的引导下，让学生自己发现并总结规律，锻炼学生的自主学习意识，并体验成功的喜悦)
