T: What fruit do you like? S: I like….看图说说自己喜欢的水果(复习旧句型,并帮学生复习三年级学过的水果类单词。看看学生能说上来几个水果类的单词)
当学生看图说:I like peras 时  教授单词“pears ”(这课时的重点水果类的复数,三年级只学了水果的单数,所以课文出现单词“pears”还是要教)
手拿实物 a pear  T: what’s this ?  S: It’s a pear.
         pears   T: What are these ? S: They’re pears.( PPT呈现图和板书区别句型的单复数,做个比较,比较形象)
3、PPT切换水果 用What are these ? They’re….操练句型。师和生,生和生之间一问一答。当生在远处指着PPT问What are these ?时,师立即纠正 T:You should say“What are those?” 师教授“those”同样PPT 呈现板书区别that和those。
(these和those的读音学生可能会发音不准,可多读几遍)
用“What are those?”问学生引出“grapes”的教授。
句型What are these/those ?They’re …s /es.操练。Work in pairs.

(PPT呈现两个称上面分别放了一些梨和一些葡萄)指着图问How many kilos does Miss Li buy? Boys and girls ,do you remember? Don’t worry .let’s watch the cartoon again,then answer my questions.
给学生播放A部分动画。生看后回答问题 .
PPT呈现几张水果图,用how many kilos ?...kilos .进行问答。(这个环节不但巩固了学生对买东西日常对话的运用还要学生注意一公斤是one kilo,大于等于二公斤才可….kilos )
