They’re…。Book4A中已经出现What’s this/ that? It’s…句型。教学中教师可以采用以旧带新的方法，从单数句式引出复数句式，还可以通过单复数形式比较找出它们之间的区别。本单元主要出现了水果类单词，除lemons, strawberries, grapes三种水果是第一次出现以外,其余八种均在Book3A第三单元中出现过。教师可通过句型Do you like …? Yes, I do./ No, I don’t.的问答教授这三个新单词,并适当补充一些学生感兴趣的水果单词,如甘蔗(sugar cane),荔枝(lichee)等等。本单元出现的是这些单词的复数形式，涉及到词形、读音的变化，是教学中的难点。教师可以对名词复数的词形和读音进行归类。与本单元所出现的水果类单词紧密结合的是在商店里购物的常用语Can I help you? How many kilos? These or those?等。在教学中教师要注意创设购物情景，让学生熟练自如的运用这些购物的基本用语。另外可以根据学生的具体情况适当补充一些其他购物用语或让学有余力的学生课后去收集这类交际用语，以扩充他们的知识面、锻炼他们的自主学习能力。四、课时安排: 四课时五、教学过程设计：Period 1Teaching aims and difficulties:1. 能听得懂、会说、会读和会拼写单词apples, oranges, bananas, peaches, grapes, watermelons, pears。能听得懂、会说、会读单词pineapples, lemons, strawberries, mangoes。2. 能听得懂、会说、会读和会写句型What are these/those?
