Unit 4Buying fruit一、本單元教學(xué)內(nèi)容類別語音項目要求語音輔音字母組合th在單詞中的發(fā)音聽讀、辨認詞匯apples, oranges, bananas, peaches, grapes, watermelons, pears, some聽得懂、會說、會讀、會拼寫日常交際用語Can I help you?These or those?聽得懂、會說、會讀句型What are these/ those?Theyre.How many kilos? kilos, please.聽得懂、會說、會讀、會寫歌謠會朗誦二、本單元教學(xué)重點和難點：* 1.能聽得懂、會說、會讀和會拼寫單詞apples, oranges, bananas, peaches, grapes, watermelons, pears, some。2.能聽得懂、會說和會讀日常交際用語Can I help you? These or those?* 3.能聽得懂、會說、會讀和會寫句型What are these/those? Theyre. How many kilos? kilos, please.* 4.初步掌握名詞復(fù)數(shù)的詞形和讀音的變化。5.了解輔音字母組合th在單詞中的兩種不同讀音。6.能有表情地流利的誦讀歌謠I like fruit。（ p.s.*為教學(xué)難點， 為教學(xué)重點。）三、教材內(nèi)容分析:本單元的核心教學(xué)內(nèi)容是“認物”，主要學(xué)習(xí)句子What are these/ those? Theyre。Book4A中已經(jīng)出現(xiàn)Whats this/ that? Its句型。教學(xué)中教師可以采用以舊帶新的方法，從單數(shù)句式引出復(fù)數(shù)句式，還可以通過單復(fù)數(shù)形式比較找出它們之間的區(qū)別。本單元主要出現(xiàn)了水果類單詞，除lemons, strawberries, grapes三種水果是第一次出現(xiàn)以外,其余八種均在Book3A第三單元中出現(xiàn)過。教師可通過句型Do you like ? Yes, I do./ No, I dont.的問答教授這三個新單詞,并適當(dāng)補充一些學(xué)生感興趣的水果單詞,如甘蔗(sugar cane),荔枝(lichee)等等。本單元出現(xiàn)的是這些單詞的復(fù)數(shù)形式，涉及到詞形、讀音的變化，是教學(xué)中的難點。教師可以對名詞復(fù)數(shù)的詞形和讀音進行歸類。與本單元所出現(xiàn)的水果類單詞緊密結(jié)合的是在商店里購物的常用語Can I help you? How many kilos? These or those?等。在教學(xué)中教師要注意創(chuàng)設(shè)購物情景，讓學(xué)生熟練自如的運用這些購物的基本用語。另外可以根據(jù)學(xué)生的具體情況適當(dāng)補充一些其他購物用語或讓學(xué)有余力的學(xué)生課后去收集這類交際用語，以擴充他們的知識面、鍛煉他們的自主學(xué)習(xí)能力。四、課時安排: 四課時五、教學(xué)過程設(shè)計：Period 1Teaching aims and difficulties:1. 能聽得懂、會說、會讀和會拼寫單詞apples, oranges, bananas, peaches, grapes, watermelons, pears。能聽得懂、會說、會讀單詞pineapples, lemons, strawberries, mangoes。2. 能聽得懂、會說、會讀和會寫句型What are these/those?
