4B Unit 4 Buying fruit（Period1）
教材分析：本單元主要是學(xué)習(xí)句子what are these/those? they're...。book4a中已經(jīng)出現(xiàn)的句式，還可以通過單復(fù)數(shù)形式比較出它們之間的區(qū)別。
本單元主要出現(xiàn)的水果類單詞，除grapes是第一次出現(xiàn)以外，其余七種均在book3a第三單元中出現(xiàn)過。本單元出現(xiàn)的是這些單詞的復(fù)數(shù)字形式，涉及到詞形、讀音的變化，是教學(xué)中的難點(diǎn)。
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?等。在教學(xué)中教師要注意創(chuàng)設(shè)購物情景，讓學(xué)生熟練自如地運(yùn)用這些購物的基本用語。
