Some important points.1. 基數詞的表達1) one到twelve, 拼寫和讀音無規(guī)律可言, 只能逐一記憶。2) thirteen到nineteen，表示“十幾”，在個位數后加后綴-teen，其中要注意thirteen, fifteen和eighteen的拼寫。3) twenty到ninety，表示“幾十”，以ty結尾，但需注意twenty，thirty, forty, fifty, eighty的拼寫。 4) 2129 直到9199，表示“幾十幾”，用整十位數加個位表示， 中間用連字符“-
9、” 把十位和個位連接起來。 5) one hundred 意為 “一百”，也可說a hundred，hundred可加具體數字，如nine hundred (900)。2. 基數詞的用法： 基數詞只能修飾可數名詞，要注意數詞和名詞在數上要保持一致。如：one student 一名學生 two boys 兩名男孩twenty apples 二十個蘋果 thirty-three eggs 三十三個雞蛋.強化鞏固1.

12、according to 2b.三、【板書設計】Unit 7 How much are these socks?Section B 1a-2c tenninety-nine How much is? Its How much are? Theyre Come and buy your clothes at our great sale. 四、【教后反思】本節(jié)課的重點內容是基數詞的表達和衣服店的打折廣告。對于七年級的學生而言，基數詞的表達小學時都接觸過了，只是如何書寫，學生可能記的不太牢固。對于衣服打折的說法，學生在這之前只學過描述物品價格的說法，對于一些短語像at very good prices和 at our great sale,學生以前沒有接觸，所以，要加強這些短語和用法的練習。
