Some important points.1. 基數(shù)詞的表達(dá)1) one到twelve, 拼寫和讀音無(wú)規(guī)律可言, 只能逐一記憶。2) thirteen到nineteen，表示“十幾”，在個(gè)位數(shù)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(jié)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(shù)加個(gè)位表示， 中間用連字符“-” 把十位和個(gè)位連接起來(lái)。 5) one hundred 意為 “一百”，也可說(shuō)a hundred，hundred可加具體數(shù)字，如nine hundred (900)。2. 基數(shù)詞的用法： 基數(shù)詞只能修飾可數(shù)名詞，要注意數(shù)詞和名詞在數(shù)上要保持一致。如：one student 一名學(xué)生 two boys 兩名男孩twenty apples 二十個(gè)蘋果 thirty-three eggs 三十三個(gè)雞蛋.強(qiáng)化鞏固1.

Theyre Come and buy your clothes at our great sale. 四、【教后反思】本節(jié)課的重點(diǎn)內(nèi)容是基數(shù)詞的表達(dá)和衣服店的打折廣告。對(duì)于七年級(jí)的學(xué)生而言，基數(shù)詞的表達(dá)小學(xué)時(shí)都接觸過(guò)了，只是如何書寫，學(xué)生可能記的不太牢固。對(duì)于衣服打折的說(shuō)法，學(xué)生在這之前只學(xué)過(guò)描述物品價(jià)格的說(shuō)法，對(duì)于一些短語(yǔ)像at very good prices和 at our great sale,學(xué)生以前沒(méi)有接觸，所以，要加強(qiáng)這些短語(yǔ)和用法的練習(xí)。
