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(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 二十個蘋果 thirty-three eggs 三十三個雞蛋.強(qiáng)化鞏固1.

Theyre Come and buy your clothes at our great sale. 四、【教后反思】本節(jié)課的重點內(nèi)容是基數(shù)詞的表達(dá)和衣服店的打折廣告。對于七年級的學(xué)生而言，基數(shù)詞的表達(dá)小學(xué)時都接觸過了，只是如何書寫，學(xué)生可能記的不太牢固。對于衣服打折的說法，學(xué)生在這之前只學(xué)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(xué)生以前沒有接觸，所以，要加強(qiáng)這些短語和用法的練習(xí)。
