③twenty_ninety表示“几十”，构成特点是都以一ty结尾。要特别注意forty(四十)的拼写。
④“几十几”的表达方式：整十位数+连字符+个位数。
如： 21 twenty-one 45 forty-five 56 fifty-six 87 eighty-seven
98 ninety-eight 38 thirty-eight
⑤一百可以用a hundred，也可以用one hundred来表示。 【拓展】基数词顺口溜： 0到12特殊记，l3到19来加teen，20到90来加ty；若是遇到几十几，十位个位问要加你一“-”。 (2)基数词的用法： ①修饰可数名词复数，要注意数词和名词的数要保持一致。如： There are two cups on the table桌子上有两个杯子。 ②“hundred／thousand(千)／million( 百万)等词的复数形式+of”可以用来表示大量的、不太确定的数目。如： Hundreds of people are in the shop．成百上千的人在商店里。
知识点2：如何写好一篇促销文章
Mr. Cool’s Clothes Store
Come and buy your clothes at our great sale! We sell all our clothes at very good prices. Do you like sweaters? We have red and green sweaters for only $15! Yellow and white sweaters are only $12! Do you need trousers? For buys, we have black trousers for only $22. And shorts are only $16! For girls, we have skirts in red and purple for only $20. How much are our jackets? Only $30! And we have black and brown shoes for only $28. Socks are only $2 for three pairs！ Come to Mr. Cool’s Clothes Store now!
根据这篇课文，总结以下要点：
1 首先开篇点明你的店现在正在促销，is on sale
2 可以设置一些自问自答的句子，例如： Do you like sweaters? We have red and green sweaters for only $15!
3 讲明你的店里有哪些物品，价格如何，用only表达价钱只有多少，表达价钱低
4 最后呼吁号召大家来你的店里买东西吧 例如：Come to Mr. Cool’s Clothes Store now!
