基数词
观察思考
阅读下面的句子，思考并完成后面的探究总结
There are thirty days in April.
四月份有三十天。
Ann is thirteen and her father is forty．
安十三岁，她爸爸四十岁。
探究总结　 基数词的用法
我们把表示数目多少的词叫作基数词。
(1)0-12是独立的单词，需要逐一记忆。
(2)13-19由其个位数后加 构成，但是注意 thirteen, fifteen, eighteen的拼写形式。
(3)20-90整十位数，以 结尾，但应注意twenty, thirty, forty, fifty, eighty的拼写形式。
(4)表示“几十几”用整十位数加上个位数，中间用连字符“-”连接起来。
【助记】
英语数词不难记，找出规律就容易。
零至十二样各异，一个一个单独记。
后加-teen变十几，thirteen，fifteen看仔细。
eight原本就有t，eighteen只缺een。
二十至九十后加-ty，twenty不同重点记。
forty去掉字母u，thirty，fifty更出奇。
十位数后个位数，表示数值几十几。
按序排列不费力，连字符号莫丢弃。
巧学巧记加努力，hundred是你的好成绩。

A math problem
Bill is an intelligent① boy. He likes to study math, and he can do all of the math problems② in his book easily.
One day on his way to school, Bill passed a fruit store. The apples in it were very nice, so Bill went in and asked, “How much are the apples？”
“Six for five cents.”
“But I don’t want six apples.”
“How many apples do you want？”
“It is not a question of how many apples I want. It is a problem in math.”
“What do you mean by a problem in math？” asked the man.
“Well, if six apples are worth③ five cents, then five apples are worth four cents, four apples are worth three cents, three apples are worth two cents, two apples are worth one cent and one apple is worth nothing. I only want one apple, and if one apple is worth nothing then it is not necessary for me to pay you.”
Bill picked out a good apple, began to eat it, and walked out of the store. The man looked at the boy with such surprise that he couldn’t say a word.

①intelligent adj. 聪明的
