《How much are these socks?》PPT课件7
Write the numbers in 1a next to the correct word. Which rows of numbers are in the wrong places?
拓展
下面把100以内的基数词分为四类。
1、第一类：
one 一 two 二 three 三 four 四
five 五 six 六 seven 七 eight 八
nine 九 ten 十 eleven 十一 twelve 十二
这一类共计十二个单词，在结构上与其他的基数词相比较是特殊的，就象不规则的动词一样，要求逐个的硬背下来，这对学好其他的基数词和序数词都是及其重要的。
2、第二类：
thirteen 十三 fourteen 十四 fifteen 十五
sixteen 十六 seventeen 十七 eighteen 十八 nineteen 十九
这一类基数词共有七个。它们在结构上有两个特点：
一是在发音方面都有两个重音；
二是在拼法上都有后缀-teen。除了thirteen和fifteen之外，都是纯粹地在另一个基数词的后面加上后缀-teen。但要注意eighteen的拼法，eight本身有t字母，因此只加-een。
3、第三类：
twenty 二十 thirty 三十 forty 四十
fifty 五十 sixty 六十 seventy 七十
eighty 八十 ninety 九十
这类基数词共有八个。都是十位的整数，均以后缀-ty结尾。其中sixty、seventy、eighty、ninety基本上是在相应的基数词后面加上后缀-ty。但要注意eighty的拼法，eight本身有t字母，因此只加-y。

Explanation
Can I help you?本意是“我能帮助你吗？”， 但在不同的语言环境中，翻译有所不同。在商场里，服务员说“Can I help you?”可以翻译为“你要买点什么？”， 在餐厅里则可译为“你要吃点什么？”等。用于对顾客的有礼貌的打招呼。类似的表达还有：
What can I do for you? 你需要点什么？
May I help you? 你要点什么
