探究语法规律
What did you find out
探究一：how much,意为“多少钱”，用来询问物品的价格
how much常用于询问某物的价格，其结构为“How much ＋ be ＋主语？”。
其答语为：主语+be+价格。
Grammar Focus
How much is the/this/that + 单数名词 这一句型常用来询问价格。如果询问不可数物品或单数商品的价格, 用How much is ... 。答语为：It’s + 数额.
—How much is this T-shirt 这件T恤衫多少钱？ —It’s seven dollars. 七美元。
如果询问可数名词复数或多个可数物品的价格, 则用How much are the / these /those + 复数名词 。答语为：They’re + 数额.
—How much are these pencils 这些铅笔多少钱？ —They’re two dollars. 两美元。
探究一：how much,意为“多少钱”，用来询问物品的价格
Grammar Focus
询问商品价格时，还可以用“ What's the price of…”？句型，意为“……的价格是多少？”
无论被询问的物品是不可数名词还是可数名词的单数或复数，be动词都用is，不能用are。
其答语为：It's…“(价格是)……”
What’s the price of these shoes 这些鞋子多少钱？
It's one hundred and fifty yuan. 150元。
What's the price of these eggs 这些鸡蛋多少钱？
It's ten yuan.10元。

探究二：基数词的用法
基数词只能修饰可数名词，要注意数词和名词在数上要保持一致。
e.g. twenty apples two cups
表示编号时，用“事物+基数词”。 e.g. Room 302
表示年龄。e.g. He is fourteen years old.
表示时刻。e.g. nine twenty-eight
Grammar Focus
基数词的表达法
数字 基数词形式 例词
0-12 各自独立 zero, one; nine; twelve
13-19 3-9+重读teen结尾 特殊：thirteen; fifteen; eighteen;
一般：fourteen; sixteen
20-90整十数 以ty结尾 twenty; thirty; forty; fifty; sixty; seventy; eighty; ninety
两位数（几十几） 整十位数-个位数 twenty-one; thirty-five; ninety-eight
英语数词不难记，找出规则就容易。一至十二词各异，一个一个单独记。
后加 teen变十几，thirteen, fifteen看仔细。eighteen只有一个t，两个音节念清晰。
整十后加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，
若要表示几百几，hundred之后and立。
