Grammar
一、How much引导的疑问句：
1. how much常用于询问某物的价格，其结构为“How much +be动词+ 主语？”。当主语是可数名词或不可数名词时，be动词用is，答语为“It’s ...”；当主语是可数名词复数或不仅仅是一种东西时，be动词用are，答语为：“They’re ...”，上述两种情况都可直接回答钱数。
【中考连接】
--____ are these bananas --$2.
A. How much B. How many C. How long D. How about
B
2. 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 the book 这本书多少钱？
--It’s three dollars. 三美元。
--What’s the price of these oranges 这些橙子多少钱？
--It’s two dollars. 两美元。
二、基数词：
1. 定义：表示事物数量多少的数词叫作基数词，如one, two, three等。
2. 基数词的拼写(100以内)：
(1) one — twelve，无规律，应该逐一识记。
one (1), two (2), three (3), four (4), five (5), six (6), seven (7),
eight (8), nine (9), ten (10), eleven (11), twelve (12)
(3) twenty — ninety，表示“几十”，以-ty结尾，但需要注意twenty (20), thirty (30), forty (40), fifty (50), eighty (80)等几个单词的拼写。其余的是：sixty (60), seventy (70), ninety (90)
(4) 表示“几十几”的表达方法：用整十数加个位数表示，中间用连字符“-”把整十数和个位数连接起来。
如：twenty-five (25) sixty-eight (68)
(2) thirteen — nineteen，表示“十几”，在个位数后加后缀-teen，但要注意thirteen, fifteen, eighteen等词的拼写。
3. 基数词的用法：
①表示数量，置于名词之前。
He has two sisters. 他有两个姐姐。
②表示编号，置于名词之后。
We are in Class Eight. 我们在八班。
③表示号码。
His phone number is 555-3618. 他的电话号码是555-3618。
④表示时间。
It’s 9:00 now. 现在是9点。
⑤表示年龄。
My brother is 5 years old. 我弟弟5岁了。
⑥用于计算。
Three and five is eight. 3加5等于8。
注意：基数词只能修饰可数名词，基数词和名词在数上要保持一致。 如：one apple 一个苹果 four boys 四个男孩
