基数词
1.概念
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
(1)one—twelve， 无规律可言，应当逐一记忆。
(2) thirteen—nineteen，表示“ 十几”， 在个位数后加后缀-teen, 读
/ti n/，但要注意下面几个词的拼写：thirteen(13), fifteen(15), eighteen(18)
(3) twenty 到ninety，表示“ 几十”， 以-ty 结尾，但需注意下面几个词的拼写：twenty(20),thirty(30), forty(40), fifty(50), eighty(80)。
(4) “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)。
(5) 一百的表达方式为one hundred 或a hundred。 要表示“几百”，用具体数字加上hundred，如five hundred(500)，注意此时的hundred 是单数形式。表示“几百几”时，要在百位数和十位数( 或个位数) 之间加and。如：one hundred and two(102)。
基数词记忆规则歌诀：
基数词不难记，找出规律很容易：
零至十二形各异，加上-teen 为十几；
thirteen, fifteen看仔细，eighteen只有一个t；
twenty 却是很奇怪，forty 本身也不乖，
eighty 一起搞例外，跟着也把规则坏；
十位后面是个位，表示数字“几十几”；
表示“几百几十几”，and 常把百、十系。
勤学妙记加练习，hundred就是你的好成绩。
3.基数词的用法
表示数量，置于名词之前。 She has two brothers.她有两个弟弟。
表示编号，置于名词之后。 They are in Class Five.他们在五班。
表示号码。 His phone number is 337-5683.
他的电话号码是337-5683。
表示时间。 It’s 10:00 now. 现在是10 点。
表示年龄。 My sister is 8 years old. 我妺妺8 岁了。
用于计算。 Two and four is six. 2加4等于6。
基数词只能修饰可数名词，要注意基数词和名词在数上要保持一致。
e.g. one banana 一根香蕉 five boys 五个男孩
【难点】hundred, thousand, million等与具体数字连用时，用单数形式，且后不接介词of；当其前面没有具体数字时，要用复数形式，且后面要加of。
e.g. three hundred teachers 三百位老师
hundreds of students 数百名学生
how much 常用于询问某物的价格，其结构为“How much ＋ be 动词＋主语 ”。
①当主语是可数名词单数或不可数名词时，be 动词用is，答语为：“It’s...”；
②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。
How much
③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)……”。
