7、基数词一、基数词的构成：(1)1-12的基数词是独立的单词，即(2)13-19的基数词均以-teen结尾，即(3)20-29的整十位均以-ty结尾，即(4)十位数与个位数之间要加连字符号“-”，如：28twenty-eight 96ninety-six(5)百位和十位(若无十位则和个位)之间加and。如：138one hundred and thirty-eight 405four hundred and five(6)整数单位：hundred(百)，thousand(千)，ten thousand(万)，one hundred thousand(十万)，million(百万)，ten mil

8、lion(千万)，a hundred million(亿)，billion(十亿)。(7)在英语中，1000以上的阿拉伯数字，从后往前数每三位加一个逗号“，”。如： 4,256,392four million, two hundred and fifty-six thousand, three hundred and ninety-two.one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve。thirteen, fourteen, fifteen, sixteen, seventeen,eightee

9、n,nineteentwenty, thirty, forty, fifty, sixty, seventy, eighty, ninety.【注意】hundred, thousand, million, billion等前面有具体的数词时，不能在它们的后面加s。 但是用来表示不确定数目时，要用其复数形式，且后面需加of。如：five hundred 五百 six million 六百万 thousands of 成千上万的。【典例】_ people come to see our play(表演). Its so great. A. Hundred B. Hundreds C. Hundre

10、d of D. Hundreds ofD2.基数词的用法（1）作主语。(主语是执行句子的行为或动作的主体 )如：12是一个很重要(important)的数字。Twelve is a very important number.（2）作定语(定语是用来修饰、限定、说明名词或代词的品质与特征的 )。如：我有两个姐姐。I have two sisters. （3）作宾语(宾语，又称受词，是指一个动作（动词）的接受者 )。如：Give me two, please.（4）作表语(表语是用来说明主语的身份、性质、品性、特征和状态的 )。如：What time is it?Its six.（5）作同位语(

11、一个名词(或其它形式)对另一个名词或代词进行修饰，限定或说明，这个名词（或其它形式）就是同位语)。如：你们两个在做什么？What are you two doing ?二、序数词用来表示顺序的数词叫序数词。1.序数词的构成(1)一般来说，序数词是由相应的基数词在词尾加th构成。如fourfourth,six sixth, seven seventh, eleven eleventh , hundred hundredth, thousand thousandth, million millionth.(2)下面这些基数词在变为序数词时，有特殊的变化。如：one first, two secon

12、d, three third , five fifth, eight eighth, nine ninth , twelve twelfth.(3)十位整数序数词的构成方法是将基数词的词尾y，变为ie，然后再加th。如：twenty twentieth, thirty thirtieth, forty fortieth , ninety ninetieth.(4)两位或两位以上的基数词变为序数词时，仅将个位数变为序数词。如：twenty-one twenty-first, forty-four forty-fourth, two hundred and thirty-three two hun

13、dred and thirty-third.其规律可以用下面口诀记忆：基变序，有规律，结尾加上th， 1、2、3，特别记，first，second，third。8去t，9去e，f代ve， y变为ie，词尾要加th。 若是遇到几十几，只变个位就可以。【注意】(1)在使用序数词时，一般在其前加上定冠词the。如：the first book（第一本书）， the fourth week （第四周）(2)序数词与定冠词、物主代词或名词所有格等连用表示顺序；与不定冠词连用，表示“再一，又一”的意思。如：I am often the first to get to work in my office.在

14、我们办公室，我是经常第一个上班的。Try it a second time.再试一次。【典例】Mike has _ elder brothers. Hes his fathers _ son. A. two; third B. two; three C. second; third D. second; threeA三、数词的常用表达1.年份的读法用基数词，分成两位一读，也可以用thousand或hundred来读。如1998 nineteen eighty-nine；2010 two thousand and ten；1900 nineteen hundred。2.年、月、日的顺序 英语中，

15、可以按“月、日、年”的顺序来表示，也可以按“日、月、年”的顺序来表示。如“1999年6月1日”可以写成“June 1st，1999”或“1st June 1990”读作“June (the) first, nineteen ninety-nine”或“the first of June,nineteen ninety-nine”3.时刻表达法英语中时间是用基数词来表示的，最常见的形式有两种：(1)先点钟，后分钟。如6:30 six thirty; 7:54 seven fifty-four(2)先分钟，后点钟。分钟数不超三十分钟时(包括三十分钟)，用“分钟数+past+钟点数”表示；分钟数超过

16、三十分钟时，用“(60分钟数)+to+下一个钟点数”表示，即“差几分到几点”。如6:20 9:47 twenty past six thirteen to ten(3) “整点”，直接用“钟点数(+oclock)”表示。“半小时”用half an hour表示，“一刻钟”用a quarter 表示。 如6:00 six (oclock), 7:30 half past seven, 5:45 a quarter to six 8:15 a quarter past eight.【注意】一般使用half时，都与past连用，而不加to。4.年龄表达法(1)年龄可以用下列结构表示。如： 她九岁了。

17、She is nine years old./ She is nine years of age./ She is aged nine (years).她是一个九岁的女孩儿。She is a nine-year-old girl.(2) at the age of表示“在某人几岁”时。“in+ones+整十数的复数形式”表示“某人几十多岁”。如：他祖父六十多岁了。His grandfather is in his sixties.When she was at the age of six, she was so lovely. 5.表示编号编号可以用基数词表示，也可以用序数词表示。用基数词表

18、示是，要将基数词放在被修饰词之后，且首字母都用大写；用序数词表示时，要将序数词放在被修饰的名词前，且要加上定冠词the。如： 第三单元 the third unit / Unit Three【注意】(1)表示房间时不用“No”，而是将room作为单位词放在数字前，大写首字母。如：303房间 Room 303 (读作：room three o three)(2)如果编号的数字比较长，一般使用阿拉伯数字。如Page 626(第625页)。 6.次数的表达法在英语中“一次”、“两次”分别用once和twice来表示；表示三次以上则用“基数词+times”。如：We travel to other countries three times
