数词讲解
定义
数词就是用于表示数目的多少或顺序的先后的词，分为基数词和序数词两种。表示数量的数词是基数词，如one,?two,?three等；表示顺序的数词是序数词，如first,?second,?third等。21·cn·jy·com
基数词
1.1000以上的基数词的表示方法是：从右向左用分节号“，”分节，每三个数字为一个节，第一个分节号前用thousand，第二个分节号前用million，第三个分节号前用billion?(美)或thousand?million(英)。?如：2，418，000，000?two?billion,?four?hundred?and?eighteen?million或21世纪教育网版权所有
two?thousand,?four?hundred?and?eighteen?million
2.hundred,thousand,million,billion等用在具体的数字后面时不能加-s或of；hundred,?thousand,?million,?billion等前面没有具体的数字时通常加-s或of。如：?eight?thousand?people八千人，?fifty?thousand?trees五万棵树，thousands?of成千上万的，【来源：21·世纪·教育·网】
?millions?of数百万
3.“基数词+单数名词”相当于复合形容词，作名词的定语，用于表示时间、距离等。如：
?the?100-metre?race?100米赛跑，a?ten-minute?walk? 10分钟的路程，
4.常见的数字符号和等式的读法：=(等于号)读作equals，+(加号)读作plus或and，-(减号)21·世纪*教育网
读作minus，×(乘号)读作times?或multiplied?by，÷(除号)读作divided?by。
如：3+2=5读作Three?plus?two?equals (或is) five. / Three?and?two?is (或equals或makes) five. 2-1-c-n-j-y
5-3=2读作Five?minus?three?equals(或is)two；
8×7=56读作Eight?times?seven?equals(或is)fifty-six./ Eight?multiplied?by?seven?is?fifty-six.?21*cnjy*com
10÷5=2读作Ten?divided?by?five?equals(或is)two.?
“基数词+more”或“another+基数词”表示“在原来的基础上增加的数量”。
如：?我的奶奶将在上海再待两周。
My?grandmother?will?stay?in?Shanghai?for?two?more?weeks.?【版权所有：21教育】
=My?grandmother?will?stay?in?Shanghai?for?another?two?weeks.21cnjy.com
序数词
1.序数词在使用时，通常前面要加定冠词the；但是如果序数词前出现不定冠词a或an时,则表示“再一”，“又一”。如：21教育名师原创作品
We’ll?go?over?it?a?second?time.我们得再念第二遍。
We’ve?tried?it?three?times.?Must?we?try?it?a?fourth?time?我们已经试过三遍了，还必须试一次(第四次)吗？21*cnjy*com
?
2.基数词也可以表示顺序。只需将基数词放在它所修饰的名
词之后即可，不需要添加定冠词。如：
the?first?lesson——Lesson?One?
the?fifth?page——Page?5(Five)?
the?twenty-first?room——Room?21(Twenty-one)?
