（四）数词
01 命题趋势 考标导向化
数词是历年中考试题中的必考知识点之一，所占分值不多，一般在1～2分之间，题型有选择题、词形变换题等。从命题内容来看，对基数词和序数词的基本用法、hundred, thousand, million, billion后面加不加-s或of、特殊形式的序数词、分数表示法的考查是中考命题的热点。预计2015年考查的重点极有可能是基数词和序数词的用法、分数表示法及hundred，thousand，million的用法。
02 定义 概念清晰化
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。

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
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)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)five./Three and two makes five.
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.
10÷5=2读作Ten divided by five equals(或is)two.
5.“基数词+more”或“another+基数词”表示“在原来的基础上增加的数量”。如：
My grandmother will stay in Shanghai for two more weeks.
=My grandmother will stay in Shanghai for another two weeks.我的奶奶将在上海再待两周。
