数词是历年中考试题中的必考知识点之一，但所占分值不多，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，涉及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、分数表示法等。预计2022年中考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，billion的用法。

特例清单
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
She is going to try a third time.她准备再试第三次。
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，不需要添加定冠词。如：
the first page=Page 1
3.表示年、月、日时，年用基数词，日用序数词。如：July 1st,1949读作July the first,nineteen forty-nine.
4.表示分数时，分子用基数词，分母用序数词，当分子大于1时，分母用复数形式。如：one third,five sixths
【注意】分数作主语时，谓语动词的单复数由of后面的名词的数来确定。of后面的名词为可数名词复数时，谓语动词用复数形式；of后面的名词为不可数名词时，谓语动词用单数形式。如：
Two thirds of the work is hard to finish.三分之二的工作很难完成。
