（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12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。03 知识归类 知识网络化基数词的构成分类图解one 1two 2three 3four 4five 5six 6seven 7eight 8nine 9ten 10eleven 11twelve 12thirteen 13fourteen 14fifteen 15sixteen 16seventeen 17eighteen 18nineteen 19twenty
