2024年人教版中考二轮复习 专题六 数词练习（含答案）

人教版中考二轮复习 专题六 数词 数词的分类：数词分为基数词和序数词。基数词表示数目的多少。序数词表示事物的先后顺序，往往与定冠词the连用。 一、基数词的构成 (1)0—12单独记。 (2)13—19的词尾都是teen。 (3)20以上的整十的基数词均以ty结尾。 (4)＂几十几＂要加连字符号＂-＂。 (5)＂几百几十＂或者＂几百几十几＂在＂百＂后加and。 (6)四位数或者四位数以上的基数词的拼写规律：用逗号从右往左每三位加一个逗号，第一个逗号读作thousand(千)，第二个逗号读作million(百万)，第三个逗号读作billion(十亿)，hundred后莫忘＂and＂。 二、序数词的构成 (1)＂第一＂、＂第二＂、＂第三＂分别是first, second, third。 (2)＂第四＂到＂第十九＂除了fifth, eighth, ninth, twelfth是特殊的拼写外，其余的都在相应基数词后面加＂th＂构成。 (3)20以上的整十的序数词由相应的基数词变y为i，再加＂-eth＂。 (4)第一百hundredth; 第一千thousandth; 第一百万millionth。 (5)20以上的非整十的基数词变序数词时，只变化个位数。 三、分数的表达法 分数是由基数词作分子，序数词作分母构成的。除了分子是＂1＂的情况外，序数词都要用复数。 练习 1. —Dear, how is your homework going —Oh, mom, I've just finished of it.
