1、精选优质文档-倾情为你奉上2017届初三年级英语中考第一轮总复习导学案专题四：数 词考点分析：一、考纲要求1、掌握基数词与序数词的构成2、熟练掌握年、月、日、编号、分数的表示法3、理解数词的某些特殊用法，如hundreds of, thousands of, 1990s等二、命题特点通过对近几年部分省市中考题分析，关于数词的考题比较少，主要集中在基数词和序数词的用法区别，以及分数的正确表达方式上，百、千、百万等的泛指和一些特殊表达的考查等。三、命题预测预计2017年中考命题可能会从以下几个方面考查数词：1、成百、成千等泛指的表达。2、分数的表达。3、年、月、日的表达。考点突破：表示_的词，叫数
2、词。其用法相当于名词或形容词。数词分为_和_两种。考点1：基数词:表示_的词.1、基数词的构成巧记：基数词不难记，12以内词各异，13数到19去，teen莫丢弃，20、30到90，尾随ty是整十，若是说到几十几，中有“-”要强记，遇到整百要警惕。(1)1-12：_(2)13-19: (词尾加-teen)_(3)20,30,40,50,60,70,80,90(逢十词尾加-ty):_(4)21-99:在十位与个位之间加_符构成。如：21_ 99_(5)101-999:先说几百，再加and,再加末尾两位数或个位数。如：101- _ 238-_(6)1 000以上的数；先将数字从右往左数，每三位数用一
3、个逗号隔开，从右往左第一个逗号表示_读 thousand, 第二个逗号表示_读million,第三个逗号表示_读 billion. 如：18，657，421_(7)英语吕表示确数的方法为“基数词+计数单位的单数（hundred, thousand, million, billion）+名词复数”；表示概数的方法为“计数单位的复数（hundreds, thousands，millions, billions）+of+名词复数”，其前不能有具体的数词，但是可以有表示抽象概念的词 some, a few, many, several 等。如：There are _ _ workers in the

9、 Thirtieth(第三十)。表示几十几的基数词，只把_变成序数词即可：twenty-fifth（第二十五）。巧记：基变序有规律，词尾多加-th， 一二三特殊记，词尾字母tdd，八减t,九去e，f来把ve替， 遇到整十来结尾，一定将y变ie，若是碰到几十几，只变个位就可以。注意：序数词的简写构成：_：写出下列序数词的简写first_ second_ third_ fourth_ seventeenth_ twentieth_2.序数词的用法（1表示顺序。序数词表示顺序时，其前要加定冠词the，其后接单数名词。如：_ _ _ is very beautiful. 第二幅画很漂亮。_ _ _ c
