中考英语 数词复习(1)
中考及高考英语知识重点复习专题(数词)
中考及高考英语知识重点复习专题（数词）中高考对数词的考查常常出现在听力、完形填空、语法填空和短文改错题型中。
数词部分主要考查：①基数词的用法②序数词的用法③倍数的表示方法听力理解对数词的考查主要集中在对各种号码、序列等表述。
语法填空对名词数词的考查仍然会成为高考的重点，主要集中在给出词根进行词类转化，根据习惯用法或固定短语确定名词的复数形式等。
【名师指导】1．注意数词的基本拼写方法从近年中高考试题看，中高考语法填空对数词的考查离不开具体的语境，在语境中考查数词的相关知识。
做题时，既要全面、整体地看题干，还要注意分析句子成分，并根据提示词来确定名词的相关考点。
通常，涉及名词考点的试题包括：(1）根据语境判断名词的单复数；(2）提示词是形容词、动词等此类，根据句子成分和词缀知识加上相应的后缀变成名词；(3）名词的固定搭配；(4）名词的所有格及名词的其他相关知识2．关注常见的号码及序列等的表述语法填空对名词的考查涉及名词各方面的知识，解题时要注意首先根据提示信息确定考点，试题是考查名词的词类转换，还是考查复数名词、名词的所有格，还是考查主谓一致、名词的固定搭配等，确定了考点之后，再结合其他相关知识来做出正确解答。
3．熟悉各种比较级倍数的表达方式中高考对名词的考查注重基础，我们在平时的复习中要打好基础，掌握足够的考纲词汇，并熟知其常见搭配和用法，并注意熟练掌握常用的名词词缀知识。
4、分类：数词有基数词和序数词两种。
英语的数词可以作句子的主语、宾语、表语和定语。
5、基数词：表示数目的词叫基数词。
6、序数词：表示顺序的数词叫序数词。
数字1-100基数词和序数词的对照100以上的基数词规则如下：108 → one hundred and eight ,146 → one hundred and forty - six ,500 → five hundred（500百）,1,000 → one ( a ) thousand（1千）,1,001→ one thousan and one ,1,813 →one thousand eight hundred and thirteen .10,000→ ten thousand（1万）,100,000→ one hundred thousand （10万）,1,000,000 one milion（百万）,10,000,000→ ten million（千万）,100,000,000 →one hundred million（亿）,900,000,000 →nine hundred million（9亿）1,000,000,000 a milliard（十亿）one milliard(美作:a billion, one billion)1,050,000,000 one billion and fifty million10,000,000,000 ten billion（百亿）200,000,000,000 two hundred billion（200亿）1,000,000,000,000 one thousand billion（千亿）(美作:a trillion, one trillion)注意：(1）百位与十位之间要加and; 十万位和万位，亿位和千万位之间通常也要加and。

9．C
【解析】
试题分析：句意：上周，在我们学校有两百名学生被采访。他们中的大多数认为学生应该给更多的时间去发展他们自己的兴趣。分析：two hundred表精确数字, two hundred students ; two hundred of后是加范围之类，
two hundred of the students; hundreds of表示约数,数以百计的故选C
2．B
【解析】
句意：我们学校近五分之三的学生是90后。考查分数的表达方法。在英语中关于分数的表达方法，是用基数词作分子，序数词作分母，当分子大于一时，分母后面要加s，所以五分之三的正确表达为：three fifths；结合选项可知B选项符合题意，其它选项均不正确，故答案选B。

(序数词构成规律)
基变序,有规律, 一、二、三，特殊记，面目全非要注意，
加th从4起， 八少“t”，九去“e”， “ve”要用“f”替，(five, twelve) 见“y”变成“i”和“e”，词尾加上“th”， (twenty, thirty,……ninety) 若是遇到几十几，只变个位就可以。
序数词缩写记清楚,数字后跟两字母。

基数词的用法
1、表示具体数目,hundred, thousand, million不用复数
表示不确定数目,用复数。即hundreds of(数百), thousands of(数千), millions of(数百万)+ 名词复数, 可以用many/several修饰，但不能与具体数目连用。
