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。

数词易错清单1. 确数和约数(1)当我们说“几百”、“几千”这样一些确数时,“百”、“千”是不能用复数形式的。
结构是:数词+hundred/thousand/million/billion+名词复数如:five hundred五百;three thousand三千;two million两百万;six billion六十亿。
(2)当hundred,thousand,million加上s后,它们就成了概数,表示“数百”、“数千”、“数百万”等概念。
而且通常接of,表示“成百的”,“数以千计的”,“成千上万的”,“亿万的”等。
结构是:hundreds/thousands/millions/billions+of+名词复数。
如:hundreds of new tall buildings数以百计的新高楼;thousands of students数以千计的学生;millions of people数以百万计的人。
2. 数词和冠词的关系(1)一般情况下,序数词前要加定冠词the,但基数词前不加冠词。
如:He failed in the first try. 他第一次尝试失败了。
My number is forty-nine.我的号码是49。
(2)a/an+序数词,表示“又一、再一”。
如:The monkey ate a second banana.这只小猴又吃了一根香蕉。
(3)of the+基数词,表示“范围”。
如:You can choose a toy of the two as a birthday present.你可以在这两个玩具中选一个作为生日礼物。
3. “数词+more”与“another+数词”(1) 表“另外的”接复数名词,如与具体数词连用,则置于数词之后,但与定冠词the连用时,other要放在数词前。
如:Mr Smith asked me to fetch another three CDs.史密斯先生让我再拿三张CD。

如first, second, third, fortieth等。
数词的用法要注意一下几点:1、基数词和序数词的拼写形式。
主要掌握1-12及20、21等的序数词的形式,其它序数词都是在基数词末尾加-th,是有规律可循的。
one—first six—sixth eleven—eleventhtwo—second seven—seventh twelve—twelfththree—third eight—eighth thirteen—thirteenthfour—fourth nine—ninth twenty—twentiethfive—fifth ten—tenth twenty-one—twenty-first另外,序数词的缩略形式是由阿拉伯数字加序数词的最后两个字母构成。

表示时刻有两种说法:1) 先说分钟,后说钟点。
几点过几分,分钟不超过三十分钟时用past。
例如:It’s five past eight now. 现在是八点(过)五分。
几点差几分或差几分几点,差的分钟数不超过二十九分钟时,用to。
例如:It’s twenty-nine to eight. 八点差二十九分。
It’s a quarter to eight. 差一刻八点。
2)先说钟点,后说分钟。
在日常生活中,为了简便,常用这种说法。
例如:It’s eight thirty.八点三十分。
3.年、月、日表达法。
1)年份用基数词表示,一般写为阿拉伯数字,读时可以以hundred为单位,也可以以世纪、年代为单位分别来读。

1.1-12的表述1-12各有各的形式,即one,two,three,four,five,six,seven,eight,nine,ten,eleven,twelve。
2.13-19的表述13-19的数字皆以-teen[ti:n]结尾,其中,fourteen,sixteen,seventeen,eighteen和nineteen分别由four,six,seven,eight,nine加后缀-teen变成的,eighteen 中只保留一个t。
thirteen,fifteen分别由three和five转花而来。
3.20-90数字的表达20-90的数字皆以-ty结尾,其中,sixty,seventy,eighty,ninety 分别由six,seven,eight和nine加后缀—ty构成,eighty中只保留一个t。
其他同上。
4.20-99之间的数字的表达20-99之间的数词须在十位和个位之间加连字符“-”,如twenty-five。
百位以上的数字的表达以及读在表达百位以上的数字时,必须在百位,十位和个位之间加and,在读音时也应读上and,如:104可表达为one hundred and four,486读作four hundred and eighty-six。
“万”的表达.英语中没有万和亿单词,只有百(hundred),千(thousand),百万(million),十亿(billion)。
英语中表示“万”时,用10千。
如:forty thousand四万。
表示“亿”时需用百万来表示。
