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。
2023年中考英语二轮复习专项讲义——数词一、基数词:表示数目的词叫基数词。
(一)基数词的表示方法1、最基本的基数词: 见书中表格2、hundred, thousand, million, billion, dozen, score 这些词前面如果有表示具体数字的词,它们末尾不能加“s”且不能与of连用;反之则末尾需加“s”,与of连用。
three hundred people; thousands of people; three thousand of the people(二)基数词的用法1、用基数词表示编号。
Today we are going to study Lesson Five. 今天我们要学习第五课。
He lives in Room 801. 他住在801房间。
2、表示大几倍或者小多少用基数词。
This room is three times bigger than that one. 这个房间比那个房间大三倍。
3、“数词+名词(+形容词)”构成复合形容词作定语,其中名词用单数形式,数词与名词及形容词之间用连字符“-”。
A twenty-one-year-old girl is behind me. 一位21岁的女孩在我身后。
4、两组与数词有关的介词短语:(1)in+定冠词the+整十基数词的复数形式,表示年代。
In the 1870s在19世纪70年代(2)in+物主代词+整十基数词的复数形式,表示某人的大约年龄。
in one’s thirties在某人30多岁的时候有时在物主代词后面可加上形容词early或late使其含义更确切一些。
The young man is in his early thirties. 这个年轻人刚30岁出头。
注意:“十几岁”要用in one’s teens; 二、序数词:表示数目顺序的词叫序数词。
(一)序数词的构成:写法口诀:1.2.3特殊记,th从4加起,两个ve ,f替,8去t 9去e,ty变成tie,后加th莫迟疑,若是几十几,只变个位就可以。
语法专项突破数词考试要求:中考关于数词的考查要求是:基数词表示数目和号码的用法;基数词表示年级、班级、房间和编号的用法;hundred,thousand,million和billion的用法;序数词表示次序的用法;分数的表达方式及用法;定冠词the和序数词连用知识点等。

(注意20,30,40,50,80拼写的特殊变化。
)(4) 21-29的基数词:由十位数20的单词形式twenty加个位数1-9构成。
中间用连字符。
即:21-twenty-one,22-twenty-two,23-twenty-three,24-twenty-four,25-twenty-five,26-twenty-six,27-twenty-seven,28-twenty-eight,29-twenty-nine。
其他的十位数照此类推。

例如:127-one hundred and twenty-seven。
(6) 千位数是由1-9加thousand构成,后面的百位数、十位数和个位数与前面的构成方法一样。
