英语中考数词考点（数词中考真题2011-2019）

数词

数词分为基数词和序数词。用于表示事物数目的词称为基数词，表示事物顺序的词称为序数词。

1.基数词(1000以内的基数词的读法)

(1)1-20：one，two，three，four，five，six，seven，eight，nine，ten，eleven，twelve，thirteen，fourteen，fifteen,sixteen，seventeen，eighteen，nineteen，twenty

2.基数词变序数词的方法：

(1)一般在基数词后加th

eg.four→fourth,thirteen→thirteenth

(2)不规则变化

one→first,two→second,three→third,five→fifth,eight→eighth,nine→ninth,twelve--~twelfth

(3)以y结尾的十位整数,变y为ie再加th

twenty→twentieth,forty→fortieth,ninety→ninetieth

(4)从二十一后的“几十几”直至“几百几十几”或“几千几百几十几”只将个位的基数词变为序数词。

twenty-first,twohundredandforty-fifth

口诀：

基变序，有规律;词尾要加th。

一二三，特殊记;词尾分别tdd。

八去t，九去e;ve则以f替。

ty则变作ti;后面还有一个e。

要是遇到几十几;只将个位变成序。

3.数词的应用：

A、时间：

a.整点：基数词+o’clock

eg.It’seighto’clocknow.

b.几点几分：

eg.3:25threetwenty-five

2.间接表达法：先分后小时

1)(<30分钟)用past ：分钟past 小时

eg.3:25twenty-five(minutes)pastthree

2)(>30分钟)用to：(60-分钟数)to(小时数+1)

eg.3:35twenty-five(minutes)tofour

3)30分钟=half15分钟=aquarter

eg.3:30threethirty=halfpastthree

3:15threefifteen=aquarterpastthree.

3:45threeforty-five=aquartertofour

B、日期表达法：月日，年(或日月年)

1949年10月1日:

eg.You’vedoneitthreetimes.Whynottryafourthtime?

E、分数的表达：分子(基数)、分母(序数)

eg.onethird三分之一twothirds三分之二

注意：1.分子超过1时，分母加s

2.含分数的短语作主语由分数后的词决定谓语
