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(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:
1.直接表达法:先小时后分
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)
年10月1日:

D、序数词与不定冠词(a;an)连用表“又一;再一”
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

2)Onethirdofthemilkismine.
