AEIS考试之中的AEIS写作是对考生的综合能力的考察,词汇、语言组织能力、逻辑能力等等,所以作文一直是招生官非常注重的部分,小编就为大家讲解基数词与序数词的用法!
基数词的用法
基数词在句中可用作下列句子成分:
1)主语
Two plus nine is eleven.二加九等于十一。
Four times six is twenty-four. 四乘六得二十四。
Three of them went to college last year.他们当中去年有三人上大学了。
(如说the three of them,意思则是"他们三个人")
2)宾语
Give me two.给我两个。
3)定语
There are nineteen students in our class.我们班有十九个同学。
My uncle bought two hand tractors recently.我叔叔最近买了两台手扶拖拉机。
(注)hundred(百),thousand(千)和million(百万)作定语用时一律不用复数;作名词用(后面多跟of短语)时则用复数。如:
Our country has a population of l,200 million people.我国有十二亿人口。
There are three thousand students in the university.这所大学有三千学生。
Rice has been cultivated in the East for thousands of years.水稻在东方已经种植了几千年。
Maize is the most important food crop for millions of people in the world.玉米是全世界千百万人最主要的粮食。
4)表语

序数词语法:
1-99的基本的序数词
序数词 缩写式 汉译
first [fE:st] lst 第一
second [5sekEnd] 2nd 第 二
third [We:d] 3rd 第三
fouth [fC:W] 4th 第四
fifth[fifW] 5th 第五
sixth[siksW] 6th 第六
seventh[5sevenW] 7th 第七

ninth[nainW] 9th 第九
tenth[tenW] 10th 第十

thirteenth 13th 第十三
nineteenth 19th 第十九
twentieth 20th 第二十
fortieth 40th 第四十
fifty-first 51st 第五十一
sixty-second 62nd 第六十二
说明:
1)英语序数词1-19除第一(first),第二(second),第三(third)有特殊形式外,其余均由基数词后加-th [W]构成。
2)有几个序数词加 -th 时拼法不规则,它们是:fifth,eighth,ninth,twelfth。
3)十位整数的序数词的构成方法是:先将十位整数基数词的词尾 -ty 中的y变成i,然后加-eth [iW]。
4)基数词"几十几"变成序数词时,仅将个位数变成序数词,十位数不变。如twenty-one变成twenty-first。
5)序数词的缩写形式,由阿拉伯数码后加上序数词的最后两个字母构成。如:1st,2nd,3rd,4th,31st,82nd,93rd,94th等。

[注]序数词前面常用定冠词the。

1/2 one half [hB:f]; 1/3 one-third; 2/3 two-thirds;
1/4 one-fourth或 one quarter [5kwC:tE]; 3/4 three-fourths或 three quarters; 2 3/5 two and three-fifths.
