[ 规则感悟 ] ①数词的基本形式为基数词。②表示数词的顺序往往用序数词。大部分是在基
数词的基础上加 -th 。以 -y 结尾的基数词变序数词,把 -y 变成 -ie 再加 -th 。③“ in the +逢十的
基数词的复数”表示“在某个世纪几十年代”。“ in one ’ s +逢十的基数词的复数”表示
“在某人几十多岁时”。④具体数字+ dozen/score/hundred/thousand/million 等词时,后面直
接加名词复数;表示笼统数目时,用 dozens/scores/hundreds/thousands/millions of +名词复数。
⑤分数表达:分子用基数词,分母用序数词。当分子大于 1 时,分母序数词加 -s ,如: 1/3 :
one third,2/3 : two thirds 。
1 . 易错基数词
thirteen 十三 fourteen 十四 fifteen 十五
eighteen 十八 nineteen 十九 twenty 二十
thirty 三十 forty 四十 fifty 五十 ninety 九十
2 . 易错序数词
first 第一 second 第二 third 第三 fourth 第四
fifth 第五 eighth 第八 ninth 第九 eleventh 第十一 twelfth 第十二
3 . 序数词的使用
(1) 序数词在句中主要作定语,一般情况下序数词前要加定冠词。
This is the second intangible cultural heritage block in Guangzhou.
这是广州第二个非物质文化遗产街区。
(2) 序数词前有时加不定冠词,表示“又一、再一”,相当于 another 。
Would you like a second cup of tea?
你还想再来一杯茶吗?
(3) 有时序数词作状语,不加冠词。
He came out first in the contest.
他在比赛中获得第一名。
