tenth (10th) 第十 eleventh (11th) 第十一 twelfth (12th) 第十二 thirteenth (13th) 第十三 fourteenth (14th) 第十四 fifteenth (15th) 第十五 sixteenth (16th) 第十六 seventeenth (17th) 第十七 eighteenth (18th) 第十八 nineteenth (19th) 第十九
这一类序数词共有十六个。均在相应的基数词后面加上后缀-th构成。要注意其中fifth、eighth、ninth、twelth四个词的拼法。
3、第三类:
twentieth (20th) 第二十 thirtieth (30th) 第三十 fortieth (40th) 第四十 fiftieth (50th) 第五十 sixtieth (60th) 第六十 seventieth (70th) 第七十 eightieth (80th) 第八十 ninetieth (90th) 第九十
这一类全是十位整数的序数词,共八个。它们的构成方法是:先将相应的十位整数的基数词词尾-ty中的y改成i,然后在加上后缀-eth。
4、第四类:
thirty-first (31th) 第三十一

sixty-second (62nd) 第六十二 eighty-seventh (87th) 第八十七 ninety-eighth (98th) 第九十八
这类表示“第几十几”的序数词,跟表示“几十几”的基数词一样简单。在构成方法上均由基数词“几十几”变化而来,十位数不变,仅把个位上的基数词变成序数词就行了。

基数词及序数词重要用法
1. 基数词的用法
基数词用于表示事物的数量,在表示基数词时,要特别注意hundred, thousand, million, billion等几个词的用法:若其前用了基数词,则不论其面是否有of,都必须用单数形式(此时若带of则通常表示特定范围中的一部分);若泛指数百、数千、数百万等,则用 hundreds of, thousands of, millions of 等这样的结构。如:
Two hundred of the students are needed to plant trees this morning. 今天中午需要200个学生去植树。
Hundreds of people attended the famous director’s farewell concert. 好几百人出席了这位著名指挥家的告别音乐会。 Thousands upon thousands of English words come from foreign tongues. 成千上万英语单词来自外来语。 2. 基数词的复数用法
逢整“十”的基数词的复数形式可用于表示某人的大约年岁和世纪中的年代。如: The war broke out in the nineties. 这次战争爆发于90年代。
Karl Mark began to learn the Russian language in his fiftieth. 马克思五十多岁开始学俄语。 3. 序数词的用法
序数词用于表示事物的顺序,一般由与之相应的基数词加th构成(但有特殊形式需特别记忆);序数词主要用作定语,前面一般要加定冠词(或物主代词)。如:
Their second son is a doctor. 他们的二儿子是个博士。
The hundredth cave that George has discovered in his lifetime is near the Alps. 乔治一生中找到的第一百个山洞在阿尔卑斯山附近。
注:序数词前有时可用不定冠词,表示“每一,又一”。如: We’ll have to do it a second time. 我们将再做一遍。 基变序口诀 基变序,有规律 词尾加上-ed(fourth,sixth) 一、二、三,特殊例,
结尾字母t,d,d(first,second,third) 八去t,九去e,(eighth,ninth) ve要用 f替;(fifth,twelfth) ty将y改成i, th前面有个e。 若是碰到几十几, 前用基来后用序。
或记忆为:一、二、三,特殊记,词尾字母t,d,d 八加h,九减e,逢十改y为ie f要把ve替,还有th莫忘记
