第三十一 thirty-first (31st) 第六十二 sixty-second (62nd) 第八十三 eighty-third (83rd) 第九十八 ninety-eighth (98th)
第十一 eleventh (11t h) 第十二 twelfth (12th) 第十三 thirteenth (13th) 第十四 fourteenth (14th) 第十五 fifteenth (15th)
sixteenth (16th) 第十六 seventeenth (17th) 第十七 eighteenth (18th) 第十八 nineteenth (19th) 第十九
3、第三类: 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。
第二十 twentieth (20th) 第三十 thirtieth (30th) 第四十 fortieth (40th) 第五十 fiftieth (50th)
第六十 sixtieth (60th) 第七十 seventieth (70th) 第八十 eightieth (80th) 第九十 ninetieth (90th)
4、第四类: 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。
2、第二类:“13-19”的基数词以teen结尾,除了thirteen和fifteen特别 点之外,它们后面都只加teen就可以了。 但要注意eighteen的拼法,eight本身 有t字母,因此只加een。

屏幕上呈现“厕所”二字,让学生尽快尽可能多地查阅它的表达方法,老师并 将知道的写在黑板上。 学生可能会说出washroom, water closet, restroom, ladies’ room(女厕所), women’s room (女厕所), men’s room(男厕所),public comfort station等。 之后老师再呈现出number one 在屏幕上,让学生猜其意思,也可以查字典。 老师可以告诉学生number one (小便)是在美国学生中广泛流行的说法。 随之老师呈现number two (大便)让学生猜意。再呈现go to fourth(上厕所), 说明这一说法源于19世纪英国剑桥大学的笑话,当时的学生早晨的常规活动是: 做礼拜,用早餐,吸烟,上厕所。这相当于three to get ready and four to go(前三件事做准备,第四件事上厕所)。
