11、#160;  5th-fifth12th-twelfth 整十的序数词的构成方法是（20-90）：先将十位数的基数词的词尾-ty 中的y 变为i, 然后加后缀-eth.20th  twentieth       30th   thirtieth40th  fortieth        50th   fiftieth 十位数的序数词，如包含1-9的个位数时，十位数用基数词，个位数用序数词，中间须有

13、二、三、特殊记，词尾字母t,d,d.(first, second, third)。 八减t九去e,（eighth, ninth）, f 来把ve替。（twelfth）. 单词ty作结尾，ty变成tie(twentieth). 若是碰到几十几，只变个位就可以。（twenty-first） 三、数词的运用：（一）、时间的表达法1. 表示整点用基数词+ oclock 也可省略，介词用at.6:00 six oclock (或six)       8:00 eight oclock (或eight)2. 用past 表示“几点几分”，但分数必
