序数词的构成 ①序数词多数由"基数词-th"构成，序数词前一般加定冠词the ②少数序数词构成属特殊情况 e.g. One-first two-second three-third five-fifth eight-eighth nine-ninth twelve-twelfth ③以y结尾的十位整数，先将y改为i，再加-eth e.g. thirty-thirtieth ④21以上的多位数，要将末位数改为序数词，前面其他位数仍用基数词 e.g. eighty-three-eighty-third nine hundred and sixty-two-nine hundred and sixty-second ⑤序数词的缩写形式由阿拉伯数字加序数词的后两个字母构成 e.g. first-1st second-2nd (责任编辑：admin) |
