2.表示顺序的数词称为序数词.序数词一般以与之相应的基数词加词尾th构成.如: tenth.但下面这些基数词在变为序数词时.有特别的地方: ①one-first, two-second, three-third, five-fifth, eight-eighth, nine-ninth, twelve-twelfth. ②以-ty结尾的词.要先变y为i.再加-eth.例如: twenty-twentieth, forty-fortieth. ③以one, two, three, five, eight, nine收尾的多位数词.要照第一条办法变.例如: twenty-one-twenty-first, twenty-two-twenty-second, thirty-five-thirty-fifth, ninety-nine-ninety-ninth a hundred and fifty-three-hundred and fifty-third 序数词主要用作定语.前面要加定冠词.例如: This is the first public performance of the play. 这是该剧的首次公演. [注意]在谈到编号的东西时.通常用序数词.例如: the first part第一部分 the twenty-third section第二十三章 也可以用基数词来表示(这时名词要放在基数词之前.名词和基数词都要大写): the first part第一部分→Part One the twenty-third section第二十三章→Section Twenty-third 如果数字较长.序数词总避免使用.例如: 第201号房间:Room 201 第319面:Page 319 第一拖拉机厂:the Number I Tractor Works 第六号车厢:Carriage No.6 第七路公共汽车:Bus Number Seven 查看更多
