基数词和序数词

（时间：60分钟，满分：100分）

基数词的用法

(1)当hundred, thousand, million, billion等和of连用，表示粗略的数目时,须用复数。如hundreds of people数以百计的人;

但如果hundred, thousand, million, billion等词前有具体数词或several时，须用单数six hundred people 600人.

(2)表示“几十年代”或“几十岁”时，用逢十的基数词的复数。如：

in the thirties在30年代          in his fifties在他50多岁时

(3)与基数词合成的复合形容词，其中的名词用单数。如：

a three-month-old baby三个月大的婴儿       a five-year plan一个五年计划

序数词

序数词一般以与之相应的基数词加词尾-th构成，但要注意一些特殊形式。

（一）阿拉伯数字基数词序数词序数词缩略式

（二）特别提示

1、以y结尾的基数词构成序数词时，先把y变为ie, 再加-th。

2、几十几及以上的序数词，其中十位数或百位数、千位数等用基数词，只有个位数才用序数词。如： 128th: one hundred and twenty-eighth      752nd: seven hundred and fifty-second
