    序数词的基本用法
    1.序数词主要用作定语,前面一般要加定冠词(或物主代词):
    Tom is their second son.
    They celebrated the 10th anniversary of the founding of the republic.
    I will never give up,not even on the 1,000th or 10,000th try.
    2.有时前面可以加一个不定冠词来表示“再一”,“又一”这样的意思:
    We‘ll have to do it a second time.
    Shall I ask him a third time?
    When I sat down,a fourth man rose to speak.
    3.First,second 等有时可用来表示“第一个人(批)”“第二个人”等:
    She was among the first to come and settle in Dujiashan.
    You will be the second to speak.
    4.如果数字较长,序数词总避免使用,而且读的方法也常常简化:
    第201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
    南京路1490号:1490 Nanjing Road
    电话号码55――2347:telephone number :55—2347
    5. 在谈编了号的东西时,我们可以用基数词表示顺序:
    the first part——part one
    the third squad——squad three
    the twenty-third section——section twenty-three
