  数词的基本用法
  (一)基数词的基本用法

  数词作主语,谓语动词用单数。

  3.宾语或介词宾语

  Five plus seven is twelve.
  5.同位语

  6.基数词+单数名词+形容词构成合成形容词。如:一个五岁的男孩a five-year-old boy;一座800米长的桥an 800-metre-long bridge;女子400米接力girls‘400-metre relay race.
  7.句型:主语+is +about(大约)/ over =more than(超过)/nearly(接近)+具体数词+metre(s)/kilometre(s)/kilo(s)long / high /tall /deep /away等。如:长江长6300公里。
  The Changjiang River is 6,300 kilometres long.
  8.表示“……十”的数词的复数形式可以用来表示人的岁数或年代:
  He is in his early thirties.
  He died still in his forties.

  (二)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?

  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
