来源 :中华考试网 2015-10-08

  表示“几点差几分”用介词to, 但分数须在半小时以上。例如:

  twenty to nine,

  five to eight,

  a quarter to ten

  表示“几点几分”还可直接用基数词。例如:

  seven fifteen,

  eleven thirty,

  nine twenty

  2. 序数词的用法

  (1)序数词主要用作定语,前面要加定冠词,例如:

  The first truck is carrying a foot baskets.

  John lives on the fifteenth floor.

  (2)序数词有时前面可加不定冠词来表示“再一”,“又一”这样的意思,例如:

  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)由几个序数词和基数词在拼写时不对应,很容易写错,应特别注意。它们是:one---first, two---second, three---third, five---fifth, eight---eighth, nine---ninth, twelve---twelfth。

  (4)表示年,月,日时, 年用基数词表示,日用序数词表示。例如:

  1949年十月一日读作: October (the) first, nineteen sixty

  2004年九月十日读作:September (the) tenth, two thousand and four

  (5)表示分数时,分子用基数词表示,分母用序数词表示。分子大于1时,分母加-s。例如:

  three fourths,

  one second,

  two fifths

  (6)序数词有时用缩写形式:

  first→1st second→2nd

  third→3rd fourth→4th

  twenty-second→22nd
