  二、序数词“三注意”。

  一)序数词的构成及基本用法。

  注意:序数词一般以与之相应的基数词后加-th 构成,少数几个需特别记忆。为方便大家记忆,请看下面口诀。

  基变序,有规律,first, second, third要牢记; 其它变化有公式,基数词尾加-th; eight去t , nine去e; 从twenty, thirty到ninety, 需变y为ie; five和twelve, 需将ve变f; 若是遇到“几十几”,只变个位就可以。

  另外,注意:序数词前要加定冠词the, 在句中作定语放在所修饰的名词前。如:December is the twelfth month of the year. 十二月是一年中的第12个月。

  挑战中考:

  A. twenty; twentieth-first B. twenty; twenty-first C. twentieth; twenty-first D. twenty; twenty-one (05贵州黔西南州)

  二)序数词与冠词a/an连用。

  注意:序数词前加不定冠词a/an, 表示“又一”、“再一”的意思。如:Please try it a second time. 请再试一试。

  但基数词与more连用,并放在more前,表示“另外有”、“还有”的意思。如:I’ll take one more (=another) pencil. 我还要一支铅笔。We ’ve just started! There were twenty more trees to be planted! 我们才刚开始呢!还有20棵树要栽呢!
