  注意:“基数词+名词(+形容词)”构成的复合形容词作定语时,其中的名词用单数形式。如:two-week holiday 两周的假 ; an eighteen-metre-wide street 一条18米宽的街道

  但注意它与名词所有格形式作定语的区别。如:How far is it from your home to your school? It’s about ten minutes’ walk. 从你家到到学校多远?大约十分钟路程。

  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。

  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!

  挑战中考:

  三)分数的表达法。
