序数词与冠词a

序数词前一般要加定冠词,但是在某些场合,序数词前可不用定冠词或省去定冠词。 1.表示依次递增的新的序数词

时,序数词前面不用定冠词the,而用不定冠词a或an。这时表示的是“再一,又一”的意思。与这样的不定冠词连用

时,序数词表示“顺序”的语气就变弱了。a cond and a third were fixed.第一根横梁摆完以后,第二根、第三根横

梁也照此摆放。 I have called on him a third time, but l haven’t en him yet. I really must buy a cond pair of

shoes. Was there a fourth person at the meeting who held different ideas? 再如：

Plea try it a cond time. 再试一试。She could not go through that a cond time. He’s getting married a third time.

A cond swan flew down. Then a third and a fourth. 又一只天鹅飞了下来，接着是第三只，第四只。

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.

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!
