数词易错淸单1.确数和约数(1)当我们说“几百”、“几千”这样一些确数时，“百”、“千”是不能用复数形式的。

结构是：数词 +hundred/thousand/mi 11 ion/bi 11 ion+名词复数如：five hundied 五百；three thousand 三千；two ndllion 两百万；six b订lion 六十亿。

(2)当hundred, thousand, mi 11 ion加上s后，它们就成了概数，表示“数百”、“数千”、“数百万”等概念。

而且通常接of,表示“成百的”，“数以千计的”，“成千上万的”，“亿万的”等。

结构是：hundreds/thousands/mi 11 ions/bi 11 ions+of+名词复数。

如：hundreds of new tall buildings 数以百计的新高楼;thousands of students 数以千计的学生；mi llions of people数以百万计的人。

2.数词和冠词的关系(1)一般情况下，序数词前要加定冠词the,但基数词前不加冠词。

女口：He failed in the first try.他第一次尝试失败了。

My number is forty-nine.我的号码是 49o(2)a/an+序数词，表示“又一、再一”。

如：The monkey ate a second banana.这只小猴又吃了一根香蕉。

(3)of the+基数词，表示“范围”。

如：You can choose a toy of the two as a birthday present.你可以在这两个玩具中选一个作为生日礼物。

3."数词 +more v与“another'+数词”(1)表“另外的”接复数名词，如与具体数词连用，则置于数词之后，但与定冠词the连用时,other要放在数词前。

如:Mr Smith asked me to fetch another three CDs.史密斯先生让我再拿三张CD。
