答案: B (选择C的同学要注意应用two months’; 选择D的同学要注意名词之间有 “- “ 后的组合词当作形容词来用, 因此就不用所有格形式了.)

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．

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．

3) 注意较为容易拼写错误的序数词及其缩写形式：one---first, two---second, three---third, five---fifth, eight---eighth, nine---ninth, twelve---twelfth。

缩写形式：first→1st 　　　　　second→2nd　　 third→3rd　　　　　　fourth→4th　　 twenty-second→22nd

4) 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

2、难点　

倍数表示法 主语+谓语+倍数(或分数)+ as + adj. + as I have three times as many as you.　我有你三倍那么多。 3、易错点

(主要体现在口语考试和听力题目中) 2)表示一个具体数字时，hundred, thousand, million, billion一律不用复数；在表示一个不确定数字时则用复数。例如：

There are three thousand students in our school.

After the war, thousands of people became homeless.

3)在一些表示"一排"或"一组"的词组里； 如：They arrived in twos and threes.　他们三三两两的到达了。 4)表示"几十岁"， 例如：He died still in his forties． 5)表示"年代"，用 in +the +数词复数；
