数词
数词主要包括基数词、序数词和分数词。基数词是表示数目多少的数词，序数词是表示先后顺序的数词。分数词由基数词和序数词构成。
一、基数词
1. dozen, score, hundred, thousand, million, billion等前有具体数字或several, a few等修饰时，一般用单数；它们的复数形式常后接of短语，表示不确切数目。如：
I make nine hundred dollars a week.
I must have mentioned him dozens of times in my letters.
2. 表示年岁时，用“in one’s +逢十的基数词的复数”，如in her fifties。
3. 表示年代时，用“in the +逢十的基数词的复数”。基数词的复数若用阿拉伯数字表示，可直接加s，也可加’s，如in the 1950s / 1950’s。
二、序数词
1. 序数词前通常要加定冠词the或形容词性物主代词，如the third floor, my first visit to New York。
2. 序数词前也可加不定冠词，表示“再一个，又一次”。如：
You really ought to make the most of the opportunity, because you won’t get a second chance.
三、分数词
1. 分子用基数词表示，分母用序数词表示；除分子为1的情况外，序数词都要用复数形式。
如：1/3 one third 2/5 two fifths
2. “分数/百分数+ of +名词/代词”作主语时，谓语动词的数与名词或代词的数保持一致。如：
One third of these jobs are held by women.
About 50 percent of his work is to design programmes.
四、常见考点
高考对数词的考查主要集中在年龄表达法、年代表达法、序数词前加冠词及数词作主语时的主谓一致等。
