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. hundred, thousand, million, billion, dozen, score等前有具体数字或several, a few等修饰时,一般不用复数;在表示不确切数目时,可用复数。如:
Several million people in the world are using this brand of toothpaste every day.
My teacher went to the bookstore and bought dozens of books.
2. 表示年岁时,用“in one’s +逢十的基数词的复数”。如:in his forties。
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 1950’s / 1950s。 二、序数词
1. 序数词前通常要加定冠词the或与物主代词一起使用,在句中可作主语、宾语、定语和表语等。
2. 序数词前也可加不定冠词,表示“再一,又一”。如:a third time, a third and a fourth等。 三、分数词
1. 分数词是由基数词和序数词构成,分子用基数词表示,分母用序数词表示;除了分子为1的情况下,序数词都要用复数形式。如:1/3 one third;3/5 three 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: Two-thirds of her spare time is spent on housework. 80 percent of the houses were damaged in the big earthquake. 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。 【考例】One-third of the country _______ covered with trees and the majority of the citizens _____ black people.
