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:
1、Several million people in the world are using this brand of toothpaste every day.
2、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:
1、Two-thirds of her spare time is spent on housework.
2、80 percent of the houses were damaged in the big earthquake.。
