數(shù)詞主要包括基數(shù)詞、序數(shù)詞和分數(shù)詞。基數(shù)詞是表示數(shù)目多少的數(shù)詞，序數(shù)詞是表示先后順序的數(shù)詞。分數(shù)詞由基數(shù)詞和序數(shù)詞構(gòu)成。 一、基數(shù)詞

　　1. hundred, thousand, million, billion, dozen, score等前有具體數(shù)字或several, a few等修飾時，一般不用復(fù)數(shù)；在表示不確切數(shù)目時，可用復(fù)數(shù)。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. 表示年歲時，用“in one’s +逢十的基數(shù)詞的復(fù)數(shù)”。如：in his forties。

　　3. 表示年代時，用“in the +逢十的基數(shù)詞的復(fù)數(shù)”。基數(shù)詞的復(fù)數(shù)若用阿拉伯?dāng)?shù)字表示，可直接加s，也可加’s。如：in the 1950’s / 1950s。 二、序數(shù)詞

　　1. 序數(shù)詞前通常要加定冠詞the或與物主代詞一起使用，在句中可作主語、賓語、定語和表語等。

　　2. 序數(shù)詞前也可加不定冠詞，表示“再一，又一”。如：a third time, a third and a fourth等。 三、分數(shù)詞

　　1. 分數(shù)詞是由基數(shù)詞和序數(shù)詞構(gòu)成，分子用基數(shù)詞表示，分母用序數(shù)詞表示；除了分子為1的情況下，序數(shù)詞都要用復(fù)數(shù)形式。如：1/3 one third；3/5 three fifths。

　　2. “分數(shù)/百分數(shù)+ of +名詞/代詞”作主語時，謂語動詞的數(shù)與名詞或代詞的數(shù)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、常見考點

　　高考對數(shù)詞的考查主要集中在年齡表達法、年代表達法、序數(shù)詞前加冠詞及數(shù)詞作主語時的主謂一致等。 【考例】One-third of the country _______ covered with trees and the majority of the citizens _____ black people.?

　　A. is; are ?????? ????????????????? B. is; is C. are; are ? ? ? ? ? ? ? ? ? ? ? D. are; is
