高考英语数词考点归纳
1.
基数词和序数词的基本用法数词分基序数和序数词两类。基数词表示数目，序数词表示序数。序数词一般由基数词后加-th构成，且前通常要用定冠词the。 如： (上海卷)
A. The hundredth B. The hundred C. Hundredth D. A hundredth
【分析】答案选A。由单数名词cave及单数谓语动词is可知，是用序数词，排除B；序数词前通常用the，排除C和D。 2. 年龄表达法
①表示某人几岁的确切年龄，用“基数词＋years old”或“基数词＋of age”或者“at the age of＋基数词”，也可直接用基数词。 如：He looked quite healthy though he was
cave that George has discovered in his lifetime is near the Alps.
. (上海卷)
A. in seventy B. in his seventy C. at seventies D. at the age of seventy【分析】答案选D。at the age of seventy =at seventy =seventy =seventy years old = seventy years of age(在70岁时)。
②表示某人几十多岁这样的约略年龄，用“in one’s + 逢十的基数词的复数(如tens, twenties, thirties等)”来表达。
如： The hero of the story is an artist in his
. (全国卷) D. thirties
A. Thirtieth B. thirty C. thirty’s
【分析】答案选D。in his thirties在他30多岁时。 3. 年代表达法表示在某个世纪的几十年代，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：It is not rare in
that people in
fifties are going to
university for further education. A.
90s; the B. the 90s; / C. 90s; their D. the 90s; their
【分析】答案选D。表示年代时，基数词前一定要用the，排除A和C；表示某人几十多岁， 基数词前一定要用形容词性物主代词，排除B。
4. hundred, thousand和million的用法在hundred, thousand, million,
billion等的前面有基数词或several时，只能用单数形式；注意这类词前不能与many连用 ，若表示不确定数目的数百、数千、数百万等时，就一定要在它们的复数形式，还要加上

of了。如： day. (上海春)
people in the world are sending information by E-mail every
A. Several million B. Many millions C. Several millions D. Many million 【分析】答案选A。million前有several时，只能用单数形式在名词前作定语。请比较：H e has millions of books. (他有许多许多书。) 5. dozen, score的用法dozen, score的用法与hundred,
thousand等的用法相似。前面有基数词时，只能用单数作定语；若表示“几十”“许多” 时，用复数加of。 如：1. Mr. Smith (上海卷)
A. asked; dozen B. suggested; dozens of C. had; dozen D. persuaded; dozens【分析】答案选A。前有several时，
dozen只能用单数，排除B和D；根据句型搭配，可说ask sb. to do sth., 但却说have sb. do sth., 排除C。
2. Shortly after the accident, order. (全国卷)
A. dozens of B. dozens C. dozen of D. dozen
【分析】答案选A。前面无基数词，表示“许多，几十”时，用复数加of。注：①score用法略有不同，与数词连用时，也加of。如two score of eggs (40个蛋)。②有时单数形式的dozen, score, hundred,
million等前面有数词，后面也有of，此时的of表示的是部分与整体的关系，其后一定是t hem, us之类的人称代词或者有the, these, your之类的限定词。 如I want to buy three dozen of the eggs. (我想买其中的三打蛋。) 6.
分数表达法分子用基数词，分母用序数词，当分子大于一时，分母的序数词要用复数。表 示几分之几的人或物时，要用介词of。若作主语，谓语动词与of后的名词一致。 如：1.
of the land in that district
covered with trees and
police were sent to the spot to keep
me to buy several
eggs for the dinner.
grass. (上海卷) A.
Two fifth; is B. Two fifth; are C. Two fifths; is D. Two fifths; are
【分析】答案选C。分子two大于一，分母fifth要用复数，排除A和B；of后的名词land是单数，谓语动词也用单数，排除D。 2. China is

如：Forty percent of the students wear glasses. 百分之四十的学生戴眼镜。
8.
“基数词+名词”作定语“基数词+名词(+形容词)”作定语，通常有以下两种形式：“不定冠词+基数词+连字符号+单数名词+(连字符+形容词)+名词”； “基数词+名词的所有格+名词”。
如a ten-minute walk=ten minutes’walk （步行10分钟的路程) a 50-meter-wide road (一条50米宽的公路) an eight-year-old boy =a boy of 8
