数词虽然高考不是每年都出,但是数词被考查的比率并不低,这应该引起我们的重视。本文仅就有关的高考题目,结合数词本身的特点,作一分类解析,希望能对同学 考点一:对基数词的考查: 点拨: 1.考查其作主语时的主谓一致,具体数目与笼统数目的构成,例如:hundreds of , a hundred , a second 等。 2.用数词表示度量衡时,常和名词所有格出现。 3.基数词表示年代,年龄的用法。 4.用数词构成的短语可作形容词,表示“再几,又几”。 【经典考例】 ______ people in the world are sending information by E-mail every day. A. Several million B. Many millions C. Several millions D. Many million 解析:答案为A。million 前有具体数字或several等词时,要用单数形式。many 一般不与million 等数词连用,表示“数百万”,英语为millions of。 A. 90s ; the B. the 90s ; / C. 90s ; their D. the 90s ; their 考点二:对序数词的考查: 点拨: 1.序数词修饰名词时,一般前面有定冠词the ,有时也用于不定冠词a,表示“再一,又一”。 2.表示顺序的编号事物,一般可有两种:第一种,定冠词+序数词+事物名称;第二种:事物名称 【经典考例】 _______cave that George has discovered in his lifetime is near the Alps. A. The hundredth B. the hundred C. Hundredth D. A hundredth 解析:答案为A。序数词修饰名词时,一般前面必须有定冠词the,表示序列。 考点三、对分数的考查: 点拨: 分数是由基数词(分子)和序数词(分母)构成,当分子大于1时,序数词分母必须用复数形式。 【经典考例】 The husband gave his wife ____ every month in order to please her. A. all half his income B. his half all income C. half his all income D. all his half income 解析:答案为A。all his income 他收入的一半。为了使妻子高兴,丈夫每月把他收入的一半给了妻子。 【经典考例】 ______ of the land in that district ______covered with trees and grass.
