数词难点揭秘一、数词竟然有复数,平时学习不注意 难点介绍: 对数词的掌握不少同学建立在基数词、序数词及其转换上,很少有人会想到数词的复数形式,结果造成高考中的失分。 题例分析: 例 1:It is 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 析:D。 第一空表"在 90 年代",应用 in the 90s 短语;第二空表"在他们五十多岁时",应用 in their fifties 短语,但不少同学不了解数词的复数形式,结果只能乱选一气。 例 2:All of the students came into the classroom by ________. A. two and three B. twos and three C. two and threes D. twos and threes 析:D。三三两两应表达为 by twos and threes,但有些同学因对数词的复数形式缺乏了解而造成解题错误。 例 3:It is said that this terrible matter happened in ________. A. eighties B. eighty C. t he eighty D. the eighties 析:D。in the eighties 表"在八十年代",符合题意,但有些同学因对这种语法现象知之甚少而造成解题错误。 应对方法:重视 数词的复数形式,熟悉数词的复数形式,如 by twos and threes 三三两两,in the eighties 在八十年代;in his forties 在他四十多岁时;in the 1980's/1980s 在二十世纪八十年代。 二、特殊数词记不住,考试难免会出错 难点介绍: 不少同学对基数词、序数词非 常熟悉,但对分数、百分数、半数、倍数等特殊数词形式不太了解,即使有所接触也因其形式复杂而失分。 例 1:It is reported that the United States uses ________ energy as the whole of Europe.
