2011高考英语二轮复习 数词难点揭秘教案

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. the 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。 题例分析: 例 1:It is reported that the United States uses ________ energy as the whole of Europe. A. as twice B. twice muchC. twice much as D. twice as much 析:D。该题考查倍数的表达方法,其结构为:A... times as 形容词/副词原级 as B,不少考生没记住这个结构,结果造成失分。 例 2:He did it ________ it took me. A. one-third a time B. one-third time C. the one-third time D. one-third the time 析:D。分数的表达方式为:先讲分子,再讲分母,分子用基数词,分母用序数词,分子大于 1 时分母用序数词的复数形式,中间加连字符号。分数应放在所修饰的名词前面。不少考生对...
