高中英语课外辅导:数词难点揭秘

高中英语课外辅导: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; theB. the 90s; /
  C. 90s; their D. the 90s; their
  析。 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 threeB. twos and three
  C. two and threes
  D. twos and threes
  析。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. eightiesB. eighty C. the eightyD. the eighties
  析。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 twiceB. twice muchC. twice much asD. twice as much
  析。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。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。不少考生对分数构成及其用法特点缺乏了解,容易造成失分。
  例3:Can’t you see this map is _______ small as that one?
  A. half asB. as halfC. two-ninth asD. two as
  析:A。 A是B…的一半可表达为:A is half as...as B。但如果记不住这一结构,在极易混淆的备选答案前考生难免莫衷一是。
  例4ook, this bridge is only ________ that one.
  A. as long as four-fifthsB. four-fifths as long as
  C. as four-fifths as longD. as four-fifths long as
  析:B。A是B…的几分之几可表达为:A is +分数+as…as B。这种试题的备选答案形式相似,混淆度高,如果句型记忆不牢极易造成失分。
  应对方法:熟悉分数、百分数、半数、倍数的表达方式和A是B的几分之几/百分之几/一半/几倍的表达方式,并增强其使用意识。
博学多彩,阳光100分!!
