英语四级听力题型解析：等值转换题

四级听力等值转换题

这种题型相对来说比较令考生头疼，特点是因为它的答案无法在原文中直接找到，必须通过换算的方式计算出结果，而并非运用原文中的线索直接加减乘除，所以你一定要对英语中的代用词相当的敏感，以下为英语中常用到的代用词，务必倒背如流。

① 时间的代用词
quarter 一刻钟、四分之一、季度 a dozen 一打、十二个
score 二十 monthly 一月一次
daily 一日一次 weekly 每周一次
fortnight 两星期 decade 十年
century 世纪、百年 millennium 千年

② 倍数、货币的代用词
double、twice 两倍 fivefold 五倍
half 一半 a quarter 25美分
a dime 10美分 a nickel 5美分

【例1】

W: We have worked for a fortnight. And really need a break.
M: How about seeing a play? I hear “Spiderman” is on at the National Theatre.
Q: How long have they been working?
A) Four nights B) Forty nights
C) Fourteen days D) Four days

【解析】 这题当中应区分fortnight和four nights之间的发音。fortnight代表两个星期，也就是十四天，所以C为正确答案。

【例2】

M: Lisa, you know that Tom was late twice this week.
W: It’s ok, the class is so boring, I was late three times that often and Mark was late six times.
Q: How many times was Tom late?
A) 1 B) 2 C) 3 D) 6

【解析】 Twice 是英语数字2的代用词，分清问的是Tom，答案为B。
