英語四級聽力題型解析04：等值轉(zhuǎn)換題
四級聽力等值轉(zhuǎn)換題?
這種題型相對來說比較令考生頭疼，特點是因為它的答案無法在原文中直接找到，必須通過換算的方式計算出結(jié)果，而并非運用原文中的線索直接加減乘除，所以你一定要對英語中的代用詞相當(dāng)?shù)拿舾?，以下為英語中常用到的代用詞，務(wù)必倒背如流。?
① 時間的代用詞?
quarter 一刻鐘、四分之一、季度 a dozen 一打、十二個?
score 二十 monthly 一月一次?
daily 一日一次 weekly 每周一次?
fortnight 兩星期 decade 十年?
century 世紀(jì)、百年 millennium 千年?
② 倍數(shù)、貨幣的代用詞?
double、twice 兩倍 fivefold 五倍?
half 一半 a quarter 25美分?
a dime 10美分 a nickel 5美分?

M: How about seeing a play? I hear “Spiderman” is on at the National Theatre.?
Q: How long have they been working??

C) Fourteen days D) Four days?
【解析】 這題當(dāng)中應(yīng)區(qū)分fortnight和four nights之間的發(fā)音。fortnight代表兩個星期，也就是十四天，所以C為正確答案。?
