            数字和计算(下集)  

数字
  还记得上次我给你介绍了一些听数字和计算的技巧吗,不知你用到了没有,今天我要先请你来听一道题:
M: This black bag is 2.00 and that blue one is a dollar more.
  W: The red one is twice as much as the blue one.
  Q: How much are two red bags?
  You will read:
   a. $4.00  b. $6.00  c. $8.00  d. $12.00
 

  你一定要说:“这个,简单。都是2呀3呀的, 难不倒我。Black为 2 元,blue 多1元为3,red 是蓝的两倍为6元,答案为b. 对不对?”

  如果你的判断是这样,我得很遗憾地告诉你:“你错了。”

  可是哪里有错呢。我们再来听一遍题目:

M: This black bag is 2.00 and that blue one is a dollar more.
  W: The red one is twice as much as the blue one.
  Q: How much are two red bags?

  原来问题出在two red bags两个红色的包,看看你是不是太粗心了。记住在听力答题中要保持一个清醒的头脑,稳扎稳打是成功的重要保证。

  最后,我想:你还应知道数字的一些规范读法,因为同一数字概念可用不同的形式表达,这种情况主要出现在天、钟点、星期等时间的表示方法上。

11:45  a quarter to twelve 与eleven forty-five
2:30 two thirty与half past two
前天 the day before yesterday 与two days ago
后天 the day after tomorrow 与two days later
每天 day by day 或each day 与from day to day
两星期 fortnight与 (period of ) two weeks
前几天 the other day 与 a few days ago
9,743: nine thousand, seven hundred and forty-three
19,857,242 nineteen million, eight hundred and fifty-seven thousand
  two hundred and forty-two
1990年: nineteen ninety / nineteen hundred ninety
May 1 (st): May first/the first of May
24:00: twenty-four/ midnight
1/2: one half / a half
3/4: three fourth / three quarters
1/3 : one-third

  了解了这些,我想有关数字和计算的题目,你心里应该有底了。下次再试试我为你准备的各种练习保证你万无一失。
