15.Bar codes are one way that the U.S.Postal Service streamlines mail of the wrong hands.A letter that comes without a bar code or cancelled stamp might not have been processed by the U.S.Postal Service and it might indicate that something's fishy.(可疑的)Can you decode a bar code the way the U.S.Postal Service can?Here's How
1.Here's how to read the bar code on your letter.
•Most U.S.letter bar codes have bars of two lengths:long and short.
•Every bar code should start and end with long bars; ignore those.
•Look at the rest of the bars in groups of five,starting with the second bar.Each group of five represents one digit.(数字)
2.Here's how to figure out what those digits are.
•The five bars stand for one of these numbers:7,4,2,1,0.
•Some genius figured out that this range would allow you to come up with the digits 0to 9.You do it by adding the numbers of the long bars together.
Say you have this bar code:
Here,the 4and 2places have long bars.Added together,they total 6,so this bar code stands for 6.
Say you have this bar code:
The 1and 0places have long bars.Added together,they total 1,so this bar code stands for 1.
Say you have this bar code:
The 7and 4pieces have long bars.Added together,they total 11,but there is no 11in this system,so this bar code stands for 0.
3.Now let's look at the bar code on a letter.
Ignore the first and last bars of the whole bar code.Then look at the next 20bars to find the zip code (0680).The next two sets of five bars give your mail carrier's number (10153).The rest of the bars in the bar code indicate the house or maibox number.The house number is 32.
63.Why does US Postal Service just use five numbers for the five bars?D
A.They are easy to read. B.They are ohosen only by accident.
C.They can stand for the long bars. D.They are enough to make ten digits.
64.Which of the following bar codes otands for"7"according to the text?B

解答 63-66 DBCB
63.答案D.细节理解题.根据第二部分第二段"Some genius figured out that this range would allow you to come up with the digits 0to 9"可知,这五个数字就足够组成0--9之间的数了.故选D.
64.答案B.推理判断题.根据第二部分"Say you have this bar code:Here,the 4and 2places have long bars.Added together,they total 6,so this bar code stands for 6."和"Say you have this bar code:The 1and 0places have long bars.Added together,they total 1,so this bar code stands for 1."可知,五个数字的顺序是不变的,把最高那条代表的数字加起来就是这个条码代表的数字.A选项最高条码为7,4,代表11,根据"The 7and 4pieces have long bars.Added together,they total 11,but there is no 11in this system,so this bar code stands for 0."可知,A为0.B最高条码为7,0,加起来为7.C最高条码为7,2,密码为9.D最高条码为2,0,密码为2.故答案选B.
65.答案C.推理判断题.根据第三部分第一段"Then look at the next 20bars to find the zip code (0680)."可知,邮政编码与条码要一致.故选C.
66.答案B.写作目的题.根据文章第一段"Can you decode a bar code the way the U.S.Postal Service can?Here's How"可知,本文主要讲解如何从邮局的条码中找到对应的数字及地址.故选B.
