Barcodes (条形码) aren’t given much thought by the majority of consumers, but these codes were fairly recently applied in a working fashion in 1970.
A small food store owner decided one day that keeping records of the inventory (存货) of his stock and the associated prices were an extremely laborious process, and so, in 1948, he contacted the The Drexel Institute of Technology in a bid to work towards a solution. Bernard Sliver rose to the challenge and set out to study the problem, and began working on a solution involving an automatic way of keeping track of items that had been sold. Silver and a group of students from the institute realized their answer in the form of ultraviolet light (紫外线), ink and a scanner.
The system worked initially, but possessed some negatives. It was incredibly costly to carry out on a large scale and the system was also unstable. If the invention was to become commonplace (寻常的事) in grocery stores, these two problems had to be solved.
The patent (专利)for the bar code system was filed by Sliver and one of his students, Woodland. The patent was not granted immediately; in fact it took three years for the patent agency to grand their invention patent for the barcode, occurring on 7th October, 1952.
Despite the patent being issued, the system was still not welcomed by the majority of store owners. It was not until 1966 that the system began moving its way into more and more grocery stores. This system was soon criticised, as there was no central mechanism for controlling uniformly coded items. In 1970, Logicorn developed the Universal Grocery Products Identification code (UGOIC), soon shortened to Universal Identification Number (UPC). It was Marsh’s superstore, in Troy, which was the very first store to install this complex barcode reading system, and its popularity has soared (升温) ever since, and is obviously now commonplace in all types of stores worldwide.

A．The heavy work of store owners.

Flying across the globe, whether on business or for leisure, is usually effortless——you just have to book your ticket, pack your bags and show up at the airport with your passport. You board the plane and several cocktails and movies later, you arrive at your destination, and hopefully, your baggage does too. Here are some tips on how to be a clever traveler.
Easy check-in
Avoid the queue and check yourself in by using the MAS Web Check-In (malaysiaairlines.com) in the comfort of your own home or office. Passengers can now check in online anytime from 24 hours to 90 minutes ahead of the scheduled departure time. This is available for flights departing from all MAS stations ——except Paris, Kunming, Xiamen and Bandar Seri Begawan——to all MAS destinations. You can even select preferred seats online.
Bag hygiene
No, we’re not talking about the cleanliness of your bags! It’s the aviation talk for a bag that doesn’t carry any old baggage tags with barcodes that could confuse the baggage sensor（传感器）.
If you find yourself arriving in Sydney while your bag lands in Tokyo, it could be because of your old baggage tag. Another reason why bags go missing could be the printing quality of the barcode; bags are misdirected because the sensors can’t re
ad the codes correctly.
Less is more
Most airports around the world now set a weight limit of 32kg per piece of baggage. This will not only help protect the airline workers’ health, but also be easier for you to carry your bags around.
Avoid packing dangerous goods or placing valuables inside your check-in luggage. Ensure that locks are properly secured as a lot of baggage locks are found caught between the conveyor belts（传送带）. Smaller and softer bags are usually placed inside a tra
y at check-in to protect the locks from contact with the conveyor belt.
【小题1】According to the passage, airplane passengers ______.
| A．can check in without going to the airport |
| B．have to check in 90 minutes earlier |
| C．are required to check in on the MAS web |
| D．can select their favorite seats when getting aboard |
| A．Disappearance. | B．Protection. |
| C．Check. | D．Cleanliness. |

科目：高中英语 来源：2011-2012学年安徽省高三第七次月考英语试题 题型：阅读理解
How can you hear your friends’ voices when they are far away and you can’t make a long—distance call? Besides the web camera system with your computer, we have a new high-tech way to solve the problem and ease your pain of missing them.
The Japanese company Combiwith created a system—“talking picture”. It makes people in pictures speak!
The “talking picture” has a special pen. It is actually a pen-shaped scanner. It can scan information in special—made pictures. A connected player will then play the information out loud.
First, you need to take a picture and record what you want to say with the company. The company will then make special barcodes(条形码) onto your picture(you can’t see those codes). Those codes are your voice and your words. When you hold up the pen to scan your picture with barcodes, a player connected to the pen will start to play. It plays things you’ve recorded. That way the invention makes the “you” in the picture speak!
Do you want your friends and families talking out of pictures? Have them make pictures like that, and you can hear them whenever you want, only with the “talking picture” system. The system can play messages for up to 12 minutes.
“The pictures would be useful for those who hope to hear the voice of someone living far away,” said Mayumi Fuji, a spokeswoman for the company. “Grandparents, for example, longing to know about their grandchildren, would be happy to hear their voice when they see the picture,” Fuji said.
But it is troublesome to go to the company for taking a special picture first. And, it is much more expensive than using a telephone. The photo with barcodes costs between 17,040 and 17,990 yen(日元)(160 and 169 dollars). The larger picture you want, the more you pay.
Now, just raise a finger, lonely people can have their loved ones speak out of pictures. But, whether the “talking picture” is practical or not, let’s wait and see.
1.What does “talking pictures” mean according to this article?
|
A．The picture can play what’s been recorded as if the person in the picture “talks”. |
|
B．You can have a talk with the person in the picture whenever you want to. |
|
C．The picture can tell you wonderful stories to ease your pain. |
|
D．The picture can tell what’s on your mind when you are looking at it. |
2.If you want to make a talking picture, you need to ________.
|
A．take a picture and record what you want to say with the company |
|
B．make special barcodes onto your picture |
|
C．a pen—shaped scanner to go with the picture |
|
D．All of the above |
3.Which of the following is NOT true accordingly?
|
A．The talking picture system can play messages for 12 minutes at most. |
|
B．It will cost you more to take a larger talking picture. |
|
C．It might take a lot of trouble to make a talking picture. |
|
D．You can make a talking picture by just raising a finger. |
4.What is the attitude of the author?
|
A．Optimistic. |
B．Uncertain. |
C．Positive. |
D．Pessimistic. |
