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.What is stressed in the second paragraph?

There are several ways you can find out about the countries and places you wish to visit. You can talk to friends who have travelled to the places. Or you can go and see a colour film. Or you can read travel books.
It would seem that there are three kinds of travel books. The first are those that give a personal, subjective(主观的) account of travels which the author has actually made himself. if they are informative and have a good index(索引), then they can be useful to you when you are planning your travels. The second kind are those books whose purpose is to give a purely objective(客观的) description of things to be done and seen. If a well-read, cultured person has written such a book, then it is even more useful. It can be sorted as a selected guide book. The third kind are those books which are called “a guide” to some place or other. If they are good, they will, in addition to their factual information, give an analysis or an explanation. Like the first kind they can be inspiring and interesting. But their basic purpose is to help the reader who wishes to plan in the most practical way.
Whatever kind of travel book you choose you must make sure that it does not describe everything as “wonderful”, “excellent” or “magical”. You must also note its date of publication because travel is a very practical affair and many things change quickly in the twenty-first century. Finally, you should make sure that the contents are well presented and easy to find.This passage is about _______.

To face the music
Like every language, American English is full of special expressions, phrases that come from the day-to-day life of the people and develop in their own way. Our expression today is “to face the music”.
When someone says, “well, I guess I’ll have to face the music,” it does not mean he’s planning to go to the concert. It is something far less pleasant, like being called in by your boss to explain why you did this and did that, and why you didn’t do this or that. Sour music indeed, but it has to be faced. At sometime or another, every one of us has had to face the music, especially as children. We can all remember father’s angry voice, “I want to talk to you.” and only because we did not obey him. What an unpleasant business it was!
The phrase “to face the music” is familiar to every American, young and old. It is at least 100 years old. And where did this expression come from? The first explanation comes from the American novelist, James Fenimore Looper. He said, in 1851, that the expression was first used by actors while waiting in the wings to go on the stage. When they got their cue to go on, they often said, “Well, it’s time to face the music.” And that was exactly what they did — facing the orchestra which was just below them. And an actor might be frightened or nervous as he moved on to the stage in front of an audience that might be friendly or perhaps hostile, especially if he forgot his lines. But he had to go out. If he did not, there would be no play. So the expression “to face the music” come to mean “having to go through something, no matter how unpleasant the experience might be, because you knew you had no choice.”
Other explanations about the expression go back to the army. When the men faced an inspection by their leader, the soldiers would be worried about how well they looked. Was their equipment clean, shinny enough to pass the inspection? Still the men had to go out and face the music of the band as well as the inspection. What else could they do?
Another army explanation is more closely related to the idea of facing the results and accepting the responsibility for something that should not have been done. As, for example when a man is forced out of the army because he did something terrible, he is dishonored. The band does not play. Only the drums tap a sad, slow beat. The soldier is forced to leave, facing such music as it is and facing the back of his horse. How many ways does the phrase “to face the music” comes from?
| A．1 | B．2 | C．3 | D．4 |
What’s the meaning of “to face the music?”
| A．To face something far less pleasant. |
| B．To face the stage. |
| C．To face the back of one’s horse. |
| D．To face one’s leader. |
Which of the following is a situation of facing the music?
| A．When we are playing basketball. |
| B．When we are making a speech. |
| C．When we are having a party. |
| D．When we are talking with somebody. |
The underlined word “hostile” means _______.
| A．unfriendly | B．dislike | C．unkind | D．unnecessary |
Informal conversation is an important part of any business relationship. Before you start a discussion, however, make sure you understand which topics are suitable and which are considered taboos(禁忌) in a particular culture. Latin Americans enjoy sharing information about their local history, art, and customs. They expect questions about their family and are sure to show pictures of their children. Yon may feel free to ask similar questions of your Latin American friends. The French think of conversation as an art form, and they enjoy the value of lively discussions as well as disagreements. For them, arguments can be interesting — and they can cover pretty much or any topic — as long as they occur in a respectful and intelligent(智慧的) manner.
In the United States, business people like to discuss a wide range of topics, including opinions about work, family, hobbies, and politics. In Japan, China, and Korea, however, people are much more private. They do not share much about their thoughts, feelings, or emotions because they feel that doing so might take away from the harmonious(和谐的) business relationship they’re trying to build. Middle Easterners are also private about their personal lives and family matters. It is considered rude, for example, to ask a businessman from Saudi Arabia about his wife or children.
As general rule, it’s best not to talk about politics or religion(宗教) with your business friends. This can get you into trouble, even in the United States, where people hold different views. In addition, discussing one’s salary is usually considered unsuitable. Sports is typically a friendly subject in most parts of the world, although be careful not to criticize a national sport. Instead, be friendly and praise your host’s team.The author considers politics and religion ________.
| A．cheerful topics | B．taboos |
| C．rude topics | D．topics that can never be talked about |
Which is typically a friendly topic in most places according to the author?
| A．Sports. | B．Children. |
| C．Personal feelings. | D．Families. |

“If there is one thing I’m sure about, it is that in a hundred years from now we will still be reading newspapers. It is not that newspapers are a necessity. Even now some people get most of their news from television or radio. Many buy a paper only on Saturday or Sunday. But for most people reading a newspaper has become a habit passed down from generation to generation.
The nature of what is news may change. What basically makes news is what affects our lives — the big political stories, the coverage of the wars, earthquakes and other disasters, will continue much the same. I think there will be more coverage of scientific research, though. It’s already happening in areas that may directly affect our lives, like genetic(基因) engineering. In the future, I think there will be more coverage of scientific explanations of why we feel as we do — as we develop a better understanding of how the brain operates and what our feelings really are.
It’s quite possible that in the next century newspapers will be transmitted(传送) electronically from Fleet Street and printed out in our own home. In fact, I’m pretty sure that how it will happen in the future. You will probably be able to choose from a menu, making up your own newspaper by picking out the things you want to read — sports and international news, etc.
I think people have got it wrong when they talk about competition between the different media(媒体). They actually feed off each other. Some people once foresaw that television would kill off newspapers, but that hasn’t happened. What is read on the printed page lasts longer than pictures on a screen or sound lost in the air. And as for the Internet, it’s never really pleasant to read something just on a screen. What is the best title for the passage?
| A．The Best Way to Get News | B．The Changes of Media |
| C．Make Your Own Newspaper | D．The Future of Newspaper |
In the writer’s opinion, in the future, _______.
| A．more big political affairs, wars and disasters will make news |
| B．newspapers will not be printed in publishing houses any longer |
| C．newspapers will cover more scientific research |
| D．more and more people will watch TV |
What will probably be on in the newspaper made by yourself?
| A．Sports and international news. | B．A menu of important news. |
| C．The most important news. | D．What you are interested in. |
From the passage, we can infer _______.
| A．newspapers will win the competition among the different media |
| B．newspapers will stay with us together with other media |
| C．television will take the place of newspaper |
| D．the writer believe some media will die out |
The phrase “feed off” in the last paragraph means _______.
| A．depend on | B．compete with |
| C．fight with | D．kill off |
The number of speakers of English in Shakespeare’s time is estimated(估计) to have been about five million. Today it is estimated that some 260 million people speak it as a native language, mainly in the United States, Canada, Great Britain, Ireland, South Africa, Australia and New Zealand. In addition to the standard varieties of English found in these areas, there are a great many regional and social varieties of the language as well as various levels of usage that are employed both in its spoken and written forms.
In fact, it is impossible to estimate the number of people in the world who have acquired an adequate(足够的) working knowledge of English in addition to their own languages. The purpose for English learning and the situations in which such learning takes place are so varied that it is difficult to explain and still more difficult to judge what forms an adequate working knowledge for each situation.
The main reason for the widespread demand for English is its present-day importance as a world language. Besides serving the indefinite needs of its native speakers, English is a language in which some of important works in science, technology, and other fields are being produced, and not always by native speakers. It is widely used for such purposes as meteorological and airport communications, international conferences, and the spread of information over the radio and television networks of many nations. It is a language of wider communication for a number of developing countries, especially former British colonies. Many of these countries have multilingual populations and need a language for internal communication in such matters as government, commerce, industry, law and education as well as for international communication and for entrance to the scientific and technological developments in the West. What would be the best title for this passage?
| A．The Difficulties of Learning English |
| B．International Communications |

| D．English as a World Language |
Which of the following statements is NOT true?
