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?

Silk production has a long and colourful history unknown to most people. Scientific discoveries have shown that silk production existed in China from around 2500 B.C., although it could be much older. For hundreds of years, China kept the secret of silk to itself as one for the most closely protected secrets in history. Anyone revealing the secret of silkworms or trying to take silkworm eggs out of ancient China was punished by death.
At one time silk was reserved only for the Chinese emperor. Gradually, others began wearing silk. In addition to being used for clothing, silk came to have industrial uses in ancient China, something that happened in the West only in modern times. Silk was used to make musical instruments, fishing lines, weapons, ropes and even paper. During the Han Dynasty silk became a form of money. Farmers paid taxes in both rice and silk. The prices of goods were calculated in lengths of silk just as they had once been calculated in gold. The importance of silk is even reflected in the Chinese language. For example, of the 5000 most common Chinese characters, around 500 have silk as their “key”.
In spite of their secrecy, the Chinese eventually lost their monopoly on silk production. It reached Korea in around 200 B.C. when immigrants from China arrived there. Silk production came to India in 300 A.D.. It was not until 500 A.D. that silk production came to Europe when travellers smuggled out silkworms in hollow tubes of bamboo. These were used to establish silk industry in Rome (modern-day Italy), although Chinese silk was still considered to be the best.
Silk was brought to Rome from China by means of the Silk Road. There were actually two Silk Roads, one over land and one on the sea. The land route in particular had a huge effect in history. All sorts of trade goods — silver, gold, jade, porcelain — passed along this road. Ideas travelled the Silk Road too. For example the religion of Buddhism was carried to China from India by traders on the Silk Road. The Silk Road created the first international culture, exposing many people to the ideas and treasures of both Western and Chinese cultures.How was China able to keep the secret of silk production?
| A．It refused to sell its silk to other countries. |

Michael J. “Crocodile Dundee” (also called Mick), played by Paul Hogan, is the main character in the fictional Crocodile Dundee film series consisting of Crocodile Dundee, Crocodile Dundee II, and Crocodile Dundee in Los Angeles. The character is a crocodile hunter, hence the nickname.
In the first film, Crocodile Dundee, Mick is visited by a New York reporter, Sue Charlton, who travels to Australia to investigate a report she heard of a crocodile hunter, who had his leg bitten off by a crocodile in the outback. The hunter supposedly walked more than a hundred miles back to civilization and miraculously survived his injuries. However, by the time she meets him, the story turns out to be a somewhat exaggerated legend where the “bitten-off leg” turns out to be just being some bad scarring on his leg; a “love bite” as Mick calls it. Still intrigued by the idea of “Crocodile Dundee”, Sue continues with the story. They travel together out to where the incident occurred, and follow his route through the bush to the nearest hospital. Despite his old-fashioned views, the pair eventually become close, especially after Mick saves Sue from a crocodile attack.
Feeling there is still more to the story, Sue invites Mick back to New York with her, as his first trip to a city (or “first trip anywhere,” as Dundee says). The rest of the film depicts Dundee as a “fish out of water,” showing how, despite his expert knowledge of living outdoors, he knows little of city life. Mick meets Sue’s boyfriend, Richard, but they do not get along. By the end of the film, Mick is on his way home, lovesick, when Sue realizes she loves Mick, too, and not Richard. She runs to the subway station to stop Mick from leaving and, by passing on messages through the packed-to-the-gills crowd, she tells him she won’t marry Richard, and she loves him instead. With the help of the other people in the subway, Mick and Sue have a loving reunion as the film ends.Which of the following statements is true about Mick?

It was terribly cold and nearly dark on the last evening of the old year, and the snow was falling fast. In the cold and the darkness, a poor little girl, with bare head and naked feet, wandered through the streets. It is true she had on a pair of slippers when she left home, but they were not of much use. They were very large, so large, indeed, that they had belonged to her mother, and the poor girl had lost them in running across the street to avoid two carriages that were rolling along at a terrible rate. One of the slippers she could not find, and a boy seized upon the other and ran away with it. So the little girl went on with her little naked feet, which were quite red and blue with the cold. In an old apron she carried a number of matches, and had a bunch of them in her hands. No one had bought anything of her the whole day, nor had any one given her even a penny.
Lights were shining from every window, and there was a delicious smell of roast goose, for it was New-year’s eve—yes, she remembered that. In a corner, between two houses, one of which projected beyond the other, she sank down and huddled（蜷缩）herself together. She had drawn her little feet under her, but she could not keep off the cold; and she dared not go home, for she had sold no matches, and could not take home even a penny of money. Her father would certainly beat her; besides, it was almost as cold at home as here.The story happened ________.

| C．on a rainy evening | D．on a snowy night |

The candidate who is longing for election to the highest office in the United States must be native-born American citizen who is at least 35 years old and who has lived in the United States for at least 14 years. The election course is complicated, and the road to the Oval Office is long.
Potential candidates must present papers stating their intention to seek their party’s recommendation; delegates(代表) then choose from among those running some months later at the national conferences. Before that, however, each state holds a primary election that determines how the state’s voters want the party’s delegates to vote. Methods of choosing the delegates vary from state to state. At the conferences, there are speeches and often heated discussions. It may take several rounds of voting before delegates can agree on a candidate. On the final day of the meeting, the presidential candidate announces his or her choice for vice president.
Election Day, by law, is the Tuesday that follows the first Monday in November. On this day, registered voters may cast their votes for president, vice president, and candidates for other federal state, and local offices. The popular vote, however, does not determine who will be president. The president is chosen by a vote of the Electoral College, a group of 538 citizens from the 50 states and the District of Columbia who are chosen to cast votes for the president and vice president.
The rules for choosing electors, as with the delegates, vary. Each state also decides whether its electoral votes must reflect the popular vote. The number of electors in each state is determined by the number of representatives and senators that a state sends to Congress and, therefore, may change every 10 years, depending on the results of the United States census (人口普查). The winner must get at least 270 of the electoral votes when the Electoral College meets in December of the election year. The election results are not official, however, until the following January, when Congress meets in a joint conference to count the electoral votes.
At the end of the road to the Oval Office is the swearing-in ceremony, at which the new or reelected president takes the oath of office on January 20. Which of the following is not a requirement for candidates for the presidency of the USA?
| A．Minimum age of thirty-five years old. |
| B．Native of the United States of America. |
| C．Bottom residency of fourteen years in the State |
| D．Previous experience in an elective office. |
According to the passage, we can conclude that _______.
A. ways to select the delegates of each state are very much the same in the USA.
B. the candidate who wins the popular vote will be the winner of the election
C. the change of a state’s population barely has effects on the presidential election.
D. the presidents of the United States are theoretically picked by the citizens directly.Which of the following might be the best title of the passage?
| A．The Various Ways of Presidential Election in the USA |
| B．The Qualifications for Being the President of the USA |
| C．The Process of the Election for the President of the USA |
| D．The Rules for Choosing Presidential Candidates in the USA |
Julie was preparing for a trip when her phone slipped into a sink full of water. Panic moment! She quickly picked up the wet phone and tried to turn it on, but nothing worked. Her first reaction? She got dressed, drove to the nearest store, and bought a new model at full price.
A new study finds that fear of losing your phone is a common illness. About 66 percent of those surveyed suffer from nomophobia or “no mobile phone phobia”. Interestingly, more women worry about losing their phone than men.
Fortunately, there’s a solution.
The first step is to figure out if you have nomophobia. Checking your phone too often is one thing, but the true sign of a problem is that you can’t conduct business or go about your routine when the fear becomes so severe.
Do you go to unusual lengths to make sure you have your phone? That’s another sign of a problem. If you find you check your phone plenty of times per hour, or a total of an hour per day, there may be a problem.
Some of the treatments are similar to those for treating anxiety attacks: Leaving the phone behind and not checking e-mail or text messages, and then learning to tolerate the after anxiety. Even if this leads to a high level of worry and stress, the solution is to push through the fear and learn to deal with not having your phone.
Of course, there are also technological alternatives. Luis Levy, a co-founder at Novy PR, says he uses an application called Cerberus that can automatically track the location of his phone. To find it, he can just go to a Web site and see the phone’s location.
He also insures his phone through a service called Asurion. The company’s description of its product reads like a prescription for anxiety: “60 million phones are lost, stolen or damaged each year. You’ll have complete peace of mind knowing that your phone is protected and you can quickly reconnect with family, friends and work, as soon as the very next day!”Why does the author mention Kelly’s experience in the first paragraph?
| A．To inform us that mobile phones are useful. |
| B．To introduce the topic for discussion. |
| C．To warn us that we should be careful. |
| D．To tell us we should get phones ready for a trip. |
The underlined word “nomophobia” in Paragraph 2 means ________.
| A．Fear of losing mobile phones. |
| B．Habits of using mobile phones |
| C．Eagerness for new mobile phones. |
| D．Independence of mobile phones. |
Which of the following is a way to treat nomophobia?
| A．Avoiding using phone for some time |
| B．Learning more about modern technology. |
| C．Protecting one’s phone against any damage. |
| D．Not using a mobile phone in one’s daily work. |
Why can the service called Asurion help to treat nomophobia?
| A．It lets you know other people also lose their phones. |
| B．It will give you a new phone through insurance. |
| C．It enables you to reconnect with your acquaintance. |
| D．It gives you a prescription to treat nomophobia. |
What is the passage mainly about?
| A．Solutions to nomophobia. | B．New mobile phone technology. |
| C．Disadvantages of mobile phone. | D．Attitude toward mobile phone. |
