In ancient Egypt, a shopkeeper discovered that he could attract customers to his shop simply by making changes to its environment. Modern businesses have been following his lead,with more tactics（策略）.

One tactic involves where to display the goods. Foe example, stores place fruits and vegetables in the first section. They know that customers who buy the healthy food first will feel happy so that they will buy more junk food（垃圾食品）later in their trip. In department stores, section is generally next to the women's cosmetics(化妆品) section：while the shop assistant is going back to find the right size shoe, bored customers are likely to wander over cosmetics they might want to try later.

Besides, businesses seek to appeal to customers' senses. Stores notice that the smell of baked goods encourages shopping, they make their own bread each morning and then fan the bread smell into the store throughout the day. Music sells goods, too. Researchers in Britain found that when French music was played, sales of French wine went up.

           When it comes to the selling of houses, businesses also use highly rewarding tactics. They find that customers make decision in the first few second upon walking in the door, and turn it into a business opportunity. A California builder designed the structure of its houses smartly. When entering the house, the customer would see the Pacific Ocean through the windows, and then the poll through an open stairway leading to the lower level. The instant view of water on both levels helped sell these $10 million houses.

    Tens of thousands of ancient pictures carved into the rocks at one of France's most important tourist sites are being gradually destroyed. Scientists and researchers fear that the 36,000 drawings on rocks in Mont Bego in the French Alps are being damaged so rapidly that they will not survive for future generations.

    The mountain, believed to have once been a site for prayer, is scattered (散布) with 4,000-year-old drawings cut into bare rock. They include pictures of cows with horns, cultivated fields and various gods and goddesses. But as the popularity of the site increases, the pictures are being ruined by thoughtless graffiti (涂鸦).

    Jean Clottes is the chairman of the International Committee on Rock Art. He says, "People think that because the pictures have been there so long they will always continue to be there. But if the damage continues at this rate there will be nothing left in 50 years."

    He describes seeing tourists stamping on the drawings, wearing away the rock and definition (清晰) of the artwork as they do so. Some visitors, he says, even cut off parts to take home as souvenirs. "When people think they can't take a good enough photograph, they rub the drawings to get a clearer picture," he said. "The drawings are polished by the weather, and if the sun is shining and the visitors can't see them properly they simply rub them to make them look fresher." Other researchers describe how people arrive carrying long sticks with sharp ends to scratch (刮) their own drawings, or even their names, in the rocks.

    But experts are divided over the best way to preserve the drawings. Henry de Lumley, director of the Museum of Natural History in Paris, believes that the only way to save the site is to turn the whole mountain into a "no-go" area, preventing the public from going there except on guided tours. Otherwise, he says, not only will the site be completely destroyed but important research work will be reduced.

    Clottes disagrees, "The measure suggested by Henry de Lumley is the most severe, and while it is the most effective, it is also certain to bring about protests from people who live there," he said. "The site was classified as a historic monument years ago by the Ministry of Culture, and we must do as much as possible to save what is there."

    David Lavergne, the regional architect, also wants to avoid closing the site. "Henry de Lumley's idea isn't ideal," he said. "Our department feels that the best solution is to let people look at the site, but because the area is very big it is difficult to prevent visitors from damaging it. I would prefer that everyone was able to look at it, but the main problem is money. We do not have the funds to employ the necessary number of guards. We may have to consider charging a fee. It doesn't seem to be possible to get the government support."

Oxford English Dictionary (OED) announced on November 23 for the first time that it has chosen not to name one single word of the year, but many words for the "special" year 2020. Describing 2020 as "a year which cannot be neatly summarized in one single word". OED said on Monday that there were too many words to sum up the events of 2020. From more than 11 billion words found in web-based news, blogs and other text sources, its lexicographers(词典编纂者)revealed what the dictionary described as "great shifts in language data and frequency rises in new words" over the past 12 months.

Most words of the year are coronavirus-related, including coronavirus, lockdown, circuit-breaker, keyworkers and face masks. The report said the word "coronavirus" dates back to the 1960s and was previously "mainly used by scientific and medical specialists". But by April this year it had become one of the most frequently used nouns in the English language, beyond even the usage of the word "time". It said use of the word "pandemic" has increased by more than 57,000 percent this year.

The revolution in working habits during the pandemic has also affected language, with both "remote" and "remotely" seeing more than 300 percent growth in use since March. "On mute(静音)"and "unmute" have seen 500 percent rises since March, while the words "workation" and "staycation" also increased drastically.

Casper Grathwohl, the president of Oxford Dictionaries, said. "I've never witnessed a year in language like the one we've just had. The Oxford team was identifying hundreds of significant new words and usages as the year unfolded." "2020 has been filled with new words unlike any other," Grathwohl added.

The OED's announcement mirrored the huge influence of the COVID-19 on the people from all walks of life. To bring life back to normal, countries such as Britain, China, Germany, Russia and the United States are racing against time to develop coronavirus vaccines.
