In the 1962 movie Lawrence of Arabia, one scene shows an American newspaper reporter eagerly snapping photos of men robbing a damaged train. One of the robbers, Chief Auda abu Tayi of the Howeitat clan, suddenly notices the camera and snatches it. “Am I in this?” he asks, before smashing it open. To the dismayed reporter, Lawrence explains, “He thinks these things will steal his virtue. He thinks you're a kind of thief.”

As soon as colonizers and explorers began taking cameras into distant lands, stories began circulating about how native peoples saw them as tools for black magic. The “ignorant natives” may have had a point. When photography first became available, scientists welcomed it as a more objective way of recording faraway societies than early travelers' exaggerated accounts. But in some ways, anthropological(人类学的) photographs reveal more about the culture that holds the camera than the one that stares back. Up into the 1950s and 1960s, many ethnographer(人种学者) sought “pure” pictures of “primitive” cultures, routinely deleting modern articles for daily use such as clocks and Western dress. They paid men and women to re-enact rituals or to pose as members of war or hunting parties, often with little regard for truthfulness. Edward Curtis, the legendary photographer of North American Indians, for example, got one Makah man to pose as a whaler with a spear in 1915 — even though the Makah had not hunted whales in a generation.

    These photographs reinforced widely accepted stereotypes that native cultures were isolated, primitive, and unchanging. For instance, National Geographic magazine's photographs have taught millions of Americans about other cultures. As Catherine Lutz and Jane Collins point out in their 1993 book Reading National Geographic, the magazine since its founding in 1888 has kept a tradition of presenting beautiful photos that don't challenge white, middle-class American conventions. While dark-skinned women can be shown without tops, for example, white women's breasts are taboo. Photos that could unsettle or disturb, such as areas of the world torn apart by war or famine, are discarded in favor of those that reassure, to conform with the society's stated pledge to present only “kindly” visions of foreign societies. The result, Lutz and Collins say, is the display of “an idealized and exotic world relatively free of pain or class conflict.”

    Lutz actually likes National Geographic a lot. She read the magazine as a child, and its lush imagery influenced her eventual choice of anthropology as a career. She just thinks that as people look at the photographs of other cultures, they should be alert to the choice of composition and images.

    Imagination Stage is a children's theater in the state of Maryland. A special performance is put on for children with autism (自闭症) each day. People with autism have difficulty communcating and socializing with other people. Children in the theater are allowed to move around during the performance. It's OK if they shout out or hold their ears when the music is too loud. These special performances are sometimes the only thing that a family can go to the theater together to see if a child has autism.

    That is the same idea with Autism on the Seas. This company organizes vacations for families of children with autism, especially vacations on cruise ships. Jamie Grover is director of group development in Autism on the Seas. He said, “With our staff on board, parents know that they are going to be able to relax, enjoy their vacation, and participate in ship activities. They know that their children are well taken care of.”

    The benefit of such vacations organized by Autism on the Seas is not waiting in huge lines on departure day. The company has staff to help in the ports. Waiting in long lines or being in the middle of big crowds can cause problem behavior in children with autism. Autism on the Seas helps families avoid situations like that.

    Autism on the Seas works with the help of cruise companies like Royal Caribbean. Special times or places are arranged for families to play video games, go skating or rock climbing, or eat dinner. Autism on the Seas also directs families to organizations that can help them pay for these vacations.

    Bambi Van Woert from the state of Michigan went on a cruise with her 7-year-old Ben, who has autism. She said, “I would never do something like this myself. I cannot take Ben shopping by myself at this point, so for me to try to do a cruise without help would be absurd.”

The iPhone, the iPad: each of Apple's products sounds cool and has become a fashion. Apple has cleverly taken advantage of the power of the letter “i” — and many other brands are following suit. The BBC's iPlayer — which allows Web users to watch TV programs on the Internet —used the title in 2015. A lovely bear — popular in the US and UK — that plays music and video is called “iTeddy”. A slimmed-down version(简装本) of London's Independent newspaper was started last week under the name “i”.

    In general, single-letter prefixes(前缀) have been popular since the 1990s, when terms like e-mail first came into use.

    Most “i” products are aimed at young people and considering the major readers of independent's “i”, it's no surprise that they've selected this fashionable name.

    But it's hard to see what's so special about the letter “i”. Why not use “a”, “b”, or “c” instead? According to Tony Thorne, head of the Language Center at King's College, London, “i” works because its meaning has become ambiguous. When Apple uses “i”, no one knows whether it means Internet, information, individual or interactive, Thorne told BBC Magazines. “Even when Apple created the iPod, it seems it didn't have one clear definition,” he says.

    “However, thanks to Apple, the term is now connected with portability (轻便) .”adds Thorne.

    ※Clearly the letter “i” also agrees with the idea that the Western World is centered on the individual. Each person believes they have their own needs, and we love personalized products for this reason.

    Along with “Google” and “Microblog”, readers of BBC Magazines voted “i” as one of the top 20 words that have come to define the last ten years.

    But as history shows, people grow tired of fashions. From the 1900s to 1990s, products with “2000” in their names became fashionable as the year was connected with all things advanced and modern. However, as we entered the new century, the fashion disappeared.

    Hacking isn't just for computers and smartphones, According to a study published last week in the journal Science, scientists have found a way to hack a plant's genes in order to make it use sunlight more quickly. Someday, the results could increase the amount of food produced around the world.

    Photosynthesis（光合作用）is the word used to describe how plants use sunlight, water, and carbon dioxide to make their own food. Scientists who conducted the new study say this is a very slow process. Plants use less than 1 percent of the energy available to therm. But by hacking a plant's genes, the scientists were able to increase the amount of leaf growth on plants between 14 and 20 percent.

    "Specifically, scientists hacked the plant's protective system. Normally, this system is activated when a plant gets too much sunlight, "said scientist Krishna Niyogi, co-author of the study. When the plant senses the light, it gets rid of extra energy and creates more leaves. When the plant is in shade, the protective system is turned off, but the process is slow.

    Stephen Long is the lead author of the study. He compared a plant's protective system to light-adjusting glasses. When a person wears the glasses outside during the day, the lenses（镜片）darken and lighten depending on how sunny it is. Plants do the same thing, he said. But in plants the adjustment can take anywhere from 10 minutes to an hour. This makes it hard for plants to get the right amount of sunlight needed to create food.

    The new study sped up the process. By changing the plant's genes, the protective system turned on and off more quickly than normal. As a result, leaf growth on the plants scientists used in the study increased. Leaf growth in two plants increased by 20 percent, while leaf growth on a third plant increased by 14 percent. Scientists conducted the study on tobacco plants. But they think the genetic changes will produce the same results in corn and rice.

Tests have shown robots can diagnose heart problems in as little as four seconds, as a review of artificial intelligence (AI) finds machines are now as good at spotting illness as doctors.

Analyzing a patient's heart function on a cardiac MRI (心脏磁共振成像) scan currently takes doctors around 13 minutes. But a new trial by University College London (UCL) showed an AI program could read the scans in less time with equal accuracy. There are approximately 150,000 such scans performed in the UK each year, and researchers estimate that fully using AI to read them could save 54 clinician-days (临床天数) at each cardiac centre per year. So it can make up for the shortage of doctors.

It is hoped that AI where computer systems are able to learn from data to identify new patterns with minimal human intervention will transform medicine by helping doctors spot diseases such as heart disease and cancer faster and earlier. However, most scans are still read by specially trained doctors.

Dr Charlotte Manisty, who led the UCL research, said, "Cardiovascular MRI offers in- comparable image quality for assessing heart structure and function. However, current manual analysis remains basic and outdated. Automated machine techniques offer the potential to change this and completely improve efficiency and accuracy, and we look forward to further research that could confirm the superiority to human analysis."

She added, "Our dataset of patients with a range of heart disease who received scans enabled us to demonstrate that the greatest sources of measurement errors arise from human factors. This indicates that automated techniques are at least as good as humans, with the potential soon to be 'super-human'—transforming clinical and research measurement precision."

Professor Alastair Denniston said, "Within those handful of high-quality studies, we found that by deep learning AI could indeed detect disease ranging from cancer to eye disease as accurately as health professionals. But it's important to note that it did not absolutely exceed human professional diagnosis. "

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.
