A new generation addiction is quickly spreading all over the world. Web holism, a twentieth century disease, affects people from different ages. They surf the net, use e-mail and speak in chat rooms. They spend many hours on the computer, and it becomes a compulsive （强迫的，强制的） habit. They cannot stop, and it affects their lives.

    Ten years ago, no one thought that using computers could become compulsive behavior that could affect the social and physical life of computer users. This obsessional behavior has affected teenagers and college students. They are likely to log on computers and spend long hours at different websites.

    They become hooked on computers and gradually their social and school life is affected by this situation. They spend all free time surfing and don't concentrate on homework, so this addiction influences their grades and success at school. Because they can find everything on the websites, they hang out there. Moreover, this addiction to websites influences their social life.

    They spend more time in front of computers than with their friends. The relation with their friends changes. The virtual life becomes more important than their real life. They have a new language that they speak in the chat rooms and it causes cultural changes in society.

    Because of the change in their behavior, they begin to keep themselves apart from the society and live with their virtual friends. They share their emotions and feelings with friends who they have never met in their life. Although they feel confident on the computer, they are not confident with real live friends they have known all their life. It is a problem for the future. This addictive behavior is beginning to affect all the world.

    Are you content with the shape of your nose? If not, the climate may be to blame, not your parents.

This is according to a recent study carried out by scientists from Pennsylvania State University, US. They found that climate played a key role in shaping our noses. The findings were based on an examination of the size and shape of noses of 476 people from four regions—West Africa, East Asia, South Asia and Northern Europe, using 3-D facial imaging technology.

     “People have thought for a long time the difference in nose shape among humans across the world may have arisen as a result of natural selection because of climate,” Arslan Zaidi, one of the lead authors of the study, told The Guardian. But while previous studies were based on measurements from human skulls, Zaidi and his team looked at nose shape itself.

    The result showed that wider noses are more common in warm and humid climates, while narrower noses are more common in cold and dry climates. That, Zaidi said, could be because narrower nasal passages help to increase the moisture (潮湿) content of air and warm it，which is easier on our lungs. This, in turn, led to a gradual decrease in nose width in populations living far away from the equator.

    More study is still needed to test the link between climate and nose shape, but Zaidi believes the current findings are valuable in understanding potential health issue. “As we become more of a global community, we are going to come across climates that we are not adapt to,” he told the Guardian. This means moving to a very different climate might increase the risk of breathing problems.

    However, he added, “This may not be necessarily true for various reasons such as of modern medicine and the fact that our current climate is very different from what it used to be.”

    A good book is indeed the best friend of a person.The same goes for high—profile CEOs of world recognized companies as well.Let's have a look at the favorite books of some of the world-famous CEOs.

    Apple CEO—Tim Cook,Competing against Time by George Stalk Jr.and Thomas M.Hout

    This book is based on 10 years of valuable research done by the authors.It talks about how new concepts of managing time in new product development,production and sales provide companies with the advantages to succeed in this highly competitive world.

    Microsoft CEO(Former)—Bill Gates,The Catcher in the Rye by J.D.Salinger

    A few themes explored in the novel are rebellion（叛逆）,anxiety and confusion.It admits that young people are a little confused,but can be smart about things and see things that adults don't really see.Gates said,"I didn't actually read The Catcher in the Rye until I was 13,and ever since then I've said that's my favorite book."

    Oracle CEO—Larry Ellison,Napoleon by Vincent Cronin

    This book is considered by far the best biography ever written on Napoleon Bonaparte.Ellison said,"It's interesting to read about him for a couple of reasons: to see what an ordinary man can do with his life and to see how history can distort（歪曲）the truth entirely."

    OWE CEO—Oprah Winfrey,To Kill a Mockingbird by Harper Lee

    This book talks about how a little girl observes the people around her.Winfrey said,"I read it in eighth or ninth grade,and I was trying to persuade other kids to read the book.So it makes sense to me that now I have a book club, because I have been doing that probably since I read this book."

    In the depths of the French Guianese rainforest, there still remain unusual groups of (土著的）people. Surprisingly, these people live largely by their own Laws and their own social customs. And yet, people in this area are in fact French citizens because it has been a colony of the French Republic since 1946. In theory，they should live by the French law. However, their remote locations mean that the French law is often ignored or unknown, thus making them into an interesting area of “lawlessness” in the world.

    The lives of these people have finally been recorded thanks to the effects of a Frenchman form Paris called Gin. Gin spent five months in early 2015 exploring the most remote comers of thin area, which sits on the edge of the Amazon rainforest, with half its population of only 250,000 living in its capital, Cayenne.

    “I have a special love for the French Guianese people. I have worked there on and off for almost ten years," says Gin. "I've been able to keep firm friendships with them. Thus I have been allowed to gain access to their living environment. I don't see it as a lawless Und. But rather I Me it as an area of freedom."

    “I wanted to show the audience a photographic record touching upon the uncivilized life," continues Gin. “I prefer to work in black and white, which allows me to show different specific worlds more clearly.”

    His black-and-white pictures present a world almost lost in time. These pictures show people seemingly pushed into a world that they were unprepared for. These local citizens now have to balance their traditional self-supporting hunting lifestyle with the lifestyle offered by the modern French Republic, which bring with it not only necessary state welfare, but also alcoholism, betrayal and even suicide.

    Google's new camera, called Clips, is a small, smart device. It comes with a case that has a clip (夹子)，but it's not designed to be worn on your clothing. Most interestingly, it uses artificial intelligence to take photography out of your hands so it can capture moments on its own.

    This roughly 2-inch by 2-inch camera, with a three-hour battery life and Gorilla Glass for toughness, is intended for candid moments, like when a child does something cute that may happen too quickly for you to pull out your smartphone.

On board the Clips device, it uses machine learning algorithms (计算程序) to help capture scenes. Those algorithms include face recognition. “Once it learns that there's a face you see frequently, it'll try to get nice photos of those faces,” said Juston Payne, the device's product manager. And they also want it to recognize facial expressions, which involved “training it to know what happiness looks like”. The Google team also trained it to recognize what not to shoot — like when a child's hand is over the lens, or if it is tossed in a dark purse.

    The only way to see the images is by connecting the camera with your phone, as it has no screen for viewing or editing.

    Were people concerned it could seem strange? Yes, Payne admitted. But they said they addressed that by making it obvious what it is. A green light on the front signals that it is on. Besides, unlike a camera meant to monitor your home, it is not connected to the Internet.

    “This product is only possible because of the way that silicon has advanced” Payne said, noting that it was only in the past year or so that they could squeeze the technology down into a device this size. Going forward, we're likely to get more assistance from the artificial intelligence packed into our apps and gadgets.

    The Notre Dame fire has been put out, but its spire and a large portion of its wooden roof have been damaged. The terrible destruction causes a sudden sharp pain to people around the world. On Chinese social media network Wechat a common comment on the disaster is: "What a pity that we cannot see the damaged parts of the wonder anymore."

    But the good news is that there is at least one way of seeing them, namely via a video game called Assassin's Creed: Unity. In this game, the player can travel to one city after another and enter the buildings exactly like what they are in reality, and see Notre Dame as it was before the fire. Further, with virtual reality technology, which is already quite mature, one can even look around the undamaged Notre Dame as if it is still there. Maybe digital technology could help to better protect architectural cultural heritage.

    The idea of digitizing ancient buildings, making digital models of them so their data can be saved, dates back to the 1990s and the necessary technology has continued to advance since then. By scanning the ancient buildings with lasers, building 3D models with multiple images, as well as measuring everything precisely, engineers can make a copy as accurate as the real one.

    As computers and smartphones are hugely popular, the digital replica（复制品）has great use value  First, it allows tourists to feel the cultural relics without touching them, which helps protect them. The virtual tour of Dunhuang Grottoes in Gansu Province is a good example of this as tourists can view the paintings without standing near them. Furthermore, it can make the digitized cultural relics more famous by spreading awareness about them via the Internet. In 2000, a virtual tour of the Great Wall became very popular at the Hannover World Expo, which increased the number of foreign tourists visiting the site in the following years. Above all, it preserves all the information of the cultural relics. Even if the original ones are damaged one day, people can still know what they were like and can build a replica if desired.

    Of course, however precise a model is, it is not the original. Time is the biggest threat to a country's architectural heritage, which will always become ruins with the passing of time. Maybe we will have better technologies in the future, but the digital technology offers a practical way to preserve architectural cultural heritage at the moment.
