Karen Bystedt was born in Israel, but lived in London and California as a child. In 1982, as a photography (摄影) student at New York University, she was photographing male models for a book when she came across an ad featuring Andy Warhol, a very famous artist. She thought it would be really great to put him in her book.

    So she called Andy Warhol at his studio in Union Square and asked if she could photograph him.

Two weeks later, Bystedt took a rented Hasselblad camera and lights to Warhol's famed "Factory" on 14th street. She ended up taking 36 pictures, and published two in her book, Not Just Another Pretty Face, published in 1983. Warhol came to its launch (发行) party—and that was the last time she saw him.

    A few years later, she packed the portraits in a box and moved to Los Angeles. But after she'd gotten settled, she couldn't find them. She couldn't remember whether she had given the photos away or just left them in some forgotten storage unit. Either way, she thought they were lost forever.

    In 2011, Bystedt became determined to find the missing films(底片). She spent two weeks going through two old garages, where she had put a bunch of belongings decades before. In a cardboard box, she found ten of the original films, covered in dust. She and a friend spent four months digitizing and cleaning the images up, pixel(像素) by pixel.

    Bystedt was not content to merely publish the unseen photos. She invited contemporary artists to paint over and around her Warhol pictures, breathing new life into her old work. So she began reaching out to artists, seeing if they would be interested in putting their own stamp on the pictures.

    The responses was overwhelming. Bystedt's new exhibit, "The Lost Warhols," opened on May 1, 2018 at 178 Sixth Avenue in Soho, New York, included 66 different interpretations of her portraits from 34 artists.

Most young people enjoy some form of physical activity. It may be walking, cycling or swimming, or winter, skating or skiing. It may be a game of some form—football, hockey, golf or tennis. It may be mountaineering.

    Those who have a passion for climbing high and difficult mountains are often looked upon with surprise. Why are men and women willing to suffer cold and hardship, and to take risks on high mountains? This astonishment is caused, probably, by the difference between mountaineering and other forms of activity to which men give their leisure.

    Mountaineering is a sport and not a game. There are no man-made rules, as others, as there are for such games as golf and football. There are, of course, rules of a different kinds which would be dangerous to ignore, but it is this freedom from man-made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.

    If we compare mountaineering with other more familiar sports, we might think that one big difference is that mountaineering is not a “team game”. We should be mistaken in this. There are, it is true, no “matches” between “teams” of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously teamwork.

    The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport requires high mental and physical qualities.

    A mountain climber continues to improve in skill year after year. A skier is probably past his best by the age of thirty. But it is not unusual for men of fifty or sixty to climb the highest mountains in the Alps. They may take more time than younger men, but they perhaps climb with more skill and less waste of efforts, and they certainly experience equal enjoyment.

Both humans and animals have enemies. 11 is easy for us to know the difference between our friends and our enemies. But can other animals do the same? Elephants can! They can use their sense of vision and smell to tell the difference between people who mean a threat and those who do not. In Kenya, researchers find that elephants react differently to clothing worn by men of the Maasai and Kamba ethnic groups. Young Maasai men hunt animals and thus mean a threat to elephants; Kamba men are mainly farmers and are not a danger to elephants.

In an experiment conducted by animal scientists, elephants were first presented with clean clothing or clothing that had been worn for five days by either a Maasai or a Kamba man. When the elephants noticed the smell of clothing worn by a Maasai man, they moved away from the smell faster and took longer to relax than when they noticed the smells of either clean clothing or clothing worn by a Kamba man.

Clothing color also plays a role. In the same study, when the elephants saw red clothing not worn before, they reacted angrily, as red is typically worn by Maasai men. Rather than running away as they did with the smell, the elephants acted angrily toward the red clothing.

The researchers believe that the elephants' emotional reactions arc due to their different senses of smell and sight. Smelling a possible danger means that a threat is nearby and the best thing to do is run away and hide. Seeing a potential threat without its smell means that risk is low. Therefore, instead of showing fear and running away, the elephants express their anger and become aggressive.

    Compared with solar and wind energy, which are booming, tidal (潮汐的) power is a loser in the clean - energy competition. But if you did want to build a tidal power station, there are few better sites than the mouth of the River Severn, in Britain. Its tidal range, the difference in depth between high and low tides, of around 15 metres is among the largest in the world.

    Engineers and governments have been toying with the idea since at least 1925. But none of the suggested projects has materialised. Price is one objection. A study thought that tidal energy might cost between ￡216 and ￡368 ($306 - 521) per MWh of electricity by 2025, compared with ￡58 - 75 for seagoing wind turbines (轮机) and ￡55 - 76 for solar panels. Environmentalists also worry that any plant would change the tides, making life harder for wildlife.

    An engineer called Rod Rainey thinks he has a way around both problems. He plans to replace the conventional turbines of previous plans with a much older technology. Specifically, he plans to span (横跨) the river mouth with a line of water wheels. This is a design that dates back to the early days of the Industrial Revolution. Examples can be found fixed to the sides of old watermills (水磨).

    But there would be nothing old - fashioned about Mr Rainey's wheels. Thirty metres high and sixty wide, they would be made from ordinary steel. Two hundred and fifty of them, along with the supporting structures, would be floated into place and secured to the seabed, creating a line 15km long. Together, they could supply power at an avenge ate of 4GW. That is about as much as two biggish nuclear power stations would manage. Substituting one of the wheels with a set of locks would provide a shipping channel about twice the width of Panama Canal, permitting upstream ports such as Avonmouth and Cardiff to continue operating.

The Harbourside Development is one of the world's most exciting places to shop. It's built right on the edge of Sydney Harbour, and there are over 200 shops, selling everything from home­made sweets to the very latest clothes in fashion; from Australian souvenirs to Swiss watches and Japanese cameras.

The Australian Wildlife Park has been specially built to give people an extra close look at Australia's native animals. Have your photo taken with a kangaroo，touch and feed koala bears. There are talks every afternoon about these animals, which are only found in this part of the world. There is also an excellent souvenir shop.

A visit to the Australian Museum is like an adventure across Australia. There are shows on the people and their way of life and the whole continent. Talks and guided tours help to make your visit unforgettable. There's also a café and a good book shop, selling excellent maps.

Taronga Zoo has Australia's finest collection of rainforest birds and sea­life centre which has many of the fish that can be found off the coasts of Australia and New Zealand. Taronga is also famous for its large group of South East Asian monkeys. Fast food can be got at cafés.
