A handsome man can earn a fifth more than an average-looking colleague but a beautiful woman is not paid a penny more than her average-looking colleague, new research has shown.

    The study by senior economists（经济学家）found that being good-looking meant male workers could earn 22 percent more than average-looking colleagues. Researchers said good looks did not give women a similar advantage.

    Andrew Leigh, a former economics professor at the Australian National University who co-authored the report, said: “Beauty can be a double-edged sword for women.”

    “Some people still believe good looks and intelligence are incompatible(矛盾的) in women, so a good-looking women can't be that productive, but it doesn't affect men's pay.”

    He said that although he believed good-looking women may also earn more, the research did not support his theory.

    The research found that handsome men in all jobs, from manual labour（手工劳动）to highly-paid professional careers, can earn 22 percent more than their colleagues doing the same work.

    Men with below-average looks face a battle in the office, with ugliness reducing a man's earnings by 26 percent compared to an average-looking worker.

    Former male model, Caitlan Mitchell, 28, who has a first class degree in history from Edinburgh University and now works for a cosmetics company, told the Sunday Times:' It gives you confidence, and I suspect people tend to warm to you more quickly.”

    The study, named Unpacking the Beauty Premium, was the largest exercise of its kind and repeated a survey from 1984 to see if the beauty premium（美貌溢价) had changed.

    Leigh said the research showed people in the workplace were “lookist(以貌取人的)”and he hoped the findings would encourage employers to remove their prejudice.

    A recent study led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility (能见度） of yellow makes it less difficult for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate.

    The study was led by Prof Ho. To test whether there was a relationship between the color of a taxi and the number of accidents the taxi had, the research team analysed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6. 1 fewer accidents per 1,000 taxis per month.

    They also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio (比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76. 6 fewer accidents will occur per month or 917 fewer accidents per year.

    Assuming an average repair cost of $1,000 per car and a downtime of six days, the color of all taxis to yellow could produce an annual saving of $2 million.

    “We are eager to continue to validate (证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we' re also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors explained Prof Ho.

    When people ask me to name typical British dishes,I have,however,struggled to think of an answer.Yes,we do have our own national dishes.We do have fish and chips,and we have other dishes like roast dinner and shepherd's pie.But how much do we actually eat them?

    Fish and chips,is made up of battered（绞碎的）fish and chips,which is often accompanied by a thick paste（酱）. The majority of British people really do love this dish but it is not something that we would eat,say,on a weekly basis.It's also not usually something that we would cook at home.The British people associate this dish with the seaside and it's something that will usually be eaten on a day trip there,bought from a takeaway fish and chip shop.

    Another favourite British dish is roast dinner.This is made up of roast meat,usually chicken or beef, accompanied by roast vegetables and a meat sauce called gravy（肉汁）.It is usually eaten on a Sunday,perhaps for a special family dinner.It can either be cooked at home or eaten in a traditional pub.We also eat a more elaborate version of this for our Christmas dinner.

    Although we do have our traditional dishes,our diet has been greatly influenced by other countries.You can find a wide range of international foods in the supermarket or varieties of different restaurants on our high streets.A famous saying amongst British people is that our national dish is now chicken tikka masala,a dish which is heavily influenced by Indian cuisine.

    Don't expect to be served a traditional dish if you ever get invited for dinner at a British family's home!

    Most people have flown a kite or have seen one ride and dip in strong spring wind. Not so many people know that kites were first made in China thousands of years ago. The ancient Chinese were making and flying kites even before they were writing.

    A long time ago, the Chinese made kites to use in wars. They would fly these war kites in the dark. The kites were fixed so that they made strange sounds. Men who were at war with them would hear these sounds and run away. They thought those strange sounds were made by gods in the sky.

    The ancient Chinese also flew kites to bring good luck and to make their crops grow rich and tall. Sometimes they tied long strings and hooks to their kites. Then they would fly the kites over water, letting the hooks hang down to catch fish.

    The Chinese use sticks, strings and paper for their kites. Some of these kites look like animals or trees. Others look like birds or houses.

    A thrilling polar competition between two adventurers to cross Antarctica alone, unsupported and unassisted had a happy ending with both explorers achieving the unprecedented feat (功绩). American professional athlete Colin O'Brady and British Army Captain Louis Rudd set off a mile apart at the same time on November 3, 2018, from the Atlantic coast with the aim to become the first person to ski across the remote continent alone.

    Louis Rudd maintained the lead at first. However, O'Brady caught up with Rudd on November10 and never let the British man get close to him again. O'Brady was the first to conquer the 930 mile icy land, arriving at the Ross Ice Shelf on the Pacific coast by way of the South Pole on December 26, 2018. The 33-year-old spent 54 days skiing the world's coldest continent while pulling a 300-pound sled(雪橇) with supplies.

    Instead of leaving the harsh environment after completing the historic adventure, the explorer set up a tent on the world's largest ice sheet and waited patiently for Rudd to complete the great undertaking. On December 29, just three days after O'Brady arrived, the British explorer finished his adventure, becoming the world's second person to complete the solo crossing of the frozen continent.

Rudd was not disappointed at being second since he never considered it to be a     "race". Besides, the 49-year-old British Army Captain had a more selfless motive for attempting the feat. He was doing it in memory of his friend Henry Worsley, who had introduced him to polar exploration. The disaster happened while Worsley was trying to cross the continent alone in 2016. Rudd said, "I didn't want to get drawn into a race. All that mattered to me was that I completed it, and that I skied solo and unsupported, carrying the flag with Henry's name on it."

    After spending a few days camping 10 feet away from each other, the two adventurers were picked up by a helicopter to the South Pole scientific research station.

    I've come back to check on a baby. Just after dusk I'm in a car down a muddy road in the rain, past rows of shackled(戴镣的) elephants, their trunks swinging. I was here five hours before， when the sun was high and hot and tourists were on elephants' backs.

    Walking now, I can barely see the path in the glow of my phone's flashlight. When the wooden fence post stops me short, I point my light down and follow a current of rainwater across the concrete floor until it washes up against three large, gray feet. A fourth foot twisted above the surface, tied tightly by a short chain and choked by ring of metal spikes(尖刺) When the elephant tires and puts her foot down， the spikes press deeper into her ankle.

    Meena is four years and two months old, still a child as elephants go. Khammon Kongkhaw, her caretaker, told me earlier that Meena wears the spiked chain because she tends to kick. Kongkhaw has been responsible for Meena here at Maetaman Elephant Adventure, near Chiang Mai, in northern Thailand, since she was 11 months old. He said he keeps her on the spiked chain only during the day and takes it off at night. But it's night now.

    I ask Jin Laoshen, the Maetaman worker accompany in me on this nighttime visit, why her chain is still on. He says he doesn't know.

    Mactaman is one of many animal attractions in and around tourist-crowded Chiang Mai. Meena's life is set to follow the same track as many of the roughly 3, 800 captive(被捕获的) elephants in Thailand. When Meena is too old or sick to give rides-maybe at 55, maybe at 75she'll die. If she's lucky, she'll get a few years of retirement. She'll spend most of her life on a chain.
