Best friends may be priceless but the cost of keeping the relationship alive is £23,870.

    According to a study, a BFF (best friends forever) does not come cheap with devoted friends spending £4,679 on birthday presents alone over a lifetime. And while it costs nothing to be a shoulder to cry on, big-hearted Britons go the extra mile and spend £168 on pick-me-ups(提神物品) to get their mate through a rocky patch (艰难时刻)like the breakup of a relationship.

    There's a further £242 spent on presents to show how much they mean from gifts bought on holiday to treats for no reason. And distance does not break up a close friendship as BFFs spend a whopping(巨大的) £18,000 on travel to see each other despite being miles apart because of university, jobs and marriage.

    The study by cashback site TopCashBack found on average BEFs who marry can expect £431 spent on them and a further £283 on gifts when they have children. And they can rely on their pals to help out when they move houses as they will obtain £127 worth of housewarming presents and takeaways(a kind of food).

    The survey based on a friendship lasting 40 years found more than eight in ten adults with a BFF felt their friendships were worth every penny.

    TopCashback spokesperson Natasha Smith said: “Those friendships which stand the test of time are often the most important in our lives. However, they come at a cost. From train tickets once a month to flights and a new dress for a wedding on the Italian coast, the price paid for having a best mate can soon add up. But when we asked people to compare their friendship with the financial investment(投资), only 14% thought their friendship was equal to their investment with the vast majority thinking it was worth more."

     When Regina Spektor moved to the Bronx from Russia as a young child of 9, she could speak no English and her family was so poor that they could afford nothing. Yet she carried with her a love of the piano and music.

     "For me, the thing that I loved the most was playing the piano, so when we left Russia I was so afraid I would forget how to play and I would just find a little table and play my pieces," she told "When you spend your life doing something like playing the piano and then you take that away, it's so surreal."(离奇的)

     Her father, Ilya Spektor, said that, little by little, the family saved enough money to afford their first apartment.

     "I was a photographer and, in six weeks, I found my first job in a big photo lab in Manhattan," he said. On the subway one day, Ilya Spektor spotted a man carrying a violin case. The man also seemed to have an Eastern European accent. A conversation led to a visit and, eventually, Regina Spektor was introduced to Sonia Vargas, a piano teacher. She was a well-known professor who taught piano, took Spektor under her wing and trained her for years, at no cost. "I remember talking to Sonia," Spektor said. "She said that when a student is ready, a teacher appears. So she said that I must have been ready to study piano, and so that's why she came into my life."

     "Immediately, how she played," Vargas said. "You can tell the sound. The sound tell you whether the person loves the instrument, loves the music."

     Much later, while playing her own music and selling a CD that she'd created, Regina Spektor caught the attention of a music producer. The rest is history, complete with concerts around the world and performance in front of the Obamas at the White House.

Regina Spektor greatly appreciated her parents, piano teachers and friends for helping her become the musician she is. “I love the idea that if you're walking toward the world, the world will take some steps towards you,” she said.

    Daniel was born in New Orleans, LA., in 1962, slow to walk and talk, and short. He was the tiniest in his class, but he developed a warm, outgoing nature and was popular with his peers(同龄人). And he became skillful at sports.

    Baseball gave him his earliest challenge. He was an excellent players in Little League. At graduation, the coach named Daniel the team's most valuable player.

    His finest hour, though, came at a school science meeting. He entered an exhibit explaining how the circulatory system works. It was traditional, especially compared to（与…相比）the modern, computerized, blinking-light models entered by other students. My wife, Sara, felt embarrassed for him.

    It turned out that the other kids had made their exhibits. As the judges went on their rounds, they found that these other kids couldn't answer their questions. Daniel answered every one. When the judges awarded the Albert Einstein Plague for the best exhibit, they gave it to him.

    By the time Daniel left for college he stood six feet tall and weighed 170 pounds. He was in superb condition, but he quit baseball for English literature. I was sorry that he would not develop his athletic talent, but proud that he had made such a satisfactory decision.

    One day I told Daniel that the great failing in my life had been that I didn't take a year or two off to travel when I finished college. This is the best way, to my way of thinking, to broaden oneself. Once I had married and begun working, I found that the dream of living in another culture had disappeared. Daniel thought about this. After graduation, he worked as a waiter at college, a bike messenger and a house painter. With the money he earned, he had enough to go to Paris.

    The night before he was to leave, I tossed in bed. I was trying to figure out something to say. Nothing came to mind. Maybe, I thought, it wasn't necessary to say anything.

    Charity Cycling UK recently launched a campaign to raise awareness of dooring after discovering that many people don't know what it is. Dooring is when a driver or passenger opens the door into another road user—typically cyclist—without looking for other road users.

    Cycling UK chief executive Paul Tuohy told Gloucestershire Live: “Some people seem to see car dooring as a bit of a joke, but it's not and can have serious consequences. Cycling UK wants to see great awareness made about the dangers of opening your car door carelessly, and people to be encouraged to look before they open.”

    The charity says 2,009 of the 3,000 injuries were sustained by cyclists, resulting in five fatalities but says this might not be the full extent of the danger.

    Cycling UK says not all car dooring incidents will be attended by police, so the charity has written to transport minister Jesse Norman calling for a public awareness campaign urging all car occupants, not just drivers, to look before opening vehicle doors. One of the ways the charity suggests is the “Dutch reach”, where people leaving a vehicle reach over and use the non-door side hand to open the door.

    Cycling UK also suggests harsher laws and advice on safer road positioning for people who cycle.

    Mr. Tuohy said: “In the Netherlands they are known for practicing a method, known sometimes as the 'Dutch reach', which we think could be successfully encouraged in the UK.”

    “Cycling UK has written to the Department for Transport asking them to look into this, and highlight the dangers of 'car dooring' through a public awareness THINK style campaign.”

    If you're really concerned about opening a door into the path of a cyclist coming behind you, consider using what's known as the “Dutch reach” to open the door. That will naturally turn you in your seat and give you a much better view of what's coming up alongside in the car.

    In earliest times, men considered lightning to be one of the great mysteries (神秘的事物)of nature. Some ancient peoples believed that lightning and thunder were the weapons (武器) of the gods.

    In reality, lightning is a flow of electricity formed high above the earth. A single flash of lightning 1.6 kilometres long has enough electricity to light one million light bulbs (灯泡).

    The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752. In the same year he also built the first lightning rod (避雷针). This device (装置物) protects buildings from being damaged by lightning.

    Modern science has discovered that one stroke (闪击) of lightning has a voltage (电压) of more than 15 million volts (伏特). A flash of lightning between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second.

    Scientists judge that there are about 2,000 million flashes of lightning per year. Lightning hits the Empire State Building in New York City 30 to 48 times a year. In the United States alone it kills an average (平均数) of one person every day.

    The safest place to be in case of an electrical storm is in a closed car. Outside, one should go to low ground and not get under tress. Also, one should stay out of water and away from metal fences. Inside a house, people should avoid open doorways and windows and not touch wires or metal things.

    With lightning, it is better to be safe than sorry?
