WHAT can help you make a fortune in the future? Graduating from a top university might not be enough. A new study from the University of Essex in Britain has shown that the more friends you have in school, the more money you'll earn later.

    The idea that popularity could have a serious influence on one's earning potential shouldn't come as too much of a surprise. The researchers noted that if you want to get ahead in life, social skills and networking are easily as powerful as talent and hard work.

    “If a person has lots of friends, it means that he or she has the ability to get along with others in all kinds of different situations,” said Xu Yanchun, 17, from Nantou High School in Shenzhen, who totally agreed with the recent finding. “Also, friends always help each other. They not only create wider social circles for you but lift your mood when you are occasionally in low spirits,” said Xu. She believed that all this helps you “earn a higher salary.”

    Maybe that's why some people think the younger generations are in the age of Friendalholism (交友狂症). A woman even complained that the networking website Facebook's 5,000-friend limit was too low for her large reserve of social contacts.

    But what does a friend mean? Should friends be regarded as a form of currency?

    “Call me uncool, but I think of a friend as an actual person with whom I have an actual history and whom I enjoy actually seeing. It seems, however, that this is no longer the definition of friend”, said Meghan Daum, who works with The Los Angeles Times in the US.

    Daum dislikes the idea that quantity trumps quality in the age of Friendaholism. She thought the idea of friendship, at least among the growing population of Internet social networkers, was to get as many of not-really-friends as possible. For example, a friend might be someone you might know personally but who could just as easily be the friend of a friend of some other Facebook friend you don't actually know. Although she agreed that social ties grease (润滑) the wheels of life, she also warned. “Too bad one thing money can't buy is a real friend.”

    It was a cold winter day. A woman drove up to the Rainbow Bridge tollbooth (收费站). “I'm paying for myself, and for the six cars behind me,” she said with a smile, handing over seven tickets. One after another, the next six drivers arriving at the tollbooth were informed, “Some lady up ahead already paid your fare.”

    It turned out that the woman, Natalie Smith, had read something on a friend's refrigerator: “Practice random(随意的，随机的) kindness and aimless acts of beauty.” The phrase impressed her so much that she copied it down.

    Judy Foreman spotted the same phrase on a warehouse wall far away from home. When it stayed on her mind for days, she gave up and drove all the way back to copy it down. “I thought it was beautiful,” she said, explaining why she'd taken to writing it at the bottom of all her letters, “like a message from above.” Her husband, Frank, liked the phrase so much that he put it up on the classroom wall for his students, one of whom was the daughter of Alice Johnson, a local news reporter. Alice put it in the newspaper, admitting that though she liked it, she didn't know where it came from or what it really meant.

    Two days later, Alice got a call from Anne Herbert, a woman living in Marin. It was in a restaurant that Anne wrote the phrase down on a piece of paper, after turning it around in her mind for days.

    “Here's the idea,” Anne says. “Anything you think there should be more of, do it randomly.” Her fantasies (imagination) include painting the classrooms of poor schools, leaving hot meals on kitchen tables in the poor part of town, and giving money secretly to a proud old lady. Anne says, “Kindness can build on itself as much as violence can.”

    The acts of random kindness spread. If you were one of those drivers who found your fare paid, who knows what you might have been inspired to do for someone else later. Like all great events, kindness begins slowly, with every single act. Let it be yours!

    Dolphin or not a dolphin? That is the question! You see, there are several types of dolphins. Some are saltwater dolphins while others are river dolphins.

    "What are the 32 types of dolphins?" When people are asking the question, they are actually referring to the saltwater dolphins in oceans and seas. The river dolphins living in fresh water are not included in these species. But what would be the answer in this case if we ask. "Dolphin or not a dolphin?" The answer would obviously be yes. River dolphins still belong to the dolphin family.

    Among the 32 types of dolphins do not actually wear the word "dolphin" in their names, such as the tucuxi, while others actually have the word "whale" as part of their names even if they are not whales but in fact, belong to the dolphin family, for example, the melon-headed whale and the killer whale. So what would be the answer to the question "Dolphin or not a dolphin?" in these cases? It would be yes. All these species do belong to the dolphin family.

    Another question that people ask is. "Are the sea animals that perform at aquariums(水族馆)all dolphins?" So ,it always seems to come back to the question, "Dolphin or not a dolphin?" Well the answer is no in this case. The sea animals that perform there are not all dolphins. The beluga which people tend to think belong to the dolphin family because they show what seems like a smile, like most dolphins, are in fact a species of the whale family.

    Now that you read these facts about dolphins, you probably realize that certain sea animals may appear to be part of the dolphin species and that others seem to be part of the whale family but in either case, it is not obvious and can be surprising when you identify a sea animal as being a dolphin or not a dolphin. That is the question ！

    London's newest skyscraper(摩天大楼)is called the Shard and it cost about 430 million pounds to build. At a height of almost 310 meters, it is the tallest building in Europe. The Shard has completely changed the appearance of London. However, not everyone thinks that it is a change for the better.

    The Shard was designed by the famous Italian architect Renzo Piano. When he began designing the Shard for London, Piano wanted a very tall building that looked like a spire(尖顶). The sides of the building aren't regular. So the building has an unusual shape. And that is how the building got the name：the Shard. Piano says that the spire shape of the Shard is part of a great London tradition. The shape reminds him of the spires of the churches of London or the tall masts(桅杆)of the ships that were once on the river Thames.

    The Shard has 87 floors. At the moment the building is empty, but finally there will be a five-star hotel. There will also be top quality restaurants, apartments and offices.

    Before building work began, a lot of people didn't want the Shard though the plans were approved. Now they are still unhappy about the Shard. Some critics say that such a tall skyscraper might be good in a city like New York, but not in London. They say that the best thing about the Shard is its shape. But that is the only thing. There is no decoration, only flat surfaces. The Egyptians(埃及人)did that 4, 500 years ago.

    Other critics don't like what the Shard seems to represent. They say that the Shard shows how London is becoming more unequal. Only very rich people can afford to buy the expensive apartments and stay in the hotel. But the people living near the Shard are among the poorest in London. So the Shard seems a symbol of the division(分化)in society between the very rich and the poor.

    The Shard now dominates the London skyline. It is not certain, however, that ordinary London citizens will ever accept it as a valuable addition to the city.

    In the middle of the 19th century，a fever dream of riches beyond measure drew countless explorers west to the mountains of central California. Although the gold rush ended up being a bust for many who sought a fortune，some of those explorers discovered a natural treasure that would draw permanent settlers to Yosemite Valley in the following decade.

    Vast wilderness，beautiful mountains，countless waterfalls，and abundant wildlife drew Native Americans to Yosemite roughly 10，000 years ago. The first non-native tourists arrived in the mid-1850s after reports from gold seekers told of an area of breathtaking beauty that no words were able to describe.

    Fortunately，some of Yosemite's earliest settlers recognized that Yosemite's natural beauty and resources needed to be preserved for future generations. In the midst of the Civil War，President Abraham Lincoln signed a grant to protect Yosemite permanently，thus making it the nation's first land to be dedicated to recreation and setting the stage for what would become the national park system.

    One of Yosemite's earliest ambassadors was Scottish-American naturalist and writer John Muir. After living in Yosemite for a few years，he helped define its proposed boundaries. He also wrote articles that helped lead to its official title as a National Park in 1890.He later co-founded the Sierra Club in 1892 to advocate for its continued preservation and protection.

    Located on the western slope of the Sierra Nevada mountain range in central California，Yosemite National Park runs across nearly 748，000 acres，almost 95％of which is wilderness. Around four million visitors come to Yosemite each year to camp，hike its miles of trails，climb its rock formations，and photograph its impressive sights. Are you ready to visit Yosemite National Park? Which of Yosemite's sights would you most like to experience?

    A 3-year-old boy who was lost in the woods for two days is now safe at home with his family. But Casey Hathaway told his rescuers that he was not alone in the rainy, freezing cold woods. He said he was with a friend — a bear.

    The child went missing on January 22. He was playing with friends at his grandmother's house in the southern state of North Carolina. When the other children returned home but Casey did not, the family searched the area for almost an hour before calling the police. Police formed a search and rescue team to look for the young boy in the nearby woods. But two days went by and still — no Casey.

    Then on January 24, someone called the police saying he heard a child crying in the woods. Police followed up on the information and found Casey at about 9:30 that night. They pulled him out of some briar. He was in good health. Casey told the rescuers that he had hung out with a black bear for two days, a bear he called his "friend".

    Sheriff Chip Hughes spoke with reporters from several news agencies. He said Casey did not say how he was able to survive in the woods for three days in the cold, rainy weather. However, the sheriff said, "He did say he had a friend in the woods that was a bear that was with him."

    Hundreds of people helped in the search and rescue efforts, including some 600 volunteers, federal police and members of the military. Officer Hughes told reporters that at no point did he think Casey had been kidnapped.

    His mother Brittany Hathaway talked with reporters from a local news agency and thanked everyone who joined the search for her son. "We just want to tell everybody that we're very thankful that you took the time out to search for Casey and prayed for him, and he's good," said his mother. "He is good, he is up and talking. He's already asked to watch Netflix. So, he's good …"
