Have you ever fancied sailing around the world or buying a holiday home in the Caribbean? Well, before you get too excited, it may help to find out if you have what it takes to become a billionaire.   

    We've all heard stories of school drop-outs who have made their fortune. Do they tend to be university graduates or self-made successful people? Are they married or single?

    Thanks to a recent analysis of people in Forbes（福布斯）Top 100 Billionaires List, we can now find out what they have in common. We know what percentage wear glasses and even how many are bald!

    If you are deciding whether or not to go to university, it may help you to know that 76% of the richest people in the world have a degree. According to this study, of those 76%, 47% have a bachelor's degree, 23% have a master's and 6% have a doctorate. Don't lose hope if you aren't very academic, though. It's worth noting that many of those on the list did not pass all their exams with flying colors. Microsoft founder Bill Gates dropped out of Harvard University after two years of study. And Chinese business magnate Jack Ma, failed his university entrance exams three times before going on to complete his degree and make his millions.

    Another interesting trend is that the world's richest people are much more likely to be married - only 12% of billionaires are unmarried. Finally, the percentage of billionaires who are bald is quite high – so don't worry if you're losing your hair.

    The most important thing to keep in mind when going into high school is to be yourself. Besides, I don't know what your middle school was like, but high school teachers will not care about things such as how much homework you already have in one night. It's best to just learn to deal with things and manage your time wisely so you can achieve everything you need to.

    I think almost every kid feels both nervous and excited before their first day. You will probably love it. I know I did. You should join some sports or activities that will make your high school experience more enjoyable. Good luck!

Eddie, Aged 20

    When I started high school I was really nervous too, especially since I had been homeschooled all through middle school and didn't really know anyone. I suppose the best advice would be to just relax. The first couple of days can be a little bit hard, but things will become easier before you know it.

    I'm not going to lie. The first day is kind of frightening（令人恐惧的）. But you'll get used to it. Don't be afraid of anyone; upperclassmen will pick on you more if you let them know you're afraid. Just take it easy. Making some friends and staying with them will greatly help you get used to high school quickly. After the first week it's really not bad at all. Don't worry.

    Every year, millions of people head to London's Trafalgar Square to see Nelson's Column, and the four lion statues that “guard” it. And last month, during the London Design Festival, a bright red lion sculpture was added to the collection.

    But this was more than just a statue: It had a large open mouth, with an LED screen inside it. At the same time, passersby could type in random words on a screen close to the lion, which were used to produce an AI-created poem. The most interesting part of the poems lies in their randomness, as the words that people choose to enter include many things, such as the time, the weather and their mood. In the daytime, the finished poem appeared on the LED screen, but at night, it was projected (投射) onto the lion's body and the famous Nelson's Column, in a 1ovely light display.

    Es Devlin, the sculpture's creator, was inspired by the history behind the four historic lion statues. Edwin Landseer, the designer of the lions, wanted them to look much more animated, but Queen Victoria refused his plan. This made Devlin wonder, "What if we could give a lion a poetic voice?" According to Devlin, although England has seen many poems about national identity in recent years, these works have been lacking imagination. "I wanted to make a piece that was poetic and collective" he told BBC News.

    After standing for almost 180 years, the purpose of Trafalgar Square has changed over the years. But thanks to the high-tech lion and its poetry, the square is standing the test of time.

    Russ Gremel, now 98 years old, decided it was time to donate $2 million to the Illinois Audubon Society, a charity to purchase nearly 400 acres of land for wildlife protection. Gremel was able to make this amazing donation because he purchased $1,000 worth of Walgreens stock seven decades ago whose value has grown recently.

    "A single man with no kids, Gremel has lived in the same Chicago house for 95 years, and has always lived simply", neighbor Patrick Falso told TODAY. Falso said he heard Gremel say many times the "money wasn't mine to begin with" and that he always intended to give it away.

    The Gremel Wildlife shelter was founded on June 4. Illinois Audubon Society president Jim Herkert said Gremel's donation was extremely generous. "It's allowing us to protect a really valuable and important possession and realize one of Gremel's wishes that we could find a place where people could come out and experience nature the way he did as a kid," Herkert told TODAY.

    After doing all this, this past weekend, Gremel adopted an old Chihuahua（吉娃娃犬）. Winnie the dog was picked up as a homeless dog several months ago. She suffered from a kind of cancer, which was treated—and all she needed was a loving home, which Colleen Collins, the founder of Perfect Pooches Adoption Agency, was determined to find.

    Gremel had lost his own beloved Chihuahua earlier this year. When he reached out to Collins about Winnie, she felt this could be a good match. That feeling grew when she brought Winnie to his house for a meet and greet, and Winnie was introduced not only to Gremel but also some of his friends and neighbors. One had brought over a lot of fresh strawberries; all said they'd be there to help out in any way needed.

    Most animals on land are known to us, but many living things underwater are not. Now let's get to know some of them.

    Sea cucumber

    Sea cucumber are strange animals living at the bottom of the sea. They wear brown or pale green coats with many sticks up. When summer comes, they stay deep to sleep because they are afraid of heat. And when it is autumn, they move to shallow (浅的) water and get their food.

    Pike

    The pike is a kind of freshwater fish. They are good swimmers and like swimming near boats, waiting to be fed. They have sharp teeth to catch fishes. When they are young, they live in groups. However, when they grow up, they prefer to live alone.

    Cuttlefish

    A cuttlefish can swim quite fast, so it is also called rocket (火箭) fish. It has eight arms and two feelers on its head, just around its mouth. It ejects ink (喷墨) when it is in danger. Its meat is delicious, and it is often the first choice for many people.

    Octopus

    An octopus has long arms, with which to catch food and protect itself. When it is sleeping, one or two of its arms are still on duty, keeping moving. Once it feels something dangerous, it can wake up at once to take action.

    College students may find a greener campus when they return to classes this fall. Some schools arc repairing older buildings and constructing new ones that arc better for the environment. Other steps include adding wind and solar energy systems and planting vegetable gardens.

    George Washington University（GW）is a private school with 200.000 students. The university has two gardens where students volunteer their time.

    Over the last ten years GW has developed projects in three main areas-climate, water and eco-systems. They have begun to create projects on the ground to address climate change, They are planning on becoming carbon-neutral（平衡的）and, in fact, reducing the footprint by forty percent by 2025, from creating solar hot-water systems on our rooftops to making our buildings much more energy efficient. The school also offers 140 different classes in sustainability （可持续性发展）and the environment.

    Mark Orlouski said. "We see numbers like less than 20% of school having a green building policy five years ago, and now upwards of 80% of schools having a policy, which states that their new buildings will be built in a green fashion.

    GW is located in the Foggy Bottom neighborhood of Washington. Some neighbors say that while GW is laying to be Friendlier to the environment, it could also be a better friend to the neighborhood. The school has expanded quickly and there have been tensions between students and local residents
