Augusto Esquivel is a sculptor who, in his own words, is “crazy with comparisons of reality and potential and the balance between them.” Perhaps the best example of what he's talking about are his most famous creations: the suspended(悬挂的) button sculptures.

    Made entirely from buttons hanging on various lengths of string, Esquivel's sculptures are made to look like common objects: a piano, a gumball machine, and even a toilet. If it wasn't for the clear string hanging above, these objects, these sculptures, would look solid, yet you can put your hands right through them. The process starts with him deciding on a subject and setting the acrylic （丙烯酸树脂）from where the buttons are being suspended. He buys buttons of different shapes and sizes, paints them with spray paint, and carefully hangs them. After that, it's a manner of hanging each individual button, which takes a lot of time. For his piano, for example, he individually hung over 60 pounds worth of tiny buttons.

    Esquivel's sculptures, while mostly housed inside art galleries, perfectly capture one of the main principles of street art: something that is eye-catching and something that invites interaction. Often the best sculptures outside the art galleries aren't the ones behind guards and fencing, but the ones people can go right up to and touch. In Vancouver, a series of laughing old men are attracting people for pictures and to just generally hang around, but the people who simply walk by and see the sculptures almost always leave with a smile on their face. That's good street art: it draws the viewer in rather than relying on a gallery to draw in an audience and point them to certain pieces.

    Esquivel's art is not only a presentation of talent, something that mentions larger philosophical questions, like the ones he stated above, but also just the right combination of interesting idea and painstaking work. One can look at his work in a critical way, or simply appreciate his idea and execution(艺术品的制作).

    We face problems in our everyday life. They can be social problems, relationship problems, or problems at work. Don't worry{#blank#}1{#/blank#}

    Be aware of problem

    First of all, it is important to know and understand the problem clearly{#blank#}2{#/blank#}Following questions like why, what, how, when, where and who will take you to the root cause of the problem.

    Analyze the problem.

    Analyzing the problem will give you time to think of a proper solution{#blank#}3{#/blank#}They can be diagrams, or lists, etc.

    {#blank#}4{#/blank#}

    Leave out the information that isn't required for the solving of the problem. You need to be accurate with the details. Keeping the unrelated information can sometimes complicate the simple problem as we don't notice the important information.

    Carry out the solution.

    Putting the solution into effect in a correct way to get the result expected is important while solving a problem{#blank#}5{#/blank#}Being ready with alternatives is also important in case a solution works only halfway.

A. Remove unrelated information.

B. You can use various tools to study the problem.

C. Use yes or no questions to get better information.

D. As long as you are breathing, you can solve problems.

E. Knowing the problem means solving half the problem itself

F Spend a little time analyzing the problem and most on the solution.

G. You need be creative while carrying out a solution in case some other problems arise.

    People who play computer games to train their brains might as well be playing Super Mario, new research suggests.

    In a six-week study, experts found people who played online games designed to improve their cognitive(认知的) skills didn't get any smarter.

    More than 8,600 people aged 18 to 60 were asked to play online brain games designed by the researchers to improve their memory, reasoning and other skills, for at least 10 minutes a day, three times a week.

    They were compared to more than 2,700 people who didn't play any brain games, but spent a similar amount of time surfing the Internet. All participants were given an "IQ test" before and after the experiment.

    Researchers said the people who did the brain training didn't do any better on the test after six weeks than people who had simply been on the Internet.

    "If you're(playing these games) because they're fun, that's absolutely fine," said Adrian Owen, assistant director at Britain's Medical Research Council. "But if you're expecting these games to improve your IQ, our data suggests this isn't the case."

    Computer games that are supposed to improve memory, reasoning and other cognitive skills are played by millions of people worldwide, though few studies have examined if the games work.

    "There is precious little evidence to suggest the skills used in these games transfer to the real world," said Art Kramer, a professor of psychology at the University of Illinois, US.

    Instead of playing brain games, Kramer said people would be better off getting some exercise. He said physical activity can help produce new brain cells.

    Other experts said brain games might be useful, but only if they weren't fun.

    "If you set the level for these games to a very high level where you don't get the answers very often and it really annoys you, then it may be useful," said Philip Adey, a professor of psychology at King's College in London.

    If people are enjoying the brain games, Adey said they probably aren't being challenged and might as well be playing a regular video game.

    He said people should consider learning a new language or sport if they really want to improve their brain power. "To stimulate(激发) the intellect, you need a real challenge," Adey said, "Getting smart is hard work."

New Lives for Old Phones

    When a new mobile phone starts to be sold in stores, many people rush out to buy one. We all want the newest, latest thing.{#blank#}1{#/blank#}

    Mike Townsend works at Total Recall, a mobile phone recycling company. "Don't throw your old phone away. {#blank#}2{#/blank#}If you throw it away, it goes with other rubbish to become landfill. In other words, it is put in a big hole in the ground-and it becomes a big problem," he says.

    Mobile phones contain some poisonous materials. If your phone goes to a landfill, these poisonous materials can get out and get into the water under the ground. That's the water we need to drink or water goes into rivers or the ocean. {#blank#}3{#/blank#} That's a lot of landfill and a lot of poisonous materials.

    "At Total Recall, we separate the old phones into pieces. Most of the materials in the mobile phones can be recycled and used again.{#blank#}4{#/blank#} For example, phone batteries contain nickel and cadmium. The nickel is used to make steel, and the cadmium can be used to make new batteries," explains Mike.

    "{#blank#}5{#/blank#}You can usually just take it into a mobile phone shop and they will send it to us," says Mike.

    So before you throw that old mobile phone away, use it one last time: search for a recycler near you and give them a call.

A. Send it to us and we'll recycle it.

B. Recycling your old phone is easy.

C. How much is your old mobile phone worth?

D. But what should we do with our old mobile phones?

E. Millions of mobile phones are thrown away every year.

F. We take apart the old phones and they are used to make new products.

G. Recycling materials helps keep the environment greener and cleaner.

    Some of the world's biggest companies—Apple, Amazon, Facebook—didn't exist 30 years ago. So what firms are we working for in 2050? That's a question put forward by historian Yuval Noah Harari in his new book "21 Lessons for the 21st Century".

    He argues that because technology is changing so fast, it's one of the first times in human history when we don't know what jobs will look like in the coming three decades." So the best bet is to focus on emotional intelligence（EQ）," he said. "Information is the last thing the kids need. They have too much of it."

    In this book, he focuses on the various challenges facing us today. As he writes in the book's introduction: "What are today's greatest challenges? What should we pay attention to? What should we teach our kids?" One area where these questions crop up is artificial intelligence（AI）Harari believes that AI will completely affect the job market for the next generation of workers.

    His first two books—"Sapiens" and "Homo Deus"—became international bestsellers, selling more than 12 million copies worldwide. They were praised by the likes of Mark Zuckerberg, Barack Obama and Bill Gates. Harari's books, about the past and future of humanity, attract a great number of fans. Fellow Israeli, actress Natalie Portman, is a fan. So is American R&B star Janelle Monae.

    As for Bill Gates, he might be Harari's biggest fan. So when the New York Times asked him to review Harari's latest books, he jumped at the opportunity. "All the three books wrestle with some version of the same question: What will give our lives meaning in the decades and centuries ahead?" Gates wrote in his review. "So far, human history has been driven by a desire to live longer, healthier, happier lives. If science is eventually able to give that dream to most people, and large numbers of people no longer need to work, what reason will we have to get up in the morning?"

All students are expected to read and learn the School Rules. These rules aim to make each student aware of the value of self-control, orderliness and the need to develop a sense of responsibility for their own behavior and for the larger community of which they are a part.

Dress Regulations

The School expects its students to wear their full school uniform correctly and with pride. It is our expectation that uniform and shoes will be clean and in good repair. Boys' hair should be combed and of an acceptable length (not over the collar, ears or eyes), with no artificial coloring. Girls' hair should be of a natural color. Shoulder-length hair must be tied back.

Absence, Illness and Punctuality

All students must be at school on time. If late, the student must sign in the late book in the General Office. Parents are asked to inform the school if their child is absent by 8:30 am on the day of absence. A written note from a parent explaining the absence MUST be provided to the General Office the day after return.

Should a student be ill during school hours he is to go straight to the School Medical Center. The sister will then take appropriate action.

Safety

◆ Proper behavior is expected within and around buildings and on the sporting field at all times.

◆ Students are not to enter laboratories, language rooms, the Technics and music rooms until invited to do so by teachers.

◆ The riding of bicycles or skateboards is prohibited along the front drive. Students riding bicycles must wear an approved bicycle helmet.

◆ No knives, explosives or dangerous materials may be brought into the school or boarding houses.

◆ Students are forbidden to interfere with fire safety equipment. An automatic fine will be imposed if this occurs.
