Welcome to one of the largest collections of footwear（鞋类）in the world that will make you green with envy. Here at the Footwear Museum you can see exhibits（展品）from all over the world. You can find out about shoes worn by everyone from the Ancient Egyptians to pop stars.

    Are you scared about moving up to senior high school?It can be a new experience,but you shouldn't worry.We've put together a guide on how to survive the first week.

    You're not alone

    Remember everybody else in your year is in the same boat.They may not realize it,but they're just as nervous as you are.Moving to senior high is an opportunity,not a problem.Things are different and all you need to do is be polite and learn the new rules.

    Teachers are ready to help!

    If you're unsure what to do or are worried about anything then you had better ask for help.Teachers are probably the best people to turn to as they're experienced in helping new students.Some senior high schools also have a “friends system”.If your school has this,then you will be paired with an older student.They will look out for you and help you if you have any problems or questions.

    All change

    There are lots of differences between junior high school and senior high school.You'll have a homework diary or a student planner.You will have your lessons with different teachers in different rooms.You will have homework for different subjects on different days,so make sure you get organized.Make sure you have a copy of your school timetable written down so you know which rooms your classes are in and on which days you will have your different subjects.

Other points

    If you've got an older brother or sister at the school then ask them for advice.

    Be yourself! It sounds simple,but people will know you much better if you just act naturally.

    Having early nights makes a difference and you'll find it easier to get up in the morning!

    Author Norman Mailer published an essay in which he declared the graffiti(涂鸦) of the New York subway to be "The Great Art of the 70s". But what happened to the artists and why is there no subway graffiti any more?

    "It started with someone just writing their name — someone saw that, and added on to it," recalls New York graffiti artist Nicer, born Hector Nazario. "Letters going in front of letters, coming back through a letter, behind a letter, going across a letter... the subways became our playground," adds Riff170.

    New York in 1974 was a city in crisis. The Mayor, Abe Beame, slashed the city's budget in a bid to stave off bankruptcy(破产), which meant laying off school teachers, police officers and subway staff.

    "They were taking the money from the schools, there was a lot of corruption here, in this community, and so they took the after-school programmes away, and there was no outlets for this. So the outlet became our city," says Bronx-born designer Eric Orr.

    "It was like an explosion. The graffiti explosion. All of a sudden it took over the whole city. I don't know what happened, but overnight in the early 70s it was from no graffiti to all graffiti," says another former artist, Flint Gennari.

    Eric Felisbret, author and former graffiti artist, says graffiti culture was in a way a product of the civil rights movement. "It was never political," he says, "but many people were brought up with that, and to express yourself by breaking the law became a natural process for them."

    The graffiti pioneers came from all races, however. "There were writers that were African American, Latino - Puerto Rico, Dominican, Cuban - Jewish, Asian, and it became one unit — one family," says another graffiti pioneer, Roberto Gualtieri.

    Prof Gregory Snyder, sociologist and author of Graffiti Lives, says: "For lots of people, graffiti is ugly, vandalistic, and I'm not denying that. It's vandalism... now, oftentimes it's very clever vandalism. It can be written on a dumpster, like a garbage bin, and if someone's attempting to make a garbage bin look a little prettier maybe that's not the worst thing in the world." Although Mailer was not alone in welcoming the flowering of creativity, the authorities hated it, as did many passengers.

    So when Mayor Ed Koch took office, he was determined to clean up the city and set about targeting graffiti.

    "I remember in 1982 he brought everyone out to a train yard and there was a single train painted white," says former New York Daily News reporter Salvatore Arena. Trains were taken out of service and cleaned as soon as graffiti was spotted. Carriages were protected at night and the city agreed to ban the sale of spray cans.

    If in 1984 80% of subway carriages contained graffiti by May 1989 the network was graffiti-free. “Graffiti has gone through an evolution, and it will continue to evolve. It's now socially accepted in places where 20-30 years ago that would have been impossible. It's now showcased(展示) in certain museums —and let's say in another 30 years from now it may be hanging in the White House,” says Nicer.

    Nowadays painted graffiti is largely gone from the New York subway trains themselves and is seen instead on the walls and tunnels of the city. It has been replaced by scratchiti(刮擦艺术) created onto carriage windows using keys, knives. Unlike the vivid images of 40 years ago, these ghostly patterns are somehow easy to ignore. After all, graffiti has faded quietly into the background.

    Adults understand what it feels like to be flooded with objects. Why do we often assume that more is more when it comes to kids and their belongings? The good news is that I can help my own kids learn earlier than I did how to live more with less.

    I found the pre-holidays a good time to encourage young children to donate less-used things, and it worked. Because of our efforts, our daughter Georgia did decide to donate a large bag of toys to a little girl whose mother was unable to pay for her holiday due to illness. She chose to sell a few larger objects that were less often used when we promised to put the money into her school fund(基金）(our kindergarten daughter is serious about becoming a doctor)

    For weeks, I've been thinking of bigger, deeper questions: How do we make it a habit for them? And how do we train ourselves to help them live with, need, and use less? Yesterday, I sat with my son, Shepherd, determined to test my own theory on this. I decided to play with him with only one toy for as long as it would keep his interest. I expected that one toy would keep his attention for about five minutes, ten minutes, max. I chose a red rubber ball-simple, universally available. We passed it, he tried to put it in his mouth, he tried bouncing it, rolling it, sitting on it, throwing it. It was totally, completely enough for him. Before I knew it an hour had passed and it was time to move on to lunch.

    We both became absorbed in the simplicity of playing together. He had my full attention and I had his. My little experiment to find joy in a single object worked for both of us.

    As Artificial Intelligence(AI) becomes increasingly sophisticated(复杂的), there are growing concerns that robots could become a threat. This danger can be avoided, according to computer science Professor Stuart Russell, if we figure out how to turn human values into a programmable code.

    Russell argues that as robots take on more complicated tasks, it's necessary to translate our morals into AI language.

    For example, if a robot does chores around the house, you wouldn't want it to put the pet cat in the oven to make dinner for the hungry children. "You would want that robot preloaded with a good set of values," said Russell.

    Some robots are already programmed with basic human values. For example, mobile robots have been programmed to keep a comfortable distance from humans. Obviously there are cultural differences, but if you were talking to another person and they came up close in your personal space, you wouldn't think that's the kind of thing a properly brought-up person would do.

    It will be possible to create more sophisticated moral machines, if only we can find a way to set out human values as clear rules.

    Robots could also learn values from drawing patterns from large sets of data on human behaviour. They are dangerous only if programmers are careless.

    The biggest concern with robots going against human values is that human beings fail to so sufficient testing and they've produced a system that will break some kind of taboos(禁忌).

    One simple check would be to program a robot to check the correct course of action with a human when presented with an unusual situation.

    If the robot is unsure whether an animal is suitable for the microwave, it has the opportunity to stop, send out beeps(嘟嘟声), and ask for directions from a human. If we humans aren't quite sure about a decision, we go and ask somebody else.

    The most difficult step in programming values will be deciding exactly what we believe in moral, and how to create a set of ethical rules. But if we come up with an answer, robots could be good for humanity.
