John was part of my childhood growing up in the 1970s and a link to sunny, fun-filled days spent on the beach at Bangor in Northern Ireland where we went for our summer holidays. To many, he was a mystery. Every afternoon John would wander to the end of the pier (码头) where he fed the seagulls and delighted in the sound of their excited cries as they flew around his head.

    Often I asked my family questions regarding John. Eventually I gave up as no one could tell me anything about him. As I grew up, my visits to the beach became less frequent, and my memories of John buried in a child's imagination.

    Last year memories came flooding back as I walked along the coastline, where I noticed a lady feeding the seagulls on the pier, and I decided to introduce myself. Then I came to know that the lady was John's daughter, and after John left this world she carried out the ritual (惯例), which had held such importance for her father.

    In some strange way I felt we shared a bond, each needing to remember. In return, Lucy told me of John's life, his days in the British Navy (海军) during World War I and how he almost lost hope when his ship was attacked by a German U-boat in the North Sea and he found himself in a lifeboat with five others.

    Close to death, he thought he heard the sound of wings. He put up his hands, only to catch a seagull that had landed on the side of the boat. The seagull saved the lives of the six men as it was used to catch fish, which kept them alive until they reached land. This period of John's life was one he never talked about. But the ritual he first performed as a young man remained a part of him until he died.

    Now I visit Lucy as often as I can, just to chat or very often walk along the beach to the pier end. We enjoy the comfortable silence, each lost in special memories.

    Welcome to Orlando! It has a host of attractions and activities. Ready to join the party and plan a visit to O-Town? Just print out our must-see list.

    Universal Orlando's Islands of Adventure

And if you enjoy a side of fear with your water-park fun, be sure to check out Ihu's Breakaway Falls. This towering slide is not for the weak heart. The less adventurous will still find plenty of fun playing from one big wave pool to another or flowing down the lazy river through a world of unusual fish. You can also watch dolphins underwater. (407-351-3600)

    Warbird Adventures

    Warbird Adventures offers you the opportunity to fly like a hero in World War II in the North American Aviation T-6 Texan(also known as the Harvard). Flights last from 15 minutes to an hour. A visit to the nearby Kissimmee Air Museum is a wonderful way to round out the experience. (407-870-7366)

    I was at my parent's dinner table. Before me was a worn journal of thin and discolored pages. It was my grandfather's journal and now belonged to my father. My grandfather had passed away in the months leading up to my birth. I never got to visit the places he had frequently and people who had been a part of his life's journey.

    I was now about to enter his world, through the words he had left behind. Within minutes, I was attracted by the power of the written words. In the magical script before me, I was transported to another age when food was an everyday art, planned, prepared and enjoyed in the company of others, and a time when people had the heart to pause，their own lives to embrace (拥抱）each other's struggles. All this was conveyed to me in the beauty of the words that flowed together to connect with the writer's mind and understand the world they lived in.

    That kind of writing seems to be lost on us today. We have gotten used to writing in bite-sized pieces for a public looking for entertainment, and hungry for information. No wonder, there are nearly 200 million bloggers on the Internet and a new blog is created somewhere in the world every half a second. Instead of adding to our collective wisdom, most of these writings reflect the superficiality (肤浅)and impatience of our day and age.

    This not only robs us of the skill of writing impressive essays, it also prevents us from exploring what is truly important. Writing humbles us in a way that is vital for our character growth, by reminding us about the limits of the self and our appropriate place in the vast flow of life. Writing frees us by helping us explore the unknown so that we truly open up to the magic of the world around us. I saw all of this in the writing s of my grandfather. And I've seen it again and again in the writings of the greatest thinkers of humanity. Their writings reflect deep thought on issues of human importance.

    The hit movie Notting Hill（诺丁山）begins with a famous scene. Hugh Grant bumps into Julia Roberts and spills orange juice all over her. After the collision, Grant repeatedly says, “I'm so sorry. I'm so sorry.”

    His actions in this scene are very British. If Roberts' character were from the Britain, than she would probably apologize repeatedly as well – even if the crash were not her fault. But this doesn't happen in the movie, as Roberts is from the US.

    A report in The Telegraph once said that three quarters of British people apologize when they bump into someone in the street – regardless of whether they are responsible or not. In fact, Britons use “sorry” in many situations. For example, if they mishear someone, they say “Sorry?” The person they are talking to will also apologize by replying, “No, I am sorry!” This can go on for up to five minutes as they compete over who is the most sorry.

    Why are Britons so sorry? Mark Tyrell, a psychology writer in the UK, thinks that their apologetic tendencies are rooted in British class system. “We say sorry because historically the new middle class in Britain had to apologize for not being the working class, but also for really being the upper class.” Another theory is that they apologize to avoid conflicts. For example, if they bump into someone, he might get angry. To avoid this, they instantly say “Sorry!”

    True manners are about being considerate, and today's constant use of apologizing shows that we are perhaps not as thoughtful as we once were. The word “sorry” has lost some of its meaning.

    Do you see my point? Sorry, it might just be a British thing.

    There's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn't stopping there.

     Food production

    With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that — it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to "re-create forms and pieces" of food that are "exactly the same," freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

    Sustainability(可持续性)

    The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids (水解胶体) from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.

    Nutrition

    Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."

    Challenges

    Despite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.
