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.

    Scientists are using robots to study the health of waters in and around Venice, Italy. The robots are designed to act like fish, other underwater creatures and plants. The scientists are working with several universities and research centers as part of a group called subCULTron. The European Union gives money to the project as part of its Horizon 2020 program whose aim is to take great ideas from the lab to the market and support science and innovation (创新) in Europe. The scientists want to use the artificial intelligence of the robots to help humans understand what is happening under the water of the Venice lagoon (潟湖).

    SubCULTron, a collective artificial intelligence project, plans to create the biggest shoal (鱼群) of robot fish in the world. The project's aim is to improve knowledge of the seabed and try to turn human abilities into hi-tech items.

    Alexandre Campo, a computer scientist, says the scientists have looked at the way animals learn to work in groups to understand how robots can learn to work together. The subCULTron project wants its robots to learn to work together so they can watch out for changes and new problems in the water.

    One problem the researchers had in the beginning was how the robots would communicate with each other. Wi-Fi and GPS equipment don't work underwater. Instead，the robots can use sonar (声呐) and an electric field.

    Another problem was charging batteries. The robots come up to the water's surface and stay near a boat or a power station to charge without any electrical cables. Besides, how to be water- proof, especially for some key pads of the robots, was really tough. Fortunately, a special mixture has been created to be pinned on the robot, which successfully stands the test of water.

    The health state of the lagoon is pretty good. There are no industrial polluters, and the city now has a modem sewer (污水管) system. It's not like before when all the waste flushed directly into the water. The robots in Venice will continue their work until 2019. The subCULTron project hopes they develop into “an artificial society underneath the water surface” that serves “a human society above the water”.

    One of my all time favorite holiday destinations is the Gold Coast. With its beautiful beaches, mountain hinterland and theme parks, the variety from one location to another is fantastic! And it's also important that it's like a playground for my children.

    The Gold Coast certainly offers something for every member of our family. We all love heading down to the beach for an early morning swim or surf. The beaches feature some of the softest golden sand and pumping waves, making them ideal for surfing. Safety is important especially when I'm out with the kids, and I feel better knowing that lifeguards are continually on patrol（巡逻）. The long coast also offer the perfect setting for a leisurely walk at sunset-a favorite activity of mine.

    Then, of course, there's the bargain-hunting in the city's center. For shopping goers there are amazing shopping centers boutiques and the usual chain stores. I always pick up loads of goodies at Pacific Fair.

    The Gold Coast is popular for its theme parks-Sea World, Wamer Bros Movie World and Dream World. The seal and dolphin presentations at Sea World keep both children and adults on the edge of their seats as the sea creatures go through a series of complicated jumps, flips and rolls. It's great entertainment and an educational window to the underwater world for the kids. Our kids also enjoy meeting the characters at Movie World and watching how real movies are made.

    Night-time is equally fun, as we usually set off to find the best local restaurants and cafes. The mix of cultures and influences has given the Gold Coast a wide variety of choices, including modem Australian, Italian, Asian and seafood, although sometimes nothing beats fish and chips!

    A visit to the Gold Coast in the Sunshine State is worthwhile and fun.

    Culture shock is the psychological（心理的）shock of having to adapt to new environment and new cultures which may be completely different from your own. To understand culture shock helps to understand what culture is.

    Culture shock is caused by the feelings that result from losing all familiar signs and symbols of social intercourse（交往）. Those signs include the ways with which we are familiar in daily life: When to shake hands and what to say when we meet people? When and how to give tips? How to go shopping? When to accept and when to refuse invitations? These signs, which may be words, gestures, facial expressions, customs or normals are gained by all of us in the course of growing up and are as much a part of our culture as the language we speak.

    During the first few weeks when a person enters a strange culture, most people are attracted by the new. But this “cooks tour” type of mentality（心态）does not normally last if the foreign visitor remain abroad and has to seriously deal with real conditions of life. He may feel anxious and frustrated（受挫的） People react to the frustration in the same way. During the first period, they reject the environment which causes the discomfort. “The ways of the host country are bad because they make us feel bad,” they complain about the host country and its people. The following period is homesickness. The home environment suddenly becomes so important that all difficulties and problems are forgotten and only the good things back home are remembered.

    Experiencing culture shock can be very difficult. There is a risk of sickness or emotional problems. However, culture shock can be part of a positive learning experience. Be patient! It is a process of adaptation to new situations. If you do like this, you will be a much stronger person, and you will be a citizen of the world.

    Robots that can chat, find misplaced glasses, draw airplanes and play with your children are attracting thousands of visitors during an expo in Tokyo as Japan adapts to changes in society.

    Robots, such as the sound-sensitive Chapit, answer simple questions and even joke with people to help the solitary fight loneliness and stay alert (机警的) in old age. "Many old people in Japan live alone and have no one to talk to," said Kazuya Kitamura, a representative of the expo organizer. "Communication robots stay together with old people and don't mind listening to the same stories over and over again."

    While Chapit, a relatively simple robot, managed to attract a partner, many researchers, such as Kiyoshi Matsumoto, a professor at the University of Tokyo, struggle to attract sponsors for more expensive projects.

    Matsumoto's "Personal Mobility Robot", equipped with four cameras and a sensor to recognize the user's centre of gravity, is designed to help the elderly move around without pressing buttons as in traditional wheelchairs.

    The robot can also help find misplaced glasses by recognizing them with a sensor. "We have developed a robot that can assist many people, but because of the high cost, we still haven't found a sponsor," said Matsumoto, who added that the cost of the machine, if produced in large quantities, would be comparable to that of a small car. "In the current economic environment there are few companies willing to invest (投资) in such a costly project," he said.

    Other robots, such as the award-winning "DiGRO", can support busy parents who have little time to play with their children. The robot can use the Internet to find a simple image and then draw pictures, looking after children while parents work.

    Japan is one of the world's fastest-aging countries and the government predicts that by 2050 the population of people over 65 will reach 40 percent.
