Welcome to your future life!

    You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people of your age could live to be 150, so at 40, you're not old at all. And your parents just had an anti-aging (抗衰老的) treatment. Now, all three of you look the same age!

    You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles(粒子) much smaller than the cells in your body. The particles can be programmed to change clothes' color or pattern.

    You walk into the kitchen. You pick up the milk, but a voice says, “You shouldn't drink that!” Your fridge has read the chip (芯片) that contains information about the milk, and it knows the milk is old. In 2035, every article of food in the grocery store has such a chip.

    It's time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way. You can call a friend using your jacket sleeve. Such “smart technology” is all around you.

    So will all these things come true? “For new technology to succeed,” says scientist Andrew Zolli, “it has to be so much better that it replaces what we have already.” The Internet is one example. What will be the next?

    One of the traditions which is now a necessary part of Christmas is that of Father Christmas, or Santa Claus. According to the modern legend, he is a magical figure who visits all the children of the world during the night before Christmas Day, leaving presents, which they find the next morning. He flies through the night sky in a sledge pulled by reindeer, and enters houses by climbing down chimneys. This strange legend is based on the life of a man called Nicholas, but in fact we know very little about him. Historians think he was a Christian bishop（主教）in Turkey in about 285-350 A.D. One of the stories about him is that he helped three poor girls. No one would marry them because they were so poor.

    To provide them with money for their weddings, Nicholas secretly dropped some gold coins down the chimney of their house. After Nicholas died, he was made a saint（圣人）by the church. (The name Santa Claus thus comes from St Nicholas.) His feast day was celebrated in December, and parents started giving their children secret presents from St Nicholas. Over the years, this custom became part of our Christmas traditions.

    Recently, a psychologist has claimed that Father Christmas is “the perfect fantasy” for children. According to Professor Anthony Clare, children love the character of Father Christmas because he is like an ideal father: he loves children and gives them presents, but he never criticizes them, is never angry and children do not even need to thank him for presents. Other writers, however, point out that Father Christmas can be a frightening character to some children. Jane Bidder says that some children are terrified of this fat, bearded old man. It can certainly confuse many children. As presents, we warn our children to be careful of strangers and never to let them into the house, and yet we tell children that a strange man will come into their bedroom at night! Some children can become very worried about this idea and fear that he is a kind of burglar.

    Most children, however, understand from their parents and from the media that Father Christmas is basically a benign character, and look forward to his annual visit with joy and excitement.

    Atlantic puffins（角嘴海雀）are specially used to living on the open sea. Their feathers allow them to stay warm as they float at the ocean's surface or swim underwater. Diving as deep as 60m, they swim by flapping their wings as if flying through the water. There, they hunt herring, capelin, and sand eels.

    Atlantic puffins are also excellent fliers. Flapping their wings at up to 400 beats per minute, puffins can reach speeds of 88km/h.

    April to mid-August is the breeding season for puffins. When a puffin is around three to five years old, it will choose a partner at sea to mate with for life. It is thought that the birds' colourful bills and feet, which fade in the winter and brighten in the spring, help puffins find their potential（可能的）mates.

    Puffins create shelter（庇护所）, about 90cm, in rocky cliffs either in the soil or between rocks. Often, couples will return to the same shelter year after year. At the back of the shelter, they build a nest lined with grasses, seaweed, and feathers. After the female lays a single egg, both parents take turns incubating（孵化）the egg for about 40 days.

    Once the chick hatches, the mother and father will take turns bringing it fish to eat several times a day. Atlantic puffins have the ability to carry several fish in their beaks at one time. The ridges（脊）at the top of their bill hold the fish in place, which allows puffins to keep their mouth open to catch more fish without losing any. In general, they can hold around ten fish in their beak at one time.

    In the wild, puffins can live around 20 years. Their main predator is the great black-backed gull, which can capture a puffin mid-flight or attack a puffin on the ground. Gulls are also a threat because they steal puffins' fish (sometimes right from their mouths), and they pull puffin chicks or eggs from their nests.

    Running seems easy enough: Just grab a pair of sneakers and put one foot in front of the other, right? Well, anyone who struggled to get through a mile knows it's not quite that simple. We've asked experienced runners to tell us something wrong they did when they started running. The following are some of their answers.

    I got excited and signed up for a half-marathon with a few more experienced runner friends, but I wasn't adequately prepared and didn't train efficiently. I ended up with blisters(水泡) on my feet. I couldn't wear shoes for two days!

    I have always been athletic and I have never been badly injured, but one day I felt a slight pain in my knee. I ignored it for a month until I realized I was having a hard time putting weight on my right leg. I finally went to a doctor. It took four months of weekly physical therapy(治疗) to heal. I shouldn't have done that.

    My biggest mistake was treating running like soccer practice: If I wasn't exhausted by the end of practice, I felt as though I didn't work hard enough. I run all of my runs at 80 percent effort, or the equivalent of what I now call tempo runs (节奏跑). I wasn't warming up to the pace or cooling down effectively.

    I decided to go out for a run during the hottest part of the day. At the time, I told myself that it would be refreshing to sweat a little, but I didn't bring adequate water. I returned feeling completely rundown, dehydrated (脱水的), and exhausted. If you must go out on a run during unfavorable weather, wear proper suits and bring enough water to keep you feeling strong.

    Everybody seeks happiness in the world. We will be really happy when we get a new car or a big house or get married... The thing is, if we are continually searching for happiness in the outside world, we will be very disappointed. It seems as if we are forever chasing it and it is always just one step away.

    Happiness is a short state of mind, just like the state of sadness or joy or anger. It would not be possible for us to be in a happy state 24 hours a day. If you think that sounds laughable, think about being at a funeral when everyone is mourning. Would it feel right to go about with a huge smile on your face?

    What we go through in our lives helps us grow and understand the value of happiness. We need to be able to respond in all manner of ways according to what we are dealing with at any given time. All emotions and states are part of the life.

    Happiness can be found in reaching out and being in relationship with people. Though time or money may be lost in helping others, these will become our happy memories. Happiness is a dance with whatever in front of you. It is a deep connection to everything around you. It does not come from expecting others to bring you joy but from how you can create joy for others.

    If you want to experience happiness more often, see what you can do to put a smile on someone else's face each day and notice how much happier you feel when you have achieved that. Happiness is not to be found in material possessions. It is freely available to everyone at any time. All that is required to experience happiness is that you place your focus on moments in your life that make you smile.

    If you have never been on a cruise (乘船游览), it can seem like its own world—with its own rules and secret language. So here we are going to lay out the very basics of going on a cruise.

    Do I need a passport to go on a cruise?

    You may need a passport, but you should take one anyway. Besides the fact that you are going to need an ID card to board the ship in the first place, a lot of ports require one.

    How much luggage can I take on board?

    For the most part, cruise ships aren't like planes—there isn't a strictly regulated amount of luggage you can take with you, and you are not going to be charged for bringing too much. Keep in mind that cabin storage space can be tight. Everything, including your empty luggage, is going to have to fit inside and you don't want to be tripping over it for your whole vacation.

    Things like guns and knives are banned, but regulations vary from ship to ship about things like irons (generally a no) and hair dryers (generally a yes). Some ships allow you to bring a bottle of wine, but nearly all ban bringing your own hard alcohol.

    What's the process for boarding a cruise ship?

    Boarding a cruise ship is like boarding a plane—there are regulations or when to arrive, how to check-in, and what security you have to go through. Most cruise lines have transportation available from the airport; otherwise they normally own a paid parking lot where you can leave your car.
