Do you want to have a nice place to spend your weekend？Here are some places for you ,which are probably a mere walk away from your college.

King's Art Centre

    A day at the Centre could mean a visit to an exhibition of the work of one of the most interesting contemporary artists on show anywhere. This weekend sees the opening of an exhibition of four local artists.

    You could attend a class teaching you how to 'learn from the masters' or get more creative with paint—free of charge.

    The Centre also runs two life drawing classes for which there is a small fee.

The Botanic Garden

    The Garden has over 8,000 plant species；it holds the research and teaching collection of living plants for Cambridge University.

    The multi­branched Torch Aloe here is impressive. The African plant produces red flowers above blue­green leaves，and is not one to miss.

    Get to the display house to see Dionaea muscipula，a plant more commonly known as the Venus Flytrap that feeds on insects and other small animals.

    The Garden is also a place for wildlife ­enthusiasts. Look for grass snakes in the lake. A snake called 'Hissing Sid' is regularly seen lying in the heat of the warm sun.

Byron's Pool

    Many stories surround Lord Byron's time as a student of Cambridge University. Arriving in 1805，he wrote a letter complaining that it was a place of “mess and drunkenness”．However，it seems as though Byron did manage to pass the time pleasantly enough. I'm not just talking about the pet bear he kept in his rooms.He spent a great deal of time walking in the village.

    It is also said that on occasion Byron swam naked by moonlight in the lake，which is now known as Byron's Pool. A couple of miles past Grantchester in the south Cambridgeshire countryside，the pool is surrounded by beautiful circular paths around the fields. The cries of invisible birds make the trip a lovely experience and on the way home you can drop into the village for afternoon tea. If you don't trust me，then perhaps you'll take it from Virginia Woolf—over a century after Byron，she reportedly took a trip to swim in the same pool.

    How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.

    The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.

    The toothbrush will be able to teach you to brush right (don't forget the insides of the teeth!) and make sure you're brushing long enough. “It's kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.

    The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart but also fun,” Several says.

    Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.

    The company says the Kolibree will go on sale this summer, for $99 to $199, developing on features. The U.S. is the first target market.

    Serval says that one day, it'll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.

    When was the last time you relied on an old-fashioned map to figure out the route to an unfamiliar place? For many, the GPS has revolutionized navigation, making a paper map almost obsolete? So how has this piece of technology developed over its 26 years of existence? On February 14,1989,the first satellite in the US Global Positioning System was sent into space from Cape Canaveral, beginning the start of one of the wonders of the modern world.

    GPS stands for Global Positioning System, which is made of a network of around 30 satellites that move around the earth. The system uses a process called trilateration to find out one's position. By measuring the time it takes for the signal to reach one satellite, the GPS can determine your distance from the satellite, creating a sphere(范围) of possible locations. Measuring your distance from at least three satellites will narrow your location to the place where the three spheres cross one another, to the accuracy(精确) of about less than 1 meter!

    The GPS was first invented during the Cold War by the United States Department of Defense. In 1960, the first system, which was made of just five satellites, was put into place. It was initially created for strictly military(军事的) use; however, in 1983, as a result of faulty navigation technology, a Korean passenger plane mistakenly flew into USSR territory(苏联领土) and was shot down. In order to prevent such bad events, American President Ronald Reagan allowed civilian(民用的) use of the GPS.

    Over the next ten years, the system's accuracy improved as the network was increased to 24 satellites. And during the first Persian Gulf War, the new GPS was finally used by the military. Now scientists use the technology to track animals to better understand their movement and behavior. Parents who may be worried about their children can also use GPS technology to track them.

    What makes a gift special？Is it the price you see on the gift receipt？Or is it the look on the recipient's face when they receive it that determines the true value? What gift is worth the most?

    This Christmas I was debating what to give my father. My dad is a hard person to buy for because he never wants anything. I pulled out my phone to read a text message from my mom saying that we were leaving for Christmas shopping for him when I came across a message on my phone that I had locked. The message was from my father. My eyes fell on a photo of a flower taken in Wyoming, and underneath a poem by William Blake. The flower, a lone dandelion standing against the bright blue sky, inspired me. My dad had been reciting those words to me since I was a kid. That may even be the reason why I love writing. I decided that those words would be my gift to my father.

    I called back. I told my mom to go without me and that I already created my gift. I sent the photo of the cream-colored flower to my computer and typed the poem on top of it. As I was arranging the details another poem came to mind. The poem was written by Edgar Allan Poe； my dad recited it as much as he did the other. I typed that out as well and searched online for a background to the words of it. The poem was focused around dreaming, and after searching I found the perfect picture. The image was painted with blues and greens and purples, twisting together to create the theme and wonder of a dream. As I watched both poems passing through the printer, the white paper coloring with words that shaped my childhood. I felt that this was a gift that my father would truly appreciate.

    Christmas soon arrived. The minute I saw the look on my dad's face as he unwrapped those swirling black letters carefully placed in a cheap frame, I knew I had given the perfect gift.

    There are always stories in the life that can hardly be forgotten and will restore our hope for holidays every time we recollect.

    Johnny and I, along with our two young sons, Barry and Doyle, lived in a village in southern Alabama in 1979. We had bought the boys a bicycle for the New Year, and had hidden it in the garage ,where Johnny would assemble (组装)it on New Year⁵ s Eve after the kids fell asleep. But that day, Johnny had to go to Brookley Air Force Base in Mobile, an hour away, to repair a jet. I had my hands busy with baking, preparing for holiday dinner and caring for two energetic boys.

    Just as I was making the chocolate cake, a neighbor knocked on the door. It was Beatrice, who was the only person on our road with a telephone. The base had called to say that a heavy tool had come apart suddenly, hitting Johnny's arm and breaking the bone. My brother Otto took me to the base hospital while my mother stayed with the children.

    We got there to find Johnny with a cast (石膏)on his arm, anxious to get home regardless of the doctor's orders. It was New Year's Eve, Johnny argued, and he had the bike to assemble for his boys. The doctor said he'd consider dismissing him the next morning if Johnny could find someone to drive him home. On New Year's morning, Johnny called the base and was told everyone was off duty; there was no one to drive him home. Johnny kept making calls. At last, a big blue car with the Air Force sign rolled up.

    I was putting dinner on the table when hearing the car. We were thrilled to see Johnny assisted by a uniformed Air Force officer. With Otto's help, Johnny assembled the boy's gift, and they all had a good time that afternoon. Our hearts were full of gratitude to the people who had gone the extra mile to bring us together.

Imagine reading a story titled "Pursuing Success." That would be an inspiring story, wouldn't it? Maybe—but maybe not. It might well be the story of someone whose never-ending chase for more and more success leaves them unsatisfied and incapable of happiness.

Though it isn't a conventional medical addiction, for many people success has addictive properties. Obviously, success goes with praise. To a certain extent, praise stimulates the neurotransmitter dopamine (神经递质多巴胺), which contributes to all addictive behaviors.

The desire for success may be born to human nature, but specialness doesn't come cheap. Success is tough work, and it requires bearing the cost of losing. In the 1980s, the physician Robert Goldman famously found that more than half of ambitious athletes would be willing to take a drug that would kill them in five years in exchange for winning every competition they entered.

Unfortunately, success is endless. The goal can't be satisfied; most people never feel "successful" enough. The high only lasts a day or two, and then it's on to the next goal. Psychologists call this the hedonic treadmill (快乐跑步机现象), in which satisfaction wears off almost immediately and we must run on to the next reward to avoid the feeling of falling behind.

People should get off the treadmill. But quitting isn't easy for addicts. For people hooked on substances, withdrawal can be a painful experience, both physically and psychologically, research finds that depression and anxiety are common among outstanding athletes after their careers end. Olympic athletes, in particular, suffer from the" post-Olympic blues."

Just like wine, success in and of itself is not a bad thing. Both can bring fun and sweetness to life. But both become bossy when they are a substitute for — instead of a complement (补充物)to — the relationships and love that should be at the center of our lives.
