One of my first memories as a child in the 1950s was a discussion I had with my brother in our tiny bedroom in the family house in Bethlehem, Pennsylvania.

    We had heard in school about a planet called Pluto. It was the farthest, coldest, and darkest thing a child could imagine. We guessed how long it would take to die if we stood on the surface of such a frozen place wearing only the clothes we had on. We tried to figure out how much colder Pluto was than Antarctica, or than the coldest day we had ever experienced in Pennsylvania.

    Pluto, which famously was downgraded from a “major planet” to a “dwarf planet”（矮星） in 2006, captured our imagination because it was a mystery that could complete our picture of what it was like at the most remote corners of our solar system.

    Pluto's underdog discovery story is part of what makes it so attractive. Clyde Tombaugh was a Kansas farm boy who built telescopes out of spare auto parts, old farm equipment and self-ground lenses. As an assistant at Lowell Observatory in Flagstaff, Arizona, Tombaugh's task was to search millions of stars for a moving point of light, a planet that the observatory's founder thought existed beyond the orbit of Neptune. On February 18，1930，Tombaugh found it. Pluto was the first planet discovered by an American, and represented a moment of light in the midst of the Great Depression's dark encroachment (入侵).

    Pluto is much more than something that is not a planet. It's a reminder that there are many worlds out there beyond our own and that the sky isn't the limit at all. We don't know what kinds of fantastic variations on a theme nature is capable of making until we get there to look.

    Going green seems to be fad(时尚)for a lot of people these days.Whether that is good or bad，we can't really say, but for the two of us，going green is not a fad but a lifestyle．

    On April22nd，2011，We decided to go green every single day for an entire year．This meant doing 365 different green things，and it also meant challenging ourselves to go green beyond easy things．Rather than recycle and reduce our energy, we had to think of 365 different green  things to do and this was no easy task．

    With the idea of going green every single day for a year .Our Green Year started．My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all the green things that could be done to help the environment．We wanted to push the message that every little bit helps．

    Over the course of our Green Year, we completely changed our lifestyle．We now shop at organic(有机的) stores．We consume less meat, choosing green food．We have greatly reduced our buying we don't need．We have away half of what we owned through websites．Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made flesh bread .In our home office anyone caught doing something ungreen might be punished．

    Our minds have been changed by Our Green Year．We are grateful for the chance to have been able to go green and educate others .We believe that we do have the power to change things and help our planet．

    I'm learning to drive in Switzerland. I think it will be a good idea to learn now because I have plenty of free time and am earning a little money to pay for lessons. I never learnt when I lived in the UK, so luckily driving on the "wrong" side isn't a problem.

    However, there are a lot of rules to remember. When you see a road to your right and there are no white lines on the ground, the cars to your right have the right to go before your car and you have to stop for them. In practice, lots of people forget this and cars either wait for each other while both drivers try to remember what to do, or beep (鸣喇叭) at each other if both try to go at the same time!

    When you drive round a roundabout, you should check all your mirrors. To remember how to do this, I often count them aloud—one, two, three—then a second glance at your blind spot when you're in the roundabout. One friend came driving with me and after about an hour asked why on earth I was counting. He had passed his test so long ago, he couldn't remember ever having to check three mirrors!

    Driving still seems scary to me so I drive quite slowly. I also don't know the countryside roads very well and don't know what's coming up round the comer or over the next hill. I drive slowly so I feel safe, but my driving instructor tells me to speed up or cars will bump into me from behind or try to overtake somewhere dangerous. So driving slowly is just as dangerous as driving fast!

    I'm not a very practical person so learning to drive has been a challenge. I don't have a lot of confidence and find it quite demotivating to do something that doesn't come naturally to me. To make driving more fun and interesting, I learn in Swiss German, so my instructor gives me instructions in Swiss. This way I've tricked myself into enjoying driving and hopefully will pass the test!
