War, money and power are a few things that countries and people are concerned about．1  I agree that those things are important, I believe that everyone should start to  2  more on a growing problem—global warming．

       Global warming will not only  3  our country and our generation, but also the entire  4 and future generations．It is  5  because the weather has been a lot wanner over the past few years which  6  the melting（融化）of the ice in the Antarctic．This will soon cause water levels to  7  and flood parts of the world．

       Many people ignore this problem because they feel _8_  they can't do anything about it and have more  9  things to worry about．If we all  10  so, then our ozone layer （臭氧层） will be  11  and the planet will no longer be able to make life continue to exist．We should do our best to limit the use of our planet's  12  resources （资源） and keep our air clean．  13  , future generations will suffer from our  14  ．

       Some might feel that they can't stop global warming from  15  ．But if every single person does his or her part in keeping the air clean, then it will become a  16  effort．Sure, there are some things that cause pollution and that we won't be able to  17  change．This may include cars burning oil, but we can  18  adjust some of these things．People can start carpooling, taking the bus, riding their bikes, or  19   just walking．

       If everyone takes  20  now, I believe we can start seeing remarkable results within a few

years．

    One afternoon，many years ago，I went to pick up my mother from work．I got there a little early so I   16   the car by the roadside，across the street from where she worked and waited for her．

     As I looked out of the car window to my right, there was a small park where I saw a little boy  17  one and a half to two years old,   18  freely on the grass as his mother watched him from a short distance．The boy had a big smile on his face  19  he had just been set free from prison．The boy would then fall to the grass，get up，and without  20  ．run as fast as he could，

again，  21   with smile on his face，as if nothing had happened．

     22  ，with kids(especially at all early age)，when they fall down，they don't perceive(认识到)their falling down as a(n)   23  ，but instead, they treat it as a learning   24   ，as just another outcome(后果)．They will try and try again until they   25  ．The answer must be that they have not   26  “falling down”with the word“failure”yet．Thus they don’t  know how to feel the state which accompanies failure．What's more，they probably think that it is perfectly okay to fall down，and that ifs not   27  to do so．In other words，they give themselves   28  to make mistakes subconsciously(潜意识地)．Thus they remain   29  ．

    While I was touched by the boy’s  persistence(坚持不懈)，I was   30   touched by the manner in which he ran．With each  31  ，he looked so confident and so natural．No  32  of fear, of nervousness，or of being discouraged…as if he didn’t    33  the world around him．His only  34  was to run freely and to do it as effectively as he could．I learned a lot from that observation and experience，and had successfully brought that   35   with me in my many pursuits(追求)in life．
