It might have been a really bad stressful day, feeling trapped inside by the cold and snow which surrounded us. My husband got dressed and  36  that he was going outside to build a giant snowman.
At first he stood alone, 37  massive amounts of snow. Soon after a neighbor joined in. Then we reluctantly put on our snow gear(装备) and  38  outside. It wasn’t long  39  we were smiling and enjoying the  40  of snow that Mother Nature had provided. Others came to our yard one by one to give a  41  in the making of our giant snowman.
In the end we all stood back and  42  at what we had created. He was eleven feet high, twenty-five feet around at the base and  43  with many household items supplied by various  44  .People drove by and smiled. Some even stopped just to enjoy his  45 .
With the passing of time, the spring made its  46  back into our yard and the snowman changed form  47  .In a final effort to save what we created for just a little bit  48  ,somebody stopped by and changed the snowman’s  49  to look like a rabbit.
As I prepared for the start of another week, I decided to  50  my email before going to bed. I found a  51  message that contained the subject line: 52  the snowman.
The email said:… your neighbor looks on in disbelief! Now you people are relishing(享受) the sounds and smells, along with  53  of spring. But I am sure people will never forget the  54  energy displayed in Mr Snow-man. You and your family keep it up, as this is what the world needs now. More power to you and your loved ones, keep  55  with the world around!
