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 .

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.

More power to you and your loved ones, keep 55  with the world around!
