Once upon a time，there was a boy named Tim. He lived in a small 1 with nice mountains（山） and rivers. It was great to play there， 2 Tim was always busy with his computer games and never noticed the beauty around him.
Tim's grandfather was worried and always 3 about how great the nature（自然） was with him. "What clean and beautiful lake it is!"，his grandfather often said. One day，but he was not very 4 .
As they walked in the village，Tim's grandfather pointed out many 5 things，such as colourful flowers with bright leaves，mother birds flying back homes with food to 6 their babies. They even climbed to the top of the hill so that they could see the sights 7 . His grandfather also told him some stories behind each place. Some of the stories were really funny and made Tim 8 all the time. Tim got to enjoy these beautiful things for the first time.
At the end of the trip，Tim's grandfather told Tim not to 9 the small things in life，like a sunny day or a friendly smile. From that day on，Tim learned to enjoy every moment and be thankful.
He thought that there was much more to life compared to 10 . Tim decided to spend more time outdoors and take short trips with his grandfather more often.
