参考范文
Previously，I lived in the countryside where the sun always rose.Every morning，I got up early to see the sunrise.As the sun came out，trees，flowers，birds and other animals woke up from their long sleep and smiled gently towards the sun.“What a beautiful view！”I whispered.
But as I moved to the city，I could hardly see such a beautiful view now.Nowadays，with the development of society，the living step is so fast that we are always so busy and we don’t even have the time to take a breath.While in our free time，we can do nothing but play computer games.What a dull life it is!
I eagerly want to return to our nature.
