Wang Wei: It was a sunny but a little cold morning. I with many people went to hills outside the city.We dug the holes, planted the small trees and watered them well.I hope we can make our environment greener and more beautiful.
Jiang Jian, One Sunday, I went to visit the kids who were not well in hospital. I stayed with them all the morning,playing games,taking walks,or even helping them with homework.While I was with them,time went quickly.
Hu Peng , It was a meaningful and educational trip for me.We family went to a village in the mountains.There we stayed with five children whose parents couldn’t come back home for the festival with them. During the three days,we did many interesting and helpful things.  .
Ma Lili,  One of the most important and meaningful things for me in the winter holiday is to join Cleaning Our City.We cleaned the street,picked up the rubbish and called on more people to help out with our city.
Shao Bing: During the last week, I with my classmates went to see the old people. We bought some fruit ,flowers and something else. We cleaned the house,talked with the old people. Some of us sang and danced ,some read newspapers to them. I am sure it was the most enjoyable time for the old people,and for us,too.
