任务型阅读，根据表格内容，完成所给任务（每空一词） There is a very popular organization with young people in our community. I joined it two years ago. And I have taken part in many interesting activities. What we have done can not only help others but also make ourselves happy. Last Sunday, we went to an old people’s home. After helping them do some housework, we sang, danced and played games with them. The old people were excited at our visit. They told us interesting stories about themselves. We all had a good time. After this visit, my friend and I decided to do more things to help them. Now more than 30 volunteers have joined our club. Everyone thinks the experience is wonderful.
