A possible version:
Everyone likes to spend their birthday, but the ways to celebrate it vary from person to person. Here are the four ways my classmates usually do.
About half of us would like to hold a birthday party with friends and classmates, so that they can chat, sing and do whatever they like. In that case, they may promote their feelings with each other. Some, about 20%, prefer to travel, for they hope to get close to nature and relax themselves.
However, about one third of my classmates wish to receive some special gifts, such as a mobile phone, an iPad, from their parents. Lastly, one classmate in ten wants to plant a tree on the very day, which I think is really meaningful.
