Some students who are from all around the world are talking about the way they go to school on School Bus Bar at http://tieba.baidu.com/.
In our country, most of the students go to school by school bus. For me, I go to school by school bus every day. It takes me about 30 minutes to get to school, because my home is far from the school. The school bus is not only beautiful but wide and strong. It makes me feel safe when I am in school bus.

I think riding is one of the best ways to go to school because my school isn’t very far from my home. It takes me about 15 minutes. I like riding a bike and I think it’s good for my health. But nowadays, the number of the cars is becoming larger and larger and the crowded traffic will certainly bring about the risk of safety. So my parents hope that I can take the school bus to school.
Li Ping from Wenzhou
I went to school by bus one month ago, but now I walk to school with my parents or my classmates. It’s because the school bus accident. In the accident, lots of students died.
