I go to school by bus every day.There are always many people waiting at the bus stop, because there is only one bus every 20 minute.It¡¯s very difficult for students to get on the bus.The bus is full of people and some of them have to stand.It¡¯s dangerous sometimes. And the air on the bus is not so fresh.It¡¯s bad for our health.I hope there will be more buses.
