It is time to go to school. He puts his books into his backpack. He puts his arms through the straps. He puts his backpack on his back. He walks outside. He goes to the bus stop. He stands at the bus stop. He waits for the bus. He sees the bus.
该上学了。他把书放进背包里。他把胳膊穿过带子。他把背包放在背上。他走到外面。他去公共汽车站。他站在公共汽车站。他在等公共汽车。他看见公共汽车了。
