1、When he woke up, he found himself tied to a tall tree。2, It is reported that our country has launched another spaceship。3, I was walking along the river when I saw a little girl dropped into the ice water。4, The car dashed into the crowd, several of whom were taken to the hospital immediately。5, Soon the soldiers took possession of the village。***根据卢rs3大师的建议，第三句改为：I was walking along the river when I saw a little girl falling into the ice water。谢谢大师！。
