大伟与小海放学回家的路上被歹徒抓住,歹徒把大伟与小海关进了一间空屋子里,虽然空屋子里的窗户是开着的,但大伟和小海的手都被歹徒用绳子绑了,为了防止他俩逃跑,歹徒又把两条绳子交叉了一下,这样,即便窗户开着,两人也不能够一起逃跑出去,除非把两人手上的绳子分开,可是空屋子 Dawei and Xiaohai were captured by culprits on their way home from school. The culprits brought Dawei and Xiao Customs into an empty room. Although the windows in the empty room were open, Dawei and Xiao Hai’s hands were criminals. With the ropes tied, in order to prevent them from escaping, the criminals again crossed the two ropes so that even if the windows were open, the two could not escape together unless they separated the ropes from their hands.
