以下是俄国化学家罗蒙诺索夫曾开展的实验：

①先用天平称取质量为m₁的金属锡粉．

②将这些锡粉放在密闭容器里进行完全燃烧，生成了白色固体物质，称量容器的总质量为m₂．

③打开容器，听到了空气进入容器发出的“丝丝的声响”，称量所得白色物质的质量为m₃．

④把白色物质放回原容器里（容器中空气的组成恢复到初始状态），重新称量容器的总质量为m₄

  20世纪初，著名的物理学家爱因斯坦建立了____，使人们对时空观的认识产生了根本性的变革.

    The ant(蚂蚁) works every day but the monkey plays in the tree every day in summer. One day the ant is carrying some candy to her home. Her home is next to a big tree. The monkey is playing games in the tree. He says to the ant, “Why are you working every day? It is warm today. Don't work. Come and play games with me.” But the ant says, “Winter will come and it will be very cold. I want to store lots of food. I will sleep all day in winter.”
    Winter will not come soon. You can work in autumn,” says the monkey.
    Summer and autumn are over. There is snow(雪) everywhere. The monkey can't find any food. Do you know what will happen?
