让大海快速结冰成都实验小学成都花园分校许植、李泰浩:在未来世界,我们会发明一套装置,它既可以预报海啸的发生,又可以射出钻土弹摧毁地震。在海啸来临之前,它会告之人们,然后发射出钻土弹,射向地震中心,并根据海啸的强弱钻入海底一定的深度后爆炸。这样既能防止海啸的发生,又能减少对海洋生物的破坏。我们还要发明一种快速冰冻器。每当有海啸袭来时,它可以立刻将海水结成冰。而且这些冰经过处理,提取出冰中的有害物质,还可以运送到沙漠中,给沙漠供水。这样海边的家家户户可以平平安安,沙漠也变成了绿洲…… Let the sea quickly icy Chengdu Experimental Primary School Chengdu Branch Xu Zhi, Li Taihao: In the future world, we will invent a device that not only predicts the occurrence of a tsunami, but also shoots earth and rockets to destroy the earthquake. Before the tsunami comes in, it will tell the people and then launch earth and mortar shells that will strike the center of the earthquake and explode to the depths of the sea as the tsunami blows. This will not only prevent the tsunami, but also reduce the damage to marine life. We also want to invent a quick-freeze. Whenever there is a tsunami, it can immediately icing seawater to ice. And these ice are treated to extract the harmful substances in the ice, but also can be transported to the desert, water supply to the desert. In this way, every household in the sea can be at peace and the desert has become an oasis.
