▌作品介绍：龙子湖是我们蚌埠市的风景名胜，美丽极了。但是在去年的三四月份，一种叫做菹草的水生植物长满了湖面，既影响了景色又给水体带来了巨大的危害。我发明一种机器鱼，它们可以迅速的把有害的水生植物吃掉，还能在体内把植物转化成营养物质重新投放到水里。另外龙子湖里还发现有人放养鳄龟，这种来自美洲的乌龟性格凶猛，对龙子湖里的生物危害很大。我发明的机器鲨鱼可以把鳄龟这样的对环境产生危害的外来物种抓住，保持生态平衡。
此文自动翻译Introduction:Longzi Lake is the scenic spot of Bengbu City, which is extremely beautiful. But in March and April last year, an aquatic plant called Potamogeton crispus grew all over the lake, which not only affected the scenery but also brought great harm to the water body. I have invented a kind of robot fish, which can quickly eat harmful aquatic plants, and transform plants into nutrients in the body and put them back into the water. In addition, crocodile tortoises are also found in Longzi Lake. This kind of tortoise from America has a fierce character and is very harmful to the creatures in Longzi Lake. The robot shark I invented can catch the crocodile turtle, which is harmful to the environment, and keep the ecological balance.
