假如我是科学家450字英语作文带翻译 假如我是个科学家，我要发明许许多多为人们造福的机械。 If I were a scientist, I would invent many machines for the benefit of people. 我要发明一种有反重力板在螺旋桨上的”竹蜻蜓”。它是有一种螺旋桨在转，有很小的电脑在运行，可以依照你的指示来进行左右运动。操作很简单，先把”竹蜻蜓”戴在头上，因为上面有吸入机，会吸住你，而你也不会觉得痛，所以不用担心。带上去后按下开关，你就会飞起来了，这样就不会有污染了。 I want to invent a kind of “bamboo dragonfly” with anti gravity plate on the propeller. It has a propeller running and a small computer running. It can move left and right according to your instructions. The operation is very simple. First, put the “bamboo dragonfly” on your head, because there is a suction machine on it, it will suck you, and you will not feel pain, so don＇t worry. Take it up and press the switch, you will fly, so there will be no pollution. 我还要发明一种叫”随意门”的机器。只要握着门把，就可以去到世界各个角落，和宇宙十光年以内的地方，这样就不会发生事故了。但如果同时使用的人太多，空间扭曲装置会坏掉，所以有些人只能用”竹蜻蜓”了。但是这两样道具都有缺点，”竹蜻蜓”的缺点是电池只能维持4小时，用手根本换不了电池。随意门的缺点是坏人如果用了四维阻止，”随意门”就会完全坏掉。 I also want to invent a machine called “random door”. As long as you hold the doorknob, you can go to all corners of the world and places within ten light-years of the universe, so there will be no accidents. But if too many people use it at the same time, the space warping device will break down, so some people can only use “bamboo dragonflies”. However, both of these props have disadvantages. The disadvantage of “bamboo dragonfly” is that the battery can only last for 4 hours and can＇t be replaced by hand. The disadvantage of random door is that if the villain uses four-dimensional stop, the “random door” will be completely broken. 我还要发明一个叫四维空间口袋的道具。它无论装了多少东西在里面都行，如果想拿东西，你想着它的名字和形状就可以拿到了，而且很轻便。不过它的缺点是一爆发就完了。 I also want to invent a prop called a four-dimensional space pocket. No matter how many things it contains in it, if you want to take something, you can get it by thinking of its name and shape, and it＇s very light. But its disadvantage is that it＇s over as soon as it erupts. 假如我是个科学家是件多么美好的事情啊！这不是比发明一些武器更好吗？”竹蜻蜓”、”随意门”和”四维空间口袋”的缺点也要靠我们大家区改进！ What a wonderful thing it would be if I were a scientist! Isn＇t it better than inventing some weapons? The shortcomings of “bamboo dragonfly”, “random door” and “four-dimensional space pocket” also depend on our improvement! 本文来源：https://www.wddqw.com/doc/8000474eb5360b4c2e3f5727a5e9856a57122616.html
