这种桥有跑步机上的那种传送带,只要人一上去,一下子就过桥了。如果有人快要掉到水里,桥就会伸出一张比人还大的手,把人救上来。这样的桥还可以变成双层的,以便使一些有急事的人能先过桥,所以第二层叫做“急务层”。“急务层”有机器人看管着,这种机器人能在一秒钟内判断出想过急务层的人是否有急事,如果没有急事,那机器人会把这个人推回正常的第一层!
This kind of bridge has the conveyor belt on the treadmill. As soon as people go up, they will cross the bridge at once. If someone is about to fall into the water, the bridge will stretch out a bigger hand than people and rescue them. Such a bridge can also be double-layer, so that some people in urgent need can cross the bridge first, so the second layer is called "emergency layer". The "emergency level" is guarded by robots. This kind of robots can judge in a second whether the people who have thought about the emergency level have an emergency. If there is no emergency, the robots will push this person back to the normal first level!
这种未来的桥多方便啊!让我们好好学习,让这种桥早日发明出来。
How convenient this future bridge is! Let's study hard and make the bridge come out as soon as possible.
