在一些大江大河上,横跨江面的大桥桥面很长,人们从桥上走过要用很长的时间,遇上刮风下雨就更难受了。我想,如果大桥两边的人行道做成像传送带一样的电动人行道,人们只要站在“传送带”上,就被安全地送过河去,还可以同时欣赏两边的风景,岂不两全其美。筌电动大桥$广西藤县太平镇 On some big rivers, the bridge deck across the river is very long. It takes a long time for people to walk over the bridge. It is even more troublesome when it comes to windy weather. I think if the sidewalks on both sides of the bridge are made like conveyor-like electric walkways, people will be safely transported across the river as they stand on the “conveyor belt” and enjoy the best of both worlds at the same time.筌 Electric Bridge $ Guangxi Tengxian Taiping Town
