“车到山前必有路”。其实车到哪里都必须有路。不能开动的车从实质上说不能算是车,而要开动就必须上路。因此,无论从功能还是结构上说,路都是概念和现实的车的必然组成部分。鲁迅曾经说过“地上本没有路,走的人多了,也便成了路”。这话长期被当作至理名言,但是用在车道上则有些不对了。车道可不是人行小路,可以“走”出来的。它要求一定的宽度、长度、坡度、弯度,不可能单凭人走路自 “There must be a car to the mountain road ”. In fact, where the car must have a way. Can not start the car in essence can not be regarded as a car, but to start it must be on the road. Therefore, both in terms of function and structure, the road is an integral part of the concept and the reality of the car. Lu Xun once said “there is no way on the ground, more people go, it has become a road ”. This statement has long been used as a famous saying, but used in the driveway is some wrong. Lane is not a pedestrian path, you can “go ” out. It requires a certain width, length, slope, camber, impossible to walk alone
