假设没有了挖掘机加长臂这类的机械是否能建成一条好的铁路呢？
Suppose there is no such machinery as excavator extension arm, can a good railway be built?
认为或许可以，但是过程会比较困难。了解历史的人都知道，我国的挖掘机是在我国成立之后才出现的，而在那个年代之前的清政府时期，就没有依靠挖掘机加长臂这类的机械，却在这片广袤的土地上建成了十几条铁路，这十几条铁路中以京张铁路较被人知道，但是保留今依旧在使用的只有一条，那就是宝成铁路，它位于陕西略阳县境内，你可千万别小看这条铁路，它现在可是我国一级货运和客运的干线，坐上这列车你可以大肆的领略到祖国北疆的异域风景。可真没想到，腐败的清政府虽然在政治上有着严重的腐败现象，但是在改善民生上确实有不少造诣，但是当时并没有挖掘机，更别说加长臂，但是依靠人力却造就了一条造福今的铁路，想必当时建造起来也不简单。
Maybe, but the process will be difficult. Those who know the history know that the excavator in our country came into being after the founding of our country. Before that time, during the Qing government, there was no machinery such as excavator extension, but a dozen railways were built on the vast land of China. Among the dozen railways, the Beijing Zhangjiakou Railway is better known, but the only one that remains in use today is the Baoji Chengdu Railway, It is located in Lueyang County, Shaanxi Province. Don't underestimate this railway. It is now a first-class freight and passenger trunk line in China. You can enjoy the exotic scenery of the northern border of the motherland on this train. It was unexpected that although the corrupt Qing government had serious corruption in politics, it did have a lot of accomplishments in improving people's livelihood. However, there was no excavator at that time, let alone an extra arm. However, relying on manpower, it created a railway that has benefited the present. It must not be easy to build it at that time.
不仅在铁路修建方面，我们不能辜负挖掘机加长臂，在其他方面也是一样的。现在虽然我们有了加长臂，架桥和铺设铁轨的速度成倍上升了，但是我们也不能停止不前，研究架桥技术，研究挖掘机加长臂的技术依然是我们不屑的努力方向，只有这些都更了，我们的生活才会更美好。
Not only in railway construction, but also in other aspects. Now, although we have lengthened arms, the speed of bridge erection and rail laying has doubled, we can't stop. Studying bridge erection technology and excavator arm extension technology are still our disdainful efforts. Only when these are more advanced, our life will be better.
