未来的桥

未来的桥是什么模样？有多长？有多宽？如果我是桥梁设计师的话，那……

What is the future bridge like? How long is it? How wide is it? If I'm a bridge designer, then

未来的桥是用金钢银铁制成的，一亿头非洲大象踩上去都不会塌，不会坏。这种桥没有桥墩，只有两根柱子支撑着。每根柱子下面都会有几个十分耐用的轮子。这种轮子可以根据场地的变化而变化。比如果要是遇到了下雨天，轮子就变成防滑的轮子……有了这种轮子，桥就可以随时移动地方。

The bridge of the future is made of steel, silver and iron. A hundred million African elephants will not collapse or break when they step on it. The bridge has no piers, only two pillars. There will be several very durable wheels under each column. The wheels can vary according to the site. If it rains, the wheel will become a non slip wheel With this kind of wheel, the bridge can move at any time.

这种桥还很美观。桥身两侧有精美的木雕。有的刻着深山老林；有的刻着龙和凤；有的刻着双龙戏珠，还插着各种颜色的彩旗，迎风飘扬。

This kind of bridge is beautiful. There are exquisite wood carvings on both sides of the bridge. Some are carved with mountains and forests; some are carved with dragons and phoenixes; some are carved with two dragons playing with beads, and are decorated with colorful flags of various colors, flying in the wind.

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.
