Overhead bridges are found in many parts of Beijing, especially in places where traffic is very heavy and crossing the road is dangerous.

　　高架桥在北京的许多地方，尤其是在地方交通非常拥挤，过马路是很危险的。

　　The purpose of these bridges is to enable pedestrians (行人) to cross roads safely. Overhead bridges are used to very much the same way as zebra crossings. They are more efficient (效率高的) although less convenient because people have to climb up a long flight of steps. This is inconvenient especially to older people. When pedestrains use an overhead bridge, they do not hold up traffic. However, when they cross a busy road using a zebra crossing, traffic is held up. This is why the government has built many overhead bridges to help pedestrians and to keep traffic moving at the same time.

　　这些桥梁的目的是为了使行人过马路安全(行人)。高架桥用来非常相同的方式在斑马线。他们更有效(效率高的)虽然不太方便，因为人们爬上了长长的台阶。这是老年人特别不方便。当行人使用高架桥，他们不阻碍交通。然而，当他们穿过一条繁忙的道路使用斑马线，交通受阻。这就是为什么政府建造了许多高架桥让行人和车辆保持在同一时间移动。

　　The government of Beijing has spent a large amount of money on building these bridges. For their own safety, pedestrians should be encouraged to use them instead of risking (冒…危险) their lives by dashing across the road. Old people , however , may find it a little difficult climbing up and down the steps, but it is still much safer than walking across the road with all the danger of moving traffic.

　　北京政府已对这些桥梁建设投入了大量资金。为了自己的安全，行人应被鼓励使用他们，而不是冒险(冒……危险)冲过马路的生活。人老了，然而，可能觉得有点困难，爬上爬下台阶，但仍比穿越马路的所有安全行车的危险多了。

　　Overhead bridges serve a very useful purpose. Pedestrians, both old and young, should make it a habit to use them. This will prevent unnecessary accidents and loss of life.

　　高架桥非常有用。行人，既古老又年轻，应该使用他们的习惯。这将防止不必要的事故和生命损失。
