（A）
Overhead bridges are found in many parts of. Beijing, especially in places where   traffic is very heavy and crossing the road is dangerous.
The purpose of these bridges is to enable pedestrians to cross roads safely. Over-   head bridges are used in very much the same way as zebra crossings. They are more ef-                                                       ficient although less convenient because people have to climb up a long flight of steps.   This is inconvenient especially to older people. When pedestrians use an overhead   bridge, they do not hold up traffic. However, when they cross a busy road using a ze-   bra 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.
The government of Beijing has spent a large amount of money in building these   bridges. For their own safety, pedestrians should be encouraged to use them instead of   risking their lives by dashing across the road. Old people, however, may find it a little   difficult to climb up and down the steps, but it is still much safer than walking across   the road with all the danger of moving traffic.
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.
