There are a lot of overhead bridges in Singapore, in the places where traffic is very heavy and crossing the road is not safe. These bridges can make people cross roads safely. Overhead bridges are used in very much the same way as zebra crossings.

The overhead bridges are more useful, though people have to climb up a lot of steps. When people use an overhead bridge, they do not hold up traffic. But 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 and keep traffic moving at the same time.

The government of Singapore has spent a lot of money building these bridges. Some overhead bridges even have traffic lights on them. For their own safety, people should use them. Old people 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 moving traffic.

Overhead bridges are very useful. People, old and young, should always use them. This will help stop accidents from happening.

When you are in England, you must be very careful in the street because the traffic drives on the left. Before you cross the street, you must look to the right first and then the left.

In the morning and in the evening when people go to or come from work, the streets are very busy. Traffic is the most dangerous then.

When you go by bus in England, you have to be careful, too.Always remember the traffic moves on the left, so you must be careful. Have a look first, or you will go the wrong way.

In many English cities there are big buses with two floors. They are called double-decker buses.（双层车） You can sit on the second floor. From there, you can see the city very well. It’s very interesting.

Car Times Have Come to China

In late April, 33-year-old Li Yang climbed into her new car, a home-made Suzuki Alto and headed west. She “just kept going to see how far I could get by myself”. Six days and 2,575 kilometers later, she arrived in Lhasa, the Tibetan capital. Happy and tired, she wrote an article and put it on the Internet after she had a good sleep, talking about her travel experience to Lhasa with photos.

As people become richer and richer, new car prices are falling down quickly, and the government builds new ways, many Chinese people think it is enjoyable to have their own cars instead of bicycles. The large number of cars has started a new cultural revolution (革命), changing the life and society just like what happened in America 50 years ago.

In Shanghai, more and more cars have appeared on the roads since 2002. The roads here are getting busier and busier. At rush hour, a taxi ride from one side of Huangpu River to the other can take more than an hour. Although the government has done a lot to make the traffic condition better and prevent more traffic accidents from happening, the number of cars on the roads is multiplying (成倍的增加).

Private cars have brought about a new class of society, who drive to their offices from large, modern homes in the suburbs (郊区). “I enjoy the drive,” says a big company manager, of the 30-minute-trip to his office in the centre of Shanghai. “I know the cost of driving is much higher than travel by bus,” he said. “But this way, I feel more comfortable and it is much faster.”
