The problem is becoming more and more serious. We should do something to prevent it.

　　First, I think we should have more police officers at the busy crossings. They can stop the traffic jams (阻塞). Second, we should not make more parking garages (停车位) for cars. When people think that it's easy to park in cities, more people will drive to work and it will make the traffic more crowded. Third, we should make it more expensive for drivers to drive cars to cities. Then more people will leave their cars for their bikes. Fourth, we should encourage people to take a bus to work. Fifth, we should build special ways for bikes so that more people will go to work by bike instead of by bus or in a car. Finally, we should spend more on the public transportation (公共交通). For example, we can build more underground lines. Of course, we can also do many other things to improve our traffic.

The giraffe is the tallest modern land animal. It can be over 5. 5 meters tall. Its neck alone may be 1. 9 meters long. Yet the giraffe has only seven bones in its neck, the same number as in the humans'. Even a small bird has many more bones in its neck than a tall giraffe. Each bone in a giraffe's neck is very long, while the bones in a human's neck are short. That makes the difference. A female giraffe gives birth to one baby at a time. The baby, called a calf, is about 1. 9 meters tall at birth. By the age of eight it is full-grown. The giraffe eats mostly leaves. Because it has a long neck, it can reach the high leaves on the trees.

　　Tigers are strong and dangerous animals. But now they are in danger.

　　In the past, there were eight kinds of tigers in the world. But during the 20th century, only five were left. The number of Siberian tigers (东北虎) was about 300, but now it is less than 22. They're in danger of dying out. If the government does nothing, we won't be able to see them in ten to twenty years.

　　In order to stop people from hunting and killing wild tigers, and in order to make wild tigers more, the World Wildlife Fund (世界自然基金会) has started a program (项目) recently (最近). China and twelve other countries joined it.

　　However, it's not enough. Remember that nature is a food chain (链). If we hurt and kill too many wild deer and pigs, wild tigers will die out because of hunger (饥饿). So the most important thing is to save the animals that tigers eat. In order to protect the wild tigers, we need call on (号召) more people to stop eating, hunting and killing wild animals.
