Researchers believe that the insect(昆虫) is better at managing congestion (拥挤) than humans. Ants are the most many type of animal on earth with brains that contain about 250,000 cells ---- the largest among insects.
Now an intelligence expert Dr. Dirk Helbing says understanding more about ants could help solve one of the headaches of modern life -- road congestion.
His team set up an "ant motorway" with two routes of different widths from the nest to some sugar syrup (糖浆). Soon the narrower（更窄的） route soon became crowded（拥挤的）. But when an ant returning along the crowded route to the nest met with another ant just starting out, the returning ant pushed the newcomer onto the other path. However, if the returning ant had enjoyed a trouble-free journey, it did not send the newcomer in a different direction.
The result was that just before one route became clogged , the ants had turned to another route and traffic jams never formed.
The researchers also created a computer model of more complex ant networks with routes of different lengths. The team found that even though ants being sent in another direction sometimes took a longer route, they still got to the food quickly and efficiently.
Dr. Helbing, of the Dresden University of Technology in Germany, said that while you cannot allow cars to meet with traffic coming in the opposite（相反的）direction as a form of traffic control, you could do the next best thing and allow them to communicate.
His plan is to force cars traveling in one direction to tell oncoming traffic what the conditions they are about to meet with-- so they can avoid that situation if necessary.

Garden building is considered an important part of Chinese culture. Some people say that if you have never walked through a Chinese garden, you cannot say that you have really visited China.
Traditional Chinese gardens are located in North China in such places as Beihai Park, the Summer Palace, the Forbidden City. In larger imperial gardens, the main buildings are connected by an imaginary（虚构的） line in the middle of the garden on the north-south axis(轴). Other features of imperial gardens are colored-paintings, man-made hills and lakes.
Most private gardens are found in the south, especially in cities south of the Yangtze River. Private gardens were mostly built at one side or at the back of the houses. Around the beautiful scene are small open areas with beautiful shaped-doors through which visitors can enjoy the sights. They are open on all sides and are often near the water so that the whole scene can be enjoyed. Suzhou, known as the home of gardens, displays the most and the best Chinese traditional private gardens. Different parts of it are examples of the garden style of the Song, Yuan, Ming and Qing Dynasties.[
The landscape（自然风景） garden contains a number of pleasant natural scenes and some fairy tales. The ancient Chinese used to call the garden landscape “Jing” , which means “scene” in English. Good examples include the ten West Lake Scenes in Hangzhou, the twenty-four slim West Lake in Yangzhou and the eight Daming Lake Scenes in Jinan.
