Last year, a group of elephants did something different-they (start) to go north! After(month) of traveling, elephants made it 500 kilometers away from their home in Yunnan."Asian elephants often stay in same place,"said Chen Mingyong, a teacher."It is very rare(少) to see them travel such a long way."
(science) are still not sure why elephants are doing this. Some people think that's they want to find better food. Some think there are more and more elephants, so their old homes may not have much food them. Others think elephants are (interest) in the vegetables, crops and fruits in the north. As we all know, elephants are so clever that they can find their favorite food(easy).
During(they) long journey, the elephants caused economic losses(经济损失) of nearly6,800,000 yuan. People used seventy-six police cars to keep them safe and gave food to keep them away from cities and towns. But elephants are still in(dangerous). We need to save them.
