　　“小耗子,上灯台。偷油吃,下不来……”In most people's view, rats are bad animals. They steal food from human beings, destroy crops and spread disease. In fact, rats can be of help and they have helped humans a lot. 许多科学实验都是用老鼠来做实验动物的。一种新药被发明出来后,也要在老鼠身上实验成功了才能给人类使用。Recently in Colombia（哥伦比亚）, six rats are being taught by police to search for bombs. The rats have been trained for a year. They will go through another six months' training. 和狗比起来,老鼠很轻,不会引爆炸a8a8弹。但要培养他们的忠诚可是件让人挠头的事。

　　If these rats graduate successfully, Colombia will probably be the first country to use rats to do police work. Just imagine rats and police working together！
