An earthquake（地震）can make buildings to fall down.Rescuers look through the rubble（廢墟）to find people and try to rescue them，but it's not easy.
   Luckily，there's a new way to do it now.A Dutch group has made a special bag.It has a camera and a two-way microphone.They train（訓(xùn)練） African giant pouched rats（非洲巨頰囊鼠） and wear the bag on their backs，and then the rats can search for people in the rubble with the backpack.
   The idea is that the rats can get into small places.When the rat is searching a place with the bag，human rescuers can watch a live feed（現(xiàn)場(chǎng)直播）.The live feed lets rescuers see if someone needs help.
   Donna Kean is working on the project.She says that rats are perfect（完美的）for the job because they are usually quite interested in new things，and they like to run everywhere.Together with the bag and the training，the rats are very useful for search and rescue.
