请问quarters在这句话里是什么意思? 原句是"We are justtrying to help here," she says."I have heard that refrainfrom too many organizations and too many quarters wherethat help is actually doing harm so,I'm under no illusion that just thewill to do something good (is) enough. 别的都可以理解,就是quaters似乎从字典里找不出适合语境的解释,请问怎么解释好呢?
