记得够钩里好像提到了下面这一段，估计没有考点，所以楼主没有印象了。 Like a French child raised byEnglish-speaking parents, a young songbird raised by a different species ofadult, or with recordings of a different species, will end up learning the“wrong” song—and will produce only an odd, improvised tune if it is raised inisolation. A vocal nonlearner such as a phoebe or a dove, on the other hand,will sing its species’ correct song even if it’s brought up by another kind ofbird, or by none at all.
