Even within national contexts, studies have found more support for the density dependence model when they employ broader geographic units of analysis--for example, finding that the model's operation is seen more clearly at the state and national levels than at city levels.
现在正在精读prep,这句话看了很多遍都理解不了。希望各位NN帮我解答一下啊!
they是做的studies的代词吗?为何觉得有点怪怪的-。-
dash后面的成分应该如何理呢? for example 指的是哪个部分呢?
finding修饰的是前面整句的话,那它的逻辑主语是studies还是they啊?它修饰的V是have found还是employ呢?
很崩溃,求助
