There exists certain degree of similarities between industrial clusters and species population.
这里为何是 of similarities 修饰 degree?
A of B中怎么分辨哪部分修饰哪部分?如a number of B,这里是A修饰B;the number of B,这里是B修饰A。
写错了句子,会致使语法错误。就算是一个小小的冠词,也应该注意。网友漏掉了一个重点的冠词(涉及你的问题):
There exists a certain degree of similarities between industrial clusters and species population.
表示“量定义” 的名词前用了冠词 a,比如:a cup ofcoffee, a number of books,acertain degree ofsimilarities,这个时候,划线部分一般看作“限定语”(定语),后面的名词为“中心词”。假如不定冠词,换成特指的定冠词the,那样中心词一般随之转移至这个量词上,of ... 作定语。比如:
the cup of coffee,
the two cups of coffee (假如作主语,要用复数。也充分说明中心词是cups)
the number of my books
