Chomsky's grammar should show patterns of language change that are independent of the family tree or the pathway tracked through it, whereas Greenbergian universality predicts strong co-dependencies between particular types of word-order relations.
这里的定语从句that的先行词是patterns,如果不根据that后面的are来分析,还有没有别的办法了?我的意思是如果A of B 这两个单词都是单数,又应该怎么判断先行词呢?
