标题: 定语从句和分词的区别。
In many cases, a relative clause (a clause headed by a relative pronoun) and a present participle odifier are practically interchangeable.

Right: The man WHO ISCLEANINGthe steps is my uncle.
Right: The man CLEANINGthe steps is my uncle.

However, consider these examples:
(A) The rate of language extinction is accelerating, a tendency ultimately culminating in the survival of just a few languages, according to some.
(8) The rate of language extinction is accelerating, a tendency that will  ultimately culminate in the survival of just a few languages, according to some.

最后两句话，是在说因为主语用的是进行时态，所以修饰成分不要用分词修饰？还是说分词有时候表达不出来一些时态上的subtle 差别？

其实没有区别~如果你把C改成jumped，也对。但是相比之下，B更简洁一些。

二者有区别的时候，主要是以下几种情况：
限制性修饰VS 【无逗号V-ing定语结构】：                                      
A)前者如若有情态动词不可换成后者；                                                
B)如果修饰句和主句想表达与主句时态不一样的情况，用前者。                    
C)在法规后一般用后者，强调多次重复性的感觉。

嘻嘻，找到解释了。

上面的问题可以用B来解释。
