答案是c, 可是d为什么不行呢？c中不是把invole在句中的成分改变了吗？

D最主要的错误是that involves修饰了disease. involve应该是修饰diagnose的方法.

C的意思是正确的

不是说：

把句子的主干改成从属成分，从属成分改成主干就错了吗？

所以一看到invole变成谓语，就把它给过了。

这里为什么是正确的呢？

我感觉还是要看逻辑. 除了基本语法, 别太注重规则.

       agree!!

       i suppose many discussion in SC section is misleading.

       so far as i know, nearly 90% questions can be solved easily if one understands the real meaning of the given sentence.  

我也有同样confusion!另外，从句应该可以跳跃修饰，但分词不可以，对吗？

请大NN们给我一个答案
