Question

有人能解释清这个句子吗?
1,he is an interesting speaker,and,w h i c h is more important,he knows his subject thoroughly.,
2,he went to the meating,and,w h i c h was worse,insisted on speaking.
两句都有Which,第一句还能理解,是非限定定从.第二句中的Which呢?能不能再举个例子说明下~
And 是不是没影响？

Answer 1

第二句的which 指代的是后面的“insisted on speaking”.(meating 应该是meeting吧）.这句中的w h i c h was worse 是插入语.
例如：He was sick and,which was worse,preparing for the coming exam.
