saw 和 yet ？

Global markets were reeling Monday after a convulsive day on Wall Street that saw a leading U.S. investment bank file for bankruptcy and other institutes scramble to merge as the credit crunch claimed one of its biggest victims yet.
that saw我觉得应该是修饰的a convulsive day，see有发生的意思吗，还是拟人化的手法？这种用法能否举个例子。
yet是指迄今为止最大的受害者吗？暗指可能还会有更大的？
感谢两位回答，我觉得总要能从语法上说的过去才行，that saw作为从句不管是定语从句还是什么从句，要能和前面的成分有主谓关系或其它关系才对。saw逻辑上的主语是什么？如果是省略了人们似乎不应该加在名词后面用that来引导。如果说为了临场感，他的主语是谁?

either和yet区别 yet和already的用法 ever和yet的区别 either和yet的区别 怎么区分still和yet？？？？ yet和 just the same just yet的解释和用法 still 和yet用法有什么不同 just和yet能同时出现吗 not……yet 意思是否和 一个yet一样啊？
