having been done的用法

完成被动进行
再问：知道，能举个例子吗？它跟done 有什么区别？
再答： Having been kept in the fridge for two hours, the food has gone bad.
再问：那这样跟，Not invited，he felt very unhappy有什么区别呀？
再答： 1）having been done一般强调被动的动作，而且该动作必须和主句动作之间有着明显的时间/逻辑上的先后/因果关系，且隐含having been done的动作不会再进行的意味。 2）done做状语时更多时候强调的是一个可以延续的状态，而且它所表示的情况可以和主句动作同时存在。）Having been kept in the fridge for two hours, the food has gone bad. 此题强调先有“be kept in the fridge”，才导致了后面的“go bad”. 前后动词有明显的先后/因果关系，且隐含了“这食物不会再放在冰箱里保存”的含义了。 2）Frightened by the news, he felt dizzy. 其实frighteded by the news是由“he was frightened by the news”变化而来的，强调的更多是一种状态。其实在“他感到眩晕”的同时，他还在“感到害怕”。
