In short,dogs ___ cooked foods live shorter,less healthy and more painful lives.A.to be fed on B.having fed on C.fed on D.feeding on...为什么是被动关系
这里的fed on cooked food其实是过去分词短语修饰dogs的,因为狗是被喂养的(它不可能自己喂养自己吧),所以“狗”和“喂”之间属于被动关系.翻译起来就是“总之,吃煮过食物的狗活的时间更短,更不健康,过着更痛苦的生活”.
其实分词修饰名词主要是看被动或是主动关系,主动就用现在分词,被动就用过去分词.

完整的是dogs that are fed on cooked food live shorter...
that be可以同时省略,这样懂了?
望采纳~
