S1. John [was] eaten by lions
First sentence，in my humble opinion, it means the event happened in past. The sentence 'John
has been eaten by lions' indicates that it happened in past and still remains as a fact until now.
S2. I [have] eaten my dinner
It means you mention that you have taken your meal at the point you spoke it out. Alternatively, 'I
had eaten my dinner when the bus arrived' emphasis that you have finished your dinner before the
arrival time of the bus. 作者: czhi 时间: 2016-2-13 04:55 PM

first sentence is past tense+passive, so use was/were+verb(past tense)
second sentence is present perfect tense+active, so use have/has+verb(past participle)作者: Dejavu-247 时间: 2017-3-9 07:02 PM
还有你的单数复数问题也很严重。
