概述：本道作业题是乐道睬同学的课后练习，分享的知识点是eaten，指导老师为贝老师，涉及到的知识点涵盖：eat的过去分词是ate还是eaten？perfectparticiple和pastparticiple...-eaten，下面是乐道睬作业题的详细。
eaten
past participle不是一个时态, 而是一个动词变化型, 就是过去分词, 如go-->gone, cut-->cut want-->wanted 这些
past participle主要用於三个情况,
~第一, 是用於perfect tense, 在have, has, had之后的动词就用past participle
~第二个是在被动句(passive voice)里, 在be (即am, is, are, was, were)之后的动词要用past participle
~第三个是将past participle作形容词用, 例如: The burnt house is gonig to be rebuilt
当然是ate了！
