答案

首先确定 I won't come to the party unless Tom is invited 是否定句,只有 either 可以作为强调成分用在否定陈述之后.
问题出在 either 究竟是强调 I won't come to the party（我也不参加聚会）还是强调 unless Tom is invited（如果汤姆也没受到邀请）.
如果属于口语,可以通过语调的轻缓知道是 “也不参加” 还是 “也没受到邀请”.但是在书面语中,把 either 置于句尾,如果缺乏更具体的语言环境,就会产生歧义.
因此,就孤立的句子而言,根据强调的不同,这个句子应该调整如下：
　　Unless Tom is invited,I won't come to the party,either.
　　Unless Tom is invited,either,I won't come to the party.
