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.
2对。unless为否定词，所以句末用either。too只用在肯定句中
判断：第二句对的
理由：其实就是区别too,either：too用于肯定句，在句尾；either用于否定句，也用于句尾。
第一句是对的
too 连接的是 I am invited and Tom is invited, too.
2是对的，因为在否定句式中TOO要换成either，虽都是也，但句式不同，所以用的地方也不同
