Tom seemed to have learned the news.
不定式中谓语是过去式,不定式就用完成时对吗

不一定哈,最好不要这样理解.这里的不定式其实就是seem to do .至于为什么用have learned是因为现在完成时态其实是现在时和过去时两种时态的结合.表示已经做过某事并强调对现在的影响是现在知道了news.
如果这里改为tom seemed to learned the news 意思就是tom似乎知道过消息用过去时只表示过去发生的动词现在还知不知道这消息是不清楚的说这句话的人的意图肯定是想表达那个人好像知道了消息而且现在也知道所以这里用完成时态更好些不是说不可以用过去时态seemed to learn.给你一个简便的方法就是做题时候如果翻译为已经做了某事的话就最好用完成时态本句的意思是tom似乎已经知道了这个消息希望对你有用哈
