seem都有那些使用方法

请问老师：

He seemed set on course to become just as reckless a godfather to Teddy Lupin as Sirius Black had been to him.

不应该是 seem to do sth吗？为何在这句话里不这么用？

He seemed set on course to become just as reckless a godfather to Teddy Lupin as Sirius Black had been to him.

【翻译】他好像正要成为小泰德·卢平的鲁莽的教父，恰恰就像小天狼星布莱克以前是他本人的教父那样。

【剖析】真的理解这个句子，它有两个要紧结构，需要弄了解：

1. be set on course：意为“正在规定的路线上；正在路上”；引申为“正要做某事；就要如何”。本句翻译为“正要”二字。

过去分词set 用作形容词，作表语。seem 是“系动词”，使用方法之一就是直接跟形容词作表语：seem + 形容词。如此seem 就代替了be，当然说 seem to be set on course 也可以，略嫌啰嗦。

2. as A to B as C to D：这是一个“比喻”结构。意思是：A对B而言，就像C对D一样。所以，本句翻译成：他成为小泰德·卢平的鲁莽的教父，恰恰就像小天狼星布莱克以前是他本人的教父那样。
