The firm gave Sam a gold watch.
Sam is an indirect object. However, the direct object can come after the verb if we wish to emphasize it.When this is the case, the
indirect object is replaced by a prepositional phrase beginning with to or for:

The firm gave a watch with a beautiful inscription on it to Sam.
這類句子都源于1本語法書。紅色的it指是Sam is an indirect還是the direct object?我感覺是the direct object，但這本書后面說：想強調行動收益的人時，用subject + verb + direct object + for/to + noun or pronoun句型。

圖片是書的截圖，紅框地方矛盾了嗎？謝謝老師~~

紅字的it指的是間接賓語。書中最后已經說得非常了解了。

記住，句末是信息中心。

Give sb sth. 突出sth.

give sth to sb 突出sb。

書中說得非常了解，沒矛盾。
