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.
这类句子都源于1本语法书。红色的it指是Sam is an indirect还是the direct object?我感觉是the direct object，但这本书后面说：想强调行动收益的人时，用subject + verb + direct object + for/to + noun or pronoun句型。
图片是书的截图，红框地方矛盾了吗？谢谢老师~~
红字的it指的是间接宾语。书中最后已经说得非常了解了。
记住，句末是信息中心。
Give sb sth. 突出sth.
give sth to sb 突出sb。
书中说得非常了解，没矛盾。
