Answer 1

Mr. Smith told me that he (would) (visit) the palace museum the next day.
填would表过去将来时，因为Mr. Smith是在过去某一时刻告诉我他的计划。

过去将来时的构成:
肯定句：主语+be（was，were）going to+动词原形（v.原)+其它
或：主语+would（should would）+动词原形+其它
或:was/were+动词不定式

例句:
She told us that she would not go with us，if it rained.
她告诉我们，如果下雨的话，她就不和我们一起去了。

He told me he would go to Beijing.
他告诉我他将去北京。
