请高手来看一下这句话的修改!!!

he often came to my office at night to discuss the questions he had come across or his opinions with me.

觉得有点别扭,看如何在保持原意的前提下修改最好?

he often comes to my office at night to discuss the questions he has come across or exchange opinions with me.

he often come to my office at night to discuss the questions or his opinions with me.

可以这么说，没有语法错误。以下是我的观点，仅供参考：

He often comes to my office at night to discuss with me on the questions he came across or his opinions .

He often came to my office at night to dicuss the questions with me he had come across and xchange his opinion with me. 第三人称单数he often 后的come 要加s eg:She usually listens to me.with 是指和某人一起 come across不用变,是指discover something by chance,如你用一般现在时最好,他是从前常和你商量?

He used to come to my office at night frequently to discuss questions he had come across or his opinions with me

如果你想表达的是过去式的话，就用上面那句，如果说他现在还是那样做的话，就是He often comes to my office at night to discuss questions he has come across or his opinions with me

如果用questions前面就不用加the了

这怎么看起来像骚扰...汗

Often 一般用在一般现在时,我觉得改用USED TO 更好一点
