同学你好~
would可以表示相对于过去的将来
He said he would be here at eight o'clock.
他说他将在八点钟到达这里。

would用于指过去的意愿
He asked if I would show him the way. 他问我是愿意可以给他带路。

would均可用于征求意见或提出请求，此时的would并不表示过去，而是为了使语气更委婉。
Would you ask them to wait outside? 你可否请他们在外面等等?

would有时用于提出想法，通常与like, love, hate, prefer, be glad, be happy等连用。如：
I would like to make a suggestion. 我想提一个建议。
I’d love to have a room of my own. 我想有一个自己的房间。

would表示过去的习惯。
When we were students we would often stay up all night. 我们当学生时，经常通宵不睡。

would用于推测过去，但也可用于推测现在，只是语气比较委婉、比较不确定。
You wouldn’t tell anyone, would you? 你不会告诉别人的，对吧?
That would be the watch you are looking for. 那大概是你在寻找的手表吧。

祝同学学习进步~
