昨天讨论的问题十分重要用英文怎么说

The phrase "the matter at hand" is often used to refer to something that is important and currently being discussed or dealt with. It comes from the idiomatic expression "to have one's hand in the matter" which means to be involved in something.

例句:

"The matter at hand is the budget for the upcoming fiscal year." (目前讨论的问题是即将到来的财政年度的预算。)
"Let's stay focused on the matter at hand and not get sidetracked." (让我们专注于目前的问题，不要被分心。)
"The matter at hand is of the utmost importance and requires our immediate attention." (目前的问题非常重要，需要我们立即关注。)
