"要问的问题" 的英文表达是 "the question(s) you want to ask".

这个表达是基于英文中 "want" 这个动词的含义来的。"Want" 在这里表示有意愿、有需要或者有兴趣去做某件事。例如:

"I want to go to the store." (我想去商店。)
"She wants to learn how to play the piano." (她想学弹钢琴。)

所以,"要问的问题" 就可以被翻译为 "the question(s) you want to ask"。

下面是一些例句:

"What are the questions you want to ask the speaker?" (你想问演讲者什么问题?)
"Before the interview, make a pst of the questions you want to ask the company." (面试前,列出你想问公司的问题。)
