如果你想要提问外国人，你可以使用下面的句子：
Could you please answer my question?
Do you mind answering my question?
Can you help me with this question?
I was wondering if you could help me with something.
I have a question for you.
注意：在提问之前，应该先询问对方是否愿意回答你的问题。这是礼貌的做法。
例如：
"Could you please help me with this question? I'm not sure how to proceed."
或者：
"Do you mind answering a quick question for me? I'm just trying to understand this concept better."
