残り時間が少ししかないですが、もう一つ質問してもいい？って英語でなんて言うの？

As both you and the teacher would know the lesson is coming to an end, you can just say "is there time for one more/another question?". To indicate that you will be quick with your question and the answer will be short, you can ask "can I quickly ask one more/another question?".

"Can I ask one more question before our time's up?" - The English idiom "time's up" means the the period of time allowed for something is ended. In this sentence, the time for the class is coming to an end. Therefore, you are saying that you would like to ask one more question before the class ends. Example of Idiom: "Turn in your papers, students; time is up." "Can I squeeze in one more question before the end of our lesson?" - The word squeeze means to manage to get something into a restricted space. The restricted space in this case would be the amount of time remaining. Since there is very little time remaining for the class, it is as if you're squeezing in your last question before the class ends. Example: We all squeezed into Steve's van.

*Is it okay if I can quickly ask one last question?- This means you would like to know if it's okay with the teacher if you can or there is not enough time. *I know it's almost time but I have one burning question. Is it okay if I ask?- "I know it's almost time "- this means that you are letting the teacher know that you are aware that there is not enough time. "burning question'- this is an important or urgent question that requires an answer.

You want to ask if you can ask a question as there is only a minute of the lesson left? Well, if there is a minute left, then just ask the question. If you ask someone about asking a question, then you are just wasting time!

If you are in a lesson and time is almost finished, but you want to know if you have time to ask one last question, you can ask "Do we have time for me to ask one more question?"

If you only have a minute left of the lesson but want to ask another question then by saying 'We only have one minute left' you are letting the teacher know that you know there is not much time left so you would add ' but can I ask another question?' You could also ask 'Is there enough time for me to ask another question?' this is a polite way of saying you know but the time but want to ask a question you could also say ' can I quickly ask another qustion?'

When you want to ask the teacher if you can ask one more question (before the end of the lesson), then you may ask?say it in the following ways: -May I ask one more question? -I have one more question. -I have another question...
