[过15分钟用英语怎么说] The correct answer would be "In 15 minutes" in English.
In English, when expressing a specific time in the future, we typically use the preposition "in" followed by the duration or time period. So, "in 15 minutes" means that something will happen 15 minutes from now. It is a concise and clear way to indicate an estimated time in the near future.
In everyday conversations, this phrase is commonly used when making plans or arranging meetings, especially when discussing a specific time frame. For example, if someone asks, "When will you be ready?" the response could be "In 15 minutes," meaning that they will be prepared within the next quarter-hour.
It's worth noting that while "in 15 minutes" is a commonly used phrase, it doesn't have to be limited to 15 minutes specifically. You can replace "15" with any other number to indicate a different time frame, such as "in 10 minutes," "in 30 minutes," etc. This phrase provides a straightforward and efficient way of expressing the time in English conversations.
