During which意思
"During which" is a relative pronoun phrase used to indicate a period of time or a specific situation that is being referred to in a previous clause. It is used to connect two clauses and specify the time or context within which something occurred or was done.
For example:
- "She read several books during which she learned a lot about history."
- "The team practiced hard during which they improved their skills significantly."
In both examples, "during which" refers to the time period when the actions (reading books and practicing) took place. It indicates that the learning and skill improvement happened within the specified time periods.
