示范答案：
I usually sleep around 7 to 7.5 hours each night—this seems to be the sweet spot for me to feel rested and focused the next day.
During weekdays, I try to stick to a consistent schedule: I go to bed around 11 PM and wake up at 6:30 AM, which fits with my work/study routine. On weekends, I might sleep in a little later, until 8 AM or so, but I avoid oversleeping too much because it disrupts my sleep cycle and leaves me feeling groggy.
