B. 高考应用文写作（参考范文）： Before my seven-day digital detox, I checked my phone whenever I had a free minute and often delayed homework. During the challenge, I turned off unnecessary notifications and kept the phone outside my study area. The first two days were difficult, but I gradually became less distracted and finished tasks more efficiently. I also slept earlier because I stopped scrolling before bed. The experience showed me that technology itself is not the problem; the key is how I use it. I will continue setting clear limits on screen time. $
