《2025年课堂作业武汉出版社八年级英语下册人教版》

Losing your phone is a pity, but I did just that when I got into a taxi and closed the door heavily. I heard a loud noise. It was the sound of my phone’s screen breaking. Besides the sound of breaking glass, the other sound I heard was my own voice saying, “Oh, no! What have I done?”
So, for the next day, I had to live without a phone: no calls, no texts, no social media. And what I discovered was that I really didn’t miss making phone calls or getting text messages or else. It was actually relaxing. For that whole day, I was able to stop living in a “virtual” world and start living in the “real” world.
★ . They are sources (来源) of communications, information and entertainment. All of these things are good, but too much of these things can also be bad. There is a chemical in your brain called dopamine (多巴胺). Activities like watching videos cause your brain to get this chemical. It gives you pleasure. For many people, these feelings of “pleasure” will increase as they use their smartphone more. This explains why you may feel upset when you can’t use yours. You have, in fact, become addicted(上瘾) to dopamine, the “happy hormone”. To treat this increasingly common addiction, some places are trying a life of “no digital hour”. In the Indian village of Vadgaon, for example, people are being forced to turn off their phones and TVs from 7 pm to 8:30 pm every night.
Smartphones are great, but you should be smart about using them. Put them away in your pocket for a while and enjoy the real world, but you should still be careful about getting into taxis.
