It can tell the time, count my steps, and check messages from my parents. I use it to listen to music when I walk home. I like it because it is like a mini‑computer on my wrist. Without it, I would have to carry my phone everywhere. Part 2 I recommend you to try a robot cleaner. It can clean your floors automatically and even empty its own dustbin. It saves you time because you can do other things while it works. One day, I hope it will also mop the floor and climb stairs. It would make housework so much easier. Part 3 High technology has made our lives more convenient in many ways. For example, VR glasses let us take virtual trips without leaving home. However, it also brings some problems, such as privacy concerns and less physical activity. I think we should enjoy the benefits but also stay aware of the risks. Finding a balance is key. 1 学科网（北京）股份有限公司 $
