Our home is slowly turning into a smart home, thanks to all kinds of cool smart devices. Here are some of the ones I enjoy using the most. First, our smart lights are amazing. I can control them with my phone or just my voice—no need to get out of bed to turn them off on a cold night! What’s really cool is that I can change their brightness and colours. For example, I set them to soft yellow when my kids are listening to bedtime stories and bright white when they are doing their homework. Last night was our family movie night, and we set the lights to soft blue, which made the room more comfortable. Next, I’m a big fan of our smart door lock. Remember those days of searching for keys in the dark? Gone! Now, we can lock the door with a code (密码), or even our phones. And the best part? We can create temporary codes for guests, so we don’t have to worry about giving out another key. These codes will stop working after the guests leave. We also have a smart camera inside the house. It’s mainly for checking on our dog when we’re not at home. We can see what he’s doing, and sometimes, we even talk to him through the camera! It makes us feel connected to him. The smart camera is really perfect for those with pets. These smart devices are not just tools. They’re like helpful friends. They teach me that technology can bring both joy and safety to our daily lives. 1．What colour are the lights when Jessica’s kids are doing their homework? A．Soft yellow. B．Soft blue. C．Bright white.
