风扇在天花顶英语怎么说

In English, a fan that is mounted on the ceiling is called a ceiling fan. The term comes from the fact that the fan is attached to the ceiling and hangs down from it. Here are some example sentences in English and Chinese:

I installed a new ceiling fan in the living room to keep the air circulating. (我在客厅里安装了一个新的天花板风扇来保持空气流通。)
Do you have a ceiling fan in your bedroom? It can help you stay cool on hot nights. (你卧室里有天花板风扇吗？它可以帮助你在热夜保持凉快。)
The ceiling fan was making a loud noise, so I had to turn it off. (天花板风扇发出了嘈杂的声音，所以我不得不关掉它。)
