用英语唱首歌怎么说

To sing a song in English, you can say “I’m going to sing a song in English” or “I’m going to perform a song in English.” Alternatively, you can simply say “I’m going to sing a song” and specify the language if necessary or relevant. For example, you might say “I’m going to sing a song in French” if you are singing a French song or if you are singing in a context where the language of the song might not be clear.
