范文：
In everyday English, the phrase "very uncommon" is often used to describe something that is not frequently encountered or seen. This term can be used in both formal and informal contexts to express the rarity of an object, event, or situation. For instance, if you're talking about a rare book that is found in only a few libraries around the world, you might say, "That book is very uncommon; it's a real treasure."
Here's a brief example sentence using the phrase in a conversation:
"I've been looking for a vintage camera, but it's proving to be very uncommon. I can't find one anywhere."
