Describe a person who has interesting ideas.
You should say:
• who this person is
• how you know them
• what ideas they have
• and explain why you think their ideas are interesting.

I'd like to talk about my uncle, who I think has really creative ideas. He's in his fifties and works as an engineer, but he's the kind of person who always looks at ordinary things in a different way.
I've known him since I was a child, because he's my mother's elder brother and we used to visit him every Spring Festival.
What strikes me most is his idea of turning our balcony into a small vegetable garden. He grows tomatoes and herbs in old buckets, and last year we actually had enough for the whole family.
I find his ideas interesting because he takes something that most people would ignore and makes it useful and fun. It taught me that creativity isn't about being fancy — it's about how you see the world.
