I'll never forget the day when I went on a hot- air balloon trip. It was a birthday gift from my aunt.

I had to 1 early, but it wasn't a problem. I couldn't sleep because I was so excited.

My parents and my aunt came to 2 . They waved (挥手) as I got into the balloon. There were five other people and the pilot (飞行员) in it. When we took off, it was quite 3 and I couldn't hear anything. Then it became much quieter, I can't describe the 4 . It felt like a dream. The sky was blue and clear. I could see all the people below us. They were getting smaller and smaller 5 we got higher and higher.

6 , a rainstorm began! The balloon started to drop. The pilot decided to land as quickly as possible, but he couldn't control (控制) the balloon. The wind was 7 us to the sea. It was very scary (吓人)!

Very soon, the 8 changed direction and we were finally able to land on a hill. We got out of the balloon. Luckily, no one was hurt. I could walk back to my 9 and show them I was OK.

Was I 10 ? Yes, a little. Will I ever do it again? Not sure!
