大家帮我看看这篇英语短文有没有问题

Riding the horse on the grassland
During the trip,I also had an unforgettable experience:riding the horse on the grassland.It was the first time I rode the horse alone.
The horse which would be ridden by me was a brown(and去掉) beautiful horse. And,it was very small, it was the smallest horse I have ever ridden. . At first, I was afraid of falling down from the horse. I was very nervous and couldn’t draw myself up.But, after nearly half an hour for(of) practicing(practice), I knew how to ride a horse. I began to ride the horse and enjoyed the warm sunshine happily.
I had a good time on the grassland.What a happy life the people there have!

提几个建议……
the horse I rid was brown and beautiful .What's more, it was so little that I never rid a smaller .
learn to 比know 更强调“学会”的意思
I had learnt to ride a horse .
结尾太刻意了，换一个自然点的。

我大概看了一眼，可能不太细致，但应该没有问题，望采纳哦
