A Visit to the Great Wall
Have you ever been to the Great Wall? I have ever been there. That was a sunny day. My friends and I took a bus to the Great Wall. When we got to the foot of the Great Wall, we saw a lot of visitors. We began to climb the Great Wall. A t this time, .We found the Great Wall is very ,very long and beautiful. It is like a huge dragon. It is said that it is one of the New Seven Wonders in the World. And the most famous wall is the Badaling Great Wall.
I was excited when I got to the top of the wall. Though we were tired, we all felt very happy. 以描述海南岛为例：
Have you ever been to Hainan Island? It is the second largest island in China.
It’s a beautiful place. If you go there, you should walk along the beaches. The weather in Hainan is very hot, so people like doing many water sports, such as diving (潜水), fishing, swimming, surfing and boating. One great thing about Hainan is that you can try many kinds of sweet fruit in Hainan.
If you go to Hainan, I’m sure you will enjoy yourself.

color. It’s special to me because my grandmother made it for me. I think I will keep it forever, to remind me of my grandmother.
The teddy bear has given me many good memories. I remember
