In the USA，each year，students take part in a kind of competition called the Science Olympiad．
It has a lot of different events．Students go there to show how much they know about the science of music，biology，chemistry and others．My best event is forestry．
The big day came at last!First，I went to watch the tower building competition．That's when students build small towers and put heavy things on top of it．They hope they can hold them up．One of my schoolmates was putting things on her tower．She was nervous，and in the end it was too heavy for her tower to hold it﹣﹣﹣it broke!I felt bad for her．
After lunch，I helped some teammates with their events．One was geography，and the other was history．I don't know much about those things，so I just watched my teammates do most of the work．
At last，it was time for my favorite event﹣﹣﹣﹣forestry．The rules were easy．We had to look at more than 40different kinds of leaves and find out which plants they were from．We also had to answer some questions about the uses of each leaf.1knew almost all of the leaves and could answer most of the questions．I had spent more than a month studying on the Internet to get ready．At the end，it was time for the awards（颁奖）．I was nervous，because the forestry awards were last．We won second place in the whole state!A nice man gave me a medal and smiled at me．

Do you know the story about Vince? It was a true story. Vince was an English boy and he was eight years old. He didn’t like soap or water. Three or four times a day his mother said to him, “Vince, your hands are very dirty again.” Go and wash them. ” But Vince never washed them well. He only put his hands in the water for a few seconds and then took them out again.
Vince’s uncle and aunt lived in another city. One day they came to stay with Vince’s parents, and they brought their small son, Toby, with them. Toby was seven years old and he didn’t like soap or water, either.
The boys sat with their parents for a few minutes and then they went outside. When they
were playing, Vince looked at Toby’s hands and then went back to Toby’s parents and said proudly (骄傲地)， “Toby’s hands are dirtier than mine, ”

Both of the boys disliked soap or water.

We all got up early and got dressed quickly. And then we went to the airport by bus. We went back home on a very big plane. On the plane I sat with Linda and my dad. Dad was in the middle and I was by the window， so I could see everything. Junior was behind us. I played with Linda for a while and then went to sleep.
When we got off the plane， it was very cold. We all had to hold hand baggage (托着行李) on the way home， because we brought back so many things.
I think the vacation is very nice. It is really interesting to visit Hainan and we all had a good time there.How did the family go to the airport?
