As we all know,the slavery played an important role in the history of America. I think that everyone who went through it would remember it throughout their life. When we visited the national underground railroad freedom centre yesterday, I was impressed by the miserable experience of slaves and their courage of seeking the freedom. Freedom means that you can do anything you want, go to anywhere you like. I can't imagine how to live without freedom, it's very very terrible. I feel very lucky that our ancestors fight to abolish slavery, and set the slaves free, so today, we can live in this world happily and freely. The burning flame is the symbol of freedom, I hope this flame will go on forever.
This afternoon, we visited the Ohio historical society, it's really ery interesting to see so many artifacts. I was mostly impressed with the large Mastodon skeleton in the main gallery.
Also, there are so many plants, animals, ceramics,
furniture, woodenware, and metal ware. A wonderful village attracted us the most. People in this village told us stories in the past years, and tried to imitate life in the past to all of the visitors. I think history is the best textbook to show people how our ancestors worked hard to make a better life for their children and children‘s children. We also can learn some valuable experience from them to make a great advance.
