It was so suprised that I cannot closed my mouth. I was opened my mouth all of the day. I discovered the most important newfandle. That was the most big machine that I had ever seen. I took the picture and upload to the computer. All of the people said it is the "Time Machine". I was so curious about the Prehistoric Age. So, I decided to travel the prehistoric age.

When I go to the prehistoric age, I was changed into the prehistoric people. Also I do some works with other people and my friends. It has many differences with the work that we were doing in the future. We collected the fruits and some vegetables. I saw the tools that people used. It was so strange and also I think the people is smart to think about cut the animals skin with the tools and can cut the acorns and the foods with the tools. The tools that I think that was the best thing was the comb-pattern pottery. It was so useful to cook the foods and storage the foods. They point the bottom make it easier to keep them upright in the sand, because they lived near the sandy river side. And also I was interested in the grindling stone and stone pestle. Neolithic people ate many meal of the acorns. It was useful to grind or pound the acorns. Last, I was interested in the pit house. During the Neolithic period one family ate and slept in one small room. In the middle of the house it was kitchen. They cook the food in the middle. And the edge of the pit house people made the hunting and the cooking tools.

Today I learned about many types of the prehistoric and we can felt we have to memorize and respect the prehistoric age tools and people.
