A series of questions did not give the professor a chance to breathe, even such outrageous questions as "Please introduce the sexual and moral conditions of human beings at that time" were asked, during which the professor introduced the living conditions of Neolithic people, who hadatural phenomenon? Is it a masterpiece of extraterrestrial civilization? The question has finally been brought to this topic of interest to everyone. I don't think so. There is no evidence of the existence of extraterrestrial civilization. We should explore the reasons for all this with a scientific attitude,interactive digital whiteboard, instead of attributing it to extraterrestrial civilization when we encounter unexplained phenomena, which is irresponsible. / 4 / The Mystery of the Site (4) "What do you think of the'Alien Base 'on Baigong Mountain, not far from here?"? Will there be a connection between the ruins and the'alien base '? "Sorry, I've never heard of the'alien base 'you're talking about." …… Three and a half hours passed quickly in a warm atmosphere, and new reporters kept coming. The scene was packed,smart board for conference room, and no one had any intention of going to dinner. And Professor Wu's interest became quite high. He just ate a few mouthfuls of bread, drank some boiled water, and took reporters to visit their excavation site. He was probably used to this kind of life. There is nothing special about the No.1 and No.2 pits. Probably every Neolithic site will have similar discoveries. The key lies in No.3 and No.4. No. Pit. The professor said as he carefully walked around the excavation pit of the site. The reporters formed a long line of two or three people behind him. On the edge of the pit numbered three, I saw a pile of black things, which looked nothing special except a pile of dirty garbage. Professor Wu motioned for everyone to touch the pile of things. I crouched down, touched it, then twisted the black particles on my hands, and put them in front of my nose to smell it. Sure enough, interactive whiteboard for schools ,smart board touch screen, it was the smell of rust. Because I was at the front of the line, it was very convenient to take pictures and ask questions. This is the iron they used at that time? What can they be used for? "Based on their shape, we initially judged that they were probably something like plows and shovels." I kept pressing the shutter ontern on it-to a layman like me, it seemed to be a human figure and some geometric lines that I couldn't tell what they were, and there was nothing special about it except the simplicity of the drawing. As long as it is related to this mysterious site, it seems to become magical. Things started to get interesting for a curious person like me, and it seemed to be going in the direction I was expecting. But who knows,smartboards in classrooms, this is not the case. It was not until nearly 3 p.m. that we searched almost every inch of the site except the area being excavated and forbidden to enter. When my digital camera had to be replaced with spare batteries and memory cards, we gradually dispersed and went to the tent to fill our stomachs. The reporters who took the late flight and ate in Delingha arrived late. It seemed that their journey was not very smooth. They regretted missing the interview in the morning. At this time, they were busy rushing to Professor Wu's office to catch up. / 5 /。 hsdsmartboard.com
