课本第3页:“山顶洞人已开始采取磨制和钻孔技术,制造石器、骨器,会制造骨针,把兽皮缝成衣服。”这一表述很容易使人误以为山顶洞人“开始”采用“磨制”技术制造石器。事实上,山顶洞人只会采用磨制技术制造骨器,还不会采用磨制技术制造石器。1975年第12期《文物》发表了一丁先
Textbook page 3: “The people in the cave have begun to adopt grinding and drilling techniques to make stone tools and bone devices. They will make bone needles and sewn the skin into clothes.” This expression makes it easy to mistakenly believe that the people at the top of the mountain have started. “Milling” technology is used to make stone tools. In fact, people at the Peak Cave will only use the grinding technique to make bones, and they will not use grinding techniques to make stone tools. The 12th “Relics” was published in 1975.
