    阅读下列材料,回答问题:
    甲骨文距今约3600 多年的历史。那时候的统治者迷信鬼神,其行事以前往往用龟甲兽骨占卜吉凶,以后又在甲骨上刻记所占事项及事后应  验的卜辞或有关记事,其文字称甲骨文。自清末在河南安阳殷墟发现有文字之甲骨,整整100 年了, 目前出土数量在15 万片之上,大多为盘庚迁殷至纣亡王室遗物。  以出至殷墟,故又称殷墟文字;因所刻多为卜辞,故又称贞卜文字。甲骨文目前出土的单字共有4500 个, 已识2000 余字, 公认千余字。它记载了三千多年前中国社会政治,经济,文化等各方面的资料。是现存最早最珍贵的历史文物。请回答下列问题。
    (1)看下列图片是甲骨文中的十二生肖中的部分文字,你可知道分别是什么吗?写在横线上。 
    (2)看下图甲骨文中的各种”,形状均似丝线缠绕。请你在图上用笔圈出这个字。通过这片甲骨文上的丝字,你能推测出一个什么样的结论?
