本周推荐：《荒野上的大师》

作者： 张泉

推荐： 小编1号

这是一本读着读着就感慨不已留下热泪的历史记录。清末民初的时候，每个读书人都面临着艰难的选择。有一批读书人，走出了象牙塔，走进各种考古现场，进行挖掘和分析，开创了本土古生物研究、古建筑研究、古人类学的先河。在这些人之前，中国并没有这样的学科传统，仅有的考古学主要以碑文研究为主。第一批留学西方的读书人，迫切的希望寻找到自己民族的历史，民族的考古学证据，希望在备受屈辱的年代，重新找回历史悠久的自豪感；同时又不得不面对山河破碎未能投笔从戎的煎熬与困惑。

每当我徘徊在人生价值相对和虚无的边缘，总是能够有这样前辈学人出现，给我当头棒喝的清醒，让我能够继续笃定的前行。
