1998年暑假 ,我与妻子到美国西北部爱达荷州的博伊西 (Ｂｏｉｓｅ)探亲。 7月的一个下午 ,我们到已经定为重点保护历史遗址的爱达荷城 (ＩｄａｈｏＣｉｔｙ)参观 ,这里仍然保持着 1 9世纪中叶古色古香的风貌。据工作人员介绍 ,1 9世纪 60年代初只有 1 2人进入这处深山老林开发 During the summer of 1998, my wife and I went to visit Boise, Idaho, in the northwestern United States. One afternoon in July, we visited IdahoCity, a site that has been designated as a key conservation historic site, which still retains its antique style of the mid-19th century. According to the staff, only 12 people entered the deep-forest development in the early 1960s
