31、着中国建筑师”。文章开头提到，当著名的外国建筑师主持建造新的中央电视塔和国家大剧院时，中国建筑师开始努力登上(国际建筑领域的)中心舞台。而王澍获得有 “建筑界的诺贝尔奖”之称的“普利兹克奖”，意味着中国建筑师的努力有了回报，开始获得国际认可。6C事实细节题。根据第四段句首的主题句“The style of the campus is quite different from that of most Chinese universities.”及本段其他内容可知，中国美术学院象山校区给人留下的最深刻印象是其独特的建筑风格。7D推理判断题。根据文章第六段，1995年“普利兹克建筑奖”获得者Tad
