无论雨天还是晴天，每周四的校园露天音乐会都会吸引大批学生观众，使之成为校园 生活一道亮丽的风景线。(which)

Whether it rains or shines, the open-air campus concert every Thursday attracts a large number of student audiences, which has become a beautiful scene in campus life.

考查固定句型和定语从句。表示 “无论是……还是……” 句型为 “whether ... or ...”，引导让步状语从句；表示 “雨天” 用动词rain，表示 “晴天” 用动词shine，陈述事实用一般现在时；表示 “每周四的校园露天音乐会” 用the open-air campus concert every Thursday，作主语；表示 “吸引” 用动词attract，表经常习惯性动作用一般现在时；表示 “大批学生观众” 可用a large number of student audiences；后跟非限制性定语从句修饰上文，从句缺少主语，故用which；表示 “成为校园生活一道亮丽的风景线” 用become a beautiful scene in campus life，表示对现在的影响用现在完成时。故翻译为：“Whether it rains or shines, the open-air campus concert every Thursday attracts a large number of student audiences, which has become a beautiful scene in campus life.”。
