题干：4.[单选题]句子The decision of the New York Philharmonic to hire Alan Gilbert as its next music director has been the talk of the classical-music world ever since the sudden announcement of his appointment in 2009.属于哪种简单句________

选项：A. 主语+谓语

B. 主语+谓语+宾语

C. 主语+谓语+宾补

D. 主语+系动词+表语

题号：4.【答案】D。解析： of the New York Philharmonic to hire Alan Gilbert as its next music director是The decision的定语，of the classical-music world是the talk的定语，ever since the sudden announcement of his appointment in 2009是句子的时间状语，在找句子主干时，这些修饰成分都可以先忽略不看。因此，本句的主干为The decision has been the talk，故本句是“主语+系动词+表语”结构。故本题正确答案为D。
