例192　To be sure, he performs an impressive variety of interesting compositions, but it is not necessary for me to visit Avery Fisher Hall, or anywhere else, to hear interesting orchestral music.

【结构分析】句子开头是个不定式短语To be sure, but前面的句子主干是he performs an impressive variety of interesting compositions, but后面是个it无主句，真正的主语是to visit Avery Fisher Hall, or anywhere else, to hear interesting orchestral music, it只是形式主语。

【亮点回放】此句话的亮点在于it形式主语这种句型的使用，比如it is not necessary for me to take part in the party with fantastic clothes。

【核心词汇】

to be sure　我能确定的是

an impressive variety of interesting compositions　很多有趣的演出

hear interesting orchestral music　听一场有趣的交响乐演

【参考译文】我能确定的是，他能表现出很多有趣的乐章，但是我却应该不会去Avery Fisher Hall或者其他地方去听一场有趣的交响乐演出。
