介绍： The potential evolution of today's technology, and its social consequences,is dazzlingly complicated,and it's perhaps best left to science fiction writers and futurologists to explore the many possibilities we can envisage.
译文：当今技术的发展趋势及其社会影响是极为复杂的，也许，最好的办法是将我们所能设想到的种种可能交给科幻小说家和未来学家去探索。
分析：本句是由and连接的两个并列句。第一个并列句的主语为The potential evolution…and its social consequences。第二个并列句的主干是it's…best left…。由于第二个并列句的真正主语很长，故采用了it做形式主语，真正主语是to explore the many possibilities…，真正主语中还包含了一个定语从句修饰possibilities;谓语动词is left是被动语态，best是副词，修饰该谓语动词;介宾短语to science fiction writers and futurologists是left的状语，说明left的对象。
