【文章难句】

And thanks to the continual miniaturization of electronics and micro-mechanics, there are already robot systems that can perform some kinds of brain and bone surgery with submillimeter accuracy - far greater precision than highly skilled physicians can achieve with their hands alone.

【词汇突破】

miniaturization

n. 小型化  ，微型化

submillimeter

n. 亚毫米  

【结构分析】

       本句的主干是 there are already robot systems，句首介词短语 thanks to 引导原因状语，that can perform some ... with submillimeter accuracy 是修饰句子主干中 systems 的定语从句，破折号后面 far greater precision 做 submillimeter accuracy 的同位语，其后面 than highly skilled physicians can achieve with their hands alone 是一个比较状语从句。
