5 插入语和破折号

he created an entire science of communication which has since inveigled its way into a host of applications, from DVDs to satellite communications to bar codes - any area, in short, where data has to be conveyed rapidly yet accurately.

 问题:本句的阴影部分的语法结构是什么?

①“from DVDs to satellite communications to bar codes是插入语吗?

破折号起到什么作用?破折号后面的语法结构是什么?是一个完整的句子吗?

from DVDs to satellite communications to bar codes”不是插入语,只是这里有个逗号,是结构足够清晰,你把逗号去掉也不影响。破折号可以看做补充说明作用,可以看成状语,实质就是in any area.如果把破折号去掉也可以,不过要加in,不然不完整。
