In one sense a metaphor for the times it helped create, in another sense the telephone is their polar opposite.
老师这里in one sense a metaphor for the times it helped create是部分倒装吗?部分倒装不应该是提前助动词吗,为什么这里提前了名词?倒装还有哪些种类?
这是一种前置强调fronting,前置不一定触发倒装,要看什么成分前置。宾语/表语的前置强调是比较常见现象:
e.g. I bought a new camera. And a very expensive camera it was.
