beneath(介词,在……之下) the streets of modern cities exists(谓语) the network of cable required(过去式做状语,带着后面的部分修饰the network of cable) to satisfy needs of inhabitants
所以,正常语序是the network of cable required to satisfy needs of inhabitants exists beneath the streets of modern cities 。 exist确实是不及物动词 ,它后面再正常语序下跟了介词beneath
追问为什么会出现这种倒装呢?
