请帮我分析下这个句子的成份,还有stands怎么会跑前面?

这是倒装句.
正着说就是the monument to People’s Heroes stnads at the center of the square.这样就很明了.monument to poeple's heroes,纪念人民英雄的碑牌,stands,处在,center of the squre,广场的中央.
于是现在把at the center of the square这个地方用there来替代,变成the monument to People’s Heroes stnads there.
把句子倒过来,变成There stands the Monument to the monument to People’s Heroes.意思不变.
然后指明there是哪里,There stands ‘at the center of the square’ the Monument to the
People’s Heroes.
就完成啦!
简单的来想的话,举例说there are two pens.正着说实际上是Two pens are there.但是倒过来更顺口.同样There are on the desk two pens 和Two pens are there on the desk.也是一样的,只不过指明了there所指的地点.

"There be + 宾语“的句型应该很熟悉吧？这个句子就是类似的结构... there stands the monument.
分析句子的时间，最重要的是要把修饰成分拨开，只看主谓宾就好了。
at the center of the square 用来修饰 stands; to the Pople's heroes 用来修饰 monument.
