It was announced that only when the fire was under control would the residents be permitted to return to their homes.

请帮忙分析一下成分和句式,是不是存在着强调倒装?
可以的话希望改成一个普通陈述句子.
谢谢!

That the residents would be permitted to return to their homes only when the fire was under control was announced.
这个句子总体是个强调句，强调成分为句子主语，即only when the fire was under control would the residents be permitted to return to their homes.而主语中又有only提前的倒装

主语从句的条件倒装句
