同学好,
这是部分倒装.
完全倒装：完全倒装即把整个谓语放到主语之前（是整个谓语动词，而非助动词）。
部分倒装：部分倒装即只把谓语的一部分（如助动词、情态动词等）放到主语前，或把句子的强调成分提前。

这里Not only提前后，要将助动词（这里是情态动词）也提前。

请看下面四个例句：not only放在句首，后接句子时要用倒装结构：
(1) Not only should proletarians emancipate themselves but also the whole mankind. 无产者不仅要解放他们自己，而且要解放全人类。
(2) Not only does television appeal to those who can read but to those who can't. 电视不仅吸引阅读的人，而且也吸引了不会阅读的人。
(3) Not only was everything Albert Einstain had taken away but also his citizenship was deprived of. 爱因斯坦的财产不仅被掳掠一空，而且他的德国国籍也被剥夺了。
(4) Not only had the poor man been fined,but also he had been sent to prison. 这个可怜的人不仅被罚款，而且还被送进了监狱。
