only 引导的部分倒装Only when the war was over was he able to return home.这句是部分倒装吧?那为什么要把was 倒装了?后面的句子 可以还原成 he is able to return home.那这个句子里谓语在哪里?是be able to return么

only 引导的部分倒装
Only when the war was over was he able to return home.这句是部分倒装吧?那为什么要把was 倒装了?后面的句子 可以还原成 he is able to return home.那这个句子里谓语在哪里?是be able to return么
答
需要倒装的是主句部分，也就是 he was able to return home,谓语是was，把was 提前，when引导的只是个状语从句，跟倒装没关系。
答
be able to return home是谓语
be+表语 叫谓语
答
He was able to return home only when the war was over .
放后面就不倒装,倒装的是主句,动词提前,这里谓语动词是was.
