　　求教英语六级语法

　　“Theriseoftheunattractiveoversuccesseswasattributedmoretopersonalrelationshipsandlesstoabilitythanwasthatofattractiveovernightsuccesses.”这句话中,than后面为什么把谓语was倒装了?

　　不好意思,我打错一个词.原句应该是：

　　Theriseoftheunattractiveovernightsuccesseswasattributedmoretopersonalrelationshipsandlesstoabilitythanwasthatofattractiveovernightsuccesses.

　　我查了一下,than前后主语一致时确实可以省略,此句中than前后主语是不一致的.

　　than后面的主语应该是thatofattractiveovernightsuccesses

　　that指代的是therise.

　　现在已经查到,这是一个临时倒装句.
