英语中插入语的使用

But despite brave words - words are none braver，perhaps，than Spain's Prime Minister Mariano Rajoy hailing this as a "victory", -and the substantial sums involved the crisis will not be broken

插入语是一个句子, 成分有省略, 补全的话如下: words are none braver，perhaps，than Spain's Prime Minister Mariano Rajoy hailing this as a "victory",
去掉插入语和一些口语化的成分, 主句为: But despite brave words , the substantial sums involved the crisis will not be broken

主语是mary，因为is为系动词作谓语，they
say为插入语，插入语，就是去掉插入的成分句子仍完整。

But despite brave words and the substantial sums involved，这句话整个是作状语，整个句子的主语是 the crisis.
