拜读了曹老师than what...文章后遇到的一个疑惑

曹老师，您好，我读了您的 [比较分句than what中what保留还是删去] 文章后，今天读外刊遇到一个句子，It argues that the bet against subprime mortgages was far riskier than is often appreciated.

这里的比较项应为形容词比较级riskier，但than分句中缺少的主语并不是比较对应项riskier吧。所以这里是不是应该为than what is often，这是外国编辑写错了吗?

It argues that the bet against subprime mortgages was far riskier than is often appreciated.

如果把than理解为连词在从句中不作成分，than分句保留谓语动词而省略主语只能是下面二种情况之一：

1 省略的主语为比较对应项；

2 省略的主语为嵌入分句（即形式主语it和外置的that从句或不定式分句）。

本句中than分句省略的主语就是嵌入分句，把补全省略后为：

It argues that the bet against subprime mortgages was far riskier than it is often appreciated that it would be.

Appreciate在此意为realize。That从句的主语it指代the bet against subprime mortgages。That从句的表语为比较对应项，必须省略。

所以这个句子是正确的句子。Than后面不可加what. 加what被认为是uneducated。
