高中英语选择whose fault do you think it is

网友回答

选that这个是主语从句.‘do you think是插入语,先抽出来不管.
whose fault it is ____ we are losing all the money?
变形：it is whose fault (that) we are losing all the money.
it是主语,指代 we are losing all the money
======以下答案可供参考======
供参考答案1:
我觉得是that吧，相当于it is whose fault that we ...,主语从句，it做形式主语，that引导的从句是真正主语。
供参考答案2:
选that。
 
后面的从句不缺主语，谓语，宾语。作whose fault 的同位语。
what 和 which 一般作主语和宾语。
when作时间状语。
