向您请教这题的答案并给讲一下，谢谢

it is commonly believed that it is_______ too much money has been invested in real
estate(房地产）_______has caused the crisis in Wall Street.
A that；that B that; which C what; that D because; that

Answer 1

A
我们可以把前面的it is commonly believed that 去掉只看后面这个强调句

it is_______ too much money has been invested in real
estate(房地产）_______has caused the crisis in Wall Street

因为强调句就是把IT IS和THAT去掉后这个句子还是成立的所以我们就看这个强调句的THAT应该放在哪里。

可以看出他句子的意思是想说是投太多钱在房地产这件事引起华尔街的危机
而且 too much money has been invested in real
estate这也是个完整的句子所以要把它变成主语就加个THAT变成主语从句
而第二个空也填的THAT是强调句的成分。

Answer 2

A.

这个句子从句较多。

it is commonly believed that……
it是形式主语，指代that引导的是主语从句。

it is that too much money has been invested in real
estate that has caused the crisis in Wall Street.

这是个it is…… that ……的强调句型。

that too much money has been invested in real
estate这个算是前面is的表语从句。
