没有错。be solved前面省略一个should。句型：It's urgent that sb (should) do sth\sth (should )be done。真正主语是that the acute problem of air pollution in the city be solved。it是形式主语。

这是一个主语从句，主句谓语是“is”；后面的从句的谓语是“be”。

因为这是一个同位语从句，句子真正的谓语是is， be solved是从句里面的谓语

that后面的从句就是it的同位语，为了避免头重脚轻，用it代替，并且把真正的主语放在最后

没错。句型It is urgent that ....,
that后从句用虚拟语气，从句谓语动词用should+V 或用V ，这里是被动，所以用be solved.类似的有：It is necessary that he be sent to New York .
The doctor's suggestion is that the patient be operated on immediately.
