Question

After inspecting the building, specialists discovered some faults that otherwise ___________.  

A．were overlooked	B．would be overlooked
C．had been overlooked	D．would have been overlooked

Answer 1

D

考查虚拟语气。此题是由otherwise引导的含蓄条件句的虚拟语气，表示的是过去，所以主句形式为： would/could/might + have done ，句意：在检查完这个建筑物之后，专家们发现了一些缺点，否则的话这些缺点就会被忽视。所以选D。
