答案选B.
先看下题目意思,对话：
A说：在北京的时候我没有去看我们以前的老师.
B说：但是我认为其实你应该去的.
should表示应该做某事,至于做没做无从得知,因为设定在将来.
should have 是正确答案,should have done sth.意思是“本应该做某事,但是没有做”.
outght to 也是应该做某事,设定在将来
must have done sth."肯定做了某事",是一种对过去的推测

你是不是想选A啊 呵呵 这道题是考察虚拟语气 should have done 表示应该做而没做 这里选B 整体为 but I think you should have seen your teacher 表示我以为你去了（结果没去）

第一句说的是，我在北京时没有去看我以前的老师，

But you should have 这是虚拟语气，意思是：你真应该去（看你的老师）。

第一句是过去式。所以回答过去做的事儿，的要用过去时，在过去没有做过而希望做就用过去完成时啊。

should have 表示对过去的虚拟，意思是应该做而实际上并没有做某件事
should 意思是将来应该做某件事
