Art museums do not usually
think of their collections as capital or consider the interest income that
would be generated if a portion of the capital would have been invested
in another form.

(A) be generated
if a portion of the capital would have been

(B) have been generated
if a portion of the capital would have been
     

(C) be generated
if a portion of the capital were

(D) be generated
if a portion of the capital was（C）
     

(E) be generated
if a portion of the capital had been

答案是C

我选择的是E：本题考察虚拟没有问题，选C的话就是按照一般的虚拟判断的。我选E是因为觉得这是一个复合虚拟：首先要先先把钱投资了，然后才有收益。所以我觉得时间上有明显先后，投资是发生在generate前的过去的事情。。。

是想太多了吗？盼解释~
