题目内容

This painting is so valuable that it is rather difficult to calculate _______ its price would be if the museum _______ to sell it.
A.how much; would wantB.what; wanted
C.what; wantsD.how much; wants
B
考查宾语从句和虚拟语气。句意“这幅画是如此的贵重,以至于计算它的价格是相当的困难,如果那家博物馆想把它卖掉的话。”calculate后的宾语从句缺少表语,用what,排除A、D;if引导虚拟语气,与现在相反,用一般过去时。故选B。
