---It is said that China has been a member of WTO since December 11, 2001.
---Well, it’s wonderful that the Chinese people ______ have made so much progress these years.
A．must
B．can
C．should
D．may
答案
A。
考查虚拟语气。句意：据说中国自从2001年十二月十一日以来就成为世贸组织的成员。——嗯，太棒了。中国这些年来肯定取得了巨大的进步。表示对过去事情的肯定推测用“must+have+done”，译成“一定做过某事”，该结构只用于肯定句。故选A。原答案有误。
