Harry is feeling uncomfortable. He _____ too much at the party last night. A．could drink B．should drink C．would have drunk D．must have drunk

Answer 1

D

试题分析：考查情态动词表示猜测的用法。句意：亨利看起来似乎不舒服。他肯定是昨晚的晚宴上喝多了。 根据时间状语last night可知，本句讲的是过去的事情，故先排除选项A，B。would have done是与过去事实相反的虚拟语气的主句结构，must have done表示对过去情况猜测，“肯定做过……”。由句意理解，这里是表示猜测。故选D。
