Really embarrassing
A do you D does it 为什么选D不选A，为什么主语是to be mistaken for someone ，选A怎么就不行了呢？？
---How ___ feel to be mistaken for someone else?
---Really embarrassing.
A. do you B. does that C. did you D. does it
D。考查固配巧定句型。句意：--被误认为是别人感梁卖肢觉如何啊?--真是令人尴尬的。橡世It feels + adj. + to do sth中不定式是真正的主语，只有it可作形式主语。
反义疑问句困郑啊，分析How does it feel to be mistaken for someone else，这个句子的的形式主语是it真正的主语是o be mistaken for someone,所汪唯颂以是does it？，希望有帮助山枣
