问题
选择题
The principal walked onto the platform and seated himself in a chair, _______ for answering questions.
A．prepared
B．being prepared
C．prepared
D．preparing
答案
答案：C
题目分析：考查非谓语动词。sb be prepared for sth/ to do sth准备做某事，相当于be ready to do sth。句意：校长走上讲台坐在一张椅子上，准备回答问题。prepared是形容词化的过去分词，本句相当于who was prepared for...。故选C。
