(2010年福建毕业班检查)I am delighted________as chairman of the Students’ Union last winter.
A．to appoint B．to be appointed
C．to have appointed D．to have been appointed
解析：选D。考查非谓语动词。sb.be delighted后常接不定式，同时根据句意表示“我很高兴去年冬天被任命为学生会主席”，appoint这个动作发生在“过去，且已经完成”，用不定式的完成时态，而且I和appoint之间为动宾关系，所以用to have been appointed，答案选D项。
