问题 The city is expected______its energy use peak during the third quarter, but official figures have yet to be released.
选项 A、to see
B、to have seen
C、seeing
D、having seen
答案B
解析 时态题。expect sb．／sth．to do sth．是固定搭配，意为“预计某人／某物做某事”，本句是其被动形式be expected to do sth．，故排除C和D。如果动词不定式中的动作(see)发生在主句的谓语动词所表示的动作(expect)发生的时间以前，不定式要用完成式，因此B为答案。
