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。
