the students expected there _____more reviewing classed before the final exams.A.is B.to beC.being D.have been

B，因为句子里已经有一个谓语动词了，所以后面的there be结构中的be动词（表示“存在，有”）要用非谓语形式，我们可以把there看作是一个形式上的宾语。expect这个动词后面，碰到另外一个动词，一定要用动词不定式形式，所以这道题目选择B。这种结构也可以叫做“there be结构的非谓语形式”。动词expect之后接不定式作宾语补足语，当然也可以接宾语从句。本句既可以说The students expected there to be more reviewing classes before the final exam．，也可以说The students expected there would be more reviewing classes before the final exam．句子译文：“学生们希望在期末考试前有更多的复习课。”
解释语法什么的都是浮云，培养语感才是王道，得多听多看多说多写！
