They expected there____ more reviewing time before the final exams.
A、is
B、have been
C、being
D、to be
【正确答案】：D
【题目解析】：D他们指望期终考试前有更多复习时间。except后可以跟宾语从句或动词不定式。据本题分析，因为是“期望”的，所以还未发生。因此从句时态用将来时，根据时态一致原则，从句用过去将来时，可以说 The students expected (that) there would be more reviewing time before the final exams. 如果用不定式则可以说 The students expected there to be more reviewing time before the final exams.但不能用动名词，综合以上分析，只有D项是正确的。
