If there were no examinations, we should have ______ at school.

 If there were no examinations, we should have ______ at school.

A.the happiest time

B.a more happier time

C.much happiest time

D.a much happier time

答案及解析: D

解析:

由于是将有考试与没有考试作比较,所以应用比较级,不用最高级,由此排除A和C。选项B的错误在于用了more happier这样的双重比较级(即more后不能再加比较级)。
