—“Crash diets” make us lose weight fast and I am all into that.

—But it_______better to work out.    

A.had

B.would be

C.wouldn’t have been

D.must have been

答案

答案:B

题目分析:本题考察情态动词用法,“情态动词+have done”表示对过去情况的虚拟或者推测;wouldn’t have done本不会坐某事,实际上却做了;must have done一定做了某事;根据句意可知本题是对现在情况的推测。句意:—Crash diets 让我很快就减肥了,我很喜欢它。—但是锻炼会更好。本句使用would对现在情况进行的说明。故B正确。
