问题 There being no cause for alarm, you______in such a panic yesterday.

选项 A、need not act
B、did not need to act
C、need not have acted
D、did not need to have acted

答案 C

解析本句是虚拟语气的句子。前半句没有给标准的虚拟语气句式，没有用连接词if引导的非真实条件句，而是给了一个分词独立结构，但是起的作用与连接词if引导的非真实条件句是一样的。句子中提供了过去的时间状语yesterday，所以用need not have acted。
