Question

请求各位大神讲解答案，及选择该答案的原因

You ______, for the concert has been canceled due to the sudden illness of the first violinist.
A. didn’t need to come
B. needn’t have come
C. need not to come
D. do not need come

Answer 1

因为音乐会被取消了用的是has been,也就是现在完成时答纯，所以排除A过去式！
B，You needn't have come ,这的意思就是你已经去了，禅举而原句的意思清袭咐是你现在不需要去，排除B；
D,语法错误，应该是do not need to come
So, the answer is C.

Answer 2

这个题选B
