Question

You ________ in person; a telephone would have been enough.

A．couldn't have come B．needn't have come

C．shouldn't have come D．mustn't have come

 

Answer 1

B

【解析】B考察情态动词加完成式的用法。couldn't have come不可能已经做了某事； needn't have come 本不必做某事； shouldn't have come本不应该做某事； mustn't禁止，千万不要。句义：你本不必亲自过来，打个电话就可以了。故B正确。
