她屏蔽了所有即将要发进来的信息.
She muted all incoming messages.
She blocked all incoming messages.
She obstructed all incoming messages.
She prevented any messages from coming in.
你的那两句翻译都是对的、不过时态是现在完成时,
一般直接用一般过去时态更确切,不过得看上下文、
She has blocked all the incoming messages.
She has blocked all the messages from coming in.
没有语法错误,就 incoming 拼写错了.
