must表推测不能用于否定句中吗？

语法书上说must表推测不能用于否定句中，那这道题是出错了吗？还是答案解析出错了原题是改错，划线must not receiveHer parents must not receive any message about her. They don't know what has happenedto her.A. must not have receivedB. ought not to receiveC. not ought to have receivedD. not ought to receiveA[译文]她的父母一定没有收到任何关于她的消息，他们不知道她出了什么事。[解析]选项分析。本题的考点为must have been表示猜测的用法，而ought to的意思是“应当，应该”'，其否定形式为ought not to,故排除选项C和D:画线部分用ought to不符题意，故排除，所以本题正确答案为A.
