C. that
D. How
解析：考查强调句。句意：直到晚上很晚了，他的丈夫才到家。1.当Not until位于句首时,句子要倒装。其结构为:Not until+从句/表时间的词+助动词+(主句)主语+谓语+...。如: Not until the teacher came in did the students stop talking.直到老师进来学生们才停止讲话。 2. not until的强调结构为:It is / was not until+从句/表时间的词+that+...。上面两句改为强调句为: It was not until the teacher came in that the students stopped talking.It is not until next week that the sports meet will be held.，故选C项。
考点 :考查强调句
