A. Maryandhersonmustbehomebynow.
B. Carelessreadingmustgivepoorresults.
(答案→)C. It’sgettinglate,andImustleavenow.
D. Hemustbeworkinglateattheoffice.
解析：考查虚拟语气：must可以表示“必须”是指事实，C项的意思是：很晚了，我必须走了。而如果表示推测，这是肯定的推测，不一定是事实，A. Mary and her son must be home by now. 玛丽和她儿子现在一定在家。B.Careless reading must give poor results. 粗心阅读一定会有很差的结果。D. He must be working late at the office.他一定在办公室工作的很晚。选C。
