---I’m thinking of losing weight these days.
----Oh, you ______ be out of mind. You’re 50 kilograms at the most!
A.mustB.willC.willD.may
A

试题分析:句意:我这段日子一直在想减肥。噢,你一定是疯了。你现在最多也就100斤。must表肯定推测。
点评:must有“必须”“肯定”“偏要”的意思,对must的肯定推测时高考必考的语法点,对现在情况的肯定推测用must + do;对过去情况的肯定推测用must have done.must还可表示责备,抱怨的语气,意为“偏要,硬要”。
