---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

試題分析：句意：我這段日子一直在想減肥。噢，你一定是瘋了。你現(xiàn)在最多也就100斤。must表肯定推測。
點評：must有“必須”“肯定”“偏要”的意思，對must的肯定推測時高考必考的語法點，對現(xiàn)在情況的肯定推測用must + do；對過去情況的肯定推測用must have done.must還可表示責備，抱怨的語氣，意為“偏要，硬要”。
