题目内容
.--- Where is your father?
--- I'm not sure. He_______ in the office.
A. must be B. maybe C. may be D. perhaps
【答案】
C
【解析】
试题分析：句意：---你父亲在哪里？---我不确定。他可能在办公室。must be一定是，表示对现在事实的推测；maybe副词，可能，大概，也许；may be可能是，表示对现在的可能性推测；perhaps副词，可能，大概，也许。因为空后无任何系动词或实义动词，故需填情态动词+be结构，有因为题干中有I'm not sure表示不确定的成分，故选C。
考点：考查情态动词。
