—I think the man over there must be Bob.
-- It be him. He has to Australia.
A. can’t, gone
B. can’t, been
C. may not, been
D. mustn’t, gone

(答案→)A. can’t, goneB. can’t, beenC. may not, beenD. mustn’t, gone解析： 本题的含义是那个人不可能是鲍勃，他已经去了澳大利亚。去了某地不在此处通常用have或has gone to+地点，故不选BC,鲍勃不在此处，那么那个人是鲍勃的可能性是最小，与句意较符合的应该是can’t，故选A。
