Ants are pretty small. You might think that they _________be rather weak. But what you might not know is that ants are actually very strong for their size.

A. need                        B. can't                       C. must

【回答】

C

【解析】句意：蚂蚁很小，你可能认为它们一定很软弱，但你可能不知道的是，蚂蚁的体型其实非常强壮。need意思是需要；can’t表示否定推测；must表示肯定推测；根据句意，表示“他们肯定很虚弱”，所以是肯定推测，故选C。
