问题 She oughtn’t to have stood in a queue: she______her train ticket from the Automatic Ticket Machine.
选项 A、could have got
B、must have got
C、has got
D、got
答案A
解析 情态动词题。本题考查的是情态动词完成式的用法。前半句使用了oughtn’t to have done的结构，表示“过去本不应该做某事(实际上却做了)”；后半句则说明原因，could have done表示“过去本可以做某事(实际上却没做)”，所以选项[A]为答案。[B]表示“过去肯定做过某事”，而选项[C]和[D]都是陈述语气，表示做过了某事，均与句意不符，故排除。
