问题 A man escaped from the prison last night. It was a long time ______ the guards discovered what had happened.

选项 A、before
B、until
C、since
D、when

答案 A

解析考查It is...before的用法。犯人越狱发生在警卫发现之前，It is...before意为“(……之后，)才……”，符合题意，为正确答案，又如：It was several months before I was fit for the job．(几个月后我才适应了这工作。)until意为“直到……为止，直到……才”，一般不用于It is...until肯定句中，例如：They drank on until midnight(他们一直喝到半夜。)
