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。)
