    选 B 参考; I did not find my wallet until I got to the station 。 到了车站我才发现我的钱包不见了 如果表示强调,将not until提前,主句倒装 Not until I got to the station did I find my wallet lost 。
     在肯定句中, till/until 意为“直到……为止”,主句的谓语动词须为延续性动词。 在否定句中, till / until 与否定词搭配,意为“直到……才”。
   如果把“ not … until ”变成“ not until …”置于句首时,主句要倒装。  例如:    Go straight on until / till you comes to the post office。
      I won”t go away until you promise to help me。    Not until he called me up did I know it。
        注意:若把 not until 引导的部分作为强调句型中的被强调部分,则主句中的主谓不倒装。例如:    It was not until he took off his dark glasses that I recognized him。
     = Not until he took 。

"It was ... that..."固定用法,强调,排除A,C "主语+not...until"所以排除D 综上所述,选B
