【题目】The celebration is to begin at 9:00 a.m., but we would put off our plan, ________ a sudden storm.

A. there was B. should there be

C. was there D. there should be

【答案】B

【解析】考查虚拟语气和倒装。句意:庆典上午九点开始,但是我们会推迟我们的计划,如果突然下暴雨的话。表示与将来事实相反的假设,条件状语从句中的谓语动词用一般过去时,或用should(were to)+ do,主句中的谓语动词用“would/should/could/might +do”,在省略if的时候,要使用部分倒装的形式,should可以提到句子前面。故选B。
