C. was there   D. there should be

Answer

B

【解析】

试题分析：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。

【名师点睛】

虚拟语气用于条件状语从句中的用法：

1.表示与现在事实相反的假设，条件状语从句中的谓语动词用过去时（be动词一律用were），主句中的谓语动词用“would/should/could/might +do”。如：

If I were a boy, I would join the army.

2. 表示与过去事实相反的假设，条件状语从句中的谓语动词用过去完成时，主句中的谓语动词用“would/should/could/might +have done”。

If I had worked hard before, I would not have been a poor man now.

3.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should(were to)+ do，而主句中的谓语动词用“would/should/could/might+ do”。如：

If it were to rain tomorrow, the football match would be put off.

若句中含有should/were/had，可以引起倒装。

考点：考查虚拟语气。
