Question

英语选择填空题。

Answer 1

你好;
( Were ) it to rain tomorrow , the opening ceremony ( would have ) to be postponed.

考点 : 虚拟语气

表示对将来的虚拟, 从句 : If + 主语 + were to + 其他 ( 如果省略 if 的话, 要用倒装, 即: Were
+主语 + to + 其他)

主句 : 主语 + would/ should /could + 动词原形

翻译: 要是明天下雨的话, 开幕式将不得不延期.

希望对您有帮助! 不懂的请追问!

Answer 2

句意“如果明天下雨，开幕式将被推迟”
前半句是倒装条件句，6个选项中只有were有此用法。
第一空填了were，说明句子用了虚拟语气，是对将来的虚拟，则主句用情态动词过去式，故第二空只能选would have.

Answer 3

Were it.....would have 表虚拟语气

希望对你有帮助哦~

Answer 4

were， will have 虚拟语气
