whether的倒装句

没有倒装句，例如：

1、Whether we need more food depends on how many people turn up.我们是否需要更多的食物，这要视到场人数而定。

2、I asked whether they could change my ticket.我问他们是否可以给我换票。

3、I'm not sure whether I should tell you this.我拿不准该不该把这事告诉你。

whether用于引导让步状语从句时意为“无论”，若省略whether需倒装，将谓语置于句前，用原形

"Whether he is rich or poor，I'll marry him"

"Be he rich or poor，i will marry him”
