whether可以用于句首做状语吗？

Question

如题所述

Answer 1

it remains to be seen whether和it remains to be that的区别及运用是：
1、it remains to be seen whether 这还有待观察，指不确定的事
it remains to be that 它仍然是，尚待成为...
2、it remains to be that 表陈述，多用于陈述句中。
it remains to be seen whether表是否。
例如：
However, it remains to be seen whether the process can be scaled up.
然而，加工能否成比例增加还要拭目以待。

It remains to be seen how weather conditions affect the air flows that makeformation flight more efficient.

现在仍需考虑天气情况对气流的影响，这会关系到编队飞行的效率。
