It will not be long before the inflation figure starts to fall中的before如何翻译。

It will not be long before the inflation figure starts to fall...
过不了多久，通货膨胀率就会开始下降。
没有before，这个也能翻译出来，但有了的话怎么理解这个词在句中的意思。

Answer 1

朋友你好，这里的before应该是祈祷一个关联引导的作用。去掉before不行，但是可以将这里的before置换成that。
It will not be long that the inflation figure starts to fall...
希望对你有帮助，呵呵。

Answer 2

personally, think when is better for your context.
it won't be long when the inflation would start to fall.
