hardly/scarcely … when 位于句首如何使用?并且可否在句子的其他位置使用?

hardly/scarcely … when 位于句首如何使用?并且可否在句子的其他位置使用?
例如had i hardly/scarcely got home wehen it began to rain.和i had hardly/scarcely got home wehen it began to rain.两个句子之间哪个正确?

“hardly…when(before)…”和“scarcely…when(before)…”这两个结构在含义上与as soon as及no sooner…than相近,都作“一……就……”解.hardly(scarcely)引出主句,when(before)引出从句,主句的动作与从句的动作一前一后紧接着发生.有人主张主句的谓语动词要用过去完成时,从句用一般过去时.
"hardly…When(before)…”和“Scarcely…when(before)…”这两个结构在含义上与as soon as及no Sooner…than相近,都作“一……就……”解.hardly(scarcely)引出主句,when(before)引出从句,主句的动作与从句的动作一前一后紧接着发生.有人主张主句的谓语动词要用过去完成
Hardly and scarcely both mean 'almost not' or 'only just'.For example,if you hardly had time to do something,you almost did not have time.Scarcely is more formal or literary.
Hardly和scarcely意思都是“几乎不”或者“刚刚”（表程度）.例如：you hardly had time to do something意味着你几乎没时间做某事.相比之下scarcely更正式、更书面.
• I hardly had time to ask her name.
我几乎没时间去问她叫什么名字
• We had scarcely arrived when he asked us to leave.
我们才刚刚到他就叫我们走了.
Hardly and scarcely can also be used with 'ever' to mean 'not often,almost never',with 'any' to mean 'very few,almost none'.
Hardly和scarcely也可以与ever连用,表示“很少,几乎从不”；与any连用,表示“很少,几乎没有”.
• I've got hardly any money left.
我几乎没剩一点钱.
• Hardly anyone agreed with her.
几乎没人同意她.
In speech,it is usual to say that you hardly ever do something,rather than that you rarely do it.
在演讲时,通常都说hardly ever do something,而不说rarely do something.
• I hardly ever go to the cinema.
我几乎从不去电影院.
再问： 那么hardly/scarcely had i got home when it began to rain.是否正确呢
