"快怎么"用英语怎么说.比如说"快到你家我会给你去电话"怎么说?

almost

I'll call you when I almost reach your house.
I'll call you when I am almost there.

I will call you when I arrive your home

不用那么按原意的，主要还是口语上的，能让别人听懂最重要

I will call you when I will reach your home.

i will call as soon as i arrive your home
不是所有语言都像汉语这么博大精深
意思一样就可以
这个是一怎么就怎么的意思
as soon as
