问题描述:

-how long have been like this? -octerber 13th, monday.
为什么用since不用from请各位高手多多指点.thanks.

since [简明英汉词典]
[sins]
adv.以后, 后来, 以前
prep.自从, 自...以来
conj.自...以后, 自...以来, 因为, 既然
from [简明英汉词典]
[frCm, frEm, frm]
prep.从, 今后, 来自, 由于

从语法角度上来讲since from都接时间点
但是from通常都是与to搭配
从……到…… 表示一段时间
而since不用与什么搭配 单独运用即可
从……开始一直到现在 表示这一段时间

老实说我觉得这句对话有语病~~问句没主语,而答句又答非所问,除非是
-how long have you been like this?
-since october 13th,monday.

原句有问题。也许就应该有since或者from...on
