为什么用since不用from请各位高手多多指点.thanks.

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.

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

原句有问题。也许就应该有since或者from...on

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

how long have you____? how long have you been 用法 How long have you been skating? How long have you been collecting shells？与How long have you collected shells?的区别 how long have you been here 和 how long have you stayed here 的区别 how long have you been keeping this to yourself? How long have you been married? 你们结婚多久了？ how long have Liji and Guoda been married? How long have you been like this?是什么意思？ How long have we been run?错在哪里
