一、表示时间含意不同
1、from只表示某事的起点，要表示起止需用from...to〔until〕...结构。
例：Great changes have taken place in Beijing from 1990 to 2000.
从1990年到2000年，北京发生了巨大的变化
2、since是指延续到说话时刻的动作或情况开始于何时,是站在动作中止的时间点往过去追溯计算。
例：Great changes have taken place in Beijing since 1990.
自1990 年以来北京发生了很大的变化。
二、时态用法不一样
1、有from表示时间起点的句子，现在、过去、将来的时态都可使用。
2、since表示时间起点的句子不用将来时态。
三、词义广泛性不一样
1、from
英 [frəm] 美 [frəm]
prep.(表示起始点)从…起，始于；(表示开始的时间)从…开始
2、since
英 [sɪns] 美 [sɪns]
conj. 因为；由于；既然；自…以来；自…以后
prep. 自…以来；自…以后
adv. 后来
from 用在已完成的形式，通常 要加 上 to
from 1990 to 2000 ...
since 用在还在发生
给你例子
Mr. A was the president from 1900 to 2000
Mr. A is the president since 1900
from可以用于多种时态,比如现在,过去;
since用于完成时
