since 基本就倆解釋,用法如下：
（1） 是你所說的 自 ...以后,一般的確都配著完成時(shí)使用.
I have started working here since last year.=> 自去年起我就開始在這里工作了（而且仍持續(xù)中,所以用完成進(jìn)行時(shí)）
He has missed several classes since the beginning of the semester.=> 他從學(xué)期開始就缺了好幾堂課.
（2） 是“因?yàn)?、基?..緣故”的意思,你舉出兩個(gè)例句中的since 都是如此解釋.
譯文：
1.since very few people are actually concious of thee decision-making norms that their cultures have taught them,they never consider that those norms are far from universal.
因?yàn)楹苌偃苏嬲龝?huì)意識(shí)到他們做決定的標(biāo)準(zhǔn)深受個(gè)人文化背景影響,他們從不會(huì)考慮這些標(biāo)準(zhǔn)并非舉世通用的.
2.But since the other side feels the same way about their right way,the results of this teaching effort are usually profoundly non-educational.
但由于另外一邊也同樣認(rèn)為他們的方法是正確的,這種教學(xué)方式通常離真正的教育相去甚遠(yuǎn).
