来美国求学的中国学生与其他亚裔学生一样，大多非常刻苦勤奋，周末也往往会抽出一天甚至两天的时间去实验室加班，因而比起美国学生来，成果出得较多。我的导师是亚裔人，嗜烟好酒，脾气暴躁。但他十分欣赏亚裔学生勤奋与扎实的基础知识，也特别了解亚裔学生的心理。
因此，在他实验室所招的学生中，除有一名来自德国外，其余五位均是亚裔学生。他干脆在实验室的门上贴一醒目招牌：“本室助研必须每周工作七天，早10时至晚12时，工作时间必须全力以赴。”这位导师的严格及苛刻是全校有名的，在我所呆的3年半中，共有14位学生被招进他的实验室，最后博士毕业的只剩下5人。1990年夏天，我不顾别人劝阻，硬着头皮接受了导师的资助，从此开始了艰难的求学旅程.

    Most students came from China worked hard as well as other Asian students who usually spent one to tow days to study even in weekend. Therefore, they got more achivements  than American students. My master was an Asian Amrican who was badtempered,liked smoking and drinking. But he completely appriciated in Asian students' diligance and outstanding basic knowledge, moreover, he also undersood Asian students' pshchology.

    Therefore, in his lab except one of Germen origin,the rest five were all Asian origin. He took a markable signboard on his lab door:"Asistants work 7 days per week and from 10:00 to 24:00. You have to do your best in working time." This tutor was famous on his strictness and rigor in the school. In my half and three years in this school, there were 14 students entered into his lab,but finally only five people got the degree of doctor. In the summer 1990, I accepted his aid regardlessly other people's dissuasions, and my difficult journey of studying was begining.

        我不太相信记忆,那不可靠,我总是会将惆怅美化成梦.然而除了记忆,什么也没留下.

        雪地上的脚印会在春天走远,沙滩上的足迹会被海浪带走.我执意要保留你的微笑,无非只是希望在失落的瞬间想起,但这却也成了奢望.

        我不太相信记忆,那不可靠,因为时间会让美好变成模糊,然而除了记忆.什么也没留下.

        眼角的皱纹会沿着岁月爬行,风中的云会因为悲伤变成海洋,我执意要保留你的微笑,无非只是希望在寂寞的瞬间想起,但这却也成了奢望.

        你是否真的来过,我沿着时间线,摸索着趟过一条条割断记忆的河流.我背过身,顺着来时路倒退,不知要走多久.

        其实,我知道即使这样,人生也在前行,我没有回头看来时的路,于是眼前的景物渐行渐远,你是否真的来过?
