I have met so many friends in my college life. They have exerted enormous influence on my life. However, one of my most impressive friends is my roommate, Li Ming.

　　In the class meeting on the first day of school, Li Ming did not impress us at all. We started to notice him because he was always late for classes. We were thus impressed by his laziness. I came to know him and his situation because we were roommates and spent much time together: his mother was seriously ill and sick abed in long-term, his father left him and his mother mercilessly. Hence, it was him that shouldered the heavy burden of taking care of his sick mother supporting the whole family. Finally, under great pressures, he balanced his life and study perfectly: he was no longer always late, took good care of his mother and even won the scholarship many years in a row.

　　The experience of Li Ming can be one of the most convincing cases of the power of persistence and will. He left a deep impression and imposed a durable influence on me. Indeed, friend such as him can be regarded as asset and property in our life. We have rights to choose our own friends，but we should also be prudent and sensible enough to choose friends who can bring us “positive energy”. (228 words)

　　在我的大学生活中，遇到了很多朋友。他们对我的人生产生了重大的影响。然而，我印象最深的朋友是我的室友李明。

　　在开学第一天的入学班会上，他没有给全班同学留下任何印象。李明让我们开始认识他，是因为他总是上课迟到，同学们都以为是个懒惰的人。因为我们是室友，平时的交往比较多，后来我才慢慢了解到他的情况：原来他的母亲罹患重病，长期卧床，父亲残忍地离开他们而去，照顾生病的母亲和养家重任只能由他来承担了。令人惊讶的是，在重压之下，他将自己的生活和学业平衡地很好：他不再总是迟到，将妈妈照顾的很好并且连续几年获得奖学金。

　　李明的经历是坚持和意志的作用的最有说服力的例子之一。他给我留下的印象无法磨灭，他对我造成的影响持续深远。的确，这样的朋友被视为我们生活中的财富和资产。我们有权利选择自己的朋友，然而交友的过程中，我都应该足够理智和谨慎，选择那些能够给我们带来正能量的真正的朋友。
