我非常有幸能够来到世界著名的医学学府—卡洛琳斯卡大学进修学习。一到这里，即被这里浓郁、严谨、平等的学术气氛所吸引、所感染。在这里，没有学术权威和小辈之分，在科学面前人人平等，都有发表自己见解和观点的权利与空间；有时为了一个小小的问题，学生会与大教授争论不休，毫无畏惧权威之意。我所在的科室每周二都有组会，这是一个大家相互学习交流的好机会。每周由一个研究者主讲自己最近的科研进展，然后，就是最热烈的时刻，大家毫无保留各抒己见、畅所欲言，对当天的主讲者提出各种各样的.问题和建议。我通过这样的学术交流，也收获颇多，不仅提高了自己的英文能力，而且也常常能捕捉到被我忽略的、而却非常有用的信息，使我在研究中茅塞顿开，更好地促进了下一步的研究工作。在这里，研究人员一般都比较敬业，比如我们实验室有位老太太实验员因为要进行动物实验，每天早上很早就到单位开始工作，如果实验没有结束，她也不会因干满八小时而下班，从她这里改变了我原来对欧洲人的印象，即比较懒散。
在瑞典工作学习的日子，接触了不少博士生，了解了瑞典培养研究生的制度。在瑞典对博士生的要求很高，除了修满40-80学分外，博士论文还必须包含至少4篇在国际期刊和主要国际会议上发表的文章；此外，博士生还必须承担20%的助教任务。博士生的文章被SCI等等录用，导师一般会资助他们参加几次国际会议。我想这是一个非常好的激励机制，更有利于培养高质量的研究生，也值得我们国内借鉴。

水——我们的朋友 平达曾说过：“自然界的一切事物中，唯有水最珍贵。”是啊，水是我们的朋友，没有了水，就没有了我们。让我们一起与水做个好朋友吧！ 水看见人们不节约用水，伤心地说：我对人类的所作所为感到不满，我为人类做了那么多的贡献，可人类总是滥用我。这样既会导致水源的\'流失，又会严重影响生态环境。 在生活中，处处都要用到水。洗菜要用水，洗车要用水，洗澡要用水??，这往往会浪费很多水。其实，请把水龙头开小一点，把废水再次利用，这样我们就能与水做好朋友了。比如：洗菜水可以浇花；洗澡水可以冲马桶??这样，不仅能节约用水，还对别的事物有好处呢！ 如果水能这
样一滴一滴的节约起来，虽然不是太多，但是全世界人民都这样做，怎么会没有水呢？ 人们可知道，世界上有许多地方水都很少，有些人，因为喝不上水，而去，他们说：“请他们喝酒，不如请他们喝水。”下雨天，曾是他们最快乐的日子，他们可以用雨水洗澡，还能接水，以后用。他们把水当做奇珍异宝， 每次喝水都要去很远的井里去挑，那井里的水比黄河水还浑浊，比海水还难喝。由此可见，他们是多么爱水啊！如果我们能节约用水，他们的生
活难道会这样吗？ 不节约用水，不但会导致水源的流失，还会影响生态环境。 有些工厂既不节约用水，还排放污水放到河流中，这样，水不仅流失了，还会影响生态环境。
