　　①热烈祝贺你们来到北大。你们将在 这里度过20世纪仅剩的最后几年。在这几年中，你们无疑将接受本世纪全部伟大的精神财富，以及这一世纪无边无际的民族忧患的洗礼。你们将以此为营养，充实并塑造自己，并以你们的聪明才智在这里迎接21世纪的第一线曙光。你们是名副其实的跨世纪的一代人。你们要珍惜这百年不遇的机会。

　　②发生在距今99年前的戊戌变法是失败了，但京师大学堂却奇迹般地被保留了下来，成为那次失败的变法仅存的成果。你们正是在这个流产的变法失败100年，也是京师大学堂成立100年的前夕来到这里的。当你们来到这到处都在建筑和整修的学校时，百年的沧桑，百年的奋斗，百年的期待，一下子也都拥到了你们的面前，我设想此时此刻的你们，一定是在巨大的欢欣之中感到了某种沉重。

　　③你们是未来世纪中国的建设者。你们将在未来的岁月中做出平凡的或是杰出的贡献，你们中有的人可能还会成为未来世纪非常出色的人物。但不论如何，今天，对于你们中的每一个人，都是决定自己一生命运的、不可替代的、非常重要的日子，那就是因为你们的名字和这所伟大的学校产生了联系。中国有12亿人，你们的同龄人也应该以千万为单位来计算，但只有极少数的人有幸能把自己的名字与这所学校联系起来。同学们，请以负重感来代替你们高考胜利的欢欣吧！

　　④你们从各地来到北大，从现在开始，你们已结束了中学学习的阶段，开始了大学学习的阶段，在人的一生中，这是非常重要的时刻。虽然都是学习，中学只是普通教育，大学则是专业教育，这才是真正打基础的阶段，你们将来为社会服务的许多本事，是在这个阶段学到的。

5．段④中作者说“这是非常重要的时刻”指的是什么？

It is not a secret that these are turbulent times that put everyone on edge all the time and it makes people angry with their families, co-workers, friends and relatives, frustrated (沮丧的)and highly annoyed just for the noise of the neighbors or the music coming from the opposite house. Anger and negative energy have a strong influence on everyone’s life, even when they don’t realize it.

Being in a calm state of mind is simply wonderful. Results of this can be seen when parents no longer shout at their children over any small thing and when one can keep him cool when bad things happen and doesn’t let the situation become worse by his negative influence.

Also results can be seen on a larger scale. In 1993 a very interesting scientific experiment called The US Transcendental Meditation experiment was conducted in Washington. A company called TM got 4,000 calm and relaxed people to simply sit and meditate (冥想) in a central Washington convention center. The results of this experiment showed that during those particular 8 weeks, violent crimes, such as murder, rape, assaults, clearly decreased by as much as 23%.

This is evident proof that meditation can change the state of mind, bring back peace of mind and collective meditation is contagious (蔓延的), just as anything done collectively is contagious. For example, a person has the urge to become aggressive (while in normal circumstances that person is very calm and normal), just because he is sitting at a stadium watching a football game and everyone around is shouting and is aggressive.

Isn’t increasing the quality of life worth spending 20 minutes of time on meditation? Yes, very few people follow through with a meditation method that should be a joy to do. Many start and leave it after only a few sessions.

So if collective meditation has proven that meditation works, that it calms people down and that it brings their levels of stress down, why not employ it in everyday life?
