    中国哲学同外国哲学不同之处极多，其中最主要的差别之一就是，中国哲学喜欢谈论知行问题。我想按照知和行两个范畴，把中国文化分为两部分：一部分是认识、理解、欣赏等等，这属于知的范畴；一部分是纲纪伦常、社会道德等等，这属于行的范畴。这两部分合起来，形成了中国文化。在这两部分的后面存在着一个最为本质、最具有特征的深义的中华文化。

    陈寅恪先生论中国思想史时指出：“南北朝时，即有儒释道三教之目。故自晋至今，言中国之思想，可以儒释道三教代表之。此虽通俗之谈，然稽之旧史之事实，验以今世之人情，则三教之说，要为不易之论。……故两千年来华夏民族所受儒家学说之影响，最深最巨者，实在制度法律公私生活之方面，而关于学说思想之方面，或转有不如佛道二教者。”

    事实正是这个样子。对中国思想史仔细分析，衡之以我上面所说的中国文化二分说，则不难发现，在行的方面产生影响的主要是儒家，而在知的方面起决定作用的则是佛道二家。潜存于这二者背后那一个最具中国特色的深义文化是三纲六纪等伦理道德方面的东西。

    专就佛教而言，它的学说与实践也有知行两个方面。原始佛教最根本的教义，如无常、无我以及十二因缘等等，都属于知的方面。八正道、四圣谛等，则介于知行之间，其中既有知的因素，也有行的成分。与知密切联系的行，比如修行、膜拜，以及涅槃、跳出轮回，则完全没有伦理的色彩。传到中国以后，它那种无父无君的主张，与中国的三纲六纪等等，完全是对立的东西。在与中国文化的剧烈冲击中，佛教如果不能适应现实情况，必然不能在中国立定脚跟，于是佛教只能做出某一些伪装，以求得生存。早期佛典中有些地方特别强调“孝”字，就是歪曲原文含义以适应中国具有浓厚纲纪色彩文化的要求。由此也可见中国深义文化力量之大、之不可抗御了。

    这一点，中国不少学者是感觉到了的。比如，梁漱溟先生说，“中国人把文化的重点放在人伦关系上，解决人与人之间怎样相处”；冯友兰先生说，“基督教文化注重的是天，讲的是‘天学’；……中国的文化讲的是‘人学’，注重的是人”。这些意见都是非常正确的。

    国外一些眼光敏锐的思想家也早已看到这一点，比如德国最伟大的诗人歌德就说：“中国人在思想、行为和情感方面几乎和我们一样，使我们很快就感到他们是我们的同类人，只是在他们那里一切都比我们这里更明朗，更纯洁，也更合乎道德。还有许多典故都涉及道德和礼仪。”正是这种在一切方面保持严格的节制，使得中国维持到几千年之久，而且还会长存下去。

    中国文化同世界其他国家的文化，既然同为文化，必然有其共性。我想强调的却是它的特性。中国文化的特性最明显地表现就是它的伦理色彩，它所张扬的三纲六纪，以及解决人与人之间的关系的精神。

关于机械波的概念，下列说法正确的是（    ）

    When asked about happiness, we usually think of something extraordinary, an absolute delight, which seems to get rarer as we get older.

    For kids, happiness has a magical quality: Their delight at winning a race or getting a new bike is unreserved (毫不掩饰的).

    In the teenage years, the concept of happiness changes. Suddenly it's conditional on such things as excitement, love and popularity. I can still recall the excitement of being invited to dance with the most attractive boy at the school party.

    In adulthood the things that bring deep joy－love, marriage, birth－also bring responsibility and the risk of loss. For adults, happiness is complicated (复杂的).

    My definition of happiness is “the capacity for enjoyment”. The more we can enjoy what we have, the happier we are. It's easy to overlook(忽视) the pleasure we get from the company of friends, the freedom to live where we please, and even good health.

    I experienced my little moments of pleasure yesterday. First I was overjoyed when I shut the last lunchbox and had the house to myself. Then I spent an uninterrupted morning writing, which I love. When the kids and my husband came home, I enjoyed their noise after the quiet of the day.

    Psychologists tell us that to be happy we need a mix of enjoyable leisure time and satisfying work. I don't think that my grandmother, who raised 14 children，had much of either. She did have a network of close friends and family, and maybe this is what satisfied her most.

    We, however, with so many choices and such pressure to succeed in every area, have turned happiness into one more thing we've got to have. We're so self-conscious about our “right” to it that it's making us miserable. So we chase it and equal it with wealth and success, without noticing that the people who have those things aren't necessarily happier.

    Happiness isn't about what happens to us－it's about how we see what happens to us. It's the skillful way of finding a positive for every negative. It's not wishing for what we don't have, but enjoying what we do possess.
