家之脉

陈忠实

      ①1950年春节过后的一天晚上，在那盏祖传的清油灯之下，父亲把一支毛笔和一沓黄色仿纸交到我手里：“你明日早起去上学。”我拔掉竹筒笔帽儿，是一撮黑里透黄的动物毛做成的笔头。父亲又说：“你跟你哥伙用一只砚台。”

      ②我的三个孩子的上学日，也是我们家的庆典日。在我看来，孩子走进学校的第一步，认识的第一个字，用铅笔写成的汉字第一画，才是孩子生命中光明的开启。他们从这一刻开始告别黑暗，走向智慧人类的途程。

      ③我们家木楼上有一只破旧的大木箱，乱扔着一堆书。我看着那些发黄的纸和一行行栗子大的字问父亲：“是你读过的书吗？”父亲说是他读过的，随之加重语气解释说：“那是你爷爷用毛笔抄写的。”我大为惊讶，原以为是石印的，毛笔字怎么会写到和我的课本上的字一样规矩呢？父亲说：“你爷爷是先生，当先生先得写好字，字是人的门脸。”在我出生之前已谢世的爷爷会写一手好字，我最初的崇拜产生了。

      ④父亲的毛笔字显然比不得爷爷，然而父亲会写字。大年三十的后晌，村人夹着一卷红纸走进院来，父亲磨墨、裁纸，为乡亲写好一副副新春对联，摊在明厅里的地上晾干。我瞅着那些大字不识一个的村人围观父亲舞笔弄墨的情景，隐隐感到了一种难以言说的自豪。

      ⑤多年以后，我从城市躲回祖居的老屋，在准备和写作《白鹿原》的六年时间里，每到春节前一天后晌，为村人继续写迎春对联。每当造房上大梁或办婚丧大事，村人就来找我写对联。这当儿我就想起父亲写春联的情景，也想到爷爷手抄给父亲的那一厚册课本。

      ⑥我的儿女都读过大学，学历比我高了，更比我的父亲和爷爷高了。然而儿女唯一不及父辈和爷辈的便是写字，他们一律提不起毛笔来。村人们再不会夹着红纸走进我家屋院了。

      ⑦我小时候有回晚上下了一场大雪，足足下了一尺厚。第二天上课心里都在发慌，怎么回家去背馍呢？50余里路程步行，我13岁。最后一节课上完，我走出教室门就愣住了，父亲披一头一身的雪迎着我走过来，肩头扛着一口袋馍馍，笑吟吟地说：“我给你把干粮送来了，这个星期你不要回家了，你走不动，雪太厚了……”

      ⑧二女儿因为读俄语，补习只好赶到高陵县一所开设俄语班的中学去。每到周日下午，我用自行车带着女儿走七八里土路赶到汽车站，一同乘公共汽车到西安东郊的纺织城，再换乘通高陵县的公共汽车，看着女儿坐好位子随车而去，我再原路返回蒋村的祖屋。我没有劳累的感觉，反而感觉到了时代的进步和生活的幸福，比我父亲冒雪步行50里为我送干粮方便得多了。

      ⑨父亲是一位地道的农民，比村子里的农民多了会写字会打算盘的本事，在下雨天不能下地劳作的空闲里，躺在祖屋的炕上读古典小说和秦腔戏本。他注重孩子念书学文化，他卖粮卖树卖柴，供给我和哥哥读中学，至今依然在家乡传为佳话。

      ⑩我供给三个孩子上学的过程虽然也颇不轻松，然而比父亲当年的艰难却相去甚远。从做私塾先生的爷爷到我的孙儿这五代人中，父亲是最艰难的。他已经没有了做私塾先生的爷爷的地位和经济，而且作为一个农民也失去了对土地和牲畜的创造权利，而且心强气盛地要拼死供给两个儿子读书。他的耐劳他的勤俭他的耿直和左邻右舍的村人并无多大差别，他的文化意识才是我们家里最可称道的东西，却绝非书香门第之类。

      ⑪这才是我们家几代人传承不断的脉。

    Do you ever find yourself getting really unhappy for almost no reason? Or suddenly feeling down without knowing why? Going from sadness to anger to joy in a matter of minutes can make many teens feel as though they're losing control. But why is the feeling so common among teens?

    Maybe you're starting a new school and not able to see old friends as much. Getting good grades or wanting to be better in sports or other activities can be a concern (关注) for many teens.

    Being accepted by friends is important. Teens also may notice, for the first time, a sense of distance from parents and family. You may feel you want to be on your own and make your own decisions, but it can also seem a bit lonely at times.

    Another important cause for mood swings is biology. When puberty (青春期) begins, the body starts producing hormones (荷尔蒙). These hormones cause physical changes in the body. But in some people, they also seem to cause emotional (情绪的) changes.

    Here are some things you can do that might make those bad moods a bit easier to deal with.

    Recognize you're not alone. Although not every teen experiences mood changes to the same degree, they are common.

    Talk to people you trust. Friends can help each other by realizing that they're not alone in their feelings. Talking to parents is important, too. Parents can share their own experiences dealing with bad moods. Teachers are often good resources and a doctor can help to answer questions about development.

    Get enough sleep. Though it can be hard to find enough time, getting enough rest is very important. Being tired can lead to more sadness.

    Create. Taking part in some kinds of activities, like building something out of wood, or starting an art or music piece. Writing can help you organize and express your thoughts and feelings. Get your thoughts on paper. Do the same thing with paint, music, or other art forms. Put your feelings into your artwork.
