采春

乔忠延

    ①冬季日短夜长。农人说，十月里天碗里转，好婆姨做不熟三顿饭。是呀，刚刚日头还在当顶，扫了扫院子，喂了喂鸡，出溜一下便滑到西山梁上去了。白日真短，短得匆匆忙忙，慌慌张张，气气喘喘。城里人也不例外，上个班两头不见太阳。早晨起床屋里黑，晚上下班外头黑，回到家里倒是亮堂，可那不是阳光，却是灯光，忙忙碌碌一天就这么过去了。

    ②日子这么紧紧张张，应该过得快吧？没有，丝毫也没有。非但没有觉得冬日短暂，一个个都感到缓慢，要不为啥总见书卷报端出现漫长的冬季呢！冬季的漫长是人们感觉出来的，不，是人们煎熬出来的。日光淡淡的，没有一点温色，寒气就像草原上的群狼到处肆虐。伸出手，手冻得疼。走几步路，脚冻得疼。手脚冻木了，不疼了，鼻尖却辣辣地疼。疼得眼睛直想流泪，却强忍着不敢流，怕流出来把冰碴子挂在脸上。这日子还能说是过吗？不，是在熬，在煎熬。一煎熬日子就长，唉，好漫长，好漫长的冬天呀！

    ③好不容易熬到立春了，可春天只在日历上露脸，天地间还是冬天的鬼样子。寒寒的，秃秃的，没有一点生机。就盼惊蛰，一天一天盼，盼来了惊蛰，似乎也没啥改观。寒还在寒，秃还在秃，要摧毁冬日根深蒂固的营盘不那么容易。没有耐心，没有韧劲，还真不行，那就打消脾气，耐下性子，慢慢熬吧！

    ④忽一日，地皮软了。踏上去不再像往日那样硬邦邦，倒似是踩在了海绵上，软软的，柔柔的。抬起头，高高的杨树梢垂挂起絮穗穗，萧疏的柳树条奓开了黄翅翅。哈呀，河边沿，垄堰根，一色的绿气正在蔓延。真让人摸不着头脑，春天却悄无声息地来了。

    ⑤好啊，春来了！

    ⑥春来了，哪里还能在屋里憋得住？憋屈了一冬天的肢体早该展放了，憋闷了一冬天的浊气早该释放了。街市上不行，挤窄；村巷里不行，弯折。只有阔野，只有山梁，才是展放肢体、释放浊气的理想地方。二月二，龙抬头。人们出了城，出了村，原野里、山梁上到处是人。小路上是人的溪流，大路上是人的河流，平地上是人的海洋，山巅上是人的峰峦。随便拦住一个打问，这是干什么？回答简练干脆：采春。

    ⑦采春！

    ⑧采春？怎么个采法？采法不复杂。满地是春气，走一走浑身是春情；小溪流春水，洗一洗满脸是春意；山壑荡春风，爬一爬萦怀是春温。更别说，枯树丛里的松树叶柏树叶早变绿了，绿得像是点缀的翡翠；更别说，崖壁岩角的连翘花山桃花早已开了，粉嘟嘟的像是仙女的笑靥。有人手痒了，折一节松枝带回去，往花瓶里一插，满屋子清香，春天的气息驱走了冬日的萎靡。有人心痒了，掐一朵粉桃花簪在乌黑的头发上，走到哪儿，都是笑笑的，笑开了一个人见人爱的春温时令。采春，采出的是欢乐，采出的是笑颜！

    ⑨还有人比他们更贪婪，见到春色手也痒，心也痒。手痒没动手，心痒大动心，把那春意、春情、春光，甚而春枝春叶、春蕾春花，装满一肚子，塞满一脑子。回到家里放不下，躺在床上推不开，睡在梦里仍是春水流淌，春鸟啼鸣，春条喷绿，春花怒放……梦醒了，人未醒，反而醉得迷迷离离，痴痴幻幻。迷离中展开纸，痴幻中拿起笔，于是，世人看见：“绿柳才黄半未匀”，那是杨巨源采回来的春天；“二月初惊见草芽”，那是韩愈采回来的春天；“昨日春如十三女儿学绣，一枝枝不教花瘦”，那是辛弃疾采回来的春天；“离离原上草，一岁一枯荣。野火烧不尽，春风吹又生”，那是白居易采回来的春天。

    ⑩凡人采回的青枝绿叶，香着香着淡了，散了；凡人采回的蓓蕾花朵，开着开着败了，干了。而诗人采回的春天，却永恒地绿着，香着。白居易的春草，从唐朝绿满书卷，绿到了今天；辛弃疾的春花，从宋代香满庭堂，香到了今天。

    Last year my summer holiday was spoiled by my bringing along a modern convenience that was too convenient for my own good: the iPad. Instead of looking at nature, I checked my e-mail. Instead of paddling a small boat, I followed my Twitter feed（推特简讯）. Instead of reading great novels, I stuck to reading four newspapers each morning. I was behaving as if I were still in the office. My body was on vacation, but my head wasn't.

    So this year I made up my mind to try something different: withdrawal from the Internet. I knew it wouldn't be easy, since I'm bad at self-control. But I was determined. I started by giving the iPad to my wife.

    The cellphone signal at our house was worse than in the past, making my at tempts at cheating an experience in frustration （沮丧）. I was trapped, forced to go through with my plan. Largely breaking away from e-mail, Twitter and my favorite newspaper websites, I had few ways to connect to the world except for the radio—and how much radio can one listen to, really? I had to do what Ihad planned to do all along: read books.

    This experience has had a happy ending. With determination and the strong support of my wife, I won in my vacation struggle against the Internet, realizing finally that it was I, not the iPad, that was the problem. I knew I had won when we passed a Star bucks and my wife asked if I wanted to stop to use the Wi-Fi.“I don't need it,” I said．

    However, as we return to post-vacation life, a harder test begins: Can I continue when I'mback at work?

    There are times when the need to know what's being said right now is great. I have no intention of giving up my convenience completely. But I hope to resist the temptation to check my e-mail every five minutes, which leads to checking my Twitter feed and a website or two.

    I think a vacation is supposed to help you rest your brain to become more productive. Here I hope this one worked.
