Unchangeable Love

    One day I visited an art museum while waiting for my husband to finish a business meeting. I was expecting a quiet1 of the splendid artwork.

    A young2 viewing the paintings ahead of me3 nonstop between themselves. I watched them a moment and decided the lady was doing all the talking. I admired the man's4for putting up with her5 stream of words. 6 by their noise, I moved on.

    I met them several times as I moved7 the various rooms of art. Each time I heard her continuous flow of words, I moved away8.

    I was standing at the counter of the museum gift shop making a9 when the couple approached the10. Before they left, the man11into his pocket and pulled out a white object. He12 it into a long stick and then tapped his way into the13 to get his wife's jacket.

    “He's a14 man.” the clerk at the counter said. “Most of us would give up if we were blinded at such a young age. During his recovery, he made a promise his life wouldn't change. So, as before, he and his wife come in15 there is a new art show.”

    “But what does he get out of the art?” I asked. “He can't see.”

    “Can't see! You're 16. He sees a lot. More than you and I do,” the clerk said. “His wife17 each painting so he can see it in his head.”

    I learned something about patience, 18 and love that day. I saw the patience of a young wife describing paintings to a person without 19 and the courage of a husband who would not20 blindness to change his life. And I saw the love shared by two people as I watched this couple walk away, hand in hand.

L1 Get ahead with your English

    Many people (predict) in the 1700s that English (will) be the global languages one day, which (prove) to be the case. With the growing international companies and the great advances in communications, more and more people decide to learn English the second language. And the fact is speaking more than one language make you (stand) out. People have realized that in the (absent) of the native language environment, people can not learn it well. In words, you have to be (surround) by the language. Sadly, most of the English learners can not live in the native country, means we can only depend on our school resources.

    Australia is the smallest continent in the world. It is a little smaller than China. It is on the Southern Hemisphere of the earth. Australia is big, but its population is small. The population of Australia is nearly as large as that of Shanghai.

    Enough laws have been made to fight against pollution. The cities in Australia have little air or water pollution. The sky is blue and the water is clean. You can clearly see fish in the rivers. Plants grow very well.

    Last month we visited Perth, the biggest city in Western Australia, and went to a wild flower exhibition. There we saw large numbers of wild flowers on show, most of which we had never seen before. We had a wonderful time. Perth is famous for its beautiful wild flowers. Every year in spring Perth has a wild flower exhibition. After visiting Perth, we spent a day in the countryside. We sat down and had a rest near a path at the foot of a hill. It was quiet and we enjoyed ourselves very much. When we heard bells ringing at the top of the hills, we looked up, but what we saw made us pick up all our things and run back to our car as quickly as we could. There were about three hundred sheep coming towards us along the path.

    Australia is famous for its sheep and kangaroos. After a short drive from any town, you will find yourself among the white sheep. Sheep, sheep, everywhere you can see sheep.

    Goals are the guides all through our life. We all have goals that we are moving towards and making a great effort to achieve. This is a good thing. Or can it be bad? How many of us never reach our goals and yet we have tried so hard and really thought about nothing else? I believe the mistake most of us make is that we do not focus on our present situation.

    Let me explain. Most of us see our present situation as a stepping stone that we use simply as a means of reaching our final destination. We don't take time to truly appreciate where we are today and all the great things we already have in our lives. We should focus our attention on the journey and not on the destination, or we will miss the beautiful scenery along the way.

    Let's use our job as an example. Now most of us want a promotion. We have plans to become the manager or general manager in our companies. Unfortunately, most of us will never reach the goal, but will watch others achieve our goal instead.

    What we should be doing is focusing on the job we are currently in now. Forget where we want to get to and just focus on the present. You see, what we can control is our performance in our current job. We can decide to be the best we possibly can in our current job. Now this may mean further education to have the skills we currently do not have. It may mean working harder to produce better results than our colleagues. It could simply be a change of attitude, such as stopping complaining and becoming a more devoted and supportive employee. By doing our current job to the best of our abilities, we in fact give ourselves the best chance of promotion.

    So the best thing for all of us to do to achieve our goals is to just focus on what we have and where we are now. Do the best and be the best we possibly can in our current situations, and we will give ourselves the very best chance of reaching our goals in the future. We have heard the old sayings and they are true: “Rome wasn't built in a day.”, “Patience is a virtue”, and so on.

Have patience, have appreciation of what we already have, and take time to help ourselves be the very best we can. Do these things and we will all reach our goals, but more importantly, we will enjoy our life every day.

泥腿子

赵志广

王博刚到鹅城县当县长，就给了东风乡刘乡长一个下马威。

那天是植树节，王博轻车简从，和张秘书到东风乡检查指导植树工作，只见现场有二百多号人扛着铁锨，齐刷刷地站在一个台子前。台子上铺着红地毯，架着话筒，挂着“东风乡植树动员大会”的横幅，一个记者架好录像机，准备录像。四周彩旗招展，场面十分隆重。

刘乡长小跑着迎上来，请王博上台讲话。

王博严肃地说:“种树就种树吧，搞这个花架子干啥?都散了，马上开始干活儿吧!”

拍马屁拍到了马蹄子上，刘乡长差点儿下不来台，好在张秘书提醒了一句，才缓过神来，马上指挥这二百多号人开始挖树坑。

刘乡长让人拿过来几把柄上系着红绸的铁锨和几个鞋套，想请王博套上鞋套再去挖树坑。

王博看着不远处停着的几台机器问:“那是干啥用的?”

“那是挖树坑的机器。”刘乡长尴尬地回道。

“机器挖树坑又快又好，为啥还要这么多人挖坑?”

记者替刘乡长解释道:“王县长，虽然现在有挖树坑的机器了，可是咱得录几个镜头上电视做宣传呀!其实你不用真挖树坑，做做样子就行。”

“政府官员不是演员!干工作不是演戏!你别录了，回去吧!”王博怒斥。

记者收起录像机，灰溜溜地走了。

“刘乡长，马上让机器上阵挖坑，其他人跟在后边栽树苗、浇水，要保证成活率百分之百，不能年年栽树不见树。你记住:树在，人在；树不在，你马上走人。”王博命令。

刘乡长连连点头称是。

王博扛起几棵树苗，大步迈向挖好的树坑，泥土把鞋都弄脏了。

刘乡长也只好丢下鞋套，大步跟了上去。

那几天，马市长和各县县长亲自挖坑种树的画面在市电视台的晚间新闻中轮番播放， 唯独没有鹅城县的。邻河县赵县长的镜头最多，他干得满头大汗。

马市长为此专门打来电话，骂王博“十指不沾阳春水”，要他向赵县长学习。

王博委屈地说:“马市长，我县植树工作正在扎实推进，保证绿化率一步到位，只是没让记者录像。”

“你还是太年轻，没有政治头脑，看来还得再锻炼呀!”马市长说完挂断了电话。

一个月后，王博到东风乡检查树苗成活情况。目之所及，小树发芽抽枝，生机勃勃。树林里，有几个人正在检查和更换没成活的树苗。王博一眼认出，其中一个是刘乡长。

刘乡长见王博来了，想要握手，却又收了回去，尴尬地说:“王县长，我手上脏，不能握手了。”

王博握住刘乡长的手，笑着说:“我看你干净得很嘛!”

王博和刘乡长一起逐棵检查树苗，谈笑风生。

第二年的植树节期间，马市长和各县县长又一次亲自挖坑种树的画面在市电视台的晚间新闻中轮番播放，仍是唯独没有鹅城县的。邻河县赵县长在镜头前还是干得满头大汗。

事后，马市长打来电话问王博:“怎么又没见你们县植树的镜头?”

“我们今年一棵树也没种，根本就没有镜头可播。”王博解释道。

“一棵也没种?你这个县长还想不想干了?”马市长的语气很严厉。

“我们能种树的地儿都种上了，确实没地儿种了。”王博解释道。

马市长不听王博解释，狠狠地骂了他一顿，要他向越县长学习，接地气儿，干实事儿。

第三年植树节期间，马市长和各县县长又一次条自挖坑种树的画面在市电视台的晚间新闻中轮番播放，仍是唯独没有鹅城县的。邻河县赵县长的镜头还是最多。

马市长对赵县长的工作很满意，组织全市重要领导到邻河县观摩，只见邻河县到处都是新栽下的树苗，整整齐齐。

赵县长汇报称，前年植树五十万棵，去年植树六十万棵，今年植树七十万棵，明年计划再植树九十万棵。

王博忍俊不禁，心想:“这些数字加在一起，恐怕邻河县早变成森林了，哪里还用得着年年种树呢?”

马市长当场表扬了邻河县，表示要提拔重用像赵县长这样干实事儿的好干部，对不思进取不干实事儿的干部，要坚决免职。

王博心里郁闷，回到鹅城县后，带着张秘书去了趟绿化林。

三年前种下的树苗，早已长得高大挺拔，有的快碗口粗了。

王博摸摸这棵树，瞧瞧那棵树，爱不释手。

张秘书提醒道:“王县长，泥土把鞋都弄脏了，咱还是回去吧。”

王博低头看了看鞋上的泥土，想起了老爹的话。

王博刚当上县长的时候，老爹语重心长地对他说:“小儿呀，别以为你当个县长就是官了，其实你还是个泥腿子。泥腿子的两只脚要永远站在地上，脚踏实地干实事儿。否则，飞得越高就摔得越狠!”

想起老爹的话，王博对张秘书说:“我本来就是个泥腿子，大不了回家继续当泥腿子!”说着笑了起来，笑得张秘书不知所措。

就在王博等着被免职的时候，却传来邻河县经济数据造假被国家统计局曝光的消息。不久后，赵县长被开除了公职。

陈蕃字仲举，汝南平舆人也。初仕郡，举孝廉 ， 除郎中。遭母忧弃官行丧服阕刺史周景辟别驾从事以谏争不合投传而去太尉李固表荐征拜议郎再迁为乐安太守。时李膺为青州刺史 ， 名有威政，属城闻风，皆自引去，蕃独以清绩留。郡人周璆，高洁之士。前后郡守招命莫肯至，唯蕃能致焉。字而不名，特为置一榻，去则县之。大将军梁冀威震天下，时遣书诣蕃，有所请托，不得通，使者诈求谒，蕃怒，笞杀之，坐左转修武令。稍迁，拜尚书。性方峻，不接宾客，士民亦畏其高。征为尚书令，送者不出郭门。

延熹六年，车驾幸广成校猎。蕃上疏谏曰：“夫安平之时，尚宜有节，况当今之世，兵戎未戢，四方离散，是陛下焦心毁颜，坐以待旦之时也。又秋前多雨，民始种麦。今失其劝种之时，而令给驱禽除路之役，非贤圣恤民之意也。”书奏不纳。自蕃为光禄勋，与五宫中郎将黄琬共典选举，不偏权富，而为势家郎所谮诉，坐免归。顷之，征为尚书仆射。八年，代杨秉为太尉。蕃让曰：“齐七政 ， 训五典，臣不如议郎王畅。聪明亮达，文武兼姿，臣不如弛刑徒李膺。”帝不许。中常侍苏康、管霸等复被任用，遂排陷忠良，共相阿媚。大司农刘祐、河南尹李膺，皆以忤旨，为之抵罪。蕃因朝会，固理膺等，请加原宥，升之爵任。言及反复，诚辞恳切。帝不听，因流涕而起。

窦后临朝，蕃与后父大将军窦武，同心尽力，征用名贤，共参政事，天下之士，莫不延颈想望太平。而帝乳母赵娆，旦夕在太后侧，中常侍曹节、王甫等与共交构，谄事太后。蕃常疾之，志诛中官，会窦武亦有谋，蕃因与窦武谋之。及事泄，曹节等矫诏诛武等。蕃时年七十余，闻难作，将官属诸生八十余人，拔刃突入承明门，王甫遂令收蕃，即日害之。

论曰：桓、灵之世，若陈蕃之徒，咸能树立风声，抗论惛俗。而驱驰崄厄之中，与刑人腐夫同朝争衡，终取灭亡之祸者，彼非不能洁情志也。愍夫世士以离俗为高，而人伦莫相恤也。以遁世为非义，故屡退而不去；以仁心为己任，虽道远而弥厉。功虽不终，然其信义足以携持民心。

假如说20年前的文化发展模式尚处于1.0时代的话，那么今天已经进入2.0时代乃至3.0时代。其间，文化发展建设隶属于人类精神内容生产的根本属性没有改变，依托个人或团队扎根现实并实施文化审美内容的原创逻辑没有改变，但借以开展文化创新的媒介、工具、手段、流程。平台等发生了今非昔比的变化。因而，简单沿用1.0时代的规划套路来谋划文化发展建设，难以做到有的放矢。明智的做法，理应是顺应以下四个方面的时代变化趋势：

一是文化网络化。当今几乎所有的文化生产实践与文化投入产出，都或多或少地要和互联网发生关系。离开了互联网，很难让文化发展成果传得远、传得广。网络空间已成为当今时代最具受众关注度的文化信源和公众舆论场。实施媒体融合的第一要务就在于，传统纸媒、广电媒体等要对接融入互联网平台，实现网络化传输供给。

二是文化数字化。这可以说是媒体融合的又一个着力点所在。日常的线下文化生产供给和消费服务，一旦实现了互联网呈现及多媒体嵌入，就相当于实现了线下线上融合、新旧媒体融合。此外，优秀文化典籍、文物图像文字的保护性开发，也需借助多种手段实现数字化扫描、翻拍，存诸。展示等转化。唯有如此，才有可能让它们再现生机活力，进而真正惠及子孙后代。这同样是文化数字化的必由之路。

三是文化虚以化。这是当今时代最能以高科技手段拓展文化想象力、施展人类创新才干、再现文化时空意象的亮点所在。举凡数字电影技术中的自然灾变电脑特技、古代军团的大规模集群作战特技。科幻影视作品中的未来场景、全息投影等，都仰赖于数字虚拟技术的贡献。

四是文化算法化。算法通常和信号传输速率。计算机算力以及人工智能发达水平密切相关。当前，联网的智能手机用户已占到全民的八九成，微信、抖音等社交娱乐Ann更是全球盛行，网媒广告粘人式精准投放，社会信息借助新闻算法定点推送，这都得益于互联网传播技术尤其是4G、5G 技术的迭代进化。

应当看见，虽然文化在当今时代享受到了科技发展带来的巨大红利，但它必然还需遵循自身特定的发展规律。缺失人文的考量和谋划，足以让文化发展建设走偏、跑斜。例如，网络空间在真实创造、生产和展现人类文明发展成果的同时，也出现了像标题党泛滥。谣言四起、网络暴力、洗稿剽窃等泥沙俱下的伪文化、反文化乱象，严重干扰了公众的认知。

不管怎样，网络空间并非法外之地，更不是舆论飞地。我们必须用主流价值导向驾驭算法，使网络空间更加清朗。就此而言，即便我们主动顺应上述发展趋势，也需要在谋划“十四王”文化发展建设时“以我为主”地力争社会效益至上，进而实现社会效益与经济效益的有机统一。

拍照

苏童

每年春暖花开的时候，祖父都要去拍照。

七十岁之后，祖父习惯了以算术的角度眺望死亡，对于自己延长的寿命，他很满意。加减法是容易计算的。他五十三岁那年在点心店吃汤圆，被汤圆里的热猪油烫了一下，不知怎么引发了心肌梗塞，送到医院去抢救，结果死而复生，以此推算，已经多活了十七年。再往前的死亡事件是蓄谋的，祖父那一年才四十五岁，突然活腻了，春天他去铁路道口卧轨，人都躺下来了，火车迟迟不来，扳道工豢养的一条大狼狗先来了，祖父素来怕狗，准备好被火车碾，却不愿意被狼狗咬，于是狼狈地爬起来，逃下了铁道。到了夏天，祖父还是想死。这次他选择了水路，是从僻静的西门城墙上跳进护城河的，他以为只要扑通一下，便可简易快捷地投入死神的怀抱，没想到一睁眼，人躺在了城墙下面，一群吵吵嚷嚷的中学生围着他，好奇地打听他跳河的动机。祖父仰视着孩子们纯真的眼睛，一时拿不定主意，是该批评孩子们狗捉老鼠多管闲事，还是应该对他们说一声谢谢。他坐起来，对孩子们说了句：一言难尽。然后就爬起来，湿漉漉地走了。

祖父走出去好远了，听见孩子们在后面猜测他的去向，七嘴八舌的。有个声音说，这个人会不会又去找地方寻死了？祖父看看高处的城墙，看看低处的护城河，又抬头看看天空，忽然朝孩子们的方向折返回来。虽然他的脚步有点拖沓，但他的目光给人以新生的感觉，它像夏日的天空一样，明朗，深远。他向孩子们匆匆地表了个态，算了算了，他说，既然狼狗不让我死，你们孩子也不让我死，那我就活着好了，无所谓，死不了就活着，活一天赚一天吧。

祖父是个守信的人，从此以后果真断了轻生之念。我们香椿树街上老人特别多，老人大多怕死，怕死的大多先走了。有一年夏天气温反常，狡诈的死神藏身于热浪，在香椿树街上巡弋，一口气拽走了七个可怜的老人。祖父冒着高温酷暑，逐一登门吊唁，发现七家葬礼都缺乏组织，敷衍了事，充满了这样那样的遗憾。最离谱的是码头工人乔师傅家，儿女们居然找不到乔师傅的照片。丧幔上的遗照令人不安，那是从乔师傅的工作证上剪下翻拍的，是几十年前的乔师傅，模样还很年轻，由于乔家两个儿子与其父面貌酷肖，所以，上门吊唁的人们都大吃一惊，死者看起来不是乔师傅，这么看很像他大儿子，那么看又像他的小儿子了。祖父端详半天，心里话不宜声张，出了门便长叹一声，对邻居们说，这个乔师傅太节省了，一世人生啊，省什么都不能省那张照片，容易误会啊。

一个人无法张罗自己的葬礼，身后之事，必须从生前做起。这是祖父的信条。每年春暖花开的时候，祖父都要去鸿雁照相馆拍照，拍了好多年，连邻居们都知道了他的爱好，免不了要与他探讨这份爱好的意义。祖父对邻居们说，你们知道我脑子里有个大气泡的，气泡说破就破，我这条命，说走就走的，到时都靠他们，怎么也不放心，趁着身体还硬朗，就为自己准备一张新鲜的遗照吧。

拍照的日子是祖父的节日。节日的祖父格外讲究仪容。祖父先去理发店剃头修面，还额外要求相熟的老师傅替他挖耳屎，拔鼻毛。从香椿树街到市中心，以前祖父都是步行，现在老了，是步行加公共汽车，差不多是正午时分，他拄着一根龙头拐杖出现在鸿雁照相馆，衣冠楚楚，神色庄严，那套灰黑色的毛呢中山装上有樟脑丸的气味，皮鞋擦得锃亮，浑身散发着一首挽歌刺鼻的清香。
