错把异乡当故乡

苏童

选择南京作居留地是某种人共同的居住理想。

十八岁离开家乡以前，我所去过的最远的一个城市就是南京，那是一次比较特别的旅行，不是为了游览，不是为了探亲，当时有来自全省的数百名中学生聚集在建邺路上的党校招待所里，参加一个大规模的中学生作文竞赛，那次竞赛我名落孙山。

记得在返回苏州之前我们一大群人停留在火车站前的广场上，忽然发现玄武湖就在眼前，不知是谁第一个跑到了湖边，我们纷纷尾随过去，也不知是谁第一个在湖边开始洗手，一大群中学生沿着湖岸一字排开，大家都把手伸进湖水里，很认真地洗了一回手。我至今仍然记得那群蹲在湖边洗手的少男少女的样子与笑声，二十年过去以后所有人手上的玄武湖水已经了无印痕，而我却在无意之中把那捧湖水融进了我的未来。当年那群等待回家的苏州中学生中，也许只有我一个人日后留在了玄武湖边。

选择南京作居留地是某种人共同的居住理想，这种人所要的城市不大不小，不要繁华喧闹也不要沉闷闭塞，不要住在父母的怀抱里但也不要离他们太远，这种人无须拥有自己的花园却希望他居住的城市风景如画，这种人希望自己智商超群精明强干却希望别人纯朴憨厚关心他人，我大概就是这种人，所以在我二十二岁那年我自愿成为一个南京人，至今已经做了十几年的南京人，越做越有滋味。

除了冬夏两季的气候遭到了普遍的埋怨，南京几乎是一个人见人爱的地方。许多城市是绿化城市，但南京街道上的华盖似的梧桐却无与伦比（南京人溺爱这些树因而原谅了春天树上飘下的茸毛，春天你可以看见许多骑自行车的人在头上、身上拍打那些茸毛，脸上的表情却无怨无恨）。许多城市都有一个或几个值得本地人骄傲的风景区，外地人去了就褒贬不一，但是南京的中山陵是一种王尊地位。当你登临中山陵最高处极目四眺，方圆数里之内一片林海，你会发现这个城市之美不同凡响，紫金山与长江不再是什么天然屏障，它们使南京永远受到了山水的孕育。东郊的林海则是一只巨大的绿色的枕头，每天夜里它对着太平门耳语一声，睡吧，南京，南京就睡了；每天早晨它对着中山门说，醒来吧，南京，南京就醒来了。

六朝古都的睡眠不会太长，南京醒来了，在从前帝王们的车马经过的地方，南京人的自行车匆匆而过。在新街口一带的工地上，打桩机根本不顾明孝陵下太子妃的幽魂对噪声有何看法，一心要为建设新南京而发出它的狂叫。在城南的某条古老的小巷里，某个老妇拎着一只古老的马桶走过古老的秦淮河，但是她已经不能随手在河里倒马桶，她必须把它倒在公共厕所的化粪池里——南京虽然还没有消灭马桶，但是就连上海都还没有消灭马桶呢，南京为什么要这么着急呢。

着急不是南京人的性格，虽然南京人说话听上去显得很着急。这几年人人都想发财，南京人也想得慌，但是他们因为不着急，许多事就比别的地方慢半拍。当南京人来到深圳海口淘金时，那里已经人满为患，他们就回来了。当南京人发现别人生产假货劣货大发其财时，他们伤心地意识到作为一个南京人是发不了这种大财的，他们于是就想发小财。他们想还是回家做盐水鸭，反正南京人吃盐水鸭吃不够，即使卖不掉也没关系，反正自己也吃不够。

南京人也符合我对人群的理想，所以我在南京一直生活得自得其乐。今年夏天的某一天，忽然游性大发，想到在南京这么多年，许多朋友嘴里的幽美之地还没去过，就携妻子女儿往东郊而去。因为不是假日，游人寥寥，一家人从藏书阁小径进入百年树荫，一路探幽至灵谷寺，途中不闻人声但闻鸟语流泉，心中便有一种奇异的甜蜜感觉，好像这个地方是自己家的，好像是自己向自己炫耀了一件宝物，结果自己很满足，也很幸福。

也许这很自然，一个人如果喜欢自己的居住地，他便会在一草一木之间看见他的幸福。多少人现在生活在别处，在一个远离他生命起源的地方生活着，生活得没有乡愁，没有哀愁，生活得如此满足，古人所谓“错把异乡当故乡”的词句大概也就源于此处吧。

    Kyle Schwartz, a new teacher at Doull Elementary School in Denver, teaches a third-grade class. Most of  her students come from underprivileged homes, as 92 per cent are entitled (给予权利) to free or reduced school lunches, she said.

    "As a new teacher, I tried to understand my students' real lives and how to best support them. I just felt like there was something I didn't know about my students," she said. To solve this problem, she asked her students to complete the sentence: "I wish my teacher knew."

    While some children used the notes to jokingly complain(抱怨) about homework or to ask for more playtime, Ms Schwartz said some of the answers were "heartbreaking", as children showed their hard lives. One student told Ms Schwartz that he did not have any pencils at home, while another said that they hadn't seen their father for six years. And another student wrote, "I wish my teacher knew sometimes my homework is not signed (签字) because my mom is not around a lot. "

    She posted them to Twitter in March with the hashtag "I Wish My Teacher Knew". Teachers on Twitter soon noticed how successful Ms Schwartz's trick(策略) was for reaching out to students, and began sharing similar notes they received alongside "I Wish My Teacher Knew."

    Ms Schwartz said that since she encouraged her students to share their secrets, students have been supporting each other more, and she hopes the method will connect students and their families with the proper resources (资源) they need to live comfortably. She added that the results have been surprising, and the student that said she didn't have anyone to play with has since been invited by classmates to join them on the school playground.

    In Albuquerque, New Mexico, high school students wanted to tell other students about Buy Nothing Day.

    The first time I went to Beijing Zoo was several year ago with my father. I clearly remembered that it was a Sunday in October. We joined a tour group and set off early than usual. I enjoyed the beautiful scenes along the way because I was exciting. It took us about three hours to arrive here. On arriving, I jumped off the bus and went straight see pandas. They were very lovely that I kept taking photos. Then I had paid a visit to the aquarium, where there have thousands of fishes and other sea creatures. The experience left a impression on me.
