谁的心中不曾有过远方

张铁

      “世界那么大，我想去看看”，当微信朋友圈被北京的沙尘暴刷屏，这句话给人的“小清新”之感，更显强烈。近日，河南一位女教师这封“最有情怀，没有之一”的“辞职申请”，引起无数人共鸣。

      念念不忘，必有回响。一句话撩动心弦，正是因为它以一种诗意的方式，说出了不少人心中的渴望。从朝九晚五的按部就班中跳出来，从办公桌边的循规蹈矩里跳出来，打破思维方式的条条框框，摆脱现实生活的患得患失，拥抱一个更广阔也更精彩的世界。即便这个世界可能只是一种美好的想象，但谁的心中没有激荡过一个远方？

      电影中，有一种特殊的类型叫“公路片”。主角们走过漫长得似乎没有尽头的旅程，不管是不是能抵达，都会经历精神的考验，收获心灵的成长。“看世界”与“在路上”，其实有着一致性，不一定是逃避，也不一定要彷徨，就是为了遇到一个更好的世界，也成就一个更好的自己。相信，行遍大千世界、看过人生百态，这位女教师如若再次站上讲台，应该能讲出不一样的精彩。一个正常的社会，也应该是一个有活力有机会的社会。当人生出彩的舞台越来越广阔，也更加刺激了“出走”的渴望。女教师的选择本身，就是一个例子。现实中，过去鲜见的公职人员辞职，也不断见诸报端。温州平阳原副县长周慧的辞职信，也写得很文艺，“每个人都应该遵循自己内心的想法去选择自己的生活”。的确，有了更多的机会，人生也就有了更多的可能﹣﹣虽然每一次选择都不免纠结。

      说到底，渴望远方，还是因为现实的砝码更重一些，让说走就走的旅行难以成行。黄土涵养农耕，农耕孕育家庭，数千年的中华文明，让生存状态的“稳定性”，成为这种文化所化之人最基本的诉求。学者认为中国社会有着“超稳定结构”，其实，从安土重迁的观念到家族聚居的方式，中国人的心灵世界又何尝不是如此？这或许也是一些稳定的职业有着很强吸引力的原因。在这样一种文化中，“现世安稳”是一种扯不断的心理牵挂、情感羁绊。

      身处开放的环境、面对信息化的洪流，“世界”是个诱惑十足的词。然而，在竞争激烈、“压力山大”的社会中，面向大海的转身难以避免地遭遇更多艰难。“外面的世界很精彩，外面的世界很无奈”，或许，去世界看看的人们，终究还是要面对“娜拉出走之后”甚至“娜拉回来之后”的问题。“出门看世界”和“回到老地方”，成为当今中国人一组难以解开的心结，惟有在朋友圈里徒然羡慕着远方。

      对于“想去看世界”的辞职，虽然点赞者甚众，但真正能“从心动到行动”的，在这样的社会里不应该也不可能成为主流。毕竟，情怀不能当饭吃，甜点也不能当正餐。辞职的女教师去“看世界”了，更多的人却选择了留下来，在讲台上继续自己的事业，换个角度看，没去看世界者不才是这个社会的基石吗？

      “世界那么大，我想去看看”，看起来文艺腔十足的表达，背后是时代的发展、文化的演进，诠释着社会心理结构的变迁。其实，生活充实，何必别处？心有梦想，何必远方？过好每一天，走好每一步，未尝不是同样精彩的人生。

根据短文理解，选择正确答案。

    Urban swans might be born with a daredevil gene that makes them less fearful of humans, compared with their rural colleagues.

    A study has found swans living in cities tend to be bolder and it is at least partly determined by a gene called DRD4. Birds with this gene could therefore be better adapted to settling in more populated areas, while more timid（胆怯的）swans would escape to less inhabited regions.

    It could help to explain why swans in public parks and on urban rivers have a reputation for being so aggressive towards humans - they are simply not afraid of us.

    Biologists from some universities in Australia, tracked and collected blood samples from black swans living in two wetlands near cities. One group of swans lived in a recreational urban park, while the other occupied a waste-water processing site out of town. The two areas were less than 20 miles apart. Later, from 2011 through 2013, the researchers started systematically scaring the swans at both sites. The researchers approached the birds and calculated how close they could get before they flew away. As expected, they noticed that while rural swans started flying away if a human was closer than 119 meters, the scientists could come as close to urban swans as 39 meters before taking off.

    Analyses of the blood samples, in fact, showed that 83 per cent of the less cautious swans presented the same genetic DRD4 variation（变异)while rural swans have different genetic makeups resulting in more wariness(谨慎，小心）.

The researchers conclude that swans with the bold variation of the gene might choose to live in urban environments, as they tend to be less bothered by human presence.
