Unit 4 Unit 4 letslets go go*No one realizes how beautiful it is to travel until he comes home and rests his head on his old,familiar pillow.Certainly,travel is more than the seeing of sights,it is a

analysis第24页1.早晨四点一刻，闹钟把我从美梦中惊醒，要不是突然看见早已收拾好行李箱，我几乎又要睡着。想起来还要去机场，我叹了口气。出租车来晚了，而且在途中迷了路，我越来越担心会赶不上飞机。出租车一到机场我就冲进去，跌跌撞撞经过安检处，终于，我来到了登机口。经历这一早全部麻烦事，我乘坐航班却被取消了。在接下来 218 分钟里，我被困在了机场，唯一以为抚慰是机场提供一杯无偿咖啡。这就是旅行，让人心烦跑跑停停。最终，在不知经过多少小时之后，终于抵达要去地方。返回第25页2.我们为何要旅行？其实，我并不介意飞行本身，在这么一个密实金属大鸟中飞行，让我感到很奇妙。然而，旅程其余部分，从一大早X光检验到出售大堆纪念品糟糕机场商场，感觉就像是关于当代社会弊病乏味课程。这是全球化结果，它糟糕透了。返回第26页3.当然，有时候我们旅行是因为我们需要去旅行。因为即使在这个数字化时代，我们依然有一些很主要事情要去做，比如在商务午餐中与生意搭档握手，或是在感恩节这天吃上妈妈尤其准备食物，或是在你和你女朋友两周年纪念日这天去看她。返回第27页4.不过大多数旅行是可去可不去，在超出 50 英里旅行中，只有 30%属于真正必需商务旅行。我们旅行是因为我们想要去旅行，因为到一个新地方兴奋和激动能够抵消在机场各种烦心事；因为工作压力太大，我们血压太高，我们要去热带地域度假；因为在家实在太无聊；因为航班都在打折；因为巴黎毕竟是巴黎。返回第28页5.多亏了当代航空技术，我们现在能够以非凡速度在空中穿梭。在人类历史中，这是我们第一次超出太阳在短短一天中从一个半球抵达另一个半球。当然，仅仅往飞机上一坐是不够。我们要想认识到旅行在提升创新力方面价值，还得再全方面考虑其目标。毕竟，大多数人逃到巴黎，是因为这么他们就能够无须考虑家里那些烦心事。不过，含有讽刺意味是，当我们坐在豪华左岸咖啡馆时，我们脑子极有可能能处理那些最棘手问题。所以，我们应该考虑那些在家里处理不了问题，而不是琢磨那些奶油甜点。返回第29页6.但更应该知道是我们思想被熟悉东西所充满。大脑是一个几乎含有没有限可能性空间，这就意味着它花了大量时间和精力选择不去注意什么。所以，我们牺牲创造力来换取效率。我们以字义明确散文方式思索，而非以含有象征意义诗歌方式思索。然而，一点距离就能够帮助我们放松禁锢我们认知链条，使新旧思想结合更轻易，对平淡无奇事情可从更抽象角度加以认知。有研究指出，体验异国文化能够赋予我们宝贵开放性思维，使我们更轻易明白即使是微不足道事物也能够有各种意义。想一想把食物剩在盘子里这个行为：在中国，这通常被看成是一个赞美，说明主人提供了足够食物。不过在美国，一样行为却暗含欺侮，表明食物不够好，人们不愿意吃完。返回第30页7.这种多元文化对比说明，经验丰富旅行者会接收对事物多样性解读，他们欣然认识到对这个世界能够有截然不一样（但却一样有效）方式进行解释。这也从而让他们扩大了“认知输入”范围，因为他们拒绝仅仅满足于他们最初答案和先前猜测。返回第31页8.当然，这种思维灵活性不但仅来自纯粹距离改变，即简单经纬度改变。相反，这种创造力复兴似乎是差异所带来副产品：我们需要处于不一样文化中，体验人类传统中纷繁复杂多样性。在国外旅行中让人迷惑同一个方面问题（如我该给服务生小费吗？火车要把我带到哪里？），产生了一个持久影响，使我们愈加含有创造性，因为我们不再那么视野狭隘了。我们了解了我们不知道东西，而这些东西几乎涵盖了一切；我们对接连不停惊喜感到惊奇。即使在这个全球化时代，我们依然会对全部未包含在旅行指南中、日常东西感到惊奇，而这些东西在自己家中也不存在。返回第32页9.当然，我们也并不是假装旅行没有缺点，或是说我们忍受飞行时差综合反应只是为了消遣。在卢浮宫我们迷路十个小时，那不是因为我们喜欢迷路。我们站在马丘比丘古城遗址顶端俯瞰风景可能也并不能填补我们丢失行李麻烦。（通常，我在假期结束后还需要一个休假。）我们旅行是因为我们需要旅行，因为距离与差异是创造力秘密基石。我们回家后，家还是那个家，不过我们思维已经有所改变，而这就能够改变一切。返回第33页Structure
