备战2014考研全程详细规划
考研，一个孤独而磨练自己的过程。这段奋斗的日子，除了教材、资料、老师，还应该有自己的考研备战规划。为此，特别推出八大板块，助你考研复习.
一、精神层面
1、坚持走到最后，每天坚持进自习室学习四个小时。
2、放弃。放弃与考研无关的事情，放弃你可能就业的机会.
3、忍受孤独、寂寞及别人对你的不理解甚至讥笑。你要坚持你的理想与信仰。
4、能承担第一年失败的结果，从今天起不要再思考“我考不上怎么办”相信自己告诉自己：“我一定能考上”，勤奋，执著，一根筋。二、全程规划

4.、全年规划——安排好细节，有所取舍。做精神食粮的准备
原因:考研分四个时间段：现在——四月亢奋期；5——8月量变，9、10迷茫期，11、12平静质变。很多人在9/10月放弃，做精神食粮的准备就是为了突破迷茫期。
方法：一般是考研之初准备励志书、励志音乐电影；或者储备现在的
激情，（盲目乐观型幻想症）如写考研日记，录音日记，把自己对自己的承诺记录下来，还有每次的收获对自己的鼓励，记录生命的精彩，享受考研，快乐考研。

Today we have a(an) _14 _ to label obesity as a disgrace.The overweight are sometimes_15_in the media with their faces covered. Stereotypes _16_ with obesity include laziness, lack of will power,and lower prospects for success.Teachers,employers,and health professionals have been shown to harbor biases against the obese. _17_very young children tend to look down on the overweight, and teasing about body build has long been a problem in schools. Negative attitudes toward obesity, _18_in health concerns, have stimulated a number of anti-obesity _19_.My own hospital system has banned sugary drinks from its facilities. Many employers have instituted weight loss and fitness initiatives.

2006年的一部电影《穿普拉达的女王》有段情节这样演绎：Meryl Streepb扮演的Miranda Priestly,，斥责她毫无吸引力的助手，因为她反映高端时尚并不能感染她，然后Priestly说明了助手毛衫的深蓝色是如何从时尚展览中慢慢伸展到百货商店再到平价店中，毫无疑问是这个可怜女孩挑选了这件衣服的地方。 时尚业管理严密的理念已经非常过时了，或与Elizabeth Cline对“快餐时尚”的这三年的控诉书《过度装扮》中所描述的狂热不一致。在过去的十几年里，技术的发展使得像Zara，H&M，Uniqlo等的一些大众市场商标更快地对趋势做出反应，更精确的抢占市场需求。更快地周转意味着更少的库存浪费，更频繁的发布，更高的利润。这些商标煽动那些关心样式的消费者把衣服当做只洗一到两次的一次性物品，而且，他们不做广告，并每隔几周就全部更新店面的衣服。Cline认为，这些品牌以极低的价格提供潮流商品的这种行为是在抢劫时尚圈，动摇了这个产业长久以来惯有的季节性。 这次变革的受害者不仅仅是设计者。对于H&M来说，为其全球2300家分店提供一个5.95美元的编制迷你裙必须依赖海外的廉价劳动力，大量的耗尽自然资源的订单，大量的有害化学品。 《过度装扮》是时尚界对像Michael Pollan的The Omnivore’s Dilemma这样的消费者权益维护者的畅销书的回答。“大量生产的衣物就像快餐，满足饥饿和需求，还是一次性的，浪费的，”Cline认为。她还发现，美国人一年大概要买200亿件衣物-平均每人64件一年-不论他们是花费了多少钱，这种不节制导致极大的浪费。 在《过度装扮》的最后部分，Cline介绍的她理想的典范，一个布鲁克林的女人Sarah Kate Beaumont,从2008年开始自己制作自己所有的衣物，并且毫不逊色。但是像Cline记录的那样，Beaumont花了十年时间完善她的手艺；这个例子不该被忽略。 虽然许多快餐式时尚公司已经努力控制对劳动力和环境的消极影响，包括H&M公司的绿色循环生产线，Cline依然相信只有消费者的改变才能对此产生长久的改变。她提出对于多数可持续发展（不论是对于食物和能量）的支持者都同有的理想。浮华在继续着；只有在被逼无奈之下人们在消费时才会考虑到可持续性。 Version 描述，说法，叙述，解释，译文，版本 scold 责骂，斥责 Sweat汗水衬衫 descend 下降，遗传，屈尊 bargain 交易，契约讨价还价v garment Conception Top-down 管理严密的 at odds with不一致 Feverish狂热 Indictment控告，起诉书 react Anticipate占领 Precisely精确 disposable wardrobe hijack
