    Emily and her boyfriend had just had a fight. She felt alone and hopeless. Then she went into the kitchen and grabbed what she needed before going back up to her room quietly. She switched on the TV and started eating…and eating…for hours, until it was all gone.

     What Emily didn't know at the time was that she was suffering from an illness called binge-eating disorder(BED)(暴饮暴食).

    For years, Emily didn't tell anyone what she was doing. She felt ashamed, alone, and out of control. Why don't famous people confess (承认) to BED, as they do to anorexia? It's simple: There's a stigma(污名)involved. “Overeating is seen as very bad, but dieting to be skinny is seen as positive and even associated with determination," says Charles Sophy, a doctor in Beverly Hills , California.

    "Some parents or friends may look at a teen with BED and think, 'Oh, a good diet and some will-power will do the trick.' But that's not true," says Dr.Ovidio Bermudez , a baby doctor at the Eating Recovery Center in Denver. "Eating disorders are real physical and mental health issues; it's not about willpower." The focus in treating BED shouldn't be on weight, because as with all eating disorders, the behaviors with food are a symptom of something deeper.

    Like most other diseases, genetics may play a big part in who gets BED and who doesn't. If you have a close relative with an eating disorder, that means you're more likely to develop an eating disorder of your own.

    Besides, many people with BED have tried at some point or another to control it by going on a diet, but paying more attention to food doesn't help. And it might even make things worse, like it did for Carla, who's 15 now and is recovering from BED. "My parents would always tease me about my weight, so when I was 14, I went on a very restrictive diet," she says. When you can't have something, you only want it more, so every time Carla would have a bite of something that wasn't allowed on her strict diet. She would quickly lose control and binge (狂欢).

材料一:近年,中国高铁的发展速度突飞猛进,已渐渐成为广大旅客首选的出行交通工具,那么,高铁究竟为何如此受旅客们的青睐呢?

从最初的“绿皮车”到快速列车,速度的提升缩短了旅程,拉近了人们的距离。对于高铁,速度更是在快速列车的基础上翻了一番,在这个生活节奏愈来愈快的时代,跟时间赛跑的观念早已深入人心。

坐过高铁的都知道,高铁舒适度高,服务质量跟航空不相伯仲,细节也是追求尽善尽美。不仅提供无线wifi、充电插座、沙发床、平板电脑等用品,而且商务座还有乘务员贴心服务。

说到服务,就要谈一谈价格了。众所周知,同里程的高铁价格是低于航空价格的,出行千里仅百元。近期铁路集团投入的“高铁快运”服务,货运价格也低于其他快递行业,而且朝发夕至,效率可见一斑。

材料二:我国遵循“引进先进技术,联合设计生产,打造中国品牌”的指导方针,高铁技术实现了“引进技术——中国制造——中国创造”的三阶段跨越式发展。中国高铁,已成为中国装备制造业最具全球影响力的代表符号之一,同时也是“中国创造”的最佳诠释。尤其是,高铁的核心部件——牵引电传动系统和网络控制系统,已成功实现百分之百的“中国创造”。

目前,我国是世界上高速铁路系统技术最全、集成能力最强、运营里程最长、运行速度最高、在建规模最大的国家。中国高铁,这个最美的国家名片正快速走向世界。

材料三:4月21日起,铁路部门对东南沿海部分高铁票价进行优化调整。以福州至厦门北高铁为例,调整前二等座执行票价为715元,调整后为845元,上涨18%;一等座由855元调整至134元,上涨57%。
