题干

材料一:中国宏观经济增速放缓,已由短缺向过剩时代转变。以钢铁业为例,过去只要炼出钢,都能卖出厂,现在只有质量优,才能投资生产。包括工人工资在内的生产要素价格“变贵”。据统计,中国工人的成本,2010年相当于美国的7%,估计2015年相当于美国的17%,中国制造业的成本优势将消失。随着人们对环境问题的日益关注,根据“污染者付费”原则,企业的环境成本将内在化,靠牺牲环境的低环境成本道路已行不通。中国企业的这些传统优势正不断被削弱。

材料二:中国企业不断提升对外开放水平。从对1500家出口型企业的调查来看:1500家企业中出口国家和地区在20个以上的,从2007-2011年上升了9%,出口目的地更加多元化,除了传统的欧美市场之外,新兴国家、发展中国家的出口正不断增加;50%以上的企业非制造环节对企业总利润贡献达到31%(非制造环节包括了研发设计、产品销售、渠道等),企业研发投入不断增加,中国的企业正在越来越多地从价值链的低端向价值链高端转移;50%以上的企业自有品牌产品的销售收入达到90%。2015年9月份,中国铁路国际(美国)有限公司与美国西部快线公司签署协议,合作建设经营美国西部快线高铁。“中国速度”已经在世界市场占有一席之地。中国装备的“走出去”,有效化解了我国产能过剩,带动了国内产业调整和发展。

                                                                     The Diet Zone: A Dangerous Place

    Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically.

    Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale(秤)instead. All we have to do is to swallow or recognize the word “diet” in food labels.

    On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don't have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.

    The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients. Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemicals that go into diet products are potentially dangerous.

    Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological and physical harm that comes from using them.
