2016年考研英语一真题及答案
2016 年全国硕士研究生入学统一考试英语（一） 真题及答案（完整版） Text 1 France, which prides itself as the global innovator of fashion, has decided its fashion industry has lost an absolute right to define physical beauty for woman. Its lawmakers gave preliminary approval last week to a law that would make it a crime to employ ultra-thin models on runways. The parliament also agreed to ban websites that" incite excessive thinness" by promoting extreme dieting. Such measures have a couple of uplifting motives. They suggest beauty should not be defined by looks that end up with impinging on health. That's a start. And the ban on ultra-thin models seems to go beyond protecting models from starring themselves to health -as some have done. It tells the fashion industry that it move take responsibility for the signal it sends women, especially teenage girls, about the social tape -measure they must use to determine their individual worth. The bans, if fully enforced ,would suggest to woman （and many men ）that they should not let others be orbiters of their beauty .And perhaps faintly, they hint that people should look to intangible qualities like character and intellect rather than dieting their way to sine zero or wasp-waist physiques . The French measures, however, rely too much on severe punishment to change a culture that still regards beauty as skin-deep-and bone-showing. Under the law, using a fashion model that does not meet a government-defined index of body mess could result in a $85,000 fine and six months in prison. The fashion industry knows it has an inherent problem in focusing on material adornment and idealized body types. In Denmark, the United States, and a few other countries, it is trying to set voluntary standard for models and fashion images there rely more on pear pressure for enforcement. In contrast to France's actions, Denmark's fashion industry agreed last month on rules and sanctions regarding age, health, and other characteristics of models .The newly revised Danish Fashion Ethical charter clearly states, we are aware of and take responsibility for the impact the fashion industry has on body ideals, especially on young people. The charter's main toll of enforcement is to deny access for designers and modeling agencies to Copenhagen. Fashion week, which is men by the Danish Fashion Institute .But in general it relies on a name-and -shame method of compliance. Relying on ethical persuasion rather than law to address the misuse of body ideals may be the best step. Even better would be to help elevate notions of beauty beyond the material standards of a particular industry. 21. According to the first paragraph, what would happen in France [A] Physical beauty would be redefined [B] New runways would be constructed

2016考研英语二真题：小作文解析
2016考研英语二真题：小作文解析 Suppose you won a translation contest and your friend Jack wrote an email to congratulate you, and ask advice on translation. Write him a reply to 1)thank him; 2)give your advice. You should write neatly on the ANWSER SHEET. Do not sign you own name at the end of the letter, use “Li Ming ” instead. Do not write the address .(10 point) 如大家所见，这是2016年英语二小作文题目。英语（二）考纲的写作部分，其实主 要考查学生的应用能力，考查范围包括私人和公务信函、备忘录、报告等，还应能写一般 描述性、叙述性和说明或议论性的文章；而要求考生根据所给情景写出一篇约100词（标 点符号不计算在内）的应用性短文。 作为写作B部分的小作文总分10分，大家要抓住得分点。小作文在评分时有如下评分 要点：1.信息点——覆盖全面；2.内容——组织连贯；3.语言——准确性；4.格式——符 合要求；5.语域——恰当。 不出所料，今年英语二的小作文再次考查了书信体，并且考查的信件可以说是杂糅型的。这在2011年英语二中出现了同样的考查方式： Suppose your cousin LI MING has just been admited to a university write him/her a letter to： （1）Congratulate him/her，and （2）give him/her suggestions on how to get prepared for university life You should write about 100 words on ANSWER SHEET 2. DO not sign your own name at the end of the letter，Use zhangwei. 同样的考查方式，足以说明一件事情——绝对要重视考研真题。跨考教育英语教研室 的老师总在强调真题的重要性，希望大家以后一定要强化这种认识。 下面我们来详细解读下今年的小作文，首先看一下题目要求： 称呼： Dear Jack注意称呼中，后面的逗号不可丢，也不能写成冒号。 正文 建议大家三步走策略——简洁、直接、明了：写作目的、写作是由、重申目的第一段：写作内容需涵盖两点：写信目的，表明感谢来自朋友的祝贺；可以采用这样 的表达方式：I’m writing to express my gratitude for your congratulation on my success in the translation contest. 第二段：写作内容应以建议为主体。在这个过程中可以把日常我们如何提高的方式写 进正文，如讲究学习方式、注重坚持、多多接触外文文化及语境。那本篇老师主要从前两 个方面进行论述，表达如下：As regard to my experience, I would like to offer you some proposals in this part. At the top of list is the persistence due to the fact that you could deserve the position after days or years of efforts that you have had in the field. What’s more, you are supposed to pay more attention to the way in which you finish your major, for it plays a significant role in the process. 第三段：再次强调重申写信目的，如Thanks again and I do hope that my suggestions can be in favor of your future study. 落款： Yours sincerely, 特别提醒sincerely后面逗号不能丢；签名： Li Ming特别注 意 Ming 后面一定不能出现句点。
