李明是学化学的，性格开朗幽默，颇有魅力，但英语成绩不佳，每次只能勉强及格。老师警告他，英语不好会阻碍他拿奖学金，并亮出了自己的王牌：如果李明不努力，就让他考试不过关。老师还告诉他，学习英语不能只为了文凭，否则他即使大学毕业，也还是个半文盲。李明虽然保持镇定，但他明白，他的学业生涯正在攸关之际，必须安心下来埋头学习，坚持不懈。
Li Ming was a chemistry major, a charmer noted for his easygoing and humorous temperament. However, his English was so poor that he always barely got by.

（二）出国留学热
早在100年前，出国留学就被视为一种强国之策。直至今日，越来越多的学生热衷于出国留学。但当下风行的留学热，掺杂着一定的盲目性和随意性，从而导致很多问题的发生，如许多留学生花掉家中积蓄，搭上个人青春，到头来却是半途而废，有的甚至成为恶习缠身的“问题学生。”最好不要盲目地跟随当前的这股出国留学热，选择适合自己的发展方向才是最重要的，因为“三百六十行，行行出状元”。

（三）食品供应商缺乏诚信已经成为当今社会的一大问题。部分企业欺骗公众，故意散布假消息，颂扬食品添加剂是食品工业的伟大成就，并声称适量的添加剂对健康有益无害。部分有良知的科学家对食品添加剂的含量和毒性展开了深入的病理学研究。研究结果表明，部分常见的食品添加剂经长期，可能会对健康产生危害，这被认为是食品安全研究方面极为重要的一项成就。

（四）
在现代社会，尽管社会进步，物质丰富，人们总感到有些地方不对劲，但却又难以明确指出到底问题出在哪儿。空虚，没有归属感，缺乏稳定的社会关系似乎都成为人们略感不快的来由。人们对于快乐这个棘手的话题，似乎都有共识：若问及人们生活怎样，他们会谈及他们的家人、工作等而非仅仅是回答他们的薪水多少。对他们而言，生活的质量比薪水的数量更加重要。而政治家们却对此难以理解，为这些难以测量的家庭价值观念而感到困惑。实际上，政府可以发挥积极地作用来响应人们对于快乐幸福的渴望。最终，整个社会的幸福需要我们大家共同参与，确实，参与本身就能带来快乐。
In modern societies, despite the social progress and prosperity. People always feel that there is something not quite right. However , it is hard for them to put a finger on it. A feeling of emptiness and not belonging, a lack of defined solid relationship em to be the sources of unhappiness. People all agree on the great conundrum of personal happiness: when asked how they are, they will answer in terms of their family life and work life rather than just what they are paid. For them, the quality of life means more than the quantity of salary.
However, politicians find it hard to grasp the subject, and are flummoxed by immeasurable concepts such as the family value. As a matter of fact, the government can take a provocative role to respond to the yearning for happiness. Ultimately society’s happiness requires us all to play our part, and indeed, playing our part is part of being happy.
