A Respectable Professor

      Not all lectures serve as utilitarian tools. You have to turn to the perfect series of lectures on quantum mechanics presented by Professor Su Rukeng to see a case in which the class plays an exclusively and purely academic role, providing you with motivation, inspiration and philosophy.
      With medium stature, thick spectacles and insightful eyes,not only does Professor Su possess the typical characteristics of a learned man, but he is also a genuine scholar, which is reflected in his classes distinctly.
     It is generally assumed that lectures on pure science delivered by a conventional scientist, usually indifferent and emotionless, are boring and extremely difficult in that the expression of such topics, if not sheerly descriptive, is inevitably and completely  mathematical  and  analytical  without  lively  pictures.However, that is not Mr. Su's style.
     On the contrary, ranked among the most enjoyable and comprehensible lecturers, Mr. Su is characterized by the encyclope dic knowledge, the appreciable and vivid physical picture visual
ization, the intuitive and profound philosophical ideas and the exceptionally attractive burnout.
      As a scientist engaged in the study of nature and the explanation of the universe, Mr. Su seriously believes in the harmony and simplicity, as the fundamental essences,  of the natural world, which compose the central motives of his ideology and are the real significance that we learn from him.
      As a consequence, Professor Su, together with his extraor dinary creativeness and imaginativeness, exerts a strong influence upon us and greatly encourages us to ponder on the essence of the universe and our lives.

简  评
    本文描写了作者的一个老师Professor Su。他的与众不同之处在于能把枯燥的纯理论课程讲得生动而有趣。作者首先描写了教授的外貌：medium stature，thick spectacles and insightful eyes，俨然是一个学者的形象；然后作者指出，与传统观念相反，Professor Su的课程能激发学生的灵感和求知欲。作者有一段这样的描写：Mr．Su is characterized by the encyclopedic knowledge，the appreciable and vivid physical picture visualization，the intuitive and profound philosophical ideas and the exceptionally attractive humour，几个并列的词组勾勒出教授的博学和风格。最后，作者提到了教授对自己的影响：激励自己思索宇宙和人生的真谛。 （转载自http://www.ＮＳＥＡＣ.com中国科教评价网）
    文章词汇丰富、用词准确，但不足之处是作者过分依赖长句。全文只有一个短句：However，that is not Mr．Su's style．一般来说，短句铿锵有力，适合用来突出或强调所表达的观点；长句适合表达较为复杂的观点或内容，描述性或理论性的内容。如果一个
段落或一篇文章全是简单句，会使所表达的内容缺乏连贯性和完整性；而长句过多则显得重点不突出，拖沓冗长，也增加了理解上的难度。因此要合理地交替使用长短句：如在使用一系列长句以表达复杂的思想和画面之后，用一个短句收尾，能产生一种新鲜和扣人心弦的效果；或在一系列短句之后使用一个长句，能让读者有一种圆满的感觉。
    此外，作者还用了很多插入成分，使句子不够流畅。插入成分太多，容易出现主谓不一致的情况。
