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 eceptionally 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。
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．sus 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。
