说明文的语言特色,总的要求是准确、简洁、富有表现力。无论是事物说明还是事理说明,抑或是科学小品,都不能例外。准确、简洁,是说明文语言的最本质的特征。从说明文的主要功能来看,说明文主要是传播知识的。要使说明文传播的知识准确无误,就必须使用准确的语言冷静客观地解说事物,阐明事理,准确是说明文语言的先决条件;要使传播知识的说明文让读者一读就明白,说明文的语言就必须简洁。在此前提下,一篇具体的说明文,由于说明对象、读者对象和作者语言风格的不同,其语言特色可以平实见长,但有时也可以生动活泼。或概括,或具体;或简洁,或丰腴;或精练,详尽;或平易朴实,或幽默风趣,可根据具体的文章而定。
揣摩说明文的语言特色,可从这样几个方面人手:
①要有综合观念。揣摩说明文的语言特色不能置说明对象的特征,说明顺序和说明方法于不顾,要把这些内容综合起来看。
②抓住说明文语言准确性的本质特征,去理解文章中表时间、空间、数量、范围、程度、特征、性质、程序等词语。
③弄清什么是平实说明,什么是生动说明。
④认真分析文章所用到的各种说明方法,各种说明方法在文章中的`科学运用,正是说明文语言特色的正确体现。
⑤注意说明文中动词、数量词、修饰限制性词语的准确运用。
说明文是一种以说明为主要表达方式的文章体裁。它通过对实体事物科学的解说,对客观事物做出说明或对抽象整理的阐释,使人们对事物的形态、构造、性质、种类、成因、功能,关系或对事理的概念、特点、来源、演变、异同等科学地认识,从而获得有关的知识。

Dear Admission Committee:
Miss Pan Bei requested a letter of recommendation from me to support her application for graduate program at your university. As her teacher, I am pleased to comply with her request.
I first got to know Miss Pan when she enrolled at university and I was the assistant director of her class at that time. Being a professor for several years, I noticed that due to the lack of self-learning ability, it is really challenging for students, even those performing excellent in senior school, to keep up with the college speed. However, as a diligent girl without any solid background in Computer Science before college, she adapted quickly to the especially competitive environment in our department. At the end of the first year, she earned the 5th rank in her class, while ranking 1st among the girls. I was fairly impressed by her self-learning technique and exceptional efforts. Hence, I believe, goal-oriented, not afraid of inchoateness and with persistence, she has the quality to make achievements.
What distinguished her among her classmates, I think, was that she went far beyond acquiring excellent scores in the exams and instead got her range of knowledge enlarged. In spring, 2006, Miss Pan took the course I taught named Algebraic Structures and Combinatorial Mathematics. This inquisitive and assiduous young woman was sometimes the last to leave after my class, raising novel questions related to the subject. I found that she understood the knowledge in depth and detail. Furthermore, I still remember during the spring vocation in May, due to the break-down of my mail box, I missed her mails to discussing some questions. But the following week during the course time, she asked me directly. Her zeal for knowledge and the spirit to explore answers really leave me a deep impression. Finally, she was among the few students who got almost full marks in every test in class which showed her exceeding grasp of every chapter. Thus, I gave her 98/100 for the excellent performance in my course.
In summary, I have every reason to believe that Miss. Pan will make outstanding performance at your university as a graduate. I would appreciate greatly if you give her a favorable consideration. Please feel free to contact me directly if more assistance is needed. Faithfully yours,
Wanling Qu, Professor
Department of Computer Science and technology Peking University
