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

11月3日，学校组织全校的同学们进行了一次秋游活动——到龙腾素质教育基地接受训练。虽然天气不是很好，但同学们一个个都精神抖擞、喜笑颜开的，个个的心情大概和我一样迫不及待吧！终于大家怀着激动、愉快的心情乘坐这着大客车前往素质教育基地，一路上，留下了同学们的欢声笑语。
“到了！”同学们喊着。我们马上放眼望去，六个醒目的大字“龙腾素质教育基地”在迎接着我们。我们跟随着教官走近基地，基地很大，教官带领我们做完热身运动后，来到了“智勇攀岩”的场地。只见一个像山峰岩壁的东西，双手抓住边上的布带子往上爬，只要爬到顶端，就算攀岩成功了。我一看要爬这么高呀，万一没准稳摔下来怎么办啊？正当我犹豫时轮到我了。我只好在那磨磨蹭蹭的，可不敢往上爬。这时教官好像看出了我的胆小，对我说：“男子汉要勇敢些，别怕，有我在的嘛！”听了教官的话，我鼓起勇气，大胆的往上爬，终于爬到了顶部。我突然觉得自己长大了，心里的胆怯也一下子消失了，我成了一个勇敢的男子汉了！
接下来我们又玩了飞夺泸定桥等项目，可是快乐的时光总是这么短暂。活动结束了，我们带着疲惫、带着收获，依依不舍的离开了龙腾基地，离开了这个带给我们喜悦和欢声笑语的地方。

一放假，妈妈便兴致勃勃地向我介绍环球中心，并同意我去那里玩一天。从妈妈的介绍中我知道了环球中心中有：65米高的天梯、真冰滑冰场和天堂岛海洋乐园。
一进门我们便看到了超高的天梯，我们上了天梯，越来越高，我也越来越害怕，终于到了四楼，再向左一转便来到了滑冰场。
这个滑冰场可真是气派呀!放着动听的乐曲，五颜六色的滑冰鞋在冰上划出一条条优美的弧线，仿佛连冰也成了彩色的了。我迫不及待地冲进滑冰场，换好了装备，做完了热身便进入了滑冰的场地。
我已进去便差点滑了一跤，然后我又扶着墙站了起来，我又向前一滑，发现滑冰其实也没什么好难的，只需要保持平衡向前滑就可以了，然后我重心向下慢慢地向前滑了起来，滑完了几圈后我认为我已经很不错了便到了滑冰场的中间——没有墙可以扶的地方，可能是心态缘故吧，我既然觉得中间比外面好滑，所以我便在中间滑了起来，突然我“咚”一声摔了一跤，好好一看才发现这里的冰太硬了，摩擦力太小了，所以这里很容易摔倒。后来我越滑越熟练，滑冰真是太好玩了!
后来因为种种原因我没去天堂岛海洋乐园，不过我和妈妈大吃了一顿牛排，正好弥补了这个遗憾。
环球中心真是太好玩了，不久又要开放新的娱乐项目了，想知道是什么吗?那么环球中心见!

星期四的早晨，我早早地来到了学校，因为我们要去新都的龙腾基地学习和玩耍。老师对我们说：“你们一定要听教官的话，如果走丢了，那就打电话给学校的老师。”话音刚落，就听到广播的声音：“请各班到操场集合。”到了操场上，只见前方几个身穿迷彩服的人站在那里，经过老师的介绍，才知道他们是这次活动中的教官。我们班的教官姓张，张教官对我们提出几个要求，就带领我们上车了。一个小时后，我们终于来到了龙腾基地。
我们班玩的第一个项目是冲破腊子桥，有几个胆小鬼，上去了就下来了，多亏了张教官的帮助，他们才能下来。第二个是走小木桥，张教官说：“你们除了要走这个小木桥，还要数它是由多少块木板子组成的。”我数的是八十七块，还好说对了，免受处罚。而那些数错了的人，就被罚做了10个下蹲了。第三个是空中飞人，我一坐上去，人还没反应过来，就立刻滑了下去，真想再来一次，可是没有机会了，还是等下次再来体会吧!第四个是烟雾逃生演练。这可是我的强项哦!当烟雾袭来时，我的脚底像抹了一层油似的，一下就跑到了安全地带。可是，有些人就没那么幸运了，他们被浓烟呛得不停咳嗽。
后来，我们还进行了挖紫薯比赛。可这次我就那么幸运了。挖了半天，我只挖了两棵拇指般大的迷你小紫薯。看着人家脸上挂着喜悦的笑容满载而归，我只有羡慕的份儿了。哎，下次一定要动作麻利点。
愉快的一天结束了，我怀着无比留恋的心情踏上了回家的路途。
再见了——龙腾基地。
