“以情动情”是教育的共同规律。教师的情感对学生来说，是导体，是火种。教师首先要善于将自己对教材的感受及情感，体验传导给学生，让学生爱读说明文。俗话说：“树倒猴群散。”如果教师自己都厌教，那么，怎么谈得上学生“学海无涯乐作舟”呢？

这样的日子，匆匆的擦肩而过，然后渐渐的淡化为一滴水珠，淡化为一抹记忆。
夏天，那金黄的麦浪，可口的西瓜，安逸的假期已称为记忆的水珠，翻开一页新的篇章，似乎又将有无数的水珠涌入脑海，化为思绪奔涌的'河流。
最终，还是要去面对一切，敞开心扉，步入那个校园。
校园的早晨是安静的，空气中飘散着花草的清香，就像一位恬静的少女，披着万缕霞光，散发着独特的缕缕幽香。
这难道是这座人才辈出的学堂独有的香气？
天气依旧晴朗，天空清澈的如同湖水；晶莹得令人禁不住屏息凝神；蓝得安静，梦幻，还略带小心翼翼的缕缕幽香。
在这所学校中，生机是必不可少的，虽然学习繁重，但脸上荡漾的依然是笑脸。严肃的课堂中，银铃般的笑声时常从教室的窗口传出。
校园中，行走着。渐渐熟悉的景物一一从眼旁略过。夏末的树叶枝头，繁密依旧是一大关键词，显示出生机勃勃的样子。微风拂过，便奏起哗啦啦的抒情小调。
新学校伊始，初中的大门早已不留痕迹的打开，就像磁悬浮列车，“刷”的开过，只留下与铁轨摩擦发出的响声。
初中的生活渐渐的步入正轨。每天的时间总是跑的飞快，像一个苹果，每天咬一口，一个星期后，便留下一个核。其实，每一天的日子都要学会品尝，就像品尝丝滑的咖啡一般，让它缓缓地流入心底。这时，你会发现，生活，学习的日子，原来是如此的愉快。
印度的泰戈尔曾说：“只有经历地狱般的磨练，才能炼造出天堂的力量，只有流过的手指，才能弹出世间绝唱。“中学生活已经来临，需要用笑脸去面对。教室、宿舍、食堂，我不希望过着这样三点一线的生活，因为我本是一个清新开朗之人。我想——
捧起一本书，靠在窗边，静静地享受；
拿起一支笔，轻快地书写着字体，默默地汲取；
敞开心扉，面对大家畅所欲言，淡淡地滋润。
在这里，我想默默地告诫自己：不要因为自己不够优秀，不够完美，不够聪明，不够好。不要因为他们轻慢，他们驳斥，他们沉默，他们一笑而过。争锋对决的游戏，每天都在上演，而且亦是一天比一天完美。只要我足够坚硬，那么，我的对手，就足够软弱。

说明文是以说明为主要表达方式用来说明事物，阐明事理的`一种文体。它通过揭示概念来说明事物的特征、本质及其规律性，给人准确的科学知识或正确思想。一般可分为实体事物说明和抽象事物说明两大类，词典、教材、论文、实验报告、产品说明书、广告、解说词及科学小品等都属于说明文。
按写作方法,英语说明文主要分为下面六种类型
1.例证法 2.定义法 3.分类法 4.因果关系法 5.比较对照法 6.过程分析法
1.例证法
Our life today depends very much on energy. For example, machines have made our life easier than it used to be. The machines use energy, and energy is needed for heating, lighting, communications, carrying goods-everything. Factories use a great deal of energy to make the things that we use and buy and sell.
这段主要是讲能源问题。第一句为主题句,概括地说出"我们目前的生活很大程度上依赖能源"。接着用举例的方法从三方面说明能源的作用。
2.定义法
An ideal teacher must have the following characteristics. He should know his subject, but he can make mistakes if he is willing to learn. His personality is as important as his scholarship. An ideal teacher must be enthusiastic. He should be a bit of an actor and he shouldn't be afraid to show his feelings and express his likes and dislikes. An ideal teacher is one who grows, learns, and improves himself along with his students.
本段的展开是通过对"一个模范教师"下定义的方法,关键词"ideal teacher"在文中多次重复,能加深读者的印象。
3.分类法
As far as political views are concerned, people fall into three categories. First are the conservative people. Conservatives are opposed to sudden or great changes. Second are the liberal people. These people are in favour of progress and reform. But their opinions often seem too idealistic. Third are the moderate people. The moderates keep everything within reasonable limits. They are more practical in this hard world. In my opinion, most people seem to belong to this group.
本段把人按政治观点分为三类:保守派(conservative people、自由派(liberal people和温和派(moderate people,并对他们各自的特征进行了简要的分析。
4.因果关系法
Of the four seasons, I like spring best. I prefer spring because it is a season of much joy and gaiety. New life bursts out everywhere. Plants wear a green coat again and colourful flowers blossom in gardens and mountains. The old come outdoors for fresh air and the young plan for outdoor activities. Life becomes so energetic and happy.
第一句为本段主题句,末句是总结句。在主题句后, 作者用了四个句子阐述自己喜欢春天的理由。
5.比较对照法
I like having a twin sister. When she's happy, I'm happy. When she feels unhappy, I feel the same. Often, I know what she's going to say. Sometimes, I know what she's thinking. I like what she likes. I hate what she hates. We like the same music, the same food and the same books.
这段采用AB交错的比较方式,阐述孪生姐妹的相同特征。这种写法较流畅自然,给读者的印象也更鲜明突出。
6.过程分析法
There are several steps to plant a tree. First, dig a hole large enough for the tree, but the hole should not be too deep. Second, put the tree in the hole so that it is straight. Third, put the earth back into the hole again. Push it down hard with your foot several times. Finally, water the tree well, as often as possible.
这段分析了植树过程中的几个步骤。全段层次分明,连接词语(first, second, third, finally的使用加强了语句的连贯性。

Unfortunately, nowadays in many parts of the world lots of people fail to realize the importance of trees. They have cut trees down in large numbers without a plan, which makes the soil washed away. They don’t know where there are no trees, the rain washes away the surface of the soil and this causes floods.

学习用品作文说明文【四】
书是知识的海洋，书是绽纷的世界，书是知识的源泉……人类想出了许许多多赞美书的“美言”，来告诉我们书是多么重要。确实，书能带我们到异国他乡，领略各地风俗礼节，探索世界奥秘；书能让我们回到战争时代，战争的残酷与痛苦，提心吊胆的生活，风腥雨的日子；书还能把我们引进丰富多彩的童话世界，感受卖火柴的小女孩的辛酸，白雪公主的继母的恶毒心肠，尖酸刻薄，天鹅王子的.兄妹情深……我们所有无法理解，无法看见，无法知道的东西都能在书的字里行间中找到答案。
“用珠宝装饰自己，不如用知识充实自己。”书就像一本武功秘籍，每一本书是一种武功秘籍，看得越多，懂得就越多。“宇宙无边，知识无际”谁都能成为“天下第一”，只要你愿意下苦功，就一定会“开花结果”，有所收获。
学习并不是唯一的，多读书籍的确能学到不少课外知识。但全靠阅读书籍来学习还远远不够，要懂得学习方法。多读课外书固然是好，但是不是多看书就能在写作时一挥而就，出口成章呢？又不是爱读课外书就能成为“才子”呢？
“蜜蜂如果只在一处采蜜，所得的就非常有限。”写作只在看书上下功夫，收获也就不多，要写作水平提高就要多方面结合：在阅读课外书时，如果碰到四字成语或好词好句，必须马上记录在本子上，最好写上成语的意思和认为好的原因，在写作时就能派上用场了。协作有好词好句还不够，文章的协作次序和方法也颇为重要，这点就要看“老师评语”的栏目了。其实，要想写作文时胸有成竹，最好的方法还是要亲自动手多写，写完给父母或老师点评，然后修改，这样日复一日，总会有提高的作用的。
要写好文章的方法很多，我们未必能全想到，不仅自己可以多思考一些有用的方法，也可以多汲取别人的意见，让自己的知识面更宽广，更全面。
“缺少谦虚就是缺少见识。”要得到更多的知识，必须多方面收集，不耻下问是最快最好的方法。“谦虚为美德增色。”我认为，谦虚地向别人请教，只会有益而无害，能使自己的知识面越来越多源化，越丰富，而不会有损自己的尊严。不惜一切去追求知识的人不笨，有机会去追求知识而不愿意去请教别人的人才是真正的愚蠢！有时候，并不是自己去问别人就会回答你，“对于青少年，最关键的是从小要有好奇心，遇到问题要追问下去，这种精神比拿高分更重要。”而某些家长，把分数看得比一切都重要，而当孩子想父母解决问题的时候却丝毫也不理睬，这样只会让孩子越来越糟。
并不是求分数，学习是我们的权力，就算父母亲并不在乎，我们也不要放弃。“勤能补拙，熟能生巧”，一分辛苦一分才，读书就要相信自己。“不要等待运气的降临，应该去努力掌握知识，”不管遇到什么困难，我们都要坚信：“我能行，我一定能行！”

说明文的客观性很强，就是语言要求准确、简明和周密。教学中，教师只要抓住一些关键词句，让学生语言的准确性、分寸，同样可以激发起学生学习说明文的兴趣。再如，讲“石拱桥”特点时，“这种桥不但形式优美，而且结构坚固。”其中关联词表示出“形式”到“质地”的主次与递进的关系，不仅形体美，而且耐用，这足以说明石拱桥的好处了。讲“赵州桥”的特点之二时“大拱桥的两肩上，各有两个小拱”。让学生画出三幅大拱上有小拱的不同位置和数量的三座桥，进行比较，体会出说明语言的真正魅力。
此外，还可以让学生掌握一些富有趣味性的说明方法，引用古典神话典故，打比方，作比较等；让学生在写说明文中恰当运用一些叙述、描写、议论、抒情等表达方式；让学生在电化教学活动中参与；让学生自己质疑问难等等，着重培养学生客观准确的写实能力，进一步激发起学习说明文的兴趣。

一、 学围棋可以锻炼思维
围棋是围而相的游戏，每下一子就等于出动一兵向对方进攻，迫使对方设法应对，而对方下子也是在向你进攻，要求你设法打退他。这种不断进攻与防守的过程就是不断提出问题和解决问题的过程。在这个过程中，大脑得到不间断地锻炼，变得日益灵活、聪明。
二、 学围棋能培养能力很多小朋友对数字的加减乘除感到枯燥无味，而下围棋运用数字的机会很多，可以让你在娱乐中不知不觉地接纳数学，使计算能力得到锻炼和提高。围棋的竞争过程紧张激烈，双方斗智斗勇，能有效地培养高度的注意力、敏锐的观察力、细致的分析力、灵活的应变力、全局的统筹力，使你解决问题的能力大大提高。
三、 学围棋能陶冶性情、提高素质围棋对弈中要求棋手讲文明、懂礼貌、胜不骄、败不馁。对待生动活泼、战斗激烈、变化莫测的棋局，棋手只有发扬顽强拼搏的精神才能取得最后胜利。常下围棋的人，大多有临危不乱的镇定心态，谦虚、谨慎的美德，文明高雅的风度。
总之，学围棋能锻炼思维，培养能力，陶冶性情，提高素质。
