I was like that sp before my education began, only I had no way of ing how near the harbor was. The most important day I remember in all my life is the one on wch my teacher, Anne Mansfield Sullivan, came to me. I am filled with wonder when I consider the immeasurable contrast between the two lives wch it connects. It was the trd of March, 1, three months before I was seven years old. On the afternoon of that exciting day, I guessed vaguely from my mother’s signs and from the hurrying to and fro in the house that sometng unusual was about to happen, so I went to the door and waited on the steps. I felt approacng footsteps. I thought it was my mother and stretched out my hand. Someone took it, and then I was caught up and held close in the arms of the person who had come to reveal all tngs to me, and, more important than that, to love me. The morning after my teacher came she led me into her room and gave me a doll. When I had played with it a little wle, Miss Sullivan slowly spelled into my hand the word “d-o-l-l”. I was at once interested in ts finger play and tried to imitate it. When I finally succeeded in making the letters correctly I was filled with cldish pleasure and pride. Running downstairs to my mother I held up my hand and made the letters for doll. I did not that I was spelling a word or even that words existed; I simply made my fingers go in monkey-like imitation. In the days that followed I learned to spell in ts uncomprehending way many words, among them, “pin”, “hat”, “cup”, and a few verbs like “sit”, “stand” and “walk”, but my teacher had been with me several weeks before I understood that everytng has a name. One day wle I was playing with my new doll, Miss Sullivan gave me my old doll, too. She then spelled “d-o-l-l” and tried to make me understand that “d-o-l-l” applied to both. Earlier in the day, we had a struggle over the two words “m-u-g” is “mug” and “w-a-t-e-r” is “water” , but I persisted in mixing up the two. I became impatient and, seizing the new doll, I dashed it on the floor, breaking it into pieces. I was not sorry after my fit of temper. In the dark, still world, I had no strong sentiment for anytng. My teacher brought me my hat, and I knew we were going out into the warm sunsne. We walked down the path to the well-house. Someone was drawing water, and my teacher placed my hand under the spout. As the cool stream gushed over one hand, she spelled into the other word water, first slowly, then rapidly. I stood still; my whole attention was fixed upon the movements of her finger. Suddenly I seemed to remember sometng I had forgotten — a thrill of returning thought – and the mystery of language was revealed to me. I knew then that the “w-a-t-e-r” meant that wonderful cool sometng that was flowing over my hand. That living word awakened my soul and set it free. I left the well-house eager to learn. Everytng had a name and each name gave birth to a new thought. As we returned to the house, every object wch I touched seemed to be full of life. That was because I saw everytng with a strange, new sight that had come to me. On entering the door I remembered the doll I had broken. I felt my way to the fragments and tried in vain to put them together. Then my eyes were filled with tears, for I realized what I had done, and for the first time I felt sorry. I learned a lot of new words that day. It would have been difficult to find a happier cld than me when I lay in my small bed that night and thought of the joys that day had brought to me, and for the first time I longed for a new day to come.

急求英语说明文范文

How To Be Happy By Matt Farr At the airport bookstore, there are only about a dozen freestanding shelves of books. It's Darwinian selection at its most brutal: only the most popular authors, the newest novels, and the most recognizable classics survive. You won't find the lesser known works of Oscar Wilde or Voltaire or even Hemingway — there isn't space for them. Jane Austen makes only the briefest appearance, and Edgar Allen Poe shows his face only at Halloween. There are no collections of poetry beyond Dr. Seuss. There is, however, a whole rack of self help books. Americans are obsessed with making ourselves better. Smarter. Thinner. You can buy books to improve your vocabulary. You can devour a stack of books that will teach you to work more efficiently, more ruthlessly, and claw your way to the top — and then you can read books on how to stop and smell the roses and enjoy your life more fully. There are even books that will teach you how to organize your closets. All of these things dance around the essential truth: we want to be happy. We want to be loved. We want to find meaning in our lives and feel that our contributions make a difference. This, then, is the Rusty Brain Guide: How To Be Happy. Eat more cookies. Abstaining from a single cookie isn't going to make you look svelte and toned. Go on, eat some cookies. I recommend the double chocolate ones with chocolate chips inside. Sing. In your car. In elevators. At the mall, especially at Crate & Barrel and Pottery Barn. In hospital corridors. Before important client meetings. When people give you that patronizing look, wink at 'em. Make Popsicles. Stay home on the weekend and disconnect your phone. Bring a plastic straw to a fancy restaurant. Make loud gurgling sounds when you get to the bottom as you attempt to drink every last molecule of diet Coke. Order the stuff on the menu that you've never heard of — like Gkaeng Cheud Bplah Meuk Yad Sai (Stuffed Squid Soup with Napa Cabbage or Squash). Talk to strangers. Collect something weird that isn't expensive but is relatively hard-to-find. Wear odd hats in public places. Amass a jar of coins. Bury them in your back yard. Draw a treasure map and give it to a friend. Walk to the park near your house. Do some somersaults. When was the last time you did a somersault, anyway? Eat pickles out of the jar. Build a Web site and write your own Rusty Brain column (Matt only). Spend a day by yourself. Leave your cell phone at home. Wander the streets, muttering to yourself and occasionally disagreeing with what you've just muttered. Buy a puppy. Name it Charo. Get your teeth capped. Move to Hollywood. Become a star. (Isn't that what you've been dreaming about anyway?) Wear thong panties under your habit (nuns only). Throw a surprise birthday party for a friend. Invite lots of people. Make sure that your friend's actual birthday is nowhere near the date of the party. Belch in public. Then sigh contently. Suntan naked on a public beach. Adopt a European accent for the day to explain your complete lack of modesty. Quit your worthless job and dedicate your life to the study of the Moroccan flute. Fly a kite. Stop wasting your life with the Moroccan flute and get a real job. Volunteer at your library, or church, or your local soup kitchen, or Habitat for Humanity. Wear clothes so ratty that you are often mistaken for one of the needy. Use the word Jonesing as often as possible. As in, Man, I'm Jonesin' for some homemade Popsicles. Studies have shown this will make you happy. Join a bowling league. Buy a large red bowling ball. Name it Gorbachev. Drive to the nearest national forest. Hike a mile with a backpack full of cold fried chicken and biscuits. Find a clearing where you will not meet a single human and have a picnic. Stare at the clouds for a full afternoon and dream. Think about the things you love to do. Now go do those things more often. Meet someone, fall in love, live happily ever after.

英语的说明文怎么写？最好能提供一篇短小的范文~

我刚上四年级时，妈妈送给我一个精美的文具盒。

它那用铁皮做成的椭圆形外壳上，全被喷上了浅黄色的油漆，看上去像是被灯光照射下的微型舞台。

盒盖上的图案是穿着华丽衣服的美少女，一双炯炯有神的眼睛友好的望着我，好像在说：以后我们会成为形影不离的好朋友。

文具盒的背面画的是可爱的红精灵，漂亮极了。

打开文具盒的磁铁小开关，首先映入眼帘的是我的课程表。

在课程表的下面是一个黄色的“小窗帘”，打开“小窗帘”，嘿！我的小帮手们正在香甜地睡大觉呢！他们各自躺在自己的“小卧室”里。

你看，我的铅笔和钢笔躺在两张长形的“小床”里，谁都不碰谁；橡皮则住在一个正方形的“房子”里；我的“长条将军”格尺，正舒舒服服的躺在那张为它特制的“大床”里。

它们已经劳累了一天，就让它们好好的休息吧！ 别看我的文具盒平时一言不发，可到了关键时刻，它还挺热心的。

我把文具盒一打开，钢笔马上蹦出来，帮我把作业写得工工整整；当我动手画图时，尺子便会为我铺出一条笔直的线路，让我把线条画的又直又长；写错字时，橡皮又会自告奋勇，帮我擦掉错误…… 文具盒忠实地为我服务，是我学习上的朋友。

我非常喜欢我的文具盒。

2.我的铅笔盒 我有一个造型精致、功能齐全、美丽的塑料铅笔盒。

我的笔盒，前半部分是半圆形，后半部分是长方形。

的笔盖是浅蓝色的塑料做成的。

上面有个活泼可爱的小女孩儿拿着一只画笔正在画蓝天、白云和飞过的小鸟，还有一只摇头摆尾的顽皮小狗，似乎正对着小女孩曲曲的、水波荡漾的小河，河水清澈，哗啦啦地流向远方，草原上盛开着五颜六色的鲜花，有野菊花、有向阳花、有喇叭花，还有许多说不出名字的野花，随着轻风翩翩起舞，我也仿佛置身于美的旋律中。

笔盖中间还有着一个辛福的英语。

花的香气诱惑着漂亮的蝴蝶和金黄色的小蜜蜂，它们在花丛中跳跃着，摇摆着，好像一群小孩在追逐戏闹着。

我的笔盒盖是个多功能的盖子，它不但给以当盖子，还可以当尺子，前面还可以当量角器来用，打开正面笔盒盖，里面有一个透明的塑料小口袋，可以用来插课程表。

盒里有三个黑色的格子，细长的格子可以放尺子，短小的格子可放笔擦，还有一个最大的格子可以放各式各样的铅笔、钢笔和圆珠笔。

我的笔盒天天陪伴着我学习，它是我的好朋友，我喜欢它。

英语说明文怎么类比法写

如下：就“说明对象”而言，英语说明文可分为对“客观具体事物”的说明和对“主观抽象观念”的说明两大类。

对中学生来说，在汉语说明文的教学中似乎比较侧重前者，即解释客观具体事物的说明文。

但在英语说明文中，阐述和说明 “主观抽象观念”的说明文占了很大的比重，其中有些类似汉语中的议论文。

但是无论是对“客观具体事物”的说明还是对“主观抽象观念”的阐述，英语说明文从结构上看大致可分为三个部分：第一部分一般是文章的第一段，提出文章的主题，也就是说，文章想要阐述、说明的主要内容；第二部分是文章的主体，可由若干个段落组成，对文章的主题进行展开说明；第三部分是结尾段，对文章的主题作归纳总结。

从英语说明文的结构可以看出，要写好英语说明文的关键在于第二部分如何对文章主题进行展开说明。

【事理说明文范文】事理说明文范文生活中的文章,初中

人教版八年级上四单元写作指导 事理说明文写作指导 重庆市 邓大林 所谓“事理”，就是与事物有关的某种道理。

人们在生产、生活中，特别是在科学研究中，常常不满足于对事物表象的认识，而要进一步探究其中的原委，这就需要作事理的说明。

例如对立场、观点、名词概念、学术流派等进行说明，让人能领会其精神实质，从而憬然有悟，了然于胸，这样的说明文被称为事理说明文。

如何写好事理说明文呢？我们应当注意以下几点： 一、审准事理的说明对象 弄清说明对象，首先要弄清是写事物说明文还是事理说明文。

弄清说明对象可以从审题入手。

如《中国石拱桥》，从题目可以看出，它要介绍的对象是中国的石拱桥，并不需要我们阐明什么深刻道理，只需将它们的特点说明清楚即可，是事物说明文。

而《奇妙的克隆》从标题可以知道，文章必须给我们讲解清楚克隆技术的本质及克隆技术的发展和将带来的影响几个问题。

它向我们阐明的是一种事理，是事理说明文。

弄清说明对象的类别之后，就要就题立意──确定说明的中心。

确定说明的中心，要注意以下三点。

一是观点正确，具有科学性。

即我们解说的事物的本质及规律性要有科学根据，经得起实践的检验。

如课文《奇妙的克隆》中有这样的句子“可以这样说，关于克隆的设想，我国明代的大作家吴承恩已有精彩的描述——孙悟空经常在紧要关头拔一把猴毛变出一大群猴子，猴毛变猴就是克隆猴”，如果将这个例子作为我国明代就有克隆技术了，其说法肯定错误。

因为文学作品的想象事件是不能作为说明文的例证的。

二是说明深刻。

深刻是指说明事物要透过现象揭示本质，反映事物内部的规律性。

要使读者不仅了解事物“是这样的”，而且要明白“为什么是这样的”。

如《大自然的语言》，不仅要使读者了解大自然具有“物候”现象，而且应该了解为什么会出现物候现象，决定物候现象的因素有哪些，研究它有什么意义等深层次的问题。

三是抓住特征。

所谓特征，就是指事物所具有的独特的地方。

事理说明文必须抓住特征，突出中心。

说明事物表面上的特征，只能是读者对事物外部的特征获得印象；说明事物本质的特征才能是读者进一步获得比较深刻的认识。

二、掌握说明的逻辑顺序 事理说明文，按照事物内部的联系和人们认识事物的规律来安排材料，可以用逻辑顺序。

因为人们对客观世界的认识总是由整体到部分，由主要到次要，由浅入深，由简到繁，由具体到抽象，由现象到本质的，所以在写事理说明文时，我们必须将文章思路与人们对客观世界的认识过程保持一致，才能适应读者的接受能力和欣赏习惯。

如《大自然的语言》一文的结构顺序是：描述物候现象——做出科学解释——追究因果关系——阐述研究意义，这是按照从现象到本质的逻辑顺序组织全文的。

三、选择恰当的说明方法 和事物说明文一样，事理说明文也需要运用多种说明方法说明事物。

常用的说明方法有： 1.列数字。

用准确的数据说明事物的某些方面，这种方法叫列数字。

如：“仅在美国，每年由‘生物入侵者’造成的经济损失就高达两千多亿美元，面对这样的天文数字，人们岂能无动于衷？”（《生物入侵者》）这里的数据具体说明了“生物入侵者”造成的重大经济损失。

又如：“在189个这种换核卵细胞中，只有两个孵化出了鱼苗，而最终只有一条幼苗渡过难关，经过80多天培养后长成8厘米长的鲫鱼。

” （《奇妙的克隆》）这些数据准确说明了得到的囊胚细胞核的卵细胞在人工培养下大部分夭亡的情况。

2.举例子。

举出实例进行说明，使内容具体化，叫举例子。

《大自然的语言》第五段从反面举例子说明物候对于农业生产的重要性。

如1962年北京的物候比1961年迟10天左右，但农业生产仍是按往年的日期播种的，结果受到低温的损害。

3.分类别。

把被说明对象按一定的标准分成不同的类别，逐类加以说明，叫分类别。

如《大自然的语言》，在讲物候现象的来临决定于哪些因素时，就从纬度、经度、高下等方面进行分类说明。

4.作比较。

就是通过比较说明事物和事理。

例如《奇妙的克隆》中“克隆鲫鱼出世前后”的1、2段就对中外科学实验进行了比较，突出了中国科学家在克隆实验方面的研究成果和贡献。

5.作诠释。

用简明的语言指出被说明对象的本质特征，把那些容易与之相混的对象同它区别开来，叫做诠释。

如“凡是来至一个祖先的无性繁殖出的一群个体，也叫做‘克隆’。

”（《奇妙的克隆》） 6.打比方。

利用两种事物之间的相似之处作比较以突出事物之间的性状特点，增强说明的形象性和生动性的说明方法叫打比方。

如“可以这样比喻，板块背上驮着许多大陆，当板块向一个或另一个方向运动时，大陆也随之运动。

”（《恐龙无处不在》）运用打比方的说明方法，把深奥的科学道理说得生动形象，通俗易懂。

7.画图表。

有时，单用文字说明难以做到明确、具体，这时就可以用画图列表的方式加以补充，这种方法叫画图表。

8.引资料。

资料的范围很广，可以是经典著作，名家名言，公式定律，典故谚语等。

我们选择怎样的说明方法进行写作，这要根据自己的文章而定，因为运用说明方法的目的，是为了更...

说明文的说明方法的例子

说明文的结构 1、说明文的结构有：总分式、并列式、层进式、对照式（结构包括段落）。

一篇完整的说明文常常是几种结构综合运用的。

2、把握结构的意义。

说明的顺序 1、说明的顺序有：空间顺序、时间顺序（包括发展顺序）、事理顺序（逻辑顺序）等。

2、弄清顺序的意义。

说明的方法 1、说明的方法有：举例子、列数字、打比方、作比较、分类别、下定义（包括作解释）、引资料、列图表等等。

2、明白各种方法的作用。

3、有时说明文借用其他修辞手法来帮助说明，这些手法的作用分析应当紧紧围绕说明对象，依照说明文的要求。

说明文的语言 1、说明文语言的根本要求是科学性、准确性，简练明确；文学性说明文还要求生动性、形象性。

2、分析说明文语言的基本要求：首先是其对说明事物特征、性质的作用，其次是说明的严密性、科学性，第三是形象性、生动性。

解题思路和技巧 （一）明确说明对象：阅读事物说明文，不管是整篇还是整段，都要首先从整体人手，把握文章说明的是什么事物，即说明的对象是什么；阅潦吕硭得魑模？？？逦恼滤得髁耸裁词吕怼？ 如何找准说明对象呢？ 1、看题目，不少题目都表示说明的对象。

如（中国石拱桥）。

2、抓首括句和中心句。

好的说明文往往运用这种句子来突出所要说明的事物和特征。

（二）抓住事物特征：事物的特征主要表现在构造（内外），形态（大小、长短等），性质（硬、软、冷、热等），变化（动、静、快、慢），成因（简单、复杂），功用（广狭、正反）等等方面。

一般来说，说明文要说明的要点，往往就是事物的特征。

除说明的重点外，还要弄清作者介绍的是事物哪些方面的特征，又是从哪些角度介绍的。

例如《死海不死》一文，围绕死海的特征，从三个角度进行说明：先说死海的“死”（现象特征），再说死海的“不死”（本质特征），最后又说到死海的“不死”与“死”（现状与未来发展特征）。

这样死海的全面特征便被一层一层地揭示出来了。

又如《苏州园林》一文，围绕“无论站在哪一个点上，眼前总是一幅完美的图画”这一总特点，从五个方面加以说明：亭台轩榭的布局；假山池沼的配合；花草树木的映衬；近景远景的层次；以及门窗雕镂琢磨和颜色等。

这样从不同方面归纳分析，也就全面把握了苏州园林的特色。

（三）归纳说明方法：阅读说明文时，边读边标出文章所使用的说明方法，然后总结主要使用了哪些方法，并进而分析这些说明方法对准确说明事物特征所起的作用。

（四）逐段概括要点，理清说明顺序：概括要点时，要重视首括句、尾结句或提问式语句的作用，重视给概念下定义或解说的语句的作用。

阅读时可以把这些语句勾画出来。

概括要点时最好用完整的句子，意思要简明扼要。

在逐段概括要点的基础上，用“同类合并”的方法，把全文划分为相对独立的几部分，概括出每部分的大意，把每部分的大意依次连缀起来，就能比较清楚地显示出全文的说明顺序了。

使用什么说明顺序，还要看说明的对象。

一般来说，说明事物的演变发展的，用时间顺序；说明建筑物的，用空间顺序；介绍高科技产品或说明事物间的联系的，用逻辑顺序。

（五）整体感知，把握中心：在理清说明顺序的基础上，分析段与段、部分与部分之间的关系，就容易看出文章的基本结构了。

如是总—分式的结构还要着重分析“分”的部分是按什么原则组合的，是并列，是递进，还是包含有总分关系。

递进式结构要着重分析各层意思是怎样逐步深入展开的，是由现象到本质，还是由个别到一般，或是从结果到原因等等。

把握结构后，最好能画出结构示意图。

说明中心就是归纳出一篇说明文说明了被说明事物的怎样的特征，或阐释怎样的事理。

在理清说明顺序、把握文章结构的基础上，再归纳说明中心也就不难了。

（六）体会语言准确性：准确是说明语言的特点。

分析说明文语言，就是看遣词造句是怎样准确说明被说明事物的特征的。

要注意分析关键词语的作用。

如《向沙漠进军》一文中“沙漠是人类最顽强的自然敌人之一”中去掉“最”不足以说明沙漠危害之严重；去掉“自然”“敌人”性质就不清楚；去掉“之一”就绝对化了。

当然，文字的生动性也应充分注意。

如何写好高考英语说明文

要写好说明文应注意到以下几点：一、要善于抓住事物的特征介绍事物，一定要抓住事物的特征。

所为特征，就是这一事物区别与其他事物的标志。

只有抓住了事物的特征，才能将其状貌、性质、成因、功能和意义等说的明白、清楚。

任何事物都有其特征。

比方说，我们拿起一只铅笔，仔细地观察它，就会注意到它的颜色、形状、长度、锐利程度以及硬度等。

也许你的作文以“This pencil is of normal size and shape.”开头，接着你就描写这支铅笔所具有的与众不同的特点。

这种写作方法尤其适用于描写大家所熟悉的而又具有新的、与众不同的特征的事物。

再比如下面一段文字：“去年，妈妈从北京给带回一套西服，质地上乘，做工考究，可棒了。

”“质地上乘，做工考究”的服装很多，这几个字并未把这套西服的特征说清楚，因此不会给我们留下什么印象。

总之，介绍一件事物，要考虑从哪方面着手才可抓住事物的具有代表性的特征。

二、要遵循一定的顺序写任何文章都要做到条理分明。

介绍一件事物，目的是上让读者清楚地了解事物本身的特点、性质以及用途等，因此更需要条理清楚。

我们可以按以下三类顺序说明事物：1、时间顺序，即按事物的发生、发展的先后顺序进行说明。

2、空间顺序，即按事物空间位置的顺序，由上至下，由近及远或由里至外地进行说明。

3、逻辑顺序，即按人们认识事物的规律进行说明，如由概括到具体，由整体到部分，由现象到本质，由表及里，由原因到结果，由主要到次要，由特点到用途等。

总之，对于不同的说明对象，要按照不同的构造形体或发展规律作出不同安排。

三、选用恰当的方法 说明事物，我们常采用以下方法； 1、定义法。

定义法的目的是让不知此事物的人对此物有一个起码的了解，以利于下文的展开。

如：A thermometer is an instrument used for measuring temperature. 就是对thermometer下了一个定义。

有些事物也许不好下个明确定义，但我们可以交待这个事物的背景，来源，或列举出它的一些典型特征，以便让读者明白。

这类事物可以是术语，也可以是外国人所不了 的中国的传统事物，如龙舟节等。

2、举例说明法。

举出具有代表性的例子，能够真切地说明事物，化抽象为具体，使段落变得有血有肉，丰富起来。

举例时常用的表达有：for example（例如），for instance（例如），as an example of （作为……的例子），take… for example （以……为例）等。

3、比较法。

为了突出事物鲜明的特点，我们常把它与其他事物进行比较。

比方说我们想向读者介绍什么是“电脑”，我们可以说“It's a kind of electrical or artificial （人工的）brain.”这样把电脑和人脑进行了比较，从而使人们对“电脑”有更清晰的认识。

4、细节描述法。

介绍一种事物，仅用概述性的词语如beautiful, friendly, boring, good 或bad 是不够的。

作者要提供一些细节，使被描述的对象更加形象具体，从而加深读者的印象。

除上述几种方法外，我们还可以通过引经据典（即引用专家、名人等的话语）、列举数字等其他方法说明一件事物，从而使文章更加严密，内容更具有科学性，更有说服力。

四、运用恰当的语言介绍事物，文字要力求简洁、明白、准确。

比如：The cover of the magazine is very nice. 在此句中“nice”一词的意义不够明确，如果改用“artistic”就清楚了许多。

再如下句：We wish to state that this electric car was designed with the idea of safety in mind. 此句冗长，不够简洁，应改为：The electric car was designed for safety. 除讲究语言平实准确的前提下，我们还可以运用描写的方法，来增添文章的可读性。

例如在写题目为“My Pencil Box”这一文章时，若写成“I have a pencil-box, which was given to me by classmates as a birthday present. On it are three little bears. Inside are my pencils, a rubber and a pen-knife.”这样的表达是不是显得干巴巴的，毫无情趣？若能对三只小熊憨态可掬的形象加以描述，则会给读者留下深刻的印象。

另外，在介绍事物时，语言易流于单调，若插入传说、趣事，或引用诗文、成语，或运用比喻、拟人、反问等修辞手段则可使语言生动形象，引人入胜。
