篇5:2024初中生写作指导:怎样写说明文

全文共 4396 字

+ 加入清单

一、要抓住事物的特征

一篇说明文写得好不好,主要看它有没有抓住事物的特征,写出来是不是使读者得到具体而明确的认识。比如,你参观了动物园,要向小读者介绍长颈鹿。什么是长颈鹿的主要特征呢?跑得快,斑纹美丽,这些都不是长颈鹿独具的特点。长颈鹿最主要的特征是脖子长,它是世界上最高的动物,母鹿身高四米多,公鹿五米左右,最高的记录是五米七八。它有四条又细又长的腿,还长着一个特别长的脖子。令人惊奇的是,它的颈椎骨只有七块,数目和人的颈椎骨一样。长颈鹿的七块颈椎骨排起来,就是它的长脖子,每块颈椎骨的长度就可想而知了。只有把这些写清楚,才算抓住了长颈鹿的主要特征,称得上是一篇较好的说明文。否则,你就说不明白。

那么,怎样去抓特征呢?

首先,要细致观察。文章是客观事物的反映,只有深入细致观察,才能对事物了解得清楚。河南郑州市七中刘伟同学写了一篇介绍《粉蝶》的说明文,文中对粉蝶的种类、形态、生活习性,粉蝶为什么不能在清晨飞舞,以及它对农作物有哪些危害等等,都写得清清楚楚,有根有据。这篇说明文曾被一些学校选为教材。刘伟同学为什么能写出这样好的文章呢?这是因为他平时时生物就有浓厚的兴趣,并且能亲自实践,仔细观察。两年里,他制作了四百多个标本,光粉蝶标本就制了三百多个,共有五、六个种类。他在谈体会时写道:

“昆虫的个体很小,特别是头部构造很难观察。我就向老师借了一个放大镜,我观察的东西就广泛了,昆虫中有粉蝶、蜜蜂、蝗虫、蜻蜓、蚊子、苍蝇等等;植物叶子中有柳叶、梧桐叶、榆叶、槐叶等等,还有草叶和花木……我常把放大镜、笔、记录本带在身边,上下学路上,去公园游玩时抽空作些观察,并记下主要观察内容。”

其次,要查阅资料。我们不能事事亲身经历,而说明文又要求特征准确,材料翔实,这就需要查阅有关的资料,靠前人总结出来的经验来印证。比如,有个在长沙读书的中学生,到北京旅游,参观了故宫,很想向同学们进行介绍。于是,他不但记下了参观的印象,还买了一张《故宫旅游图》和一本《北京十大名胜》,从中了解故宫的历史、地理位置和建筑特点。这样,他就知道:“故宫又名紫禁城,是我国明朝和清朝两代的皇宫,有五百多年的历史。整个宫城呈长方形,占地七十二万平方米,有大小宫殿七十多座、房屋九千多间。周围环绕着十多米高的城墙,墙外是五十多米宽的护城河。城墙的四角上,各有一个玲珑奇巧的角楼。故宫建筑群规模宏大,布局统一。我国明朝初年,为了修建这座宫城,曾经‘役使十万工匠和百万夫役。’故宫是我国古代劳动人民血汗和智慧的结晶。”上面说的这些具体数字、建筑特点,不查阅必要的资料,自然很难掌握。

最后,还要学会比较。世界上的事物千差万别,不同的事物有不同的特点,即使是一类事物,也各具特征。世界上没有绝对相同的两片树叶。孪生兄弟,长得再相似,也能区别出来。抓住事物的特征,就是抓住这个事物区别于其他事物的不同特点,从共性中发现个性,从一般中找到特殊。事物的特征往往在同别的事物相比较中显示出来。比如,要说明中国是一个大国,这个“大”字就很有学问。你可以直接说,中国的面积有九百六十万平方公里,也可以用比较的方法来说明。中国的面积,与法国比,有十七个法国大;与日本比,有二十五个日本大;与英国比,有三十九个英国大;我们祖国的面积,相当于整个欧洲。这样一比较,既具体,又生动,很有说服力。

总之,要抓住说明对象的特征,一方面靠亲身实践,细致观察,另一方面又要善于向书本和有经验的人学习,同时还要周密思考。学会比较,努力去熟悉所要说明的事物。

二、说明要有条理

要想写好一篇说明文,除了要抓住事物的特征外,还要掌握事物本身的条理。依据事物本身的条理来说明,就是要从复杂情况中理出头绪,把事物的特征,事物各部分的关系说清楚,所谓说明有条理,就是行文线索要清楚,层次要分明,不能想到哪里,写到哪里。如果颠来倒去地写,文章的头绪紊乱,同样也会说不明,道不白。叶圣陶先生写过一篇《景泰蓝的制作》的说明文,十分注意文章的条理性。作者抓住“做胎”“掐丝”、“涂色”、“烧制”、“打磨”五道关键的工序,对每道工序的制作和原理都做了详细的说明。结构严紧,条理清楚。

说明文有两种,一种是说明具体事物,如介绍一种新品种;一种是说明抽象事物,如“什么是世界?”。但是无论是具体事物还是抽象事物,都有其特征,都有它的构造和结构,只要我们遵循事物的规律,按照一定顺序加以说明,条理也就清楚了。

说明具体事物的文章,可以由上到下,由前到后,由外到内,由主到次地写,使读者容易了解各部分的相互关系。例如,你们学过的《第比利斯地下印刷所》一文,作者茅盾是这样介绍这个普通小院的结构的:

“这个院子跟附近的许多院子没有什么差别,周围是半人高的木栅栏;左边是一间独立的小屋,屋里有一口井;右边是两间正屋,每间大约一丈见方,前面有走廊;正屋的下面是个地下室,半截露在地面,是做厨房用的,从一边小梯子走下去。

——这样一个院子,在当年是第比利斯小市民住宅的标准样式。

读了这段文章,我们对这个地下印刷所的方位、构造和样式一目了然,就是因为作者按照这样的顺序来说明——由外到内,由左到右,由上到下。

有的同学在介绍具体事物的时候,没有事先根据这些事物的相互关系理清脉络,归纳分类,结果往往容易出现关系凌乱、层次不清的毛病。例如,有一篇介绍商品的文章是这样写的:

“青年食品商店出售各种罐头、干果、香烟和名酒。有菠萝罐头、桔子罐头!荔枝干,有中华牌香烟、牡丹牌香烟、前门牌香烟;有桂元干、葡萄干,有汾酒、竹叶青,还有清蒸元鱼罐头以及闻名世界的茅台酒等等,花色多样,品种齐全。”

这段话中所列举的商品,既有种概念,又有属概念,既有并列的关系,又有从属的关系。作者没有按照这些商品之间的内在关系归纳说明,而是想到哪里写到哪里,层次不清,条理不明。这段话应该改为:

“青年食品商店出售各种罐头、干果、香烟和名酒。罐头有菠萝罐头、桔子罐头、清蒸元鱼罐头等;干果有桂元干、葡萄干、荔枝干等、香烟有中华牌、牡丹牌、前门牌等;名酒有茅台酒、汾酒、竹叶青等。花色多样,品种齐全。”

说明抽象事物的文章,不但要说明事物是“这样的”,而且要进一步说明“为什么会这样的。”这就要按照人们认识事物的规律,步步深入地加以说明,或由浅入深,或由表及里,或由具体到抽象,或由原因到结果,或由现象到本质,或由数量到质量,或由特殊到一般等等。例如,鸟为什么会飞?人为什么会做梦?都属于这一类。如果是说明事物的变化发展过程,可以按照时间的顺序。如果属于介绍生产技术,可以按照生产的程序。只有按照事物本身的条理,来确定说明的顺序,文章才能写得眉目清楚。

当你读完这篇文章以后,请你不妨做做这样的练习:

假如你有一位在北京上学的朋友,暑假里,他想到韶山参观毛主席的故居(你住在韶山附近),希望你陪他一起参观。但是,他不知道怎么走最方便,怎样才能顺利地找到你家。那么,请你写封信告诉他:你家的地址,从北京到长沙应该坐几次车,到了长沙,又怎样才能找到你的家,你家的四周有些什么可供辨认的特点和标志。要求使你的朋友看了你的信以后,在路上不必多打听就能顺利地找到你家。

三、说明文的语言要确切、简洁、通俗

确切:说明文内容的科学性和专业性都比较强,它要求语言要确切,不能夸大和缩小。比如,有个同学知道他们学校种了很多树,绿化搞得不错,他在《我们的校园》一文中写道:“我们学校的绿化面积在全市中学居首位。”这样写就有不够准确的地方。如果有人问:“贵校的绿化面积到底有多少?你怎么知道别的学校都不如贵校呢?”这位同学恐怕就不好回答,因为他只知道本校绿化搞得好,还来不及进行一番仔细的调查研究。所以,这句话可以改为:“目前,我校的绿化是全市绿化搞得好的学校之一。”加上“目前”二字,不包括“过去”和“未来”;加上“之一”,就不是“唯一”。这样就比较确切了。

语言确切,首先是用词准确。说明文最忌含糊其词,什么“大概”、“差不多”、“可能”……模棱两可,该肯定不肯定,该否定不否定,用来说明事物就不容易做到恰如其分。《中国石拱桥》一文中有这样一段话:“赵州桥横跨在洨河上……修建于公元六○五年左右,到现在已经一千三百多年了,还保持着原来的雄姿……赵州桥非常雄伟,全长五十点八二米,两端宽约九点六米,中部略窄,宽约九米。”

这段话中的数字,有的是约数,有的是确数。因为赵州桥在哪年建成,史书上已经找不到确凿的记载,所以只能说个约数;而赵州桥的长度,却精确到小数点后两位,这不但要说明实有其桥,而且从这些具体精确的数字,可以看出我国古代劳动人民的智慧。写说明文,一定要下功夫选取“最恰当的”、“最精确的”语言来表达。

简洁:语言简洁,就是精炼,干净利落,用尽可能少的话,把事物说清楚,不要罗嗦重复、拖泥带水。比如“大雪把铁路淹没无踪”,“下水游泳应注意些什么”,这两句话中的“无踪”和“下水”都是重复多余的话,应该删去。

为了做到说明文的语言简洁,还要防止不必要的“引伸”和“寓义”。有些同学习惯于写记叙文,喜欢形容和描写,初学写说明文,有时也要来一番“引伸”和“寓义”。比如,有一篇介绍《松树和柳树》的说明文,结尾是这样写的:

“我们既要学习松树坚强不屈的品格,又要学习柳树栽在哪里,就在哪里生根的精神。”

记事抒情的文章,自然可以这样写,说明文就没有必要了,写了反而“画蛇添足”,不简洁了。

通俗:语言通俗,就是运用群众中明白通顺的话,把本来是抽象的概念说得具体生动,把本来深奥的道理说得浅显易懂。下面,让我们看看这段说明:

几千年来,劳动人民注意了草木荣枯,候鸟去来等自然现象同气候的关系,据以安排农事。杏花开了,就好象大自然在传语要赶快耕地;桃花开了,又好象在暗示要赶快种谷子,布谷鸟开始唱歌,劳动人民懂得它在唱什么:“阿公阿婆,割麦插木。”这样看来,花香鸟语,草长莺飞,都是大自然的语言。

这些自然现象,我们古代劳动人民称它为物候。

以上一例,是关于什么是物候的说明。作者使用的语言通俗,说明具体而生动。它把气候变化和动物活动、植物生长、农业生产的关系都说清楚了。

说明文的语言要通俗,并不是不要生动、有趣。叶圣陶先生在《文章例话》中说:“说明文不一定就是板起面孔来说话,说明文未尝不可带一点风趣。”有些说明文运用拟人、比喻、引用等修辞手法,写得很有趣昧。例如:

(1)庄稼有了化学朋友,就不怕生物界敌人的进攻了。

(2)蜻蜓被誉为昆虫里的“飞行之王”。在闷热的夏季,暴雨将至或骤雨初歇,蜻蜓常常三五成群在空中飞舞。它好似一架飞机,而飞行技巧却远远高超于飞机之上。

(3)“白露早,寒露迟,秋分种麦正当时。”这是华北中部地区流行的一句农谚。这句农谚说明种庄稼要看节气。

例①运用拟人写法,读来颇有情趣。例②把蜻蜓和飞机相比,贴切生动,使被说明的事物变得浅显易懂。例③引用农谚,通俗地讲解了节气与种庄稼的关系。

Consumers often found themselves being blackmailed by those merchants selling

shoddy products; and there are students

Cheating in order to pass the exams or get high marks; moreover, we are not

short of examples that many rich professionals evade the taxes by sacrificing

the interests of government.

But havent we seen their results? "A fall into the pit, a gain in

范文:

With the general standard of living improvingand the working week becoming shorter,more andmore people are able to make a holiday trip toplaces of interest. While many like to joinpackage tours fro convenience,I prefer to traveln my own.

I like travelling on may own not only because it costs much less but because it gives a great degree of independence and freedom. Travelling on my own,I’m my own boss;and can decide when to start on my way,where to linger a little longer and which spot can be skipped over to save energy or time for another spot. I can always adjust my plan. On the contrary,in a package tour you’re deprived of as much freedom as in a military base. At the sound of the whistle,you have to jump up from a sound sleep and,with heavy-lidded eyes,hurry to the gathering place where you are collected and counted to board a coach. At the sight of the little flag waving,you must immediately take yourself away from the scenes you are marveling at and follow the guide whose sole interest is to cover all spots according to him strict schedule,regardless of the weather or your health condition.

True,you may encounter inconveniences if you travel individually,for instance,getting accommodations for the night and finding a place for meals. But nothing can be compared with the freedom which is vital to a person who takes a holiday trip mainly to escape from constraints of his routine life.
