说明文有很高的科学性。它要求在说明事物时,力求正确,不夸大,不缩小,按照事物的本来面目进行反映,要实事求是,不粗枝大叶,凭想当然,瞎说一通。说明文的科学性主要体现在以下两点:
(1抓住事物的特征进行说明。事物都带有特殊性。而这种特殊的矛盾,就构成一事物区别于他事物的特殊的本领。说明文抓住事物的特殊性进行说明,才能使读者从文章里充分地、正确地了解所说明的事物;事物的特征不清楚,说得模模糊糊,就容易和其他事物相混淆。只有抓住事物的特征去说明,才能给人留下清晰的印象。
(2说明的内容要正确。即对一些尚未定论、有待研究的事物,不要轻易下绝对肯定或绝对否定的结论。要知道,读者阅读说明文是为了增长知识,如果把那种缺乏科学性的"知识"传给了读者,就会带来不良的影响。如有两家报纸,分别发表文章,谈酸菜对人体的作用,说法却完全相反。一篇文章认为,酸菜具有良好的营养价值,同时,还是良好的饿药物,可以治疗慢性并,因此主张人们多吃酸菜。另一篇文章则认为,酸菜内喊有大量的白地霉菌和亚硝酸盐,这是一种致癌物质,会直接引起肝癌、胃癌和食道癌等疾病,危害人体健康。因此,希望人们不吃酸菜。究竟是多吃酸菜好事实不吃酸菜好呢?这叫人无所适从。实际上,据有关专家分析,这两篇说明文都有一定的道理,但都有片面性,缺乏科学性。而这两篇文章的作者都忽视了这个问题,断定酸菜只有"好处"或只有"害处"是不对的。

与开头一样,文章的结尾也是相当重要的。成功的结尾,能使读者更深入、更透彻地理解文章内容,进一步领会文章的.中心思想;精彩的结尾,能唤起读者的思考与共鸣,增强文章的感染力。选择结尾的方法,也必须从全局来考虑,要使记叙的事件完整清楚,使文章的结构首尾呼应,以求得更好地表达中心,达到写作的目的。下面介绍几种常用的结尾方法。
(1)自然结束法在把内容表达完了之后,自然而然地收束全文,而不去设计蕴意深刻的哲理语句,这样的结尾谓之"自然结束法"。它完全避免了文章画蛇添足、无病***的结尾毛病,显得单纯明快、朴素无华。但讲究"自然"并不意味着随心所欲,马虎草率,而是顺着文思发展的自然趋势结束全局。
(2)画龙点睛法
这种结尾方式,就是在文章结束时,以全文的内容为依托,运用简洁的语言,把主题思想明确地表达出来,或者在全文即将煞尾时,把写作意旨交待清楚,所以这种结尾方法又称"卒章显志法"。如《枣核》结尾写道:"改了国籍,不等于就改了民族感情,而且没有一个民族像我们这么依恋故土的。"《记一辆纺车》结尾写道:"跟困难作斗争,其乐无穷。--记一辆纺车。"
有时,用来总结全文的还可以是名言、警句或诗句,这样的结尾更是言简意赅,起到画龙点睛的作用。如《驿路梨花》的末段"我望着这群充满朝气的哈尼小姑娘和那洁白的梨花,不由得想起了一句话'驿路梨花处处开'。"
(3)抒情议论法
用抒情议论的方式收束文章,能够表达作者心中的情绪,激起读者情感的波澜,引起读者的共鸣,有着强烈的艺术感染力。抒情议论式结尾的形式是多种多样的,所以采取这种方式结尾比较自由,好的"抒情议论"式结尾必然油然而生真情,给读者以真实感、充足感。如《回忆我的母亲》结尾的两个自然段就是很典型的抒情议论式的结尾。鲁迅先生的《故乡》的结尾是最典型的例子:"我想:希望是本无所谓有,无所谓无的。这正如地上的路;其实地上本没有路,走的人多了,也便成了路。"这段议论含蓄、深刻,一语双关。启发人们为创造新生活勇敢地开辟道路,使全文的思想感情得到升华。
(4)首尾呼应法
结尾与开头要相呼应,写出既呼应开头,又不简单重复的语句,这种结尾方式是各类文章极常见的收束方法。这种收束方法能唤起读者心理上的美感,产生一种首尾呼应,浑然一体的感觉。如《一件珍贵的衬衫》,开头写了"在我的家里,珍藏着一种白色的确凉衬衫。"结尾写道:"四年来,这件珍贵的衬衫,我精心地收藏着,没有舍得穿它一次。"前文提到的《谁是最可爱的人》的结尾,也是与文章的开头遥相呼应的。不仅又一次回答了文首提出的"谁是我们最可爱的人呢?"这个问题,而且抒发了强烈的感情,增添了文章的感染力。
(5委婉含蓄,点化主题。有些记叙文的结尾,同时要提示读者注意了解文章的主题,但是作者不是用逻辑思维的方式和直截了当的语言告诉读者,而是用比喻、象征等形象化的方式暗示给读者。例如,杨朔的《荔枝蜜》就是如此:这黑夜,我做了奇怪的梦,梦见自己变成一只小蜜蜂。这里所说的"梦",就是一个有象征意义的形象。常言道:日有所思,夜有所梦。人们可以通过某人的"所梦",推断他的"所思"。因此,读者从这个梦里,可以了解到作者十分赞赏、推崇蜜蜂那种"对人无所求,给人的却是极好的东西"、"渺小""却又多么高尚"的品质,并且愿意身体力行,向蜜蜂学习的愿望。而这正是作者所要表现的主题。不过,它不由作者直截了当地说出来的,而是经过作者的"点化",读者领悟到的。
(6)以人物描写或景物描写结尾。如《花市》结尾写:"她笑微微地站在百花丛中,也像一枝花,像一枝挺秀淡雅的兰花吧。"作者用"一枝挺秀淡雅的兰花"比喻姑娘美好的心灵。
"良好的开端是成功的一半",一篇文章的开头是很重要的。文章有了好的开头,不仅能带动全篇,使文章顺利展开,而且能抓住读者,引人入胜。这里,向大家介绍几种记叙文常见的开头方法:
(1)交代事件基本要素的叙述法
《挥手之间》的开头,交代了事件的时间、地点:"一九四五年八月二十八
日清早,从青凉山望下去,见有不少人顺着山上大路朝东门外飞机场走去。"
(2)开门见山、揭示主题的点题法
《背影》一文的开头写到:"我与父亲不相见已二年多了,我最不能忘记的是他的背影。"《白杨礼赞》一文开头就说:"白杨树实在是不平凡的,我赞美白杨树。"这样的开头简洁明快,直截了当,读了开头,能立刻抓住文章的中心。
(3)环境描写、渲染气氛的描写法
《驿路梨花》的开头描写了自然环境:"山,好大的山啊!起伏的青色群山一座挨一座,延伸到远方,消失在迷茫的春色中。"渲染了哀牢山中深远迷茫的气氛,对后文写边疆军民助人为乐的感人事迹起了反面衬托的作用。
《多收了三五斗》描写的是社会环境:"万盛米行的河埠头,横七竖八停泊着乡村里出来的敞口船。船里满载的是新米;把船身压得很低,齐着船舷的菜叶和垃圾被白腻的泡沫包围着,一漾一漾的,填没了这只船和那只船的空隙。"这段描写给人留下的印象是船多、米多,暗示了丰收的年景。而这种丰收景象与后文农民的遭遇与失望形成了鲜明的对比,揭示了主题。
(4)引人入胜的悬念法。
就是从事件过程或人物经历中截取最关键,最紧张、最能吸引读者的一个情节做为文章的开头,然后再依次记叙事件发生发展或人物行为经历的始末。
(5)有关、警句、的引用法
名言开路,就是开头先引用名言、格言或警句,用以揭示文章的主题,然后再以所引用的名言、格言、警句为中心,组织材料,展开记叙。
例如,《琐忆》一文的开头是:鲁迅先生有两句诗:"横眉冷对千夫指,俯首甘子孺子牛。"这是他自己的写照,也是他作为一个伟大作家的全部人格的体现。……
这里引用的诗句,就是文章所要表现的主题。尽管文章中所记叙的都是琐细的事情,但所有的事情又能以小见大,体现诗句中的精神。
(6)表达写作目的的动机交代法
巴金的《永远不能忘记的事情》记述了各界人士悼念鲁迅的隆重场面,表达了人们对鲁迅的崇敬与怀念。文章的开头即交代了写作的动机,奠定了文章悲痛与激动的感情基调:"朋友,你要我告诉你一些关于那个老人的最后的事情。我现在不想说什么话,实在我也不能够说什么。我只给你写下一些零零碎碎的事情,我永远不能忘却的事情。"交代了写作目的的开头,多见于运用倒叙的方法、回忆往事的文章。
(7)首段设问法首段设问,就是在开头提出一个问题,然后再针对问题,逐步展开记叙。例如,《谁是最可爱的人》开头三段构成一个层次,用来提出"谁是最可爱的人"这个问题,从而引出下文的记叙。运用这种技法,要注意提出的问题必须紧扣文章的题材或主题,否则,下文的记叙就无所依托了。
文章开头的写法是多种多样的,这里不过提示了其中常见的几种。在写作当中,有时并不能单一地使用某一种方法,而是几种方法兼而有之。究竟使用什么方法开头,要从文章的整体构思出发考虑,要从表现中心思想的需要出发,通篇安排整体设计,选择最恰当的开头方法。
