五年级说明文范文(篇一)

我们每个人,都随时随地随身带着五官,永不离身。头上的五官,形态不同,各个的作用也不一样。各有所长,各有所短。

眼睛,是心灵的窗口,有他在,可以看到周围的一切事物。在野外旅游时,他称第一功,不断的把一幅幅画面呈现给大脑;在读书、看报、写作业,甚至是玩游戏的时候,他不都是不辞辛苦的把一幅幅别有深意的画面呈现给大脑吗?但是,他也有缺点,就是脾气太暴,当你过多的干用眼的是的话,他干脆跟你来个近视,当你后悔不应该用那么多眼的时候,已经晚了。平时,眼睛没有坚硬的“保护罩”,只有软软的眼皮,也非常容易受伤。

鼻子,是人体非常重要的一处器官,好处当然是给人们带来了新鲜的空气,鼻腔中的软毛过滤着空气中的细菌,支持着血液的循环。设想:人没有了鼻子,怎么呼吸?可以用嘴呼吸。就算嘴能维持个三天五天,但它能维持一辈子么?就算能维持一辈子,空气中的细菌就够你喝一壶的。看来,鼻子是一个非常非常重要的器官。但是,它的性情也是火爆的很,没事给你来一个鼻炎,你就得三天五天不能呼吸,但比眼睛的暴躁好多了吧~

耳朵,是一个听觉器官,能力莫过于就是听东西。听音乐,可不能少了他,不然,什么就都听不见了哦~但是,它也有缺点,比如说它长得就不好看。

嘴巴,也是每人都必须有的器官,若没有嘴,还怎么吃饭?人就没法生存,更没法用电脑写作。

眉毛,其实没什么用的,但是,却把人的相貌大大的改变了。所以,没有它,是绝对不行的。

眼、眉、耳、鼻、口,一样不能少。否则,就没法构成自己了哦~

五年级说明文范文(篇二)

The achievement of progress, prosperity and development for all the people in the world is a theme raised by UN. Alleviating poverty has been one of our government’s top priorities for the past decades. And poverty in remote areas in China is virtually a great obstacle for the Chinese to get common progress; thus, it is urgent for us to help the people there to shake off poverty the

sooner the better. For this aim, the government has already sent technicians and experts to poverty-stricken areas to help boost local agricultural production and teach the locals new techniques. The Ministry of Labour has also trained many rural labourers through different programs. But all these are not enough. Several other ways out have been proposed as follows.

First of all, the government should encourage a small part of the people in the remote areas to get wealthy ahead of others by equipping them with relevant funds and agricultural technology. These “better-offs” can not only set a good example but also give confidence to the poorer in their efforts to get rid of poverty. When all the people get rich, the general level of living standard can be greatly improved. And with their living standard improved, they can attach greater importance to environmental protection and are willing to input considerable amount of money to educate their children. Only in this way is a sustainable development guaranteed.

Secondly, we must call upon people in all walks of life throughout the country, especially those citizens of affluence in coastal areas to help those struggling below poverty line in poor remote regions out. We must realize that only after all Chinese people live a comfortable life can we be peacefully enjoying material prosperity in life. Helps can come in various forms----donating money to the poor family and books to school drop-outs, college graduates volunteering to work in the most needed regions, bringing knowledge to them, etc.

The last but not the least, the government should raise the rate of tax levied on those very rich. This can shorten the gap between the poor and the rich as well as benefit the country’s revenues whose better part is in turn allocated to the poor remote areas.

Admittedly, it is never easy to cast off the shadow of poverty in the remote areas completely in short run. But everyone of us should go all out to help those in poverty, we are confident that our country will be more powerful and prosperous in the process of alleviating poverty. (422words)

我们随时随地带着五官。五官,缺一不可。五官是我们身体重要的部分,假如没有了他们,行动也就很不方便了。

鼻子位居中央,端端正正的,它的作用可大呢!每次吃饭第一个闻到香味的总是它,如果煤气漏了第一个闻到的也是它,这样,它就救了人们的命,人们总是要感谢它。上天给了我们两个鼻孔,是要我们不要用同一个鼻孔出气。

俗话说得好:“眼睛是心灵的窗户”,眼睛有大有小,当我们过马路时,需要用到它;当我们写作业、看书时,也需要用它;当我们看电视、电影时还需要用它。它的用处可真大啊!可是,一到冬天,只有它冷,其他部位被裹得严严实实的,而它,一天只有睡觉的时候,眼睛才是闭着的,人们一醒,它就要工作了!上天给了我们一双眼睛,是要我们去用眼睛来探索大自然的奥秘。

经常与眼睛合作的是眉毛,当汗珠掉下来时,有眉毛帮它挡住,当雨淋下来时,有眉毛帮它遮住。但是,虽然眉毛做了这么多,却得不到人们的重视,人们感谢它,上天给了我们眉毛,而我们却不会珍惜、重视他。

耳朵在脸的两侧,耳朵可以听见人们所讲的东西,帮助我们记忆。上天给了我们一对耳朵,是让我们去倾听别人的心声。

嘴巴不同于其他部位,它只要张开口,吃食物,喝东西,这就是它的工作了。当然它也有一个搭档与他一起合作,那就是――嘴唇。每当人们吃到好东西,人们总会感激它。上天给了我们嘴巴,是想让我们尝遍天下的美食。

五官就是这样普通,但它却不平凡,只有它们团结一致,协调人们,就没有有用无用之分了。

这一天小主人小艾开了一个聚会回来了,小主人眉开眼笑,可能有点儿累了吧?所以小主人很快就睡了。

不知怎么回事,五官们就吵了起来,耳朵兄弟开心的说“今天我让主人听到了很多美妙的音乐,主人特开心,我是不是很伟大!”他正心花路放时,眼睛撅着嘴说“如果没有我,主人连那高大美丽的房子都看不到,还会那么开心吗?”鼻子大摇大摆的走了过来,说“我的功劳是最大的,如果没有我,主人闻不到香味儿,他会那么陶醉于那美丽的场景吗?我是世界上第一位大的器官”。这时小红嘴巴,拍拍胸脯说“我才伟大!没有我,小主人可不会有口福哦!没有了味觉小主人应该会很惨吧!所以我最伟大。”“我最大!”“我才最大!”

他们越来越大的吵声把小主人都吵醒了,他听见五官们在争吵,就说:你们来比比谁能让我开心就算谁最棒。“比就比!”五官们异口同声的回答。

比赛开始了,耳朵先跳了出来,他想把主人带到楼下听他最喜欢的音乐,结果他把小主人带到墙根去了。大伙都笑了,眼睛说“我来我来”,眼睛径直把主人带到了餐桌前,结果小主人闻不到任何味道,一点食欲也没有。这下鼻子开心了“看看没有我不行吧!”,可小主人一点也不开心,那么香的味道就是吃不到。这回嘴巴得意极了,可小主人一脸的苦闷。这下五官们着急了,都想让小主人开心一点,可不管是谁也没把小主人弄开心了。最后他们都围上来了,这下小主人的五官都集齐了,小主人又像先前一样开心了。

他们终于知道了他们每个都重要,缺一不可。大家以后再也没吵过架了。

五年级说明文范文(篇六)

Write an expository essay on the problems man will be faced with in the new century.

In the new century, human beings will be filled with hope and live more advanced life. What used to be depicted in science fictions can be the reality of the near future. However, man will also have to confront with some problems that will curtail(剥夺)human beings of their existence.

First of all, pollution of all forms such as land pollution, noise pollution, air pollution and water pollution are worsening with each passing day. People complain all over the world that it is becoming harder to breathe and water is turning undrinkable. Also forests are being felled at a very fast rate. The pollutions are getting so terrible that in some countries we can’t find clean and clear rivers and white clouds in the sky! When the children draw a picture of their surroundings, they paint the green trees in gray, the red sun in gray, everything in gray, and they can’t find a pure environment except in the books.

Additionally, the explosion of population in some parts of the world is manifesting its terrible results. Human beings wil1 have outgrown the earth’s resources, and people will run a high risk of starvation and diseases resulting from overcrowding. In due course, man would be forced out of the earth if the present trend were not reversed.

What is more, in the past century we had many disastrous wars. But there is still potential that the atomic bomb will be used by some politicians in order to keep regional hegemony. If it should happen, the exp1osion could easily lead to the destruction of civilization.

More seriously, the depersonalization of human relationships and the weakening of spiritual values are aggravating due to the stress caused by the busy schedules and the extreme pursuit of money. This will further contribute to man’s isolation and loneliness.

Apparently, with all these problems facing human beings, it seems to be overwhelmingly urgent to conquer them one by one because we have only one earth and it is our home. In the new century, we must try our best to heal the world and make it a better place for you, for me and for the children who will come to this world.

五年级说明文范文(篇七)

According to one of my teachers who graduated from university in 1983, his college expenses were only about 20 yuans per month, covering everything, such as food, and daily necessities. About twenty years later, the expenses of college students are dizzily/staggeringly high and growing more so every year. The basic average cost per student at public universities is now estimated at 15,000 yuans or more, including all the expenses for food, tuition, accommodations, bills for communications and fare for transportation, and other fees. The public universities having the benefits of receiving government investment in higher education are charging students high, to say nothing of the private universities which run on their own capacity.

Take myself as an example. At the beginning of this term, I was charged more than 6,500 yuans for the tuition of the academic year, plus 300 yuans per month for my dormitory accommodation, 500 yuans for the expenses on food, clothes and trivial items, 50 yuans for my mobile phone, etc. Every year, the expenditure totals as much as 20,000 yuans, which has eaten into almost half of my parents’ annual incomes.

Because going to college is so expensive today, many students have to drop out and go to work early, while others take part-time jobs to earn some money in order to lighten their parents’ financial burden. I am really keen on the experience in attending the universities and I have acquired a lot of knowledge since I came to this university. I am grateful to my parents who work hard and live thriftily to support me. Because of this, I am not only very careful in spending money, but also studying hard to live up to my parents’ expectation. Someday, I can say to them that every penny they have spent on my study is worthwhile and will be paid off.

说明文写作_高中说明文写作技巧

说明文,即用来解释或说明事物、理论、方法、过程或某种抽象概念的文章。说明文的基本目的就是说清楚。也就是说,要让人看了文章后对文章中解释或说明的对象有清晰明确的认识。这就决定了说明文的基本特征是客观和科学。

说明文首要的一点是明确说明的 对象,然后用准确的语言,结合多种说明手法对之进行介绍和描述。常用的说明手法有下定义、分类别、作比较、引资料、举例子、列数字、画图表等。下定义,即给要说明的对象下一个明确的定义。如博物馆的定义就是征集、保藏、陈列和研究代表自然和人类的实物,并为公众提供知识、教育和欣赏的文化教育机构。分类别是将要说明的对象按照某种标准划分类别,以帮助读者对事物的理解。如电视机,可以分为彩色电视机和黑白电视机。作比较,即将这种事物与那种事物比较异同,从而更清楚地说明事物的特点。如将城市和乡村作比较,将大学和幼儿园作比较等。作比较的时候一定要注意比较的事物之间应当具有可比性,不能生拉硬扯,也不能不尊重客观事实,胡乱比较。为了说明某种事物的特点,有时候需要介绍它的背景、原理、历史等,这时就要用到引资料这种手法。比如我们要对长城进行说明,适当地引用一些历史文献,就更有助于今天的人们了解长城的历史,从而加深对长城中所蕴含的民族精神的认识。在复杂说明文中,列图表具有不可替代的优势。大量的数据、冗长的叙述、复杂的相互关系等,都可以通过图表得到直观的表达。

按说明的对象不同,说明文可分为事物说明文和事理说明文。前者着重在于说明的成因、构造、形状、用途等,后者则重在说明事理。这两类说明文常用的写作手法也有一定的区别。比如事物说明文重在说明事物的物理特征,常用的是下定义、分类别等说明手法,事理说明文重在说明事物的逻辑特征,地要用到引资料、作比较等说明手法。但时候,在同一篇文章中,几种说明手法都要用到,相辅相成,互为补充。

如何使说明文物理并重、形神兼备的呢?首要的一点是观察。说明文写作的前提是对要说明的事物非常熟悉。要做到这一点,就要养成认真观察、深入了解的习惯:

观察要有针对性。要带着问题观察,而不是走马观花、浮光掠影。最好能在观察前列出观察提纲,观察时要记笔记、画图标。要善于提出问题。

观察时要分清主次。这就要求我们注意观察的顺序。观察有概括性观察和特写性观察之分。前一种方法有助于抓住事物的概貌,后者则利于把握观察对象的细节和特征。由概括到特写、由全局到局部,是观察的一般原理。

观察重在事物的形。要想传神,写出事物的内涵、原理等,则需要有很好的查阅资料、作调查的能力。比如我们要写一篇文章来说明洛阳牡丹。在写好它的形状、颜色、品种之外,如果能够考察一下洛阳牡丹的来历、其中的牡丹名品在培育中的科学原理,这篇文章就会有说服力,使读者更深刻地认识到洛阳牡丹的文化特色。这就要求我们具备相当的知识积累、广阔的知识面和优秀的调查能力。作为小,应当从小注重积累知识和调查能力的训练。比如通过剪报、记笔记、上图书馆和阅览室等途径来有意识地训练自己。

写作说明文还要注意说明的顺序。有合理的顺序,文章才能条理清晰,让人看得明白。说明顺序一般有三种,即空间顺序、时间顺序、逻辑顺序。间顺序一般有从上到下、从左到右、从前到后、从远到近等。时间顺序一般有从古到今、从过去到现在等。 逻辑顺序有从现象到本质、从原因到结果、从主要到次要、从整体到部分、从概括到具体等。什么是合理的顺序呢?这要根据人们认识事物的过程以及说明对象本身的特征、规律而定。说明事物的形状、构造等,往往以空间为顺序;说明事物的成因、方法,往往以时间为顺序;说明事物的事理,往往以逻辑关系为顺序。

当然,大多数说明文会综合使用多种说明顺序。因此,在写作时,我们要合理地安排好说明顺序,理清说明文的结构层次。常用的结构层次有并列式、层进式和总分式三种。比如我们以“水”为题目进行写作,可以先写水的外形特征,再写水的分类,然后写水的用途,这是并列式的写作层次。我们也可以先写水的外形,再写水的成因,最后写水给人类带来的利与害,这是层进式的结构层次。先概括水的用途和特征,再一一细述,就是总分式。结构层次能力需发们在长期的写作过程中培养,现在就不一一细说了。

五年级说明文范文(篇十)

传说水仙花是“凌波仙子”的化身,其实它是多年生草本植物,属于石蒜科,盛产于我国福建省的漳州地区,至今已有500多年历史了,是中国传统十大名花之一。水化花喜欢生活在潮湿的地方,多长在水中。如果它生活的地方温度较高,就会吸收大量养料长出很多叶子,而开的花就少了。人们都希望水仙多开花,少长叶,花期长,那应该怎么办呢?

雕刻好的水仙头要放在水里浸泡一天左右。浸泡出根茎中的粘液后,用清水冲洗干净,再把刀削的伤口用干净的白色餐向纸(便于以后拿掉)轻轻地缠绕上,以利吸收水分,促进根的生长。洗净、包好的水仙头一般都摆放在紫砂水仙盆中。在盆底部码上干净漂亮的小石子,用来稳住水仙头,再注入清水后,我们的工作就基本完成了。

最好的办法就是雕刻水仙。

拿到一个3年生水仙头后,应该先判断正反面。水仙头露出的芽弯曲的一面是正面。雕刻水仙花头正面的方法是:首先把水仙花外面的鳞片和干枯的根削掉,其次把水仙花头靠根部的1/3留下不动,一层一层地削掉上面2/3部分的鳞片,直到露出花芽为止,再在每片叶梢的边缘削一下,以后花芽就会弯曲生长、能形成漂亮的造型。雕刻时请注意不要把花苞削破,以免影响花蕾的生长。

水仙花盆要放在阳光照射比较少的室内,室温控制在8-10C左右,坚持每天换水。经过5-6天,水仙花的苞蕾就会一个一个地长出来,叶子会呈现弯弯的形状。这时,它生长很快,应该适时调整温度,使它在将近春节时开出花来。如果温度、湿度控制得好,花期一般在半个月左右。如果雕刻技艺精湛,便创作出一盆盆活灵活现的“天女散花”、“花篮迎宾”、“孔雀开屏”、“天鹅展翅”等盆景,使清香飘逸的水仙花更加多姿多彩,使人得到一种艺术享受。

新春佳节来临,优雅的水仙花伫立于一泓清水之上,亭亭玉立,竞相开放,散发出淡淡清香,定会给您的新春佳节增添无限的情趣,给您的居室带来春天的气息。

五年级说明文范文(篇十四)

Huge population is one of the main problems in China. Since the 1970’s the Chinese government adopted a policy of family planning---- single-child policy---- as a basic state policy to solve this problem. Until now, this birth control policy is still implanted in our country and both positive and negative effects have been harvested.

With the adoption of the family planning policy, the rate of population growth has been successfully controlled. This has already brought about some satisfactory results in China. For one thing, people’s living standard has been greatly improved with our country becoming more and more prosperous, and our national economy developed steadily. Furthermore, with decreasing population, the problem of shortage of water in parts of China is solved gradually. In addition, with the low rate of birth, it goes with less energy consumption, which will benefit the overall development of our economy. Moreover, this policy has greatly reduced the financial burdens of the parents who have otherwise had more children, enabling them to focus their resources on the single child’s well-being and education.

However, the implementing of this policy also brings about some problems. First of all, as there is only one child in a family, the child becomes “little emperor” or “little empress” of the family, surrounded by parents and grandparents. The spoiled child can get whatever he likes and discards whatever he dislikes. This phenomenon is more popular in large cities will do great harm to the children themselves. They don’t cherish what they have got because they can easily get whatever they would like to. Worse still, in the future when they grow up, they might feel very difficult to adjust to the society or cope with the adversity. Some people also show great concern that when the single children get married, the couple have to take care of 4 old people.

While admitting that single-child policy does bring some negative effects on the single child, we must take it for granted that it has benefited and will continue to benefit the country. Therefore, we should carry it one and at the same time adopt some measures to avoid the adverse consequences the policy may produce.
