The Importance of Reading Literature
Literature is acknowledged as the most precious product of human civilization and wisdom, especially by our teachers. So they always ask their students to read as many as literary works. Just as the drawing shown above, a teacher gives a literary work to her student, saying: “Just think of it as if you’re reading a long text-message.”
It is of great significance for us to appreciate literature due to the following reasons. Firstly, a good literature can get you to know a life experience through the eyes of someone other than yourself. The more experience you gain, the more knowledgeable you are. Secondly, a good literature allows you to learn about history in a personalized way. The stories told in the works can act as mirrors and help you adjust your own behaviors. Lastly, a good literature is an effective way for relaxation. The beautiful and moving scenes shown in the literature are helpful for one’s mental health.
In short, literature is indispensable in our life. We, students, should catch our time to read more literatures.

Perhaps you have heard a lot about the Internet, but what is it, do you know? The Internet is a network. It uses the telephone to join millions of computers together around the world.
Maybe that doesn’t sound very interesting. But when you’ve joined to the Internet, there are lots and lots of things you can do. You can send E-mails to your friends, and they can get them in a few seconds. You can also do with all kinds of information on the World Wide Web (WWW).
There are many different kinds of computers now. They all can be joined to the Internet. Most of them are small machines sitting on people’s desks at home, but there are still many others in schools, offices or large companies. These computers are owned by people and companies, but no one really owns the Internet itself.
There are lots of places for you to go into the Internet. For example, your school may have the Internet. You can use it during lessons or free time. Libraries often have computers joined to the Internet. You are welcome to use it at only time.
Thanks to the Internet, the world is becoming smaller and smaller. It is possible for you to work at home with a computer in front, getting and sending the information you need. You can buy or sell whatever you want by the Internet. But do you know 98% of the information on the Internet is in English? So what will English be like tomorrow?
1. What is the passage mainly about?
A. Internet. B. Information.
C. Computers. D. E-mails.
2. Which is the quickest and cheapest way to send messages to your friends?
A. By post. B. By E-mail.
C. By telephone. D. By satellite.
3. Which may be the most possible place for people to work in tomorrow?
A. In the office. B. At school.

A. English is important in using the Internet.
B. the Internet is more and more popular.
C. Most of the information is in English.
D. Every computer must have the Internet.
【答案与解析】
这是一篇关于 Internet 的说明文，它介绍了什么是Internet，Internet 的用途，它的贡献等等。
1. A。主旨题。文章的每一段都谈到了 Internet，所以我们可以推断文章的主要内容是 Internet。
2. B。细节题。在第2段中谈到 You can send E-mail to your friends, and they can get them in a few seconds，相比其他选项，E-mail 当然是最快的。
3. C。细节题。最后一段的第2句讲到 It’s possible for you to work at home with a computer in front，所以明天我们极有可能 at home 工作了。
4. D。判断题。根据全文我们得知，我们可以在 school, libraries, home 等地方使用 Internet，所有的拥有者是大家，并不是某一个人或某一行业的从业者。
5. A。推断题。最后两句告诉我们：98% of the information on the Internet is in English，也就是说英语在 Internet的应用是非常广泛，非常重要的，除 A 选项外，没有一个选项能全部概括这句话的意思。

下一篇：我最喜欢的植物说明文作文400字
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。

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.
(因果法说明文)
中国是一个有着五千年历史的文明古国，中国素来是一个温文尔雅，落落大方，见义勇为，谦恭礼让的文明礼仪之邦。作为现代中学生，如何去继承这种优良传统呢?我想，首先要学习做人，做一名“守规则，守规范的现代文明新人”。
曾听说过这样一则报道：“新加坡是一个通用英语的国家，他们的各种标语，大多是用英语书写的，但其中一些标语，比如：禁止吸烟，不准进入草坪等等却用中文书写”。有人问为什么。他们回答：“因为这些不文明的行为大多发生在中国的游客身上。”不知，同学们听到这里有何感想？
在我们身边，有一些同学身上还存在着一些不文明的行为。例如，总能看到与我们美丽的校园不和谐的纸屑，总能听到一些脏话，粗话……我们把学习文化知识放在首位，殊不知文明习惯的培养，更能展现一个人思想品质。请大家不要忽略这些小事，“一屋不扫，何以扫天下”，正是这种举手之劳，更能折射出文明的光辉。
我想，作为一名高中生，我们更应该将最基本的礼貌礼仪铭记于心。我们应该要担当起时代赋予我们的责任，说文明语，做文明事。记得有人说过：“人，一撇一捺，写起来容易做起来难。做怎样的一个人，一百个人会有一百种答案。但是在每一个答案的背后都有一个基点，那就是文明。文明是不小心撞到对方后的一句对不起，文明是自觉将纸屑放入垃圾筒的举动，文明是见到师长时的温暖的问候……文明是一种品质，是一种修养，是一种受人尊敬并被大家广泛推崇的行为。
众所周知，咱们中国是一个历史悠久、文化丰富的国家，在源远流长的历史长河中，人们留下了许多美丽的传说、动人的故事、五花八门的风俗习惯和多姿多彩的民族艺术。
十二生肖是我国的传统文化之一，它与我们的生活紧密相连，今天我就给大家介绍一下这方面的有关知识。据说，十二生肖的排名是这样来的：传说有一年，玉皇大帝要在正月初九选定十二生肖。晚上，贪睡的老猫请求老鼠早晨叫醒它，如果不叫就吃掉它。可是正月初九清晨，老鼠却悄悄地独自出发了。老鼠不会游泳，却遇上了一条河，它偷偷地钻到牛耳朵里，顺利过了河。等牛刚要进门时，老鼠一下子从牛耳朵里窜了出来，抢先跳到了玉皇大帝面前。结果，老鼠得了第一名，接下来是牛、虎、兔、龙、蛇、马、羊、猴、鸡、狗、猪。每个人都有属相，我们的属相就是根据十二生肖的排列顺序来定的。
勤劳聪慧的劳动人民还根据十二生肖的形态做出了各种各样的艺术品。有精美的邮票、闪光的银币，有古老的金币、精致的挂件，还有美轮美奂的刺绣、五花八门的剪纸、奇形怪状的泥塑以及千奇百怪的布艺……真是精美绝伦，叫人目不暇接。
你看，我们的民族文化是不是绚丽多彩?如果你有兴趣，你也可以找一找有关的资料，和我们一起分享。

It goes without saying that english plays an important role in our modern society. english is an international language. wherever you go, you can hear english spoken by many people.
From this point of view, it is true that english is important to our daily life. learning english is like learning to swim or learning to play ball. our primary trouble is that we have tackled the study of language from the wrong end. we are like theman who thinks he can learn to swim only by reading books about swimming. in actuality, we learn by doing. the grammatical rules are valuable as we plunge into the language and need some assistance. in the same way, advanced instructions about swimming are helpful as we learn something from actual experience in the water. but reading books never makes a swimmer and learning rules never makes a practical linguist. the regular procedure in learning english involves listening first, to be followed by speaking. then comes reading, and finally the writing of the language. the way you learn english is much the same as the way you learned your own language.
First of all you must listen and then repeat and repeat until you can use the language easily. in other words, you have to build up language habits in english just as you build up english habits in your own language. to sum up, we must bear in mind that nobody can learn to swim for you. nobody can learn to play ball for you. nobody can learn english for you. it's up to you. you must learn for yourself and you will learn if you really want to and are willing to practice.

Many years ago, Shanzhai products were discussed by the public everywhere. Shanzhai means fake and low quality. At that time, most people didn't have the consciousness to protect the intellectual property right. The act of plagiarism will not only be condemned by people, but also punished by law.
许多年前，山寨产品在各地都被公众讨论。“山寨”意味着“假”和“低质量”，当时，大多数人都没有意识到保护知识产权。剽窃行为会不仅不会受到人们的谴责，也不会受到法律的惩罚。
In order to call for the public to pay attention to the protection of intellectual property, April 26th has been named World Intellectual Property Day, which helps to advertise the value of one's own hard working. When someone creates products, he needs to register his patent, so as to protect his own wisdom to be stolen by others. Nowadays, more and more people start to realize the law's power to protect their creation.
为了号召公众关注保护知识产权，世界知识产权日定在了4月26日，这样有助于宣传一个人努力工作的价值。当有人创造产品时，他需要注册专利以此来保护自己的智慧被他人窃窃。现在，越来越多的人开始意识到法律的力量来保护他们的创造物。
For those people who plagiarize other people's design, they should be punished by law. It is a shame to make Shanzhai products. What they do not only hurts the designers' feelings, but also brings great loss of customers, because no one wants to get fake products.
对于那些剽窃他人设计的人，他们应该受到法律的惩罚。制造山寨产品是可耻的。他们的所作所为不仅伤害了设计者的感情，也给顾客带来了巨大的损失，因为没有人想要买到假货。
Still there is a long way to go for better protecting designers' original creation.
要想更好地保护设计师的原创作品，还有很长的路要走。
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.
(举例法说明文)
说明文是说明某事物、事由或过程等的文章。它用于说明客观事物的特点和本能，或介绍某种操作的程序，或解释某些抽象概念，阐明某种科学原理、自然理解等，完全是就事论事的描述，因此也称为技术性的描写文。
说明文应该写得条理分明，层次清楚，语言简洁，用词具体，具有严密的逻辑性。说明文写作时应注意下面几点：一篇文章集中讲一个主题;叙述顺序要清楚，即按时间、空间或重要性的'顺序进行分层叙述;例证要具体充分，切忌空泛笼统;叙述既富于说理，又生动活泼，使文章更吸引读者。
下面介绍几种常用的说明文写作方法：
1.例证法
是用具体例子说明人或事物的特点、本质及其规律的方法。所选例子必须有代表性、典型性。
2.定义法
定义法是用来解释、限定某种事物或概念的写作手法。下定义是多方面的，可以给人、事物、思想、概念等下定义。定义法说明文往往要利用其他写说明文的手段，如举例、对比、归类等。
3.分类法
分类法是对同种不同类或同类而不同种的人或事物，根据其不同性质进行分门别类说明的方法。分类法的特点是：段落布局合理，类别分明，井然有序，相互映衬。

二十六号九点是查英语四级的时间，早上迷迷糊糊的起来，第一件事情就是看时间，已经九点多了，起床拿起手机登陆网站查询自己的四级成绩，好不容易登陆上去，显示“查询人数过多，请稍后再试。” 看到这行字，并不甘心，换了一个坐姿又查了一遍。
尽可能的睁大眼睛，总分460，噢耶，过了！425过四级，想起来复习的日子，厚厚的一本四级单词，还有十套题，其实我没背多少单词，题也只是考前做了几套。但是每天都看一部英文电影，锻炼听力，做题的时候，每个类型题都认真的分析，琢磨。作文也看过很多，这是我第二次考英语四级了，分析第一次的成绩，有听力，阅读，作文和翻译，这三部分我的得分都不高，一百二十多分，总分是358，这次我苦练听力，做阅读的时候也很认真，单词虽然没背完一本，但是也背了百页。
这次成绩比上次提高了一百多分，我也很高兴，也为自己感到自豪，我的作文和翻译部分不好，这次也不例外，听力和阅读都是一百七。
刚刚结束考试的时候感觉答的还不错，但是一想到单词没背完，心里也是没有底。回宿舍以后，室友都在讨论题目，每人的题目不同。室友也都考了，可惜的是算我总共两个人过了。问了问我以前的同学，也没有过，不过她们都是第一次考，还有机会。
在微博里也搜了一下四级，看到很多人发的都是四级，当然还有六级，如果时间充足，我也把六级过了，以后成为英语老师也是可以的，哈哈，加油。

Since I went to college, I feel so excited about the new chapter of my life. I have imagined the campus life for so many years. Now I finally come to this stage. I have much time after class, so I need to learn to deal with it. After two years’ struggling, I find the right way to spend my time.
自从我上了大学，我对生活的新篇章非常兴奋。我对这样的校园生活已经想象了好多年了，现在终于到了这个阶段。课后我有很多时间，所以我得学会处理。经过两年的挣扎，我找到了消磨时间的方法。
The first thing for every college student is to learn major knowledge. In China, so many students think college time is used to play instead of study, so they skip class. This is a big mistake. College is the stage for students to master practical skills, which decides what kind of job they will work on. So I study very hard from Monday to Friday. I don’t want to miss the important knowledge.
对每个大学生来说，第一件事就是学习专业知识。在中国，很多学生认为大学的时间是用来玩而不是学习的，所以他们逃课。这是很大的误解，大学是学生掌握实践技能的舞台，这决定了他们将来从事什么样的工作。所以从周一到周五我都在努力学习，我不想错过重要的知识。
The second thing for college students is to join the after-class activities. Joining the activities can not only learn more skills, such as dance and sports, but also can make friends. Campus is like a small society. Students need to learn to make connections with other students, so that they can win more chances. I learn a lot from my new friends and know how to communicate.
对于大学生来说第二件事就是参加课外活动。参加活动不仅可以学到更多的技能，比如舞蹈和运动，还可以交到朋友。校园就像一个小型社会，学生需要学会与其他学生建立联系，这样他们才能赢得更多的机会。我从我的新朋友那里学到了很多，也知道如何沟通。
My college life is wonderful, I learn both knowledge and social skills.
我的大学生活很棒，我学到了知识和社交技巧。
Grain rain is the sixth solar term of Chinese traditional festival, which is also the last solar term in the spring season that means the coming of summer and the warm weather helps the grain to grow quickly. Nowadays, different areas have different ways to celebrate this festival.
谷雨是中国传统节日的第六个节气，也是春季的最后一个节气，这意味着夏季的到来和温暖的天气将有助于粮食快速生长。如今，不同的地区有着不同的庆祝方式。
About 4,000 years ago, the emperor named a man to be the government officer. The man's job was to use shells and knots to records incidents, but soon he found this way wasn't effective due to the raise of incidents. Finally, he created the words and the emperor made a big celebration. Then it rained with grain, so people called this day Grain Rain.
大约4000年前，皇帝任命一个人为政府官员。这个人的工作是用贝壳和绳结来记录事件，但很快他发现这种方式随着事件的增加而行不通，最后，他创造了文字，皇帝也举行了一场盛大的庆祝活动。后来下雨了，所以人们把这一天称为谷雨节。
Since then, when Grain Rain comes, people would celebration for seven to ten days. People built a temple in honor of this great man. Thousands of people came to the temple to join the activity. They danced and made big performances. Now, people feel so grateful about the rain, which gives them hope of big harvest.
从那时起，当谷雨来临的时候，人们会庆祝7到10天。人们建了一座庙来纪念这位伟人。成千上万的人来到寺庙参加活动，他们跳舞和表演。现在，人们非常感激雨，因为雨给了他们大丰收的希望。
Though people made different traditions on Grain Rain, they are all thankful to the coming harvest.
尽管人们在谷雨节上的庆祝方式不一样，但他们都对即将到来的收获表示感谢。
在我们生活中，有许多精美的物品，香甜可口的水果、营养丰富的蔬菜、美观实用的电器、漂漂亮亮的玩具……
我们身边的事物千千万万，怎样才能抓住事物的主要特点进行描述呢？今天这节习作课，就让我们去观察一个自己了解并感兴趣的事物，并将它介绍给大家。
说明文和一般的记叙性文章有什么不同？回忆一下学过的说明文——《太阳》《松鼠》等，总结学过的说明方法及说明文中语言的准确性和生动性等特点。
《太阳》一课中，介绍了太阳的（远）、（大）、（热）等方面的特点以及太阳（与人类的密切关系），运用了（列数字）、（举例子）、（打比方）等说明方法。
《松鼠》一文中，介绍了松鼠的（漂亮）、（驯良）、（乖巧）等特点，采用了（打比方）、（作比较）、（列数字）等说明方法。
写说明文，要从不同的方面介绍事物。你打算从哪些方面介绍事物？
第一步：确定好要写的物品（审题）。
第二步：认真观察，找到物品的特点。1.介绍蔬菜、水果，应重点介绍形状、颜色、味道，还可以介绍种类、产地、产量、营养价值、保鲜等方面的情况；2.介绍玩具、文具、电器，应重点介绍形状、特点、构造、用途以及使用过程中应注意的问题等等。
第三步：具体描写，结构有条理。
叶圣陶爷爷认为：“说明文以‘说明白了’为成功。”写说明性文章之前，要做好观察、搜集好资料，对事物有充分的了解，并且要想清楚从哪几方面来介绍。结合说明性文章的特点，教材从内容、方法和篇章布局三方面提出了写作时的具体要求。
拟写提纲
（1）引出说明对象，点明写作对象的特点。
（2）写特殊来历及意义、外形特点、结构特点、使用价值等。
（3）总结全文，进一步强调它的特点，表达喜爱或珍惜之情。
除了写动物、植物，还可以写一写新奇的、冷门的物品，或者更贴近日常生活的美食等，这样可能会吸引更多的读者。
在拟题方面可以像《恐龙》一样，直接、明确地点出说明对象；可以像《袋鼠的自述》一样，运用第一人称的写法；可以像《种子的旅行》一样，运用拟人手法，让题目生动有趣；可以像《怎样泡酸菜》一样，提出疑问；也可以像《火星的秘密》一样，引人遐思。
例1：我觉得食肉植物很神奇，我想了解相关的知识，所以我准备介绍几种食肉植物，我给习作命名为《植物“猎手”》。
例2：我对风向袋的制作很感兴趣，也想把制作方法教给更多的人，所以我准备介绍怎么制作风向袋，我给习作命名为《风向袋的制作》。
可以从哪些方面介绍事物的特点呢？动植物可以从外形、种类、分布、习性等方面介绍；物品可以从形状、构造、用途、注意事项等方面介绍；美食可以从营养价值、制作方法、发展史等方面介绍。
怎么搜集到相关的资料呢？（搜集资料的方法——观察记录和查阅资料。一些事物的制作过程，我们可以进行细致的观察；一些生活中常见的事物，我们也可以通过观察去将它介绍明白。一些把握不准或不知道的内容，可以通过查资料去将它介绍清楚；一些生活中不常见的事物，也可以通过查资料将它介绍明白。观察和查资料都是围绕将事物的特点“说明白了”这一目的服务的。
为了把事物介绍清楚，可以恰当运用哪些说明方法？（几种常见的说明方法及其作用：如，列数字的方法能科学、准确地说明事物的特点；打比方的方法能生动、形象地说明事物的特点；作比较的方法通常要与常见的事物比较，从而突出说明对象的特点；举例子时，举出的例子要通俗易懂）。
Showing respect to parents is one of the Chinese traditional moral most of the students today are “the only child” in their family, they often regard themselves as the“centre”of the family, without caring much about their parents. Our school started a programme when the new year is “Respecting parents programme”. Ten“Do＇s”have been worked out for the students to follow clearly and easily, including:
“Remember your parents＇birthdays and express your best wishes to them; say”hello“to your parents when you see them returning home; and tell your parents where you go when you leave home.”
The programme has been successful, and has won praises from parents and other sides of the society. People say this is what we should have done earlier!
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。
大学英语说明文范文200字 第9篇
南京是六朝古都，也时青奥会的举办方，我作为东道主，大家介绍介绍南京的风景名胜——明城墙。南京古城墙修筑于明朝，仅内城周长就达33。7公里，比周长仅29。5公里的巴黎城墙还长。古城墙是朱元璋经过3年准备，经历4个阶段共时间才建成的。朱元璋为了建造南京古城墙曾下令5省、20州、118县烧制城砖。为了保证质量，每块砖上都要打上烧制的州、府、县及工匠和监造官员的姓名，如不合格一律退回重做，再不合格就将治罪。可见严格之极。这些城砖长40～50厘米；宽20厘米左右，厚度不少于10厘米。其总数约为3亿5千万块。这些数字也显示出了明城墙的宏伟。
南京的城墙，为中国古代军事防御设施、城垣建造技术集大成之作。无论历史价值、观赏价值、考古价值以及建筑设计、规模、功能等诸方面，国内外城墙都无法与之比拟，可谓是继中国万里长城之后的又一历史奇观。明城墙的13座城门的上部，都建有高耸的城楼，而以聚宝门最为雄伟。聚宝、三山和通济三座城门各有城墙四道，每两道之间的空间称为“瓮城”，可作为战时的防守之用。聚宝门是这些城门中最 坚固的一个，城楼以下部分基本保存完整，而且有所谓“藏军洞”的特殊设施。“藏军洞”实际上就是里端封闭的砖券门洞，在战时可供兵士休息和用来存放军事物资。这种“藏军洞”在聚宝门最南一道的城墙上计有两层共13个，左右两侧的城墙下部又各有7个，加起来有27个。据说，每洞可容纳兵士100人以上，共可藏兵达3000人以上。这种设施在中国古代的其他大城中是极为少见的。
每座城门都有内外两道门，外面一道是从城头上放下来的“千斤闸”，具有坚固的防御作用；里面一道则是木质再加铁皮做成的两扇大门。在平时，行人车马都从城门洞里通过。明城墙的历史悠久是南京人的骄傲！

说到酸菜鱼，我就忍不住咽了咽口水，因为那酸酸辣辣的味道很诱人。趁今天是母亲节，我决定做一盘酸菜鱼。
首先，我先去超市买了一条新鲜的草鱼，还有酸菜、辣椒、生姜、大蒜、鸡蛋等做酸菜鱼的材料。一切准备就绪，我便开工了。先将鱼去鳞，去内脏，切片；然后加入淀粉、食盐、鸡蛋清搅拌腌制。接着，把刚才准备好的酸菜、辣椒等调味料放入锅中翻炒3分钟，加入适量的开水，煮了3-5分钟放入鱼骨，再熬3分钟放入鱼片煮熟。最后，起锅加入葱花，酸菜鱼就算大功告成了！这一切都做得很顺利，看着自己做得酸菜鱼，我满意极了，禁不住夹了一块鱼肉，嗯！不愧是大厨师，我不禁夸了夸自己，因为实在是太好吃了：肉，鲜嫩爽口，汤，美味可口！
我赶紧将酸菜鱼端出去给妈妈品尝，妈妈尝后，点点头说：“太好吃了，真是青出于蓝而胜于蓝，比我做的还好吃。”听了妈妈的夸奖，我更得意了。
酸菜鱼是怎么来的呢？，我上网查了查资料，关于酸菜鱼的传说有许多，有一个传说是这么说的：壁山县有一个钓鱼翁一日钓得几尾鱼回家，老伴误将鱼放入煮酸菜汤的锅里。后来一尝，鲜美至极，鱼翁逢人就夸，酸菜鱼也出了名。
酸菜鱼真是一道舌尖上的美味，它营养丰富、开胃健脾、醒酒提神，让人吃了回味无穷，还可以帮助消化呢！

英语四级！
精读是真正意义上的精确阅读。把做题的想法暂时抛开，从标题到结尾，每一段、每一句、每一个单词，都要弄清楚是什么意思。这样每篇文章可能至少要花一个小时才能吃透，把每个隐藏的语法都挖出来。如果觉得困难，可以从最简单的做起。比如对不懂的单词，把成分划出来，联系上下文猜它的意思。
这样的精读训练至少要坚持半个月到一个月，每天都要分析2篇以上的文章，才能见到成效。
2.对症下药，循序渐进，注意速度
当对文章句子的结构有了较好的`把握后，就要逐渐增加难度。做一定的练习后应定期总结，以便及时发现自己的薄弱环节，然后再有针对性地去加以弥补。
考试是有时间限制的，用在阅读选择题部分的时间也是有限的，所以在平时的练习中要注意自己的做题速度，一般来说，做一套阅读选择题最好不要超过70分钟。
3.记住一些小诀窍
考试时可以运用一些小窍门以达到事半功倍的效果。比如做阅读理解部分时，先将题目通读一遍，再读文章，这样能减少解题时间，加强对文章内容的把握，使阅读理解有重点地进行。

大学英语说明文范文200字 第15篇
Dear all,
I am writing this letter to express my gratitude to my parents for teaching me to be positive and to be strong. “Educating the mind without educating the heart is no education at all.” is the opinion held by Aristotle. It is the experience of our forefathers, however, it is correct even today, including my parenting.
It is widely acknowledged that parenting, which can also be explained as family education, is of great significance in our character forming and manner acquiring. To be more detailed, setting good examples instead of just giving precepts is the greatest achievement of my parents. They not only taught me to think for the best and prepare for the worst; they taught me how. They not only told me the benefits of being strong in mind; they proved it. All those things require huge amount of time and work, but it’s worth it.
Without my parents’ contribution and education, I would never be who I am now. But most importantly, I would never be more gratitude to them than today.
Yours,

My View on Job-Hopping
Some people tend to stick to their positions all the time, as they think the longer one works in a particular field, the more skillful one will be at it. Some have been teachers all their lives. Some devote their life energy to scientific research. Such people love their work and turn out to be specialists in their own field. They are usually high achievers.
Some are different. They are in the habit of job-hopping, for they always pursue what is new and stimulating. They never seem content with their present situation. Some like to meet more people, make more money and new acquaintances, so they hop from job to job.
As far as I am concerned, I want to be professionally strong. I am not in favor of frequent job hopping, as the saying goes Jack of all trades, master of none. But I want to have opportunities for advancement and as many colleagues as possible to cooperate and communicate with so as to be more creative and less 12345下一页尾页

It is important to make sure that others know about your strengths and accomplishments; if you are not so,you will be never successful in life.
If people are unaware of your talents and other good qualities, you obviously will not stand out among your peers. To be successful you not only have to work hard, but you have to make sure others know you work hard, as well. Of course you should let others know of your strength and accomplishments, but the best way to let them know is by showing, not by just telling.
College applications-or applications of any kind-are a perfect example. Colleges want what kind of student you are and what kind of student you will be in college. You must show them that you are a good student and that you are interested in whatever you want to study. But in the essay, you cannot just state that you are a good student, are hardworking, and enjoy mathematics; you must show them. If you are interested in mathematics, then you probably did something in high school related to mathematics, such as the math club. In your essay, you must be sure to mention your participation in math club, but also activities your math club in order to show colleges that you will be active in your mathematics major. If you simply state that you like math, colleges will not be as impressed.
It is important to let others know of your achievements; otherwise you will not be successful in life. The field of science can provide many examples of the validity of this statement. In science, communicating your discoveries is as important as discovery things in the first place. Everybody knows that the scientists Watson and Crick discovered the double-helix structure of DNA. Many people are not aware that this model was first theorized by a female scientist working in the same lab as Watson and Crick. However, Watson and Crick published their findings before the woman published her own findings. In science, credit is given to whoever publishes first, so the Watson and Crick are given full credit for the discovery of the double-helix structure of DNA. In order to be successful, you must let other people know of your accomplishments.
Granted, there is a fine line between letting people know about your accomplishments and simply showing off.
Nobody likes a show-off, so you must be careful not to rub people the wrong way with your success. People always say that actions speak louder than words, which is good advice to keep in mind when you are trying to let other people
know of your success. Don't just tell people you're good at writing. Start a blog and show people how accomplished of a writer you are.
The key to success is to play to your strengths and to not be shy about showing other people your talents. (460 words)

四级英语
如果仅仅是为了过应试四级，只要方法对头不难的
1.你首先得把你的词汇量过关了，这个是基础，否则其他的东西都是空中楼阁，词汇是最最最最最最基础的东西，你拿一本四级词汇，每天花两个小时以上的时间来背，否则你的.后面的步骤完全没法开展，因为如果你词汇还没有过关，怎么复习都会觉得困难重重，无法下手。
2.听力其实是英语环节里最容易提高的一环，你可以从四级真题入手，不要嫌烦，五遍十遍的听，要听得自己都很清楚每一个单词的读音含义，更重要的是你能掌握到题目的考法，等你把所有的题目都听得很熟了你会发现那些题目的考法都是差不多的，究竟怎么个差不多法，你自己好好体会。
你如果要练听力，别去听英语广播那些东西，就你现在的状况，提高不会太快，就老老实实的听往年原题和四六级模拟体的听力，每天听，耳机随时挂耳朵上，你会提高很快的，只要你坚持努力，听力基本会不丢分的。
3.阅读是四级中分最重的一环，你一定要多读，最开始的时候，精读，每一句都读的很清晰，这个可以读往年真题，而且仔细体会考题答案和文章的关系，仔细体会考试的出题方法。十来套题精读出来，你心里肯定会对考的东西心里有谱了。然后开始大量的阅读，这个时候要注意速度，把阅读的准确性和速度提上去
4.作文来讲，只要你买一本专门讲写作的书，如果你词汇量过关的话，把历年的作文都写写，并找学的好的人好好改改，多背一些比较好的英语句子，写作文用处非常大，这个在很多教材里都有。一般来说掌握一些常用的巨型，就很容易写出很漂亮的文章了。

我吃过许多美食，有酥的，有软的，有甜的，也有辣的，可是，令我最喜爱的，还是那酥中带香，嫩中带些许臭味的榴莲酥了。
这种食物并不常见，它的外壳是金黄色的，就像一只金黄色的小船。它的内部是由一层层黄中带白的酥皮与软软的榴莲肉做成的馅，闻起来带着榴莲那种臭乳酪和洋葱混合的臭气，又有类似松节油的香味，轻轻地咬一口，一阵包含着榴莲甜美沁心的香味向你涌来，让你吃了还想吃，大有“榴莲”忘返之感。
榴莲酥的做法也很奇特，首先将面粉，蛋液和白糖，猪油混合，并加入适量的水，和成水油面团，再将面粉，猪油与黄油揉成油酥面团，然后将面团放入冰箱冷藏十分钟。接下来取适量水油面皮料在案板上压扁，擀成面皮，中间包上油酥，再次压扁擀成牛舌状并重复几次，将面皮擀成圆形并在中间包上榴莲肉，包成水饺一样的半圆即可。吃时再将它用油炸或烤成金黄色就可以了。
榴莲酥的吃法也很有趣，可以把它一层层打开，加上一点馅吃，也可以采用普通的吃法。有一次，我吃榴莲酥时，把里面的馅吃了，再吃它外面的皮时就没有什么味道了。
榴莲酥是一种十分有趣也是十分好吃的小吃，它的味道总是让人“榴莲”忘返，吃了还想吃。

一、熟悉和研究历年真题，熟练背诵所考作文的几种模板
背什么东西呢?很多同学会想到，就是背模版。模版这个东西是可以背的。
我们一般地来讲会把6级的作文分成5种类型，那也就是至少有5篇文章可以作为模版去背诵。
背模版又可分成5个档次：
1、最不好的其实就是没有背模版，自己还没有好东西，那叫“手中无剑，心中也无剑”，就是属于“裸考”，属于“等死”的档次。
2、比较好的，比这个好一点的是背模版，没有背好，没有用对地方，仅仅是第2档次，也就是“手中有剑，心中无剑”。
3、更好一点儿的是第3档次，就是背准了用对了，手中心中都有剑，但其实还不是最好的。
4、第4档次，就是大家更应该追求的，有自己的写法，模版的句子也可以变。
其实考过4级的同学，你在4级模版里面背的句子，6级作文同样可以用。还有，不管4级还6级的.模版，你都可以把一些词儿变成自己的，有自己的写法，这个才是最应该追求的，就是“手中无剑，但心中有剑”。
5、其实还有第5档次，第5档次不用追求，它名字等于第1档次，仍然是“手中无剑，心中也无剑”，那是种超凡脱俗超然世外的心态，那就是不考。
其实我们都到现在了肯定是要考，要考就是要上战场，要上战场就得有剑。最好有自己的剑，实在不行再用我给的剑。这就是对我们背套句的态度。
二、提高作文分数，除了背套句，要有自己发挥的内容，需要背话题词、常见词
其实背诵还包括更多的东西，因为除了套句之外，毕竟有一些东西是要靠自己写的。套句再多也就占这个文章的1/3到1/2。只有极其个别的，比如说像休职信/辞职信，那可能模版句能占到80%到90%，可是这种东西它既然能够总结出这么多现成的模版，出题人是不太愿意出的。大家都可以背，背了就可以写得好，改卷人看着那么多一样的卷子他不好打分，所以考的可能性不是那么大。那么更多的具备可考性的作文是没有那么多模版可以背的，毕竟要有自己写的地方。那么改卷的人，尤其是比较熟练的改卷的人，他就不看你的模版句了，你背对了也没有太大的用处，只不过比你写错了要强一点儿。他真正看的是你自己写的地方怎么样。
