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.

C. At home. D. In the company.

4. Whose the owner of the Internet?

A. The headmaster. B. The officer.

C. The user. D. No one.

5. What does the writer try to tell us with the last two sentences?

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.

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
