Summer reading book

I read ”cry“, is read ”Kong Yi a few“. Although previously read this article, but in ”the scream“ to create the atmosphere of, the sad and ridiculous Kong Yi few as if was added to the many tragic color.

Talking about Kong Yi, I think of China's education. At the end of Qing Dynasty, some people read the ”heavy emperor Kennedy, the name of Er Cao. Wanban are Xiapin, only high school, “” child prodigy poetry, reveals a “Scholar” glorious; some people read is “chaos, muddy coagulation and” of “young school Qiong Lin”, to teach the ancient cliche. These so-called “textbook”, I really do not know how many times change.

And it is said to reduce the burden on students, the reason why said, it is said, it is because it does not seem to affect me. But to eat lunch, brother, sister, who seems to be benefited, just understand that the junior high school students is beyond the student category. At this point, once again, a few of the arguments: “reading a book about people......” Actually relieved a lot of.

After dinner, which asked: “this year summer vacation homework?” I stood up and looked at the unfinished work, shaking his head, said: “not much less! Enough? Not much also.”

Today is the number 11, a few days to go to school classes. This afternoon I from the neighborhood kids with a few hands back a lollipop novel “a thing”. In the novel the “I” for the first time see the driver, the noble qualities of a common laborer, in the heart although is in serious consideration and reflection. However, when the police came. “I had to catch a handful of copper gave him.” I have found that their small, can put yourself in the position to judge? The driver's behavior and whether they can use the money to weigh? Moreover, one can solve the problem of copper, wash away his mistake? Nature can't, and “I” can't answer myself “.

Love of money often believe in money however is the ”God of wealth“ in ”the legend of the God of wealth“ in say: ”hard work and honesty is not money can buy of.“ Those who think that money is everything, everything in terms of money always claim to be a wise man, Mr. Lu Xun said: ”world but by April Fool's cause, smart people will not support world...“ Advise those who listen to ”God of wealth“!

Reading, not only eich the knowledge, but also to make people understand the philosophy of life.

The Farm

Listen to others to say, in the happy farm vegetables is fun, I want to go there on a piece of land to grow vegetables.

Saturday, my mother helped me to apply for a QQ number, opened its own farm. Just started, I'm just a 0.

School, my mother said to me: ”you have to take care of the farm to give you, you can only play once on Saturday.“ I said, ”okay.“.”

On Saturday, after my mother's approval, I entered my farm, I saw that I had been raised to level 3, and there were more than 5000 gold coins. Even more delightful is that my geography “food” has matured. I stretched out my hand, “key removal” soon after picking “food.”.

At this time, I click next to the “QQ friends”“. Friends ”boards“ and ”papaya“ mature, a yellow, very lovely, I'd steal some. At this time, I found a sign on the side of the ”labor is glorious, stealing shame“. It suddenly dawned on me that it was wrong to steal other people's things. But the stolen papaya had entered the ”warehouse“, I can't get it out. How to do? Let me do something for her. I picked up the herbicide to help her weed, but also used pesticides to help her kill the ”dish“ leaves on the pests.

After all these things, I went back to my farm. Pick up the shovel to shovel dirt, and then go to the store to buy seeds. ”Store“ of the seed lot, with radish seeds, potato seeds, and watermelon seeds. I bought a radish seed planted in the ground, and then poured some water, and so on tomorrow, the flowering.

Tell you, because every Saturday to adhere to the ”farm“ hard work, I have now risen to 17.

In the QQ farm vegetables, ”the farm“ let me know, ”Yifengengyun, a harvest, wealth to own hard work to create, steal other people's things are shameful.

People all over the world today are beginning to hear and learn more and more about the problem of pollution. Pollution is caused either by man’s release of completely new and often artificial substances into the environment, or by releasing greatly increased amounts of a natural substance, such as oil from oil tankers into the sea.

The whole industrial process which makes many of the goods and machines we need and use in our daily lives, is bound to create a number of waste products which upset the environmental balance, or the ecological balance as it is also known. Many of these waste products can be prevented or disposed of sensibly, but clearly while more and more new and complex goods are produced there will be new, dangerous wastes to be disposed of, for example, the waste products from nuclear power stations. Many people, therefore, see pollution as only part of a larger and more complex problem, that is, the whole process of industrial production and consumption of goods.

Others again see the problem mainly in connection with agriculture, where new methods are helping farmers grow more and more on their land to feed our ever-increasing populations. However, the land itself if gradually becoming worn out as it is being used, in some cases, too heavily, and artificial fertilizers cannot restore the balance.

Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is a great waste of resources, in terms of glass, metals and paper. Advertising has helped this process by persuading many of us not only to buy things we neither want nor need, but also to throw away much of what we do buy.

Pollution and waste combine to be a problem everyone can help to solve by

cutting out unnecessary buying, excess consumption and careless disposal of the products we use in our daily lives.

With the improvement of our living standard, more and more people can afford a car. As a result, our roads are more often than not crammed with cars. However, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. So nowadays we advocate to lead a low-carbon life.

My suggestion is we should ride bikes more often instead of driving riding a bike, we can not only exercise our body but also protect our environment. Why not have a try, my dear friends?

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40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。

一、写作导航

说明文是以说明为主要表达方式,用简洁明了的文字介绍事物、解释事理的文章。它是一种应用性很强的文体。凡是对事物的类别、性质、特征、状态、功能等进行解释,以及对事物的发生、发展、消亡过程进行解说的文章,都属于说明文。说明的目的是让读者有所知,给读者提供知识,使之了解客观世界,掌握问题的解决办法。说明文的基本特点就是具有知识性、科学性、应用性、解说性、条理性。常见的说明文有:解说词、说明书、书文简介、科普小品、内容提要等,它们或者用来介绍人物,或者用来介绍事物,或者用来解释概念,或者用来解说论据。

说明文常用现在时,但有时也会用到过去时,将来时等其它时态。

1. 人物介绍

简要地介绍某个人的情况,叫做人物介绍。随着社会的发展,人们对信息的输出和输入愈来愈重视。在学习、工作和生活中,常要介绍自己、推销自己或宣传他人,都要作人物介绍。写人物介绍,首先要全面了解这个人,然后根据目的的需要选写内容,简明扼要而突出重点地介绍,力求真实准确,恰如其分。

1) 出生年月 2)主要经历 3)事迹成就 4)影响、评价

2. 物体、地点介绍

对于地点的介绍,常采用地点的空间方位作为介绍的顺序。它能把复杂的地理位置,通过分层说明,详尽而有条理地解说清楚明白,给读者一个具体的位置,清晰的印象。

根据说明地点的结构特点、介绍顺序一般有定位观察顺序和移位观察顺序。

远远的地平线在蒙蒙的雾气里渐渐模糊起来了;旷野仿佛也一下子凝重了许多。

熏青色的远山,宛然一艘搁浅的船。此情此景,不能不让人回忆起什么。

回忆什么呢?

于是,那赶也不走,挥也不去的往事记忆在我的脑海里渐渐清晰起来,是二年前那个蒙蒙的下午……

那时我五年级,放学回家的路上踢着一个小石子,一不小心跌倒了,腿上划了一块薄薄的皮,疼的我哭起来了,我一步步小心的走回家。回家便大哭起来。当时,无意中发现妈妈对我漠不关心,平和地对我说:“男子汉!哭什么象个娘娘腔似的。”他就匆匆地离开了。难道我不是她亲生的?一刹时,我的心空落落的,只大哭起来,甚至还大喊起来:“妈妈不要我了,妈妈不喜欢我了。”

爸爸来哄我。

我继续大哭。我不信妈妈能这样不管我的死活。我边哭边看,就在她走到胡同尽头该转弯的时候,她突然站住回头一看,我那时幼小的心灵不知不觉为什么刹时一顿,我愣了,只觉得眼睛热热的,腿也不痛了……

六年的时光已经遥远得无可企及了,但是,如今不知为什么,一个人独坐是我常常想起妈妈那近乎轻描淡写的一看,常常忍不住泪流满面。

是啊!那看似极平凡的一个动作,却充满了妈妈无言的爱深沉的爱呵。

有谁的爱能比这更深呢?

妈妈无言的一看啊,我灵魂深处一道美丽的风景……

英语说明文写作技巧

1.罗列法(listing)

在文章开始时提出需要说明的东西和观点,然后常用first,second,…and finally加以罗列说明。罗列法广泛地使用于各类指导性的说明文之中,下面这篇学生作文就是用罗列法写成的:

Early Rising

Early rising (早起) is helpful in more than one way. First, it helps to keep us fit (健康)。 We all need fresh air. But air is never so fresh as early in the morning. Besides, we can do good to our health from doing morning exercise (做早操)。

Secondly, early rising helps us in our studies. We learn more quickly in the morning, and find it easier to remember what we learn in the morning.

Thirdly, early rising enables (使能够) us to plan the work of the day. We cannot work well without a good plan. Just as the plan for the year should be made in the spring, so the plan for the day should be made in the morning.

Fourthly, early rising gives us enough time to get ready for our work, such as to wash our faces and hands and eat our breakfast properly.

Late risers may find it very difficult to form the habit of early rising. They ought to make special efforts to do so. As the English proverb says,“Early to bed and early to rise, makes a man healthy, wealthy and wise.”

罗列法经常用下列句式展开段落,我们可以注意模仿学习:

There are several good reasons why we should learn a foreign language. First of all, …Secondly, …And finally, …

We should try our best to plant more trees for several good reasons First of all, …Secondly, …And finally,

必须指出的是,有时罗列法并不一定有明确的first, second…等词,但文章还是以罗列论据展开的。

2.举例法(examples)

举例法是用具体的例子来说明我们要表达的意思,常用for example, for instance, still another example is…等词语引出。下面这篇学生作文就是用举例法写成的:

Recreation

It is impossible to keep in good health unless we take enough recreation (娱乐)。 The mind, too, needs change to make it fresh and vigorous (有活力的) There is much truth in the old saying, All work and no play makes Jack a dull boy.“

There are many games which boys and girls can play after their school work is done, for instance, football, tennis, and kite-flying. Other examples of recreation are boating, fishing, gardening, cycling, walking, chess-playing, and reading. Persons who sit much at their business should take a kind of recreation that will supply their muscles (肌肉) with exercise. Those who spend most of their time in the open air and do manual work (体力活) should adopt (采纳) reading or some other quiet form of recreation.

Cycling is said to be an important means of recreation, but many persons foolishly tire out themselves by cycling too much. The same may be said in regard to football. Tennis is a pleasant form of recreation. Many persons take great delight in boating. Fishing requires much patience, and there is much danger of taking cold by sitting still on a cold day too long. A good brisk (轻松) walk is one of the finest forms of exercise. For persons engaged in outdoor labor, chess-playing is another excellent form of recreation.

可以看出,举例法和罗列法有时可以结合使用:即用罗列法来列出例子,用例子充实罗列的说明。

3.比较法(comparison and contrast)

比较法是对两个对象进行比较,从而进行说明的写作手法。比较法又可细分为比较相同点(comparison)和比较不同点(contrast)两种方法,比如:

From Paragraph to Essay

Although they are different in length (长度), the paragraph and the essay are quite similar in structure (结构)。 For example, the paragraph starts with either a topic sentence (主题句) or a topic introducer followed by a topic sentence. In the essay, the first paragraph sets up the topic focus (主题所在) Next, the sentences in the body of a paragraph develop the topic sentence. Similarly, the body of an essay consists of a number of paragraphs that discuss and support the ideas given in the introductory (引导的) paragraph. Finally, a concluding sentence (结束句) ——whether a restatement, conclusion, or observation——ends the paragraph. The essay, too, has a concluding paragraph which ends the essay logically and satisfactorily. Although there are some exceptions (例外), most well written expository (说明文的) paragraphs and essays are similar in structure.

可以看出,在比较相同点的时候,常用到similarly,also,too,in the same case,in spite of the difference等这样的词语。

European Football and American Football

Although European football is the parent of American football, the two games show several major differences. European football, sometimes called association football or soccer, is played in 80 countries, making it the most widely played sport in the world. American football, on the other hand, is popular only in North America (the United States and Canada)。 Soccer is played by eleven players with a round ball. Football, also played by eleven players in somewhat different positions (位置) on the field, is played with an elongated (拉长的') round ball. Soccer has little body contact (接触) between players and therefore needs no special protective equipment. Football, in which players make the greatest use of body contact to stop a running ball-carrier and his teammates, needs special protective equipment. In soccer, the ball is advanced toward the goal by kicking it or by butting (顶) it with the head. In American football, on the other hand, the ball is passed from hand to hand or carried in the hands across the opponent's (对手) goal. These are just a few of the features which distinguish (区别) association and American football.

这是一篇用比较不同点的手法写的说明文。从文章中可以看出:however,on the other hand,in contrast,but,nevertheless等表示转折的词语常用来引导对不同点的比较。

4.定义法(definition)

定义法也是英语说明文中常用的写作手法,特别是在对具体事物概念进行说明时经常使用。定义法的基本要素是定义句。英语中常见定义句的模式是:

被定义对象is所属类别+限制性定语

可以看出,定义句中限制性定语越详细,定义就越精确,比如:

A bat is a small mouse-like animal that flies at night and feeds on(以……为食品)fruit and insects but is not a bird.

其实,在英—英词典中,对英语单词的英文解释就是定义法的典型例子。比如,看看Longman词典对student和teacher的定义是很有意思的:A student is a person who is studying at a place of education or training. A teacher is a person who gives knowledge or skill to sb. as a profession (专业)。

5.顺序法(sequence of time, space and process)

顺序法是指按时间、空间或过程的顺序进行说明的一种写作手法。比如按照时间顺序介绍一个科学家的生平,用空间顺序阐述逐渐开发西部的重要意义,用过程顺序法解释葡萄酒的生产过程等等。

Coal

Coal underwent (经受) many changes before it became the bright, brittle (脆的), black substance which we now use. During ancient times (在上古时代), when the earth enjoyed a very warm and wet climate, the land was covered with large forests and big plants. As time went on, the ground changed and began to sink (下沉) a little. These very large numbers of trees and vegetables received a deposit (沉淀) of sand and clay. This layer of sand and clay pressed upon the layer beneath and prevented it from contact with air. These trees and plants received the pres sure and changed its appearance.

Generations after generations (几世纪后), as the ground kept gradually sinking, another layer of sand and clay was again deposited (积聚) above the layers already formed. A great pressure was thus exerted (作用) and the peat (泥煤) was changed into the black and brittle substance which is known as coal.

Coal is a kind of mineral which is formed by nature as above stated. It is an important industrial material and is chiefly used as fuel. It is very valuable in the industrial world. The place where coal deposit is called a coal mine (煤矿)。 In China, coal mines are largely found in the north-west part of the country. Shanxi is a famous province for producing coal. It has the most coal of China.

6.分类法(classification)

分类法是将写作对象进行分类说明的一种写作手法。比如:著名的英国哲学家弗朗西斯·培根(Francis Bacon)在其脍炙人口的《谈读书》(Of Studies)一文中就用到了分类法:

Some books are to be tasted, others to be swallowed, and some few to be chewed and digested, that is, some books are to be read only in parts, others to be read, but not curiously, and some few to be read wholly, and with diligence and attention. Some books also may be read by deputy, and extracts made of them by others; but that would be only in the less important arguments, and the meaner sort of books…

I’m a 20—year—old boy, and the following is my story.

A month after I graduated from high school in August, , I was coming home from swim_practice in the training centre of the city and was involved in a car accident. I was so seriously injured that I was in a coma for more than two months at Prince Georges Hospital.

I suffered a lot from the experience of dying eight times during my coma and I couldn’t open my mouth to talk or to communicate when I eventually came around. At that time, it seemed that walking was never going to happen again due to all the extreme injuries. Just like my body, my dreams were completely destroyed. But I was not going to let my injuries stop me from realizing my dreams.

After receiving a total of 15 operations and 36 blood transfusions, I had to make every great effort to learn to talk, eat, walk, shower, and live on my own again. When I was out of hospital,_I still had to go to outpatient therapy in Waldorf, Maryland. After I spent a few months in a wheelchair,_I took baby steps to walk on my own. It was a miracle that I was able to walk again, but I still wanted to prove that I could not only walk, but also run.

When it came true, I wanted to get back into the pool again. After having a few lung tests, I was able to go in the pool a little bit each week. After a few months of swim training,_I began my freshman year at St. Mary’s College of Maryland and then became a proud member of the swim team.

By telling my story, I want to make a positive influence on the world. I am just trying to live dad push me round in my them and their family members. I wanted to let them know that everything was going to be okay. Somehow, things would work out for the best.

Honesty means speakingthe truth and being fair and upright in act。 He who lies and cheats is dishonest。: Those who gain fortunes not by hard labour but by other means is dishonest。 Honesty is a good virtue。 If you are honest all the time,you’ll be trusted and respected by others。

A liar is always looked down upon and regarded as a black sheep by the people around。 Once you lie, people will never believe you even if you speak the truth。 However, in the tide of commodity economy today, it seems that more and more people believe in money at the sacrifice of honesty。 To them, among such things as health, beauty, m6ney, intelligence, honesty, reputation and talent, honesty is the only thing that can be east away。 They don’t understand or pretend not to understand that honesty is the biggest fortune humans own, and that it is the prerequisite for doing everything well。 I think these people areto be pitied。 In short, honesty is gold。 Honest, your reputation will become great;dishonest, your name will be spoiled and your personality degraded。

Therefore, we should never make such an excuse as “A little dishonesty is only a trifle thing。 We should eradicate immediately the seed of dishonesty once it is sowed in our minds。

诚实意味着真理和公正和正直的行为。他谁的谎言和欺骗,是不诚实的。:那些获得不是通过辛勤劳动,而是通过其他方式的财富是诚实。诚实是一种美德。如果你是诚实的,你会赢得别人的信任和尊重。

一个说谎者总是看不起周围的人视为害群之马。一旦你的谎言,人们永远不会即使你说真话相信你。但是,在商品经济大潮的今天,似乎越来越多的人相信钱牺牲诚信。对他们来说,作为健康,这样的事情在美、钱、智慧、诚实、信誉和人才,诚实是可以东走。他们不明白或假装不明白诚信是人类自己的财富,这是做好事情的前提,我认为这些人值得同情总之,诚信是金。诚实,你的声誉将成为伟大的;已拒付筑巢,你的名字会被宠坏,你的人格退化。

因此,我们不应该让这样的借口是“有点不诚实只是一件小事,我们应该诚实的种子一旦播种在我们的脑海中立即消除。

才下过几阵蒙蒙的细雨,“秃头”的桃 树立刻冒出了圆球似的花骨朵儿,闭着眼做 着它的美梦。花骨朵儿渐渐长大,有的才展 开两三片花瓣儿,有的花瓣儿全展开了,露 出嫩黄的花蕊儿,有的还是花骨朵儿,看起 来饱胀得马上要破裂。远远望去,那沉甸甸、粉红的桃树像天边的云霞,走去看,就像一 个个小孩张着嘴巴冲我笑呢!桃花的美丽引 来了一个个小朋友,就连蝴蝶、蜜蜂也飞来 “看热闹”了。它们一只一只的在花丛中穿 来穿去,翩翩起舞。

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。

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.

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。
