This cartoon depicts an ironic scene: a man is walking dangerously on a wire with a pole in his hand. On one end of the pole hangs a box which is named "the convenience of jobs" while on the other end hangs a box which is labelled"illegal profits". The man is trying hard to reach the end of the wire, where a piece of papar is attached which says "you should be responsible for what you have done. " However, the man believes that he will not be blamed since he has taken just a little. The sobering aspect of this cartoon is corruption always happens on those who think they are the lucky ones.
Human nature being what it is, most people have a kind of fluke mind that they may not be punished since the amount they take illegally is small. However, this idea could not be more wrong in our contemporary society. Let's assume that all the government officials in China hold this idea. If this assumption comes true, it will definitely exert a butterfly effect: the appetite of these officials will become even bigger. The amount of money they take may end up as astronomical figures. One day their behavior will be revealed as severe crime and they will spend the rest of their lives in jail.
So it can be justified without any exaggeration that when we look at the consequences of curruption, we may find it very difficult to assess the costs. But these costs can be very considerable and may even hurl the whole society system into a chaos.It occurs to many that the most effective solution is to appeal to the authorities, or to take legal means. But that is just a passive wayand only works on extreme cases. Therefore, I recommend that massive media, school education and family cultivation should be activated to call for self-discipline on this matter.

In the pictures above are a father and her beloved son. In the left cartoon, smoking a cigarette and sitting in a sofa comfortably, the father is watching a football match on TV and shouting, “Son, study hard for me!” On the contrary, in the left portrayal, at 9 p.m. , the father is studying together with his son, both totally absorbed in their books. The caption indicates, “Instead of merely making a request, setting an example.”
The purpose of the pictures is to show us that utmost significance should be attached to practicing what you preach. On the one hand, parents teach much more by their actions, than by their words. Some of them may say to their children, “don’t say nasty things about so and so”, and then the children will hear them criticize their friends and neighbors. On the other hand, parenting is such a crucial responsibility, yet there are no required courses to prepare one to undertake this role in life. The only learning is the example from one’s own parents.
To sum up, parents are the best teachers.
Obviously, if parents’ actions don’t conflict their own words, they would have the opportunity to be outstanding examples of their children. Just as an old saying goes, “Action speak louder than words.”

This bar chart indicates different market shares of automobiles of three types of brand affiliations between 2008 and 2009.
In 2008，cars with Japanese brands topped the three types of vehicles，accounting for 35% of the total market. What follows is the cars with Chinese brands，hitting 25% of the auto market，with the share of American brand bottomed out at 15%. In 2009，some developments are noticeable in that the cars with the largest share became those of Chinese brands，which occupied roughly 32% of the market，while cars with Japanese and American brands took 25% and 15% of the whole market respectively.
It is observed that between 2008 and 2009，cars of Chinese and Japanese brands took turns to be the No.1 in terms of market share while those with American brands ranked the last in both years. And the share of Chinese-brand cars witnessed a mild increase and that of the Japanese-brand cars saw a moderate decrease，while the American-brand cars stayed the same.
From this graph，we can come to the safe conclusion that the Chinese automakers are doing a good job in outcompeting their Japanese and American counterparts in 2009，but the gap is not so significant and if no efforts were made from the part of the Chinese auto industry，the distribution map might be rewritten in the future.

These two drawings, apparently, can be associated with two distinct habits. In the left one, there is a girl beside a desk, being absorbed in learning, with an idea in her mind —it is advisable to complete as early as possible. By contrast, in the right picture, a young guy sits leisurely in a sofa, telling himself, “I need not act until the deadline.” Finally, two Chinese characters can be noticed, which say “habit”.
Successful figures are usually characterized by their diverse merits, including diligence, perseverance and striving every day. However, in reality, a host of youngsters are accustomed to taking no action until the last day. This terrible habit is particularly worth concerning and as a matter of fact, their laziness has constituted an obstacle that hinders their personal growth and progress.
To my understanding, we are supposed to accomplish our assignments on time each day. This good habit can be likened to a journey, leading to success and a promising future. A case in point is myself. During the past year, as a senior who has been preparing for the national entrance examination for postgraduates, I have never postponed one day’s task until the next day. This excellent habit ensures my motivation for learning, brings me power and helps me accumulate knowledge every day.
To conclude, never put off till tomorrow what you can do today. Meanwhile, every one should bear in mind that a positive habit means a lifelong treasure.

This pie chart clearly illustrates the purposes of students’ touring in a certain university. As is reflected by the diagram, 37 percent of college students travel in a bid to appreciating the scenery, next comes the aim of relieving pressure, accounting for 33% percent. By contrast, the percentage of students travelling aiming at others, making friends and cultivating independence account for 15%, 9% and 6% respectively.
Several primary factors could contribute to this phenomenon. In the first place, travel can offer us a wide range of experiences. In travelling, we may join tourists marveling at the incredible power of Niagara Falls, mingle with the happy throngs strolling in the Paris boulevards and experience the bitterness and joy of people on different lands and in different times. In the second place, college students, who have to juggle academic work, romantic relationships and a busy social calendar, are particularly susceptible to pressure. By touring, they can successfully manage and reduce stress.
Taking all these factors into consideration, we may predict that with the quickening pace of campus life and ever-increasing pressure, the number of university students touring will keep growing in the forthcoming decade.

From the picture above，we can see a spical "hotpot"，which contains many unique ingredients，stand for "LAO SHE"，"KONG FU"，"Decompostion" and some things to that effect.At the bottom of the picture，a sentence stands there extremely prominent，which can be brielf interpreted by this way：culture "hotpot" is not only good tasting but also strongly good for one`s health. A bit exggerating picture is，however，through careful observation，we may discover that behind this strange senario，what the cartoonist intends to show us is extremely obvious：the significance of integration between Chinese culture and other countries` culture.
With the implementation of the China`s reform and opening up，an emerging tendency is that more and more foriegners are getting fascinated with our Chinese culture.They come to China to learn Chinese language，taste delicious Chinese foods，make friends with Chinese people，and etc.All these make them pretty comfortable and agreeable.At the same time，however，this phenomenon also stirred a heated dated in our society，so，how to render the other countries` culture be more compatible with our Chinese culture has caused wide public concern.
As far as I am concerned，before giving my opinion I think we should take closely look at the culture`s function widely.Policymakers should be more aware of that culture integration not only benefits to our making a further development but exerts a great contribution to the world peace.
考研英语优秀作文 篇7
For over a decade, the craze of Chinese college graduates taking qualifying examinations to become civil servants has remained unabated. An important proportion of graduates view civil service as their top priority in job selection and they spare no efforts in preparing for those examinations, sometimes years before their graduation.
To some extent, this craze is a modern revival of the ancient notion that “those who excel in academics end up in officialdom.” In the present-day China, however, there are complicated reasons underlying this phenomenon. The jobs in sectors other than civil service are insecure and unstable, and employees have to work under greater stress faced with growing competitions in the workplace and the industry. Some government departments are related to monopolized industries and civil servants can enjoy unusually high salaries and welfare benefits. Finally, government officials are usually regarded as occupying the highest rung of the social hierarchy and a student who succeeds in becoming government official is considered the pride of the family, adding prestige and glory to the entire clan.
For all the apparent attractions of the officialdom, the craze of entering the civil service is a distorted one. In the United States, truly ambitious students enter the industry instead of civil departments, where they apply their individual initiative to achieve personal success. It has already been pointed out that, with so many best minds of the nation fighting their way into the civil sectors, the consequences are catastrophic. The civil servants system, with its inherent bureaucracy and rigid rules, would inevitably turn the otherwise energetic and aggressive young people into docile followers of their superiors’ instructions and dutiful but mediocre implementers of executive orders. This will considerably undermine the vitality of a whole generation and the competitiveness of the entire country in the international arena. All forms of craze are accompanied by elements of irrationality and abnormality and, the sooner this craze vanishes, the better.

To Respect the Old and Love the Young.
How impressive the set of pictures are! In the first picture, the mother takes the daughter by the hand, while after thirty years the daughter hold her mother’s hand which is depicted in the second picture.
The meaning conveyed in the two pictures reveals that to respect the old and love the young is the traditional virtue and should be passed on from one generation to another. In real life, our parents not only give us life but do much in bringing us up. As the time goes on, they grow so physically weak that they no longer have the power to support themselves. So it is human nature for us to take our responsibility of taking care of them when they are old. Meanwhile, the virtue of willing to support the graying parents should be educated among Chinese people, no matter how young they are. It is necessary to drill the idea to the young all the time, so that they can better respect the older in future.
With love for the young, our society will be full of sunshine; with respect for the old, our country will be harmony and prosperous.

How concise but thought-provoking the picture is! What is clearly depicted in the picture is that a boy,sitting in front of a computer, is selecting courses through the system of selecting courses, who takes a considerable number of factors into consideration ,which include the emphasis of innovation, the updating of knowledge and the level of difficulty as well as the scoring, the qualified rate and burden of assignment. Apparently，it is how to make the best courses for college students that is what the author intends to convey to us.
It is not uncommon to find that with the development of society and economy,the competition is becoming increasingly intense and the updating of knowledge is getting quicker and quicker.Though some courses are easy to learn and get high scores，it may be out of date.In addition ，it has been universally acknowledged that the awareness of innovation will not only be beneficial to our personal growth and success but also contribute to the development and progress of society and economy ，which is the most essential qualification that anyone who wants
to achieve success should possess.Consequently ，the courses stressing innovation should be chosen.Furthermore, the way to success is full of obstacles and hardships. Anyone who is eager to get successful must realize that there is no shortcut to success at all because all achievements come from laborious trial and effort. Accordingly ，young students are supposed to choose some courses with great difficulties to improve their abilities.
After what we have discussed above，we can reasonably come to the conclusion that whatever the prospect is，however difficult the situation is，we ，young students ，should have the courage to face difficulties ，be willing to absorb new knowledge and cultivate the consciousness of innovation.I am strongly convinced that only by doing so,can our promising future be guaranteed.

Write a letter to your university canteen, making suggestions for improving its service. You should write about 100 words on ANSWER SHEET . Dear Sir or Madam, I am a student of our university, who often have meals in our canteen. Generally speaking, our canteen provides quite good food.
However, I still have some suggestions for you to make our canteen more popular among students. To begin with, I wonder whether you could provide more varieties of food. We do not have many options when eating in our canteen now. To continue, some students have complained about the price of the food there, would you please lower it down? I do hope to have a better canteen. And I would be highly grateful if you could take my suggestions into consideration.
考研英语优秀作文 篇11
As is vividly depicted in the picture, many young people are standing together when they find that there are so many ways to go.Thus,all of them are stopping there and waiting for help. Obviously, it is the shortage of confidence for their future that makes it impossible for them to get the attainment they want to.
Simple as it is, what the picture conveys to us is thought-provoking. With the development of economy and society, competition is increasingly fierce and there are more and more chance for us to get. But it is impossible for the ones to achieve attainments if the ones have no striving spirit to surmount the difficulties. Hence, people in mounting numbers put great emphasis on the striving spirit. In fact, it has been universally acknowledged that the ability of fighting is the most essential qualification that anyone who wants to achieve success should possess.
To my way of thinking,the problem that all of the college are just stopping and waiting but no fighting and thinking will generate severe consequences .Measures should be adopted before things get worse. It is high time that all of us ,parents, educators,and the authorities, make combined efforts to make young people change their outlook of life and acquire determined spirit. Only by this way is it reasonable for us to believe that this problem can be perfectly solved in the near future.
考研英语优秀作文 篇12
In the cartoon we see a servant bringing a cup of coffee for the emperor. The joke is that the idea of emperor and the idea of coffee do not usually come together. It is funny to think of the emperor drinking coffee. But the cartoon may yet have another meaning. It implies that emperor, if he were still there today, would learn to drink coffee. Modernization is a historical trend.
China is a country with a long history. It has special traditions and customs. They are the nation’s great treasures which we should do our best to preserve. However, as China opens up to the world, more and more foreign ideas and products come into country. How we take this western influence and what relationship should be established between the east and the west have become urgent questions for us to answer. For example, should we allow a coffee shop to be opened in the Forbidden City, a place which is thought to represent the essence of oriental life? Can the coffee shop integrate itself into the surrounding or will it from an eyesore?
I believe that we should be open-minded about western influence. If it is good, we should not refuse it. A coffee shop in the Forbidden City will not pose an threat to our traditional culture. It will instead provide a convenient resting place for visitors who have to walk through the huge palace. The spirit of the 21st century is one of cooperation and coexistence. We should allow different cultures to exist together and flourish together.

This picture is simple but significant. As is shown in the picture above, rising up his head, a young boy is holding a glorious sun with his firm hand. The caption indicates that, “ with dreams, our hearts can fly high; with flight, our dreams will not be far away.”
Why are dreams so importantWe may attribute its significance to three factors. First and foremost, dreams can give us courage and strength to overcome all the difficulties in our lives. Besides, having dreams is beneficial for us to be confident, passionate and energetic, and it may put us in a favorable position in our life journey. On the contrary, were there no dreams, our life will be dull and meaningless. Last but not least, if all of us have dreams, our society will be more vigorous and harmonious.
Considering every aspect of this positive issue, we should bear in mind that dreams are of great significance to both our society and ourselves.Therefore, the mass media, such as television, Internet and radio, should try best to propaganda and advocate it. As for ourselves, we should take practical actions to cherish our precious dreams and let them be realized. Then, we have every reason to be convinced that we can have a bright future if we have dreams.

The bar chart clearly indicates the turnover of online shopping and its growth rate in China from 2001 to 2008. During that period, there was a dramatic increase from 0.6 billion to 125 billion in its turnover. Meanwhile, the growth rate decreased from 200% to 110.4% at the same time.
Why dose this phenomenon take placeThere are generally three factors accounting for it. First and foremost, due to the fast economic and social development, people enjoy a sharp improvement in their living standards. Accordingly, they can afford to buy computers and mobile phones: the common tools for shopping online. Besides, e-shopping is extremely convenient and efficient. It is available 7/24 and this means people can buy what they want anytime without going out. Last but not least, the price of the goods online is much lower than those in the stores, which greatly caters to the consumer’s needs.
From what has been discussed above, we can predict that the turnover of online shopping will continue to increase at an alarming rate and it will give a huge boost to our national economy. However, we should also be aware of its drawbacks, such as fake commodities, personal financial security, illegal ads and so on. Thereby, we should take a reasonable and scientific attitude towards it.

This picture is really thought provoking. As is vividly shown in the above picture, a book is lying above the grass and beautiful flowers. Beside it, there is a topic thatsays:“reading”. There is no denying that the picture implies that reading is of utmost importance to us.
Considering every aspect of it, we may attribute its significance to three factors. First of all, reading can broaden our horizon, widen our knowledge and eich our experience. Besides, reading is to success what water is to a fish. It can put us in a favorable position in the job market. Last but not least, if all of us are willing to read more and extensively, our society will be more progressive and prosperous.
From what has been discussed above, we may safely draw a conclusion that reading is indispensable in our daily life. Therefore, the mass media, such as
television, Internet and radio, should try best to propaganda and advocate it. As
for ourselves, we should take practical actions to enhance our awareness of reading. Then, we have every reason to be convinced that we can have a bright future and a beautiful world.

In the black and white drawing above, a youth gravely contemplates a narrow winding path heading into a forest. Perhaps he thinks that his own future may be much like this path; full of bends and curves, thorns and traps. The road to success is never anything but uneven and difficult.
In fact, one could even say that the more successful one's life is, the more problems and hardships one must have overcome. The ability to work through difficult situations and unfortunate events only makes one stronger and more capable. Given that the road to happiness always contains obstacles and setbacks, we should be well prepared for the hardships that life inevitably brings, and abandon the idea that life is smooth or easy. We must accept the fact that failures are unavoidable, whether they are failures in examinations, in finding a job, or carrying out a task. People who accept that their life will not always be simple or calm are better able to handle problems when they arise. Those who are upset by each and every small setback — and there are many people with such attitudes— do not have much potential. Failure is mother to success as it can strengthen one's will. Those who can draw lessons from failure are destined for success.
考研英语优秀作文 篇17
It is everyone's wish to have things go their way. Yet the journey throughlife is not always the case and we should be prepared for the twists and turns it offers us. This is certainly the case as shown in the cartoon.
Twists and turns are a part of life and setbacks often happen. For many reasons, we often have to encounter failure in a complex society. No one can avoid or escape these unexpected changes in our daily lives; however, failure may be aroute toward success. This causes us to reflect about what happened and as a result we build up and accumulate experience. We are then more likely to come up with a possible solution, and so twists and turns can turn into treasures. Edison,for instance, the inventor of the electric light bulb, made hundreds of models that failed before he came up with the right one. In general it is failure that encourages us to work harder which eventually leads to success.
Twists and turns in life are unavoidable and are not always bad. We should have a more optimistic view on life and try to make the most of it and draw lessons from the bumps and turns ゛long the way.

October 24 is Union Nations Day. This day is noted in the calendars, but not observed as aholiday around the world. I want the entire world to celebrate the birth of the United Nationsbecause of its attempts to promote peace, education, and health around the world.
Peace is the most important thing that we can have today. The sooner that we can stop war thesooner we can all have better lives. There are countries around the world that have been at warfor generations. In some of these countries, UN Peacekeepers have temporarily stopped theviolence so people can go about their lives. If this peace could be made lasting, the lives ofthese citizens would be much richer.
The UN actively works to promote education. Universal literacy is one of its important goals.Every child in the world deserves to know how to read and write. The UN is also involved in jobtraining for adults. The age of information technology demands new job skills. The UN workswith continuing education programs around the world so workers are not left out of the jobmarket.
The UN has played an instrumental role in the eradication of smallpox. Polio vaccines andAIDS-awareness programs have also helped reduce the incidence of these diseases. There isa lot to be done in these areas.
Much of the work of the UN is unknown and underappreciated. If we want to live in a peacefulworld, where every child can attend school and where every citizen has access to health care, weneed to support the work of the UN. We need to recognize its importance and celebrate itsbirthday.

As is vividly depicted in the picture, in the first picture there are a lot of books besides a boy, but he doesn’t read any of them. By contrast, the second one portrays that another boy makes a plan of reading: 20 books one year. In fact, the phenomenon in the picture doesn’t surprise us at all. Simple as it is, the intended meaning of the picture is worth our reflecting.
Undoubtedly, the cartoonistaims at reminding us of the significance of readingand knowledge . At the top of the list, we should attach importance to reading mainly due to that it can enable us to ameliorate ourselves so we can bequalified for future career promotion, and be ready for meeting the forthcoming challenges.What’s more, we ought to place a high value on the role played by knowledge in personal growth. Put it another way, in this ever-changing world, knowledge accumulation is to personal growth what water is to fish. To sum up, if reading and knowledge missour attention in any possible way, we will suffer a great loss beyond imagination.
Hence, it is vital for us to derive positive implications from the above picture. For one thing, we should frequently use it to enlighten the young. For another, we should cultivate the awareness of teenagersthat reading isvery vital. Only by doing so,can we become winner in the face of difficulties.
考研英语优秀作文 篇20
I see two kinds of pressure working on college students today: economic pressure, parental pressure. It is easy to look around for rebels-- to blame the colleges for charging too much money, the parents for pushing their children too far. But there are no rebels, only victims.
The pressure is heavy on students who just want to graduate and get a job. If I were an employer I would rather employ graduates who have this range and curiosity than those who narrowly pursued safe subjects and high grades. I know incalculable students whose inquiring minds cheer me. I like to hear the play of their ideas. I don't know if they are getting A or C, and I don't care. I also like them as people. The country needs them, and they will find satisfying jobs. I tell them to relax. They can't.
Nor can I blame them. They live in a brutal economy.Today it is not unusual for a student, even if he works part time at college and full time during the summer, to increase to 5, 000 in loans after graduation. Encouraged at commencemerit to go forth into the world, he is already behind as he goes forth. How could he not feel under pressure throughout college to prepare for this day of reckoning?
Along with economic pressure goes parental pressure.Inevitably, the two are deeply integrated.
Poor students! They are caught in one of the oldest webs of love and duty and guilt. The parents mean well: they are trying to steer their sons and daughters toward a secure future. But the sons and daughters want to major in history or classics or philosophy-- subjects with no "practical" value.Where's the payoff on the humanities? It's not easy to persuade such loving parents that the humanities do indeed pay off. The intellectual faculties developed by studying subjects like history and classics are just the faculties that make creative leaders in business or almost any general field.
Luckily for me, most of them got into their field by an indirect route, to their surprise, after many roundabout ways.The students are startled. They can hardly conceive of a career that was not preplanned. They can hardly imagine allowing the hand of God or chance to nudge them down some unforeseen trail.
考研英语优秀作文 篇21
THE dollar s tumble this week was attended by predictable shrieks from the markets; but as it fell to a 20 month low of $1.32 against the euro, the only real surprise was that it had not slipped sooner. Indeed, there are good reasons to expect its slide to continue, dragging it below the record low of $1.36 against the euro that it hit in December 2004.
The recent decline was triggered by nasty news about the American economy. New figures this week suggested that the housing market s troubles are having a wider impact on the economy. Consumer confidence and durable goods orders both fell more sharply than expected. In contrast, German business confidence has risen to a 15 year high. There are also mounting concerns that central banks in China and elsewhere, which have been piling up dollars assiduously for years, may start selling.
Yet cyclical factors only partly explain why the dollar has been strong. At bottom, its attractiveness is based more on structural factors-or, more accurately, on an illusion about structural differences between the American and European economies.
The main reason for the dollar s strength has been the widespread belief that the American economy vastly outperformed the world s other rich country economies in recent years. But the figures do not support the hype. Sure, America s GDP growth has been faster than Europe s, but that is mostly because its population has grown more quickly too. Dig deeper and the difference shrinks. Official figures of productivity growth, which should in theory be an important factor driving currency movements, exaggerate America s lead. If the two are measured on a comparable basis, productivity growth over the past decade has been almost the same in the euro area as it has in America. Even more important, the latest figures suggest that, whereas productivity growth is now slowing in America, it is accelerating in the euro zone.

Vividly depicted in the cartoon is a race of humans on a social network that are isolated in their own little cubicles. They are all sitting in front of their computers， connected to each other through the Internet and their devoted looks and postures showed their addiction to the Internet.
This cartoon， I believe， intends to draw our attentions to the negative effects the Internet has brought to our daily life as it brings in some benefits， such as easy access to information， instant communication with people from afar and cheap cost of communication. The more people are hooked to the Net， the more isolated they are from the real world. Since people can easily pretend their identities on the Internet， everything online becomes illusive and untrustworthy. The Internet， which was intended to bring people closer to each other， in effect prevents people from making real acquaintances that one can make with a casual exchange of greetings and eye-contact in a face-to-face communication.
Serious consequences， such as fear of real-time interactions， online cheating or blackmailing， may follow if the use of the Internet is not brought under systematic control. I strongly suggest that people only use the Internet for necessary business transactions and personal contacts with those they have already known face to face.
考研英语优秀作文 篇23
Bacteria are extremely small living things. while we measure our own sizes in inches or centimeters, bacterial size is measured in microns. one micron is a thousandth of a millimeter: a pinhead is about a millimeter across.
Rod-shaped bacteria are usually from two to four microns long, while rounded ones are generally one micron in diameter. thus if you enlarged a rounded bacterium a thousand times, it would be just about the size of a pinhead. an adult human magnified by the same amount would be over a mile(1.6 kilometer) tall.
even with an ordinary microscope, you must look closely to see bacteria. using a magnification of 100 times, one finds that bacteria are barely visible as tiny rods or dots. one cannot make out anything of their structure.
using special stains, one can see that some bacteria have attached to them wavy-looking "hairs" called flagella. others have only one flagellum. the flagella rotate, pushing the bacteria through the water. many bacteria lack flagella and cannot move about by their own power, while others can glide along over surfaces by some little-understood mechanism.
From the bacteria point of view, the world is a very different place from what it is to humans. to a bacterium water is as thick as molasses is to us. bacteria are so small that they are influenced by the movements of the chemical molecules around them. bacteria under the microscope, even those with no flagella, often bounce about in the water.
This is because they collide with the watery molecules and are pushed this way and that. molecules move so rapidly that within a tenth of a second the molecules around a bacteria have all been replaced by new ones; even bacteria without flagella are thus constantly exposed to a changing environment.
