Work as a Part of Life
Some people regard work as the goal of life and spare no pains to pursue a fulfilling career. Others regard work as a means to achieve the value of life, emphasizing the meaning and significance of life itself. I think work is just a part of one’s life. To work means to live, and to live must involves work.
First, when one works, he also lives. There is not a period of time when one is only working but not living. Therefore when one works hard and feels happy about his achievements, he is also living fruitfully. There is no need to say that he just "lives to work". Second, it is impossible to imagine a life without work. Marx once said that work is the basic need of the human race. Work is not only a breadwinning process, but is also a process of exploring the unknown world, creating beauty, providing help, expressing love, friendship and care. Anyone would hate a life without work, and I think only those who work well enjoy their life best.To conclude, I am firmly convinced’ that work is a part of life. So enjoy your work, for when you make progress and have fun in your work, you are also enjoying your life.

The Impact of Air Pollution
The cartoon vividly reveals the phenomenon of air pollution or the decline of air quality. In the cartoon we can see the air pollution is so serious that the earth can't bear it.
What exactly contribute to this phenomenon? Possible reasons can be listed as follows: firstly, vehicle exhaust gases could be one of the most leading causes. With the improvement of economy and people's living standard, urban inhabitants in mounting numbers own their private cars. More automobiles will inevitably generate more exhaust gases. Additionally, household appliances widely used in cities also release a great amount of carbon dioxide gases, which further intensifies air pollution. Last but not least, many factories around the cities emit large quantities of untreated poisonous gases, which should also be responsible for the decline of air quality.
Definitely, air pollution will exert a detrimental impact on many aspects of people's life. For example, many diseases such as cough, skin problem and lung cancer are caused by it. Perhaps it is high time that we should adopt some measures to solve the problem of air pollution.

Nowadays, more and more college students are addicted to online games. Those games may be funny and exciting, but are very harmful to those addicts.
In my opinion, there are many disadvantages of game , online games take up a lot of players’ time for study. Many of the addicts found themselves forced to drop out of school for poor academic performance. Secondly, addicts tend to isolate themselves from the reality. What’s worse , indulging in the virtual world for a long time, they are more liable to suffer mental problem and physical collapse. Thirdly , players are exposed to too much violent and unhealthy material, which is definitely harmful to their growth.
In short,I cannot see any benefits from online should be the primary concern of college students. Therefore,I do hope they can step away from online games.

英語專業(yè)四級作文 篇三 Why a Sense of Humor Is Important
A sense of humor, God’s greatest gift to mankind, is universally considered the most valuable personality asset. Everyone is born with it, but we still have to cultivate it. A person without humor is just like a spring without flowers. In a sense, your personality lies in your sense of humor.
Humor can enhance physical as well as mental well-being. It helps us bear our burdens, lessen our tension, overcome our frustration, relax our body muscles, and dissolve countless trifles and
irritations. With a crack of joke, all our worries, sadness and tension and tiredness disperse like mist and smoke, and we are full of vim and vigor once again.
Humor helps us live in harmony with others. It is unavoidable to have misunderstanding and tension with others during work and study, but humor is a rubber sword—it allows you to make a point without drawing

Will Electronic Dictionaries Kill Printed Dictionaries?
Many people today prefer to use electronic dictionaries rather than printed ones, because electronic dictionaries are much lighter and smaller and easier to be taken everywhere. Some people worry that printed dictionaries may disappear one day. But I believe that electronic dictionaries will not kill printed ones.
First, printed dictionaries are much cheaper than the electronic ones.
Many students, who use dictionaries most often, can hardly afford an expensive electronic dictionary. Therefore, the printed ones are exactly what they need. Second, scholars prefer printed dictionaries to electronic ones. Holding a thick, heavy dictionary is what a teacher used to do, and I believe that they will like to keep this habit. Third, only the printed dictionaries can be colleted into libraries or be put on our private bookshelves. We may use an electronic dictionary very often, but we will never collect it, since it’s designed to be used, not to be collected.
Of course electronic dictionaries will be more popular in the future, because they are really convenient. But the printed ones are still needed and will not be replaced. The two kinds of dictionaries are just complementary to each other.

With Intelligent Machines to Do the Thinking, Will Our Brains Get Lazy?
Nowadays, many aspects of people’s daily life have undergone considerable changes because of the recent development in artificial intelligence. Obviously, artificial intelligence has already completely renovated people’s lifestyle. On the one hand, the contribution of artificial intelligence to the society is prominent and people’s dependence on it is an irreversible trend. People enjoy the benefits and convenience brought by intelligent machines. On the other hand, people are still concerned about its negative impact, for example, whether our brains will regress with intelligent machines to do the thinking.
In my opinion, artificial intelligence will enable our brains to get more creative. Admittedly, a lot of work has been done by intelligent machines. It seems that the function of people has been weakened and people’s brains have been replaced. As a matter of fact, thanks to intelligent machines, people can expand their creative energy and add new varieties. Simply speaking, when people are free from tedious, repetitive, sometimes even dangerous work, work efficiency will undoubtedly be improved. As a result, people can spare more time to do what they want and pursue what they dream of, which is the premise of creativity. Moreover, creativity stems primarily from knowledge and thinking. Once people have the opportunity to do more thinking and learning, their intelligence would be enhanced rather than weakened.
Although artificial intelligence is the exhibition of people’s high degree of creative power, it should be noted that it is like a double-edged sword. The sensible choice is to embrace its advantages and cope with the problems it has aroused. This is what an advanced and rational society should be like.

專四作文10
Honesty means speaking the 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,money,intelligence,honesty,reputation and talent,honesty is the only thing that can be erased away. They don't understand or pretend not to understand that honesty is the biggest fortune human beings own,and that it is the prerequisite for doing everything well.
I think these people are to 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.
專四作文11
在平時，總有很多同學寫信來詢問同樣的一個問題：“我怎樣才能夠在短時間內(nèi)提高我的專四寫作水平？”答案其實是否定的。首先我們必須明確：冰凍三尺，非一日之寒；英語學習是一個長期積累的過程，短期的突擊無異于舍本逐末、杯水車薪。然而，這并不意味著我們不能夠通過掌握考試規(guī)律來調(diào)整我們的臨考狀態(tài)、提高我們的應考能力。以下，我想就如何利用應試規(guī)律、最大限度地發(fā)揮同學們的寫作水平談7點個人的看法。
1、心理
古人云，不戰(zhàn)而屈人之兵，很大程度上取決于心理因素。隨著考試改革的深入，會有更多，更新，更難的題目，包括作文題目出現(xiàn)，這樣就要求我們有處驚不變的能力。即使是出現(xiàn)某種沒有預料到的題型，考生也應該及時調(diào)整心態(tài)、從容不迫地應答。事實上，歷史經(jīng)驗證明：題目要求越是高，難度越是大，考生的發(fā)揮余地也就越大。挑戰(zhàn)和機遇是成正相關的。
2、評分
知己知彼，百戰(zhàn)不怠。熟悉老師的評分習慣，對于考生正常、甚至是超常發(fā)揮自身水平也十分有益。正常情況下，閱卷老師要領會貫徹考試規(guī)定的評分原則，依照文章的結構和語言水平進行評分。然而，除此以外，有“兩個基本點”我們也需要給予足夠的重視――閃光點和語法點。在一篇出類拔萃的范文中，我們往往可以看到像提問法、諺語總結法、從句、并列句、理由段公式、理由詞匯、路線句型、插入語、名詞化、和被動語態(tài)等等閃光點；而在一篇低分例文中，基本的語言錯誤則多得數(shù)不勝數(shù)。
3、審題
磨刀不誤砍柴工。在落筆前花兩三分鐘時間進行構思，既有利于理清行文思路、也避免了差之毫厘、失之千里的遺憾。尤其是在應對圖表類作文時，我們更是要看清圖表，牢牢把握各個數(shù)據(jù)的變化和相互關系，才能夠下筆。否則張冠李戴，即使文章本身再不同凡響、語驚四座，也只會竹籃打水、甚至起到適得其反的效果。
4、卷面
對于像作文這樣的主觀題而言，考生與閱卷老師從來就猶如搏弈，無形中彼此互動、相互影響。一個考生可以做的，首先是通過卷面給閱卷老師下意識地傳達個人信息。用筆的顏色（深藍色使人心情放松愉快）、粗細（粗線條給人以安全感），整齊劃一的格式（段首或一律頂格或一律空兩格），明了的段落感（每段空一行），清晰的字數(shù)感（一行以十字為宜），工整的字跡都會給任何閱讀者留下深刻的正面印象，從而使考生先發(fā)制人、取得先機。
5、結構
有始有終、首尾照應，是任何一篇好文章的基本標準之一，也是兩大評分原則之一。如果說廣大考生已經(jīng)給第一段以足夠重視的話，那么是不是大多數(shù)考生都意識到了理由段的條理和最后一段的呼應在全文中所具有的不可忽視的地位了呢？其實，要寫好理由段，我們只需要注意表示啟承轉合的銜接詞即可。而要寫好結尾，最好的方法莫過于溫故而知新，回顧第一段的大致內(nèi)容了。
6、表達
言之無文，行而不遠。語言作為評分原則中的基本要素之一，在專四作文評分的整個過程中具有決定性作用。有評分老師甚至斷言：“It is not what you say，it is the way that you say it.”（重要的`并不在于考生寫了些什么，而在于考生是怎么表達的。）雖然這種說法本身似乎有失偏頗，可是參加過國際標準化英語考試的同學應該也聽說過那么一句話，叫做：“Give the monkey exactly what he wants.”（給閱卷老師最想要的。），不是嗎？譬如同樣是描述數(shù)據(jù)，一些同學拘泥于圖表本身，動輒按部就班地引用圖表上現(xiàn)成的數(shù)字和年代，其實這都是圖表作文的忌諱。聰明的同學引而不用，他們常喜歡用倍數(shù)、分數(shù)、小數(shù)、百分比、或者一些動詞（double / triple / quadruple）來表現(xiàn)極端數(shù)據(jù)，動態(tài)數(shù)據(jù)以及他們的相異之處。
7、檢查
行百里者半九十。一篇成功的作文少不了反復推敲、一再修改。然而，由于考試時間和條件等諸多因素的限制，考生絕對需要慎重對待作文的檢查和修改。這里，我不得不提考生檢查作文時的三大“通病”，即，數(shù)字數(shù)、孤芳自賞、和做結構與內(nèi)容上的修改。我們必須明確：考試作文的潤色和修改只需要達到三個目的即可：1.拼寫正確，看文章中是否有漢字、多余符號、糊亂涂改、劃線、和錯別字；2.搭配正確；和3.語法正確，特別是人稱、時態(tài)、和單復數(shù)的三“一致”。
專四作文12
My Advice to the Undergraduates
Because of the severe competition in the job market, it's quite difficult to get a decent job for a college graduate. Many college students complain that graduation means the coming of unemployment. To avoid this dilemma, I have some advice to the undergraduates.
To avoid unemployment after graduation, the undergraduates have to prepare themselves for the job-hunting long before their graduation. First, study as hard as you can. Surely an applicant with more high marks in his resume will be more likely to get a job. And a hard-working student can acquire more knowledge and pass interviews easily. Second, get a part-time job which is related to the job you want to get in the future. Many college students like to find a part-time job, but most of them do this only for pocket money. Can this part-time job be written into your resume as a related job experience? Can this part-time job bring you new friends who are doing the very kind of job you want to do after graduation? Think it over and make full use of your part-time job.
If the undergraduates prepare themselves well for the job-hunting, they will have more chances to find a good job after graduation.
專四作文13
Students with "hot" degrees like computer science or finance are more likely to get a job than students with a "cold" degree like geography. Should universities give priority to practical or traditional courses?
Write on ANSWER SHEET THREE a composition of about 200 words on the following topic:
Should Universities Give Priority to Practical Courses for Students?
You are to write in three parts:
In the first part, state specifically what your idea is.
In the second part, provide one or two reasons to support your idea OR describe your idea.
In the last part, bring what you have written to a natural conclusion or a summary.
Marks will be awarded for content, organization, grammar and appropriateness. Failure to follow the instructions may result in a loss of marks.
專四作文14
I am not supportive of the idea that either takes priority. It is necessary and absolutely possible that economic development and environmental protection co-exist, in the sense that both of them are indispensable factors for the prosperity of society.
Economic development is seemingly more important, due to the fact that it creates enormous job opportunities, improves living conditions and increases government revenues. Yet, the above goals can only really be reached on condition that the environment is well protected. And, interesting, it is the economic development per se that provides the money and personnel resources required for the protection of the environment. A well-preserved environment is the groundwork for the economy and in a way promotes economic growth. A fast-development and well-functioning economy calls for a good environment, which offers essential resources, e.g. wood, coal, water, and so on. Once the environment deteriorates, the production process is likely to be disturbed or even halted. What is worse, natural disaster that comes with the worsening environmental conditions might even paralyze the whole economy and pose a severe threat to human life. The pursuit of short-term economic profit is the destruction of our home and that of our posterity.
So economic development and environmental protection are equally important. In this case, we are actually working on an environment-friendly economy.

Ways to Get Over Information Explosion As a popular saying goes, "A wealth of information creates a poverty of attention.
隨著信息爆炸的流行，人們說：“信息的豐富性造成了人們的關注，如今我們正處于信息爆炸的時代。
" Nowadays we are in an era of information explosion.
越來越多的人抱怨他們在信息時代迷失了。
More and more people complain that they are lost in the information age.
誠然，沒有人能否認這個事實：新信息時代給我們帶來了如此多的便利，我們可以得到足夠的信息，只是用一個簡單的點擊坐在電腦前。
Admittedly, no one can deny the fact that the new information age has brought us so much convenience that we are allowed to get plenty of information just with a simple click sitting in front of the computers.
盡管如此，我們也很困惑、不安、心煩意亂、心煩意亂的是一個令人難以置信的大量的信息。
Nevertheless we are also confused, annoyed, distracted and upset by an incredibly large quantity of information.
例如，在網(wǎng)上搜索的東西，人們很容易被誤導的不相關的信息，忘記他們的原始計劃。
For example, when searching for something online, people are easily misguided by irrelevant information and forget their original plan.
此外，一些信息往往是無用的。
Besides, some information often turns out to be useless.
因此，它可能是耗時和麻煩的搜索信息在線。
Therefore, it may be time-consuming and troublesome to search information online.
那么我們可以做什么來避免被不相干的信息分散?
Then what can we do to avoid being distracted by irrelevant information?
以下是一些有用的建議：首先，在你的搜索前，列出你想要的。
Here are some useful tips: Firstly, make a list of what you really want before your searching.
你可以通過這種方式避免一些有吸引力的，但不相關的信息。
You can avoid some appealing, yet irrelevant information by this way.
然后，找到一些可靠的和專業(yè)的來源或網(wǎng)站，然后保存和分類。
Then, find some credible and professional sources or websites and then save and categorize them.
在這種情況下，你可以很容易地離開一些廣告和無用的信息。
In this case, you can easily leave some advertisements and useless information behind.

汽車和道路使交通運輸快捷方便，工廠生產(chǎn)的產(chǎn)品使我們的生活更舒適，在城市的公共服務，如水處理，電力，和廢物處理，使我們的生活更方便。
All of these advances, however, come with a significant environmental cost.
所有這些進展，但是，有一個顯著的環(huán)境成本。
Human activity does significant damage to the Earth.
人類活動對地球造成重大損害。
One of the main effects of human activity on an area is water pollution.
人類活動對一個地區(qū)的主要影響之一是水污染。
Dumping waste materials from human activity into rivers and streams is popular because the waste seems to disappear downstream.
從人類活動到河流和小溪的傾倒廢物的材料是流行的，因為廢物似乎消失了下游。
The main sources of water pollution are factory waste, oil and gas runoff from highways, and untreated human waste.
水污染的主要來源是工廠的廢水、公路的石油和天然氣，以及未經(jīng)處理的人類廢物。
When this waste dumped into rivers, the water downstream becomes undrinkable and unusable for agriculture, and also kills plant and animal life in the rivers.
當這些廢物排入河流，下游的水就不能喝，不能用于農(nóng)業(yè)，并殺死植物和動物生命的河流。
Clean air and water is a prerequisite not only for human life, but also for all life on the planet.
清潔空氣和水是人類生活的前提，也是地球上所有生命的先決條件。
But air is now being polluted by modern transportation, notably gas-powered automobiles, as well as electrical generators that burn fossil fuels and pour polluting chemical waste into the air.
但是，現(xiàn)在的空氣污染正受到現(xiàn)代交通運輸業(yè)的污染，尤其是天然氣汽車，以及燃燒礦物燃料的.發(fā)電機，把污染的化學廢物傾倒在空氣中。
This makes the air much less healthy to breathe.
這使得空氣更不健康的呼吸。
The air-borne pollution also falls back to the earth in the form of acid rain, which destroys plant life and human buildings.
空氣污染的污染也以酸雨的形式返回到地球，這破壞了植物的生命和人類的建筑。
Another serious long-term effect of air pollution is global warming.
空氣污染的另一個嚴重的長期影響是全球變暖。
For the past several decades scientists have noted a disturbing rise in the average temperature of the earth that caused by the rise of greenhouse gases, air pollutants created by burning fossil fuels, in the atmosphere.
在過去的幾十年里，科學家們已經(jīng)注意到地球的平均溫度上升了一個令人不安的上升，溫室氣體的增加，燃燒礦物燃料產(chǎn)生的空氣污染物，在大氣中。
Scientists believe that if humans continue to increase the amount of greenhouse gases in the atmosphere, the temperature of the earth will continue to rise.
科學家認為，如果人類繼續(xù)增加大氣中溫室氣體的量，地球的溫度將繼續(xù)上升。
Eventually, this could melt the polar ice caps and cause devastating costal flooding all over the world.
最終，這會融化極地冰蓋和世界各地的沿海洪災造成毀滅性的。
Major cities like Hong Kong, Shanghai, and Dalian might be totally destroyed.
像港、上海、大連這樣的大城市，可能會被徹底摧毀。
Therefore, I believe human activity has caused serious problems while it has improved the world in which we live.

It is time to realize this hazard and take action to prevent further disaster while making progress.
是時候認識到這一危險，并采取行動，以防止進一步的災難，同時取得進展。
