The weather of these days is really bad. It's foggy and there is haze in the air. So, we can't see the things very far. Every morning, when I pull back the curtain, I only can see the building dozens miles away. When I go to school, I must be very careful when I go across the street. Besides, the air is dirty because of the haze. I even feel hard to breathe. My mother tells me to wear a respirator. I do as she tells. Because of the bad weather, car accidents happen more frequently. I hope drivers can drive more carefully and keep safe....

四年級下冊習作4以霧霾為主題寫一篇作文
霧霾與我們生活這個冬天霧霾天氣備受大家的關注，霧霾危害較大，有好幾個城市已經中了它的招，所以我們應該增強環境管理的力度，不再讓霧霾天氣橫行。
霧霾的成因想必有不少人知道，霧霾嗎，當然是由霧和霾組成的，霧的主要成因是大量懸浮在地面空氣中的微小水滴或冰晶組成的氣溶膠系統，是近地面層空氣中水凝結的產物。
霧主要會使能見度降低，會造成交通隱患，但對人的危害不大。
霾是由空氣中的灰塵、硫酸、硝酸等有害物質組成，它會使大氣渾濁，視野模糊並導致能見度降低，並且會對人體造成較大的傷害。
這樣一來霧和霾兩個本不相乾的兄弟聚到了一起，對大氣造成空前的破壞，有些城市的空氣質量已經到了中度污染的地步，更有些城市已經達到了重度污染，非常可怕。
霧霾的危害相當大，它會對公路、鐵路、航空、供電系統、農作物生長造成影響。
還易導致傳染病擴散和多種疾病發生。
危害人的健康。
並且會導致空氣中污染物不易擴散，增強有害物質的毒性，嚴重的，還可能會導致毒霧發生。
並且會對人造成巨大傷害，特別是對呼吸系統影響很大。
有報道稱，這個冬天呼吸系統發病的人比上個冬天增加了%30---%40。
這是一個多麼驚人的數字，值得我們深思。
所以防治霧霾天氣刻不容緩。
我們的防範措施應該到位，在霧霾天氣時，我們應該停止晨練和戶外運動。
只是這樣還不夠，我認為造成這種惡劣天氣的主要原因是汽車尾氣的排放和工業生產廢氣的排放，所以國家應該盡快下達政策來管理和控制有害氣體的排放，多植樹種草，凈化我們的環境。
我想，如果大家都動員起來，霧霾天氣就應該灰溜溜的逃跑了吧。
總之，我希望大家可以行動起來，多種草種花，多保護環境，為我們的子孫後代營造一個綠色，天然的環境。
關於霧霾的作文有哪些
清晨去上學，天還沒亮，大霧朦朧.走在馬路上，只能遠遠的看見那模糊的車燈.一輛自行車從我身邊飛速駛過，我嚇了一跳.好危險，如果不是幸運，估計我現在已經被撞得躺在了地上.事後，我真有些後怕：如果在這樣下去，那我們以後周圍的環境全都被霧霾包圍著，直到伸手不見五指，全是白茫茫的一片，真是可怕，要知道，霧霾中含有大量大氣顆粒物.其中有害人類健康的主要是直徑小於10微米的氣溶膠粒子，如礦物顆粒物、硫酸鹽、硝酸鹽等，它能直接進入並黏附在人體上下呼吸道和肺葉中，引起鼻炎、支氣管炎等病症，長期處於這種環境會引發肺癌.霧霾除了對人身體健康有害以外，還容易造成交通事故.每天的上班高峰時間，馬路上的車川流不息，人們都趕著去上班，特別是那些司機朋友，霧霾擋住了他們的視線，十分容易造成交通事故.霧霾造成的交通事故也不少了，我希望從現在開始，不再出現不必要的事情.那為了保護我們的身體健康，和杜絕這種交通事故的再現，我們應該怎麼做呢？首先我們要盡量減少外出.必須外出時一定要戴口罩，防止空氣中的小顆粒進入肺里. 在家裡要關閉門窗.由於霧霾天氣時，空氣中的污染物難以消散，在大霧的天氣應緊閉門窗，避免室外霧氣進入室內污染室內空氣，引發急性呼吸道和心血管疾病的發生. 我們還注意飲食.多飲水.要注意飲食清淡，可以多吃些豆腐、牛奶等食品，必要時要補充維生素D. 外出時開車走路要倍加小心.霧霾天氣下，能見度較低，視線差，駕車、騎車和步行的人們都應多加註意，特別是通過交叉路口和無人看管的鐵道口時，要減速慢行，遵守交通規則，盡量避免發生交通事故.最最重要的是愛護植被，每片樹葉都是一個過濾器，在光合作用中，葉面上的氣孔敞開著，空氣中的有毒物質隨著空氣進入葉組織，儲存在植物體內；而光合作用釋放出來的氣體則是純凈清新而無毒的.朋友們，霧霾對我們的危害是多麼大啊！希望大家能互相傳播，保護環境，從我做起.人人都愛護環境，那麼世界將告別霧霾，世界將會是一個美好的明天！
關於霧霾的作文400字
又是一個灰濛蒙的早晨，我倚在窗前不敢開窗，鼻子貼著玻璃使勁往外瞧，外面的一切籠罩在漫天的塵霧中，依稀間有幾輛汽車晃著昏黃的大燈在慢慢爬行。
一切都顯得毫無生氣。
連太陽也懶得露臉，黎明、晨曦、朝陽都遠離了這個早晨。
又是一個霧霾日，不要外出，減少室外活動，這該死的霧霾似乎想把我們禁錮在有限的空間，感冒、咳嗽、發熱，這可惡的霧霾彷彿想把人間變成細菌的世界，以前我們總把惡劣的天氣說成是電閃雷鳴，風雨交加，然而雷電有它瞬間的震撼和 *** ，風雨又給人無限的憧憬和幻想，唯有這霧霾十惡不赦。
我多麼希望刮一陣大風吹散這滿天的霧霾，下一場大雨把地球沖刷得乾乾凈凈。
憋了一整天，我想到外面活動一下，外婆逼著我戴上口罩，說實在的，我討厭這口罩，它阻礙了人與人的交流，掩蓋了人的本來面目。
像疑犯，像蒙面人，實在不好受，小區的草坪上，鄰居阿姨帶著它的愛犬在遛狗，阿姨戴著厚厚的淺藍色的口罩，那狗居然也戴著大大的黑口罩，看來這霧霾也危及到了動物，忽然我聽到高大的香樟樹上有幾只小鳥在嘰嘰喳喳地高聲鳴叫，霧霾里它們是那麼地勇敢。
突然，我聽懂了它們的叫聲，它們在竭力喊著環保口號：減少污染，保護環境，保護我們共同的家園——地球。
關於霧霾的作文怎麼寫？
最近一段時間，天氣總是霧蒙蒙的，早晨起來，周圍原本美麗的景物變得十分模糊，新聞上也頻頻報道霧霾天氣的不斷出現而帶來的嚴重後果，霧霾天氣已經嚴重的影響到了空氣質量，影響到人們的正常生活。
近年來，霧霾天氣不但嚴重的影響了空氣的質量，更是容易引發哮喘等疾病的主要來源。
霧霾天氣的空氣中，包含了一些塵土形的微小顆粒，這些微小的顆粒是我們用肉眼無法看見的。
這些微小的顆粒足以使人們得上肺病。
它們，可稱得上是無形殺手。
那麼，霧霾天氣究竟是由什麼而引起的呢？其實，霧霾天氣就是由汽車尾、炒菜的油煙、還有吸煙吐出的煙、煙花的煙形成的，從而引發霧霾天氣的出現。
不要說霧霾天氣是殺手，更不要說霧霾天氣很可怕，其實，真正的兇手還是我們人類，是人類不懂得保護環境，是人類要破壞自己的家園，所以才引起霧霾天氣，這些都是人類自食其果。
當然啦，現在的局勢還是無法挽回，我們還是可以阻止霧霾天氣的。
我們可以把汽車改成騎自行車；可以不吃炒菜，吃燉菜；可以戒煙或可以把吸完煙的煙頭仍到垃圾桶里；可以少放煙花爆竹；還可以多種植花草樹木，來凈化環境。
只有我們選擇低碳生活，才能阻止霧霾天氣的發生。
有時候，我真希望，汽車里噴出來的不是難聞的尾氣，而是淡淡的芳香，煙囪里吐出來的不是濃濃的黑煙，而是晶瑩的露珠，。
我真希望，我們的家園能變得樹更綠、花更紅、小鳥的歌聲更動聽、更悠揚。
我相信，只有大家行動起來，從自身做起，我們的夢想一定會成為現實，讓我們大家一起努力，保護環境，保衛我們的家園，讓霧霾天氣不再危害人間，使我們的家園更美好。

霧霾 作文 材料作文300字
望一眼窗外，突然發現看不到藍天、白雲，天地間一片灰色的景象，連對面的樓房也只有朦朧的輪廓。
這樣的天氣越來越頻繁，霧霾正無聲無息地籠罩著我們的城市。
霧霾是霧中懸浮著大量的煙、灰塵等微粒而形成的混濁現象。
據環保部遙感衛星監測：1月29日中國范圍內有130萬平方公里的地區被霧霾籠罩，空氣質量嚴重污染。
那霧霾天氣是怎樣來的呢？很多家庭都擁有小汽車，我們的出行更便捷了，但汽車的尾氣排放污染空氣；電廠、煉油廠、化工廠在我們的城市裡「大顯身手」，但夜以繼日地不斷排放出煤煙和灰塵；絢麗的煙花爆竹讓人目不暇接，但空氣中煙霧騰騰，變得非常混濁，空氣質量急劇下降，PM2.5、PM10指數直線上升，這些都是造成霧霾的主要原因，它們在帶給我們快捷方便、賞心悅目的同時，也悄悄給我們帶來了意想不到的後果。
霧霾的天氣，我們呼吸的是混濁的氣體。
空氣中的霾會引起肺炎、咽喉炎、氣管炎、心臟衰落等疾病。
1952年，英國倫敦的那場大霧似無形的殺手，在短短五天內就奪取了4000人的生命，在之後兩個月內有奪去了8000人的生命，可見大霧的威力，也該給我們敲響了警鍾。
我們要的是清新的空氣，要的是健康的體魄。
請不要以犧牲健康為代價，而換來所謂的美好生活。
少開車，綠色出行，多種樹，保護森林。
治霾，從我做起。

A Letter of Advice
Dear Freshmen,
I, the undersigned, am a senior in the Computer Science Department of Peking University. I would like to say a few words to you, which I hope would be helpful to you.
To begin with, the change of ideas is of most importance for freshmen to adapt themselves to campus life. During the middle school days, we usually depend upon our teachers at school and parents at home. However, the life and study on university campus features independence, which is essential to our psychological development. In my view, we had better always bear in mind the idea of independence.
What』s more, English learning is a must. On one hand, without CET 4 certificate, we can not get our degree when we graate from university. On the other hand, when we hunt for job, English level is a deciding factor. Therefore, I do hope that all of you will have a good understanding of the necessity of learning English well.
Good Luck to you!
Sincerely Yours
Li Ming

1. 「永不言棄」一直被認為是一種積極的生活態度，是個人成功的關鍵因素
2. 但是，也有人認為適當的放棄才是明智的選擇
3. 你對此的看法及理由
【範文】
Do We Need 「Never give up」?
It is widely accepted that 「Never give up」, a strong and positive life attitude, is the key for indivial success on the grounds that permanent persistence may boost our confidence, strengthen our will, and provide us a second chance for success when we are in hardship. However, others argue that sensible abandonment is more precious than blind persistence because the wise one should choose the most suitable area for himself/herself.
In my opinion, we need to learn to give up timely. The most immediate reason is that we should adjust our aim carefully in order to go ahead continuously. Sometimes, to give up those unrealistic targets is essential for success. Besides, the attitude 「Never give up」 exhausts us both mentally and physically. Only through learning to give up can we lead a pleasant and relaxing life. Finally, the temporary comprise means a new start, a beginning bringing new hopes, expectations and opportunities for us.
Passive as giving up sounds alike, it represents a more mature and realistic mentality. If those opposing this attitude can take into consideration of its benefits, then this may seem acceptable in our lives.

毫無疑問，一個和諧的校園是極為重要的。關於建設和諧校園的討論，下面我整理的四級英語作文中就有，歡迎大家閱讀!
建設和諧校園
There is n6 that that a harmonious campus is of vital importance.Just like a credible, colorful and appealing textbook, it nurtures students' mentalities, beautifies their minds, enlightens their wisdom andaccelerates their overall development.
When it comes to a harmonious campus, we do not merely refer to a clean environment on campus but also a healthy interpersonalrelationship: teachers and students get along well with each other, andstudents respect and care for each other. More importantly, it has beenuniversally acknowledged that a sustainable campus arouses the creativityof teachers and students and at the same time reinforces campusregulations and maintains campus order.
Cosidering the importance of a harmonious campus, joint efforts ofhtstitutmd students mtt belaken. First of all. it is high time that collegesand universities introced advanced campusculture which encourages avariety of creative extra-curricular activities. At students should behave themselves, learn to be tolerant and respect each other.
參考翻譯：
毫無疑問，一個和諧的校園是極為重要的。就像一本可信的、豐富多彩的而又有吸引力的教科書，它培育學生的心態，美化他們的心靈，啟迪他們的智慧，加速他們的全面發展。
當提及和諧校園時，我們不僅是指干凈的校園環境，還包括健康的人際關系，老師和同學相處融洽，學生之間相互尊重和照顧。更重要的是，人們公認，一個可持續發展的校園可以調動教師和學生的創造力，並強化校園規章制度，維護校園秩序。
鑒於和諧校園的重要性，學校和學生必須共同採取措施。首先，高校引進先進的校園文化、鼓勵多種創意的課外活動正逢其時。與此同時，學生應該規范自己的行為，學會寬容和相互尊重。
佔座
On campus, it is a common phenomenon for students to occupy seats. In the library, classrooms, and even the canteen, you can find books and pens claiming the temporary usage of the tables and seats. This issue has aroused public concern. Some people hold that it is a wrong and impolite behavior which should be fought against, while others argue that students should not take the blame since colleges fail to provide sufficient study facilities. There is probably some truth in both sides. As to me, I'm in favor of the former argument. For one thing, occupying seats inevitably worsens the problem of resource shortage. The seats will remain empty until the occupiers come. For another, taking up seats does harm to the harmonious campus atmosphere when friendship and modesty give way to improper competition. Therefore, I strongly oppose this kind of act.
在大學，佔位是個很常見的現象。在圖書館，教室，甚至是食堂你都能發現書和筆在占據著座位代表著臨時的座位使用權。這個問題引起了廣泛的關注。一些人認為佔座是錯誤和不禮貌的行為應該廢除而另外一些人認為自從大學不能提供足夠的設備給學生後這學生就不應該被指責。這在某種程度上來說是對的。而在我看來，我更贊同前者的觀點。首先，佔位讓這種資源短缺的現象更加的糟糕。這個座位將會保持無人狀態知道那個佔位人來了為止。其次，當友誼和謙遜被錯誤的競爭取代的時候，佔位不利於校園的和諧氣氛。所以，我強烈反對這種行為。
我的夢想
我的夢想長大是當一名畫家，我之所以想當一名畫家，是因為我特別喜歡畫畫。
My dream is to be a painter, I wanted to be a painter, because I like to paint.
每當我在外面看見美麗的大自然風景和動人的場面，我的心情就特別激動，我很想把這些都畫下來，這樣將來這些美好的畫面好永久的.存在我的心裡。
When I see a beautiful natural scenery on the outside and a moving scene, my mood is very excited, I really want to put these are drawn down, so that these beautiful picture good forever in my heart.
每當我知道哪裡有畫展，我都要去看，當看到作者畫的祖國的大好河山，還有爭齊斗艷的花兒和栩栩如生的動物……這些都好像讓我走進了一個美妙無比的世界，我很佩服這些畫家們，把人間的一切美好的事物描繪的那麼真實，能讓更多的人來享受這大自然的美。
I know where the exhibition, I went to see the beautiful mountains and rivers, the painting of the motherland, as well as for Qi Yan flowers and the animal...... All these seem to let me into a wonderful world, I admire these artists, all the good things the world portrayed so real, to allow more people to enjoy the beauty of nature.
每次，我看完畫展回來，都會高興很長時間。有時學校有畫畫展覽，我都要參加，雖然畫的不是太好，但我會用心去畫的。
Every time I read back, exhibition, will be happy for a long time. Sometimes school painting exhibition, I have to attend, although the picture is not very good, but I will work hard to draw.
我知道要想成為一名畫家，要付出很多。所以從現在起，我要下定決心，努力學習，這樣在畫上才能有進步。我想：只要肯下功夫，就一定能把畫畫好，我的夢想就一定會實現。
I know that if you want to become a painter, to pay a lot. So from now on, I was determined to study hard, so that we can draw on the progress. I think that as long as willing to work hard, we will be able to draw well, my dream will come ture.
;Ⅳ 求空氣污染的英語四級作文 air pollution 120個字左右
1.
Air pollution is one of the major problems of the modern world. A great deal of energy is needed to run the factories of modern instrial nations. Automobile, trains, planes and busses need energy, too. Nearly all of this energy is proced by burning fuels. The burning proces wastes, some of which remain in the air, causing air pollution.
Scientists are finding ways to stop air pollution especially in big instrial areas and densely-populated cities. They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluted material. Also, engineers try to design and locate new power plants to do minimum damage to the environment.
However, it may be that we still have a long way to go before we have a "clean" world. Nearly all of the countries are trying hard to prevent and control air pollution. There indeed seems to be no end to tasks that environmentalists will be required to do. People will continually find new ways to control pollution.
2.
The impact of air pollution on climate
Air pollution is now discussing how they affect climate. The most serious air pollution is generated by burning: the burning of sulfur in coal and oil, will proce sparse oxides; air to participate in high-temperature reaction, will proce nitrogen oxides; will proce incomplete combustion of hydrocarbons and carbon monoxide; while combustion of pyrolysis gasoline, but also release lead; ... .... However, even the cleanest fuel combustion will proce carbon dioxide. Of course, the animal's breathing process, the same release carbon dioxide, and that of carbon dioxide into the atmosphere, about 80% came from breathing, only 20% from fuel combustion. However, the burning destroyed the natural balance of carbon dioxide, so that the concentration of atmospheric carbon dioxide increased year by year, which may cause the "greenhouse effect", so that the earth's rising temperatures.
Turbidity current growth rate of the Earth, or even greater than the concentration of combustion caused by cO2 growth rate, therefore, atmospheric turbidity will influence the Earth's climate can not be ignored. The increase in turbidity over the world there are many reasons, such as fuel consumption increase, fuel increase in agricultural machinery, mechanized farming, and so an increase in Young earth.
In addition to the greenhouse effect and atmospheric turbidity may affect the Earth's climate, other factors such as sunspot activity, etc., to some extent also affect the Earth's climate. Sunspot activity since 1900 are constantly increasing. As the sunspot can increase the amount of solar radiation and thus cause rising temperatures.
The air pollution on the Earth's climate, they are not scientifically conclusive evidence on the. Most of was a bold extrapolation.

引導語：學習別人的長處，來完善自己短處，這樣才可以不斷的進步。那麼下面就和我一起來欣賞一下英語四級滿分作文吧，希望可以幫助到大家。
滿分範文一
作文題目：
Intelligence-Nature or Nurture
1) 有人認為智力是天生的;
2) 也有人認為智力是環境決定的;
3) 如何更好地發展智力。
參考範文：
Are some people born clever, and others born stupid Or is intelligence developed by our environment or experience Strangely enough, the answer to both questions is yes。
On the one hand, if we take two people at random from the crowd, it is very likely that their degrees of intelligence will be completely different. However, if we take two identical twins, chances are that they will be as intelligent as each other. Therefore, a conclusion can be drawn that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence。
On the other hand, though, if we put two identical twins in different environments, for example, we might send one to university and the other to a factory where the work is boring, we would find differences in their intelligence several years later, which indicates that environment does play a crucial role in our intelligence。
Just as every coin has two sides, our intelligence is partly born and partly developed. The sure way to develop our intelligence is intelligent parents as well as a good environment.

2. 也有人堅持在國內也能實現自己的理想;
3. 我的'看法。
參考範文：
With the deepening of reform and opening-up of our country, many people dream of going abroad for further study. They insist that there are more modern research facilities, world famous professors and excellent environment in some foreign colleges and universities, which lay a perfect foundation for their future development. However, there are still many people who favor studying at home. They argue that, for one thing, studying abroad is too expensive and therefore doesn't pay off. For another, there are no language and cultural barriers if they study in our country. Just as the old saying goes, "Every advantage has its disadvantage," so I believe both opinions are acceptable in some sense. If students have the chances and financial resources, they should seize the opportunity to go abroad and broaden their eyes. On the other hand, if conditions don't permit, they can pursue their studies at top universities in our country. What counts is not the place where they study, but what they can learn.

作文題目：
Should CET-4(6) Be Abandoned
1. 有人認為應該廢除大學英語四(六)級考試;
2. 其他人認為應該保留四(六)級考試;
3. 我的看法。
參考範文：
There has been a heated discussion about whether to keep the College English Test Band 4(6) in the universities. Some people argue that the test has become an obstacle to the teaching of English on campuses, while others maintain that the advantages of the test outweigh its disadvantages. As far as the first group of people are concerned, they give the following arguments. For one thing, many students spend most of their time preparing for the test, therefore their focus is not on learning English better but on getting a high mark. For another, many teachers don't concentrate on how to improve the students' abilities. They only care how many of their students can pass the test. However, there are many people who believe the test should stay. To begin with, the test is the most effective way to measure how well the students have learned English. What's more, we can come up with some ways to lessen the negative effect. As far as I am concerned, each side is right in a certain way. We have to keep the test so students will have better motivation to learn English. However, we can't attach too much importance to the scores of the test.

Private cars have become an important aspect of people's life in many parts of our country, especially in large cities such as Beijing, Shanghai and Guangzhou. While they bring much convenience to people, they are also widely criticized. There are some arguments for owning private cars. In the first place, cars allow people to move around freely, which greatly improves our living standard. We can easily drive cars for sightseeing on weekends. In the second place, cars are a comfortable way to travel, especially in bad weather. Last but not least, the car instry can boost economy by creating many job opportunities in proction of steel, rubber, glass and so on. However, there are also many good arguments against cars. First of all, they pollute the environment by emitting harmful gases and giving out loud noises. In addition, cars cause a large number of traffic accidents, which bring great misery to the victims' families. As far as I am concerned, we should limit the number of private cars by providing better mass transportation and better service for the people. Everyone should sacrifice his or her own interest for the common good of the society.
