① 關於大學生需不需要軍訓的英語四級作文

《關於大學生需不需要軍訓的討論》作文:
現在,我想談論關於「大學生需不需要軍訓」的話題。
大學生需不需要進行軍訓?不同的人可能存在不同的觀點。有的人認為,大學生需要進行軍訓很有必要,以培訓學生的國防教育、吃苦精神、團結精神;另外的人則認為,大學生沒有必要進行軍訓,搞好大學的學習及社會實踐活動就行了。
我個人認為,大學生需要軍訓。這很必要,且意義重大。

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....

在北京生活的人們很不好受。

在大街上人們開車速度都很慢,因為沒法看清路面。

很多人還得了霧霾引起的疾病。

造成北京霧霾天氣的因素有很多,汽車、工廠的廢氣啊,工地塵土等。

在我看來,應該限制汽車數量,推動人們選擇公共交通工具。

只有這樣我們才能期待更多大晴天。

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。

③ 關於介紹北京八達嶺長城英語作文

關於長城的英語作文(中英對照)如下:

To the northwest and north of Beijing, a huge, serrated wall zigzags it's way to the east and west along the unlating mountains. This is the Great Wall, which is said to be visible from the moon.

Construction of the Great Wall started in the 7th century B.C. The vassal states under the Zhou Dynasty in the northern parts of the country each built their own walls for defence purposes. After the state of Qin unified China in 221 B.C., it joined the walls to hold off the invaders from the Xiongnu tribes in the north and extended them to more than 10,000 li or 5,000 kilometers. This is the origin of the name Of the "10,000-li Great Wall".

長城的建設開始於公元前第七世紀在周朝諸侯國在該國北部地區建立自己的牆壁,用於國防目的。秦國統一中國後,於公元前221年,它加入了牆壁,把侵略者從匈奴部落在北美和擴展到10000多個鋰或5000公里。這是名稱由來的「長城」」。

The Great Wall was renovated from time to time after the Qin Dynasty. A major renovation started with the founding of the Ming Dynasty in 1368, and took 200 years to complete. The wall we see today is almost exactly the result of this effort. With a total length of over 6,000 kilometers, it extends to the jiayu Pass in Gansu Province in the west and to the mouth of the Yalu River in Liaoning Province in the east. What lies north of Beijing is but a small section of it.

長城是裝修後不時秦朝。一項重大革新始於明代開國1368,並花了200年時間完成。今天我們看到的長城幾乎是這一努力的結果。與總長度超過6000公里,它延伸到嘉魚在甘肅省西部和鴨綠江的遼寧省的東。什麼是北北京不過是它的一小部分。
