《关于大学生需不需要军训的讨论》作文：
现在，我想谈论关于“大学生需不需要军训”的话题。
大学生需不需要进行军训？不同的人可能存在不同的观点。有的人认为，大学生需要进行军训很有必要，以培训学生的国防教育、吃苦精神、团结精神；另外的人则认为，大学生没有必要进行军训，搞好大学的学习及社会实践活动就行了。
我个人认为，大学生需要军训。这很必要，且意义重大。

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....

很多人还得了雾霾引起的疾病。
造成北京雾霾天气的因素有很多，汽车、工厂的废气啊，工地尘土等。

四年级下册习作4以雾霾为主题写一篇作文
雾霾与我们生活这个冬天雾霾天气备受大家的关注，雾霾危害较大，有好几个城市已经中了它的招，所以我们应该增强环境管理的力度，不再让雾霾天气横行。
雾霾的成因想必有不少人知道，雾霾吗，当然是由雾和霾组成的，雾的主要成因是大量悬浮在地面空气中的微小水滴或冰晶组成的气溶胶系统，是近地面层空气中水凝结的产物。
雾主要会使能见度降低，会造成交通隐患，但对人的危害不大。
霾是由空气中的灰尘、硫酸、硝酸等有害物质组成，它会使大气浑浊，视野模糊并导致能见度降低，并且会对人体造成较大的伤害。
这样一来雾和霾两个本不相干的兄弟聚到了一起，对大气造成空前的破坏，有些城市的空气质量已经到了中度污染的地步，更有些城市已经达到了重度污染，非常可怕。
雾霾的危害相当大，它会对公路、铁路、航空、供电系统、农作物生长造成影响。
还易导致传染病扩散和多种疾病发生。
危害人的健康。
并且会导致空气中污染物不易扩散，增强有害物质的毒性，严重的，还可能会导致毒雾发生。
并且会对人造成巨大伤害，特别是对呼吸系统影响很大。
有报道称，这个冬天呼吸系统发病的人比上个冬天增加了%30---%40。
这是一个多么惊人的数字，值得我们深思。
所以防治雾霾天气刻不容缓。
我们的防范措施应该到位，在雾霾天气时，我们应该停止晨练和户外运动。
只是这样还不够，我认为造成这种恶劣天气的主要原因是汽车尾气的排放和工业生产废气的排放，所以国家应该尽快下达政策来管理和控制有害气体的排放，多植树种草，净化我们的环境。
我想，如果大家都动员起来，雾霾天气就应该灰溜溜的逃跑了吧。
总之，我希望大家可以行动起来，多种草种花，多保护环境，为我们的子孙后代营造一个绿色，天然的环境。
关于雾霾的作文有哪些
清晨去上学，天还没亮，大雾朦胧.走在马路上，只能远远的看见那模糊的车灯.一辆自行车从我身边飞速驶过，我吓了一跳.好危险，如果不是幸运，估计我现在已经被撞得躺在了地上.事后，我真有些后怕：如果在这样下去，那我们以后周围的环境全都被雾霾包围着，直到伸手不见五指，全是白茫茫的一片，真是可怕，要知道，雾霾中含有大量大气颗粒物.其中有害人类健康的主要是直径小于10微米的气溶胶粒子，如矿物颗粒物、硫酸盐、硝酸盐等，它能直接进入并黏附在人体上下呼吸道和肺叶中，引起鼻炎、支气管炎等病症，长期处于这种环境会引发肺癌.雾霾除了对人身体健康有害以外，还容易造成交通事故.每天的上班高峰时间，马路上的车川流不息，人们都赶着去上班，特别是那些司机朋友，雾霾挡住了他们的视线，十分容易造成交通事故.雾霾造成的交通事故也不少了，我希望从现在开始，不再出现不必要的事情.那为了保护我们的身体健康，和杜绝这种交通事故的再现，我们应该怎么做呢？首先我们要尽量减少外出.必须外出时一定要戴口罩，防止空气中的小颗粒进入肺里. 在家里要关闭门窗.由于雾霾天气时，空气中的污染物难以消散，在大雾的天气应紧闭门窗，避免室外雾气进入室内污染室内空气，引发急性呼吸道和心血管疾病的发生. 我们还注意饮食.多饮水.要注意饮食清淡，可以多吃些豆腐、牛奶等食品，必要时要补充维生素D. 外出时开车走路要倍加小心.雾霾天气下，能见度较低，视线差，驾车、骑车和步行的人们都应多加注意，特别是通过交叉路口和无人看管的铁道口时，要减速慢行，遵守交通规则，尽量避免发生交通事故.最最重要的是爱护植被，每片树叶都是一个过滤器，在光合作用中，叶面上的气孔敞开着，空气中的有毒物质随着空气进入叶组织，储存在植物体内；而光合作用释放出来的气体则是纯净清新而无毒的.朋友们，雾霾对我们的危害是多么大啊！希望大家能互相传播，保护环境，从我做起.人人都爱护环境，那么世界将告别雾霾，世界将会是一个美好的明天！
关于雾霾的作文400字
又是一个灰蒙蒙的早晨，我倚在窗前不敢开窗，鼻子贴着玻璃使劲往外瞧，外面的一切笼罩在漫天的尘雾中，依稀间有几辆汽车晃着昏黄的大灯在慢慢爬行。
一切都显得毫无生气。
连太阳也懒得露脸，黎明、晨曦、朝阳都远离了这个早晨。
又是一个雾霾日，不要外出，减少室外活动，这该死的雾霾似乎想把我们禁锢在有限的空间，感冒、咳嗽、发热，这可恶的雾霾仿佛想把人间变成细菌的世界，以前我们总把恶劣的天气说成是电闪雷鸣，风雨交加，然而雷电有它瞬间的震撼和 *** ，风雨又给人无限的憧憬和幻想，唯有这雾霾十恶不赦。
我多么希望刮一阵大风吹散这满天的雾霾，下一场大雨把地球冲刷得干干净净。
憋了一整天，我想到外面活动一下，外婆逼着我戴上口罩，说实在的，我讨厌这口罩，它阻碍了人与人的交流，掩盖了人的本来面目。
像疑犯，像蒙面人，实在不好受，小区的草坪上，邻居阿姨带着它的爱犬在遛狗，阿姨戴着厚厚的浅蓝色的口罩，那狗居然也戴着大大的黑口罩，看来这雾霾也危及到了动物，忽然我听到高大的香樟树上有几只小鸟在叽叽喳喳地高声鸣叫，雾霾里它们是那么地勇敢。
突然，我听懂了它们的叫声，它们在竭力喊着环保口号：减少污染，保护环境，保护我们共同的家园——地球。
关于雾霾的作文怎么写？
最近一段时间，天气总是雾蒙蒙的，早晨起来，周围原本美丽的景物变得十分模糊，新闻上也频频报道雾霾天气的不断出现而带来的严重后果，雾霾天气已经严重的影响到了空气质量，影响到人们的正常生活。
近年来，雾霾天气不但严重的影响了空气的质量，更是容易引发哮喘等疾病的主要来源。
雾霾天气的空气中，包含了一些尘土形的微小颗粒，这些微小的颗粒是我们用肉眼无法看见的。
这些微小的颗粒足以使人们得上肺病。
它们，可称得上是无形杀手。
那么，雾霾天气究竟是由什么而引起的呢？其实，雾霾天气就是由汽车尾、炒菜的油烟、还有吸烟吐出的烟、烟花的烟形成的，从而引发雾霾天气的出现。
不要说雾霾天气是杀手，更不要说雾霾天气很可怕，其实，真正的凶手还是我们人类，是人类不懂得保护环境，是人类要破坏自己的家园，所以才引起雾霾天气，这些都是人类自食其果。
当然啦，现在的局势还是无法挽回，我们还是可以阻止雾霾天气的。
我们可以把汽车改成骑自行车；可以不吃炒菜，吃炖菜；可以戒烟或可以把吸完烟的烟头仍到垃圾桶里；可以少放烟花爆竹；还可以多种植花草树木，来净化环境。
只有我们选择低碳生活，才能阻止雾霾天气的发生。
有时候，我真希望，汽车里喷出来的不是难闻的尾气，而是淡淡的芳香，烟囱里吐出来的不是浓浓的黑烟，而是晶莹的露珠，。
我真希望，我们的家园能变得树更绿、花更红、小鸟的歌声更动听、更悠扬。
我相信，只有大家行动起来，从自身做起，我们的梦想一定会成为现实，让我们大家一起努力，保护环境，保卫我们的家园，让雾霾天气不再危害人间，使我们的家园更美好。

雾霾 作文 材料作文300字
望一眼窗外，突然发现看不到蓝天、白云，天地间一片灰色的景象，连对面的楼房也只有朦胧的轮廓。
这样的天气越来越频繁，雾霾正无声无息地笼罩着我们的城市。
雾霾是雾中悬浮着大量的烟、灰尘等微粒而形成的混浊现象。
据环保部遥感卫星监测：1月29日中国范围内有130万平方公里的地区被雾霾笼罩，空气质量严重污染。
那雾霾天气是怎样来的呢？很多家庭都拥有小汽车，我们的出行更便捷了，但汽车的尾气排放污染空气；电厂、炼油厂、化工厂在我们的城市里“大显身手”，但夜以继日地不断排放出煤烟和灰尘；绚丽的烟花爆竹让人目不暇接，但空气中烟雾腾腾，变得非常混浊，空气质量急剧下降，PM2.5、PM10指数直线上升，这些都是造成雾霾的主要原因，它们在带给我们快捷方便、赏心悦目的同时，也悄悄给我们带来了意想不到的后果。
雾霾的天气，我们呼吸的是混浊的气体。
空气中的霾会引起肺炎、咽喉炎、气管炎、心脏衰落等疾病。
1952年，英国伦敦的那场大雾似无形的杀手，在短短五天内就夺取了4000人的生命，在之后两个月内有夺去了8000人的生命，可见大雾的威力，也该给我们敲响了警钟。
我们要的是清新的空气，要的是健康的体魄。
请不要以牺牲健康为代价，而换来所谓的美好生活。
少开车，绿色出行，多种树，保护森林。
治霾，从我做起。

③ 关于介绍北京八达岭长城英语作文
关于长城的英语作文(中英对照)如下：

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.

This is the origin of the name Of the "10,000-li Great Wall".
长城的建设开始于公元前第七世纪在周朝诸侯国在该国北部地区建立自己的墙壁，用于国防目的。秦国统一中国后，于公元前221年，它加入了墙壁，把侵略者从匈奴部落在北美和扩展到10000多个锂或5000公里。这是名称由来的“长城””。
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.
