June 15th, 2006

Dear Sir or Madam,

Thank you for taking time to read this letter. As the problem of food safety has been becoming worse and worse nowadays, I am obliged to write to you.

Several days ago, one of my classmates came back from supermarket with a large bag of food. Because of having found a new style of tinned?ish in the food store, she was very glad. Several other roommates were invited to enjoy the “mouth?atering chicken”. Unfortunately, after finishing the food, all of my three friends had stomachaches and vomited, their faces having become paler and paler. Due to sensitivity to that kind of tinned food, I escaped that suffer. At that time, my mind went blank. I dialed the emergency number with my trembling hand, therefore they were quickly sent to hospital. The doctor said they were lucky to be out of danger because they did not eat too much of that rotten fish and were hospitalized on time.

This is the matter that happened around me which made me realize the seriousness of the food safety problem. I sincerely hope that the whole society could attach much importance to this issue.

Thanks!

Yours,

Julie

About two weeks from now, college students will begin to enjoy their long summer holidays. Many are looking for odd jobs, of which tutoring is almost the most popular one.

These students say, by doing pan-time jobs, they can not only make some money for next terms tuition, but also enrich their holidays. They prefer to be tutors because this has more to do with what they have learned in class.

As a student, I myself have also been a tutor. But I didnt wait in line until I was chosen. I put up an advertisement with my school scripts attached. So, my suggestion to my fellow students is: be a tutor only when you are good at your courses.

篇3:保护环境,拒绝白色污染的作文

全文共 544 字

+ 加入清单

塑料的发明和应用给人们的生产和生活带来了极大的方便;上街买东西不用再带篮子,有塑料袋为你服务;出差也不用再带牙刷,宾馆早就为你准备齐全……可是这些用后随手丢弃的塑料制品却给我们的生活环境留下了百处隐患。

使用后四处散制的塑料制品,一方面影响市容和景观,带来“视觉污染”;另一方面,塑料制品“潜在危害”,掩埋,不仅占用土地,还造成土壤污染、地下水污染、焚烧,会产生有刺激性的毒气体,污染大气环境,损害人体健康。

针对日益严重的白色污染及其危害,各国开展了防治白色污染的研究,光降解塑料、生物降解塑料、光生物降解塑料、水降解塑料均已诞生,但是回收废塑料并使之资源化仍是解决白色污染的根本途径。我国提出了“回收为主,替代为辅”的方针,并相继出台了如禁止使用泡沫塑料盒、限塑令等一系列相关法规:

2007年12月31日,国务院办公厅下发“限塑令”,明确规定:“从2008年6月1日起,在全国范围内禁止生产、销售、使用厚度小于0。025毫米的塑料袋,在所有超市、商场、集贸市场等商品零售所实行塑料购物袋有偿使用制度,一律不得免费提供塑料袋。”

防治白色污染,我的建议是:不使用一次性餐具;家里来客人不用一次性水杯;塑料多次使用;废弃塑料制品卖给废品收购者;开发可降解塑料;加强环保宣传,提高公民的环保意识!

风,呼呼地吹着,雨,哗哗地下着,你或许不知道,这是环境的哭泣。

所有的生物,都是环境的儿女,可现在,却,哎,却让人类毁灭了好些。你想:杀人蜂是人类培育的,吉丁虫,早就移到了印度;大闪蝶,在中国早以不见了踪影;那捕鸟蛛,本该是活着来,可早也成了标本;那……可怜这些可爱的动物,只剩下三三两两地了。就因为人类啊!昆虫,有的自相残杀,因为环境的污染,有的生成了怪物,甚至失去生育能力,造成了一个可怕的事实―绝种!

在昆虫界来看,昆虫太惨了!蚕结了茧,被煮了;吉丁虫一停下来就被抓,做了标本,不明不白、迷迷糊糊地上了天堂;有的药用的昆虫,绝了种,人得了那种非用虫子治的病,也只好等待死神大驾光临了!哎,人类污染环境、捕捉昆虫,不是等于,等于―自杀吗!?还有的人因为自已污染了环境,害了自已和亲人。这,是那可恨的人应该得到的悲惨的结果,那是他们自已酿的苦酒,由他们自已去细细地、慢慢地品尝,这也是一个―血的报应啊!

看了这些,听了这些,这些也凝结成了一句不用翻译的话―为保护环境而呼吁:“不要再伤害环境,不要伤害我们的朋友,不要,不要再伤害自已啦!”

这一句话不用翻译,这一句话发自全世界人的内心,这一句话是最难实现的,这一句话也是最好实现的!只要我们能拉起手,把环境弄好,从每一张小纸片,每一个“白色污染”做起,我们一定能行!我们都要牢牢地、牢牢地记住:团结就是力量!

每当我看到蔚蓝的天空被烟尘层层遮盖的时候,我就会想起保护环多么重要;每当我遇到沙尘暴的时候,我就会为植被的破坏,水土的流失,土地的沙化而担忧;每当我看到一条清澈的小溪被附近工厂所污染的时候,我就会为那些小溪中的小生命捏一把汗;每当我看到大街上不满了废纸和白色垃圾时,我就会大声疾呼:“给我一个清新的生活环境吧!”

科学的发展为人类创造了大量财富,同时也给人类带来了难以避免的灾难:水土流失、土地沙化、淡水减少、动物灭绝、物种减少等环境的破坏。在这种严峻的形式下,我们能无动于衷吗?一个小学生,能为环保做些什么呢?想来想去,还是从我做起。

在家中,我是奶奶的好帮手,给奶奶讲对垃圾也应该按照再生垃圾、不可再生垃圾、和有害垃圾进行分装处理,我们家设立了两个废旧物品箱,一个装废纸、废塑料、一个装果皮。在植树节那天,我还用自己的压岁钱买两株果树和爸爸妈妈一起栽种在森林公园,心中的高兴可想而知。在学校,作为小组长的我,就更加努力了。我和同学们坚持举办月刊环保手抄报,通过搜集大量的环保知识资料、漫画进行宣传,使每一个同学养成了良好的环保习惯。由于许多人对废旧电池的污染认识不足,随意丢弃废电池的现象十分严重,我向校长写了一封“废旧电池该往哪儿仍”的倡议书,在学校设立了废旧电池回收箱。在街上,看见一位阿姨正将吃的口香糖随地突出,我便会毫不忧豫的跑过去,告诉她,阿姨请别把

它吐在地上,而应该用纸包起来,放进垃圾箱中。试想,如果每块吃过的口香糖都被吐在地上,后果将会怎样?

我想:如果我们瓜洲县的小学生都这样做,这里的天空会变得更蓝更美,空气会变得更加洁净清新,自来水喝起来更香更甜,城市也会变得更加美丽!新世纪得笑容会更加灿烂!让我们争当环保小卫士吧!让我们大声呼喊:“保护环境,从我做起!”

有欲害花者,无仁;无欲护花者,无爱。草木如歌,让我们用最美的声音来诠释她。——题记

保护环境,这个既简单有困难的话语,实现它只有靠自己,最近在《我爱祖国的蓝天》一书中,我看到了这样一句话:“因为人类没有环保意识,致使大气污染越来越严重,水资源危机日趋加深,土壤流失正逐渐加重,森林正一天天减少,许多动植物濒临灭绝,城市正越来越不适合人类居住……”

看到这,我不禁往往那已经不再天蓝,不再充满幻想的天空,它承载的全球60多亿人的希望。

所以保护环境,是使每个有道德的人所必须做的事,因为这个大环境是人类生存的宝贵的地方。人不仅来自于自然,也受之与自然。自然环境使人们赖以生存和发展的必要物质条件。当今世界,环境污染,生态平衡现象日趋严重。现在,全球森林正以每460万公顷的速度减少;地球上供优2亿人的生活在缺水区。我国近几年来,由于人们的环境意识薄弱,生态破坏严重,环境问题更为严峻。

1998年长江,嫩江,松花江流域的大洪灾以及近几年北京愈来愈重的风沙。特别是今年4月上旬,中旬的沙尘暴涉及的面积之广,风力之大,尘土之浓,持续时间之长,更是历史上罕见的。这一系列的自然灾害已向国人重锤击响保护环境的警钟。人类只有一个地球,自毁地球无异于毁灭自己生存的家园。树立环保意识已成为全世界各人民的共同要求。爱山爱水爱林爱鸟爱人类,护天护地护花护草护环境。

我在看了《十万个为什么》中太阳会有耀斑之后,做了一个这样的梦……

在飞船上的2040年,我已经成为了飞船有名的科学家了。要解决现在飞船上最严峻的问题——环境污染

在2030年时,养育世间万物的太阳居然爆炸了,吞噬了地球。我们造好了飞船上的最后一个零件,飞出了地球。日复一日,年复一年,我们不断修复飞船,但因为当时走得匆忙,只带了一些菜子和猪肉。除了造飞船时种下的草,就只剩一棵树了。

十年过去了,草基本都死了,整个飞船进入了严重污染期:垃圾没地方分解,吸收;废水也不能被自然净化;氧气也越来越少……

在这时,我提取了草,树,菜,猪的基因,合成了一种叫“草树菜猪”的东西。这种东西可种植,长出来后是树一样高的草。煮熟后,是一种有菜的颜色和营养,有猪的香味和口感的食物。未煮熟的时候十分坚硬,可以造房子。也可以像草一样给人们提供氧气。

那么大一个飞船一棵“草树菜猪”怎么够呢?我用克隆机克隆了成千上万的“草树菜猪”,种植到飞船的每一个角落。

经过不懈努力,终于,污染危机解除了。

虽然这只是一个梦,但是我们如果还不加节制的污染,浪费,这会不会变成真的呢?

我们从现在开始保护我们的地球妈妈吧!

最近,我对我家居住的卫校小区的空气质量进行了调查。经过这次调查,我发现小区的空气遭到了严重的污染,主要污染源是:小区旁的餐馆排放出的油烟;过路的车辆排放出的废气;附近的梅峰寺后山有人在烧垃圾,烟雾弥漫。正是这些有害气体污染了原本清新的空气。这些被有害气体污染了的空气,会对人体健康产生不利的影响,还会对周围的花草树木的生长造成了极坏的影响。

保护环境,人人有则。为了防止家乡空气受到污染,我想我们大家可以做好多事,为防止家乡空气受到污染献自己的一份力量。第一,可以给小区旁的餐馆写一份建议书,建议餐馆把油烟经过处理再排放到空气中去。还要改进汽车发动机,减少废气的排放;第二,大家要爱护花草树木,因为花草树木是氧气制造厂,空气过滤器,可以有效净化空气;第三,我们要注意搞好环境卫生,不乱扔垃圾,不随地吐痰等。

啊!我们从小养成保护环境的好习惯,养成良好的文明卫生习惯。大家动员起来吧!让我们生活的环境更加美好!

现在的小区生活使许多人不爱护环境,比如家离垃圾桶不远,而生活垃圾就喜欢往下扔,不愿意拎下来放进垃圾桶里,乱扔垃圾使空气散发出阵阵臭味,还有汽车排出的尾气又黑又脏,人类吸了容易生病,还有工厂里排放出的工业用水会污染我们的饮用水,人们喝了这水就会生病。。。。。。

我长大要发明一种药水,一滴就可以自动分解我们的生活垃圾,使它不再发臭而是会散发出阵阵香味。二滴放在汽车尾部使汽车排放出来的气一下变成无色无味的空气。三滴可以把工产排放出来的污水变得清澈见底,鱼儿在河里欢快的游来游去。

这些只是我的想象,具体的做法应该首先,在我们的小区周围竖立牌子上面写着“请不要乱扔垃圾,爱护环境”这样会使人们注意,就不会乱扔垃圾。然后在公路的两旁多种一些树木使汽车排出的尾气被树树木吸收,最好要用太阳能汽车又环保又省油。最后,每个工厂要做一个排污吸收管和污水净化池,就会使工产附近的树木生机勃勃,空气清新舒畅。

大家应该从我做起,从身边的小事做起爱护自己可爱的家园。毕竟,我们只有一个地球。

随着科技的不断发展,汽车的不断增多,排放的废气已经造成了严重的污染,或许,几年后的子孙后代、几百年后的大家,或许会因为大气污染而死亡。现在,地球上每一年都有百分之二十的人因为饮用了受到污染的水而死亡,如果这样延续下去,地球在几万年后岂不是变得光秃秃、像月球一样了?

据科学家的统计,每一年,每一月都有百分之二十多的树木因为废气污染而枯萎。百分之八十多对我们有益的细菌死亡,大家或许会觉得很夸张,但这是事实。其次还有受到污染的废水、废气等。人类有错吗?

我多么希望大家能珍惜我们身边的每一个事物,每一只动物,每一只有益的细菌,因为,很有可能,在几万年后的今天,他们都没有了。

动物对人类发起了警告;

细菌对人类发起了警告;

每一条无辜的生命对我们发起了警告。

在十年前的中国,大气污染问题对于普通民众来说可能是个比较飘渺的话题。正如空气本身的性质一样,看不见摸不着却无处不在。而专家学者们则主要关注的是对于工业生产,燃煤发电所产生的硫氧化物的处理和汽车尾气中氮氧化物的处理。十年时间飞逝,随着中国经济的迅速发展,人们生活水平的不断提高,人们开始关注生活的质量问题。与其同时越发严重的正是中国以牺牲环境为代价发展经济所带来的环境问题,其中大气污染问题尤其明显。这几年来关于温室气体和温室效应的话题被讨论得沸沸扬扬,专家们各有其立场,但对于普通百姓来说,全球变暖问题似乎仍很遥远。对于温室气体所带来的全球变暖,海平面上升,冰川融化,动植物灭亡的问题,人们大多数是在电视新闻或报刊杂志上看到,恶劣天气的频发也并不是发生在世界每个角落。相比于温室气体所带的大气污染问题,人们开始关注更多的便是最近发生在北京,广州,武汉等多地的灰霾问题。尤其是在北京持续很久的灰霾严重影响了当地人们的日常生活和身体健康,更是引起了广大专家学者和普通民众的高度关注。而其实对于灰霾现象,国外专家学者很多年前便开始研究。

那么何为灰霾?灰霾是导致近地面大气浑浊的多种空气污染物的混合体。构成灰霾的主要污染物是硝酸盐、硫酸盐、有机碳、元素碳、等固体细颗粒物(PM2.5)和臭氧()、二氧化氮()、二氧化硫()、挥发性有机物()等气态污染物。灰霾往往与天然污染源的排放和二次污染污染物的形成有关,还与一定的气象条件和地形有关。我们现在最关注的同时也最难解决的室外污染物之一是可吸入颗粒物。可吸入颗粒物被分类为两种,直径小于2.5微米的颗粒物(PM2.5)和直径小于10微米的颗粒物(PM10)。虽然两种形式的颗粒物都对人类健康有极大的危害,PM2.5被普遍认为是更危险的,因为它的体积小,大约只有人类头发宽度的1/30。人们在呼吸时,PM2.5可以进入人类肺组织深处,甚至进入血液,造成严重的健康问题。同时更小的颗粒物在大气中可以有较长的停留时间。因此,PM2.5可以传播的更远,停留在空气的时间越长,影响更大的人口。PM2.5和PM10的主要来源包括机动车,电厂和其他工业源,以及生物质的燃烧。其中一个主要的来源是柴油为动力的车辆。这些污染源相结合,可以在城市或农村地区天空一片阴霾,而且往往发生在下午时段。

对于容易形成灰霾的城市,除了城市当地工业污染,汽车尾气的影响以外,特定的地形导致污染物的难以扩散也是灰霾形成的主要原因,像美国的洛杉矶,还有前面提到的受灰霾影响的北京和武汉都受到了地形的影响。洛杉矶市三面被群山包围,当地空气干燥,白天阳光充足。到了晚上,地表面冷却很快。地面附近的空气变冷,而上层空气都比较热,形成逆温。北京市位于华北平原的西北边缘,背靠太行山余脉和燕山山脉,面对辽阔的华北平原,东南距渤海约150公里, 地处暖温带半湿润地区,气候属于暖温带半湿润大陆性季风气候,四季分明,春季多风和沙尘,夏季炎热多雨,秋季晴朗干燥,冬季寒冷且大风猛烈。武汉市则居于内陆、距海洋远,周围地形如盆地,集热容易散热难,河湖多、晚上水汽多,城市热岛效应和伏旱时副高控制明显。通过比较以上3个城市的情况可以发现它们都是较大的工业城市,而且城市海拔较低,周围至少有一面是高地,都分布在低于南北纬50度的地方。这些地区夏季阳光明媚,天气温暖干燥。在城市的盆地地区,逆温现象十分普遍。夏季的阳光使地面温度升高,城市街道和建筑物迅速升温,与炎热的物体表面接触的空气温度升高。通过对流空气向上运动,但它却不能穿透逆温层,因为上面的空气温度更暖且密度更小。空气聚集,但连续的对流形成了垂直的循环,使空气完全混合在一起。从建筑物和汽车废气释放出的气体和颗粒也都聚集在逆温层下,通过对流把聚集的空气彻底混合。这样导致污染物无法快速扩散而聚集,大大增加了当地的污染物浓度。

城市内部灰霾的形成也同样受到了这种类似地形的影响,学者称它为街谷模型。随着城市化的加速,城市及城市周边的自然生态系统逐渐被人工生态系统取代,取而代之的是钢筋混凝土浇筑的高楼与马路,很容易形成城市街道峡谷。这种城市街道峡谷是指两侧有连续,高大建筑物的狭长城市街道空间。在这种地形下,上层大气在进入城市时,风速迅速降低并产生特殊的湍流,使街谷内的流场完全不同于上层大气。而气流对污染物具有显著的运输、稀释、和扩散作用,因此,对城市街谷内污染物的浓度、分布有着很大影响。北京的灰霾现象正是因为污染物积聚难以扩散而导致北京的灰霾持续了如此之久。有相关专家的研究发现,除了通过控制排放源,增大扩散和增加沉积率来降低大气中污染颗粒物的浓度以外,地面的性质也影响着颗粒物的浓度。有研究表明植被对城市空气质量能有接近5%的提高。在城市,尤其是在城市街谷地带种植植被能通过增加沉积作用而降低60%的可吸入颗粒物(PM)浓度和40%的二氧化氮(NO2)浓度。因此,通过对植被的合理利用能过创造一个有效的城市污染过滤膜,对密集城市地带空气质量的提高有着快速有效并且持续性的影响。

灰霾问题不是一个暂时性的问题,相反它是一个长久的问题,从它如何形成,加剧到我们如何解决治理并消除都需要一段很长的时间。

灰霾现象,它只是地球环境污染的一个缩影。我们更应该探究它的根源问题,什么才是它形成的根源,什么才是它加剧的根源。我们没法通过改变天然的气候和地形来解决城市灰霾问题,但我们可以通过减少排放源,通过增加植被,加强城市绿化来阻止灰霾的加剧。人类的不断进步使得人们在追求高科技的同时却忘记了自然本身的无穷力量。越来越高的大楼,越来越发达便利的交通,相反的却是城市越来越差的生活环境。在灰色的钢筋水泥世界里生活久了,人们是否会怀念那晴朗的蓝天,向往呼吸新鲜的空气和在那充满生机的绿色大自然世界里生活。

在2016年11月30日,对于中国人来说,这是一个值得载入史册的日子,那就是被国际气象界誉为“中国第五大发明"的“二十四节气”申遗成功,获批列入联合国教科文组织人类非物质文化遗产代表作名录。

作为中国人,我可以很自豪的说:“这就是中国人的骄傲”我们的老祖宗曾经说过:立春要迎春,清明要踏青,冬至要吃饺子,这些都是我们祖宗的智慧结晶,值得为我们后代人所用。但是纵观现在的社会,大多数人却热衷于过西方人的节日,什么情人节啦,圣诞节啦等这些节日都搞得红红火火。而且有些有钱的人为了过得热闹一些,而不惜下血本搞。这也不符合中国的传统美德。除了这些,更可悲的是。有人问你说二十四节气是什么,我相信有很多人都会回答说不知道,如果这么回答就是一件很可悲的事情了。

但是,这也不能全怪他们,当今世界随着工业化的发展。海平面上升,全球气候变暖……这一系列的国际问题导致了如今的`“二十四节气”有些跟今天的气候物候不相符了。比如说:节气是大雪,但艳阳高照,热的要命。还有比如5月下旬的小满,古时候是小麦快成熟的时候,但如今却是到收割的时候了。这毋庸置疑是全球气候变暖最好的体现,工业化发展固然很重要,但是保护环境,传承中华传统的文化更重要,因为这是我们的祖先历经一代又一代人总结出来的自然发展规律,我们有责任,有义务去传承,并且发扬光大,做这些是我们作为炎黄子孙所应当做的事情,我们不能让我们祖先的聪明智慧失传,应该一代接一代的传承下去。

保护环境,人人有责!让我们一起来保护环境,传承中华文化吧!

Should We Help Strangers?

Recently our class had a discussion about whether we should help

strangers.Different students have different opinions.

Some think we should try to help strangers. Helping others is a virtue,and

helping others is helping ourselves.We may come across some trouble and need

others help some day.If everyone isnt willing to help us just because we are

strangers to them,its hard to imagine what our world will be like.

However,some are afraid that helping others can sometimes bring us

trouble.Sometimes we are just misunderstood and even have to pay the cost of

kindness.

In my opinion,we should try our best to help others when they are in need

of help,but we should also protect ourselves from getting into trouble.If

everyone tries a little kindness,our world will be full of love.
