我国雾霾,近几年不仅仅变成国人谈论的热点论题,更是变成了世界谈论的热点论题。在托福阅览中,咱们可以将我国雾霾的一些常识作为托福阅览布景常识来知道。托福代报搜集了一些关于我国雾霾的常识,期望下次托福考试就考这样的论题,一同跟着托福代报来看看吧!

  Longtime exposure to particulate matter especially the particulate matter smaller than 2.5 micrometers (PM2.5) which can go directly to the alveoli of the lungs, is a major health hazard.

  专家称,长期呼吸空气中的颗粒物,特别是直径小于2.5微米的可入肺颗粒物(PM2.5)对人体安康损害很大。

  文中的PM2.5即是指“可入肺颗粒物”,PM的英文全称为particulate matter(微粒物、悬浮微粒),PM2.5即是指大气中直径小于或等于2.5微米的颗粒物,可直接进入人体的alveoli of the lungs(肺泡),也称为“可入肺颗粒物”,它的直径还不到人头发丝粗细的1/20。PM2.5首要来自vehicle exhaust(机动车尾气尘)、燃油尘、硫酸盐、餐饮油烟尘、修建水泥尘、煤烟尘和硝酸盐等。

  PM2.5粒径小,这种fine particles(纤细颗粒)富含很多的toxic and harmful substance(有毒、有害物质)且在大气中的逗留时间长、输送距离远,因而对人体安康和大气环境质量的影响更大。往后,运用PM2.5 measurement(PM2.5规范)进行air quality monitoring(空气质量监测)正变成全球趋势。

  迩来很火的词PM2.5是指大气中直径小于或等于2.5微米的颗粒物,也称为可入肺颗粒物。咱们期望愈加严格的空气规范将提醒更多的环境损害,进步大众的认识。

  China’s environmental authorities are to implement new air quality standards which will now measure some of the smallest and most damaging particles in the air. In many cities, the public are being consulted over the introduction of the new standards ,which will find out just how clean the air really is.

  我国的环境部门将履行新的空气质量规范,将丈量空气中一些最小、伤害最大的颗粒。在许多城市,民众正被询问到新规范的引进,这将知道到空气实际上有多纯洁。

  Smog in Beijing. Smog in Shanghai. Smog in Hangzhou - During recent months, dense pollution has frequently blanketed many cities in China. Sometimes visibility drops to less than 1 kilometer, causing serious traffic jams, flight delays and highway closures.

  北京的烟雾。上海的烟雾。杭州的烟雾——近来几个月,浓度大的污染经常笼罩着我国的城市。有时,能见度下降到1千米以下,引发了严峻的交通阻塞,航班延误和公路封闭。

  It has also raised public awareness of the issue. Ma Jun has been conducting environmental research since the mid 1990s and in 2006, he founded his own NGO in Beijing.

  它也进步了这个问题的公共认识。马军从上个实际90年代中期就开端进行环境研讨,2006年,他在北京成立自个的非政府安排。

  The Ministry of Environmental Protection’s newly published air quality standard includes monitoring of PM2.5 - a kind of air particle with a diameter of 2.5 microns or less. These particulates are small enough to penetrate human lung tissue, causing severe health problems. The revised standard is now open for public input and will tjinyan effect from 2016.

  环保局新近发布的空气质量规范包含了PM2.5的监测——PM2.5是一种直径等于或小于2.5微米的空气颗粒。这些颗粒足够小,能进入人的肺安排,引发严峻的安康问题。新修正的规范现在开放大众投入,从2016年开端收效。

  Responding to the new air quality standard, several cities, including Shanghai and Nanjing, announced that they are preparing pilot programs that will start to monitor and publish PM 2.5 levels soon. Experts believe that the monitoring results in some cities might not initially meet international standards.

  作为对新的空气质量规范的呼应,包含上海、南京在内的一些城市宣告,他们正在准备试点方案,很快将开端监测、发布PM2.4水平。专家认为,一些城市的监测结果开端可能达不到世界规范。

  Stricter air standards will reveal more environmental hazards and raise public awareness, which should certainly help the government’s aim of providing cleaner, healthier air.

  愈加严格的空气规范将提醒更多的环境损害,进步大众的认识,这无疑有助于政府供给更清洗、更安康的空气的方针。

  以上即是我国雾霾的有关常识介绍,除了雾霾这个托福阅览布景常识以外,托福代报还期望同学们可以关注实事,多堆集一些关于科学、人文、地舆等有关方面的常识,这些常识的堆集对托福阅览,托福白话,托福听力的协助都是很大的。最后,托福代报祝愿同学们可以顺利通过考试
