At this moment in time, no pollution has received more abuse than PM2.5 which refers to particles with diameter less than 2.5 pm and can easily penetrate the membrane of lung cell. These tiny particles are doomed to cause serious damage to our health. With time going by, there’s no denying that our pollution around us is on a rapid rise from last decade. So how can we restrict the emission and reduce the PM2.5 index？
Attitudes towards this issue vary from person to person. There’s a part of our citizens who always go into raptures at the mere mention of authoritative restriction and punishment. They tend to live under the illusion that more severe punishment will certainly exert more positive effect.
From my perspective, what they fail to take into consideration is the basic fact that punishment is only a small part of the measures .Assuming that if the company can bring in more money by emitting arbitrarily, they’ll do that consecutively, regardless of fine.
As far as I’m concerned, regulations and restrictions ought to be integrated with instruction of improving technology and constitution of economy. Only with much advanced technology and rational construction of economy can we solve the pollution problems in the essence. At the same time, it’s necessary for us to plant more trees to enhance our environment（英语四级作文 www.lyy5.com）.
It’s almost conspicuous that we are going to live with and fight against PM2.5 in the foreseeable future .We surely have a long way to go , so let’s maintain our confidence ,fortitude and perseverance. And we will conquer PM2.5 in the end.

此时此刻，没有任何一种污染物受到比PM2.5更多的批评了，PM2.5指的是直径小于2.5pm的可以轻易穿过肺部细胞的颗粒物。这些细小的颗粒物必然会对我们的身体健康造成严重的影响。随着时间的流逝，不可否认从十年前开始我们身边的污染正在迅速增加。那么，我们应当如何减少污染排放从而减少PM2.5指数呢？
不同的人对这个话题有着不同的看法。有一部分公民往往一提到让政府加大限制和处罚力度就心花怒放。他们似乎错误的认为更加强有力的处罚措施一定会产生更加积极的效果。
从我的角度来看，他们没有考虑到一个基本的事实是惩罚措施只是所有措施中的一小部分。假设如果公司可以通过任意排放赚更多的钱，他们一定会忽视罚款继续这样做下去的。
我认为管理条例和限制手段应当和高科技的引入和经济发展方式的转变结合起来。只有拥有了更加先进的科技和正确的经济结构，我们才会从本质上解决污染问题。与此同时，我们也应当种植更多的树木来改善我们的环境。
很显然，我们必然在未来和PM2.5生活在一起并与之斗争。我们必然还有一条很长的道路要走，所以让我们保持我们的信心，坚持不懈的信念，最后我们必然会征服PM2.5。
