小的时候，我经常梦到我居住在一个美丽的城市，城市被花儿和树木覆盖着，我可以感受每一阵清风亲吻我的每寸肌肤，可以感受大自然给予我的最纯正空气，一切都是那么美好，但是这些都只是我的一个梦而已。

    如今再看看我们的周围，天空它不再是湛蓝的，大片的土地不再弥漫着自然的气息，几乎所有的东西都失去了它最本质的美丽。

    那么到底是什么造成了这些呢？

    一.空气污染。据我所知，空气污染是如今世界上最严重的问题之一。人们大量开车使空气遭到污染，汽车排出污染气体造成了疾病甚至死亡。

    二.白色污染。白色污染是由于肆意乱用大量塑料产生的，塑料袋给我们的生活带来了便利，但同时也给环境保护带来了很大压力，在中国每天大概有三万塑料袋被使用，这是一个很糟糕的现象。

    三.水污染。近些年来，随着我国工业飞速发展，水污染也日益严重。在近两年之间我国共发生了140多起水污染事件，全国每年水污染事件都在1700起以上。

    朋友们，这些庞大的数字足以向我们证明一切，但是我们却始终没有从中意识到任何危机感。

    相反我们却渐渐变了，我们开始戴口罩，因为我们并不知道下一秒会有多少个PM 2.5吸入我们的肺里；我们开始抱怨着生活在这样一个糟糕的世界；我们开始恨那些大量排放污染物的工厂，最后我们失去了信心选择顺其自然；但是我的朋友，请你停下抱怨与憎恨，那些不正是我们人类自己的同胞做的事情吗？少数的抱怨和憎恨并不能改变什么，作为学生，我们确实不能为环境做出太大的贡献，但是我们可以尽我们所能去改变我们的环境，因为我们不仅是环境恶化的见证者也是最应该为之付出行动的一代人，那么我们应该怎样做呢？仅仅说保护环境、杜绝污染、杜绝浪费等等吗？不！朋友们，我们应该付出实际行动。

    想一想，我们是否应该抛开大量开发土地赚钱发财的想法，我们是否应该停下匆忙的脚步，弯下腰捡起一片垃圾，哪怕只是一小片；我们是否应该伸出手关上那正在滴水的水龙头？

    朋友们，真正贡献不是言辞，而是行动。”停下抱怨，让我们携手为我们的家园更为我们的未来付出真正的行动！

  Hello， everyone ! I am Madina from Class Two. Today I am going to talk about the beautiful world.

  When I was young, I often dreamt of living in a beautiful city,whichwas covered with green trees and beautiful flowers. I could feel the fresh breeze kiss each part of my skin and I could feel the pure air that naturebestowsme in my every breath. Everything was so wonderful. but thatwas onlya dream of mine.Nowadays ,Let’s look at all things around us again, The sky is no longer clean and blue. The field is no longer full of natural plants; almost every thing has lost its natural beauty.

  So what make the world become like this?

  Firstly, air pollution. As far as I know, Air pollution is one of the most serious problems in the world today. People make the air dirty with machines. Machines produce gases and smoke. Badly polluted air causes sickness and even death.

  Secondly, white pollution. The problem of“white pollution”is caused by used plastic. It is becoming serious; The plastic shopping bags play an important role in our life. But, In China about three billion plastic shopping bags are consumed every day, which results in a great waste of resources and heavy environmental pollution.

  Thirdly, the water pollution. In recent years, with the rapid development of China's industries, river pollution is becoming more and more serious. During these two years, there are more than 140 water pollution accidents in our country everytwo to three years. And the national water pollution accidents each year are more than 1700.

  Friends, All of the hugedatas are enough to prove everything.

  However, we didn’t realize its huge potential damage to us.

  In contrast, we start to wear masks, because we don't know how many PM2.5 will be sucked into our lungs next second. We begin to complain about the bad life, We start to hate those who discharge factory which pollute the environment a lot. Finally, we lose our confidence and choose to let it go.But my friend, would you please stop complaining and hating? Those people who make the environment become bad are us humans. That’s for sure. Complaints and hates don’t change anything. As a student, we are not only a witness to the pollution of the environment but also the people who should take action. So what should we do?

  Think about it, whether we should give up the idea of making a lot of money from environment? whether we should stop and bend down to pick up a piece of junk, even just a small piece? whether we should turn off the dripping tap? Friends, our contribution to the environment is not words, but actions. "Stop complaining and sighing, Let us work together for our beautiful world! Hand in hand.
